Dry Type Vs Wet Type Fish Feed Extruder

What Is Dry Type Fish Feed Extruder?

There are two kinds of fish feed equipments for making floating aquatic feed, one is dry type fish feed extruder, the other is wet type fish feed extruder.

chicken litter pellets processing machine is mostly utilized for the manufacturing of aquatic 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 home heating plate in the dry type fish feed equipment.

As a result, the ended up granules can float on the water for regarding 24 hr due to being puffed. Completed 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 approximately a larger 15mm. dry type machine warming the material by electric heating plate, this dry type machnine squeezes out the product from the holes of the die under the action of the screw extruder.

When the pellets come out of the maker, the pressure and temperature decline sharply, and also the water vaporizes. grain pellet mill for sale is after that broadened right into particles with a permeable structure. Throughout alfalfa pellet mill for sale , wetness arrays from 15% to 20%.

Functioning Principle Of Dry Type Fish Feed Extruder

When extrusion operation, the material from the open end of the extrusion dental caries input, by the screw transportation to the entire extrusion cavity, and afterwards the auxiliary extrusion part right into a number of locations, in each area in between the placement of a ring (pressure ring) as the circulation and also stress control, the screw communicating activity to advertise the product flow through the ring gap in between the stress ring and the inside of the tooth cavity, the power produced by the rotational activity of the screw right into warmth The rubbing in between the material and the parts of the dry type fish feed extruder maker as well as the inner friction of the product.

As the material is extruded with the die hole at the end of the blowing dental caries, the dough-like product is processed right into a certain shape, as well as as a result of the substantial propulsion of the screw in the puffing cavity of the dry type fish feed equipment, a big pressure is generated.

Developing in the product, when these materials are extruded from the die opening, a big amount of water in the material vaporizes promptly, which significantly lowers the moisture material of the material.

What Is Wet Type Fish Feed Extruder?

Wet type fish feed extruder maker is likewise widely used to create raw materials into high-grade floating aquatic feed pellets, which appropriates for fish, catfish, shrimp, crab, feline, pet dog and other pet dogs. The raw products utilized by the damp type fish feed equipment are wheat, soybean, cake and also other scraps, and so on, as well as the puffed particles created by the damp type fish feed extruder equipment can float on the water surface for more than 1 day without dissolving.

Wet type feed extruder machine are mostly used in big as well as medium-sized feed handling plants as well as farms. it deals with the heavy steam central heating boiler, the boiler continually can supply hot heavy steam to the damp type fish feed equipment extrusion component.


The working principle of the damp type equipment resembles that of the dry type fish feed extruder machine. But the damp type requires including water or vapor in the wet type fish feed machine to enhance the wetness to twenty percent, or greater than thirty percent during processing. It raises the temperature of the product by vapor.


Functioning Principle Of Wet Type Fish Feed Extruder

The damp type fish feed machine includes screw, barrel, theme, fixture, and so on. The screw as well as barrel are combined in areas, as well as the compression degree can be changed 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 product enters the loading gadget, no extra home heating is required and also the screw is pressurized at high pressure and heat to fully cook and disinfect the raw material.

During the heat treating process, the starch and also fibers in the raw material broaden. The product is after that built right into pellets through the molding die under pressure-sealed conditions.

Lastly, the high pressure created by the normal rotation of the screw is reduced by the normal high-speed rotation of the front cutter, and also the ended up item is diminished right into an ordinary small puffed ball at room temperature level as well as stress.
