42、thin the scope of this Standard. 5.1 General sanitation 5.1.1 Vending machines shall be designed and manufactured to prevent the harborage of vermin and the accumulation of dirt and debris, and to permit the inspection, maintenance, servicing, and cleaning of the equipment and its components. 5.1.2

43、Vending machines and components shall be designed so that food and ingredients may be added and unit servings of bulk or packaged foods may be dispensed or removed in a sanitary manner. 5.1.3 Vending machines with food contact surfaces shall have a clip or other device suitable for holding a cleanin

44、g record inside the machine cabinet. 5.1.4 Food zones shall be readily accessible and easily cleanable, or shall be designed for in-place cleaning when a readily accessible design is not feasible. 5.1.5 Food zones for which in-place cleaning is intended shall be designed and manufactured so that cle

45、aning and sanitizing solutions may be circulated or passed throughout the fixed system. The design 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 or appurtenances designed fo

46、r in-place cleaning shall have a section of the cleaned area accessible for inspection or shall provide for other acceptable inspection methods. Instructions for conducting in-place cleaning shall be posted inside the vending machine cabinet and in the written manual. The manufacturer shall provide

47、written instructions for cleaning and sanitizing 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 manufacturer shall comply with 40 CFR 180.9403. 5.1.6 Splash zone surfaces shall be accessible and

48、 easily cleanable. 5.1.7 Non-food zone surfaces shall be accessible and cleanable. 5.1.8 Unexposed non-food zone surfaces shall be accessible or closed. 2017 NSF NSF/ANSI 25 2017 4 5.2 Internal angles and corners 5.2.1 Internal angles or corners of 135 or less in a food zone shall be smooth and have

49、 minimum continuous radii of 1/8 in (3 mm). Lesser radii may be used when necessary to ensure the proper functioning of equipment components.
