1. Oorsig van die troeteldiervoedselbedryf en -verwerkingskenmerke
1.1 Huidige situasie en ontwikkelingstendens van die troeteldiervoedselbedryf
In onlangse jare, die wêreldwye troeteldiervoedselmark het 'n bestendige groeitendens getoon. Gedryf deur faktore soos die toename in die aantal troeteldiere, die opgradering van troeteldierverbruikkonsepte, en die verbetering van inwoners’ koopkrag, die vraag na hoë gehalte, voedsame en funksionele troeteldierkos het aanhou styg. Volgens relevante datastatistieke, die wêreldwye troeteldiervoedselmark het oorskry 100 miljard Amerikaanse dollars, en dit sal na verwagting 'n groeikoers van handhaaf 5%-8% in die volgende paar jaar. Onder hulle, droë opgeblase troeteldierkos, as die mees hoofstroom produk tipe, verantwoordelik vir meer as 60% van die totale troeteldierkosmark, gevolg deur nat ingemaakte produkte, halfnat produkte en troeteldierhappies.
Die ontwikkelingstendens van die troeteldierkosbedryf word hoofsaaklik in drie aspekte weerspieël: eers, voeding en gesondheid. Troeteldiereienaars gee al hoe meer aandag aan die voedingssamestelling van troeteldierkos, en produkte met natuurlike, toevoeging-vry, funksioneel (soos haarskoonheid, maag voeding, gewig beheer) eienskappe is meer gewild; tweede, diversifikasie van produktipes. Met die verryking van troeteldiertipes en die individuele behoeftes van troeteldiereienaars, troeteldierkos het geleidelik ontwikkel tot segmentering, soos troeteldierkos vir verskillende ouderdomme (hondjies, volwasse honde, bejaarde honde), verskillende rasse, en verskillende fisiese toestande; derde, intelligensie en doeltreffendheid van verwerkingstegnologie. Om aan die grootskaalse produksievraag te voldoen en die stabiliteit van produkkwaliteit te verseker, troeteldiervoedselverwerkingsondernemings stel voortdurend gevorderde verwerkingstoerusting en intelligente beheerstelsels bekend om produksiedoeltreffendheid te verbeter en arbeidskoste te verminder.
Teen hierdie agtergrond, ekstrusie blaas tegnologie, as die kerntegnologie van troeteldiervoedselverwerking (veral droë gepofte produkte), het die sleutel geword om die kwaliteit van troeteldierkos en die mededingendheid van ondernemings te bepaal. Ons professionele ekstrueerders vir troeteldierkosproduksie word ontwikkel in reaksie op die kenmerke van die bedryf en markaanvraag, wat die pynpunte in troeteldiervoedselverwerking effektief kan oplos en ondernemings kan help om hoëgehalte en doeltreffende produksie te bereik.
1.2 Klassifikasie van troeteldierkos en die verwerkingskenmerke daarvan
Troeteldierkos het 'n verskeidenheid klassifikasiemetodes, wat volgens verwerkingstegnologie in verskillende tipes verdeel kan word, waterinhoud, produk vorm en gebruik. Onder hulle, volgens die verwerkingstegnologie en waterinhoud, troeteldierkos word hoofsaaklik in droë opgeblaasde produkte verdeel, semi-nat produkte, sagte opgeblase produkte, nat ingemaakte produkte en versnaperinge (of lekkernye). Elke tipe troeteldierkos het sy eie unieke verwerkingseienskappe en vereistes vir toerusting, soos volg:
1.2.1 Droë gepofte produkte:
Droë opgeblase troeteldierkos is die mees algemene tipe troeteldierkos, met 'n waterinhoud van 10%-12%. Sy belangrikste grondstowwe sluit vleismeel in, vismeel, graan (mielies, koring, rys), sojaboonmeel, vitamiene, minerale en ander bymiddels. Die verwerkingsproses van droë opgepofte produkte is nou verwant aan die opblaasproses, wat die gebruik van ekstrusie-poftoerusting vereis om die grondstowwe te verwerk tot korrelprodukte met eenvormige grootte, skerp smaak en goeie smaaklikheid. Die eienskappe van droë opgepofte produkte is lang raklewe, gerieflike berging en vervoer, en lae produksiekoste, wat geskik is vir grootskaalse produksie en gewild onder troeteldiereienaars is.
