1. Overview of the Pet Food Industry and Processing Characteristics
1.1 Current Situation and Development Trend of the Pet Food Industry
Azken urteotan, 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. Pet owners pay more and more attention to the nutritional composition of pet food, and products with natural, additive-free, functional (such as hair beauty, stomach nourishment, weight control) characteristics are more popular; second, diversification of product types. With the enrichment of pet types and the individual needs of pet owners, pet food has gradually developed towards segmentation, such as pet food for different ages (puppies, adult dogs, elderly dogs), different breeds, and different physical conditions; third, intelligence and efficiency of processing technology. In order to meet the large-scale production demand and ensure the stability of product quality, pet food processing enterprises are constantly introducing advanced processing equipment and intelligent control systems to improve production efficiency and reduce labor costs.
Aurrekari honen aurrean, estrusio puff-teknologia, maskoten elikagaiak prozesatzeko oinarrizko teknologia gisa (bereziki puztutako produktu lehorrak), maskoten elikagaien kalitatea eta enpresen lehiakortasuna zehazteko gakoa bihurtu da. Animalientzako elikagaiak ekoizteko gure estrusore profesionalak industriaren eta merkatuaren eskariaren ezaugarriei erantzuteko garatzen dira, maskoten elikagaien prozesatzeko minak modu eraginkorrean konpondu ditzakeena eta enpresei kalitate handiko eta eraginkorra ekoizpena lortzen lagunduko diena.
1.2 Animalien Elikagaien Sailkapena eta Prozesatzeko Ezaugarriak
Animalien janariak hainbat sailkapen metodo ditu, prozesatzeko teknologiaren arabera mota ezberdinetan bana daitekeena, ur edukia, produktuaren forma eta erabilera. Among them, prozesatzeko teknologiaren eta ur edukiaren arabera, maskoten janaria puztutako produktu lehorretan banatzen da batez ere, produktu erdi-hezeak, puztutako produktu leunak, kontserba hezeak eta pintxoak (edo gozokiak). Maskoten janari mota bakoitzak bere prozesatzeko ezaugarriak eta ekipamendurako eskakizun bereziak ditu, honela:
1.2.1 Produktu puztu lehorrak:
Maskoten janari lehorra maskoten janari mota ohikoena da, ur edukiarekin 10%-12%. Bere lehengai nagusien artean haragi bazkaria dago, arrain-jana, zerealak (artoa, garia, arroza), soja-jana, bitaminak, mineralak eta beste gehigarri batzuk. Puztutako produktu lehorrak prozesatzeko prozesua puzte prozesuarekin oso lotuta dago, horrek estrusioa puff-ekipoa erabiltzea eskatzen du lehengaiak tamaina uniformeko produktu pikor batean prozesatzeko, zapore kurruskaria eta zapore ona. Puztutako produktu lehorren ezaugarriak iraupen luzea dira, biltegiratze eta garraio erosoa, eta ekoizpen kostu baxua, Eskala handiko ekoizpenerako egokiak eta maskoten jabeen artean ezagunak direnak.
Puztutako produktu lehorrak prozesatzeko baldintza nagusia lehengaiak guztiz puztuta egotea da, lehengaietako almidoia guztiz gelatinizatuta egon dadin, maskotak digestioa eta xurgatzeko lagungarria dena. Aldi berean, produktuak gogortasun eta zorroztasun jakin bat izan behar du maskoten mastekatzeko beharrak asetzeko eta hortzak garbitzeko.. Honek estrusio-presioari baldintza handiak ezartzen dizkio, estrusorearen tenperatura eta torlojuaren abiadura.
1.2.2 Produktu erdi-hezeak:
Animalientzako janari erdi hezeak ur edukia du 25%-35%, produktu lehor eta hezeen artean dagoena. Bere lehengaiak puztutako produktu lehorren antzekoak dira, baina hezetzaile gehiago (hala nola propilenglikola, sorbitola) produktuaren leuntasuna eta hezetasuna mantentzeko gehitzen dira. Produktu erdi bustiak prozesatzeko prozesuak ere puff tratamendua behar du, baina puzte-gradua produktu lehorrak baino txikiagoa da. Produktuak zapore leunaren eta zapore onaren ezaugarriak ditu, hau da, mastekatzeko gaitasun eskasa duten maskotak (hala nola, adineko maskotak, gaixorik dauden maskotak).
Produktu erdi-hezeak prozesatzeko zailtasuna ur-edukiaren kontrolan eta produktuaren hondatzea prebenitzean datza. Horregatik, prozesatzeko prozesuan, lotura bakoitzaren tenperatura eta hezetasuna zorrotz kontrolatzea beharrezkoa da, eta kontserbatzaile eta hezetzaile egokiak hautatzea produktuaren iraupena bermatzeko.
