27、erformance of dispensing freezers and their related components. 1.2 Scope This Standard contains requirements for the following equipment: dispensing freezers that process and freeze previously pasteurized product (e.g., soft ice cream, ice milk, yogurt, malts, custards) and dispense it directly int

28、o the consumers container; dispensing freezers that dispense premanufactured frozen product (e.g., ice cream) directly into the consumers container; and batch dispensing freezers. The materials, design, and construction requirements of this Standard may also apply to items that are manufactured as a

29、 component of a dispensing freezer. Dispensing freezer components and materials covered under other NSF or NSF/ANSI Standards or criteria shall also comply with the requirements therein. This Standard is not intended to restrict new unit design, provided that such design meets the minimum specificat

30、ions described herein. 1.3 Alternate materials, design, and construction While specific materials, design, and construction may be stipulated in this Standard, dispensing freezers that incorporate alternate materials, design, or construction may be acceptable when such equipment meets the intent of

31、the applicable requirements herein. 1.4 Measurement Decimal and SI conversions provided parenthetically shall be considered equivalent. Metric conversions and significant figure rounding have been made according to IEEE/ASTM SI 10. 2 Normative references The following documents contain provisions th

42、bris, and to permit the inspection, maintenance, servicing, and cleaning of the equipment and its components. Product reservoirs and freezing chambers shall be protected so as to prevent the entry of vermin, dirt, debris, splashes, and spills. 5.1.2 Dispensing freezers shall be designed and manufact

43、ured so that food, product mix, and ingredients may be added, processed, finished, dispensed, removed, and/or served in a sanitary manner. 5.1.3 Food zones shall be readily accessible and easily cleanable or shall be designed for in-place cleaning. The manufacturer shall provide written instructions

44、 for the cleaning and sanitization of all food zones including those in remote product supply systems. 5.1.4 Food zones for which in-place cleaning is intended shall be designed and manufactured so that cleaning and sanitizing solutions may be circulated or passed throughout the fixed system. The de

45、sign shall ensure that cleaning and sanitizing solutions contact all food contact surfaces. The system shall be self-draining or capable of being completely evacuated. Equipment and appurtenances designed for in-place cleaning shall have a section of the cleaned area accessible for inspection or sha

46、ll provide for other acceptable inspection methods. The manufacturer shall provide written instructions for the cleaning and sanitization of all food zone surfaces for which in-place cleaning is intended. The type and concentration of sanitizing agent recommended in the instructions by the manufactu

47、rer shall comply with 40 CFR 180.9403. 5.1.5 All food contact surfaces shall be exposed to sanitizing solutions during the manufacturers recommended mechanical sanitization procedures. Areas having direct product contact shall be self-draining or otherwise designed to be completely evacuated of prod

48、uct and sanitizing solutions. 5.1.6 Dispensing freezers shall be equipped with a means of collecting and removing product leakage that may occur. 5.1.7 Splash zone surfaces shall be accessible and easily cleanable. 5.1.8 Nonfood zone surfaces shall be accessible and cleanable. 5.1.9 Unexposed nonfoo
