Drying is one of the ways to keep substances from spoilage. There are many drying methods, such as sun drying, boil drying, drying, spray drying and vacuum drying. However, these drying methods are all carried out at temperatures above 0°C or higher.The lyophilization process includes three stages: pre-freezing, sublimation and re-lyophilization. Reasonably and effectively shortening the freeze-drying cycle has obvious economic value in industrial production.

Attention should be paid to the use of: during vacuum distillation, when the temperature is high and the vacuum degree is high, the liquid in the bottle may boil. At this point the vacuum should be lowered to allow for smooth distillation. When the evaporation is stopped, first stop heating, then stop vacuuming, and finally cut off the power supply and stop rotating.

What should I pay attention to when purchasing a vacuum drying oven? As a kind of equipment widely used in various industries, drying oven is not only rich in variety, but also has mature technology. Many manufacturers can produce it, which leads to a mixed bag in the market, which is a good source for our purchase. For the inconvenience, the following will explain how to choose a vacuum drying box.
