An apparatus for delivering an aerosol comestible coating towards a disc-like confectionary product, wherein said disc like confectionary has first and second major surfaces and a perimeter edge surface;
- said apparatus comprising a conveyor support surface, an electrostatic powder spray unit and an electrostatic coating discharge unit comprising an electrode and coating dispenser;
- wherein, in use, the conveyor support surface is arranged to provide a support to an edge surface of the confectionary product, the apparatus further comprising at least first and second guides, the guides together with the conveyor defining a channel, the guides either side of the disc-like products cause the disc-like products to be presented in a vertical orientation to the electrostatic field;
- wherein at least one of the conveyor or guides is oppositely charged relative to the electrostatic charge unit;
- whereby, in use, a single pass of the products though the apparatus is sufficient to enable a substantially uniform application of the electrostatically charged product to the first and second major surfaces of said disc-like product.
