Technical Features of Floating Fish Feed Extruder

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.

Twin-Screw Extruders

In order to create a design with greater operating flexibility and with greater operational control, twinscrew machines were developed. Twin-screw extruders can be co-rotating, counter-rotating, intermeshing or non-intermeshing in terms of basic designs. Co-rotating, intermeshing screw designs have dominated that scene as far as these extruders are concerned. This is because of relative ease of design and manufacture compared to counter-rotating designs.The screw design of twin-screw extruders can 

affect operating efficiency and machine capability. Screw components in the feed section of the barrel can be single, double or even triple flight arrangements. With more flights intertwined on the shaft, the conveying capacity of the screw is reduced but the residence time distribution is lower. This promotes a first-in, first-out movement of the extrudate. However, double- and triple flighted screws produce more shear across the screw channel and therefore, improved processing uniformity.
