The Diploma presents the composition of a Vacuum dryer and the course of research in the field of Vacuum drying. Vacuum drying is used in various branches of industry mainly due to lower process temperatures, shorter drying times and lower electricity consumption. As the pressure decreases, the evaporation temperature of the water decreases, leading to lower drying temperatures. This creates more suitable drying conditions for more temperature-sensitive materials. In the research, we will observe the influence of the electric power of radiators and air flows on the temperatures in the test clothes at different pressures. The introductory part presents the theoretical foundations, which relate to the physical properties of water, the diffusion of water vapor into the environment and heat transfer through radiation. The methodology of the work presents the composition of the measuring line required for the performed research, the measuring system used for data acquisition and the course of the performed experiments. In the last part of the thesis, the results of experiments, their analysis and guidelines for further research are given.
