BELT DRYER BD-2000 has three conveying belts where the first and the second have been designed for drying and the third one has been constructed to cool the product down.
The movement of the product and the circulating air goes in the opposite direction to each other.
ADVANTAGES
- adjustment of variable belt speeds
- uniform pellets feeding and spreading over the belts
- gentle and homogeneous drying
- reliable construction
- parts that contact the feed pellet are made in food-grade stainless steel
SEQUENCE OF OPERATION
BELT DRYER BD-2000 is usually integrated into pet food lines and the complete lines for aquafeed production.
It ensures efficient, gentle and homogeneous drying of feed pellets and guarantees the quality of the final product.
How the product moves
Feed pellets are continuously fed and evenly spread on the first conveying belt. At the end of the top belt, the product transfers to the second belt.
After going through the drying process, the product gets on the third conveying belt where the process of cooling takes place.
There is a built-in cooler allows the product to be cooled to the temperature which is higher than the ambient temperature by 10 °С.
Fine layers with adjustable speeds offer the uniform distribution of the product. The speed of the belts, drying temperature, air and exhaust flow is controlled for each drying section.
How the air flows
The air with the help of pressure fan moves through the third conveying belt.
Afterward, with the help of 4 air heaters, the air is heated and is evenly drawn through the two layers of the product with 4 hot air exhaust fans.
The temperatures inside the dryer chambers are constantly monitored, these measurements automatically control the speed of the belt and this gives the most efficient drying time and consistent quality of product
1) feed pellets are continuously fed to the top conveying belt of the drying section
belt area – 24,5 m2
belt speed – adjustable
height of the product layer – up to 110 mm
2) feed pellets are transported to the second lower conveying belt
belt area – 24,5 m2
belt speed – adjustable
3) heated air constantly circulates through the conveying belts
the amount of air is regulated by the pressure fan (15 kW) and 4 hot air exhaust fans (2,2 kW each)
the temperature of the drying process and heat volume are adjusted for each drying section
4) the already dried pellets are moved to the cooling section
belt area – 24,5 m2
belt speed – adjustable
the temperature of the discharged pellets is higher than the temperature in the shop by 5 … 10 °С
QUALITY ASSURANCE
Warranty period – 1 year
- certified production ISO 9001:2015
- Our BELT DRYER are designed for continuous and trouble-free operation.
In the upper part, there are two drying layers (conveying belts) / In the bottom, there is one cooling layer (conveying belt)
