Advantages of Expanded Pet Aquatic Feed
Pet Aquatic Feed
Pet feed Aquatic feed
Expansion is a process in which powdered materials (including starch and protein) are subjected to hydrothermal conditioning or non conditioning, and then sent into an expansion machine. Under the action of mechanical force, they are heated, pressurized, and then squeezed out of the mold hole. Suddenly, the pressure drops, and the water molecules inside rapidly vaporize, causing the material to expand and become porous particles for feeding. Expanded feed is a full price formula feed that is produced through a series of processing processes such as raw material micro crushing, batching, mixing, expansion, granulation, drying, spraying, cooling, screening, packaging, etc., with characteristics of floatability, semi sedimentation, and sedimentation.
Advantages of pet puffed feed
(1) Eliminate anti nutritional factors and improve the digestion and absorption rate of feed. There are many anti nutritional factors in feed raw materials, such as saponin, gossypol, trypsin inhibitor, etc. in rapeseed seeds, soybean meal, cottonseed meal and other raw materials. Under certain moisture and temperature, these anti nutritional factors gradually lose some activity during the expansion process, thus reducing the damage to animal endogenous Digestive enzyme, improving the digestion and absorption rate of the feed, and reducing excretion.
(2) High temperature disinfection ensures safe and hygienic feeding. The maximum temperature for extrusion can reach around 150 ° C, and the action time of the feed material at high temperature is very short, about 8 seconds. After high-temperature and high-pressure expansion, the raw materials can kill various microorganisms, insect eggs, and pathogenic bacteria in the feed, improve the quality of the feed, and reduce animal digestive diseases.
(3) Improve the palatability and flavor of the product.
The puffed product has a loose, porous, crispy structure, and has good palatability and flavor. The template can be made into different shapes of mold holes, so it can suppress puffed particle materials of different shapes and animal preferences. It can also produce special high fat feed, such as Atlantic salmon, rainbow trout and other breeding species, which have high feed fat addition, some up to 30%.
(4) Improving the gelatinization degree of starch is beneficial for the digestion and absorption of starch.
Research has found that extrusion can increase the gelatinization degree of starch in the feed from 13. 58% increased to 81. 55%, the higher the degree of swelling, the easier it is for enzymes to fully utilize. Plant based raw materials undergo high-temperature and high-pressure treatment during the expansion process, resulting in starch gelatinization and protein organization, which is beneficial for animal digestion and absorption, and improves the digestion and utilization rate of the materials. The expansion processing of aquatic feed can increase the digestion rate by 10% to 35%.
(5) Improve the digestion and absorption rate of word materials. The digestive tract of fish is relatively short, and most of them belong to gastroless fish. Therefore, the finer the food, the higher the digestion and absorption rate. The puffing process requires finer crushing of raw materials to improve the digestion and absorption of fish. At present, the crushing fineness of raw materials for high-end puffed aquatic materials such as Chinese sea water fish has reached 95% over 80 meshes, while the crushing fineness of raw materials for common varieties such as grass carp, Tilapia and Xenocypris carinata has also reached 95% over 60 meshes.
(6) Expanded vocabulary is beneficial for preservation and breeding management. Due to high-temperature and high-pressure expansion, as well as drying treatment, the moisture content of the finished product is generally required to be less than 10. 0%. Packaging generally adopts a separate sealing method for the inner and outer bags, so under the same conditions, the storage period is longer and convenient for storage.
(7) Expanded feed water has strong stability, does not collapse within 16-32 hours, and has little pollution to water quality.
Loose and porous puffed materials float on the water surface, making it easy to observe the feeding and growth of fish, which is conducive to scientific management; The high fat and dense extruded submerged material has a water stability of more than 16 hours, ensuring sufficient feeding of fish and reducing waste.
