Dry Type Vs Wet Type Fish Feed Extruder

What Is Dry Type Fish Feed Extruder?


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

2nd hand pellet machine is mainly 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 finished pellet feed is squeezed out at heat via the home heating plate in the dry type fish feed machine.

Therefore, the ended up granules can float on the water for about 1 day as a result of being puffed. Completed sawdust pellet press machine 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 equipment heating the material by electric home heating plate, this dry type machnine squeezes out the material from the holes of the die under the action of the screw extruder.

When the pellets come out of the maker, the pressure as well as temperature decline dramatically, and also the water vaporizes. biomass pellet mill for sale is after that expanded into particles with a porous structure. Throughout this process, moisture ranges from 15% to 20%.

Functioning Concept Of Dry Type Fish Feed Extruder

When extrusion procedure, the material from the open end of the extrusion cavity input, by the screw transportation to the whole extrusion dental caries, and afterwards the complementary extrusion part right into a number of areas, in each area in between the positioning of a ring (stress ring) as the flow as well as pressure control, the screw communicating action to promote the product flow via the ring space in between the stress ring as well as the inside of the cavity, the mechanical energy created by the rotational motion of the screw into warm The friction in between the product and also the parts of the dry type fish feed extruder equipment and also the interior rubbing of the material.

As the product is squeezed out through the die hole at the end of the blowing dental caries, the dough-like material is refined into a specific form, as well as because of the substantial propulsion of the screw in the puffing tooth cavity of the dry type fish feed machine, a big pressure is created.

Developing in the material, when these materials are squeezed out from the die hole, a huge amount of water in the product evaporates instantly, which considerably reduces the wetness web content of the product.

What Is Wet Type Fish Feed Extruder?

Wet type fish feed extruder machine is additionally extensively made use of to produce raw materials right into top-quality floating aquatic feed pellets, which is suitable for fish, catfish, shrimp, crab, pet cat, dog as well as other pet dogs. The raw materials made use of by the damp type fish feed machine are wheat, soybean, cake and various other scraps, and so on, and also the puffed bits generated by the damp type fish feed extruder maker can float on the water surface for greater than 24 hr without dissolving.

Wet type feed extruder equipment are generally made use of in huge and medium-sized feed processing plants and also farms. it works with the vapor central heating boiler, the boiler continually can supply warm vapor to the wet type fish feed maker extrusion part.

The functioning principle of the damp type machine is similar to that of the dry type fish feed extruder machine. But the damp type calls for adding water or steam in the damp type fish feed machine to enhance the moisture to twenty percent, or more than thirty percent throughout handling. It raises the temperature of the material by vapor.

Working Concept Of Wet Type Fish Feed Extruder

The damp type fish feed machine contains screw, barrel, design template, component, etc. The screw and barrel are incorporated in sections, and the compression level can be readjusted according to the type and requirements of the extruded feed, as well as the expansion level of the extruded feed can be transformed.

When the raw product goes into the filling up tool, no extra heating is required as well as the screw is pressurized at high pressure and also high temperature to fully prepare and also disinfect the raw material.

Throughout the heat treating procedure, the starch and also fibers in the raw material broaden. The material is then molded into pellets with the molding die under pressure-sealed conditions.

Ultimately, the high pressure produced by the routine rotation of the screw is reduced by the routine high-speed rotation of the front cutter, as well as the finished item is shrunk into an ordinary small puffed sphere at area temperature and also pressure.
