Vacuum Microwave Dryer is designed for low-temperature drying of herbal extracts and extract pastes. It provides fast, uniform drying under vacuum while helping preserve heat-sensitive active ingredients, color, and quality.
Our industrial vacuum microwave dryer is designed for efficient and low-temperature drying of herbal extracts, traditional Chinese medicine extracts, plant extracts and other extract pastes. By combining vacuum technology with microwave heating, the machine can accelerate moisture removal at a relatively low temperature while helping preserve heat-sensitive active ingredients, color and product quality. It is suitable for drying concentrated herbal paste into dried blocks, granules or powder for further processing. Different microwave power, chamber capacity and drying configurations can be customized according to the material characteristics, initial moisture content and required production capacity.

The vacuum microwave drying equipment combines 2450 MHz industrial microwave technology with vacuum low-temperature drying for efficient and controlled moisture removal.
The integrated system includes a microwave heating chamber, vacuum system, cooling system, condensation recovery unit, intelligent control, temperature monitoring, and safety protection. Microwave power can be adjusted according to different materials and drying stages, providing flexible process control and stable operation.
By combining internal microwave heating with a low-pressure environment, the system enables efficient drying at lower temperatures and is suitable for the dehydration and processing of various materials.
Low-Temperature Drying
Vacuum conditions reduce the boiling point of water, allowing extract paste to be dried at lower temperatures.
Fast Drying Speed
Microwave heating acts directly on the material, accelerating moisture removal and shortening drying time.
Preserves Active Ingredients
Low-temperature and rapid drying helps reduce thermal damage to heat-sensitive components in herbal extracts.
Uniform Heating
Microwave energy heats the material internally, helping improve drying uniformity and reduce uneven moisture.
Good Product Quality
Helps preserve the original color, aroma and quality of herbal and plant extracts.
Efficient Moisture Removal
The combination of vacuum and microwave technology improves water evaporation efficiency, especially for high-moisture extract pastes.
Easy Process Control
Microwave power, vacuum level, temperature and drying time can be adjusted according to different materials.
Customized Solutions
Machine capacity, microwave power and chamber configuration can be customized according to the material and required production capacity.
