Abstract
A method of applying and distributing a charge of a particulate edible material onto a top surface of a substrate made of an edible dough product includes the steps of: (1) providing a charge of particulate edible material from an overhead hopper; (2) delivering the charge onto a movable vibrational surface having an area exceeding the area of the substrate, the surface being positioned above and in registration with the substrate; (3) keeping the charge on the vibrational surface within a specific area corresponding to the area of the substrate by the use of an encircling guide defining the specific area and having a lower end with a flexible skirt for contacting and sealing against the vibrational surface; (4) vibrating the vibrational surface for causing the charge received on the vibrational surface and kept within the specific area to be evenly and randomly distributed within the specific area; and (5) transferring the charge from the vibrational surface onto the substrate by moving the vibrational surface away from the position above and in registration with the substrate while vibrating the vibrational surface for allowing the charge evenly and randomly distributed within th…
