As a kind of feed processing equipment, the wet type floating fish feed pellet mill can make fish pellets from corn, bean pulp, corp stalk, grass, rice hull and so on. The wet type fish feed extruder machine is widely used in making both floating fish feed and sinking feed pellets for aquaculture farms, feed mills, livestock farms and poultry farms. Different from the dry type floating fish feed pellet mill, the wet type is equipped with a boiler which can continuously steam the materials to make pellets.the feed pellet machine is a crucial machine for making high-quality fish pellets and pet food.The working principle of wet type is similar to dry type. But the former needs to add water or steam into the machine to increase the moisture to 20 percent, or more than 30 percent during the process. the fish feed making machine increases the temperature of the materials by steaming.The feed pellet made by wet type fish feed pellet machine is more smooth and with better quality because the material is ripen and mixed enough in the conditioner compared with the dry type .
The capacity of the the dry type feed pellet machine is lower than the wet type fish feed pellet machine, so usually the dry type fish feed pellet machine is better and economic for the small and medium size user or factory.
The Working Process of Floating Fish Feed Pellet Extruder(Dry Type)
When the raw material is sent into feeding device, they will be pressed by the screw shaft with high pressure and temperature which can make the raw material fully cooked and sterilized. Then the pressed material will be formed into pellets by shaping mold. After that a cutting device will cut the formed pellets into different length as required.
Merits of Feed Pellets Made by Fish Feed Pellet Mill
1.Feed pellets are germfree, well cooked, and easy to digest for the fishes.
2.The protein of the materials is denaturalized after being processed by the floating fish feed extruder. It rises the digestibility and tastiness of the feed.
3.The pellets are light, so that they can float on the surface of water. It reduces waste of feed and pollution of the water.
4.Feed pellets contains low moisture, which is convenient for storage and transportation.
