The vacuum drying unit is designed to dry heat-sensitive, easily decomposable and easily oxidized materials, and can be filled with inert gas. In particular, some of the components with complex composition can also be rapidly dried. Low oxygen content when drying under low pressure can prevent oxidation and deterioration of the material to be dried. It can dry dangerous materials that are flammable and explosive. It can vaporize the moisture in materials at low temperature, and it is easy to dry heat-sensitive materials. It can recover the materials in the dried materials. Valuable and useful ingredients; can prevent the release of toxic and hazardous substances from the dried material and can be an environmentally friendly type of "green" drying.
Compared with the current commonly used oven drying method, spray drying method, etc., the vacuum continuous dryer is a product that can guarantee the product quality is much higher than other drying methods.
Industry insiders pointed out that domestic companies have accelerated the study of vacuum drying technology, which has reduced energy consumption to a certain extent, reduced pollution, brought more benefits and value to society, and made due contribution to the realization of green production and low-carbon production. contribution.
At this stage, however, the vacuum dryer revolution in China has not yet been successful. Vacuum drying equipment manufacturers generally have low innovation capabilities. Poor enterprises that can introduce new technologies and new products with independent intellectual property rights have resulted in slow development of drying technologies. Knowledge achievements have not been effectively translated into actual productivity. At present, the R&D and innovation of technologies in the field of drying equipment mainly rely on universities and research institutes. Due to the disconnection of companies, it is difficult to effectively turn knowledge achievements into productivity.
It can be seen that in this regard, China's relevant enterprises should carry out comprehensive, multi-level energy-saving technological transformation, vigorously develop the application of renewable energy and industrial waste heat drying technology, and comprehensively promote China's vacuum drying technology reform and application.
Vacuum drying equipment accelerates research on energy saving and environmental protection technology and wins favor from the market
After more than ten years of development, the technical level of the drying equipment industry has been continuously improved. China's drying equipment industry has begun to enter a more mature stage, and it can better meet the actual needs of users in various fields. Vacuum drying equipment is favored by the market because of its "green" advantages.
