Abstract
A seed coating machine comprising an upper mixing drum wherein a liquid adhesive coating is applied to seed and where the rate of application is regulated by a valve controlled by the seed feeder. Coated seed is dried to a state of tackiness and passed to a second, lower mixing drum. A variety of powders are applied onto the tacky seed after being mixed and sifted in a screen distributor. The resulting coated seed has an outer powder layer which adheres to the inner adhesive coating.
