　　Pet feed puffing machinePurpose and scope of application

SPHS145a wet puffing machine is suitable for puffing soybeans, pet feed, floating feed such as cow feed, sea bass feed, etc., and submerged feed such as shrimp feed, crab feed, etc.

　　Pet feed puffing machinePerformance Characteristics

1. The structure of this machine is reasonable, the appearance is beautiful, and the operation is stable and reliable. The working parts are made of special wear-resistant alloys, with high output and low power consumption. It has the characteristics of wear resistance, high efficiency, easy installation, operation, and maintenance.

2. The machine adopts a wet puffing process, which is characterized by the need for conditioning treatment before the raw materials enter the puffing chamber to increase the temperature and humidity of the materials, and some of them begin to gelatinize and mature before entering the puffing chamber for puffing. The feeding and cutting devices of the machine are controlled by variable frequency motors and equipped with an external discharge mechanism.

working principle

The working principle of a wet puffing machine is as follows: the material is fed into the conditioner through a speed regulating feeder, and steam is introduced into the conditioner for tempering treatment. At the same time, a certain amount of water is added for humidification, so that the material is matured and gelatinized, and a certain amount of water is added to reach 25% to 30%. Then, it enters the puffing system through a three-way bucket. The puffing system is divided into three working stages, namely the feeding section, the conveying section, and the forming section. It is mainly composed of a screw sleeve and a screw. The main motor is reduced by a belt and drives the screw shaft through the transmission box. The material first enters the feeding section of the puffing system, enters the conveying section in the feeding section, and then enters the forming section. Under the thrust of the screw, it is strongly squeezed and sheared, Zui is then extruded from the extrusion die, and the material is cut into qualified particles by a cutting system and a cutting knife. During the extrusion process of the expansion system, steam or cold water at a certain pressure is also introduced between the interlayer of the screw sleeve to keep the material warm or cool, preventing the material from burning due to too low a temperature that cannot meet the expansion requirements or too high a temperature. Generally, the temperature of the expanded material before exiting the die is around 130-160 ℃. The temperature of producing heavy feed before molding is generally below 60 ℃. Below is a detailed description of the working principle of the puffing system.

The puffing system can be divided into three stages, which can be simply described as a screw conveyor. The material (powder) is fed in from one end, passes through the equipment, and is sent out from the other end. During the transportation process, the product undergoes significant changes. In Figure 2, it can be seen that the puffing system consists of three parts. The processing of the puffing system is a continuous process, and the length of the three stages depends on the processing conditions, the products to be processed, and the puffing machine itself.
