37.110.414    MACHINE CONSTRUCTION: INTERIOR

(1) All interior surfaces and component parts of the vending machine shall be so designed and constructed as to permit easy cleaning, and shall be kept clean. All product contact surfaces of the machine shall be smooth, non-toxic, corrosion resistant, and relatively nonabsorbent material, and shall be capable of withstanding repeated cleaning and bactericidal treatment by normal procedures. Such surfaces shall be protected against contamination.

(2) This rule shall be deemed to have been satisfied when the following requirements are met:

(a) The non-product contact surfaces of the interior vending machines shall be so designed and constructed as to permit easy cleaning, and to facilitate maintenance operations. Inaccessible surfaces or areas shall be minimized.

(b) All product contact surfaces of vending machines shall be smooth, in good repair, and free of breaks, corrosion, open seams, cracks and chipped places. The design of such surfaces shall be such as to preclude routine contact between food and V-type threaded surfaces. All joints and welds in product contact surfaces shall be smooth, and all internal angles and corners of such surfaces shall be rounded to facilitate cleaning.

(c) All product or ingredient contact surfaces of vending machines, including containers, pipes, valves and fittings shall be constructed of non-toxic corrosion resistant and relatively nonabsorbent materials and shall be kept clean. All containers, valves, fittings, chutes and faucets which are in contact with food shall be easily and readily removable and so fabricated as to be easily disassembled and when disassembled, all surfaces shall be visible for inspection and cleaning. In machines of such design that product contact pipes or tubing are not readily removable, in-place cleaning of such pipes and pipe fittings may be permitted, provided they are so arranged that cleaning and bactericidal solutions can be circulated through the fixed system, such solutions will contact all interior surfaces, the system is self-draining or otherwise completely evacuated, and the cleaning procedures result in thorough cleaning of the equipment.

(d) The openings into all non-pressurized containers used for the storage of vendable foods and ingredients, including water, shall be provided with covers which prevent contamination from reaching the interior of the containers. Such covers shall be designed to provide a flange which overlaps the opening, and shall be sloped to provide drainage from the cover surface. Any port opening through the cover shall be flanged upward at least 3/8 inch and shall be provided with a cover which overlaps the flange. Condensation or drip deflecting aprons shall be provided on all piping, thermometers, equipment, rotary shafts, and other functional parts extending into the container unless a water-tight joint is provided. Such aprons shall be considered as satisfactory covers for those openings which are in continuous use. Gaskets, if used, shall be of a material which is non-toxic, relatively stable, and relatively nonabsorbent and shall have a smooth surface. All gasket retaining grooves shall be readily cleanable.

(e) The delivery tube or chute and orifice of all bulk food and bulk beverage vending machines shall be protected from normal manual contact, dust, insects, rodents, and other contamination. The design shall be such as to divert condensation or other moisture from the normal filling position of the container receiving the food or beverage. The vending stage of such machines shall be provided with a tight fitting self-closing door or cover which is kept closed except when the machine is in the process of delivering food or beverage.

(f) The product storage compartment within vending machines dispensing packaged liquid products shall be so constructed as to be self-draining or shall be provided with a drain outlet which permits complete drainage of the compartment. All such drains shall be easily cleanable.

(g) Opening devices which come into contact with the product or the product contact surface of the containers shall be constructed of smooth, non-toxic corrosion resistant and relatively nonabsorbent materials. Unless the opening device is of a single-service type, it shall be readily removable for cleaning and shall be kept clean. Parts of multi-use opening devices which come into contact with the product or product contact surface of containers shall be reasonably protected from manual contact, dust, insects, rodents and other contamination, and such parts shall be readily removable for cleaning and shall be kept clean.
