Many types of vacuum drying equipment have a wide range of applications and rapid development. In this document, there are only a few domestic and international developments of vacuum drying equipment, in order to achieve information exchange, to determine the problem of the development of vacuum drying equipment to be solved, and to improve the level of my vacuum drying machine.
There are many advantages to vacuum drying: when the drying voltage is low, the oxygen content can be dried to prevent oxidation and deterioration; the material can be flammable and explosive; the material can be evaporated at low temperature, and the heat can be easily dried Sensitive materials; can recover valuable and useful components of dried materials; can be environmentally friendly type of "green" drying to prevent the discharge of toxic and harmful substances from dried materials.
Therefore, the application of vacuum drying equipment is increasing. The main disadvantage of vacuum drying is that a vacuum system for pumping water vapor is required, which makes the cost of equipment investment high, and the operating cost is high; the equipment has low productivity and small output. In order to overcome these shortcomings, some skilled workers, many efforts.
At the same time, there are many advantages to vacuum drying, and there are vacuum drying equipment for some products. Therefore, the development of vacuum drying equipment will be promising.
