1. Yfirlit yfir gæludýrafóðuriðnaðinn og vinnslueinkenni
1.1 Núverandi staða og þróunarþróun gæludýrafóðuriðnaðarins
Undanfarin ár, the global pet food market has shown a steady growth trend. Driven by factors such as the increase in the number of pets, the upgrading of pet consumption concepts, and the improvement of residents’ purchasing power, the demand for high-quality, nutritious and functional pet food has continued to rise. According to relevant data statistics, the global pet food market size has exceeded 100 billion US dollars, and it is expected to maintain a growth rate of 5%-8% in the next few years. Among them, dry puffed pet food, as the most mainstream product type, accounts for more than 60% of the total pet food market, followed by wet canned products, semi-wet products and pet snacks.
The development trend of the pet food industry is mainly reflected in three aspects: first, nutrition and health. Gæludýraeigendur huga æ meira að næringarsamsetningu gæludýrafóðurs, og vörur með náttúrulegum, án aukaefna, hagnýtur (eins og hárfegurð, næringu í maga, þyngdarstjórnun) eiginleikar eru vinsælli; annað, fjölbreytni vörutegunda. Með auðgun gæludýrategunda og einstaklingsþarfir gæludýraeigenda, gæludýrafóður hefur smám saman þróast í átt að skiptingu, eins og gæludýrafóður fyrir mismunandi aldurshópa (hvolpar, fullorðnir hundar, aldraðir hundar), mismunandi tegundir, og mismunandi líkamlegar aðstæður; þriðja, greind og skilvirkni vinnslutækni. Til að mæta eftirspurn eftir framleiðslu í stórum stíl og tryggja stöðugleika vörugæða, gæludýrafóðursvinnslufyrirtæki eru stöðugt að kynna háþróaðan vinnslubúnað og snjöll stjórnkerfi til að bæta framleiðslu skilvirkni og draga úr launakostnaði.
Í ljósi þessa, extrusion puffing tækni, sem kjarnatækni í vinnslu gæludýrafóðurs (sérstaklega þurrar uppblásnar vörur), hefur orðið lykillinn að því að ákvarða gæði gæludýrafóðurs og samkeppnishæfni fyrirtækja. Faglegu extruders okkar til framleiðslu á gæludýrafóður eru þróaðar til að bregðast við einkennum iðnaðarins og eftirspurn á markaði, sem getur í raun leyst sársauka í gæludýrafóðursvinnslu og hjálpað fyrirtækjum að ná hágæða og skilvirkri framleiðslu.
1.2 Flokkun gæludýrafóðurs og vinnslueiginleika þess
Gæludýrafóður hefur margvíslegar flokkunaraðferðir, sem hægt er að skipta í mismunandi gerðir eftir vinnslutækni, vatnsinnihald, vöruform og notkun. Among them, í samræmi við vinnslutækni og vatnsinnihald, pet food is mainly divided into dry puffed products, semi-wet products, soft puffed products, wet canned products and snacks (or treats). Each type of pet food has its own unique processing characteristics and requirements for equipment, as follows:
1.2.1 Dry Puffed Products:
Dry puffed pet food is the most common type of pet food, with a water content of 10%-12%. Its main raw materials include meat meal, fish meal, cereal (corn, wheat, rice), soybean meal, vitamins, minerals and other additives. The processing process of dry puffed products is closely related to the puffing process, which requires the use of extrusion puffing equipment to process the raw materials into granular products with uniform size, crisp taste and good palatability. The characteristics of dry puffed products are long shelf life, convenient storage and transportation, and low production cost, which are suitable for large-scale production and popular among pet owners.
The key processing requirement of dry puffed products is that the raw materials need to be fully puffed, so that the starch in the raw materials is fully gelatinized, which is conducive to the digestion and absorption of pets. At the same time, the product needs to have a certain hardness and crispness to meet the chewing needs of pets and help clean their teeth. This puts high requirements on the extrusion pressure, temperature and screw speed of the extruder.
