Dry Type Vs Wet Type Fish Feed Extruder

What Is Dry Type Fish Feed Extruder?

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

The dry type fish feed extruder is mainly made use of for the production of aquatic feed, such as making fish feed pellets, tilapia feed, catfish feed pellets, shrimp feed, crab feed, turtle feed, goldfish feed pellets, etc. The finished pellet feed is extruded at high temperature via the home heating plate in the dry type fish feed maker.

As a result, the completed granules can float on the water for concerning 24-hour because of 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 etc up to a bigger 15mm. dry type maker warming the product by electric heating plate, this dry type machnine squeezes out the product from the holes of the die under the activity of the screw extruder.

When the pellets appear of the equipment, the stress and temperature level decline greatly, as well as the water evaporates. The material is then increased into bits with a porous framework. Throughout this process, moisture varieties from 15% to 20%.

Functioning Concept Of Dry Type Fish Feed Extruder

When extrusion operation, the product from the open end of the extrusion cavity input, by the screw transport to the whole extrusion tooth cavity, and after that the supporting extrusion component right into a variety of areas, in each location in between the positioning of a ring (stress ring) as the flow and also stress control, the screw conveying action to advertise the product flow through the ring gap in between the pressure ring and the inside of the tooth cavity, the mechanical energy created by the rotational motion of the screw into warm The friction between the product as well as the parts of the dry type fish feed extruder equipment as well as the inner friction of the material.

As the material is extruded via the die hole at the end of the puffing tooth cavity, the dough-like material is processed into a specific shape, and due to the substantial propulsion of the screw in the puffing dental caries of the dry type fish feed machine, a massive stress is produced.

Developing in the product, when these products are extruded from the die opening, a big quantity of water in the product vaporizes instantly, which considerably reduces the moisture web content of the product.

What Is Wet Type Fish Feed Extruder?

Wet type fish feed extruder maker is likewise commonly used to generate basic materials into state-of-the-art floating aquatic feed pellets, which appropriates for fish, catfish, shrimp, crab, cat, pet dog and other animals. The raw products used by the wet type fish feed equipment are wheat, soybean, cake and also other scraps, and so on, and the puffed fragments created by the wet type fish feed extruder machine can float on the water surface for more than 1 day without dissolving.

Wet type feed extruder maker are primarily utilized in large as well as medium-sized feed processing plants as well as farms. it collaborates with the vapor central heating boiler, the boiler continually can provide warm steam to the wet type fish feed equipment extrusion part.

Richi machinery of the wet type equipment resembles that of the dry type fish feed extruder equipment. Yet the wet type requires adding water or vapor in the damp type fish feed equipment to enhance the wetness to twenty percent, or more than thirty percent during processing. It raises the temperature of the product by steam.

Working Principle Of Wet Type Fish Feed Extruder

The damp type fish feed maker contains screw, barrel, design template, fixture, etc. fish feed machine price as well as barrel are integrated in areas, and also the compression degree can be readjusted according to the type and requirements of the extruded feed, and also the growth degree of the extruded feed can be changed.


When the raw material enters the filling gadget, no added home heating is needed as well as the screw is pressurized at high pressure as well as high temperature to totally prepare and also disinfect the raw material.

During the high temperature curing procedure, the starch and fibers in the raw material increase. The product is after that molded right into pellets through the molding die under pressure-sealed conditions.


Finally, the high pressure generated by the routine turning of the screw is cut by the routine high-speed turning of the front cutter, and also the finished item is shrunk right into an average little puffed sphere at space temperature level and also stress.
