Changzhou source Kwong Wah Drying Equipment Co., located in the birthplace of China drying equipment industry - Coke Town Changzhou Wujin District, adjacent to the Beijing-Shanghai high-speed, the Shanghai-Nanjing Railway, the Shanghai-Nanjing Expressway Yokoyama Crossing three kilometers, a vacuum dryer, the main production : drying, mixing, granulating equipment. Double cone rotary vacuum dryer classic double cone rotary vacuum dryer is raw material drug production equipment is widely used, which is due in a vacuum drying process, the pressure cylinder body is always lower than the atmospheric pressure, a small number of gas molecules, low density, low oxygen, which can dry and easy oxidative changes in drug production, buy a vacuum dryer, can reduce the chance of material contamination. But also because of the vaporization process, the temperature and vapor pressure is proportional to the water, so when the vacuum dried material in the water can be vaporized at low temperatures, reaching low-temperature drying, especially for the production of drugs in heat-sensitive materials. At the same time, eliminate atmospheric vacuum drying hot air drying and easy to produce surface hardening phenomenon, which is a large pressure difference between the vacuum dried material and surface, under pressure gradient effect, and soon moved to the surface of the water, surface hardening does not occur. Further vacuum drying, the temperature gradient between the interior and exterior material is small, so that the reverse osmosis and to collect its own vehicle can move, effectively overcome the phenomenon of separated solvent resulting hot-air drying.

(1) The situation (such as material shapes, sizes, piling method) is dried material, the material itself, the moisture content, density, viscosity and other properties. Generally, the material fine particles and uniform, piling loose, thin, normal temperature vacuum dryer, the internal water easily spread. If the increase in the initial temperature of the material, by vacuum filtration pre-treatment, to reduce the moisture content and other materials, a large vacuum dryer, vacuum drying rate could increase. (2) the higher the degree of vacuum, the more conducive to water vaporized at a lower temperature, but too high negative vacuum thermal conductivity, the material will affect the heating effect. To improve the speed of drying, vacuum degree should be considered depending on the characteristics of the material. Typically, the vacuum should not be less than 1 × 104Pa.