1.2.3 Puztutako produktu bigunak:
Puztu leuneko maskoten janariak ur edukia du 15%-25%, which is a product between dry puffed and semi-wet products. Its processing process is similar to that of dry puffed products, but the formula and extrusion parameters are adjusted to make the product soft and elastic. Soft puffed products combine the advantages of dry and semi-wet products, with good palatability and easy digestion, which is suitable for a variety of pets.
1.2.4 Wet Canned Products:
Wet canned pet food has a water content of more than 70%, mainly using fresh meat, fish, vegetables and other raw materials, which are processed by cooking, canning, sterilization and other processes. Different from other types of products, wet canned products do not need puffing treatment, and their core processing links are cooking and sterilization. The product has the characteristics of rich nutrition, zapore handia eta hezetasun-eduki handia, hau da, edateko ura gustatzen ez zaien edo elikadura osagarria behar duten maskotarentzat.
Kontserba hezeak prozesatzeko gakoa lehengaien freskotasuna eta segurtasuna bermatzea da, eta zorrozki kontrolatu esterilizazio tenperatura eta denbora produktuaren bakterio kaltegarriak hiltzeko eta iraupena luzatzeko. Aldi berean, beharrezkoa da produktuaren nutrizio-osagaiak ez direla galtzen sukaldaritza- eta esterilizazio-prozesuan.
1.2.5 Maskoten pintxoak (edo Opariak):
Animalien pintxoak animalientzako elikagai osagarriak dira, batez ere maskotak saritzeko erabiltzen da, beren aldartea hobetu eta elikadura osatzea. Maskoten pintxo motak askotarikoak dira, pintxo puztuak barne, haragi lehorrak pintxoak, pintxo jerky, hortzetako pintxoak, etab. Among them, puztutako pintxoak proportzio handia hartzen dute, 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. Adibidez, 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. Horregatik, 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, kneading, 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. Aldi berean, 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, arrain-jana, fresh meat), zerealak, soja-jana, bitaminak, mineralak eta beste gehigarri batzuk. 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, bestetik, 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. Horregatik, in the actual production of pet food, twin-screw extruders have become the main means of pet food puffing, and are widely used in the production of dry puffed products, produktu erdi-hezeak, soft puffed products and pet snacks.
2.2 Working Principle of Screw Extrusion Puffing
The screw extrusion puffing process of pet food is a complex physical and chemical process, eta horrek tenperatura bezalako faktore anitzen elkarrekintza dakar, presioa, ebakidura-indarra eta denbora. The specific working principle is as follows:
Lehenengoa, raw material pretreatment. The powdery raw materials containing a certain amount of starch (more than 20%) are mixed uniformly according to the formula, and then sent to the tempering device for tempering treatment. The purpose of tempering is to adjust the moisture content and temperature of the materials, estrusorean sartu aurretik materialak egoera idealera hel daitezen. Orokorrean, tenplatu ondoren materialen hezetasuna % 10 ~ % 27an kontrolatzen da, eta tenperatura 70~98 ℃-ra igotzen da. Tenplaketa prozesuan zehar, materialek ura berdin xurgatzen dute, gero almidoiaren gelatinizazioa eta proteina desnaturalizatzeko lagungarria dena, eta estrusorearen torlojuaren eta kanoiaren higadura ere murriztu dezake.
Bigarrena, estrusioa eta berokuntza. Material tenplatuak torlojuaren estrusio-barrunbean sartzen dira elikadura-gailuaren bidez. Torlojuaren estrusio-barrunbea torloju batek eta upel batek osatzen dute, eta estrusio-barrunbearen bolumena pixkanaka gutxitzen da ardatzaren norabidean. Torlojuak biratzen duenean, materialak aurrera bultzatzen ditu etengabe, and the materials are gradually compressed under the action of the screw and the barrel, and the pressure in the extrusion cavity gradually increases. The compression ratio (the ratio of the volume of the material at the feeding end to the volume at the extrusion end) can reach 4～10, 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, as well as between the screw flights. 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. Marruskadura-indarra materialen eta upelaren barruko hormaren artean sortzen da, baita material partikulen artean ere, bero asko sor dezakeena, materialak berotzeko lagungarria dena. In addition, prozesatzeko beharren arabera, lurruna upel-jakatik igaro daiteke hormen arteko materialak berotzeko, estrusio-barrunbean dauden materialak tenperatura eta presio handiko egoeran egon daitezen. Estrusio-barrunbeko tenperatura 120 ~ 180 ℃-tan kontrolatzen da., eta presioa 2~10MPa-n kontrolatzen da.
