Precautions for the Operation and Maintenance of Blast Drying Ovens

Wiki Article

Blast drying ovens are characterized by excellent design, novel appearance, sophisticated craftsmanship, accurate temperature control, stable performance, easy maintenance and convenient operation. They are widely used in industrial and mining enterprises, medical and health institutions, pharmaceuticals, biology, agriculture, electronics, chemical engineering, environmental protection, scientific research institutes and other sectors for baking, drying, dissolving and sterilizing items.

Then, what key points should be paid attention to when using a blast drying oven? The following are the key considerations for the use of blast drying ovens:

After connecting the power supply, you can turn on the two groups of heating switches, and then set the required temperature through the buttons on the control instrument. When the indicator light is on, you can turn on the blower switch at the same time to start the blower.

When the temperature rises to the required level, the indicator light will go off. At the initial stage of constant temperature, the temperature may continue to rise due to residual heat, and this phenomenon will stabilize in about half an hour. During the constant temperature period, the temperature is automatically controlled by the thermostat inside the oven, requiring no manual supervision.

During constant temperature operation, one group of heating switches can be turned off, leaving only one group of electric heaters working to avoid excessive power affecting the sensitivity of temperature control.

The blast drying oven should be placed on a level surface indoors.

A knife switch with iron casing should be installed in the power supply line for the exclusive use of the blast drying oven, and the oven shell should be grounded.

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

When all preparations are completed, the samples can be placed inside. Close the oven door and unscrew the exhaust valve on the top, then connect the power supply to start operation.

Do not remove the side door arbitrarily to avoid disturbing or altering the circuit. The side door can only be removed for circuit inspection when the blast drying oven malfunctions.

The blast drying oven is non-explosion-proof. Therefore, flammable and volatile substances must never be placed inside, to prevent explosion hazards.
