Abstract
Two types of baby corn silk detachment systems called fixing and moving baby corn and based on applying frictional force on the silk were developed and evaluated. In the fixing mode the baby corn was fixed on a pin and a hollow frictional cylinder was moved concentrically and vertically along the baby corn towards the branch end. In the moving mode the baby corn was forced vertically towards the tip to pass through the same silk detachment cylinder. Traveling speeds of the detachment cylinder and the baby corn were 44.5 and 166.9 mm/s. In the fixing mode at silk moisture content of 91 % (w.b) silk detachment efficiencies at low and high speeds were 99.1 and 99.2%. The silk detachment efficiencies in the moving mode at low and high speeds were 96.6 and 98.5%. Damaged baby corn at low speed was less than at high speed in both modes. Minimum damage was nil in the fixing mode at low speed and the maximum was 47.5% in the moving mode at high speed. The damaged was due to ovaries r moval at the base near the joint between the baby corn and the branch.
