what is the characteristics and classification of food puffing extruder

Features of food extruder:

The current extruder products have become more and more advanced with the advancement of science and technology. Now the new type of twin-screw extruder has developed relatively late in China. After this kind of mechanical compound material is sent to the conditioner by the conveying equipment, the material is conditioned and tempered. After being quenched and tempered by high-temperature steam in the device, it enters the puffing mechanism from the discharge trough, and is instantly extruded and cut into granules from a certain shape of the die hole under the pumping of a pair of mutually parallel and meshing screws. Due to the wide variation range of the extruded raw material characteristics, the screw speed needs to be adjusted within a wide range. The arrangement of the thrust bearing gearbox is more complicated, resulting in an increase in equipment cost. For example, the single screw adopts the first-stage transmission of the belt, while the twin-screw extruder adopts the gearbox to drive, and the two have great differences in manufacturing and transmission efficiency.

Classification of food extruder:

There are many types of common puffing machines according to the use of processing materials, etc. According to the categories of food processing, they can be divided into grain puffing machines, flour puffing machines, soybean puffing machines, etc. The main purpose of the grain puffing machine is To puff yellow rice, corn and other whole grains and other grains; the function of the flour extruder is to puff wheat white flour, and other flour food products. This kind of extruder is also called a crispy fruit machine; Soybean puffing machine, the main function of soybean puffing machine is generally used for puffing soybeans. Unlike the grain puffing machine we just mentioned earlier, the soybean puffing machine contains a device for removing oil, which is based on the oil content of soybeans.
