The structure of the single screw extruder is relatively simple and the price is relatively low. Its development is relatively early, its technology is relatively mature and its equipment is stable. It has been used for over 40 years in the expanded aquatic feed production as a main equipment, and is widely used in the production of low protein adult fish feed, such as tilapia, fish, grass carp and carp.

Twin-screw extruder is one kind of multi-screw extruder. It is developed on the basis of single-screw extruder. In the barrel of twin-screw extruder, two screw are placed side by side, so it is called twin-screw extruder.
