ABSTRACT:
A seed treating machine for the separation of seeds from lighter-weight particulant plant matter intermixed with the seeds. The seed separating machine includes a horizontally mounted table having a center opening under which a plurality of fans are mounted to provide an upward blast of air. A screen is affixed to the table over the center opening and a harvested mixture such as seeds and particulant plant matter are placed on top of the screen. The blast of air lifts the lighter particulant matter away from the heavier-weight seeds. A semicircular cover is affixed to the table covering the screen to contain the seeds. The lighter-weight material is released to the atmosphere. The table is pivotally mounted upon an upright stand, permitting the table to be tilted from side-to-side to fully expose the mixture to the air blast. The separated seeds roll down the table through a chute and into a container for packaging.
