1. Sealladh farsaing air Gnìomhachas Bidhe Peataichean agus Feartan Giullachd
1.1 An suidheachadh làithreach agus gluasad leasachaidh gnìomhachas bìdh peata
Anns na bliadhnachan mu dheireadh, 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.
An aghaidh a' chùl-fhiosrachaidh seo, teicneòlas puffing eas-tharraing, mar phrìomh theicneòlas giollachd bìdh peata (gu sònraichte toraidhean puffed tioram), air a thighinn gu bhith na phrìomh dhòigh ann a bhith a’ dearbhadh càileachd biadh peata agus farpaiseachd iomairtean. Tha na extruders proifeasanta againn airson cinneasachadh biadh peata air an leasachadh mar fhreagairt air feartan a’ ghnìomhachais agus iarrtas margaidh, a dh’ fhaodas na puingean pian ann an giullachd bìdh peata fhuasgladh gu h-èifeachdach agus iomairtean a chuideachadh gus cinneasachadh àrd-inbhe agus èifeachdach a choileanadh.
1.2 Seòrsachadh biadh peata agus na feartan giullachd aige
Tha grunn dhòighean seòrsachaidh aig biadh peata, a dh'fhaodar a roinn ann an diofar sheòrsaichean a rèir teicneòlas giollachd, susbaint uisge, cruth toraidh agus cleachdadh. Among them, a rèir teicneòlas giollachd agus susbaint uisge, tha biadh peata air a roinn sa mhòr-chuid ann am bathar puffed tioram, bathar leth-fhliuch, bathar bog puffed, toraidhean canasta fliuch agus greimean-bìdh (no a’ làimhseachadh). Tha na feartan giullachd sònraichte fhèin aig gach seòrsa de bhiadh peata agus riatanasan airson uidheamachd, mar a leanas:
1.2.1 Toraidhean puffed tioram:
Is e biadh peata puffed tioram an seòrsa de bhiadh peata as cumanta, le cion uisge 10%-12%. Am measg nam prìomh stuthan amh tha biadh feòil, biadh èisg, arbhair (arbhar, cruithneachd, reis), biadh pòna soighe, vitamain, mèinnirean agus stuthan cur-ris eile. Tha dlùth cheangal aig pròiseas giollachd thoraidhean puffed tioram ris a’ phròiseas puffing, a dh’ fheumas uidheamachd puffing eas-tharraing a chleachdadh gus na stuthan amh a phròiseasadh gu toraidhean gràineach le meud èideadh, blas crisp agus blas math. Is e feartan thoraidhean puffed tioram beatha sgeilp fada, stòradh agus còmhdhail goireasach, 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) air an cur ris gus bog agus taiseachd an toraidh a chumail suas. Feumaidh pròiseas giollachd thoraidhean leth-fhliuch cuideachd làimhseachadh puffing, ach tha an ìre puffaidh nas ìsle na ìre thoraidhean tioram. Tha feartan blas bog agus blas math aig an toradh, a tha freagarrach dha peataichean le droch chomas cagnaidh (leithid peataichean nas sine, peataichean tinn).
Tha duilgheadas giollachd thoraidhean leth-fhliuch na laighe ann a bhith a’ cumail smachd air susbaint uisge agus casg air crìonadh toraidh. Uime sin, anns a 'phròiseas giollachd, feumar smachd teann a chumail air teòthachd agus taiseachd gach ceangail, agus tagh stuthan-gleidhidh agus humectants iomchaidh gus dèanamh cinnteach à beatha sgeilp an toraidh.
1.2.3 Bathar bog puffed:
Tha susbaint uisge aig biadh peata bog puffed 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, strong palatability and high moisture content, which is suitable for pets who do not like drinking water or need supplementary nutrition.
The key to the processing of wet canned products is to ensure the freshness and safety of raw materials, and strictly control the sterilization temperature and time to kill harmful bacteria in the product and extend the shelf life. At the same time, it is necessary to ensure that the nutritional components of the product are not lost during the cooking and sterilization process.
