ASTM F2795-11

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

1.2 This test method applies to the following types of soft serve and shake machines: (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.

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

1.3.1 Maximum power input, or maximum current draw,

1.3.2 Initial freeze-down energy consumption and duration,

1.3.3 Heavy-use energy consumption,

1.3.4 Production capacity,

1.3.5 Overrun,

1.3.6 Impact performance,

1.3.7 Idle energy rate, and

1.3.8 Heat treat cycle energy consumption (if applicable).

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
