Abstract

An automated food processing system and method is provided that allows food to be dispensed, fried and packaged in a suitable container, which may be an individual portion-sized container. In one embodiment, the system includes separate automated modules for dispensing, frying and packaging the food. In one embodiment, an automated dispensing device dispenses a predetermined portion of food from a bulk storage container or food dispensing magazine. Food is dispensed from the automated dispensing device to an automated fry device that can include at least one circular fry wheel having a plurality of food containing compartments. After the food is fried it is dispensed from the fry device to an automated packaging device. The automated packaging device dispenses food to a container that may be an individual portion-sized container that is retrieved, erected and held into position for filling by an automated container handling system. After a food container is filled, a conveyor system transports the filled container to a suitable pick-up location.