1.2.2 Semi-Wet Products:
Semi-wet pet food has a water content of 25%-35%, which is between dry and wet products. Its raw materials are similar to dry puffed products, but more humectants (such as propylene glycol, sorbitol) are added to maintain the softness and moisture of the product. The processing process of semi-wet products also needs puffing treatment, but the puffing degree is lower than that of dry products. The product has the characteristics of soft taste and good palatability, which is suitable for pets with poor chewing ability (such as elderly pets, sick pets).
The processing difficulty of semi-wet products lies in the control of water content and the prevention of product deterioration. Therefore, in the processing process, it is necessary to strictly control the temperature and humidity of each link, and select appropriate preservatives and humectants to ensure the shelf life of the product.
1.2.3 Soft Puffed Products:
Soft puffed pet food has a water content of 15%-25%, sem er vara á milli þurrblásinna og hálfblautra vara. Vinnsluferli þess er svipað og á þurrum uppblásnum vörum, en formúlan og útpressunarfæribreyturnar eru stilltar til að gera vöruna mjúka og teygjanlega. Mjúkar uppblásnar vörur sameina kosti þurrra og hálfblautra vara, með góðu bragði og auðvelda meltingu, sem hentar ýmsum gæludýrum.
1.2.4 Blautar niðursoðnar vörur:
Blautt niðursoðinn gæludýrafóður hefur meira vatnsinnihald en 70%, aðallega notað ferskt kjöt, fiskur, grænmeti og annað hráefni, sem eru unnin með matreiðslu, niðursuðu, dauðhreinsun og önnur ferli. Frábrugðið öðrum vörum, blautar niðursoðnar vörur þurfa ekki pústmeðferð, og kjarna vinnslutenglar þeirra eru eldun og dauðhreinsun. Varan hefur einkenni ríkrar næringar, sterkt bragð og hátt rakainnihald, sem hentar gæludýrum sem líkar ekki við að drekka vatn eða þurfa á viðbótarfóðrun að halda.
Lykillinn að vinnslu á blautum niðursoðnum vörum er að tryggja ferskleika og öryggi hráefna, og stranglega stjórna dauðhreinsunarhitastigi og tíma til að drepa skaðlegar bakteríur í vörunni og lengja geymsluþol. At the same time, það er nauðsynlegt að tryggja að næringarþættir vörunnar glatist ekki meðan á eldun og dauðhreinsun stendur.
1.2.5 Gæludýrasnarl (eða skemmtun):
Gæludýrasnarl er hjálparfóður fyrir gæludýr, aðallega notað til að verðlauna gæludýr, bæta skap sitt og bæta við næringu. Tegundir gæludýra snakks eru fjölbreyttar, þar á meðal uppblásið snakk, þurrkað kjötsnarl, hrikalega snakk, tannsnarl, o.s.frv. Among them, uppblásið snakk er stór hluti, 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. Til dæmis, 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 worth noting that except for canned products, most types of pet food are closely related to the puffing process. Puffing is not only the core part of pet food processing, but also directly affects the quality, taste, nutrition and digestibility of pet food. Therefore, choosing the right extrusion equipment and mastering the scientific extrusion technology are crucial for pet food processing enterprises.
2. Core Technology of Pet Food Processing: Extrusion Puffing Technology
Extrusion puffing technology is a key processing technology integrating mixing, hnoða, heating, extrusion and puffing. It has been widely used in the production of pet food due to its advantages of high production efficiency, good product quality, strong adaptability to raw materials and wide application range. In the processing of pet food, extrusion technology is mainly used to realize the puffing of raw materials, make the starch gelatinize, the protein denature, and improve the palatability and digestibility of the product. At the same time, it can also kill harmful bacteria in the raw materials, ensure the safety of pet food.
2.1 Characteristics of Pet Food Raw Materials and Requirements for Extrusion Equipment
The raw materials of pet food are mainly meat products (such as meat meal, fish meal, fresh meat), cereal, soybean meal, vitamins, minerals and other additives. Among them, meat products account for a large proportion, making the product have strong viscosity. This characteristic puts forward special requirements for extrusion equipment:
Single-screw extruders are not suitable for the economic production of pet food. Because the single-screw extruder has a narrow shear range, poor pumping capacity and no self-cleaning effect. When processing viscous materials such as meat products, it is easy to cause material accumulation, blockage and uneven mixing in the extruder barrel, which not only affects production efficiency, but also leads to unstable product quality. In addition, the single-screw extruder has high energy consumption when processing high-fat and high-protein raw materials, which increases the production cost of enterprises.
