  • Ice cream machine including a controlled input to the freezing chamber
    Patent number: 7266952
    Abstract: An ice cream machine for cooling liquid ice cream into frozen ice cream includes an evaporator system with a secondary evaporator. The evaporator system includes a cooling chamber having an ice cream input and an ice cream output. A valve can be placed at the ice cream input to achieve dry freeze operation. The valve can prevent the cooling chamber from being completely filled.
    Type: Grant
    Filed: January 20, 2006
    Date of Patent: September 11, 2007

  • Ice cream machine including a secondary cooling loop
    Patent number: 6662592
    Abstract: An ice cream machine for cooling liquid ice cream into frozen ice cream includes an evaporator system with a secondary evaporator. The evaporator system can be a flooded evaporator or evaporator having an auxiliary tank or section of the evaporator that can ensure that a cooling chamber is surrounded by liquid refrigerant during normal operation. The secondary evaporator ensures consistent temperature within the evaporator during periods of low sales, hold modes, or non-production modes.
