Seed Decorticator

The manual depodding process presently followed is tedious, highly time and labour consuming. Currently castor seeds are manually depodded. After harvesting, the castor pods are sun dried for 3–12 days, depending on the initial moisture content and weather conditions. The husk is then removed from the seeds by beating with a mallet so as to release the seeds.
The depodding and decorticating efficiency was found to be 98.5 % at 6.22 % (wb) moisture content of the pods. At the same moisture content the capacity was also as high as 179 kgh. Overall dimension of the machine was 1255 x 625 x 1595 mm. Single person can conveniently operate the machine.
