1.Function of 75 type extruder:

The application field of twin-screw extruder covers the deep processing of agricultural products, such as breakfast instant porridge, nutritional rice, instant rice, breakfast cereal food, leisure puffed food, silk drawing protein, modified starch, pet food, aquatic feed and other processing fields.

Twin screw extruder is composed of feeding system, extrusion system, rotary cutting system, heating system, cooling system, transmission system and control system. The machine is suitable for a wide range of raw materials, various production products, variable frequency speed regulation, high degree of automation, stable operation and long service life.

The full-function twin-screw expansion host has better equipment performance. The gear box is solid and durable. The screw uses a combination of building blocks, which is applicable to a wider range of products. The barrel uses an embedded alloy sleeve structure, which is more wear-resistant and durable.
