1.1 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.
1.2 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.
1.3 The soft serve/shake freezers 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,
1.3.6 Impact performance,
1.3.7 Idle energy rate, and
1.3.8 Heat treat cycle energy consumption (if applicable).
1.4 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.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
