1. Oersjoch fan 'e Pet Food Industry and Processing Characteristics
1.1 Aktuele situaasje en ûntwikkelingstrend fan 'e Pet Food Industry
Yn de lêste jierren, de wrâldwide merk foar petfood hat in konstante groeitrend toand. Oandreaun troch faktoaren lykas de taname fan it oantal húsdieren, it opwurdearjen fan konsepten foar húsdierkonsumpsje, en it ferbetterjen fan bewenners’ keapkrêft, de fraach nei hege kwaliteit, fiedend en funksjoneel húsdier iten is bleaun tanimme. Neffens relevante gegevens statistiken, de grutte fan 'e wrâldwide merk foar petfood is grutter 100 miljard Amerikaanske dollars, en it wurdt ferwachte te behâlden in groei taryf fan 5%-8% yn de kommende jierren. Under harren, droech puffed petfood, as it meast mainstream produkttype, goed foar mear as 60% fan 'e totale merk foar petfood, folge troch wiete blik produkten, semi-wiete produkten en pet snacks.
De ûntwikkelingstrend fan 'e petfood-yndustry wurdt benammen wjerspegele yn trije aspekten: earste, fieding en sûnens. Eigners fan húsdieren jouwe mear en mear omtinken foar de fiedingsgearstalling fan petfood, en produkten mei natuerlike, additieven-frij, funksjoneel (lykas hierskientme, mage fieding, gewicht kontrôle) skaaimerken binne populêrder; twadde, diversifikaasje fan produkttypen. Mei de ferriking fan húsdiertypen en de yndividuele behoeften fan húsdiereigners, petfood hat stadichoan ûntwikkele nei segmintaasje, lykas petfood foar ferskate leeftiden (puppies, folwoeksen dogs, âldere hûnen), ferskillende rassen, en ferskate fysike omstannichheden; tredde, yntelliginsje en effisjinsje fan ferwurkjen technology. Om te foldwaan oan de grutskalige produksje fraach en soargje foar de stabiliteit fan produkt kwaliteit, bedriuwen foar it ferwurkjen fan húsdieren yntrodusearje konstant avansearre ferwurkingsapparatuer en yntelliginte kontrôlesystemen om produksjeeffisjinsje te ferbetterjen en arbeidskosten te ferminderjen.
Tsjin dizze eftergrûn, extrusion puffing technology, as de kearntechnology fan it ferwurkjen fan húsdieren (benammen droege puffed produkten), is de kaai wurden foar it bepalen fan de kwaliteit fan iten foar húsdieren en it konkurrinsjefermogen fan bedriuwen. Us profesjonele extruders foar petfoodproduksje binne ûntwikkele yn reaksje op 'e skaaimerken fan' e yndustry en fraach fan 'e merk, dat kin effektyf oplosse de pine punten yn pet food ferwurkjen en helpe bedriuwen berikke hege kwaliteit en effisjinte produksje.
1.2 Klassifikaasje fan Pet Food en syn ferwurkjen skaaimerken
Pet iten hat in ferskaat oan klassifikaasje metoaden, dy't kinne wurde ferdield yn ferskate soarten neffens ferwurkingstechnology, wetter ynhâld, produkt foarm en gebrûk. Under harren, neffens de ferwurkingstechnology en wetterynhâld, petfood is benammen ferdield yn droege puffed produkten, semi-wet produkten, sêfte puffed produkten, wiete blik produkten en snacks (of treats). Elk type petfood hat syn eigen unike ferwurkingseigenskippen en easken foar apparatuer, as folget:
1.2.1 Droege puffed produkten:
Drye puffed petfood is it meast foarkommende type petfood, mei in wetter ynhâld fan 10%-12%. Syn wichtichste grûnstoffen omfetsje fleismiel, fisk miel, cereal (nôt, weet, rys), soybean meal, vitaminen, mineralen en oare additieven. It ferwurkingsproses fan droege puffed produkten is nau besibbe oan it puffing proses, dat fereasket it brûken fan extrusion puffing apparatuer te ferwurkjen de grûnstoffen yn korrelige produkten mei unifoarm grutte, skerpe smaak en goede smaak. De skaaimerken fan droege puffed produkten binne lange planke libben, handige opslach en ferfier, en lege produksjekosten, dy't geskikt binne foar grutskalige produksje en populêr ûnder húsdiereigners.
