What Is Dry Type Fish Feed Extruder?

There are chicken manure fertilizer pellet making machine of fish feed devices for making drifting aquatic feed, one is dry type fish feed extruder, the other is wet type fish feed extruder.

The dry type fish feed extruder is generally used for the manufacturing of water feed, such as making fish feed pellets, tilapia feed, catfish feed pellets, shrimp feed, crab feed, turtle feed, fish feed pellets, and so on. The ended up pellet feed is extruded at high temperature with the heating plate in the completely dry type fish feed machine.

As a result, the ended up granules can drift on the water for regarding 24 hours because of being puffed. 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 as much as a larger 15mm. completely dry type machine heating up the product by electric heating plate, this completely dry type machnine squeezes out the material from the holes of the die under the activity of the screw extruder.

When the pellets come out of the equipment, the stress and also temperature decrease greatly, and also the water evaporates. The product is after that increased into bits with a porous framework. During this procedure, moisture varieties from 15% to 20%.

Functioning Concept 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 whole extrusion cavity, and after that the complementary extrusion component right into a variety of locations, in each location between the placement of a ring (pressure ring) as the flow and pressure control, the screw conveying action to promote the material flow with the ring gap between the pressure ring and the within the tooth cavity, the power created by the rotational motion of the screw right into warmth The rubbing between the product and the parts of the dry type fish feed extruder equipment and also the interior rubbing of the material.


As the material is squeezed out with the die opening at the end of the puffing tooth cavity, the dough-like product is refined into a specific shape, and because of the significant propulsion of the screw in the puffing dental caries of the completely dry type fish feed device, a big pressure is generated.

Developing in the product, when these materials are extruded from the die hole, a huge amount of water in the product vaporizes instantly, which substantially decreases the wetness material of the product.

What Is Wet Type Fish Feed Extruder?

Wet type fish feed extruder maker is additionally commonly made use of to produce basic materials into high-grade drifting water feed pellets, which is suitable for fish, catfish, shrimp, crab, feline, dog as well as various other family pets. The raw products made use of by the wet type fish feed device are wheat, soybean, cake and other scraps, etc, as well as the puffed fragments produced by the damp type fish feed extruder equipment can float on the water surface for greater than 24 hr without liquifying.

Wet type feed extruder equipment are primarily made use of in large and also medium-sized feed processing plants as well as farms. it works with the vapor central heating boiler, the central heating boiler constantly can provide warm heavy steam to the damp type fish feed equipment extrusion component.

extrusion pelletizing machine working concept of the damp type equipment resembles that of the completely dry type fish feed extruder maker. Yet the wet type needs adding water or vapor in the damp type fish feed device to raise the dampness to twenty percent, or more than thirty percent during processing. It raises the temperature of the product by steam.

Functioning Principle Of Wet Type Fish Feed Extruder

the damp type fish feed equipment contains screw, barrel, layout, component, and so on. The screw and also barrel are integrated in sections, as well as the compression degree can be adjusted according to the type as well as demands of the extruded feed, as well as the expansion degree of the extruded feed can be transformed.

When the raw product enters the loading gadget, no added home heating is called for as well as the screw is pressurized at high pressure as well as high temperature to completely prepare and also sterilize the raw product.

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

Ultimately, the high pressure created by the normal rotation of the screw is cut by the normal high-speed turning of the front cutter, as well as the finished item is shrunk into an ordinary tiny puffed round at room temperature level as well as stress.
