1. The puffed feed has good palatability, which can effectively avoid the grade change of the feed, and will not affect the use effect due to the uneven nutrition;
2. Various pressure and mechanical effects during the expansion process can improve the gelatinization degree of starch in the feed, destroy and soften the cell wall portion of the fiber, denature the protein, improve the stability of the fat, and improve the digestibility and utilization rate of the feed. At the same time, the fat penetrates from the inside of the granule to the surface, so that the feed has a special scent, which is beneficial to increase the appetite of the animal.
3, feed ingredients after high temperature, high pressure puffing can kill a variety of harmful bacteria, thereby effectively reducing the body's digestive tract disease.
4, can be made into a variety of sedimentation speed of puffed feed, such as floating, slow and sinking, to meet the different living habits of aquatic animals, reduce feed losses, avoid water pollution.
5. Products with different shapes can be produced according to animal preferences. For example, cat feed can be made into fish shape, and dog feed can be made into ribs, which greatly improves the appearance and attracting value of feed.
6. Some young animals with underdeveloped digestive organs or fur animal animals with relatively short digestive systems are difficult to digest complex feeds, and they can use puffed feed that is easier to digest and absorb.
7. It has a special role in the development and utilization of feed resources, such as the production of full-fat soy flour, puffed feather meal, blood meal, etc. by using a puffing machine;
8. The expanded feed has a low moisture content and is convenient for long-term storage.
