The core advantage of vacuum spiral dryer in the pharmaceutical industry lies in itsLow temperature vacuum environmentThis can effectively avoid the damage of high temperature to thermosensitive drug components, especially suitable for processing temperature sensitive materials such as biological products, enzyme preparations, and traditional Chinese medicine extracts.

Its working principle is to stir the material and conduct heating through a screw conveyor under vacuum conditions, so that the moisture evaporates rapidly at low temperatures. This drying method canSouth ChengduRetain the active ingredients and stability of the drugAt the same timeExtend shelf life, andImprove the solubility and bioavailability of drugs.

Vacuum spiral dryer is an efficient conductive drying equipment, mainly used for drying and processing heat sensitive, flammable and explosive materials. Its core working principle is to move the material through the rotation of the screw conveyor in a vacuum environment, while using the heating medium (such as steam, thermal oil) introduced through the hollow shaft, blades, and jacket for heat conduction, so that the moisture in the material evaporates at low temperatures.

The specific workflow is as follows:

1. ‌Establishment of vacuum environmentVacuumize in a sealed drying chamber to lower the boiling point of water and make it easier for water to evaporate.

2. ‌Material conveying and mixingSpiral blades rotate, constantly pushing the material forward while stirring, to evenly heat the material and avoid clumping and drying dead corners.

3. ‌Thermal conduction dryingHeat is conducted to the material through hollow shafts, blades, and jacket walls, accelerating the vaporization of water. The vaporized water vapor is extracted by the vacuum system.

4. ‌Continuous operationSome models adopt a multi compartment design, which can independently control temperature, achieve continuous feeding and discharging, and improve drying efficiency.

This equipment is widely used in industries such as chemical, food, and medicine, and is particularly suitable for dehydration and drying of liquid, slurry, paste, powder, and other materials.
