Products Description
The SED-36WB-K uses microwave heating under vacuum to remove moisture from tray-loaded materials. It is intended for low-temperature drying of heat-sensitive products, including food ingredients, herbal extracts, and selected pharmaceutical or chemical materials. Suitable operating settings depend on the composition of the feed and the moisture level required in the dried product.
Heating and moisture removal
The vacuum system lowers the pressure in the chamber, allowing moisture to evaporate at a lower temperature. Microwave energy is absorbed within the material and converted into heat. The tray assembly rotates to move the load through the microwave field. Operators can adjust the microwave output to suit the stage of the drying cycle and use the temperature indication to monitor the material.
The machine uses a water-ring vacuum pump. Cooling water removes heat from the microwave generators, and the system monitors cooling-water flow and temperature. An infrared measurement system reads the product temperature at a fixed position as the tray assembly turns. The control interface brings process settings and operating indications together for the operator.
Loading and process monitoring
The chamber door provides access to the tray assembly. The drive positions the trays at the door during loading and unloading. The tray support includes a balancing mechanism designed to keep trays level as the assembly turns, which is useful when drying a liquid or paste that needs to remain evenly distributed.
A camera and viewing port let operators observe the product while the chamber is closed. The drying settings can be reviewed against the behavior of the material during processing. After unloading, the operator can check the condition of the dried material and adjust the settings for subsequent batches using the same feed and tray arrangement.
