Vacuum drying is based on a fundamental principle: the water saturation vapor pressure and temperature are closely related drying equipment suppliers, in a vacuum, the boiling point of water is reduced, that is, operating at low temperatures under vacuum operation at high temperatures can be avoided sabotage vitamins and other nutrients, while improving the drying speed. Also in the vacuum system, the volume of air per unit content is below atmospheric content, at this relatively hypoxic environment for food drying can reduce or even avoid the chance of fat oxidation in foods, pigments and other browning or other oxidative deterioration, Therefore, the use of vacuum-dried to obtain a better quality of food. Box-type vacuum dryer canister vacuum drying is the oldest line drying equipment, but also the most simple of a vacuum dryer, how hollow block heating plate in a vacuum oven drying equipment, heating plate which in general through steam heating can also be heated electrically or other radiant heating. Material placed on the metal plate inside the heating plate drying equipment Which is good, the heat conduction through the heat to reach the interior materials, so the water is heated to evaporate. Box-type vacuum dryer currently used in practice is still widespread, suitable for drying liquid, paste, powder and granular food materials. Which is good drying equipment, drying equipment, and are dried to provide professional advice and are provided by Changzhou Drying Equipment Co., Ltd .. Changzhou and now Drying Equipment Co., Ltd. (www.hzdrying.com) strong, credible, in Changzhou, Jiangsu drying equipment industry has accumulated a large number of loyal customers.