Hirugarrena, almidoiaren gelatinizazioa eta proteinen desnaturalizazioa. Tenperatura altuaren eraginpean, presio handia eta ebakidura-indarra, materialen almidoiak ura xurgatzen du eta hedatu egiten da, kristalezko egitura suntsitzen da, and it is converted into an amorphous state, which is called starch gelatinization. Starch gelatinization can improve the digestibility of pet food, because the gelatinized starch is easier to be decomposed by the digestive enzymes of pets. Aldi berean, the gelatinized starch can also improve the viscosity and binding force of the materials, making the extruded products have good shape and texture.
In addition to starch gelatinization, the protein in the materials will also undergo denaturation under the action of high temperature and high pressure. Protein denaturation refers to the change of the spatial structure of protein molecules without changing the primary structure, which can improve the solubility and digestibility of protein, and make the pet food have better palatability. Aldi berean, desnaturalizatutako proteinak sare-egitura bat ere sor dezake, almidoia eta beste osagai batzuk bil ditzakeena, puztutako produktuaren forma mantentzen lagunduz.
Laugarrena, puztu eta moldatzen. Tenperatura altuko eta presio handiko egoeran dauden materialak torlojuaren bidez trokelaren burura bultzatzen direnean eta trokelaren zulotik abiadura handian ateratzen direnean, materialen tenperatura eta presioa nabarmen jaisten dira, bat-batean estrusio-barrunbetik irten eta ingurune atmosferiko arruntean sartzen direlako.. Presio-diferentziaren eta tenperatura-diferentziaren ekintza konbinatuaren pean, materialen ura azkar lurruntzen da, materialen bolumena azkar hedatzen da (hedapen-tasa 2~8 aldiz irits daiteke), eta materialak deshidratatu eta solidotzen dira azkar porotsu bat osatzeko, puztutako produktu kurruskaria edo biguna.
Trokelaren zulotik estrusio ondoren, puztutako materialak luzera uniformeko partikula laburretan mozten ditu ebaketa-gailuak (aizto birakaria) trokelaren buruan instalatuta. Partikulen luzera egokitu daiteke labana birakariaren abiadura aldatuz, maskoten janari mota ezberdinen eskakizunak betetzeko.. Adibidez, Txakurkumeen janariaren partikulak txikiagoak eta laburragoak dira, Txakur helduentzako janariaren partikulak, berriz, handiagoak eta luzeagoak dira.
Bosgarrena, postprozesatzea. Estrusitutako puztu partikulek prozesatzeko osteko esteketatik igaro behar dute, adibidez, lehortzea, hoztea, ongailuak eta ontziratzeak maskoten elikagaien azken produktuak bihurtzeko. Lehortzea partikulen ur edukia maila estandarrera murriztea da (10%-12% produktu lehorretarako), produktuaren iraupena luzatzeko. 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, mainly including raw material characteristics, tempering parameters, extrusion parameters and die head structure. 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. Adibidez, 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, generally 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%. If the moisture content is too high, 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 minutuak, 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. Adibidez, 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 Estrusio-parametroak:
Extrusion parameters are the most important factors affecting the puffing effect, batez ere torlojuaren abiadura barne, estrusio-tenperatura eta estrusio-presioa. Screw speed generally ranges from 100 to 600 rpm. Zenbat eta handiagoa izan torlojuaren abiadura, zenbat eta handiagoa izan materialek jasotzen duten ebakidura-indarra eta marruskadura-indarra, the higher the extrusion temperature and pressure, and the better the puffing effect. Hala ere, torlojuaren abiadura handiegia bada, estrusio-barrunbean materialen egonaldi-denbora laburregia da, resulting in incomplete starch gelatinization and uneven mixing; torlojuaren abiadura baxuegia bada, ebakidura-indarra eta marruskadura-indarra nahikoak dira, and the puffing effect is poor.
Extrusion temperature is generally controlled at 120～180℃, which is divided into three sections: elikadura atala, melting section and homogenizing section. Elikadura ataleko tenperatura baxuagoa da (70～90℃), which is mainly to prevent the materials from caking and ensure the smooth feeding; urtze-atalaren tenperatura ertaina da (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. The pressure in the extrusion cavity is mainly determined by the compression ratio of the screw, the die hole size and the screw speed. The higher the extrusion pressure, the better the puffing effect, but if the pressure is too high, it will increase the energy consumption and wear of the equipment; if the pressure is too low, the puffing effect is poor, and the product is loose and easy to break.
