ABSTRACT:
The present invention includes a first coating section, a second coating section and a device for transferring products from the first to the second sections. The first section includes a feeding and loading station for depositing products onto product holders retained in product carrier plates. The products are advanced to a first dipping station in the first section to coat a first portion of the product. The plates are then advanced to a first rotating station in the first station and rotated at least one revolution for spreading the coating over that first portion. The plates are then advanced to a dryer that extends over the first section of the coating apparatus and the coating is dried. The transfer device transfers the products to the second section of the coating apparatus in such a manner to expose the uncoated portion of the products. The plates are then advanced to identical dipping and rotating stations and dryer as in the first section. The plates are then advanced to an unloading and discharge apparatus for emptying the product from the product holders. The empty plates are then advanced to the transfer device where they are recycled for future use.