Die sleutelverwerkingsvereiste van droë opgeblaasde produkte is dat die grondstowwe volledig opgepof moet word, sodat die stysel in die grondstowwe ten volle gegelatien is, wat bevorderlik is vir die vertering en opname van troeteldiere. Terselfdertyd, die produk moet 'n sekere hardheid en skerpheid hê om aan die koubehoeftes van troeteldiere te voldoen en hul tande te help skoonmaak. Dit stel hoë vereistes aan die ekstrusiedruk, temperatuur en skroefspoed van die ekstruder.
1.2.2 Half-nat produkte:
Halfnat troeteldierkos het 'n waterinhoud van 25%-35%, wat tussen droë en nat produkte is. Die grondstowwe daarvan is soortgelyk aan droë opgepofte produkte, maar meer humectants (soos propileenglikol, sorbitol) word bygevoeg om die sagtheid en vog van die produk te behou. Die verwerkingsproses van halfnat produkte benodig ook pofbehandeling, maar die opblaasgraad is laer as dié van droë produkte. Die produk het die eienskappe van sagte smaak en goeie smaaklikheid, wat geskik is vir troeteldiere met swak kouvermoë (soos bejaarde troeteldiere, siek troeteldiere).
Die verwerkingsmoeilikheid van semi-nat produkte lê in die beheer van waterinhoud en die voorkoming van produk agteruitgang. Daarom, in die verwerkingsproses, dit is nodig om die temperatuur en humiditeit van elke skakel streng te beheer, en kies toepaslike preserveermiddels en bevogtigers om die raklewe van die produk te verseker.
1.2.3 Sag gepofte produkte:
Sag gepofte troeteldierkos het 'n waterinhoud van 15%-25%, wat 'n produk is tussen droë opgepofte en halfnat produkte. Die verwerkingsproses is soortgelyk aan dié van droë opgepofte produkte, maar die formule en ekstrusieparameters word aangepas om die produk sag en elasties te maak. Sag gepofte produkte kombineer die voordele van droë en halfnat produkte, met goeie smaaklikheid en maklike vertering, wat geskik is vir 'n verskeidenheid troeteldiere.
1.2.4 Maak ingemaakte produkte nat:
Nat ingemaakte troeteldierkos het 'n waterinhoud van meer as 70%, gebruik hoofsaaklik vars vleis, vis, groente en ander grondstowwe, wat deur kook verwerk word, inmaak, sterilisasie en ander prosesse. Anders as ander soorte produkte, nat ingemaakte produkte het nie pofbehandeling nodig nie, en hul kernverwerkingskakels is kook en sterilisasie. Die produk het die eienskappe van ryk voeding, sterk smaaklikheid en hoë voginhoud, wat geskik is vir troeteldiere wat nie van drinkwater hou nie of aanvullende voeding benodig.
Die sleutel tot die verwerking van nat ingemaakte produkte is om die varsheid en veiligheid van grondstowwe te verseker, en beheer die sterilisasietemperatuur en -tyd streng om skadelike bakterieë in die produk dood te maak en die raklewe te verleng. Terselfdertyd, dit is nodig om te verseker dat die voedingskomponente van die produk nie verlore gaan tydens die kook- en sterilisasieproses nie.
