Progress vacuum drying apparatus conventional vacuum drying device they use heat conduction, convection or thermal radiation heating way, heating slow and not uniform, in recent years, researchers vacuum technology and microwave technology and other drying technology combined with vacuum dryer, there are some new types of vacuum drying device. Vacuum freeze-drying, the product placed in a vacuum chamber, located between two heated plates, using a low temperature stimulate far-infrared heating How to choose a vacuum dryer, to ensure even drying temperature of the heating plate according to the heating curve is precisely controlled drying process. Select the vacuum to be able to ensure that the entire drying process are all water-insoluble form of ice melt and a vacuum dryer Changzhou Which is best for the majority of vegetables and meat, the choice of 0.5 ~ 1Pa, corresponding to 25 ℃ sublimation temperature of about fitness. Quality vacuum dryer vacuum dryer _ _ and being dried by Changzhou City Drying Equipment Co., Ltd. and positive.
