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.
Claims21
An ice cream making system, comprising:
- an evaporator including a cooling chamber, the cooling chamber having an ice cream input and an ice cream output;
- and
- at least one valve at the ice cream input, the valve being capable of preventing ice cream from entering the cooling chamber.
An evaporator for an ice cream making system, the evaporator comprising:
- an interior surface defining a cooling chamber for chilling a product, the cooling chamber having an ice cream input and an ice cream output;
- an evaporator chamber surrounding the cooling chamber;
- and
- a valve in series with the ice cream input.
A method of manufacturing ice cream, the method utilizing an ice cream machine having a cooling chamber, the method comprising:
- providing liquid ice cream contents into the cooling chamber through a valve, the valve preventing the cooling chamber from being more than 75 percent filled during a hold mode;
- cooling the liquid ice cream contents in the cooling chamber;
- and
- removing frozen ice cream from the cooling chamber.
An ice cream making system, comprising:
- an evaporator including a cooling chamber, the cooling chamber having an ice cream input and an ice cream output;
- and
- a means for restricting access through the ice cream input to the cooling chamber.
