In Muyang Co., Ltd., we not only develop new feed machines, make innovations on them, but also research improved methods, tools and experience for their new applications to meet new challenge and create consistent value in our customers' feed mills.


Extrusion cooking technology is a very efficient processing method in feed production. Nowadays, nearly all auqafeed is produced using extrusion. Within extrusion processing, several processes may occur, including fluid flow, heat transfer, mixing, shearing, particle size reduction and melting, where feed materials are exposed to high temperatures for a very short time. This gives a distinct advantage over conventional pressure cooking, in which the exposure could last several minutes at high temperatures. In the extrusion of food and feed, pellet expansion (or bulk density) is one important property in product quality control and measurement during pellet manufacture, which is different from paste and spaghetti production.

Thanks to the solid expertise in extrusion, and the leading modelling techniques to improve the procedure that determines extrusion parameters as well as combining practical production trials, we had tailored many efficient extrusion solutions for our customers to process alternative aquafeed, and make improvement especially on the pellet uniformity of low-cost recipes.
