Study on effecting parameters of fresh sweet corn shelling without cutting corn germ

บทคัดย่อ

Fresh sweet corn shelling machine was designed and assembled to study the parameters effect on shelling of Hybrix 10 variety without cutting corn germ. The shelling process is divided into two parts; using grooving sets for gouging fresh sweet corn and shelling machine for kernels shelling. This machine can operate 1 corn each time and require 2 operators. The main part of the grooving set is open groove roller and the grooving knife. The
operation begins as groove roller will cut open groove of kernels to help remove easier with the width of the slit about 2 cm whereas the grooving knife will slash the kernels out. Moreover, the main of shelling machine is the shelling set operated to move alternation and pushes the kernels out of the core. The parameters were studied follow by 1) type of shelling rubber; type I and type II, 2) angle of shelling; 36°, 42° and 48° respectively, and 3)
speed of shelling rubber revolution; 40, 50 and 60 rpm respectively. From this experiment showed that the shelling rubber type II gave the better shelling result than shelling rubber type I. The result from shelling rubber type II, angle 36° with speed at 60 rpm had an average of kernels damage at 10.02%. The time and power consumption were used for shelling had averages of 251.94 s/ears and 14.03 W/ears respectively.
