Patent ID: 7906163

Claim:
In a system devoid of continuous belt conveyors, a method of applying a particulate coating to a food product including the steps of providing a conveyor of the differential impulse type that includes an horizontal pan driven in a cycle to move in a linear forward direction at one speed and in a linear rearward direction at a quicker speed such that in a portion of the cycle there is relative sliding motion between the pan and any material on the pan thereby to advance the material in the desired forward direction; providing on the horizontal pan a bed of particulate material for application to the food product as a bottom coating; placing the food product on the bed of particulate material and operating the conveyor in a plurality of cycles such that the product and the material move progressively in the forward direction to a transfer station; providing a top coating by supplying particulate material from above to the product and pan only during that portion of the cycle during which there is relative motion between the pan and the food product; retrieving from the pan and the product the excess material and recycling the material for reuse in the method.
