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
15.4gallon 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.
