Bugu da kari, bisa ga bukatun sarrafawa, 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.
Na uku, 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. A lokaci guda, da gelatinized sitaci kuma iya inganta danko da dauri karfi na kayan, yin samfurori da aka fitar da su suna da siffar mai kyau da laushi.

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. Misali, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Na biyar, post-processing. The extruded puffed particles need to go through post-processing links such as drying, sanyaya, 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, girman barbashi, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. Misali, 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 raga. 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 mintuna, 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. Misali, 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 ku 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. Duk da haka, 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: sashen ciyarwa, 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, 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. Our Extruders: Advantages and Product Series for Pet Food Production
We have long been engaged in the research, development and production of food-grade extruders, and have developed a series of twin-screw extruders specially suitable for pet food production according to the characteristics of pet food processing and the needs of enterprises. Our extruders have the advantages of low operating cost, wide application range, advanced technology and reliable process control, which can meet the processing needs of various types of pet food and help enterprises improve production efficiency and product quality.
3.1 Main Advantages of Our Extruders
3.1.1 Low Lifetime Operating Cost:
We focus on the durability and economy of the equipment, and adopt high-quality materials and advanced manufacturing technology to ensure that the extruder has a long service life and low operating cost. The inner wall of the barrel is made of high-quality wear-resistant alloy steel, which has extremely strong wear resistance and can effectively resist the wear caused by the friction between the materials (especially the materials containing hard particles such as bone meal) and the barrel. This greatly extends the service life of the barrel, reducing the frequency of barrel replacement and the maintenance cost of the equipment.
Bugu da kari, we also provide professional barrel wear measurement services. Our technical team will regularly or irregularly detect the wear of the barrel for customers, accurately judge the wear degree of the barrel, and provide professional suggestions on barrel replacement. This ensures that customers only replace the barrel when it is really needed, avoiding unnecessary waste and reducing the operating cost of the equipment. A lokaci guda, the screw of our extruder is also made of wear-resistant alloy steel, which has good corrosion resistance and wear resistance, and can adapt to the processing of high-fat, high-protein and high-salt raw materials.
3.1.2 Faɗin Aikace-aikacen:
Our twin-screw extruders have strong adaptability and can meet the processing needs of various types of pet food, including dry puffed products, Semi-rigar kayayyakin, samfurori masu laushi masu laushi, 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, ganga, 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. Misali, 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, matsa lamba extrusion, dunƙule gudun, material moisture content and production capacity in real time. If any parameter exceeds the set range, tsarin zai ba da sanarwar ƙararrawa cikin lokaci, and even automatically shut down the equipment if necessary, to avoid equipment failure and product quality problems. Bugu da kari, 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, siffa, taurin, crispness and nutritional composition of the products are uniform, which can meet the strict quality requirements of pet food. A lokaci guda, 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:
Our twin-screw extruders have high production efficiency, which is much higher than that of single-screw extruders. 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. Bugu da kari, the self-cleaning function of the twin-screw extruder can reduce the time of equipment cleaning and maintenance, further improving production efficiency.
