Sinking Fish Feed Machine

As a kind of feed making machine, the wet type fish feed extruder can make fish feed 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 fish feed mill, the wet type is equipped with a boiler which can continuously steam the materials to make pellets. It is a key machine for making high-quality feed pellets for fish.

Suwnit fish feed pelleting machine is very flexible, you can customize the output configuration according to different feed types. If you are planning to start a small, medium or large scale feed pellet manufacturing business, please contact us for more details.

Extruder Machine For Fish Feed Making

Difference Between Dry and Wet Fish Feed Extruder

Fish feed making machine can be divided into dry type and wet type fish feed extruder according to the moisture of the raw materials.
1. Dry type extruder
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 extruder
The working principle of wet type is similar to dry type. But the former requires adding water or steam into the machine to increase the moisture to 20 percent, or more than 30 percent during the process. The sinking fish feed machine increases the temperature of the materials by steaming.

Why Choose Extruder for Aquatic Feed Production?

Aquaculture feed production has several challenges: the feed must be water stable, have high conversion rates while ensuring a low ecological impact. For these reasons extrusion technology is the best choice for the production of aquaculture feeds. Then what is extrusion? Feed at environment of high temperature (110-200 °C) and high pressure (25 to l00kg/cm2) and high shear force, high moisture (10% 20% or even 30%), through continuous mixing, conditioning, heating, pressure, curing, extrusion die and sudden depressurization formed a bulk porous feed pellets.
