Vacuum belt dryer is a common drying equipment widely used in chemical, pharmaceutical and food industries. It uses a vacuum environment and belt transmission to quickly dry wet materials and improve production efficiency. This article will reveal the working principle of the vacuum belt dryer and let you understand its secrets.

The working principle of the vacuum belt dryer is based on the evaporation drying process in a vacuum environment. First, the wet materials are evenly spread on the conveyor belt, and then the conveyor belt transports it to the vacuum-sealed drying chamber. In the drying chamber, a vacuum pump is used to reduce the pressure inside the drying chamber to a lower level, allowing the moisture to evaporate quickly at a lower temperature. In this way, the moisture in the wet material is quickly evaporated and removed, thereby achieving a rapid drying effect.

Compared with traditional hot air drying, the vacuum belt dryer can dry at a lower temperature, effectively avoiding problems such as deterioration and oxidation of materials caused by high temperatures. In addition, the vacuum belt dryer can also reduce the pollution of materials by oxygen and air during the drying process, and maintain the color and aroma of the materials. It is especially suitable for industries with high product quality requirements.

In addition, the vacuum belt dryer also has the advantage of continuous production, which can achieve rapid and continuous drying of materials and improve production efficiency. In the food industry, vacuum belt dryers are often used to dry vegetables, fruits, meat and other products to maintain the nutritional content and taste of the products. In the pharmaceutical industry, vacuum belt dryers are also widely used in the drying and granulation process of drugs to ensure product stability and quality.

Through the introduction of this article, I believe you have a deeper understanding of the working principle of the vacuum belt dryer. It uses a vacuum environment and belt transmission to dry wet materials quickly and continuously, maintaining the quality and nutritional content of the product. Vacuum belt dryers play an important role in the chemical, pharmaceutical and food industries, providing efficient and reliable drying solutions for production.
