The twin-conical rotary vacuum dryer exhibits the following characteristics:
During the vacuum drying process, the pressure inside the cylinder is always lower than atmospheric pressure, resulting in fewer gas molecules, lower density, and reduced oxygen content. Consequently, it is suitable for drying drugs prone to oxidation, minimizing the chance of material contamination.
(2) Due to moisture content inVaporizedDuring the process, the temperature is directly proportional to the steam pressure.Vacuum DryingAt low temperatures, the moisture in the material can vaporize, achieving low-temperature drying, particularly suitable for applications that require...Thermally sensitive materialsPharmaceutical production.
(3) Vacuum drying can eliminate atmospheric pressureHot air dryingSurface hardening phenomenon prone to occur, due to the large pressure difference between the vacuum-dried material and its surface.Pressure GradientUnder the action, moisture quickly migrates to the surface without causing surface hardening.
(4) Due to the vacuum drying process, there is a difference between the internal and external materials.Temperature gradientSmall, due toReverse OsmosisThe function allows moisture to move and collect independently, effectively overcoming the dispersion phenomenon caused by hot air drying.
