A method of coating seeds is provided using observations of coating and coated seeds to modify the coating of yet-to-be coated seeds. The supports 10, 11 of the first and second dancer rolls 8, 9 are hung into at least one hanger 12 that is guided over a deflection wheel 13, 14 and in this way so coupled together that the weight of the first and second dancer rolls 8, 9 is at least partially offset. The device further comprises a second zone with a second chamber that is not linked with the first section by way of a through opening that can be selectively opened.
