Twin screw extruder is very suitable for pet feed. The energy consumption of twin-screw is lower than that of single screw by kneading and rubbing each other. In this way, the material can be kneaded and ripened more fully, the overall ripening degree can reach more than 95%, the stability of the product in water can be maintained at more than 24h, and the surface finish and particle uniformity of the particles are also better. After the extruded feed is fully cooked, the animals will not only taste good, but also have high digestibility and easy to absorb nutrients.
The biggest characteristic of twin-screw extruder is that it can mix all kinds of raw materials without considering its composition. Therefore, such diverse components as grains, soybean meal, animal meal, fresh meat, fat, nutrients, protein, vitamins, starch and wet fish residue can be easily processed. Therefore, the twin-screw extruder can be used to process feed with low viscosity and high viscosity. In terms of aquatic feed, such as fish feed, shrimp feed, eel feed and high-grade ornamental fish feed, all need to use twin-screw extruder, especially for micro aquatic feed, high-fat aquatic feed and feed with small production but constant formula. In pet food processing, the main components of pet food are generally composed of grain flour (such as wheat flour) and animal flour with high protein content, fresh meat and fat.
