Use The maximum working temperature of the blast drying oven is 300°C. It is suitable for baking, drying oven heat treatment or other heating. It is also a laboratory standing instrument.
The working temperature of the drying oven can be increased from room temperature to 30 °C up to the maximum temperature. Within this range, the working temperature can be arbitrarily selected. After the selection, the temperature can be kept constant by the automatic control system inside the box.
The structure of the drying box is precise, the temperature control is sensitive and accurate, and the operation is simple and convenient. The research institutes of the mining industry and colleges and universities can all be adopted.

Use and attention
1. After the power is connected, two groups of heating switches can be turned on, and then the temperature controller rotates from “0†clockwise to “100†index. At this time, the temperature in the box starts to rise, and the indicator light is on. At the same time, it can be turned on. Blower switch to make the blower work.
2. When the temperature rises to the required working temperature (observed from the thermometer in the exhaust valve hole), turn the thermostat knob counterclockwise and turn it until the indicator is extinguished. Make another fine adjustment clockwise until the indicator light is on. So repeatedly adjust to the indicator light alternately open and close at the constant temperature point. At the beginning of the constant temperature, it is likely that the temperature will continue to rise. This is the effect of residual heat. This phenomenon will be stable for about half an hour. During the constant temperature process, the temperature control device will automatically control the temperature, and no manual management is required.
3. After making the above preparations, switch the switch of the digital instrument panel to “Preset†to set the required working temperature (observe the meter display). Select and switch to "measure temperature" to work.
4. When the temperature is constant, a group of heating switches can be turned off and a set of DC electric heaters can work. To avoid excessive power, affect the temperature sensitivity.
5, want to observe the situation of the studio sample, you can open the outer door, watch the glass door inside. However, it is advisable to open the door so as not to affect the constant temperature and cause the glass to suddenly cool and burst.
6, the box should be placed at the indoor level.
7. One switch of iron shell knife should be installed in the power supply line for this box, and the shell should be grounded.
8, before power, first check the electrical performance of the box, and should pay attention to whether there is an open circuit or leakage phenomenon.
9, when everything is ready, you can put the sample, close the door, insert a thermometer in the top of the tank exhaust valve, while opening the exhaust valve, the gap is about 10m/m, then you can connect the power ,start working.
10, can not be arbitrarily removed the side door, disturb or change the line, only when the box fails, the side door can be removed, one by one line inspection. If there is a major fault, you can contact the factory.
11, this box is not explosion-proof drying oven, so with flammable volatile materials, do not put in the oven, so as to avoid explosion.
12. Each drying box is accompanied by two sample shelf plates. The average load of the shelf is 15 kg. Do not place the sample too dense and overloaded so as not to affect the convection of hot air. At the same time, the test piece should not be placed on the bottom heat sink of the studio to prevent overheating and damage the test sample.
