Abstract
A machine frame has a foraminous, inclined screen drum mounted for rotation thereon with an opening in one end which receives the peas for engagement by flat paddles attached in spaced relation to a horizontal, internal paddle shaft supported for rotation within the drum. A separating member supported on and rotating with the drum is spaced from the inside of the drum. The peas (kernels) fall through a closed housing to a shaker at the bottom and are collected in a pan. The hulls and trash are directed through the drum past the separating member and out of an opening at one end and into a trash bag. A blower on one end of the machine blows the trash through the housing. A drive means drives the drum and the paddles in opposite directions and also operates an eccentric to reciprocate the shaker.
