Abstract
Apparatus whereby seeds, in particular unginned cottonseeds having lint, may be wetted with liquid active ingredients. To achieve this, the cottonseeds are separated in a feeder and metering device having conveyor screws and a baffle, and fitted uniformly into a spray chamber. In the spray chamber an atomizer produces a fine spray mist and wets the dropping seed grains. The grains drop into a mixing and transport chamber wherein they are mixed by mixer and agitator shafts. A conveyor screw transports the seed during the mixing slowly toward an inlet opening.

Apparatus for the wetting of seeds with active ingredients dissolved in a liquid, said apparatus comprising:
- a feeder and metering device, an opening of which is directed from above into a spray chamber having an open bottom, the feeder and metering device including an essentially horizontal screw conveyor with at least two mutually cooperating conveyor screws and a baffle extending into a portion of a space between said screws, the conveyor screws having turns with a depth of an order of magnitude of the seed grains to be treated;
- and an atomizer for a liquid active ingredient, said atomizer being located in the bottom of the spray chamber, the atomizer generating a particle size of less than 300 .mu.m;
- and a mixing and discharge means located under the spray chamber, the mixing and discharge means including at least one conveyor screw and at least one mixer shaft located parallel to said mixing and discharge means conveyor screw, said at least one mixer shaft being equipped with agitator paddles.