1.2.5 Pet Snacks (or Treats):
Pet snacks are auxiliary food for pets, mainly used to reward pets, improve their mood and supplement nutrition. The types of pet snacks are diverse, including puffed snacks, dried meat snacks, jerky snacks, dental snacks, etc. Among them, 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. Mar eisimpleir, 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. Chan eil puffing a-mhàin na phrìomh phàirt de ghiollachd bìdh pheataichean, ach cuideachd buaidh dhìreach air càileachd, blasad, beathachadh agus cnàmhadh biadh peata. Uime sin, tha a bhith a’ taghadh an uidheamachd eas-tharraing ceart agus a’ faighinn maighstireachd air an teicneòlas eas-tharraing saidheansail deatamach airson iomairtean giollachd bìdh peata.
2. Prìomh theicneòlas giollachd bìdh peata: Teicneòlas puffing eas-tharraing
Tha teicneòlas puffing eas-tharraing na phrìomh theicneòlas giullachd a tha ag amalachadh measgachadh, a' gluineachadh, teasachadh, eas-tharraing agus puffing. Tha e air a bhith air a chleachdadh gu bitheanta ann an dèanamh peata biadh air sgàth na buannachdan àrd cinneasachadh èifeachdas, càileachd toraidh math, sùbailteachd làidir a thaobh stuthan amh agus raon tagraidh farsaing. Ann a bhith a 'giollachd biadh peataichean, Tha teicneòlas eas-tharraing air a chleachdadh sa mhòr-chuid gus puffing stuthan amh a thoirt gu buil, dèan an stalc gelatinize, an nàdar pròtain, agus ag adhartachadh blasad agus cnàmhadh an toraidh. At the same time, faodaidh e cuideachd bacteria cronail a mharbhadh anns na stuthan amh, dèanamh cinnteach à sàbhailteachd biadh peataichean.
2.1 Feartan stuthan amh Biadh Peataichean agus riatanasan airson uidheamachd eas-tharraing
Is e stuthan feòil a th’ ann an stuthan amh biadh peata sa mhòr-chuid (leithid biadh feòil, biadh èisg, feòil ùr), arbhair, biadh pòna soighe, vitamain, mèinnirean agus stuthan cur-ris eile. Among them, tha toraidhean feòla a’ toirt cunntas air cuibhreann mòr, dèanamh cinnteach gu bheil slaodachd làidir aig an toradh. Tha am feart seo a’ cur air adhart riatanasan sònraichte airson uidheamachd eas-tharraing:
Chan eil extruders aon-sgriubha freagarrach airson cinneasachadh eaconamach biadh peata. Leis gu bheil raon rùsgaidh cumhang aig an extruder aon-sgriubha, droch chomas pumpaidh agus gun bhuaidh fèin-ghlanadh. Nuair a bhios tu a 'giollachd stuthan slaodach leithid stuthan feòla, tha e furasta a bhith ag adhbhrachadh cruinneachadh stuthan, bacadh agus measgachadh neo-chòmhnard anns a’ bharaille extruder, 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. Uime sin, 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, bathar leth-fhliuch, 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, which involves the interaction of multiple factors such as temperature, cuideam, shear force and time. The specific working principle is as follows:
A’ chiad, 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, so that the materials can reach the ideal state before entering the extruder. Anns an fharsaingeachd, 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.
An dàrna, 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, agus tha na stuthan air an teannachadh mean air mhean fo ghnìomhachd an sgriubha agus a’ bharaille, agus bidh an cuideam anns a’ chuas eas-tharraing ag àrdachadh mean air mhean. An co-mheas teannachaidh (an co-mheas eadar meud an stuth aig a’ cheann beathachaidh agus an tomhas-lìonaidh aig a’ cheann eas-tharraing) faodaidh e ruighinn 4 ~ 10, a tha ag atharrachadh a rèir an seòrsa biadh peata agus foirmle stuthan amh.
