Third, product features


1. The box body is made of mirror stainless steel argon arc welding, and the outer part of the box is made of high quality steel plate, which is beautiful in appearance and novel in appearance;


2. The microcomputer P.I.D temperature controller with over-temperature protection and digital display is accurate and reliable with timing function temperature control;


3. The hot air circulation system consists of a fan that can continuously rotate at high temperatures and a suitable air duct. Improve the temperature uniformity in the working room.


Fourth, the structure overview


JD-201X series drying oven is electric heating constant temperature blast drying box, the outer shell is made of high quality steel plate, the exterior is made of electrostatic spray; the inner chamber is made of mirror stainless steel plate; the multi-layer carrier bracket is set inside, the height position is adjustable At the same time, a suitable hot air circulation system is installed, and the heat insulation layer is filled with ultra-fine glass wool. The door is provided with a double-layer tempered glass observation window for easy observation; the contact between the working chamber and the door is sealed with a silicone sealing ring to ensure a high degree of sealing between the working chamber and the door, and the electrical control panel is arranged on the left of the box. side.


The heating system inside the box is composed of electric heater, fan, suitable air duct structure and temperature controller; the temperature control precision is high, the set temperature has protection device, and it is equipped with alarm function and timing function.


Fifth, the method of use.


1. Place the dried object in a dry box, turn off the power after closing the door;


2. Turn the power switch to “1”, at this time the power indicator light is on, and the temperature controller has a digital display;


3. Panel indication:


How to use the temperature controller:


Click the set button to enter the temperature setting state, modify the desired value by adding, decreasing and shifting keys; press the setting button to enter the time setting state, by increasing, decreasing and shifting keys Modify the desired value and press the SET button to save and exit the setting. When the time is set to “0”, it means there is no timing function; when the set time is not “0”, the last decimal of the lower row of the display window lights up, and after the measured temperature reaches the set temperature, the timer starts counting. The lit decimal point flashes. When the time is up, the operation ends. The lower display shows “End” and the buzzer sounds for 30 seconds. Press and hold the decrease button for 4 seconds, the program will restart running, and when the buzzer beeps, the increase button can be used to silence the sound.


When the controller's sensor is short-circuited, the upper display of the temperature display window displays “□□□”, the buzzer will beep, and the increase button can be used to silence the sound; when the sensor is short-circuited, the lower display of the temperature display window displays “□□□”. In the above case, please check the wiring and sensor carefully, or replace the sensor directly.

In the normal state, long press the set button for 4 seconds, enter the internal parameter state, enter the password LC=3, click the set button to enter the internal menu, in the internal parameter state, press and hold the button for 4 seconds to exit.


Parameter indicationparameter nameParameter function descriptionRange (factory parameter)
ALOver temperature alarmWhen PV>SP+SL, the temperature alarms and there is a buzzer sounding.0.0~20.0(5.0) ℃
PProportional bandTime proportional adjustment. Decrease P to speed up heating output; increase P to reduce overshoot(0.0~50.0)35.0
PbZero adjustmentCan be used to correct errors caused by sensor measurements.-99.9~60.0(0) ℃
PKFull scale adjustmentWhen the actual temperature is deviated, the parameter value can be corrected. PK=1000* (mercury thermometer reading - current temperature measurement) / current temperature measurement-999~999(0)
rHRangeTemperature measurement, set maximum(0.0~400.0) 400.0

4. According to the degree of moisture of different items, the drying time is selected accordingly;


5. After drying, turn the power switch to “0” and turn off the power.


Six, matters needing attention


1. The oven enclosure must be effectively grounded to ensure safe use;


2. The power should be turned off after use;

4. The drying oven should be placed in a room with good ventilation, and no flammable or explosive materials should be placed around it;


5. Do not over-extrude the contents of the drying box, and leave enough space to facilitate hot air circulation;


6. The inside and outside of the box should always be kept clean and hygienic;


7. When the working temperature is too high, after the machine is turned off, the door should be opened to reduce the temperature inside the box, and then the items should be taken out to prevent burns;


8. Unauthorized removal of the cabinet is not permitted. If the product is damaged, the user is responsible for it.
