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.

What is claimed is: 1. A direct draw 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 compressor, the compressor having a horse power rating of less than 3 horse power; at least one valve at the ice cream input, the valve being capable of preventing ice cream mix from entering the cooling chamber, wherein the valve controls the ice cream mix so that the cooling chamber is filled with the ice cream mix so that the ice cream mix becomes frozen ice cream from the time it travels from the ice cream input to the ice cream output, wherein the valve is controlled to prevent the cooling chamber from being more than 50 percent filled. 2. The ice cream making system of claim 1, wherein the valve is controlled to maintain the cooling chamber filed to 25-50 percent. 3. The ice cream making system of claim 1, further comprising a gate at the ice cream output, wherein the valve and the gate are operably linked to open and close in coordination. 4. The ice cream making system of claim 1, further comprising a gate at the ice cream output, wherein the gate and the valve are controlled so that the valve is opened when the gate is opened. 5. The ice cream making system of claim 4, wherein input valve is maintained opened after the gate is opened until an appropriate level of product is achieved in the cooling chamber. 6. The ice cream making system of claim 1, wherein the evaporator includes a primary evaporator chamber and a secondary evaporator chamber, the primary evaporator chamber being provided about the cooling chamber and the secondary evaporator chamber being provided about the primary evaporator chamber. 7. A direct draw 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 compressor, the compressor having a horse power rating of less than 3 horse power; at least one valve at the ice cream input, the valve being capable of preventing ice cream mix from entering the cooling chamber, wherein the valve controls the ice cream mix so that the cooling chamber is filled with the ice cream mix so that the ice cream mix becomes frozen ice cream from the time it travels from the ice cream input to the ice cream output, wherein the evaporator further includes a primary evaporator chamber about the interior cooling chamber and a copper tube provided about the primary evaporator chamber, the copper tube having a first end associated with the second refrigerant input and a second end associated with the second refrigerant output. 8. A direct draw ice cream making system, the direct draw ice cream making system comprising: an evaporator including an interior surface and an evaporator chamber, the interior surface defining a cooling chamber for chilling a product, the cooling chamber having an ice cream input and an ice cream output, the evaporator chamber being an evaporator chamber surrounding the cooling chamber; a valve in series with the ice cream input; a gate at the ice cream output, wherein the valve is closed in a non-production mode and opened when the gate is opened; and a secondary evaporator for collecting vapor refrigerant exiting the evaporator chamber, wherein the cooling chamber is defined by a first cylinder and the evaporator chamber is defined by a space between the first cylinder and a second cylinder, the second cylinder being about the first cylinder. 9. The system of claim 8, wherein the secondary evaporator is a copper tube. 10. The system of claim 9, wherein the valve is a metering valve. 11. The system of claim 8, wherein the secondary evaporator is a chamber defined by the second cylinder and a third cylinder, the third cylinder being about the second cylinder. 12. The system of claim 8, wherein the secondary evaporator is in the form of a secondary evaporator tank coupled to the evaporator chamber. 13. A method of manufacturing ice cream in a direct draw fashion, 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 cooling chamber being a barrel chamber surrounded by an evaporator, 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, wherein valve prevents the cooling chamber from being more than 50 percent filled. 14. The method of claim 13 wherein the hold mode is a period of low sales of the frozen ice cream. 15. The method of claim 13 wherein the frozen ice cream is removed through a gate, the gate being opened and closed in coordination with the valve allowing liquid ice cream contents into the cooling chamber. 16. The method of claim 13, further comprising a secondary evaporator, wherein the secondary evaporator surrounds the evaporator chamber.