1.2.5 Troeteldierversnaperinge (of lekkernye):
Troeteldierhappies is hulpkos vir troeteldiere, hoofsaaklik gebruik om troeteldiere te beloon, verbeter hul bui en vul voeding aan. Die soorte troeteldierhappies is uiteenlopend, insluitend opgeblase versnaperinge, gedroogde vleis versnaperinge, rukkerige versnaperinge, tandheelkundige versnaperinge, ens. Onder hulle, gepofte versnaperinge maak 'n groot deel uit, en hul verwerkingsproses is soortgelyk aan droë opgepofte produkte, maar die formule is meer verfyn, en meer geurmiddels en funksionele bymiddels word bygevoeg om aan die smaak en funksionele behoeftes van troeteldiere te voldoen.
Troeteldierhappies het hoë vereistes vir smaak, voorkoms en funksionaliteit. Byvoorbeeld, tandheelkundige versnaperinge moet 'n sekere hardheid en tekstuur hê om die troeteldier se tande te help skoonmaak en tandsteen te voorkom; haarverfraaiende versnaperinge moet bestanddele soos lesitien byvoeg om die troeteldier se haarkwaliteit te help verbeter. Dit vereis dat die ekstruder goeie buigsaamheid en verstelbaarheid het om aan die verwerkingsbehoeftes van verskillende soorte versnaperinge te voldoen.
Dit is opmerklik dat behalwe vir ingemaakte produkte, meeste soorte troeteldierkos is nou verwant aan die opblaasproses. Opblaas is nie net die kern van die verwerking van troeteldierkos nie, maar beïnvloed ook die kwaliteit direk, smaak, voeding en verteerbaarheid van troeteldierkos. Daarom, die keuse van die regte ekstrusietoerusting en die bemeestering van die wetenskaplike ekstrusietegnologie is van kardinale belang vir troeteldiervoedselverwerkingsondernemings.
2. Kerntegnologie van troeteldiervoedselverwerking: Ekstrusie Puffing Tegnologie
Ekstrusie-poftegnologie is 'n sleutelverwerkingstegnologie wat vermenging integreer, knie, verhitting, ekstrusie en opblaas. Dit is wyd gebruik in die produksie van troeteldierkos as gevolg van die voordele van hoë produksiedoeltreffendheid, goeie kwaliteit van die produk, sterk aanpasbaarheid by grondstowwe en wye toepassingsreeks. In die verwerking van troeteldierkos, ekstrusie tegnologie word hoofsaaklik gebruik om die opblaas van grondstowwe te realiseer, laat die stysel gelatineer, die proteïen denatureur, en verbeter die smaaklikheid en verteerbaarheid van die produk. Terselfdertyd, dit kan ook skadelike bakterieë in die grondstowwe doodmaak, verseker die veiligheid van troeteldierkos.
2.1 Eienskappe van Troeteldierkos Grondstowwe en Vereistes vir Ekstrusie Toerusting
Die grondstowwe van troeteldierkos is hoofsaaklik vleisprodukte (soos vleismeel, vismeel, vars vleis), graan, sojaboonmeel, vitamiene, minerale en ander bymiddels. Onder hulle, vleisprodukte maak 'n groot deel uit, maak die produk sterk viskositeit. Hierdie eienskap stel spesiale vereistes vir ekstrusietoerusting voor:
Enkelskroef-ekstruders is nie geskik vir die ekonomiese produksie van troeteldierkos nie. Omdat die enkelskroef-ekstruder 'n smal skuifreeks het, swak pompvermoë en geen selfreinigende effek nie. Wanneer viskose materiale soos vleisprodukte verwerk word, dit is maklik om materiaalophoping te veroorsaak, blokkasie en ongelyke vermenging in die ekstrudervat, wat nie net produksiedoeltreffendheid beïnvloed nie, maar lei ook tot onstabiele produkkwaliteit. Daarby, die enkelskroef-ekstruder het hoë energieverbruik by die verwerking van hoëvet- en hoëproteïengrondstowwe, wat die produksiekoste van ondernemings verhoog.
