VIBRO FLUID BED DRIER works on the principle of 'vibrating fluidized bed'. It works on pneumatic and mechanical power. The fermented teas are fed through a feed system into the drying chamber. Hot air from the heater is passed from underneath to the drying chamber through the perforated tray carrying wet teas. The tea leaf is effectively fluidised by a combination of air pressure and mechanical vibration.

COMBINATION DRIER Tempest drier is a combination of conventional and fluid bed drier. In the tempest drier on top of the drying chamber i.e., above the fluidisation zone there is a tray moving inside which carries the fermented leaf from the drum where surface moisture is removed by exhaust temperature. Since a certain percentage of moisture is removed from the leaf before entering into the fluidisation zone, the output of the drier is higher than conventional FBD.

FIBRE EXTRACTOR This works on the principles of static electricity. There are 4 to 6 PVC rollers arranged in a row. The PVC rollers brushes against thick pads of felt which imparts a static electricity to developed on the PVC rollers. When tea is fed in to this machine after firing, frictional force takes place between fibre and the rollers. As a result static electricity is produced. The PVC rollers act as positive charge (+)and fibre acts as a negative charge (-), thereby both attract each other and fibre is collected from the PVC rolle

SORTER is a simple machine which is used to grade the bulk tea from the fibre extractor into different grades according to their size. Generally the sorter is fitted with meshes of different size.