De kaai ferwurkingseask fan droege puffed produkten is dat de grûnstoffen moatte wurde folslein puffed, sadat it setmoal yn 'e grûnstoffen folslein gelatinisearre is, dat is befoarderlik foar de spiisfertarring en opname fan húsdieren. Tagelyk, it produkt moat in bepaalde hurdens en crispness hawwe om te foldwaan oan 'e kauwenbehoeften fan húsdieren en helpe har tosken skjin te meitsjen. Dit stelt hege easken oan de extrusion druk, temperatuer en skroef snelheid fan de extruder.
1.2.2 Semi-wet produkten:
Semi-wet pet food hat in wetter ynhâld fan 25%-35%, dat is tusken droege en wiete produkten. De grûnstoffen binne fergelykber mei droege puffed produkten, mar mear humectants (lykas propylene glycol, sorbitol) wurde tafoege om de sêftens en fochtigens fan it produkt te behâlden. It ferwurkjen proses fan semi-wiete produkten hat ek nedich puffing behanneling, mar de puffing graad is leger as dy fan droege produkten. It produkt hat de skaaimerken fan sêfte smaak en goede smaak, dy't geskikt is foar húsdieren mei min kauwfeardigens (lykas âldere húsdieren, sike húsdieren).
De swierrichheid by it ferwurkjen fan semi-wiete produkten leit yn 'e kontrôle fan wetterynhâld en it foarkommen fan produktferfal. Dêrom, yn it ferwurkingsproses, it is needsaaklik om de temperatuer en fochtigens fan elke keppeling strikt te kontrolearjen, en selektearje passende conserveringsmiddelen en humectants om te garandearjen de houdbaarheid fan it produkt.
1.2.3 Soft Puffed Products:
Soft puffed pet food hat in wetter ynhâld fan 15%-25%, dat is in produkt tusken droege puffed en semi-wiete produkten. It ferwurkingsproses is fergelykber mei dat fan droege puffed produkten, mar de formule en extrusion parameters wurde oanpast om it produkt sêft en elastysk. Soft puffed produkten kombinearje de foardielen fan droege en semi-wiete produkten, mei goede smaak en maklik spiisfertarring, dat is geskikt foar in ferskaat oan húsdieren.
1.2.4 Wet Canned Products:
Wiet blik pet food hat in wetter ynhâld fan mear as 70%, benammen mei farsk fleis, fisk, grienten en oare grûnstoffen, dy't wurde ferwurke troch koken, blik, sterilisaasje en oare prosessen. Oars as oare soarten produkten, wiete blik produkten net nedich puffing behanneling, en har kearnferwurkingslinks binne koken en sterilisaasje. It produkt hat de skaaimerken fan rike fieding, sterke smaak en hege vocht ynhâld, dy't geskikt is foar húsdieren dy't net fan drinkwetter hâlde of oanfoljende fieding nedich binne.
De kaai foar it ferwurkjen fan wiete blikprodukten is om de frisheid en feiligens fan grûnstoffen te garandearjen, en strikt kontrolearje de sterilisaasje temperatuer en tiid te deadzjen skealike baktearjes yn it produkt en ferlingje de planke libben. Tagelyk, It is needsaaklik om te soargjen dat de fiedingskomponinten fan it produkt net ferlern gean tidens it koken en sterilisaasjeproses.
1.2.5 Pet Snacks (of Treats):
Petsnacks binne helpfet foar húsdieren, benammen brûkt om húsdieren te beleanjen, ferbetterje harren stimming en supplement fieding. The types of pet snacks are diverse, including puffed snacks, dried meat snacks, jerky snacks, dental snacks, ensfh. Under harren, puffed snacks account for a large proportion, and their processing process is similar to dry puffed products, but the formula is more refined, and more flavoring agents and functional additives are added to meet the taste and functional needs of pets.
