a、Main structure

Aeration room size(L*W*H): 8000*3000*2300=55.2m³, one room.

1、 The main structure is built by the demander( thickness no less than 75mm, density not less than 80K, high strength, class A fireproof silica rock plate, double colorful plate with 0.5mm, seamless connection fixed, with ladder for daily maintenance);

2、 Door (self-provided by the customer) shall be made of the same board, the door frame is fitted with a bumper, four frame inlaid sealing tape, maximum seal, door head is fitted with wind curtain, door width 1.35m, double doors , two for each of the loading and unloading doors.

3、 Install 4 moisture-proof and explosion-proof lights on the top, automatic switch.

4、 There are working indicator lights in each preheating room, indicating starting and stopping;

5、 The air duct shall be prepared by demander themselves( It is recommended to use 0.6mm thick stainless steel or galvanized iron sheet, Exterior insulation class B1, 20mm rubber and plastic plate.

b、Heating system

1、 Industrial steam heating;

2、 Adopt heating and humidifying integrated air cabinet, copper tube aluminum fin heat exchanger, The air volume is 2000m cubed /h, the air pressure is 470pa, and the fan is 0.5kw. The preheating room is equipped with one set, the circulating amount in the room is no less than 30 times /h to improve the thermal efficiency.

3、 Each set of wind cabinets is mounted on the preheated roof and hoisted by steel frame, 10 air supply outlets and 4 air return outlets, 10 air regulating valves, 14 guide windows, heat preservation seal treatment, can adjust the wind volume and wind direction;

1、 Preheating room maintains a slight positive pressure after starting the machine, combined with the circulation of wind action to heat exchange, heat conduction, thermal penetration also ACTS on preheated items.

4、 c、Wind changing system

1、 The fan is installed on the roof, and the intermittent exhaust mode is conducive to temperature rise, energy saving and analysis, 2 air vents, equipped with filter, connect the exhaust fan to the main duct, main duct exhaust air or waste gas treatment equipment, exhaust is opened when loading or unloading, wind volume measurement system is set up to detect the effect of air exchange.

2、 After starting the machine, keep the micro-negative pressure in the room, the explosion-proof fan exhausts the air, and the new wind enters in heating product, so as to promote the release of ethylene oxide as soon as possible, which will be discharged by the fan on time;

3、 The fresh air adopts the natural air supply mode, and the tuyere is equipped with filter net.

d、Control system

1、 The aeration room is equipped with two temperature probes, to provide reliable data for the control system, make the aeration room temperature and humidity control accurate, display and monitor the room temperature and humidity. The exhaust system is equipped with sensors to measure the air volume and monitor the exhaust effect in real time, a sensor is installed in the middle of the room to monitor the EO concentration in real time.

2、 The control system adopts IPC and PLC control method, the whole process is fully automatic and can be recorded and printed as required: date, time( minutes ~ hours), lot number, product number, operator, temperature and humidity data, trend chart, historical graph. And all these data can be saved for 5 years (software refer to sterilizer);

3、 Intelligent and humanized operation interface to prevent mis-operation function, batch remind function, parameter alarm function;

4、 Specialized electric control operation desk, Liquid crystal display preheat setting parameters and real-time parameters, indicating switch, emergency stop button, fault alarm;

5、 The recorded data cannot be modified. When the software is updated, all the data can be exported, saved and sent back to the system to get the data;

6、 When the software parameters are modified, they are automatically recorded in the software operating system.
