Blast Drying Oven

The electric blast drying oven is a kind of our drying equipment. The inner box is made of mirror stainless steel argon arc welding, and the outer box is made of high-quality steel plate. The hot air circulation system is composed of fans that can run continuously at high temperature, so that the temperature in the working room is more uniform. For industrial and mining enterprises, laboratories, scientific research units, etc. for drying, baking and melting wax, and sterilization.

What is a electric blast drying oven?

The electric blast drying oven laboratory adopts the electric heating method to carry out the blast circulation drying test, and the ventilation circulation fan blows out hot air to balance the temperature in the electric heating blast drying oven. Under the action of the fan, the electric heating blast drying oven can quickly take away the volatile substance molecules volatilized from the surface of the material through air exchange, to achieve the effect of drying the material quickly.

Parts of electric blast drying oven

The outer shell is welded with a high-quality steel plate, the surface is sprayed, and the inner steel plate is sprayed with high-temperature resistant silver powder paint or stainless steel plate. The temperature insulation adopts ultra-fine glass wool, the box door is equipped with a double-layer glass observation window, and the studio and box door are equipped with heat-resistant silicone rubber or asbestos rope insulation seal. The power switch, temperature control, er and other operating parts of the drying box are concentrated in the front of the box, which is easy to operate. The heating and constant temperature system in the box is composed of an anelectric heater, temperature controller, fan, and suitable air duct structure. When the power is turned on, the fan works at the same time, the heat generated by the electric heater is discharged through the air duct, and the dry items in the workroom are then sucked into the fan so that the temperature can be uniform through continuous circulation. The temperature controller is a microcomputer, an intelligent digital temperature controller. It adopts progressive heating to minimize temperature overshoot. It has aaself-tuning function and high-temperature control accuracy. The set temperature has a protection device and a tracking alarm function.

Electric blast drying oven structure

1. The shell is made of cold-rolled steel plate, and the surface is treated by electrostatic spraying, which is beautiful and elegant;

2. The inner tank is made of stainless steel plate or cold-rolled steel plate after anti-corrosion treatment and processing;

3. There is a glass observation window in the middle of the box door, which can observe the situation of the heated items in the workworkroomany time.

4. The door of the box is inlaid with rubber strips, which have good sealing and prevent heat loss;

5. The temperature of the studio is digitally displayed, which is easy to observe and read;

6. The temperature controller and sensor with time proportional adjustment function are used as the temperature measurement and temperature control system of this equipment, with small measurement error and hhigh-temperaturecontrol accuracy;

7. An exhaust valve is set on the upper side of the studio, and the moisture released by the heated items can be discharged out of the box at any time during the working process.

How to use the electric blast drying oven

1. Place the prepared items to be dried inside of the blast drying box. There must be a certain space around the items. At the same time, the environment of the studio where the items are located must have sufficient airflow. The blast drying box The box door must be tightly closed.

2. The adjustment method of the air door of the blast drying box: first, we must understand the drying degree of the items, and then adjust the air door appropriately. If the item is damp, the damper should be adjusted more.

3. How to start the blast drying oven laboratory: First find the power button of the drying oven. If the indicator light of the power source is on, then the motor of the blast drying oven is running. When the temperature controller completes the self-check, the blasting The PV display of the drying oven should show the measured temperature, and the SV display should show the set temperature so that the blast drying oven starts to work normally.

4. How to set the temperature: find the set button and press it. When the PV display shows 5p, use the up and down arrows to adjust the temperature of the SV display, just adjust it to the desired temperature. After completing the setting, press the set button again, when the PV display shows the word 5t, that is, the PV display enters the timing state, if no timing is required, press the set button again, when the PV display shows the measured value. temperature, the set temperature appears on the SV display to complete the temperature setting.

5. The method of shutting down the electric heating blast drying oven: After finishing the drying of the items, if you want to dry other items, turn off the switch of the fan first, to prevent the drying material from being blown away, and then replace the desiccant, When replacing items, be careful not to touch the edge of the drying box, and finally close the box door of the blast drying box, and then turn on the fan. If you don't want to take out the items immediately, adjust the damper to z, and then turn off the power, so that the inside of the drying box can continue to be dry. If you do not need to dry other items, directly adjust the damper to three places, then turn off the power switch of the blast drying box, and then wait for a while, when the temperature of the box is lowered, take out the items, and finally talk about blast drying Clean the inside of the box.

Advantages of electirc blast drying oven

1. Safe and convenient to use, novel and beautiful in shape, mirror stainless steel studio, high-quality steel plate electrostatically sprayed shell, double-layer tempered glass observation window, stainless steel polished shelf, shelf support can be adjusted arbitrarily;

2. Back heating type, horizontal forced convection, imported fan is selected, and the air volume in and out can be adjusted to ensure uniform temperature in the studio;

3. With sensor fault alarm, over-temperature alarm, self-diagnostic dynamic control, temperature display correction, parameter memory and timing functions up to 9999 minutes;

4. The blast drying box is a studio made of high-quality stainless steel, with rounded corners to make cleaning more convenient;

5. An optional independent temperature-limiting control system, which automatically interrupts work when the temperature is exceeded;

6. The temperature control system of high-performance CPU processing chip and high-sensitivity, high-precision platinum resistance sensor makes the temperature control more convenient and the operation more convenient.
