Innovation - Pepper thresher

P K Ravi (Pepper thresher)
Kerala

As compared to other conventional threshers, Ravi's thresher can be operated both automatically and manually with higher output and minimal damage.

The Spices Board (Ministry of Commerce and Industry, Govt. of India) has recognised his innovation and included it in the Board's subsidy scheme.

About 100 kg pepper can be threshed in a one HP machine in ten minutes (60 kg in a HP version). It consumes 3/4 electric units per hour, has threshing efficiency 90 per cent and the damage is about 2-3 per cent.
