Abstract
This article presents results on research and manufacturing of a seafood-drying device using a vacuum environment combined with a microwave heat source. We produced a microwave vacuum drying device with parameters of a 2kg/batch drying capacity, using a heat source from a microwave with a capacity of 1000W. The device's microwave power can be adjusted from 100W to 1000W, combined with a vacuum environment to prevent oxidation and sterilization and increase the moisture removal rate of dried materials. The device can reach a vacuum environment of 270 Pa. The dehumidifying device has a capacity of 1.0 HP. Moreover, this device is equipped with automation that uses temperature, humidity, and pressure measuring devices to control the device.
