Screw Feeder Hopper for Feeding of Tea

The Screw feeder hopper is a screw bulk material handling system used to transport raw materials to and from processing areas located at different levels of the facility. These conveyors are inclined at different angles to economically lift and convey material up and down the floor. They require enough space and more power to lift the material, depending on the steepness of the angle, and can be used with packaging machines.

Task

Careful handling of fragile tea leaves throughout the entire processing chain: product feeding, tea washing (screening, grading, de-gritting), blending, storage, packing machine feeding for consistent product quality

Solution

1. Unprocessed tea leaves are usually packaged in large bags and need to be fed into a closed system. Dahan Machinery has developed a special-purpose feed hopper for this purpose. It can be fed from both sides at the bag loading and unloading station if necessary.

2. If the raw material is delivered in big bags, a simpler unloading station can be used.

3. The raw materials for making the tea mixture are conveyed to the mixer very carefully and with high precision using a pneumatic vacuum weighing system.
