Tea Industry Fans
We have been supplying Withering Fans to various Tea companies all over India for more than 15 years. WITHERING is the first and foremost step involved in tea manufacture. Withering is the process of removal of moisture from green tea leaves by blowing hot air over the leaves in a withering trough. The current of air performs two functions – 1) Conveyance of hot air to promote evaporation and 2) Carrying away the water vapour through a bed of green leaves.
Considering the above need and operating condition, we developed a series of Fans which are best suited for the Tea Industry.
