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.
Nonproduct contact surfaces of the interior
of vending machines shall be so designed and constructed as to permit
easy cleaning and to facilitate maintenance operations and shall be
kept clean. Inaccessible surfaces or areas shall be minimized.
All product contact surfaces of vending machines
shall be smooth, in good repair and free of breaks, corrosion, open
seams, cracks and chipped places and shall be kept clean. The design
of such surfaces shall be such as to prevent 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.
All product or ingredient contact surfaces of
vending machines, including containers, pipes, valves and fittings,
shall be constructed of nontoxic, 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 is not readily removable, in-place cleaning
of such pipes and pipe fittings is permissible, provided that they
are so arranged that cleaning and bactericidal solutions can be circulated
throughout 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.
The openings of all nonpressurized 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 openings 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 watertight 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 nontoxic, relatively
stable and relatively nonabsorbent and shall have a smooth surface.
All gaskets retaining grooves shall be readily cleanable.
The delivery tube or chute and orifice of all
bulk foods 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-enclosing door or cover which is kept closed,
except when the machine is in the process of delivering food or beverage.
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 draining of the compartment. All such drains shall
be easily cleanable.
Opening devices which come into contact with
the product or the product contact surface of the containers shall
be constructed of smooth, nontoxic, 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 multiuse opening devices which come into contact with
the product or product contact surface of containers shall be protected
from manual contact, dust, insects, rodents and other contamination,
and such parts shall be readily removable for cleaning and shall be
kept clean.
