The feed pellet machine generally has three types, including soft feed pellet machine, hard feed pellet machine and feed extruder machine.

The soft pellet feed machine is the earliest and most general type, with simple structure and low cost. It has a wide range of raw materials, and can be used as a variety of formulations of concentrates, coarse materials, green materials or different kinds of additives to produce pellet feed for fish. After the feed is formed by the soft feed pellet machine, the nutrients remain unchanged, and it is practically used for feeding middle and grassroots fish.

The productivity depends on the feed material. If there is a lot of coarse material, the productivity will be lower. The water content of the soft pellets machined feed is as high as 20%-30%, and it is not suitable for storage. It will melt shortly after entering the water, and the temperature of the pellet will be 43-55℃. It is suitable to add anti-fish disease drugs. Does not destroy vitamins and has low processing costs. The disadvantage is that the output value per kilowatt-hour is low and it is easy to wear. The number of implementations is not too large.

Hard pellet feed machine is a kind of rapid development and more applications in the world. The nutrient content and grade of the pellet feed processed by the hard pellet machine have been improved. It is mainly used to press materials with relatively low moisture content (below 13%). If the moisture content of the material is greater than 17%-18%, the paste will occur which will cause the mold hole to be blocked. Please pay attention to it when using it. Hard pellet feed has a low moisture content and is convenient for...
