Work

At the present stage of development of drying processes in Ukraine and the world there is an urgent need to create and develop highly efficient drying equipment that would ensure minimal energy consumption and high-quality material. Drying processes in the world consume 10-12% of all energy. In Ukraine, according to our estimates, these processes consume 25% of all energy, and in the agro-industrial complex alone - 15%. This evaporates up to 5 million tons of moisture, which belongs to the greenhouse gases, into the environment. The world has begun to use the condensation method of dehydration, which uses a heat pump. Energy consumption for moisture evaporation is 3… 4 times lower than energy consumption in existing dryers. Due to the use of low-temperature energy of the spent heat carrier in the heat pump. And in the dryer when using this method, the partial pressure is reduced, which intensifies the process of removing moisture from the material. But for the proper use of this method, additional research is needed. The purpose of the work is to increase heat and mass transfer during dehydration of thermolabile colloidal capillary-porous materials during drying of functional plant raw materials with preservation of biologically active substances of initial components in innovative heat-pump dryers. The main tasks of the research project: on the basis of theoretical and experimental researches to substantiate increase of energy efficiency of heat and mass transfer processes during drying of thermolabile functional vegetable raw materials with preservation of biologically active substances of initial components. With the development of energy-efficient dehydration modes and modernization of heat pump dryers.
