Device for the coating of granulates and seeds
First Claim
1. A device for coating granulates and seeds, pellets and dragé
- es with one or more coatings, where the seeds to be coated are placed in a driven rotating drum, into which baffles fixed to the housing and spray and cleaning arms extend, the device comprising;
a drum;
an air supply connected to the drum by means of which the interior of the drum is subjected to an air stream;
air distribution in the drum being achieved by means of an air distribution plate fixed to a front side of the drum associated with an opposite non-rotating air distribution plate fixed to the housing, the non-rotating air distribution plate being configured such that it can move in axial direction towards and away from the drum and which can be connected with the drum by means of air;
the air distribution plate fixed to the drum and the non-rotating distribution plate forming a rotary distributor that is disposed at the rear of the drum;
at least a bottom portion of the drum positioned so that it can be disposed in a vat adapted to be filled with a cleaning fluid.

Abstract
A device for the coating of granulates and seeds, pellets and dragées with one or several coatings, whereby the seeds for coating are placed in a driven rotating drum, into which baffles fixed to the housing, in particular, spray and cleaning arms extend. Air supplies are connected to the drum by means of which the interior of the drum is subjected to an air stream. The air distribution in the drum is achieved by means of an air distribution plate fixed to the front side of the drum arranged opposite a non-rotating air distribution plate fixed to the housing, which is formed such that it may move in an axial direction towards and away from the drum and which may be connected to the drum by means of air. An improved cleaning of the housing and drum air feed is thus guaranteed.
