Fish Feed Extruder Overview
Fish feed extruder is a kind of equipment which uses high temperature and high pressure extrusion technology to process raw materials into pellet feed. It is mainly composed of main machine, electronic control system, feeder and seasoning machine.
Fish feed extruder processing flow
Select fresh and high-quality feed raw materials, mix cereals, beans, fish meal and other materials in proportion, and perform pretreatment such as screening and vacuuming.
The screened raw materials need to be crushed by a flour making machine. Remember not to crush the raw materials too finely, otherwise it will affect the puffing effect.
Mix various raw materials in a certain proportion, and add various required vitamins, minerals and other auxiliary materials for full mixing.
Add an appropriate amount of water to the mixed feed. This step is very critical. Too high or too low moisture will affect the puffing effect.
Control the humidity and pressure within an appropriate range, send the mixed feed into the puffing chamber in one direction, and slowly enter under high pressure to produce pressing.
When the feed enters the puffing chamber, due to the decrease in pressure in the puffing chamber, the water evaporates quickly to form a gas state, the inside of the feed particles expands rapidly, and puffs evenly in the puffing chamber to form granular feed.

FAQ
1. Q: How much energy does a fish feed extruder consume?
A: The energy consumption of a fish feed extruder depends on its specifications and production efficiency. Usually, during use, the equipment has stable power and relatively low energy consumption.
2. Q: How to control the moisture content of a fish feed extruder?
A: Add an appropriate amount of water to the mixed feed and mix it thoroughly after adding water. Continuous water spraying through a quantitative water sprayer is also an effective method of moisture control.
3. Q: How to choose a fish feed extruder that suits you?
A: When choosing a fish feed extruder, you need to consider factors such as the equipment's production capacity, production efficiency, product quality, and energy consumption, as well as your own production environment and purpose.
