The reverse Carnot cycle was used to create an energy-efficient drying system for low temperature vacuum drying with a heat pump. The advantage of this technology is reduced contact of the raw material with atmospheric air and the prevention of destructive oxidation processes during the evaporation of moisture. Lower drying temperatures help to preserve the natural shape, colour, taste, and nutritional properties of the dried product. This technology contributes to retaining nutritional value and, thus, helps to build favourable consumer perception. To control system processes and ensure the interaction of human-machine interfaces (HMI), programmable logic controllers are used. The developed system offers automatic temperature and pressure control in the drying chamber, as well as signal transmission and operator control. The developed technology can be used in the production of specialised products enriched with essential micronutrients for the prevention and complex treatment of widespread alimentary and infectious diseases. The recipe optimisation is carried out to ensure the right content of bioactive compounds.
