Vacuum oven principle: high efficiency and low energy consumption drying sharp

in the traditional drying method, often using high temperature, steam, hot air and other ways, so not only high energy consumption, high cost, but also may destroy the internal nutrients or pharmaceutical ingredients. In contrast, the vacuum oven uses a new type of drying method, that is, in a vacuum environment, by reducing air pressure and moisture pressure, to accelerate the drying of items.

vacuum oven is equipped with a vacuum pump system. By starting the vacuum pump, the air inside the oven is pumped out to form a vacuum environment. In a vacuum environment, the boiling point of water is also reduced, so that the water on the surface of the article evaporates rapidly, and the drying speed is much faster than the general drying method. Heating can also be used to further accelerate the speed of drying, which requires much lower energy than traditional drying methods, which can greatly reduce drying costs.

vacuum oven is widely used, especially in food, medicine, chemical, electronics and other industries, so it is also called "industrial dryer". In the food industry, vacuum ovens are often used in the drying of beef jerky, banana slices, maltose, seaweed, etc. This way can retain the nutrients of food, but also delicious. In the pharmaceutical industry, the vacuum oven can reduce the water content of the drug to a specified ratio to ensure the stability of the drug and extend the shelf life. In the chemical industry, the vacuum oven can separate the moisture in various chemicals to ensure the quality of the product.

vacuum oven not only has the characteristics of high efficiency, low energy consumption and good drying effect, but also has the advantages of simple operation and no cost. Therefore, it is also widely used in some laboratories and scientific research, for preparing samples, drying chemicals, etc.

vacuum oven as a new drying method, the future will have a wider range of applications. In the realization of environmental protection, energy saving today, high efficiency and low energy consumption of vacuum oven will become the new darling of the industry.
