Moekara, the particles of puppy food are smaller and shorter, while the particles of adult dog food are larger and longer.
Te paeraa, post-processing. The extruded puffed particles need to go through post-processing links such as drying, te toetoe, 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, e tae noa'tu i te mau huru o te mau tao'a mata, tempering parameters, Te mau tapa'o extrusion e te hamaniraa i te upoo. 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 Te mau huru o te mau tao'a mata:
Te huru, te rahi o te hu'ahu'a, moisture content and nutritional composition of raw materials have a great impact on the puffing effect. Moekara, 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, I te 'āmui 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%. Mai te mea e, e mea rahi roa te haumi, 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 miniti, 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. Moekara, 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 Te mau taahiraa:
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 a 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. Āre'a, 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: tuhaa tamaaraa, 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, E faarahi te reira i te faaohiparaa i te ito e te mauiui o te mau ravea; mai te mea e, e mea iti roa te faaheporaa, the puffing effect is poor, and the product is loose and easy to break.
