| FEATURE INTRO – In this installment of Frugal Innovations, Tea Biz travels to Assam, India, to meet planter and mechanical engineer Ranjit Chaliha who describes the Varun, a device named after the Hindi God of Wind that recirculates heated exhaust to conserve energy and eliminate the inconsistencies in tea dryers that lower tea quality.

Achieving Consistency and Efficiency in Drying Tea – The Model Tea Factory at Tocklai was constructed during Ranjit Chaliha's tenure as chairman of the engineering subcommittee of India's Tea Research Association. During this time he began experimenting with equipment to recirculate exhaust in the factory's tea dryers. At an engineering symposium on tea machinery in 1998, Chaliha presented a paper describing the benefits of recirculating exhaust air. He based his findings on experiments and filed for a patent. A dozen years later, he was finally awarded recognition for his innovation, Varun, a device that reduces inconsistencies in drying tea.
