Low Drying Speed Floating Fish Feed Pellet Dryer Machine To Reduce Moisture To 10%

Fish feed dryer Introduction

After fish feed pellets are feeded evenly into the dryer, they will be spread on the dryer bottom by the rotatory spreader. The hot air of steam radiator will penetrate material layers and take the moisture away. Then dry pellets are pushed to the discharging hole by the screw pusher. Gas feed pellet dryer is commonly equipped with wet type fish feed machine, because wet fish feed machine need a boiler to provide steam, what you should do is to choose a larger boiler that can continuously send hot steam to feed extruder and pellets dryer.

Multilayer mesh belt structure: one circulation conveying belt, more than two heating machines, several fans, transmission device. The conveying belt is made of stainless steel wire mesh or multi-hole stainless steel plate.

Operation and Maintenance of Multilayer Mesh Belt Drying Machine

Head of the machine

The 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 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).

Drying section

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.

Dryer end

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.

Advantages of Mesh Belt Fish Feed Dryer

1. Materials will not vibrated or impacted during the drying process, so the pellets will keep intact.

2. Air quantity, heating temperature, materials staying time and feeding speed can be adjusted to achieve the best drying effect.

3. Simple structure, easy installation and maintenance.

4. Mostly used in requirement of low drying speed and long drying time.

5. Ideal for drying feed pellets, grains,etc. Due to the turn-over drying process, it cannot be used to dry viscous and fragile material.
