Introduction to Fish Feed Pellet Dryer
Final pellets from fish feed machine has high moisture and high temperature, so they can not be transported and stored immediately and require to be dried at first. mesh type fish feed dryer machine is a specially designed pellet dryer machine to dry finished fish feed pellets moisture and heating generated in fish feed production. fish feed dryer is usually used in combination with fish feed cooler in the fish feed plant.
Final finished fish feed pellets are conveyed from fish feed machine to the fish pellet drying machine, then being conveyed on the mesh belt which is made of stainless steel. This floating fish feed pellet drying machine is widely applied in fish feed factory, pet food factory, poultry feed factory, and other industries, which is specially applicable to dry granular materials and pellets.

Working Principle of Fish Feed Pellet Dryer
Feed pellet dryer consists of several independent units. Every unit is made up of circulation air blower, heating device, fresh air suction & exhaust discharging system. The repeating conveyor belt is made of a stainless steel wire mesh or perforated stainless steel plate, driven by the electric motor via gearboxes. The drying process is carried out in a fully-sealed box, effectively avoiding dust leakage.
Damp materials are evenly spread on the mesh belt which is driven to move by transmission device in the dryer machine. From bottom to top, hot air flow through the mesh belt and fish feed pellets on it. In the drying process, heat exchange is sufficient & uniform, drying efficiency being extremely high. The mesh belt is made of 12-60 mesh stainless steel wire mesh and is moved by the transmission device to move inside the fish feed drying machine.
The drying section is composed of several units, and each unit is independently circulated by hot air. Some of the exhaust gas is discharged by a special exhausting fan, and the exhaust gas volume of each unit is controlled by a regulating valve. In the upper circulation unit, the wind from the circulating fan enters the lower chamber of the unit from the side air passage, and the air flow is heated upward through the heat exchanger and distributed by the distributor.
The jet is blown toward the mesh belt and passes through the material and enters the upper chamber. The upper chamber is connected to the fan inlet by the air duct, and most of the gas fluid is circulated, and a part of the gas having a relatively low temperature and a large moisture content is discharged as exhaust gas through the exhaust pipe, the regulating valve, and the diving fan.
In the lower circulation unit, the wind from the circulating fan first enters the upper chamber, is heated downward through the heat exchanger, passes through the material layer and enters the lower chamber, and the lower chamber is connected to the fan inlet by the side air passage and the return air duct, and most of the gas circulation Part of it is discharged. The upper and lower circulation units can be flexibly equipped according to user needs, and the number of units can also be selected according to needs.
Advantages of Fish Feed Pellet Dryer Machine
- Materials will not vibrated or impacted during the drying process, so the pellets will keep intact.
- Air quantity, heating temperature, materials staying time and feeding speed can be adjusted to achieve the best drying effect.
- the floating fish feed dryer machine has simple structure, easy installation and maintenance.
- this fish feed dryer machine mostly used in requirement of low drying speed and long drying time.
- Ideal for drying feed pellets, grains,etc. Due to the turn-over drying process, it cannot be used to dry viscous and fragile material.
- Hot air can be circularly applied, the energy is greatly saved.
- Unique air dividing device, it makes hot air distribute uniformly; this can guarantee products’ quality.
Maintenance of the Fish Feed Dryer Machine
the head of the fish feed dryer
The head of fish feed dryer machine is composed of two driven rollers, tightener, feed inlet and outlet. Passive bearing bears the tension and determines the tightness of the mesh belt, so bearings at both ends of the passive rollers should be regularly lubricated with high temperature (above 200℃) lubricating grease, to ensure the normal operation of the feed pellet dryer. Tightener is to adjust the mesh belt tightness. The first installation, mesh belt should be tightened, and after heating up, tightening again
the end of the feed pellet dryer
The transmission part is installed in the end of the fish feed pellet drying machine. The tightness of the transmission chain can be adjusted by adjusting the position of the gear reducer. Transmitting gear on the other side of the gear reducer will also inject lubricating oil to extend its service life.
the section of the fish feed dryer
This stage is the actual working area of material drying, blast pipe and discharge pipe being installed on the top. Hot air flows into the underpart of the inner chamber from both sides, then extracted out by wind turbine from the middle. There are control valves being installed on the air inlet and outlet to adjust air velocity.
