What Is Dry Type Fish Feed Extruder?

There are 2 sorts of fish feed equipments for making drifting marine feed, one is completely dry type fish feed extruder, the various other is wet type fish feed extruder.

The completely dry type fish feed extruder is primarily used for the manufacturing of aquatic feed, such as making fish feed pellets, tilapia feed, catfish feed pellets, shrimp feed, crab feed, turtle feed, goldfish feed pellets, and so on. The ended up pellet feed is squeezed out at heat through the home heating plate in the completely dry type fish feed maker.

As a result, the ended up granules can float on the water for about 24-hour due to being blown. Ended up particle dimensions can be 0.9 mm, 1mm, 1.5 mm, 2mm, 2.5 mm, 3mm, 3.5 mm, 4mm, 4.5 mm, 5mm, 5.5 mm, 6mm and so on approximately a larger 15mm. dry type device heating the product by electric home heating plate, this completely dry type machnine extrudes the product from the holes of the die under the activity of the screw extruder.

When the pellets appear of the machine, the stress and also temperature decrease dramatically, and the water evaporates. The material is after that broadened into fragments with a permeable framework. Throughout this procedure, wetness varieties from 15% to 20%.

Working Principle Of Dry Type Fish Feed Extruder

when extrusion procedure, the material from the open end of the extrusion tooth cavity input, by the screw transportation to the entire extrusion dental caries, and then the supporting extrusion part into a number of locations, in each location between the placement of a ring (stress ring) as the circulation and stress control, the screw conveying action to promote the product flow through the ring space between the stress ring and the within the cavity, the power generated by the rotational activity of the screw right into heat The friction in between the product and the parts of the dry type fish feed extruder equipment and the interior rubbing of the product.

As the product is squeezed out via the die opening at the end of the puffing dental caries, the dough-like product is processed right into a certain form, as well as because of the significant propulsion of the screw in the blowing cavity of the completely dry type fish feed maker, a massive pressure is generated.

Developing in the material, when these materials are squeezed out from the die opening, a big amount of water in the product vaporizes quickly, which greatly reduces the moisture material of the material.


What Is Wet Type Fish Feed Extruder?

chicken feed manufacturing machine is likewise commonly utilized to generate basic materials right into top-quality floating aquatic feed pellets, which is suitable for fish, catfish, shrimp, crab, cat, pet as well as various other pet dogs. The raw products made use of by the wet type fish feed machine are wheat, soybean, cake as well as various other scraps, and so on, as well as the puffed particles created by the wet type fish feed extruder maker can float on the water surface area for more than 24 hours without liquifying.

Wet type feed extruder machine are mostly made use of in large and medium-sized feed handling plants as well as farms. it works with the vapor boiler, the central heating boiler continuously can provide hot steam to the wet type fish feed machine extrusion part.

The functioning principle of the damp type maker is similar to that of the dry type fish feed extruder equipment. Yet the wet type calls for including water or vapor in the damp type fish feed maker to boost the wetness to twenty percent, or more than thirty percent during handling. It raises the temperature of the material by heavy steam.

Working Concept Of Wet Type Fish Feed Extruder

the wet type fish feed device consists of screw, barrel, theme, fixture, etc. The screw and also barrel are incorporated in areas, as well as the compression degree can be adjusted according to the type as well as requirements of the extruded feed, and the expansion level of the extruded feed can be changed.

When the raw product goes into the filling up tool, no additional home heating is required and the screw is pressurized at high pressure and also high temperature to totally prepare and sterilize the raw material.


Throughout the high temperature healing process, the starch as well as fibers in the raw product increase. The product is after that built right into pellets via the molding die under pressure-sealed conditions.

Lastly, the high pressure generated by the normal rotation of the screw is cut by the routine high-speed rotation of the front cutter, as well as the ended up product is shrunk right into an ordinary tiny puffed sphere at room temperature as well as stress.
