METHOD AND APPARATUS OF COATING ARTICLES

摘要

A coating such as liquid milk chocolate is applied to articles such as confectionery bars (12). The bars (12) are conveyed by conveyor (10) under a curtain (30) of liquid chocolate issuing through an outlet slot in the trough (14). A layer of air is caused to flow through the outlet slot in the trough (14) so as to modify the flow characteristics of the curtain. The layer of air permits a curtain (30) of even thickness to be achieved.