Twin-screw extruders, on the other hand, have obvious advantages in pet food production. They have a wider shear range, more effective pumping effect and self-cleaning effect, which can effectively solve the problems of material viscosity and accumulation. The twin-screw extruder can realize the uniform mixing, kneading and extrusion of materials, even when processing raw materials with high fat and fresh meat content, it can also ensure stable production and consistent product quality. Therefore, in the actual production of pet food, tvískrúfa pressuvélar eru orðnar helsta leiðin til að blása gæludýrafóður, og eru mikið notaðar við framleiðslu á þurrum puffuðum vörum, semi-wet products, mjúkar uppblásnar vörur og gæludýrasnarl.
2.2 Vinnureglur um að skrúfa útpressun
Skrúfuútdráttarferli gæludýrafóðurs er flókið eðlis- og efnafræðilegt ferli, sem felur í sér samspil margra þátta eins og hitastig, þrýstingi, klippikraftur og tími. Sértæka vinnureglan er sem hér segir:
Fyrst, formeðferð hráefnis. Duftkennd hráefni sem innihalda ákveðið magn af sterkju (meira en 20%) er blandað einsleitt í samræmi við formúluna, og síðan send í temprunartækið til temprunarmeðferðar. Tilgangurinn með temprun er að stilla rakainnihald og hitastig efnanna, so that the materials can reach the ideal state before entering the extruder. Generally, the moisture content of the materials after tempering is controlled at 10%～27%, and the temperature is raised to 70～98℃. During the tempering process, the materials absorb water evenly, which is conducive to the subsequent gelatinization of starch and denaturation of protein, and can also reduce the wear of the extruder screw and barrel.
Í öðru lagi, extrusion and heating. The tempered materials enter the screw extrusion cavity through the feeding device. The screw extrusion cavity is composed of a screw and a barrel, and the volume of the extrusion cavity gradually decreases along the axis direction. When the screw rotates, it pushes the materials forward continuously, og efnið er smám saman þjappað undir virkni skrúfunnar og tunnunnar, og þrýstingurinn í útpressunarholinu eykst smám saman. Þjöppunarhlutfallið (hlutfall rúmmáls efnisins við fóðrunarenda og rúmmáls við útpressunarenda) getur náð 4-10, sem er mismunandi eftir tegund gæludýrafóðurs og formúlu hráefna.
Meðan á því stendur að ýta og pressa út með skrúfunni, efnin verða fyrir miklum skurðarkrafti og núningskrafti. Skurkrafturinn er myndaður af hlutfallslegri hreyfingu milli skrúfunnar og tunnunnar, sem og á milli skrúfufluganna. Það getur brotið agnir efnanna, láttu hráefnin og aukefnin blandast jafnari saman, og stuðla að gelatínmyndun sterkju og eðlisbreytingu próteina. 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. In addition, according to the processing needs, steam can flow through the barrel jacket to heat the materials between the walls, so that the materials in the extrusion cavity are in a high-temperature and high-pressure state. The temperature in the extrusion cavity is generally controlled at 120～180℃, and the pressure is controlled at 2～10MPa.
Þriðja, starch gelatinization and protein denaturation. Under the action of high temperature, high pressure and shear force, the starch in the materials absorbs water and expands, the crystal structure is destroyed, and it is converted into an amorphous state, sem kallast sterkju gelatíngerð. Gelatíngerð sterkju getur bætt meltanleika gæludýrafóðurs, vegna þess að auðveldara er að brjóta niður gelatínuðu sterkjuna af meltingarensímum gæludýra. At the same time, gelatínað sterkja getur einnig bætt seigju og bindikraft efnanna, þannig að útpressuðu vörurnar hafi góða lögun og áferð.