2.3.4 Die Head Structure:
The die head structure mainly includes the number, shape and size of die holes. The shape of the die hole determines the cross-sectional shape of the puffed product, such as circular, square, triangular and other shapes. Trokelaren zuloaren tamainak produktuaren hasierako diametroa zehazten du. Zenbat eta txikiagoa izan trokelaren zuloaren tamaina, zenbat eta handiagoa izan estrusio-presioa, and the better the puffing effect, baina ekoizpen ahalmena murriztuko da. Trokelen zulo kopuruak ekoizpen ahalmenari eragiten dio. Zenbat eta gehiago trokel-zulo kopurua, zenbat eta handiagoa izan ekoizpen ahalmena, baina presio banaketa uniformea dela ziurtatu behar da, produktuaren puzketa irregularra ekiditeko.
3. Gure Extruders: Abantaila eta Produktuen Seriea Animalien Elikagaien Ekoizpenerako

The modular design of the extruder is another major feature that expands its application range. Torlojua, barrika, 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. Adibidez, when processing dry puffed products, bezeroek konpresio-erlazio handiko torlojua eta trokel-zulo txikiak dituen trokel-burua aukeratu dezakete; produktu erdi-hezeak prozesatzen direnean, konpresio-erlazio ertaineko torlojua eta trokel-zulo handiak dituen trokel-burua aukeratu dezakete. Diseinu modular honek ekipoen malgutasuna eta moldagarritasuna hobetzeaz gain, baina ekipoen eraldaketaren kostua ere murrizten du bezeroek produktu motak doitzen dituztenean.
3.1.3 Teknologia aurreratua eta prozesuen kontrol fidagarria:
Gure estrusoreek kontrol adimendunaren teknologia aurreratuena hartzen dute, prozesatzeko prozesu osoaren kontrol zehatzaz jabetu daitekeena, azken produktuaren kalitatearen koherentzia bermatuz.

Bezeroek produktu desberdinak ekoizten dituztenean, dagozkien formula eta parametroei bakarrik deitu behar diete, behin eta berriz arazketarik egin gabe, horrek denbora aurrezteaz gain produkzio-eraginkortasuna hobetzeaz gain, baina, era berean, prozesu akatsen eta operadoreen akatsen murrizketa maximizatzen du.
Kontrol sistema adimendunak denbora errealeko monitorizazio eta alarma funtzioak ere baditu. Estrusio-tenperatura bezalako funtsezko parametroak kontrola ditzake, estrusio-presioa, torlojuaren abiadura, materialaren hezetasun edukia eta ekoizpen ahalmena denbora errealean. Parametroren batek ezarritako tartea gainditzen badu, sistemak alarma-abisua emango du garaiz, eta behar izanez gero automatikoki itzali ekipoa, ekipoen hutsegite eta produktuen kalitate arazoak ekiditeko. In addition, kontrol-sistemak ukipen-pantaila funtzionatzeko interfazea hartzen du, sinplea eta intuitiboa dena, funtzionatzeko erraza, eta operadoreen eskakizun profesionalak murriztu ditzake.
3.1.4 Produktuaren Kalitate Ona Egonkortasuna:
Kontrol sistema adimendun aurreratua dela eta, nahasketa uniformea eta materialen plastifikazio osoa, gure estrusoreek prozesatutako produktuek kalitate egonkorra dute. Partikulen tamaina, forma, gogortasuna, produktuen kurruskaritasuna eta nutrizio-konposizioa uniformeak dira, maskoten elikagaien kalitate eskakizun zorrotzak bete ditzakeena. Aldi berean, Estrusioa puffing prozesuak lehengaietan bakterio kaltegarriak modu eraginkorrean hil ditzake (hala nola, Salmonella, Escherichia coli), baino gehiagoko esterilizazio-tasa batekin 99%, maskoten elikagaien segurtasuna bermatzea eta animalien elikagaien segurtasun-intzidentziaren arriskua murriztea.
3.1.5 Produkzio-eraginkortasun handia:
Gure torloju biko estrusoreek produkzio-eraginkortasun handia dute, torloju bakarreko estrusoreek baino askoz handiagoa dena. The production capacity of our extruders ranges from 100kg/h to 2000kg/h, which can meet the production needs of different scales of enterprises (small, medium and large). The high-torque drive system and optimized screw design of the extruder can effectively improve the conveying capacity and plasticization efficiency of materials, reducing the residence time of materials in the extrusion cavity and improving production efficiency. In addition, the self-cleaning function of the twin-screw extruder can reduce the time of equipment cleaning and maintenance, further improving production efficiency.
