Specifications
NOTE: The TSC-66 series conveyor dishmachines are N SF International Inc. (NSF) and Underwriters Laboratories Inc. (UL) listed. They also meet the require- ments of A.S.S.E. Standard No. 1004.
PERFORMANCE: Fully automatic, single tank, rack conveyor dishwasher designed to wash, rinse, and sani- tize tableware and utensils commonly associated with the preparation and consumption of food items in a com- mercial 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 first through a recirculatied (120 GPM) 110 - 140°F prewash and then through a recirculating deter- gent 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 hi-temp sanitizing, the unit must be installed to a potable water line capable of supplying 66 gallons per hour between 180-195°F at 15-25 PSI flow pressure for maximum hourly rack capacity of 119 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”.
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 pre- wash tank through the manifolds and prewash 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 1 H P 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 over- load 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 protec- tion. 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 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 7.0 feet per minute for hi-temp machines.
CHAMBER: The chamber has a standard clearance of 18”.
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. The unit is completely wired with 105°C, 600V thermoplastic insulated wire and routed through UL approved conduit.
FILL: Initial fill of the prewash tank and wash tank is automatic when the machine is initially energized. The prewash tank fill line needs to be hooked up to a 110 - 140°F potable water line; 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 standard solenoid valves and vacuum breaker assemblies. The incoming water solenoids are activated by stainless steel float systems located in the tanks for required maintenance of the water levels.
RECIRCULATING PREWASH: The prewash tank itself has a 17.25 gallon capacity and maintains the water level with a separate fill connection from the rest
of the machine. The automatic fill is controlled through an internal float and an external solenoid valve. Washing action is accomplished by recirculating water in the pre- wash tank through upper and lower prewash arms. All prewash arms are easily removable and along with removable end caps, are easily cleanable without the use of tools.
RECIRCULATING WASH: The wash tank itself has a 20.4 gallon capacity and maintains that level with a skimming type overflow. Washing action is accom- plished 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 con- trolled at approximately 2 GPM. The arms themselves are extended and create a longer wash section than compet- itive models. Wash section is automatically activated by racks as they pass through. Wash arms, upper and lower, contain 36 separate stripping nozzles for superior perfor- mance. All 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 pro- vided to allow easy installation of detergent concentra- tion 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 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 wash tank water levels at all times even at low pressures. The over- flow system is designed to automatically skim the sur- face 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 locat- ed 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.
