Vacuum dryer, the oxygen content is low when drying under low pressure, can prevent oxidation and deterioration of the material to be dried, can dry dangerous goods that are flammable and explosive; can vaporize the moisture in the materials at low temperature, easy to dry heat-sensitive materials; can be recycled The valuable and useful ingredients in the dried material can prevent the release of toxic and hazardous substances from the dried material and can be an environmentally friendly type of green drying.
However, at this stage, the vacuum dryer revolution in China has not yet been successful, and efforts still need to be made. 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.
Drying is one of the process units with relatively high energy consumption. In the current environment where energy conservation and environmental protection are increasingly valued, different energy prices are becoming more reasonable, and users are increasingly demanding the quality of the material drying, vacuum drying at a low temperature A new type of drying technology that is energy-efficient, environmentally friendly, and of good drying quality is bound to have excellent opportunities for development.
Vacuum low-temperature drying equipment manufacturers should seize and make full use of this opportunity to make continuous progress under the joint efforts of government departments, industry, and academia. To achieve the three goals of quality, energy saving and environmental protection, and constantly enhance the market competitiveness of the equipment.
With the improvement of the people's production level and the rapid development of industry, commerce, service industry and emerging industries, the application of drying devices will become more and more extensive, and the requirements for the quality of dried products will also become higher and higher. Drying is not an independent process. It requires dehydration and drying in the process, and its purpose is to adjust the quality of the material.
