Final pellets from fish feed extruder or flat die pellet mill are moist in high temperature, so they can not be transported and stored immediately and require to be dried first. Mesh belt pellet dryer machine is specially designed machine to remove pellet moisture and heat generated in pellet production. Pellet drying process is: placing the material on the conveyor belt with the accompanying motion by contact with hot air in the tunnel to drying.
Uniform pellet drying, flexible configuration and unique air dividing device, mesh belt dryer machine are offered with three models for your drying demands!feed pellet dryer machine is usually used in combination with feed pellet in the feed production plant. Fish feed pellets are transported from fish feed extruder to the pellet dryer machine, then being conveyed on the mesh belt which is made of stainless steel.
Speaking of the mesh belt, it is with multi-layer structure and movable, which makes our dryer fast-drying & high-efficiency, so the dryer machine is also called Mesh-belt Type Pellet Feed Dryer. This pellet dryer machine is widely applied in chemical, food, medicine, building materials, electronics and other industries, specially applicable to dry granular materials and pellets.
Operation and Maintenance of Feed Pellet Dryer Machine
Head of the machine
The feed pellet drying machine head 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 (because of the thermal expansion).
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.
The transmission part is installed in the end of the fish feed pellet dryer. 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.
How does Feed Pellet Dryer Machine Work?
This belt feed pellet drying machine is composed of several independent units. Each unit consists of circulating fan, heating device, separate or common fresh air suction system and exhaust system. The operating parameter of each unit is controlled independently, ensuring reliable and optimized operation.
The feeder distributes the feed pellets evenly on the top layer of belt conveyor, which is made by stainless steel wire mesh or perforated plate. The pellets move along with the belt conveyor and falls gradually on the lower layer. Hot air passes through the pellets and brings away the moisture. Finally the pellets are discharged through the outlet.
