Abstract: A food products chiller and method of using the same as provided. The chiller includes a container for receiving and holding the food product, a cooling station for cooling liquid coolant, an ultraviolet radiation station for reducing the microbial contaminants in the coolant, and a circulation system for circulating the coolant from the cooling station to the container, from the container to the ultraviolet radiation station, and from the ultraviolet radiation station to the cooling station for reintroduction into the container for cooling additional food products. In the chilling method, the food products are chilled by exposure to the coolant liquid as the drum rotates. The liquid is drained from the drum, filtered and subjected to ultraviolet radiation so as to kill the microbial contaminants in the coolant. The coolant is then recirculated to the cooling station for re-cooling and re-introduction into the drum for chilling additional food products.
