DRY HEAT STERILIZER
SPECIFICATIONS:
MATERIAL OF CONSTRUCTION:
- All the internal and external part of sterilizer will be manufactured from stainless steel sheets of 304 quality.
- The sterilizer will be suitably reinforced with angles & section and is insulated with minimum 125mm glass wool & asbestos sheet insulation. The inside of the sterilizer is tapered to get uniform circulation.
- The sterilizer will have two doors one on the sterile side and other on the non-sterile side. Door will be provided with locking arrangement at four point centrally turning screw with type device. Door lips will be covered with silicon gasket to prevent any leakages.
- All the components used inside the sterilizer will be of SS304 including nut, bolts, sensors etc.
- All the joints are welded fully and edges curved.
FINISHING :
External of the sterilizer will be buffed to 150 grit matt finish and Internal will be buffed to 220 grit mirror finish.
INTERLOCKING OF DOORS :
The doors are provided with limit switches and indicating lamps. If the doors is open from one side, the indicating lamps and buzzer will operate on the other side and vice versa. The doors are also provided with interlocking devices by means of solenoids valve. If the door on one side is opened, the door on the other sides gets locked automatically and vice versa
AIR CIRCULATION :
Air inside the sterilizer will be circulated by dynamically balanced stainless steel blower and driven by suitable motor with ISI mark. The special design of the blower ensures equal distribution of air throughout the sterilizer. The blower will suck the air from one side and force it on the other side so that the air current will pass over the boxes loaded on the trolley.
HEATING :
Air inside the sterilizer will be heated by tubular stainless steel air heater of 1KW each (Total -30KW). The heater assembly will be made out of SS316 and will be fitted at the top of the dryer. The heater terminal will be brought out of the sterilizer to eliminate the problem of the terminals burning and black articles due to oxidation of heater terminals due to over heating. The maximum temperature attained inside the sterilizer will be 300’C and is controlled by control panel.
COOLING :
The air inside the sterilizer will be cooled by hepa-filter module, As soon as the sterilization cycle is over, the cooling cycles starts automatically. During cooling cycle the heaters are off and the sterilizer temperature come down to room temperature.
PRESSURE MODULE :
The sterilizer is provided with a pressure module with HEPA FILTER. The module can be fitted at the top or on one side of the sterilizer. The module is connected to the sterilizer by means of S.S. pipe. The Hepa module operate initially during the heating phase & also during the cooling cycle automatically to maintain the positive pressure inside the sterilizer. Manometer probe is provided on the sterilizer to measure the pressure difference. The pressure module is working fully automatic as per our programmed.
This module also opens and closes along with the exhaust damper to maintain positive pressure inside the sterilizer. As the exhaust damper is Solenoid valve operated & is operate by air line connection.
EXHAUST :
The sterilizer is provided with a solenoid air actuator exhaust damper fitted with heat resistant Silicon gasket. This damper opens automatically during initial heating phase to drive out he moisture. As soon as the sterilization temperature is reached the damper closes automatically till the heating cycle is over and then again opens during the cooling cycle.
SENSORS :
There will be eight sensors at the different points inside the sterilizer. The sensors will be of PT-100, 2/3 wire system. The make of the sensor will be of stainless steel. The sensor will be highly sensitive to measure the temperature accurately at eight different points inside the sterilizer.
TROLLEY :
The sterilizer is provided with stainless steel trolley trick fitted with stainless steel and teflon bushes. The trolley is manufactured from stainless steel pipes and is provided with grill type S.S. shelves made out of S.S. bars of 10mm. spec. customers requirement dimensions will be as per the technical sheet attached.
CARRIAGES :
Two nos. carriages for the above trolley truck are supplied along with sterilizer. Both the carriage are made out of SS304 and with SS304 rails. The carriage keep the trolley off the floor to avoid dirt contamination on the trolley.
COOLING COIL (OPTIONAL) :
Cooling coils are made out of SS304 are also provided inside the sterilizer. Inlet and Outlet connection are also provided inside the sterilizer. Water can be circulated insides the coils for faster cooling inside the sterilizer.
CYCLE TIME :
Loading / Unloading 0 HR. 30 Min.
Heating Time 1 HR. 00 Min.
Hold Time 1 HR. 00 Min.
Cooling Time 2 HR. 00 Min.
Total 4 HR. 30 Min.