Dubbelskroef-ekstruders, aan die ander kant, het ooglopende voordele in troeteldiervoedselproduksie. Hulle het 'n wyer skuifreeks, meer effektiewe pompeffek en selfreinigende effek, wat die probleme van materiaalviskositeit en akkumulasie effektief kan oplos. Die dubbelskroef-ekstruder kan die eenvormige vermenging realiseer, knie en ekstrusie van materiale, selfs wanneer grondstowwe met hoë vet- en varsvleisinhoud verwerk word, dit kan ook stabiele produksie en konsekwente produkkwaliteit verseker. Daarom, in die werklike produksie van troeteldierkos, dubbelskroef-ekstruders het die belangrikste manier geword om troeteldierkos te puff, en word wyd gebruik in die vervaardiging van droë opgeblaasde produkte, semi-nat produkte, sagte opgeblase produkte en troeteldierhappies.
2.2 Werksbeginsel van skroefekstrudering
Die skroef-ekstrusie-pofproses van troeteldierkos is 'n komplekse fisiese en chemiese proses, wat die interaksie van veelvuldige faktore soos temperatuur behels, druk, skuifkrag en tyd. Die spesifieke werksbeginsel is soos volg:
Eerstens, rou materiaal voorbehandeling. Die poeieragtige grondstowwe wat 'n sekere hoeveelheid stysel bevat (meer as 20%) word eenvormig volgens die formule gemeng, en dan na die temperapparaat gestuur vir temperbehandeling. Die doel van tempering is om die voginhoud en temperatuur van die materiale aan te pas, sodat die materiaal die ideale toestand kan bereik voordat dit die ekstruder binnegaan. Oor die algemeen, die voginhoud van die materiaal na tempering word beheer teen 10%–27%, en die temperatuur word tot 70~98℃ verhoog. Tydens die tempereringsproses, die materiaal absorbeer water eweredig, wat bevorderlik is vir die daaropvolgende gelatinisering van stysel en denaturering van proteïen, en kan ook die slytasie van die ekstruderskroef en -vat verminder.
Tweedens, ekstrusie en verhitting. Die geharde materiale gaan die skroef-ekstrusieholte deur die toevoertoestel binne. Die skroef-ekstrusieholte bestaan uit 'n skroef en 'n loop, en die volume van die ekstrusieholte neem geleidelik langs die asrigting af. Wanneer die skroef draai, dit stoot die materiaal voortdurend vorentoe, en die materiaal word geleidelik saamgepers onder die werking van die skroef en die loop, en die druk in die ekstrusieholte neem geleidelik toe. Die kompressieverhouding (die verhouding van die volume van die materiaal by die voerkant tot die volume by die ekstrusiekant) kan 4–10 bereik, which varies according to the type of pet food and the formula of raw materials.
During the process of being pushed and extruded by the screw, the materials are subjected to strong shear force and friction force. The shear force is generated by the relative movement between the screw and the barrel, asook tussen die skroefvlugte. It can break the particles of the materials, make the raw materials and additives mix more uniformly, and promote the gelatinization of starch and denaturation of protein. The friction force is generated between the materials and the inner wall of the barrel, as well as between the material particles, which can generate a lot of heat, which is conducive to the heating of the materials. Daarby, according to the processing needs, stoom kan deur die vatbaadjie vloei om die materiaal tussen die mure te verhit, sodat die materiale in die ekstrusieholte in 'n hoë-temperatuur- en hoëdruktoestand is. Die temperatuur in die ekstrusieholte word oor die algemeen beheer teen 120 ~ 180 ℃, en die druk word beheer teen 2~10MPa.
Derde, styselgelatinisering en proteïendenaturering. Onder die werking van hoë temperatuur, hoë druk en skuifkrag, die stysel in die materiaal absorbeer water en sit uit, die kristalstruktuur word vernietig, en dit word omgeskakel in 'n amorfe toestand, wat styselgelatinisering genoem word. Styselgelatinisering kan die verteerbaarheid van troeteldierkos verbeter, want die gegelatineerde stysel is makliker om deur die verteringsensieme van troeteldiere ontbind te word. Terselfdertyd, die gegelatineerde stysel kan ook die viskositeit en bindingskrag van die materiale verbeter, maak dat die geëxtrudeerde produkte goeie vorm en tekstuur het.