Pet snacks have high requirements for taste, appearance and functionality. Bygelyks, dental snacks need to have a certain hardness and texture to help clean the pet’s teeth and prevent dental calculus; hair-beautifying snacks need to add ingredients such as lecithin to help improve the pet’s hair quality. This requires the extruder to have good flexibility and adjustability to meet the processing needs of different types of snacks.
It is de muoite wurdich opskriuwen dat útsein foar blik produkten, de measte soarten petfood binne nau besibbe oan it puffingproses. Puffing is net allinich it kearndiel fan it ferwurkjen fan húsdieren, mar ek direkt ynfloed op de kwaliteit, smaak, fieding en digestibility fan pet food. Dêrom, it kiezen fan de juste extrusion-apparatuer en it behearskjen fan 'e wittenskiplike extrusiontechnology binne krúsjaal foar bedriuwen foar ferwurkjen fan húsdieren.
2. Core Technology fan Pet Food Processing: Extrusion Puffing Technology
Extrusion puffing technology is in wichtige ferwurkingstechnology dy't mingen yntegrearret, kneading, ferwaarming, extrusion en puffing. It is in protte brûkt yn 'e produksje fan petfood fanwegen syn foardielen fan hege produksje-effisjinsje, goede produkt kwaliteit, sterke oanpassingsfermogen oan grûnstoffen en breed applikaasje berik. By it ferwurkjen fan petfood, extrusion technology wurdt benammen brûkt om te realisearjen it puffing fan grûnstoffen, meitsje it setmoal gelatinisearje, de proteïne denaturaasje, en ferbetterje de smaak en digestibility fan it produkt. Tagelyk, it kin ek skealike baktearjes yn 'e grûnstoffen deadzje, soargje foar de feiligens fan petfood.
2.1 Skaaimerken fan Pet Food Raw Materialen en easken foar extrusion Equipment
De grûnstoffen fan petfood binne benammen fleisprodukten (lykas fleismiel, fisk miel, farsk fleis), cereal, soybean meal, vitaminen, mineralen en oare additieven. Under harren, fleisprodukten meitsje in grut part út, wêrtroch it produkt in sterke viskositeit hat. Dit karakteristyk stelt spesjale easken foar extrusion apparatuer:
Single-screw extruders binne net geskikt foar de ekonomyske produksje fan pet food. Omdat de single-screw extruder hat in smel shear berik, minne pompkapasiteit en gjin selsreinigjende effekt. By it ferwurkjen fan taaie materialen lykas fleisprodukten, it is maklik om materiaal accumulation te feroarsaakjen, blokkade en oneffen mingen yn de extruder barrel, dy't net allinnich ynfloed op produksje effisjinsje, mar ek liedt ta instabyl produkt kwaliteit. Derneist, de single-screw extruder hat hege enerzjyferbrûk by it ferwurkjen fan hege fet en hege proteïne grûnstoffen, wat de produksjekosten fan bedriuwen fergruttet.
Twin-screw extruders, oan de oare kant, hawwe foar de hân lizzende foardielen yn petfood produksje. Se hawwe in breder shear berik, effektiver pompeffekt en selsreinigjende effekt, dat kin effektyf oplosse de problemen fan materiaal viscosity en accumulation. De twin-screw extruder kin realisearje it unifoarm mingen, kneading en extrusion fan materialen, sels by it ferwurkjen fan grûnstoffen mei hege fet en farsk fleis ynhâld, it kin ek soargje foar stabile produksje en konsekwint produkt kwaliteit. Dêrom, yn 'e eigentlike produksje fan petfood, twin-screw extruders binne wurden de wichtichste middel fan puffing húsdier iten, en wurde in protte brûkt yn 'e produksje fan droege puffed produkten, semi-wet produkten, sêfte puffed produkten en pet snacks.
