Floating Fish Feed Machine Working process:
After the material is sent into feeding device, they will be pressed by the screw shaft with high pressure and temperature which makes the raw material fully cooked and sterilized.

After that a cutting device will cut the formed pellets into different length as required.

3.The floating time can be controlled by the puffing degree adjustment.
4.Floating fish feed machine can make pellet from dia.1.0mm-20mm just by changing the mold.
5.Electric heating device is adopted which can improve the feed expansion rate and pellets floating time.
6.High temperature and high pressure cooking process can kill the salmonellosis and bacterial infections and also makes the pellets easily to digest.
7.The cutting device can be adjusted to make pellets of different length.
8.The wet type extruder needs a boiler to make steam which can conduct steam to the conditioner and ripen the raw material in advance.
