What Is Dry Type Fish Feed Extruder?

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

The dry type fish feed extruder is mainly utilized for the manufacturing of marine feed, such as making fish feed pellets, tilapia feed, catfish feed pellets, shrimp feed, crab feed, turtle feed, goldfish feed pellets, and so on. The finished pellet feed is extruded at high temperature with the home heating plate in the completely dry type fish feed machine.

Consequently, the finished granules can float on the water for concerning 24 hours as a result of being blown. Ended up 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 and so on approximately a larger 15mm. dry type machine heating the material by electric heating plate, this completely 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 pressure and temperature decline greatly, and the water vaporizes. The product is then increased into particles with a porous framework. During this process, dampness arrays from 15% to 20%.

when extrusion procedure, the material from the open end of the extrusion dental caries input, by the screw transport to the entire extrusion dental caries, and after that the supporting extrusion part right into a number of areas, in each location between the positioning of a ring (pressure ring) as the circulation and pressure control, the screw communicating activity to promote the material flow through the ring space in between the pressure ring and also the inside of the cavity, the mechanical energy generated by the rotational motion of the screw right into heat The friction in between the product as well as the parts of the completely dry type fish feed extruder machine and also the interior rubbing of the material.

As the product is squeezed out via the die hole at the end of the blowing cavity, the dough-like product is processed into a particular form, and as a result of the big propulsion of the screw in the blowing tooth cavity of the dry type fish feed device, a big stress is produced.

Developing in homemade chicken feed machine , when these materials are squeezed out from the die hole, a big amount of water in the material vaporizes immediately, which significantly decreases the wetness web content of the material.

What Is Wet Type Fish Feed Extruder?

Wet type fish feed extruder equipment is likewise commonly utilized to produce basic materials into state-of-the-art floating aquatic feed pellets, which is suitable for fish, catfish, shrimp, crab, feline, pet as well as various other family pets. The raw products utilized by the wet type fish feed maker are wheat, soybean, cake and also various other scraps, etc, as well as the puffed fragments produced by the damp type fish feed extruder device can drift on the water surface for greater than 24-hour without liquifying.

Wet type feed extruder equipment are generally utilized in large as well as medium-sized feed handling plants and also ranches. it works with the steam boiler, the boiler continuously can provide warm steam to the wet type fish feed machine extrusion part.

The functioning principle of the wet type device is similar to that of the completely dry type fish feed extruder device. But the wet type calls for adding water or vapor in the damp type fish feed machine to raise the dampness to twenty percent, or greater than thirty percent during handling. It raises the temperature of the product by steam.


Functioning Principle Of Wet Type Fish Feed Extruder

the wet type fish feed maker contains screw, barrel, template, component, and so on. The screw and also barrel are integrated in areas, and the compression level can be changed according to the type and demands of the extruded feed, as well as the growth level of the extruded feed can be changed.

When small fish feed machine gets in the loading device, no added heating is required and the screw is pressurized at high pressure and also heat to totally cook and also disinfect the raw product.

During the high temperature healing process, the starch and fibers in the raw product expand. The material is then built right into pellets through the molding die under pressure-sealed problems.

Lastly, the high pressure generated by the routine turning of the screw is cut by the regular high-speed rotation of the front cutter, and also the completed item is shrunk right into an average little puffed ball at room temperature and stress.
