Vacuum drying has the advantages of low risk and easy control compared with microwave drying.

　　Pharmaceutical Network Technical Article: Drying is a very common process in the pharmaceutical production process Recently, some netizens asked, "Which is better for vacuum drying and microwave drying?" Which production speed is fast? Does vacuum drying have any effect on quality if it changes to microwave? The industry response said that vacuum drying and microwave drying are mainly based on the product, considering cost and efficiency, as well as the impact on quality However, vacuum drying is mainly used in new product research, change the drying mode is a big change, need to be carefully considered, suggested to consider the actual significance, specifically depends on the nature of the variety, if the significance is not necessary to change
Others in the industry pointed out that, in fact, compared with vacuum drying, microwave drying risk is much larger, also difficult to control, it is recommended not to choose microwave first do not choose
It can be seen that the advantages of vacuum drying, in recent years, with the rapid development of medicine, food and other industries, vacuum drying technology and related equipment has also been widely used
For example, the vacuum drying tank is a negative pressure equipment, the use of the vacuum state of moisture steam speed, low boiling point of the principle of different products drying, than the traditional high temperature drying effect is good, fast, low energy consumption At present, vacuum drying tank applications are widely used, including vacuum puffing, vacuum impregnation and other treatment, used in wood, food, transformers, food and other different products drying
Vacuum drying box is one of the important auxiliary drying equipment in experiment, and has a wide range of applications This is designed for dry thermal, easy to decompose and easy to oxidize substances, work can maintain a certain degree of vacuum in the work room, and can be filled with inert gases, especially some complex components can also be quickly dried, the use of intelligent digital temperature regulator for temperature setting, display and control, is currently used in the pharmaceutical, food industry
In addition, depending on the structure, the vacuum drying equipment also has a difference Among them, the box vacuum dryer is suitable for low-temperature drying of hot-sensitive materials that are easy to decompose, polymerize and spoil at high temperatures, and is widely used in pharmaceutical, chemical, food, electronics and other industries The swing vacuum dryer has been widely used in fine chemical industry, medicine and so on, and does not apply to materials with high viscosity or strong adhesion during the swing process The equipment is mainly used in pharmaceutical, chemical, food and other industries of powder, granular and fiber-like materials concentration, mixing, drying and need to be low-temperature drying materials (such as biochemical products, etc.), more suitable for oxidation, volatility, thermal stimulation, toxic materials and not allowed to destroy crystal materials drying
It is worth mentioning that in recent years, with the continuous promotion of energy conservation and environmental protection policies, how to save energy efficiency has become the pursuit of many users, in this context, vacuum drying equipment also needs to be upgraded towards the direction of energy conservation, to help users improve efficiency, save costs It is reported that at the 57th Pharmaceutical Machine Exhibition, there are enterprises with new research and development of intelligent vacuum dryer, which is a vacuum technology and thermal heat replacement technology combined with high vacuum new intelligent drying equipment, suitable for thermal materials, easy to decompose, easy to oxidize materials, high sugar content, low temperature, easy to spill, easy to foam dip paste, and can meet the requirements of energy conservation.