Auk sterkju gelatínunar, próteinið í efnunum mun einnig gangast undir eðlisbreytingu undir áhrifum háhita og háþrýstings. Prótein denaturation vísar til breytinga á staðbundinni uppbyggingu próteinsameinda án þess að breyta frumbyggingu, sem getur bætt leysni og meltanleika próteina, og gera gæludýrafóðrið bragðgott. At the same time, hið eðlisbundna prótein getur líka myndað netkerfi, sem getur pakkað sterkju og öðrum hlutum, hjálpa til við að viðhalda lögun uppblásnu vörunnar.
Í fjórða lagi, púst og mótun. Þegar efni í háhita- og háþrýstingsástandi er ýtt að deyjahausnum með skrúfunni og þrýst út úr deyjaholinu á miklum hraða, hitastig og þrýstingur efnanna lækka verulega vegna þess að þau yfirgefa skyndilega útpressunarholið og fara inn í eðlilegt andrúmsloft.. Undir samsettri virkni þrýstingsmunur og hitamunur, vatnið í efnunum gufar hratt upp, rúmmál efnanna stækkar hratt (stækkunarhraði getur orðið 2-8 sinnum), og efnin eru þurrkuð og storknuð hratt til að mynda porous, stökk eða mjúk uppblásin vara.
Eftir útpressun úr deyjaholinu, 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. Til dæmis, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Fimmta, 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), so as to extend the shelf life of the product. Cooling is to reduce the temperature of the dried particles to room temperature, koma í veg fyrir að varan kex og skemmist. Krydd er að úða bragðefni, aðdráttarefni og önnur aukefni á yfirborði agna til að bæta smekkleika vörunnar. Pökkun er að pakka krydduðu agnunum í poka eða dósir til að tryggja hreinlæti og öryggi vörunnar og auðvelda geymslu og flutning.
2.3 Lykilþættir sem hafa áhrif á skrúfuútpressun Puffing áhrif
Áhrif skrúfaútpressunar hafa bein áhrif á gæði gæludýrafóðurs. Það eru margir þættir sem hafa áhrif á pústáhrifin, aðallega þar með talið eiginleika hráefnis, hitastærðir, extrusion breytur og deyja höfuð uppbyggingu. Að ná tökum á þessum lykilþáttum og gera vísindalegar breytingar getur tryggt stöðugleika blástursáhrifanna og samkvæmni vörugæða.
2.3.1 Eiginleikar hráefnis:
Týpan, kornastærð, Rakainnihald og næringarsamsetning hráefna hefur mikil áhrif á pústáhrif. Til dæmis, sterkjuinnihald hráefna hefur bein áhrif á stækkunarhraða vörunnar. Því hærra sem sterkjuinnihaldið er (innan ákveðins marks), því betri er pústáhrifin, og því meiri stækkunarhraði vörunnar. Kornastærð hráefna ætti að vera einsleit, almennt 80-100 möskva. Ef kornastærðin er of stór, Efnin eru ekki auðvelt að blanda einsleitt og plastað að fullu, sem hefur áhrif á blásandi áhrif; ef kornastærðin er of lítil, það er auðvelt að valda efnisstíflu og auka orkunotkun. Stjórna skal rakainnihaldi hráefna fyrir temprun kl 8%-12%. Ef rakainnihaldið er of hátt, efnið er auðvelt að festa við skrúfuna og tunnuna, hefur áhrif á útpressun og blástur; ef rakainnihaldið er of lágt, klippukrafturinn og núningskrafturinn á milli efnanna er ófullnægjandi, og sterkju gelatíngerðin er ófullnægjandi, sem leiðir til lélegrar blástursáhrifa.
2.3.2 Hitunarfæribreytur:
Hitunarfæribreytur innihalda aðallega hitunarhitastig, temprunartími og rakainnihald eftir temprun. Hitastigið er yfirleitt 70 ~ 98 ℃. Ef hitastigið er of lágt, efnin geta ekki tekið upp vatn jafnt, og sterkju gelatíngerðin er ófullnægjandi; ef hitastigið er of hátt, efnin má baka fyrirfram, sem hefur áhrif á síðari útpressun. Hitunartíminn er almennt 2-5 mínútur, 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. Til dæmis, 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, mainly including screw speed, extrusion temperature and extrusion pressure. Screw speed generally ranges from 100 til 600 snúningur á mínútu. The higher the screw speed, the greater the shear force and friction force received by the materials, the higher the extrusion temperature and pressure, and the better the puffing effect. Hins vegar, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete starch gelatinization and uneven mixing; if the screw speed is too low, the shear force and friction force are insufficient, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: feeding section, melting section and homogenizing section. The temperature of the feeding section is lower (70～90℃), which is mainly to prevent the materials from caking and ensure the smooth feeding; the temperature of the melting section 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.
