4.1 Conformance to NSF/ANSI 51
Materials shall conform to the requirements in NSF ANSI 51 applicable to the zone in which the material is used.
4.2 Zone-specific materials requirements
4.2.1 Glass
Glass and similar materials shall not be used where fragments could enter bulk food or fall into the food zone. Glass used in the splash and non-food zones shall be heat tempered safety glass. If protective channels are used, they shall be tight fitting.
4.2.2 Solder
Solder containing lead as an intentional ingredient shall not be used in a food zone or splash zone.
5 Design and construction
This section contains design and construction requirements for equipment covered within 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 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 cleaning 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 cleaning 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 for 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 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 §18O.94O.
5.1.6 Splash zone surfaces shall be accessible and easily cleanable.
51.7 Non-food zone surfaces shall be accessible and cleanable.
5.1.8 Unexposed non-food zone surfaces shall be accessible or closed.
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 minimum continuous radii of 1/8 in (3 mm). Lesser radii may be used when necessary to ensure the proper functioning of equipment components. Greater radii shall be provided. if necessary, to ensure adequate cleaning, maintenance, and product flow.
5.2.2 Solder and other fillet material shall not be used to obtain a required radius in a food zone.
5.3 External angles and corners
Exposed external angles and corners in a food zone shall be sealed and smooth (see figure la).
5.4 Fasteners
5.4.1 Fasteners shall not be used in a food zone. Threaded components (other than fasteners) are permitted in a food zone when necessary for the proper functioning of the vending machine. Threads in a food zone shall be American Standard 60 Stub or equivalent. To facilitate cleaning, exposed threaded components shall have a major diameter of in (16 mm) or greater. There shall be no more than eight exposed threads per 1 in (25 mm) in a food zone.
5.4.2 Fasteners in a splash zone or non-food zone shall not have deep recesses in the head. Examples of fasteners meeting this requirement include slot-head and Phillips-head screws and flush-break pop rivets. Non-flush-break pop rivets shall be capped or filled with a food-grade material.
5.4.3 Allen screws shall not be used in a splash zone. Allen screws may be used in a non-food zone provided that the heads are capped or filled with a food grade material.
5.4.4 Fasteners shall be tight fitting to the surface.NSF ANSI 25 pdf download.
