Dry And Wet Floating Fish Feed Machine

Fish feed extruder

 

Fish feed extruders are commonly used to produce pelleted fish feed, which has become increasingly popular in recent years. According to the moisture content of the raw materials, fish feed extruders can be divided into dry and wet fish feed extruders to produce dry and wet fish feed pellets. Fish meal, fish oil, and vitamins are the main components of dry feed. Dry feed is made by extrusion and extrusion. Fishmeal, trash fish, vitamins, and binders are the main components of wet pelleted feed. Pelletized fish feed is suitable for freshwater and marine species.

 

The dry fish feed extruder machine

 

This floating fish feed extruder uses a screw extruder to extrude the raw material through the opening of the die, heating the object by friction. As the pellets leave the machine, their pressure, temperature and moisture content drop dramatically. The ingredients are then expanded to form porous particles. During operation, the moisture content varies between 15% and 20%. Single screw extruder is another name for dry fish feed pellet machine. The single-screw extruder works relatively smoothly and has strong shearing force, but the discharge port is easily blocked. Mainly used for processing raw materials, poultry and breeding feed. Manual disassembly and cleaning is required each time it is used. But when the raw material is extruded, the distribution of heat is not uniform. The curing uniformity is poor, the moisture content is low, and the scope of application is limited.

 

The wet fish feed extruder machine

 

The working principle of the wet type is similar to that of the dry type. But the former requires adding water or steam to the machine to increase the moisture to 20%, or more than 30% in the process. The purpose of the steam regulator: to increase the temperature of the material, soften and solidify the material, and replenish the moisture of the raw material.

The wet type fish feed pellet machine is equipped with a preparation device for maturing feed raw materials, and is usually used for mass production of feed lines. It can produce neat, uniform and beautiful ultra-small particle size particles, with good self-cleaning effect, no need to disassemble, maturity Good, high water content, wide application range, can produce high oil, high moisture materials, mainly used in aquafeed, pet food and animal feed.

 

The difference between dry and wet fish feed machine

 

1) Since the dry fish feed extruder does not need a steam boiler, the use and operation cost of the dry fish feed pellet machine is lower and the operation is simpler.

2) Compared with the dry extruder, the feed pellets produced by the wet fish feed pellet machine are smoother and of higher quality. This is because the material is matured and thoroughly mixed in the conditioner.

3) Dry type fish feed pellet machines usually have a smaller capacity than wet type fish feed pellet machines, so for small and medium farms or factories, it has better performance and is more cost-effective.

4) Wet extruders produce products with better shape than dry extruders due to better process control.