Benewens styselgelatinisering, die proteïen in die materiale sal ook denaturasie ondergaan onder die werking van hoë temperatuur en hoë druk. Proteïendenaturering verwys na die verandering van die ruimtelike struktuur van proteïenmolekules sonder om die primêre struktuur te verander, wat die oplosbaarheid en verteerbaarheid van proteïen kan verbeter, en maak die troeteldierkos beter smaaklik. Terselfdertyd, die gedenatureerde proteïen kan ook 'n netwerkstruktuur vorm, wat die stysel en ander komponente kan toedraai, help om die vorm van die gepofte produk te behou.
Vierde, blaas en vorm. When the materials in the high-temperature and high-pressure state are pushed to the die head by the screw and extruded from the die hole at a high speed, the temperature and pressure of the materials drop sharply because they suddenly leave the extrusion cavity and enter the normal atmospheric environment. Under the combined action of pressure difference and temperature difference, the water in the materials evaporates rapidly, the volume of the materials expands rapidly (the expansion rate can reach 2～8 times), and the materials are dehydrated and solidified quickly to form a porous, crisp or soft puffed product.
After extrusion from the die hole, the puffed materials are cut into short particles of uniform length by the cutting device (rotary knife) installed at the die head. The length of the particles can be adjusted by changing the speed of the rotary knife to meet the requirements of different types of pet food. Byvoorbeeld, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Vyfde, post-processing. The extruded puffed particles need to go through post-processing links such as drying, verkoeling, seasoning and packaging to become the final pet food products. Drying is to reduce the water content of the particles to the standard range (10%-12% for dry products), so as to extend the shelf life of the product. Cooling is to reduce the temperature of the dried particles to room temperature, prevent the product from caking and deteriorating. Seasoning is to spray flavoring agents, attractants and other additives on the surface of the particles to improve the palatability of the product. Packaging is to pack the seasoned particles into bags or cans to ensure the hygiene and safety of the product and facilitate storage and transportation.
2.3 Key Factors Affecting Screw Extrusion Puffing Effect
The effect of screw extrusion puffing directly affects the quality of pet food. There are many factors affecting the puffing effect, hoofsaaklik grondstofeienskappe ingesluit, tempering parameters, ekstrusie parameters en die kop struktuur. Mastering these key factors and making scientific adjustments can ensure the stability of the puffing effect and the consistency of product quality.
2.3.1 Raw Material Characteristics:
The type, particle size, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. Byvoorbeeld, die styselinhoud van grondstowwe beïnvloed die uitbreidingstempo van die produk direk. Hoe hoër die styselinhoud (binne 'n sekere omvang), hoe beter die opblaas effek, en hoe groter die uitbreidingstempo van die produk. Die deeltjiegrootte van grondstowwe moet eenvormig wees, oor die algemeen 80-100 gaas. As die deeltjiegrootte te groot is, die materiaal is nie maklik om eenvormig gemeng en volledig geplastiseer te word nie, wat die blaaseffek beïnvloed; as die deeltjiegrootte te klein is, dit is maklik om materiaalblokkering te veroorsaak en energieverbruik te verhoog. Die voginhoud van grondstowwe voor tempering moet beheer word by 8%-12%. As die voginhoud te hoog is, die materiaal is maklik om aan die skroef en loop vas te hou, wat die ekstrusie en opblaas beïnvloed; as die voginhoud te laag is, the shear force and friction force between the materials are insufficient, and the starch gelatinization is incomplete, resulting in poor puffing effect.
