Abstract: A food-zone system for preparing a food product, such as a chilled or at least partially frozen food product, includes at least one chamber assembly including a chamber with an interior configuration that defines a food passage extending therethrough with a cylindrical or tubular shape. The chamber is sealed along at least one end and includes an exterior wall configured as a refrigerated wall that includes an interior adapted to circulate coolant. A scraping tool operatively couples with the chamber and extends into the food passage. The scraping tool is configured such that an outer perimeter of the scraping tool contacts at least a portion of the interior configuration of the chamber. As the scraping tool moves through the food passage, the scraping tool removes or scrapes a food product mix disposed, preferably as a thin layer or coating, along at least a portion of the interior configuration of the chamber when the food product is chilled or at least partially frozen.
