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.

The dry type fish feed extruder 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, etc. The completed pellet feed is extruded at high temperature via the heating plate in the dry type fish feed equipment.

Therefore, the finished granules can float on the water for about 24 hr due to being puffed. Completed bit sizes 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 etc up to a larger 15mm. dry type machine warming the product by electrical home heating plate, this 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 drop dramatically, as well as the water vaporizes. The product is after that increased into bits with a porous structure. During this process, dampness ranges from 15% to 20%.

When extrusion procedure, the product from the open end of the extrusion cavity input, by the screw transportation to the whole extrusion dental caries, and after that the supporting extrusion part right into a number of areas, in each location between the placement of a ring (pressure ring) as the circulation and pressure control, the screw sharing action to advertise the material circulation with the ring void between the pressure ring and also the inside of the dental caries, the power produced by the rotational motion of the screw right into warm The rubbing in between the product and the parts of the dry type fish feed extruder maker and the inner rubbing of the product.

As the product is extruded with the die hole at the end of the puffing tooth cavity, the dough-like material is refined right into a certain form, and also due to the big propulsion of the screw in the puffing tooth cavity of the dry type fish feed equipment, a substantial pressure is generated.


Developing in the material, when these products are extruded from the die hole, a large amount of water in the material vaporizes instantly, which considerably reduces the dampness content of the material.

What Is Wet Type Fish Feed Extruder?

Wet type fish feed extruder machine is likewise commonly utilized to produce raw materials right into high-grade floating aquatic feed pellets, which appropriates for fish, catfish, shrimp, crab, cat, pet dog and also various other pets. fish feed making machine price utilized by the damp type fish feed equipment are wheat, soybean, cake as well as other scraps, and so on, as well as the puffed fragments produced by the wet type fish feed extruder equipment can float on the water surface for greater than 1 day without liquifying.

Wet type feed extruder equipment are primarily utilized in big and also medium-sized feed handling plants and ranches. it deals with the vapor central heating boiler, the central heating boiler continuously can supply hot heavy steam to the damp type fish feed equipment extrusion part.

The functioning principle of the damp type equipment resembles that of the dry type fish feed extruder equipment. But the wet type calls for adding water or heavy steam in the damp type fish feed equipment to boost the wetness to twenty percent, or greater than thirty percent during handling. It raises the temperature of the material by steam.

Functioning Concept Of Wet Type Fish Feed Extruder

The wet type fish feed machine contains screw, barrel, theme, fixture, etc. The screw as well as barrel are integrated in areas, and also the compression level can be readjusted according to the type and also demands of the extruded feed, as well as the expansion level of the extruded feed can be transformed.

When the raw product enters the loading tool, no extra home heating is required and also the screw is pressurized at high pressure and high temperature to fully prepare as well as sterilize the raw product.

During the high temperature healing procedure, the starch as well as fibers in the raw material increase. The material is after that molded right into pellets through the molding die under pressure-sealed problems.

Ultimately, the high pressure produced by the normal turning of the screw is reduced by the regular high-speed turning of the front cutter, and the ended up item is shrunk into a typical small puffed round at space temperature level as well as pressure.