2.3.2 Tempering Parameters:
Tempering parameters mainly include tempering temperature, tempering time and moisture content after tempering. The tempering temperature is generally 70～98℃. If the tempering temperature is too low, the materials cannot absorb water evenly, and the starch gelatinization is insufficient; if the tempering temperature is too high, the materials may be caked in advance, affecting the subsequent extrusion. The tempering time is generally 2-5 minute, which should be adjusted according to the type of raw materials and the moisture content. The moisture content after tempering is 10%～27%, which varies according to the type of pet food. Byvoorbeeld, the moisture content of dry puffed products after tempering is generally 15%-20%, while that of semi-wet products is 22%-27%.
2.3.3 Ekstrusie parameters:
Extrusion parameters are the most important factors affecting the puffing effect, hoofsaaklik skroefspoed ingesluit, ekstrusie temperatuur en ekstrusie druk. Screw speed generally ranges from 100 aan 600 rpm. Hoe hoër die skroefspoed, hoe groter die skuifkrag en wrywingskrag wat deur die materiale ontvang word, the higher the extrusion temperature and pressure, and the better the puffing effect. Egter, as die skroefspoed te hoog is, die verblyftyd van die materiaal in die ekstrusieholte is te kort, resulting in incomplete starch gelatinization and uneven mixing; as die skroefspoed te laag is, die skuifkrag en wrywingskrag is onvoldoende, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: voeding afdeling, melting section and homogenizing section. Die temperatuur van die voerafdeling is laer (70～90℃), which is mainly to prevent the materials from caking and ensure the smooth feeding; die temperatuur van die smeltgedeelte is medium (120～150℃), which is mainly to promote the melting and plasticization of the materials; the temperature of the homogenizing section is higher (150～180℃), which is mainly to ensure the uniform mixing and full gelatinization of the materials.
Extrusion pressure is generally 2～10MPa. Die druk in die ekstrusieholte word hoofsaaklik deur die kompressieverhouding van die skroef bepaal, die matrysgatgrootte en die skroefspoed. Hoe hoër die ekstrusiedruk, hoe beter die opblaas effek, but if the pressure is too high, dit sal die energieverbruik en slytasie van die toerusting verhoog; as die druk te laag is, the puffing effect is poor, and the product is loose and easy to break.
2.3.4 Die Hoofstruktuur:
Die matryskopstruktuur sluit hoofsaaklik die nommer in, vorm en grootte van die gate. The shape of the die hole determines the cross-sectional shape of the puffed product, soos omsendbrief, vierkantig, triangular and other shapes. The size of the die hole determines the initial diameter of the product. Hoe kleiner die matrysgatgrootte, hoe groter die ekstrusiedruk, and the better the puffing effect, maar die produksievermoë sal verminder word. Die aantal matrijsgate beïnvloed die produksiekapasiteit. The more the number of die holes, hoe hoër die produksievermoë, maar dit is nodig om te verseker dat die drukverspreiding eenvormig is, so as to avoid uneven puffing of the product.
3. Ons Extruders: Advantages and Product Series for Pet Food Production
Ons is lankal besig met die navorsing, development and production of food-grade extruders, and have developed a series of twin-screw extruders specially suitable for pet food production according to the characteristics of pet food processing and the needs of enterprises. Our extruders have the advantages of low operating cost, wide application range, advanced technology and reliable process control, which can meet the processing needs of various types of pet food and help enterprises improve production efficiency and product quality.
3.1 Main Advantages of Our Extruders
3.1.1 Low Lifetime Operating Cost:
We focus on the durability and economy of the equipment, and adopt high-quality materials and advanced manufacturing technology to ensure that the extruder has a long service life and low operating cost. The inner wall of the barrel is made of high-quality wear-resistant alloy steel, which has extremely strong wear resistance and can effectively resist the wear caused by the friction between the materials (especially the materials containing hard particles such as bone meal) and the barrel. This greatly extends the service life of the barrel, reducing the frequency of barrel replacement and the maintenance cost of the equipment.