Rè a 'phròiseas a bhith air a phutadh agus extruded leis an sgriubha, tha na stuthan fo smachd feachd rùsgaidh làidir agus feachd brisidh. Tha an fheachd rùsgaidh air a chruthachadh leis a’ ghluasad dàimheach eadar an sgriubha agus am baraille, a bharrachd air eadar na tursan-adhair sgriubha. Faodaidh e na mìrean de na stuthan a bhriseadh, dèan na stuthan amh agus na stuthan cur-ris a’ measgachadh nas èideadh, agus adhartachadh gelatinization de stalc agus dì-nàdarachadh pròtain. 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.
An treas, 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, 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. At the same time, 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. At the same time, 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.
An ceathramh, 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. Mar eisimpleir, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
An còigeamh, post-processing. The extruded puffed particles need to go through post-processing links such as drying, fuarachadh, 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, casg a chur air an toradh bho bhith a 'còcaireachd agus a' crìonadh. Is e seusanachadh a bhith a’ frasadh riochdairean blasaidh, luchd-tarraing agus stuthan cur-ris eile air uachdar nam mìrean gus blasad an toraidh a leasachadh. Is e pacadh na mìrean ràitheil a phacadh ann am pocannan no canaichean gus dèanamh cinnteach à slàinteachas agus sàbhailteachd an toraidh agus gus stòradh agus còmhdhail a dhèanamh comasach..
2.3 Prìomh fhactaran a bheir buaidh air buaidh puffing extrusion sgriubha
Bidh buaidh puffing extrusion sgriubha a’ toirt buaidh dhìreach air càileachd biadh peata. Tha grunn nithean ann a tha a’ toirt buaidh air a’ bhuaidh puffing, sa mhòr-chuid a’ toirt a-steach feartan stuthan amh, crìochan teòthachd, crìochan eas-tharraing agus structar ceann bàs. Le bhith a’ maighstireachd nam prìomh nithean sin agus a’ dèanamh atharrachaidhean saidheansail faodaidh sin dèanamh cinnteach à seasmhachd buaidh puffing agus cunbhalachd càileachd toraidh.
2.3.1 Feartan stuthan amh:
An seòrsa, meud gràin, tha susbaint taiseachd agus co-dhèanamh beathachaidh stuthan amh a’ toirt buaidh mhòr air a ’bhuaidh puffing. Mar eisimpleir, bidh susbaint stalc stuthan amh a’ toirt buaidh dhìreach air ìre leudachaidh an toraidh. Mar as àirde an susbaint stalc (taobh a-staigh raon sònraichte), is ann as fheàrr a’ bhuaidh puffing, agus mar as motha an ìre leudachaidh den toradh. Bu chòir meud nan stuthan amh a bhith co-ionnan, san fharsaingeachd 80-100 mogal. Ma tha meud na gràin ro mhòr, chan eil na stuthan furasta a mheasgachadh gu co-ionnan agus air an làn phlastaig, a bheir buaidh air a’ bhuaidh puffing; ma tha meud na gràin ro bheag, tha e furasta bacadh stuthan adhbhrachadh agus caitheamh lùtha àrdachadh. Bu chòir smachd a chumail air susbaint taiseachd stuthan amh mus tèid an teannachadh aig 8%-12%. Ma tha an taiseachd ro àrd, 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 mionaidean, 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. Mar eisimpleir, 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 gu 600 rpm. 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. Ge-tà, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, mar thoradh air gelatinization stalc neo-choileanta agus measgachadh neo-chòmhnard; ma tha astar an sgriubha ro ìosal, chan eil an fheachd rùsgaidh agus an fheachd brisidh gu leòr, agus tha a’ bhuaidh puffaidh truagh.
