Specifications
NOTE:
The AJ-76 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 with a recirculating prewash 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
prewash section where 120 gallons per minute (GPM) of
110-140°F water is pumped over the rack to mechanically
prepare the tableware for washing. Next, the rack is conveyor driven into a detergent laden wash section where 270
(GPM) of 160°F. Wash water is pumped over the dishrack
to remove the food soil. Finally, the rack is conveyor driven
into a final rinse section where a fresh water final rinse
spray system removes residual detergent and sanitizes. The
unit must be installed to a potable water line capable of
supplying 279 gallons per hour between 180-195°F at 1525 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 prewash tank, 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”.
PREWASH PUMP:
Internal prewash pump located
inside the prewash tub is totally stainless steel as is the
impeller. The prewash pump itself is totally integral with
the motor. Prewash water is recirculated from the prewash
tank through the manifolds and wash arm system at the
rate of 120 GPM.
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.
PREWASH PUMP MOTOR:
A 1 HP totally
enclosed, fan cooled type motor drives the prewash pump
and arms. Single-phase motors are capacitor start, induction run with internal thermal overload protection. Threephase motors are induction run with external overload protection. Motor shaft is supported by permanently lubricated
grease packed ball bearings.
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, counter-weighted,
wide surface pawls. The pawl bar is designed to not interfere with spray patterns in the prewash, 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 prewash, wash, and rinse sections only when a rack is
in place 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 prewash, 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 the prewash tank and the wash tank is
automatic when machine is initially energized. There are
separate fills to each tank and each is controlled by its own
standard solenoid valve and vacuum breaker assembly. The
prewash tank needs to be hooked up to a water line capable of filling with 110-140°F incoming potable water rather
than filling with 180°F from the booster heater through the
wash tank as does the competition. If the cold water thermostat option is utilized in the prewash, an additional cold
water line needs to be hooked up to the machine. The
wash tank fill line needs to be hooked up to a 180°F minimum incoming potable water line which normally would be
supplied by an external booster heater or our own optional
Hatco booster heater packages. The fill solenoids for both
tanks are activated by stainless steel float systems located
in the individual tanks for required maintenance of tank
water levels.
RECIRCULATING PREWASH:
The prewash tank
itself has a 16.0 gallon capacity and maintains that level
with a skimming type overflow. Prewashing action is
accomplished by recirculating 110-140°F water through 12
separate stripping nozzles through two upper arms and one
lower arm. This superior action removes heavy soil and
deposits it in a large outside deep well scrap basket located on the front of the machine for easy access. A secondary removable pump intake strainer protects the pump
itself. Make-up water comes from the wash at the rate of
approximately 2 GPM. All three wash arms are easily
removable and along with removable prewash arm end
caps, are easily cleanable without the use of tools.
RECIRCULATING WASH:
The wash tank has a
20.4 gallon capacity and maintains that level with a skimming type overflow that flows excess wash water into the
prewash tank. Washing action is accomplished by recirculating detergent laden wash 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 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.