Daarby, we also provide professional barrel wear measurement services. Our technical team will regularly or irregularly detect the wear of the barrel for customers, accurately judge the wear degree of the barrel, and provide professional suggestions on barrel replacement. This ensures that customers only replace the barrel when it is really needed, avoiding unnecessary waste and reducing the operating cost of the equipment. Terselfdertyd, the screw of our extruder is also made of wear-resistant alloy steel, which has good corrosion resistance and wear resistance, and can adapt to the processing of high-fat, high-protein and high-salt raw materials.
3.1.2 Wye toepassingsreeks:
Our twin-screw extruders have strong adaptability and can meet the processing needs of various types of pet food, including dry puffed products, semi-nat produkte, sagte opgeblase produkte, pet snacks and other products. The extruder is equipped with a high-torque drive system, variable screw speed and pressure variable control device, which provides excellent flexibility for customers, and can be adjusted according to different process requirements and raw material formulas to achieve the best processing effect.
The modular design of the extruder is another major feature that expands its application range. Die skroef, vat, die head and other components of the extruder adopt a modular design, which can be freely combined and replaced according to the customer’s specific application needs. Byvoorbeeld, when processing dry puffed products, customers can choose a screw with a high compression ratio and a die head with small die holes; when processing semi-wet products, they can choose a screw with a medium compression ratio and a die head with large die holes. This modular design not only improves the flexibility and adaptability of the equipment, but also reduces the cost of equipment transformation when customers adjust their product types.
3.1.3 Advanced Technology and Reliable Process Control:
Our extruders adopt the most advanced intelligent control technology, which can realize the precise control of the entire processing process, ensuring the consistency of the final product quality. The extruder is equipped with an intelligent formula memory system, which can store multiple sets of product formulas and processing parameters. When customers produce different products, hulle hoef net die ooreenstemmende formule en parameters te noem, sonder herhaalde ontfouting, which not only saves time and improves production efficiency, but also maximizes the reduction of process errors and operator errors.
The intelligent control system also has real-time monitoring and alarm functions. It can monitor key parameters such as extrusion temperature, ekstrusie druk, skroef spoed, material moisture content and production capacity in real time. If any parameter exceeds the set range, the system will issue an alarm prompt in time, and even automatically shut down the equipment if necessary, to avoid equipment failure and product quality problems. Daarby, the control system adopts a touch screen operation interface, wat eenvoudig en intuïtief is, maklik om te bedryf, and can reduce the professional requirements for operators.
3.1.4 Good Product Quality Stability:
Due to the advanced intelligent control system, uniform mixing and full plasticization of materials, the products processed by our extruders have stable quality. The particle size, vorm, hardheid, crispness and nutritional composition of the products are uniform, which can meet the strict quality requirements of pet food. Terselfdertyd, the extrusion puffing process can effectively kill harmful bacteria in the raw materials (such as Salmonella, Escherichia coli), with a sterilization rate of more than 99%, ensuring the safety of pet food and reducing the risk of pet food safety incidents.
3.1.5 Hoë produksie doeltreffendheid:
Ons dubbelskroef-ekstruders het hoë produksiedoeltreffendheid, wat baie hoër is as dié van enkelskroef-ekstruders. The production capacity of our extruders ranges from 100kg/h to 2000kg/h, wat aan die produksiebehoeftes van verskillende skale van ondernemings kan voldoen (klein, medium en groot). Die hoë-wringkrag-aandrywingstelsel en geoptimaliseerde skroefontwerp van die ekstruder kan die vervoerkapasiteit en plastiseringsdoeltreffendheid van materiale effektief verbeter, die verblyftyd van materiale in die ekstrusieholte te verminder en produksiedoeltreffendheid te verbeter. Daarby, the self-cleaning function of the twin-screw extruder can reduce the time of equipment cleaning and maintenance, further improving production efficiency.
