Abstract

A continuously provided ground food product (e.g. meat) is leveled to a particular thickness and then irradiated. The leveler may be formed from two (2) spaced members (e.g., closed loop belts) spaced from each other by a distance progressively decreasing to a distance corresponding to the particular thickness. This distance may be adjustable to define any desired thickness for the food product. The leveler and the radiation source are disposed in a chamber providing shielding against radiation. The belt carrying the food product past the radiation source deposits the irradiated food product in a receptacle. A transport mechanism (e.g. auger) transports the irradiated food product, without exposing the food product to harmful bacteria, from the receptacle to a former which provides the food product in individual configurations (e.g. hamburgers, chubs and case ready) without exposing the product to harmful bacteria. The formed product is thereafter stored in an environment which excludes harmful bacteria. The belt carrying the food product may be reversed in direction when the radiation from the source is interrupted. The food products are then deposited in a second receptacle and a…
