物の乾燥度の調節が極めて面倒である欠陥がある。Conventionally, in a vacuum dryer, the method of measuring the moisture content (dryness) of materials to be dried such as fibers and grains is to measure the temperature of the materials to be dried, and to determine the relationship between this temperature, the properties of the materials to be dried, and the degree of vacuum. One method is to measure the vacuum level in the drying process to obtain a vacuum curve over time, and then empirically measure from this vacuum curve. There are methods known to measure water content by subtracting it from the moisture content before treatment, but the first two methods cannot be used in vacuum dryers that use high frequency as a heat source, and the degree of dryness of the material to be dried is extremely difficult to adjust. There are flaws that are bothersome.

After opening the vacuum drying tank (1) at 71 and creating a vacuum inside the vacuum drying tank (1), vacuum drying is performed using the high frequency electrode plate (31 (161) as a heat source. When the truck (4) is lifted up, the truck (4) is supported by the support rod (121 [151, so this is detected by the load detector 03), its weight is measured, and the weight is measured. The moisture content of the dried material is measured based on the weight change of the dried material due to evaporation during the drying process.
