The working principle, characteristics and application scope of heating tube

No matter in daily life or in industrial electric heating equipment, heating tubes are ubiquitous, but often many customers don't know its working principle. Let me talk about the working principle, characteristics, and application scope of heating tubes.

  Working principle of heating tube:

High-temperature heating wires are evenly distributed in the high-temperature-resistant stainless steel seamless tube, and the gaps are densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. This structure is not only advanced, high thermal efficiency but also generates uniform heat. When a current flows through the wire, the heat generated is diffused to the surface of the metal tube through the crystalline magnesium oxide powder, and then transferred to the heated part of the air to achieve the purpose of heating.

   Features of heating tube:

1. Most of the hot air circulates in the box, with high thermal efficiency and energy saving.

2. Using the effect of forced ventilation, there is an adjustable air distribution board in the box, and the material is dried evenly. The heat source can be steam, hot water, electricity, far infrared, and a wide range of choices.

3. The whole machine has low noise and stable operation. Automatic temperature control, convenient installation, and maintenance.

4. It has a wide range of applications and can dry various materials. It is universal drying equipment.

   Application range of heating tube:

The hot-air circulation oven is suitable for heating, curing, drying and dewatering of materials and products in the pharmaceutical, chemical, food, agricultural and sideline products, aquatic products, light industry, heavy industry, and other industries. Such as raw materials, traditional Chinese medicine, traditional Chinese medicine decoction pieces, extracts, powders, granules, granules, water pills, packaging bottles, pigments, dyes, dehydrated vegetables, dried melons and fruits, sausages, plastic resins, electrical components, baking paint, etc.

The main technical parameters and related instructions of the hot air circulation oven:

1. The heating source is steam, electricity, far-infrared, and electric steam for users to choose from.

2. Use temperature: steam heating 50～140℃, even up to 150℃.

3. Electricity and the far-infrared temperature is 50～300℃.

4. The usual steam pressure is 0.2～0.8Mpa (2～8KG).

5. There are three kinds of materials: carbon steel, aluminum plate, and stainless steel.

  The strong blast circulation system with a unique design ensures the stability of temperature. The temperature control system adopts digital display temperature control, which is intuitive and eye-catching. It is equipped with a reliable protection device and an over-temperature alarm. For special requirements, the imported production line can be designed and customized for users.
