1. This extruder equipment adopts the auto-controlling speed feeding tool to produce the feed material evenly.

2. Electric heating device is adopted which can improve the feed expansion rate and pellets floating time.

3. High temperature and high pressure cooking process can kill the salmonellosis and bacterial infections and also makes the pellets easily to digest.

4. The cutting knife adopts the frequency controlling speed in order to change the material size.

5. The floating time can be controlled by the puffing degree adjustment.

6. Auto-temperature control system makes the temperature controlling more direct viewing and the parameter more precise.

Working Principle of Dry Type Fish Feed Machine

There is no need to heat outside the machine, through the screw extruding of the raw material, heat is produced and gathered during the rotary working process in the airtight environment, and during the high temperature ripening process, the starch and fiber of the raw material become swell. Then under the pressure-tight condition, material will be formed into pellets by shaping mould. At the end, through the high pressure produced by the regular rotating of the screw, after being cut by the forepart cutter which rotates regularly and high-speedily, the finished products will be shrunk and become small average puffed balls in room temperature and pressure.