Mar as trice bidh teòthachd eas-tharraing air a smachdachadh aig 120 ~ 180 ℃, a tha air a roinn na thrì earrannan: roinn beathachaidh, earrann leaghaidh agus earrann homogenizing. Tha teòthachd an earrann beathachaidh nas ìsle (70～ 90 ℃), a tha sa mhòr-chuid airson casg a chuir air na stuthan bho bhith a’ còcaireachd agus dèanamh cinnteach à biadhadh rèidh; tha teòthachd na h-earrainn leaghaidh meadhanach (120～ 150 ℃), a tha gu sònraichte airson a bhith a’ brosnachadh leaghadh agus plastadh nan stuthan; tha teòthachd na h-earrainn homogenizing nas àirde (150～ 180 ℃), a tha gu ìre mhòr airson dèanamh cinnteach à measgachadh èideadh agus làn gelatinization de na stuthan.
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, is ann as fheàrr a’ bhuaidh puffing, 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. The size of the die hole determines the initial diameter of the product. The smaller the die hole size, the greater the extrusion pressure, 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.

3.1 Prìomh Bhuannachdan ar Extruders
3.1.1 Cosgais Obrachaidh Fad-beatha Ìosal:
Bidh sinn a’ cuimseachadh air seasmhachd agus eaconamaidh an uidheamachd, agus gabhail ri stuthan àrd-inbhe agus teicneòlas saothrachaidh adhartach gus dèanamh cinnteach gu bheil beatha seirbheis fhada aig an extruder agus cosgais obrachaidh ìosal. Tha balla a-staigh a’ bharaille air a dhèanamh de stàilinn alloy àrd-inbhe a tha an aghaidh caitheamh, aig a bheil neart caitheamh làidir agus is urrainn gu h-èifeachdach seasamh an aghaidh a’ chaitheamh a dh’ adhbhraicheas an suathadh eadar na stuthan (gu h-àraidh na stuthan anns a bheil mìrean cruaidh leithid min-chnàimh) agus am baraille. Tha seo gu mòr a 'leudachadh beatha seirbheis a' bharaille, lùghdachadh tricead ath-chur baraille agus cosgais cumail suas an uidheim.
In addition, bidh sinn cuideachd a’ toirt seachad seirbheisean tomhais caitheamh baraille proifeasanta. Lorgaidh an sgioba teignigeach againn gu cunbhalach no gu neo-riaghailteach caitheamh a’ bharaille airson luchd-ceannach, breithneachadh ceart air ìre caitheamh a’ bharaille, agus molaidhean proifeiseanta a thoirt seachad mu ath-chur baraille. Bidh seo a’ dèanamh cinnteach nach cuir luchd-ceannach an àite a’ bharaille ach nuair a tha fìor fheum air, a’ seachnadh sgudal neo-riatanach agus a’ lughdachadh cosgais obrachaidh an uidheim. At the same time, tha an sgriubha den extruder againn cuideachd air a dhèanamh de stàilinn alloy a tha an aghaidh caitheamh, aig a bheil deagh sheasamh an aghaidh creimeadh agus caitheamh caitheamh, agus is urrainn dhaibh gabhail ri giullachd geir àrd, stuthan amh àrd-phròtain agus àrd-salainn.
3.1.2 Raon tagraidh farsaing:
Our twin-screw extruders have strong adaptability and can meet the processing needs of various types of pet food, including dry puffed products, bathar leth-fhliuch, bathar bog puffed, 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. The screw, baraille, 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. Mar eisimpleir, 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, they only need to call the corresponding formula and parameters, without repeated debugging, 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, extrusion pressure, astar sgriubha, 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. In addition, the control system adopts a touch screen operation interface, which is simple and intuitive, easy to operate, 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, cumadh, cruas, crispness and nutritional composition of the products are uniform, which can meet the strict quality requirements of pet food. At the same time, 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 High Production Efficiency:
