Low Temperature Pulse Vacuum Drying Oven Suitable For Heat-sensitive Materials

Low Temperature Pulse Vacuum Drying Oven Suitable For Heat-sensitive Materials

Description:

Our pulse vacuum dryer is optimized for drying heat-sensitive raw materials, widely applied in pharmaceutical, herbal extraction, food additive and fine chemical industries. Different from conventional static vacuum dryers, it adopts periodic vacuum pulse ventilation structure to accelerate internal moisture migration, greatly shorten drying cycle while maintaining low operating temperature from 40℃ to 75℃, effectively prevent active ingredients from thermal degradation, oxidation and volatilization loss.

The main chamber adopts full stainless steel contact structure, complying with pharmaceutical GMP production standards. The sealed heavy-duty door is equipped with observation windows for real-time operation monitoring. Internal heating plates provide uniform heat distribution, the whole machine runs under vacuum environment to lower solvent boiling point, so water and organic solvent can evaporate rapidly at low temperature.

Water boils at 100℃ under normal pressure; after vacuuming, the chamber pressure decreases, and the boiling points of water and organic solvents decrease simultaneously, allowing solvent vaporization and evaporation to occur at low temperatures of 40–75℃. This is suitable for heat-sensitive materials such as antibiotics, traditional Chinese medicine extracts, and enzyme preparations, avoiding the destruction of active ingredients by high temperatures. The equipment is equipped with a heating tray/plate, using hot water or heat transfer oil as a heat source. Heat is transferred to the material through heat conduction, causing the moisture inside the material to absorb heat and turn into water vapor. The vacuum pump continuously extracts the water vapor from the chamber, maintaining negative pressure, allowing the moisture in the material to continuously migrate and escape, completing the drying process.

Application:

It is suitable for drying API, enzyme preparation, Chinese medicine extract, probiotics, sugar and natural pigment materials. Customized chamber size,And heat-sensitive materials that are prone to decomposition and polymer degradation at high temperatures. heating medium and vacuum system configurations are available to match different batch production demands, stable performance reduces material rejection rate and improves overall production efficiency.

Specification:

Feature Advantage:

1. Utilizing vacuum pressure reduction to lower the solvent boiling point, dehydration can be completed at 40–75℃ without high-temperature heating.

2. Periodic micro-air intake + vacuuming breaks through the water vapor retention layer on the material surface, accelerating the migration of deeper moisture.

3. The entire system operates in an intermittent, closed-loop manner, resulting in high heat utilization.

4. Drying temperature, vacuum level, and pulse interval can be freely set; chamber size, heating medium, and vacuum unit can all be customized.

5. The interior is flat with no dead corners, making it easy to clean and sterilize, and it meets the production requirements of the pharmaceutical and food industries.
