Principles of Food Sanitation

this approach include increased labor require-
ments and water condensation on equipment,
walls, and ceilings. It is difficult to remove
heavy soil with this system.

High-Pressure, Low-Volume Cleaning

High-pressure, low-volume spray cleaning
is a viable method in the meat and poultry
industry because of the effectiveness with
which it removes tenacious soils. With this
equipment, the operator can more effectively
clean difficult-to-reach areas with less labor,
and the cleaning compound is more effective
at a lower temperature.
This hydraulic cleaning technique may
involve portable units. This portable equip-
ment can be utilized for cleaning parts of
equipment and building surfaces and is espe-
cially effective for conveyors and processing
equipment when soaking operations are
impractical and hand bushing is difficult and
labor-intensive.
The metering device and controls of a cen-
tralized high-pressure cleaning unit are illus-
trated in Chapter 11. A dispensing nozzle for
this equipment is pictured in Figure 17–3.

Foam Cleaning

Foam is particularly beneficial in cleaning

large surface areas of meat and poultry plants

and is frequently used to clean transportation

equipment exteriors, ceilings, walls, piping,

belts, and storage containers. Portable foam

equipment is pictured in Figure 17-4. In size

and cost it is similar to portable high-pressure

units. Centralized foam cleaning applies clean-

ing compounds by the same desirable features

as a centralized system.

Gel Cleaning

This equipment is similar to high-pressure

units, except that the cleaning compound is

applied as a gel rather then as a high-

pressure spray. Gel is especially effective for

cleaning packaging equipment because it

clings to the surfaces for subsequent soil

removal. Equipment cost is similar to that of

portable high-pressure units.
