Operating precautions for blast drying oven

Blast drying oven introduction

Electric thermostatic blower drying oven, Zui high temperature 200 ° C, 250 ° C 300 ° C three specifications, mainly used for baking, drying, heat treatment and thermal processing, agricultural production, scientific research, medical and health units, experimental real Use, but not applicable to volatile items, so as not to cause explosion, the temperature control system uses TEF series pointer type temperature controller, which has the advantages of convenient adjustment and reliable temperature control performance.

Blast drying box instruction manual

1. Before powering on, check the electrical performance of the drying box first, and pay attention to whether there is any open circuit or leakage.

2. Wait until everything is ready to stop, put the test sample, close the door, and open the exhaust valve.

3. After connecting the power supply, turn on the power heating switch, activate the temperature rise button, and control the temperature according to the instructions of the “TDA” series pointer type temperature controller. At this time, the heating indicator light starts to light up in the box. Note: When the temperature rise starts, the temperature rise button must be activated. When the two groups of heating series work, when the temperature rises to the set temperature, the heater will be automatically disconnected, and the heater will be left. When the temperature rises to the set temperature, the heater will be automatically disconnected. All the way to work with the heater, if you need to heat up, you must start the heating button again.

4. In the * constant temperature state, the temperature will continue to rise, which is the effect of residual heat. This phenomenon is stable in about 30 minutes.

Air drying oven

1. The inside of the box must be effectively grounded. Do not touch the electrical circuit with your hands. Do not use wet items to clean and clean the instrument with water.

2. When the instrument is in working condition, do not splash water on the glass observation window to break the crack.

3, flammable materials are not easy to put into the box, when doing high-temperature baking, the burning temperature value of each item is measured in advance, especially the gas items, should prevent explosion caused by over-temperature, Note: This type of drying box is not explosion-proof products.

4. The line should be kept dry and clean. If a fault occurs, the power should be cut off and repaired.

5, the blast motor can not work continuously, zui does not exceed 4 hours
