China pet feed pellet machine price

Wet pet feed pellet machine and dry pet pet feed pellet machine are introduced. 

There are two kinds of extruding feed using twin screw pet feed pellet machine, one is dry extruding feed, the other is wet extruding feed. Below we analyze and compare two different extrusion methods in pet feed extrusion process, dry extrusion feed needs to add water to raw materials in the production process. The heat produced in the extrusion process is generated by the screw, the shearing plate and the extrusion cavity under the action of the pet feed pellet machine. 

The difference between wet pet feed pellet machine and dry pet feed pellet machine is that the raw material is prepared prior to extrusion, by steam or water to raise the temperature and pre-curing. The so-called conditioning refers to the use of steam on pet food raw materials, so that the starch in the raw materials pre-slacking, Denaturation, material softening, therefore, it is beneficial to improve the extrusion and granulation effect and the extrusion quality of dog food. 

Wet extrusion also has the advantages of good extrusion effect and stable extrusion rate. In the process of dog food processing, wet pet feed pellet machine and pre-adjustment technology is of great significance. However, compared with the dry extrusion process, there are some defects such as expensive equipment, equipment requirements, equipment control and so on. According to the quality adjustment method, it is the above dry and wet extrusion method. Can Be divided into single-screw pet feed pellet machine and twin-screw pet feed pellet machine. Single screw pet feed pellet machine expansion process is relatively simple, widely used. Can Be used for high water content, fat content of more than 17% of the products, starch and carbonization degree can reach more than 90% .Compared with single-screw extruder, twin-screw extruder is more complicated in equipment and structure, but it has the advantages of stable extrusion performance, high product yield, high production efficiency and basic.
