AJ-80 Vision Series
Specifications
NOTE:
The AJ-80 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 either through hitemp sanitization utilizing 180-195°F fresh water rinse or
through low-temp sanitization utilizing a sanitizer agent
(5.25% sodium hypochlorite) injected into 140°F minimum 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 of 160°F
(140°F in a low-temp chemical sanitizing machine) 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. For hi-temp
sanitizing, the unit must be installed to a potable water
line capable of supplying 234 gallons per hour between
180-195°F at 20 PSI flow pressure for maximum hourly
rack capacity of 248 racks per hour. For low-temp sanitizing, the unit must be installed to a potable water line
capable of supplying 234 gallons per hour between 140150°F at 15-25 PSI flow pressure for maximum hourly
rack capacity of 234 racks per hour. An NSF recognized
chemical feeder system must be supplied and installed by
others and must inject a minimum of 50 PPM 5.25%
sodium hypochlorite (chlorine) into the final rinse line to
meet chemical sanitization requirements.
CAUTION:
Use of sodium hypochlorite (chlorine) may
have an adverse effect on materials including, but not
limited to, silver and silver plate, pewter, and aluminum.
CONSTRUCTION:
All stainless steel components
are 18-8 304 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 t
ank 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.
WASH 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 2 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.
Three-phase motors are induction run with external overload protection. Motor shaft is supported by permanently
lubricated grease packed ball bearings.
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 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 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. Singlephase 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 6.9 feet per
minute for hi-temp machines and 6.5 feet per minute for
low-temp chemical sanitizing machines.
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 capac
ity 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 1
10 volt control circuit
transformer. Again, the Adjust-A-P
eak 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 20 separate stripping nozzles through three
upper arms and two lower arms. 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 five 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
20.0 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
Conveyors
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.
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 (low-temp chemical sanitizing machines
only) into the final rinse line by others. Total final rinse
flow rate is 3.9 GPM.
DRAIN, OVERFLOW, AND MAKE-UP:
The
machine is designed to maintain appropriate prewash and
wash tank water levels at all times even at low pressures.
The overflow system is designed to automatically skim
the surface of both tanks. 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. Large levers located on
the front panel of the machine operate drain valves and
drains the prewash and wash tanks completely.
PRESSURE REDUCING VALVE:
Factory installed on incoming water line to control water
pressure.
Additional Standard
Equipment:
• Vent cowls/splash shields with 4” x 16” openings
covered with removable plates for connection to
exhaust ducts when required.
• Flexible strip curtains provided at the ends of the vent
cowls as well as at the ends of the machine and separating the prewash, wash, and final rinse compartments.
• Extra large inspection doors located on front of the
machine for easy access and cleanability and requiring
only one hand operation.
• Safety door switches shut down the machine should
either door be opened during operation.
• Stainless steel front appearance panel.
• Positive low level water protection for wash
tank heat.

Wash Tank Heating Equipment
(Choose One):
ELECTRIC:
Low watt density 15 KW tubular heating
element mounted inside the wash tank and easily
removable from the outside. The heater is protected by a
stainless steel float system as well as high limit overload
protection. Tank water temperature is controlled and
maintained by a fast reacting thermostat which controls
the heating element.
STEAM:
Stainless steel coils are utilized rather than
injectors so that contaminated steam being injected into
the water is not an issue. Stainless steel tubular steam
coils are mounted inside the wash tank below the optimum water level. The coils are protected by a stainless
steel float system. An external steam “Y” strainer and
high temperature steam solenoid regulates the flow of
steam through the coil. Tank temperature is controlled
and maintained by a fast reacting thermostat which controls the operation of the steam solenoid. A float and
thermostatic steam trap is provided and removes steam
condensate from the steam coils which can either be
plumbed to a drain or pumped back to the boiler if a
condensate return system is available. Steam coils
require a minimum of 10 PSIG flowing steam supply and
a maximum of 20 PSIG. Install with a steam pressure
regulator (by others) if steam supply exceeds 20 PSIG.
