The working principle of fish feed puffing machine is mainly to make the raw materials uniform through heating, pressure, stirring and other methods, and to gelatinize the starch in the raw materials to a certain extent, thereby increasing the water absorption and adhesion of the raw materials, making them easier for fish to digest and absorb. ‌‌12
The fish feed puffing machine is mainly composed of a feeding system, a heating system, a main transmission system, a lubrication system, and a safety protection system. The feeding system is responsible for feeding raw materials into the machine, the heating system is responsible for heating the raw materials to a certain temperature, the main transmission system is responsible for pushing and stirring the raw materials, the lubrication system is responsible for lubricating the machine, and the safety protection system is responsible for the safety protection of the machine.
During the working process, the feed enters the extruder through the feeding system, and is subject to the high-speed rotation of the screw and the high temperature and pressure environment. After being exposed to high temperature for a short time, the starch in the feed is gel, the protein is denatured, and the cellulose becomes more digestible. Next, after passing through the expansion chamber, the feed is rapidly expanded and forms granular feed under the action of the cutting device. Finally, the feed is solidified, cooled, and the desired product is obtained through a cooling device.
The advantages of fish feed puffing machine include high production efficiency, high nutritional value of the produced feed, and easy digestion and absorption by fish. The application of this equipment can significantly improve the efficiency of aquaculture, meet the nutritional needs of fish, and improve the digestibility and energy utilization of feed.
