Process method for high-vacuum drying and dewatering

The invention relates to a high-vacuum drying and dewatering process method, which is more suitable for a moisture removal principle mechanism compared with a traditional breathing type baking and dewatering method of'frequent and multiple switching of dry air conveying and vacuum 'in the industry, and can save multiple switching of filled dry air and heat taken away by the dry air. The drying gas cost and the heat loss of the baking process are reduced, and the energy-saving and cost-reducing concept of the current manufacturing industry is better met; meanwhile, due to the fact that multiple times of dry gas intervention time are omitted, the vacuum holding time accounts for the most proportion of the whole drying and dewatering period, the drying and dewatering speed can be greatly increased, the processing time is effectively shortened, the manufacturing cost and the shared energy consumption cost are reduced, the equipment utilization rate is increased, and the equipment purchase cost is reduced. 本发明涉及一种
