Materials Suitable for Microwave Vacuum Drying
How Microwave Vacuum Drying Works
Under vacuum, moisture can evaporate at a lower temperature. Microwave energy acts directly on polar molecules within the material, generating heat inside the product and at its surface without relying only on external heat conduction. The material trays rotate slowly to improve microwave exposure across the cabinet. During the process, the vacuum system removes moisture vapor while temperature, operating time, vacuum conditions, and cooling-water status are monitored and controlled.

Key Features
| Feature | Customer Value |
| Stepless Microwave Power Control | Microwave output can be adjusted to match different materials and drying stages, supporting more stable processing and energy use. |
| Rotating Tray System | The trays rotate slowly inside the cabinet to improve microwave exposure and reduce temperature differences between loading positions. |
| Industrial Water-Cooled Magnetrons | Industrial-grade 1.05 kW magnetrons use direct water cooling and are designed for long continuous operating periods. |
| Infrared Temperature Measurement | Fixed-point infrared temperature measurement supports timely material-temperature monitoring and more accurate process control. |
| Real-Time Process Observation | Electronic monitoring and vacuum sight glasses allow operators to observe material condition and drying progress during operation. |
| Cooling-Water Protection | Cooling-water flow and temperature are monitored to reduce the risk of magnetron damage caused by blockage, insufficient flow or excessive water temperature. |
| PLC and HMI Control | Operators can enter basic process parameters through the human-machine interface. Microwave power and drying time can then be managed through the automatic control system. |
| Positioned Loading and Unloading | The tray positioning mechanism returns the loading rack to the discharge position, making tray handling and cleaning more convenient. |
Model Positioning
Information Required Before Model Selection
Select the dryer according to the required water-removal rate and process conditions rather than only the weight of material loaded per batch. To prepare a model recommendation, please provide the material name and form, batch weight, initial moisture, target moisture, maximum allowable product temperature, tray-loading thickness, required drying time, available power supply, cooling-water conditions and installation space.
- Material name and physical form
- Batch weight or hourly feed requirement
- Initial and target moisture
- Maximum allowable product temperature
- Tray-loading thickness and particle size
- Required cycle time or water-removal rate
- Factory voltage and cooling-water conditions
- Available floor space and cleaning requirements
Typical Operating Process
- Load the prepared material evenly into the trays and place the trays on the rotating rack.
- Close the chamber and start the vacuum system according to the approved operating procedure.
- Enter the drying time, microwave power and temperature-related parameters through the HMI.
- Start tray rotation and microwave heating. Monitor material condition, temperature, vacuum and cooling-water status.
- Adjust the process settings when required by the validated material recipe.
- At the end of the set process time, stop heating, release vacuum safely and unload the trays.
Key System Components
The system is built around a SUS304 microwave heating cabinet, rotating tray rack, microwave power modules, vacuum pipeline, cooling-water circuit, temperature-control system, PLC/HMI control, observation devices and safety monitoring components. Final configuration varies by model and project scope.
Material and Installation Examples
The technical files include drying examples for fruits, vegetables, herbs, botanical materials, grains, concentrates and paste-like materials, together with installation-site photographs. These images can be reused as supporting evidence, but each gallery image should identify the material and clarify that final results depend on the customer’s formulation and target moisture.
FAQ
| Q: What is the difference between SED-3.6WB-K and SED-60WB-K? |
| A: The SED-3.6WB-K provides 0–3 kW microwave output and 2.4–3.6 kg/h dehydration capacity, while the SED-60WB-K provides 60 kW output and 48–60 kg/h dehydration capacity. The correct model depends on the required water-removal rate, batch size and factory utilities. |
| Q: Can the machine dry herbs, extracts and food materials? |
| A: Yes. The listed applications include medicinal extracts, herbal materials, pharmaceutical and health-care products, food ingredients and other heat-sensitive materials. A material test is recommended before the final process and machine configuration are confirmed. |
| Q: How does the machine improve drying uniformity? |
| A: Microwave power is adjustable and the trays rotate slowly inside the cabinet. This helps improve microwave exposure across different tray positions and reduce temperature differences. |
| Q: How is material temperature monitored? |
| A: The system uses infrared fixed-point temperature measurement. Process temperature should be confirmed according to the material characteristics and the validated drying recipe. |
| Q: What utilities are required? |
| A: Both listed models use 380 V / 50 Hz three-phase five-wire power. Cooling-water supply, drainage, ventilation, installation space and other utilities should be confirmed according to the selected model. |
| Q: Can the system process liquid or paste-like materials? |
| A: The SED-60WB-K technical description includes a self-locking mechanism intended to keep liquid material trays balanced. Final suitability, tray loading and anti-spill measures must be confirmed for the specific material. |
| Q: What information is needed for a quotation? |
| A: Please provide the material name, physical form, batch weight, initial and target moisture, temperature limit, required drying time, local voltage, cooling-water conditions and available installation space. |