2.2 Wurkprinsipe fan Screw Extrusion Puffing
It puffingproses fan skroefekstrudering fan petfood is in kompleks fysyk en gemysk proses, dy't de ynteraksje fan meardere faktoaren omfettet, lykas temperatuer, druk, skuorkrêft en tiid. It spesifike wurkprinsipe is as folget:
Earste, grûnstof foarbehanneling. De poederige grûnstoffen dy't in bepaalde hoemannichte setmoal befetsje (mear as 20%) wurde unifoarm mingd neffens de formule, en dan stjoerd nei de tempering apparaat foar tempering behanneling. It doel fan tempering is om de fochtynhâld en temperatuer fan 'e materialen oan te passen, sadat de materialen de ideale steat kinne berikke foardat se de extruder yngeane. Meastal, de fochtynhâld fan 'e materialen nei tempering wurdt regele op 10% ~ 27%, en de temperatuer wurdt ferhege nei 70 ~ 98 ℃. Tidens it tempering proses, de materialen absorbearje wetter gelijkmatig, wat befoarderlik is foar de folgjende gelatinisaasje fan setmoal en denaturaasje fan proteïne, en kin ek ferminderjen de wear fan de extruder skroef en barrel.
Twadde, extrusion en ferwaarming. De temperearre materialen komme yn 'e skroef-ekstrusjeholte troch it fiedingsapparaat. De skroef extrusion holte is gearstald út in skroef en in barrel, en it folume fan de extrusion holte stadichoan nimt ôf lâns de as rjochting. As de skroef draait, it triuwt de materialen kontinu foarút, en de materialen wurde stadichoan komprimearre ûnder de aksje fan 'e skroef en it barrel, en de druk yn 'e extrusion holte stadichoan nimt ta. De kompresje ratio (de ferhâlding fan it folume fan it materiaal oan de feeding ein oan it folume oan de extrusion ein) kin berikke 4-10, dy't fariearret neffens it type pet iten en de formule fan grûnstoffen.
Tidens it proses fan triuwe en extruded troch de skroef, de materialen wurde ûnderwurpen oan sterke skuorkrêft en wriuwingskrêft. De skuorkrêft wurdt generearre troch de relative beweging tusken de skroef en de loop, likegoed as tusken de skroef flechten. It kin de dieltsjes fan 'e materialen brekke, meitsje de grûnstoffen en tafoegings mix mear uniform, en befoarderje de gelatinisaasje fan setmoal en denaturaasje fan protein. De wriuwingskrêft wurdt generearre tusken de materialen en de binnenmuorre fan 'e loop, likegoed as tusken de materiaal dieltsjes, dat kin generearje in soad waarmte, wat befoarderlik is foar de ferwaarming fan de materialen. Derneist, neffens de ferwurkingsbehoeften, stoom kin streame troch de barrel jas te ferwaarmjen de materialen tusken de muorren, sadat de materialen yn 'e extrusion holte binne yn in hege temperatuer en hege druk steat. De temperatuer yn 'e extrusion holte wurdt algemien regele op 120 ~ 180 ℃, en de druk wurdt regele op 2 ~ 10MPa.
Tredde, setmoal gelatinization en protein denaturation. Under de aksje fan hege temperatueren, hege druk en skuorkrêft, it setmoal yn 'e materialen nimt wetter op en wreidet út, de kristalstruktuer wurdt ferneatige, en it wurdt omboud ta in amorfe steat, dat hjit zetmeel gelatinization. Zetmeel gelatinization kin ferbetterje digestibility fan pet food, om't it gelatinisearre setmoal makliker wurdt ôfbrutsen troch de digestive enzymen fan húsdieren. Tagelyk, it gelatinisearre setmoal kin ek de viskositeit en bindende krêft fan 'e materialen ferbetterje, wêrtroch't de ekstrudearre produkten in goede foarm en tekstuer hawwe.
Neist setmoal gelatinization, it aaiwyt yn 'e materialen sil ek denaturaasje ûndergean ûnder de aksje fan hege temperatuer en hege druk. Proteindenaturaasje ferwiist nei de feroaring fan 'e romtlike struktuer fan proteinmolekulen sûnder de primêre struktuer te feroarjen, which can improve the solubility and digestibility of protein, and make the pet food have better palatability. Tagelyk, the denatured protein can also form a network structure, which can wrap the starch and other components, helping to maintain the shape of the puffed product.
