  • Controlling temperature of a cryogenically refrigerated product
    Patent number: 4314451
    Abstract: The temperature of a product which is being chilled in a blender by introducing carbon dioxide in solid and gaseous form into the blender is controlled by sensing the power drawn by the drive motor coupled to the impeller. The power drawn by the motor is sensed and analyzed and, upon reaching a predetermined value, the introduction of CO.sub.2 into the blender is terminated. As the product is chilled by contact with CO.sub.2 in the blender, the viscosity of the product will increase, which in turn, increases the power drawn by the motor. Variations in line voltage supplied to the motor and changes of the initial temperature of the product being chilled do not affect the final temperature to which the product may be accurately chilled.
