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%, 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.

Extrusion puffing technology is a key processing technology integrating mixing, kneading, k'íintik, 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, harina kayo'ob, fresh meat), sereal, soybean meal, vitamins, minerals and other additives. ichil leti'obe', le yik'áalil bak'o' ku beetiko'ob jump'éel nojoch jaats, beetik u le producto yaan ti' jump'éel k'a'am viscosidad.

Extrusoras u ka'ap'éel tornillos, tu láak' tséel, 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, twin-screw extruders have become the main means of pet food puffing, and are widely used in the production of dry puffed products, yik'áalil semi-húmedos, 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, presion, shear force and time. The specific working principle is as follows:
Yáaxil, 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. 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, ba'ax ku yáantaj ti' le gelatinización posterior ti' le almidón yéetel le desnaturalización ti' le proteína, yéetel xan je'el u páajtal u xu'ulsiko'ob u desgaste le tornillo extrusora yéetel le barril.

Le relación compresión (le relación ichil u volumen le xooko'obo' ti' le extremo alimentación ti' le volumen ti' le extremo extrusión) je'el u k'uchul 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. 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.

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. jéel bix, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Fifth, post-processing. The extruded puffed particles need to go through post-processing links such as drying, síis, seasoning and packaging to become the final pet food products. Drying is to reduce the water content of the particles to the standard range (10%-12% for dry products), so as to extend the shelf life of the product. Cooling is to reduce the temperature of the dried particles to room temperature, prevent the product from caking and deteriorating. Seasoning is to spray flavoring agents, attractants and other additives on the surface of the particles to improve the palatability of the product. Packaging is to pack the seasoned particles into bags or cans to ensure the hygiene and safety of the product and facilitate storage and transportation.
2.3 Key Factors Affecting Screw Extrusion Puffing Effect
The effect of screw extrusion puffing directly affects the quality of pet food. There are many factors affecting the puffing effect, 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. jéel bix, 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, le materiales ku fáciles u pegar ti' le tornillo yéetel le barril, ku beetik u k'astal le extrusión yéetel le inflamación; wa le contenido humedad jach t'okik, u muuk'il cizallamiento yéetel u muuk'il fricción ichil le materiales ku insuficientes, yéetel u gelatinización le almidón ma' chuka'an, ts'áaik tumen resultado jump'éel k'aak'as efecto u hinchado.

Chen ba'ale, wa u velocidad le tornillo jach ka'anal, u k'iinil u p'áatal le ba'alo'ob te' cavidad extrusión jach kóom, 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.
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. The size of the die hole determines the initial diameter of the product. The smaller the die hole size, the greater the extrusion pressure, yéetel le utsil le efecto puffing, ba'ale' u páajtalil u beeta'al yaan u xu'ulul.
