PROCESS AND APPARATUS FOR APPLYING PESTICIDES TO GRANULAR MATERIALS

摘要

A process for applying a pesticidal composition to granular vegetative products such as grains and seeds, which comprises: (1) loading and compacting a granular material into a first chamber by conveying it upwardly against the force of gravity; (2) conveying and tumbling the compacted granular material from the first chamber into a second chamber of greater capacity than the first chamber to permit mixing and tumbling of the granular material; (3) spraying the tumbling granular material with a pestidical composition in the second chamber; and (4) discharging the sprayed granular material from the second chamber. Apparatus suitable for carrying out the process of the invention are also described.
