Abstract
A seed treater provides enhanced seed coating capabilities and performance. The seed and/or treatment fluid may be heated for improving vaporization and absorption by the seed. Air may be injected in the seed treater to provide heat, dehumidified air, and to provide vaporization enhancement, and component cleaning functions. The functions may be controlled by a control processor based on recipes and may be changed dependent upon sensed or input environmental conditions such as temperature and humidity.
Claims17
A seed treatment apparatus comprising:
- a seed treatment containment housing having an open interior for the treatment of seed with a treatment liquid, the containment housing having a seed inlet port, a seed outlet port, and an air inlet port defined by a top cover of the containment housing;
- a seed dispersion portion for distributing the seed in the open interior into an annular seed treatment region;
- a seed treatment liquid input line extending through the air inlet port into the containment housing and connected to a rotating liquid dispersion portion, the liquid dispersion portion comprising a rotating tray supported and positioned in the open interior of the containment housing, the seed treatment liquid input line being connected to the rotating liquid dispersion portion at a location such that the rotating tray generates a radially outward and annular spray of the treatment liquid into the seed treatment region;
- an air unit that takes ambient air and heats the ambient air to produce heated air;
- a seed storage reservoir and a heater associated with the seed storage reservoir for heating the seed prior to treating the seeds;
- and
- a duct connecting the air unit to the air inlet port defined by the top cover of the containment housing, the air inlet port being positioned such that the duct directs the heated air at the rotating tray of the liquid dispersion portion;
- wherein the seed treatment liquid input line extends through a portion of the duct connecting the air unit to the air inlet port so that the seed treatment liquid input line is contacted by the heated air before the seed treatment liquid input line extends through the air inlet port defined by the top cover of the containment housing.
