The large electric blast drying oven is a device used to dry items, which uses the electric blast method to provide a drying heat source, and makes the items quickly obtain heat and dry them through circulating blast. It is mainly composed of box, heating source, fan, temperature control system, control panel and other parts. The cabinet is generally made of high-quality steel plate, and the heating element and fan are provided inside.
Hot air is generated from a heating source and circulated into the box by a fan. When the item is placed in the drying oven, the hot air will absorb the moisture on the surface of the item and expel the moisture out of the drying oven through a fan. This process is constantly cycled to achieve rapid drying of items; It is widely used in food, medicine, chemical industry, metallurgy, electronics, automobile, furniture and other fields. For example, it can be used to dry food, medicinal materials, chemical raw materials, electronic components, or to conduct laboratory tests.
Large electric blast ovens usually have a temperature control system that allows the drying temperature to be set as needed. The temperature control system usually adopts digital control, which can monitor and adjust the temperature in the box in real time; Equipped with safety protection devices, such as over-temperature protection, short-circuit protection, etc., to ensure the safe operation of the equipment; When using, you should pay attention to the placement and cleanliness of the items, so as not to affect the drying effect. In addition, it is also necessary to maintain the equipment regularly to keep it running properly.
The workflow of a large electric blast dryer generally includes the following steps:
1.Place the object to be treated on a tray or shelf in the drying oven, close the door and set the temperature and time parameters as needed.
2.Turn on the power supply, start the heating element of the electric heater, and adjust the temperature in the box to the set temperature through the controller.
3.The blower is activated to introduce outside air into the drying oven through a mechanical device. The function of the blower is to accelerate the evaporation of water and improve the drying effect.
4.The air volume generated by the blower is discharged through the exhaust system, which is conducive to removing moisture in the box and maintaining a dry environment.
5.Once the temperature inside the drying oven reaches the set temperature, the controller will automatically adjust the electric heater power to maintain a constant temperature.
6.Through temperature sensors and other equipment, the temperature in the drying oven is constantly monitored to ensure the drying effect and safety.
7.When the set time is reached or the degree of dryness meets the requirements, the drying oven will sound or a notification message will be displayed on the display screen to remind the operator to process the result.
8.Turn off the power, stop the heating and blower work, and after the drying oven cools, you can open the door and take out the processed objects.
It should be noted that the specific electric blast dryer workflow may vary depending on the equipment model and application field, and the above steps are for reference only.
