Vacuum freeze-drying water, there are three state of aggregation vacuum drying equipment, namely liquid, solid and vapor. With the pressure is reduced, the change is not fzg freezing vacuum oven, and more and more low boiling point side, closer and closer to the freezing point. When the pressure drops below a certain value, the boiling point and freezing point that is combined with the solid ice directly without passing through a liquid into vapor. Triple point of water pressure 610.5Pa, triple point temperature of 0.0098 ℃, what pressure below the triple point pressure in the vacuum drying principle is that the solid ice can absorb heat directly into steam vapor state, freeze-dried principle in this. Belt type continuous vacuum drying equipment produced by the production of Japan's Osaka WL-VAQ-belt type continuous vacuum drying equipment, suitable for liquid material, muddy, paste sued concentration and a high viscosity boring and dry. Japan Okawa Production of original strain BV-100.5-type vacuum belt continuous drying apparatus, steam and conduction heating, the temperature of each section is adjustable, belt tensioners and speed adjustable. Swiss Bucher - Gade has developed a series of belt-type continuous vacuum drying equipment, with automatic cleaning device. _ Use of vacuum drying and vacuum drying being dried _ provided by the Changzhou City Drying Equipment Co., Ltd. and positive. Changzhou City Drying Equipment Co., and positive (www.hzdrying.com) Sanhekou Industrial Park in Changzhou. Scraps and development in the wave of market economy, currently being dried and has a high profile in the drying device, enjoy a good reputation. And n-dried to obtain the whole network business alliance certification, marking our service and management level has reached a new height.
