Feed expanding machine to improve the settlement performance of feed in the water through the expansion process parameters are set, can be made into a variety of settlement speed of expanded feed, such as floating, slow sinking and sinking, etc., in order to meet the requirements of the different habits of aquatic animals, reduce feed loss, avoid water pollution. For example, the floating feed with loose texture and porous is suitable for the upper layer of fish to feed.
Due to the special use of puffed feed is good, mostly used in the production of pet feed, aquatic feed and suckling pig feed. In use, it should be noted that extruded puffing has a certain destructive effect on vitamins and amino acids, etc., and has high power consumption, low yield and high cost, but it can generally be compensated from the improved feed remuneration.
