Standard Test Method for Performance of Self-Contained Soft Serve and Shake Freezers
 N F2795

Annotation

This test method evaluates the energy consumption and performance of soft serve ice cream and shake freezers. The food service operator can use this test to evaluate and select an appropriate soft serve or shake freezer and understand its energy consumption and production capabilities.

This test method applies to the following types of soft serve and shake freezers: (any of which may or may not have a reservoir for liquid mix). Included in these test methods are conventional and heat-treatment freezers. The unit may include separate refrigeration systems for the frozen product and fresh mix and may be either air-cooled or water-cooled.

The soft serve/shake freezers will be tested for the following (where applicable):

Maximum power input, or maximum current draw,

Initial freeze-down energy consumption and duration,

Heavy-use energy consumption,

Production capacity,

Overrun,

Impact performance,

Idle energy rate, and

Heat treat cycle energy consumption (if applicable).

The values stated in inch-pound units are to be regarded as standard.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
