The present invention relates to an improved apparatus 30 and method for delivering a coating substance such as a powder, liquid, or suspension coating. The article to be coated is preferably a snack food such as potato crisps or corn chips which are usually coated with flavouring. It is generally desirable to be able to achieve a uniform and controllable coating over the entire surface of a product. The apparatus comprises two enclosed coating stations 33, 34 connected by a conveyor 39 and a flipping or inverting device between the two enclosures. The flipping device may be a drop between conveyors, a cascade system (figure 3a) or a plough share like flipper or curvilinear plate (figure 3b). The inversion of the article between the two coating enclosures ensures even coating on both sides of the article. |
