Changzhou City of dry Drying Equipment Co., Ltd. to high-quality products, fast delivery, so that every customer satisfaction is our eternal commitment. When the vacuum dryer operation, the first agitator, adding the dried material, iron nitrate and drying equipment, and charging port closed. At the same time pass into the steam heating, heating steam pressure is generally 0.2 ~ 0.4Mpa (gauge pressure). Vacuum extraction with water vapor and non-condensable gases, generally dry material, a vacuum of about 700mmHg. Evaporation strength of this dryer, with the material properties, the humidity, steam pressure and vacuum degree varies. For example, potassium cyanate drying equipment, vacuum degree of 700mmHg, heating steam pressure is 0.2Mpa (gauge pressure), the potato starch from the initial moisture of 40% to 20% dry, iron drying equipment, drying machine evaporation intensity of 5 ~ 7 kg / m2 · h. Changzhou City of dry Drying Equipment Co., Ltd. Enterprise spirit "division of labor, regardless of family": unity and cooperation, against all odds, drying equipment, to create a brilliant team. Advantages of vacuum drying: drying at low pressure oxygen content is low, can prevent oxidative deterioration of dry materials, can be dried explosive dangerous goods; the material moisture can vaporize at low temperatures, easy drying heat sensitive materials; energy recovery dried material is valuable and useful ingredients; dry material to prevent toxic emissions of harmful substances, can become environmentally friendly types of "green" dry. Therefore, the application of vacuum drying equipment is widely used. Ammonium nitrate drying equipment drying equipment _ _ force dry and dried by dry Changzhou City Drying Equipment Co., Ltd..
