Dry fish feed extruder does not require a steam boiler, it is cheaper and easier to operate than a wet extruder. Due to the advantages of economic and practical, dry extruder in the market has been favored by farmers. Here is a detailed introduction to the design of dry type fish feed extruder.
Dry extruding machine mainly comprises feeding system, extruding system and main motor.
1.Feeding system: to maintain a consistent feed rate, feeding system has three parts like feed hopper, feed screw and feed mixer.
Hopper: part of the feed material in the extrusion stage.
Feed screw: screw fixed on the hopper bottom transport material feed extruder system.
Feed mixer: it is to work in the hopper after stirring evenly, the material will be.
2.Extrusion system: to be responsible for the compression and cooking of the material before entering the molding area.
Extruder screw: the screw is fixed on the bottom of the hopper transport material feed extruder system.Screw and barrel are made of alloy steel. By heat treatment, they have good wear resistance and long service life.
Fodder mixing machine: the material is evenly mixed in the hopper.
The general extrusion process involves a short period of high temperature. Temperature above 100 is needed to achieve the expansion of the feed as it leaves the mold.
The high temperature of the dry extrusion is produced by the dissipation of mechanical energy from the heated surface, such as the barrel and the spiral surface, or by the shear forces between the wall and the material and the screw and the material. In addition, high temperature and high pressure treatment can kill Salmonella and bacteria infection, but also make the particles easily digested.
Mold: Different molds can be selected to make the particles of different diameters and shapes.
Knife: international advanced cutting technology.
It consists of a sharp blade. It does circular motion on the surface of the mold, which is used to cut the final product into small parts. The final particle size can be controlled by changing the speed of the tool.
3.Electric power system: main motor, feeder motor and cutter motor.
