**6.1 Tamarind dehuller**

A dehuller for tamarind was developed at Tamil Nadu Agricultural University (TNAU), Coimbatore, India (**Figures 7** and **8**). It has a capacity of 100 kg/h with dehulling productivity of 94%. The impact force and sieve shaking mechanism were used to develop the Tamarind dehuller. The impact force from the rotating beaters was applied to the dried tamarind fruit fed through the feed hopper. The outlet received the dehulled, un-hulled, and hulled fruits. The system includes sharp "L" shaped pegs made up of 15 � 3 mm size gentle steel level mounted on the focal shaft that encased with 20 � 5 mm mild steel oblong sieve [7].