Útpressunarþrýstingur er yfirleitt 2~10MPa. Þrýstingurinn í útpressunarholinu ræðst aðallega af þjöppunarhlutfalli skrúfunnar, stærð deyjaholunnar og skrúfuhraða. Því hærri sem útpressunarþrýstingur er, því betri er pústáhrifin, en ef þrýstingurinn er of mikill, það mun auka orkunotkun og slit búnaðarins; ef þrýstingurinn er of lágur, pústáhrifin eru léleg, og varan er laus og auðvelt að brjóta hana.
2.3.4 Deyja höfuðbygging:
Deyjahöfuðbyggingin inniheldur aðallega númerið, lögun og stærð deyjahola. Lögun deyjaholunnar ákvarðar þversniðsform blásnu vörunnar, eins og hringlaga, ferningur, þríhyrningslaga og önnur form. Stærð deyjaholunnar ákvarðar upphafsþvermál vörunnar. Því minni sem stærð deygjugatsins er, því meiri er útpressunarþrýstingurinn, and the better the puffing effect, but the production capacity will be reduced. The number of die holes affects the production capacity. The more the number of die holes, the higher the production capacity, but it is necessary to ensure that the pressure distribution is uniform, so as to avoid uneven puffing of the product.

Dry puffed pet food is the most widely used product type in the pet food industry, and our HTS BASIC series extruders are especially suitable for its production. The process flow of dry puffed pet food production using our extruders is as follows:
Raw material preparation → mixing → tempering → extrusion puffing → cutting → drying → cooling → seasoning → packaging.
4.1.1 Raw Material Preparation:
The raw materials of dry puffed pet food mainly include meat meal (chicken meal, beef meal, fish meal), cereal (corn flour, wheat flour, rice flour), soybean meal, vitamins, minerals, attractants and other additives. All raw materials need to be inspected and cleaned to remove impurities (such as stones, metals) and ensure the quality of raw materials. The raw materials are then crushed into powder with a particle size of 80-100 möskva, which is conducive to uniform mixing and full plasticization.
4.1.2 Mixing:
The crushed raw materials are sent to the mixer according to the formula ratio for uniform mixing. The mixing time is generally 5-10 mínútur, ensuring that all raw materials and additives are evenly distributed. The mixer is equipped with a weighing device, which can accurately control the dosage of each raw material, ensuring the stability of the product formula.
4.1.3 Tempering:
Blandað hráefni er sent í temprunarbúnaðinn til temprunarmeðferðar. Hitastigið er stjórnað við 80-95 ℃, temprunartíminn er 3-5 mínútur, og rakainnihaldið eftir temprun er 15%-20%. During the tempering process, gufu er sprautað inn í hitunarbúnaðinn til að láta hráefnin gleypa vatn jafnt, sem stuðlar að síðari útpressunarpúst.
4.1.4 Extrusion Puffing:
Hertu hráefnin eru send til HTS BASIC röð tveggja skrúfa extruder fyrir extrusion puffing. Skrúfuhraðanum er stjórnað kl 200-400 snúningur á mínútu, útpressunarhitastig fóðurhlutans er 70-90 ℃, bræðsluhlutinn er 130-150 ℃, og einsleitni hlutinn er 160-170 ℃. Extrusion þrýstingi er stjórnað við 5-8MPa, og þjöppunarhlutfallið er 6-8. Under the action of high temperature, high pressure and shear force, sterkjan í hráefninu er að fullu gelatínuð, próteinið er náttúrulegt, and the materials are extruded from the die head to form puffed strips.
