A SYSTEM FOR GENERATING HOT AIR FOR TEA-LEAVES WITHERING TROUGH

摘要

: A SYSTEM FOR CONTROLLED HOT AIR GENERATION FOR TEA WITHERING USING LPG AS FUEL A system for generating hot air for withering green tea leaves in tea processing industry to drive away moisture from the leaves. The system make selective and beneficial use of L.P.G. as the fuel source in generating hot air for withering with very low consumption as compared to the conventional fuels like furnace oil, Coal, LDO, or HSD in similar application. A selective blower (BW) and burner (BR) combination used in the system adjacent the withering trough (WR) favour advantageous indirect firing of LPG to generate the hot air to achieve controlled flow of hot air into the withering fan (WF) and also the temperature by adjusting the speed of the hot air and further controlling the burner flames. The system is cost and energy saving , eco-friendly, pollution free without degrading tea quality and would favour wide scale application and use in withering process in tea industry. Fig:2
