Dry Type Vs Wet Type Fish Feed Extruder


What Is Dry Type Fish Feed Extruder?

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

The completely dry type fish feed extruder is primarily utilized for the manufacturing of marine feed, such as making fish feed pellets, tilapia feed, catfish feed pellets, shrimp feed, crab feed, turtle feed, fish feed pellets, etc. The completed pellet feed is extruded at heat with the heating plate in the dry type fish feed maker.

Consequently, the completed granules can drift on the water for about 24 hr due to being puffed. Ended up bit 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 up to a bigger 15mm. dry type machine heating the material by electrical home heating plate, this completely dry type machnine squeezes out the material from the holes of the die under the action of the screw extruder.

When the pellets come out of the machine, the stress and temperature decrease greatly, and the water vaporizes. The product is then increased into bits with a permeable structure. Throughout animal feed pellet machine price , wetness varieties from 15% to 20%.

Working Principle Of Dry Type Fish Feed Extruder

when extrusion procedure, the product from the open end of the extrusion cavity input, by the screw transportation to the entire extrusion dental caries, and after that the supporting extrusion component right into a number of locations, in each location in between the positioning of a ring (pressure ring) as the circulation and stress control, the screw sharing activity to advertise the product circulation through the ring gap in between the pressure ring and the within the cavity, the mechanical energy generated by the rotational motion of the screw into heat The friction between the material and the parts of the dry type fish feed extruder equipment and also the internal friction of the product.

As the material is squeezed out via the die hole at the end of the blowing dental caries, the dough-like material is refined right into a specific shape, and due to the big propulsion of the screw in the blowing dental caries of the dry type fish feed equipment, a huge pressure is produced.

Forming in the product, when these materials are squeezed out from the die opening, a huge amount of water in the product evaporates promptly, which significantly lowers the wetness material of the product.

What Is Wet Type Fish Feed Extruder?

Wet type fish feed extruder maker is additionally extensively used to create basic materials right into state-of-the-art drifting aquatic feed pellets, which appropriates for fish, catfish, shrimp, crab, cat, dog and other pet dogs. The raw products utilized by the damp type fish feed maker are wheat, soybean, cake and also various other scraps, and so on, as well as the puffed fragments created by the wet type fish feed extruder equipment can float on the water surface for more than 24 hr without dissolving.

Wet type feed extruder machine are mostly utilized in huge as well as medium-sized feed processing plants as well as ranches. it works with the vapor central heating boiler, the boiler continually can supply hot steam to the damp type fish feed maker extrusion component.

manual pellet machine of the wet type machine is similar to that of the completely dry type fish feed extruder device. Yet the damp type calls for adding water or heavy steam in the wet type fish feed device to boost the dampness to twenty percent, or greater than thirty percent during handling. It raises the temperature of the material by vapor.

Functioning Principle Of Wet Type Fish Feed Extruder

the damp type fish feed equipment contains screw, barrel, template, fixture, etc. The screw and also barrel are combined in sections, and also the compression level can be readjusted according to the type and also needs of the extruded feed, as well as the development degree of the extruded feed can be altered.

When the raw material enters the loading gadget, no added heating is required and also the screw is pressurized at high pressure as well as heat to totally cook and also sanitize the raw material.

Throughout the heat curing process, the starch as well as fibers in the raw material broaden. The material is after that built into pellets via the molding die under pressure-sealed problems.

Ultimately, the high pressure created by the regular rotation of the screw is cut by the routine high-speed rotation of the front cutter, as well as the ended up item is reduced right into an ordinary little puffed sphere at area temperature and also pressure.
