Embodiment Construction
[0044] In the drying process, for a closed drying container, as a closed system, its system volume is a constant, so its thermodynamic state is an isochoric process.
[0045] The invention provides a method for measuring the moisture content of the dried object during the vacuum drying process, that is, by timely sealing the drying container during the vacuum drying process, so that the drying system enters an isovolumic state, and based on the isovolumic process Thermodynamic state, a new method for real-time measurement of the moisture content of the dried material established.
[0046] The method for measuring the moisture content of the dried object according to the present invention is used to calculate the water content of the dried object in the drying container during the vacuum drying process, and the water content of the dried object is based on the system parameters of the drying container in a closed state to calculate.
[0047] Specifically, the water content M1 ...
