FUNCTIONAL DESCRIPTION
The GalleyMaster Dishwasher consists of a wash sec-
tion and a rinse section, each with a solution tank, upper
spray chamber, and front access door. Solutions in
each tank are heated to the operating temperatures
(150° F. wash, 160°rinse) by either submerged steam
coils or electric immersion heaters. Dishware is carried
in 20" by 20" racks, through the wash and rinse sections,
by a double chain conveyor system.
In the tank of each section, a centrifugal pump draws the
hot solution through a suction strainer and then forces
the solution under pressure to the upper and lower spray
manifolds, where the solution exits through slots and
impacts against the dishware in the moving rack. The
spent solutions return to their respective tanks through
the scrap trays, where debris from the dishware is cap-
tured for later disposal.
In the wash tank, the detergent strength is maintained by
a concentration sensing controller and detergent supply
reservoir.
A hot fresh final rinse zone follows the recirculated rinse
zone. The incoming fresh water supply is first reduced
to 20 psig. by a pressure reducing valve and then
heated to 180° F. (minimum) by either a steam powered
heat exchanger or an electrically powered booster
heater, located adjacent to the dishwasher. The hot
rinse water enters the rinse chamber through upper and
lower rinse manifolds, and exits through rinse nozzles
and impacts against the dishware in the moving rack.
The spent rinse water returns to the re-circulated rinse
tank through the scrap screens.
Both the steam and electric powered boosters have a
low water temperature interlock that prevents or inter-
rupts washing when the water in the booster is below
180° F.
The residual heat in the final rinse water helps to main-
tain the recirculated rinse tank temperature. The addi-
tional volume of fresh rinse water, when added to the
rinse tank, increases the solution level and then over-
flows into the drain, carrying away any floating grease
and debris.
PART 1 TECHNICAL INFORMATION
A feed pump injects a conditioner into the final hot rinse
water. This conditioner improves the rinsing and drying
of the dishware by promoting a "sheeting" action of the
rinse water.
A remote electrical control enclosure contains magnetic
contactors, overload protection for the pump and drive
motors, control relays, selector switches, and pilot lights.
A second machine mounted enclosure contains similar
controls for the optional power unloader.
