Method and means for uniformly coating particulate material |
摘要 |
An apparatus is provided for uniformly coating particulate material. The apparatus includes a frame, a cylindrical drum rotatable about an axis tilted with respect to a horizontal plane, and a spray nozzle extending into the drum so as to spray a coating solution onto the particulate material tumbled within the rotating drum. Perforations in the side wall of the drum allow a flow of air through the drum so as to dry the material within the drum as it is coated with solution. A vacuum system removes the coated seeds from the drum without manual handling. In operation, the seeds form a dense mass, and migrate away from the mass as the seeds increase in size and weight from the sprayed coating. Eventually, all of the particles are uniformly coated, and thus a new mass is formed and the process repeated until the material reaches a desired size.
