Specifications
NOTE:
The AJ-54 series conveyor dishmachines are
listed by the National Sanitation Foundation (NSF),
Underwriters Laboratories Inc. (UL), and by the Canadian
Standards Association (CSA). They also meet the requirements of A.S.S.E. Standard No. 1004.
PERFORMANCE:
Fully automatic, single tank, rack
conveyor dishwasher designed to wash, rinse, and sanitize tableware and utensils commonly associated with
the preparation and consumption of food items in a commercial foodservice operation. Sanitization is accomplished through hi-temp sanitization utilizing 180-195°F
fresh water rinse. The unit conveys standard 20” x 20”
dishracks through a recirculating detergent laden wash
section where 270 gallons per minute (GPM) of 160°F
wash water is pumped over the dishrack to remove the
food soil. The rack is then conveyor driven into a final
rinse section where a fresh water final rinse spray system removes residual detergent and sanitizes. For hitemp sanitizing, the unit must be installed to a potable
water line capable of supplying 279 gallons per hour
between 180-195°F at 15-25 PSI flow pressure for maximum hourly rack capacity of 270 racks per hour.
CONSTRUCTION:
All stainless steel components
are 304 series stainless steel. No 400 series stainless
steel and/or plastics are utilized. Frame is constructed of
2” diameter stainless steel tubing formed and completely
saddle welded for superior strength. The wash tank, and
rinse chamber are formed and heliarc welded 16 gauge
#2B finish. Hood is 16 gauge #3 finish. Stainless steel
feet are adjustable ±1/2”.
WAS H PUMP:
Internal wash pump located inside the
wash tub is totally stainless steel as is the impeller. The
wash pump itself is totally integral with the motor. Wash
water is recirculated from the wash tank through the
manifolds and wash arm system at the rate of 270 GPM.
WAS H PUMP MOTOR:
A 2 HP totally enclosed,
fan cooled type motor drives the wash pump and arms.
Single-phase motors are capacitor start, induction run
with internal thermal overload protection. Three-phase
motors are induction run with external overload protection. Motor shaft is supported by permanently lubricated
grease packed ball bearings.
CONVEYOR SYSTEM:
Racks are conveyed
through the machine by a center-mounted, heavy-duty
stainless steel pawl bar with stainless steel cast, counterweighted, wide surface pawls. The pawl bar is designed
to not interfere with spray patterns in the wash, and
rinse section. The pawl bar is driven by a 1/4 HP motor
and worm drive gear reduction unit. The conveyor motor
itself is totally enclosed, non-ventilated. Single-phase
motors are capacitor start, induction run with internal
thermal overload protection. Three-phase motors are
induction run with external overload protection. Pawl bar
conveyor drive unit is mounted on the left hand side of
the machine and is enclosed with a removable stainless
steel cover. Maximum conveyor speed is 7.5 feet per
minute.
ADJUST-A-PEAK:
The Adjust-A-Peak feature is a
mechanical feature located on the pawl bar drive unit itself
and allows the end-user to slow down the speed of the
conveyor drive unit when enhanced results are required
(i.e. baked-on food soil) or increase the speed of the conveyor drive unit when maximum capacity is required. By
slowing down the conveyor, a rack of tableware remains in
the prewash, wash, and rinse sections for longer periods of
time. When soil loads are heavy (i.e. pots and pans, trays,
and bun pans), adjusting the conveyor to slower speeds
means outstanding results.
CHAMBER:
The chamber has a standard clearance
of 25” which is the highest clearance in the industry--even higher than competitive higher hood options. This
adds to the versatility of the machine since you can easily
accommodate larger utensils such as sheet pans and 60
quart mixing bowls. The combination of a higher hood in
conjunction with manually slowing down the conveyor utilizing the Adjust-A-Peak feature produces superior results
as well as adding to the versatility of the machine.
CONTROLS:
Controls are located in a stainless steel
control box mounted on top of the machine for ease of
access and increased reliability. Power “ON/OFF” switch
is the only manual switch required. “Energy Guard” fully
automates the machine and utilizes switching logic to
operate wash and rinse sections only when a rack is
being washed or rinsed as well as turning the conveyor
off when a rack exits the machine and there are no other
racks in the machine. Regardless of machine voltage, all
control circuitry will be operated from a 110 volt control
circuit transformer. Again, the Adjust-A-Peak feature
eliminates the need for manual controls since you have
the ability to slow down the conveyor for extended wash
and rinse contact time. The unit is completely wired with
105°C, 600V thermoplastic insulated wire and routed
through UL approved conduit. The control circuit itself is
protected by a manual reset 1 AMP overload protector
located on the front of the control box.
FILL:
Initial fill of wash tank is automatic when
machine is initially energized. The wash tank fill line
needs to be hooked up to a 180°F minimum potable
water line which normally would be supplied by an external booster heater or our optional Hatco booster heater
packages. Fill is controlled by a standard solenoid valve
and vacuum breaker assembly. The incoming water solenoid is activated by a stainless steel float system located
in the wash tank for required maintenance of the wash
tank water level.
RECIRCULATING WASH:
The wash tank itself
has a 20.4 gallon capacity and maintains that level with
a skimming type overflow. Washing action is accomplished by recirculating detergent laden water in the
wash tank through upper and lower wash arms. Make-up
water comes from the final rinse section and is controlled at approximately 2 GPM. The arms themselves are
extended and create a longer wash section than competitive models. Wash performance commences 5” into the
machine unlike other 54” single tank conveyors. Wash
section is automatically activated by racks as they pass
through. Wash arms, upper and lower, contain 43 separate stripping nozzles for superior performance. Both
wash arms are easily removable and along with removable wash arm end caps, are easily cleanable without the
use of tools. Large stainless steel strainer pans, as well
as a pump intake strainer for secondary protection are
readily accessible and removable for cleaning purposes.
Knockouts and connections are provided to allow easy
installation of detergent concentration sensor and dispenser tubing by others.
FINAL RINSE:
Fresh pressurized rinse water enters
the machine through a standard “Y” strainer, solenoid
valve, and approved vacuum breaker assembly and is
plumbed to upper and lower final rinse arms located at
the output end of the machine. Single rows of fan jet
nozzles are located on both rinse arms. Connection points
are provided for both rinse agent injection and sodium
hypochlorite into the final rinse line by others. Total final
rinse flow rate is 4.7 GPM.
DRAIN, OVERFLOW, AND MAKE-UP:
The
machine is designed to maintain appropriate wash tank
water levels at all times even at low pressures. The overflow system is designed to automatically skim the surface of the wash tank. Make-up water from the final
rinse system not only replenishes the wash water but
also helps maintain appropriate water levels as well as
appropriate wash tank temperatures. A large lever located on the front panel of the machine operates a drain
valve and drains the machine completely.
PRESSURE REDUCING VALVE:
Factory installed on incoming water line to control water
pressure.
