Dry type of fish feed extruder machine Heating the materials by the frictional force, this floating fish feed extruder machine squeezes raw materials out of the holes of the mold under the action of screw extruder. The pressure and temperature of the pellets sharply decreases when coming out of the machine, and the moisture evaporates. Then materials are puffed and become pellets with porous structure. During the process, the moisture ranges from 15 to 20 percent. 2. Wet type of fish feed extruder machine The working principle of wet type fish feed extruder machine 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 floating fish feed extruder machine increases the temperature of the materials by steaming. Merits of Feed Pellets Made by Fish Feed extruder 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. The fish feed extruder machine rises the digestibility and tastiness of the feed.

Difference Between Dry and Wet Fish Feed Extruder MachineFish feed extruder machine can be divided into dry type and wet type fish feedextruder according to the moisture of the raw materials.1. Dry type of fish feed extruder machineHeating the materials by the frictional force, this floating fish feed extrudermachine squeezes raw materials out of the holes of the mold under the actionof screw extruder. The pressure and temperature of the pellets sharplydecreases when coming out of the machine, and the moisture evaporates.Then materials are puffed and become pellets with porous structure. Duringthe process, the moisture ranges from 15 to 20 percent.

2. Wet type of fish feed extruder machineThe working principle of wet type fish feed extruder machine is similar to drytype. But the former needs to add water or steam into the machine to increasethe moisture to 20 percent, or more than 30 percent during the process. Thefloating fish feed extruder machine increases the temperature of the materialsby steaming.Merits of Feed Pellets Made by Fish Feed extruder1.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 thefloating fish feed extruder.
