vacuum hot air circulation drying equipment

The vacuum hot air circulation drying equipment increases the saturated vapor pressure of water in the environment where the coil insulation material is located by vacuuming, making it easier for it to evaporate from the insulation paper. During this period, it is continuously heated and the temperature is increased to ensure the gasification energy of water and make it easier for water to be discharged.

In modern industrial production, drying is an indispensable and important link, and vacuum hot air circulation drying equipment is becoming the preferred choice for more and more enterprises due to its excellent performance and wide application fields.


1, Principle of Vacuum Hot Air Circulation Drying Equipment

The vacuum hot air circulation drying equipment adopts the principle of hot air circulation in a vacuum environment, which lowers the boiling point of water by reducing the air pressure, allowing the material to quickly evaporate moisture at low temperatures. The equipment mainly consists of a vacuum system, a heating system, a circulating fan, a drying chamber, a control system, etc. During operation, the vacuum pump pumps the drying chamber to a vacuum state, the heating system provides a heat source, and the circulating fan circulates hot air in the drying chamber, uniformly heating the material and removing evaporated moisture, thereby achieving rapid drying of the material.

2, Advantages of vacuum hot air circulation drying equipment

Efficient drying: In a vacuum environment, the boiling point of water decreases, the evaporation rate of material moisture accelerates, the drying time is significantly shortened, and the production efficiency is significantly improved.

Low temperature drying: In a vacuum environment, materials can be dried at lower temperatures, effectively avoiding the deterioration of heat sensitive materials due to high temperatures and maintaining the active ingredients and quality of the materials.

Uniform drying: The hot air circulation system ensures uniform temperature in the drying chamber, uniform heating of materials, consistent drying effect, and avoids local overheating or uneven drying.

Energy saving and environmental protection: In a vacuum environment, the specific heat capacity of hot air decreases, the heat utilization efficiency increases, and energy consumption is significantly reduced. At the same time, a vacuum environment can effectively prevent material oxidation and pollution, reduce exhaust emissions, and be more environmentally friendly.

Easy to operate: The equipment adopts an automated control system, which is simple and convenient to operate. Drying parameters can be set according to different materials to achieve intelligent control.
