Abstract
A stream of seed may be maintained at a metered flow rate through multiple stages of a treatment process. These multiple stages include dispensing, first application of fluid, second application of fluid, and seed transport. Seed transport may be accomplished through a conveyor configured to maintain the metered flow rate while providing static mixing, drying, and conditioning of the treated seed. The metered stream of seed may be treated within a first treatment applicator where a first wet treatment is applied, transferred through the incline conveyor, and treated again within a second treatment applicator where a second wet treatment is applied. Overtreating in multiple stages may layer consecutive seed treatments around the treated seed. A predetermined amount of seed treatment may be applied to the coated seed based on the metered flow rate established. Maintaining the metered flow rate through multiple stages eliminates the need for multiple metering steps.