Fjirde, puffing and shaping. 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. Bygelyks, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Fyfde, post-processing. The extruded puffed particles need to go through post-processing links such as drying, cooling, 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), om de houdbaarheid fan it produkt te ferlingjen. Koeling is om de temperatuer fan 'e droege dieltsjes te ferleegjen nei keamertemperatuer, foarkomme dat it produkt koekt en fergriemt. Seasoning is om smaakstoffen te spuiten, attraksjes en oare tafoegings op it oerflak fan 'e dieltsjes om de smaak fan it produkt te ferbetterjen. Ferpakking is om de betûfte dieltsjes yn sekken of blikjes te pakken om de hygiëne en feiligens fan it produkt te garandearjen en opslach en ferfier te fasilitearjen.
2.3 Key faktoaren dy't beynfloedzje Screw Extrusion Puffing Effect
It effekt fan puffing fan skroef-ekstrusje hat direkt ynfloed op de kwaliteit fan petfood. D'r binne in protte faktoaren dy't it puffende effekt beynfloedzje, benammen ynklusyf grûnstof eigenskippen, tempering parameters, extrusion parameters en die kop struktuer. 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 Materiaal Skaaimerken:
It type, partikel grutte, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. Bygelyks, the starch content of raw materials directly affects the expansion rate of the product. The higher the starch content (within a certain range), the better the puffing effect, and the larger the expansion rate of the product. The particle size of raw materials should be uniform, meastal 80-100 mesh. If the particle size is too large, the materials are not easy to be mixed uniformly and plasticized fully, which affects the puffing effect; if the particle size is too small, it is easy to cause material blockage and increase energy consumption. The moisture content of raw materials before tempering should be controlled at 8%-12%. As it fochtgehalte te heech is, the materials are easy to stick to the screw and barrel, affecting the extrusion and puffing; if the moisture content is too low, 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 minuten, 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. Bygelyks, 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 Extrusion Parameters:
Extrusion parameters are the most important factors affecting the puffing effect, benammen ynklusyf screw snelheid, extrusion temperatuer en extrusion druk. Screw speed generally ranges from 100 nei 600 rpm. Hoe heger de skroef snelheid, hoe grutter de skuorkrêft en wriuwingskrêft ûntfongen troch de materialen, the higher the extrusion temperature and pressure, and the better the puffing effect. Lykwols, as de skroef snelheid is te heech, de ferbliuwstiid fan de materialen yn de extrusion holte is te koart, resulting in incomplete starch gelatinization and uneven mixing; as de skroef snelheid is te leech, de skuorkrêft en wriuwingskrêft binne net genôch, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: feeding seksje, melting section and homogenizing section. De temperatuer fan 'e feeding seksje is leger (70～90℃), which is mainly to prevent the materials from caking and ensure the smooth feeding; de temperatuer fan 'e smeltende seksje 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. De druk yn 'e extrusionholte wurdt benammen bepaald troch de kompresjeferhâlding fan' e skroef, de gat grutte en de skroef snelheid. Hoe heger de extrusion druk, the better the puffing effect, but if the pressure is too high, it sil it enerzjyferbrûk en wear fan 'e apparatuer ferheegje; as de druk te leech is, the puffing effect is poor, and the product is loose and easy to break.
2.3.4 Die Head Struktuer:
De diekopstruktuer omfettet benammen it nûmer, foarm en grutte fan die gatten. The shape of the die hole determines the cross-sectional shape of the puffed product, lykas circular, plein, triangular and other shapes. The size of the die hole determines the initial diameter of the product. De lytser de grutte fan it die gat, wat grutter de extrusion druk, and the better the puffing effect, mar de produksjekapasiteit sil wurde fermindere. It oantal die gatten beynfloedet de produksje kapasiteit. The more the number of die holes, wat heger de produksjekapasiteit, mar it is nedich om te soargjen dat de druk ferdieling is unifoarm, so as to avoid uneven puffing of the product.
