AJ-64 Vision Series
Specifications
NOTE:
The AJ-64 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 require-
ments of A.S.S.E. Standard No. 1004.
PERFORMANCE:
Fully automatic, multiple 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 accom-
plished 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 150°F
wash water is pumped over the dishrack to remove the
food soil. It then enters the power rinse section where an
initial rinse of 160°F water at 270 (GPM) is pumped over
the dishrack. The rack is conveyor driven into a final
rinse section where a fresh water final rinse spray sys-
tem removes remaining residual detergent and sanitizes.
The unit must be installed to a potable water line capa-
ble of supplying 222 gallons per hour between 180-195°F
at 15-25 PSI flow pressure for maximum hourly rack
capacity of 287 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 and rinse
tank chambers are formed and heliarc welded 16 gauge
#2B finish. Hood is 16 gauge #3 finish. Stainless steel
feet are adjustable ±1/2”.
WASH PUMP:
Internal wash pump located inside
the wash tub is totally stainless steel including the
impeller. The pump itself is totally integral with the motor
and self draining. Wash water is recirculated from the
wash tank through the manifolds and wash arm system
at the rate of 270 GPM.
WASH 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 protec-
tion. Motor shaft is supported by permanently lubricated
grease packed ball bearings.
POWER RINSE PUMP:
Internal power rinse
pump located inside the power rinse tub is totally stain-
less steel including the impeller. The pump itself is totally
integral with the motor and self draining. Rinse water is
recirculated from the tank through the manifolds and
rinse arm system at the rate of 270 GPM.
POWER RINSE PUMP MOTOR:
A 2 HP total-
ly 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 over-
load 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
not to interfere with spray patterns in the wash, power
rinse, and final rinse sections. 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 protec-
tion. Pawl bar conveyor drive unit is mounted on the left
hand side of the machine and is enclosed with a remov-
able stainless steel cover. Maximum conveyor speed is 8.0
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 con-
veyor 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 uti-
lizing 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, power rinse, and final rinse sections only
when a rack is being washed or rinsed. It will turn the
conveyor off when a rack exits the machine and there
are no other racks in the unit. 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, power rinse, and final rinse contact time. The unit
is completely wired with 105°C, 600V thermoplastic insu-
lated 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 con-
trol box.
FILL:
Initial fill of wash and power rinse tanks is auto-
matic when machine is initially energized. The fill line
needs to be hooked up to a 180°F minimum potable
water line which normally would be supplied by an exter-
nal booster heater or our optional Hatco booster heater
packages. Fill is controlled by a standard solenoid valve
and vacuum breaker assembly. The incoming water sole-
noids are activated by stainless steel float systems locat-
ed in the wash tank and power rinse tank for maintaining
required fill levels.
RECIRCULATING WASH:
The wash tank has a
15.4 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 power rinse section and is controlled at
approximately 2 GPM. The wash arms are 18” long.
Wash performance commences 5” into the machine.
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 remov-
able 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 dis-
penser tubing by others.
POWER RINSE:
The power rinse tank has a 15.4
gallon capacity and maintains that level with a skimming
type overflow. Rinsing action is accomplished by recircu-
lating final rinse water in the tank through upper and
lower wash arms. Makeup water comes from the final
rinse section and is controlled at approximately 2 GPM.
The power rinse arms are 12” long. The power rinse sec-
tion is automatically activated by racks as they pass
through. Power rinse arms, upper and lower, contain 32
separate stripping nozzles for superior performance. Both
power rinse 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.
