Extruder and floating fish feed processing technology

by Lima Machine Lima SEO

The extruder is used for the production of feeds for poultry, pets, aquatic products, etc. The output is uniform, the length can be adjusted, and the palatability is good. Among them, the extruder has been upgraded to strengthen the fuselage, increase the reinforcement of the feeding port, have a larger capacity, wear-resistant and durable, and is easy to install and disassemble. 

While reducing costs, it also meets the production of feeds with different tastes such as pigs, cattle, sheep, rabbits, fish, and pets.


Processing requirements for different materials in the production of puffed materials:

Under normal circumstances, the finer the various raw materials used for extruded feed are, the better, and strict aquaculture farmers meet their fineness requirements through ultra-fine grinding of an 80-mesh (0.18 mm aperture) sieve. The finer the particles of the raw material, the higher the digestibility, granulation fastness and water stability; in addition, the feed additives should be pre-mixed to make a 4%-5% mixture, and then mixed into the feed in order to maintain a certain uniformity.  And you can go to see other type animal feed machine like chicken feed mixer machine.

Extruded material production process:

Some heat-sensitive vitamins should be added to the extruded powder. First, steam or water at about 100 °C is added to the powder to make the water content reach 25%, and then the hot powder is passed through the extruder barrel. Under the pressure of about 140 ℃ and 6 kg/m2, it is sent to the compression molding device, and then the pressure drops rapidly, and the evaporation of super hot water causes the expansion of the particles (granulation). After the expansion, the grease is immediately sprayed on the surface of the particles to ensure The granulation surface is smooth. At this time, the pellet feed is once again sent to the heating channel to evaporate, reducing its water content to less than 10%, and finally cooled to room temperature to form extruded pellet feed.

The mineral pre-powder can be added before the raw material is pulverized, and the vitamin pre-powder should be added after the raw material is pulverized and mixed. The purpose of this is to reduce the loss of vitamins during processing and heating. The particle size should generally be 1-2 mm, which is convenient for fish and shrimp to eat, otherwise, it will cause waste due to poor palatability of the feed.
