Food extruder is a kind of equipment for processing extruded food, which is widely used in food, feed and industry. Based on extruder (dry method, wet method, single screw or twin screw), we will introduce the composition of food extruder here. The main parts, these main parts are:

1. Discharge die of food extruder: It is the end point for the product to pass the extruder. It has a great influence on the shape, texture,density,appearance,characteristics of the product and the production volume of the extruder.

(1) The bearing box part is mainly composed of the bearing box body, the main shaft, the bearing, the shaft sleeve, the left and right end covers, the sealing ring, and the round nut.

(2) The oil filter cooling system is mainly composed of oil pump, cooler, oil filter, valve, connecting pipe fittings, etc.

2. Food extruder screw: It is the main component of the extruder. The parameters of the screw structure include diameter, pitch, root diameter, and screw.angle and blade section structure. The length-to-diameter ratio of the extruded parts and the clearance between the screw and the inner wall of the expansion cavity also have a great influence on the performance of the extruder.After a reasonable combination of these parts, a food extruder is formed, so that it can operate normally.
