Single-helical fish feed extruder is a floating feed machine that has mainly designed for fish feed production. Having a higher feed conversion ratio, the fish feed produced using the single-helical fish feed extruder can maintain the high quality of fishpond water.
Single-helical fish feed extruder includes two types of fish feed extruder (i.e., dry and wet fish feed extruder) meeting the increasingly growing fish feed production. The simple structure of this machine makes its operation easy.
Some of the functions of single-helical fish feed extruder
- Cohesive function: The raw materials can closely combine together during extrusion process.
- Degassing: The blister in the feed raw material is eliminated during the expansion process.
- Dehydration: Generally, the water content of the feed material is reduced during the fish feed extruding process by about 4%-7%.
- Expansion effect: The operation condition and configuration of the single-helical fish feed extruder is capable of controlling the feed density causing it to float or sink.
- Gelatinization: High temperature and extrusion process lead to stickiness of starch in fish feed.
- Homogenization: By homogenizing the mixture, the extruder turns the appearance of the raw material into a more acceptable form.
- Sterilization: During feed expansion process, pasteurella bacterium in raw material is eliminated through extrusion technology.
