【国外标准】 Standard Specification for Freezers, Ice Cream, Soft Serve, Shake

This specification covers the design, performance, and certification requirements pertinent to the construction of commercial ice cream, soft serve, and shake freezers that freeze and dispense frozen products (dairy, yogurt, custard, etc.) on a continuous basis. The ice cream freezers are classified into types according to frozen product produced, groups according to number of cylinders, styles according to mountability, classes according to condenser type, and grades freezing mechanism, as follows: Type I—soft-serve freezer; Type II—shake freezer; and Type III—combination soft-serve and shake freezer; Group 1—one freezing cylinder; Group 2—two freezing cylinders; Group 3—three freezing cylinders; and Group 4—four freezing cylinders; Style 1—floor mounted; and Style 2—countertop; Class 1—air-cooled condenser; Class 2—liquid-cooled condenser; and Class 3—remote air-cooled condenser; Grade 1—conventional nonheat-treatment freezer; and Grade 2—heat-treatment freezer. The freezers shall conform to electrical, steel fabrication, lubrication, interchangeability, refrigerant, insulation, and other performance and operational requirements, and should function satisfactorily as specified.1.1 This specification covers commercial ice cream, soft serve, and shake freezers, which freeze and dispense frozen product (dairy, yogurt, custard, etc.) on a continuous basis. Included in this specification are conventional and heat-treatment freezers.1.2 Equipment covered under this specification may contain a substance (or be manufactured with a substance) that harms public health and environment by destroying ozone in the upper atmosphere. This specification does not purport to address environmental regulations. It is the responsibility of the user of this standard to comply with environmental regulations (see 7.5).1.3 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.1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.
