Mesh Belt Feed Pellet Dryer For Sufficient Uniform Drying Fish Feed

Fish feed dryer Introduction

Fish feed dryer is usually used in combination with fish feed cooler in the fish feed pellet line. 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 Fish 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.

When the pellets are discharged from the fish feed machine, the pellets temperature can be 90℃ and moisture about 18%. The temperature must be reduced quickly to ambient and moisture to 8%-12% for storage. In the whole fish feed production line, this dryer should be used after extrusion process via floating fish feed extruder. We can supply two types of feed pellets dryer, one is multilayer mesh belt dryer, the other is gas feed pellet dryer.

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. The equipment’s configuration is very flexible. Simple structure, easy installation and maintenance.

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

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

4. Hot air can be circularly applied, the energy is greatly saved.

5. Unique air dividing device, it makes hot air distribute uniformly; this can guarantee products’ quality.

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

7. Ideal for drying feed pellets, grains and etc.

8. It is commonly used in the low drying speed and long drying time of occasion.
