Abstract

A breading machine has first and second combination battering/breading units positioned in close proximity to each other. Certain features of the invention have utility with machines having only a single battering/breading unit. Each of the combination units has a battering unit for applying a fluent batter to a food product. The battering unit includes a batter reservoir and a battering unit conveyor system for delivering food products from said batter reservoir to a battering unit conveyor discharge section that propels the food product from the battering unit. The combination units also include a breading unit for receiving food product from an associated battering unit. The breading unit includes a breading reservoir and breading unit conveyor system for applying particulate breading to the food product at a breading station by moving breading material from the breading material reservoir and food product coated with the batter to the breading station. A drive motor is coupled through respective first and second transmissions to provide motive power to the conveyors systems of each of the first and second combination battering/breading units for moving food products simultaneously through the combination battering/breading units.
