  • Publication number: 20030172663
    Abstract: A chiller includes a chilling compartment for receiving food products to be chilled and a chilling system for delivering chilled air to the chilling compartment during chilling operations. A controller effects operation of the chilling system and includes associated memory storing a plurality of food product data entries. Each food product data entry includes a food product name and at least one associated chilling operation setting for the food product. A user input device is associated with the controller. The controller is operable in conjunction with the user input device to permit a user to select a particular food product data entry such that the controller retrieves at least one chilling operation setting of the particular food product data entry for use in a subsequent chilling operation. The chiller may also include a label printing mechanism for printing chilling operation summary labels which can be applied to food product containers.

  • Patent number: 6311509
    Abstract: In a chiller, an apparatus and method for automatically identifying a temperature probe for use in a chilling operation is provided in order to reduce user error. In the place of manual selection by a user, automatic selection of the appropriate temperature probe is accomplished by comparing the temperature of the given temperature probe to a threshold temperature. An additional apparatus and method for filtering a displayed compartment temperature is provided to reduce user confusion. The responsiveness of the displayed temperature to temperature changes in the compartment is reduced when the compartment door is opened.

  • Patent number: 6092448
    Abstract: A food slicer for automatic operation having a staged dynamic brake for bringing the slicer carriage to rest at a predetermined location in a smooth manner. A sensor or system of sensors are utilized to detect the slicer carriage location. The sensor output is fed through a microprocessor which controls a dynamic brake which in turn acts upon the slicer carriage. The brake acts upon the carriage in two or more stages, so as to bring the carriage to rest in a smooth manner. The invention may also operate to as to bring the carriage to rest in a predetermined location.

  • Patent number: 5443655
    Abstract: A method for rinsing ware in a warewashing machine comprising the steps of: adding fresh rinse water to a wash chamber of the warewashing machine to rinse said ware in a rinse cycle; detecting the water level in the wash chamber; upon detecting a level below a predetermined volume, continuing to add rinse water to said chamber; and upon detecting a level of water equal to said predetermined volume, discontinuing the step of adding rinse water to said chamber.

  • Patent number: 5352866
    Abstract: An oil fryer control system simultaneously controlling oil temperature and cooking time. A proportional, integral and derivative temperature control is used to maintain the oil temperature below and above a predetermined set point temperature. In addition, a cooking time control varies the cooking time within a predetermined range of temperature error as a function of a stored time-temperature relationship. The invention provides the capability of cooking different products having different cooking parameters in the same or different oil vats.
