subject: New Invention Of Coating Machine [print this page] The object of the present invention is to propose a drying device for a coating machines, that allows to improve cleaning and/or maintenance operations, in particular as far as the drying air exhaust means are concerned.
The above mentioned objects are achieved by means of a drying device for a coating machines equipped with a rotary pan, in which the products to be coated are introduced, that includes air injecting means for supplying air to dry the products inside the rotary pan, and an exhaust air pipe equipped with perforated hollow head pieces which can be removed, adapted to be immersed in a heap of products to be coated.
Coating machines for pharmaceutical, confectionary and the like, are usually equipped with a rotary hollow drum, in which the products to be coated are introduced and sprayed with a liquid mixture aimed at forming the coating.Inside the rotary drum, also called coating machines, the products are subsequently exposed to a stream of hot air, so as to cause drying of the coating layer.
A drying device for a coating machines equipped with a rotary pan (1), in which the products to be coated are introduced, includes air injecting means (5) for supplying air to dry the products inside the rotary pan (1), and an exhaust air pipe (7), equipped with perforated hollow head pieces which can be removed, adapted to be immersed in a heap of products to be coated. The pipe (7) is supported by sliding means (21) which are moved in a direction longitudinal to the same pipe between a working position, in which the exhaust pipe (7) is operated, and an advanced position, so as to allow maintenance operation on the exhaust pipe (7) performed from outside through the front opening (3a) of the pan (1).coating machines
