and can be uniformly administered through
the use of timer switches. Metering of sanitiz-
ing compounds provides a more accurate and
precise application of the sanitizer. The high-
pressure rinse water passes through flow con-
trol with the orifice size necessary to achieve a
pre-specified flow rate. To sanitize, the high-
pressure water passes through the sanitizer
injector, which meters a specific amount of
sanitizer into the water stream. A flood sani-
tizing nozzle may be incorporated to spread
the solution effectively without automation.
An on-board tire sanitizer is available to
reduce contamination of tire treads and
wheels of delivery and service vehicles and
other related equipment that may need sani-
tizing before facility entry. This equipment
combines spray nozzles positioned above
vehicle wheels with a storage tank and pump
to apply disinfectants to tires while the vehi-
cle is in motion.
Sanitation Application Methods
The application methods that are available
provide acceptable methods for transport of
the sanitizer to the desired area. The optimal
method depends upon individual operations.
Chemical sanitizers are normally applied
by one of the following methods.
●Spray Sanitizing. This method involves
use of a sanitizer dissolved in water and
a spray device to transport the sanitizer
to the area to be sanitized.
●Fogging. Fogging involves application of
the sanitizer as a fine mist to sanitize the
air and surfaces in a room.
●Flood Sanitizing. This method involves
the application of a sanitizer dissolved in
water and applied in a large quantity to
ensure extensive exposure. The use of
flood sanitizing has been increased to
combat the proliferation ofL. monocyto-
genes. The disadvantages of this method
are the cost of the sanitizer and water,
and the wet condition created.●Immersion/COP Sanitizing. This tech-
nique involves the submersion of equip-
ment, utensils, and parts in a tank that
contains a sanitizing solution.
●CIP Sanitizing. CIP sanitizing involves
sanitizing by circulation of the sanitizer
inside pipes, lines, and equipment.
●Sanitizing Belt Treatment. Acid liquid
belt treatment for meat and poultry,
fruits and vegetables, and cheese pro-
cessing conveyors can be incorporated
to apply a sanitizer such as a peroxyacid
solution for continuous or intermittent
belt treatment during production.
●Doorway Sanitation Options.For regu-
lar or intermittent high traffic areas
and doorways, infrared sensors detect
motion and automatically dispense a
sanitizing spray or foam to worker boots
and the wheels of plant vehicles and
equipment. For low traffic door and
hallways where foam is not desired, a
sanitizer spray can be set for 10 seconds
of sanitizing every 10 to 15 minutes.Lubrication equipment..........................................................................
Figure 11–13 illustrates typical equip-
ment for effective maintenance of high-speed
bottling and canning conveyors used in the
beverage industry and on shackle chains and
conveyors, smokehouse chain drives, and
other applications requiring precise continu-
ous conveyor and/or chain lubrication. This
principle involves water under pressure during
a reciprocating piston in the chemical pump.
This piston subsequently drives a chemical-
concentrate-metering piston that draws the
lubricant from the drum and injects it into the
water from the cylinder.Summary
A major function of cleaning equipment is
to dispense the cleaning compound and san-
itizer to facilitate cleaning and sanitizing andSanitation Equipment 211
