MODELING OF HONEY VACUUM DRYING PROCESSES

The aim of the study is to investigate the influence of conditions in a vacuum drying chamber on the evaporation rate during vacuum drying of honey. Objectives: to obtain the dependence of evaporation rate during drying on time; to calculate the maximum values of evaporation rate with a change in the heat flux, layer thickness, and residual pressure. The object of the study is the processes of vacuum drying of honey. The dynamics of changes in the relative mass of honey during vacuum drying is studied. The results of calculating the maximum values of evaporation rate during drying with a change in the heat flux, layer thickness, residual pressure, and temperature are presented. The maximum values of honey evaporation rate during vacuum drying are determined with a change in the relative heat flux, with a change in the relative layer thickness, relative pressure, and relative temperature. The dynamics of changes in evaporation rate during vacuum drying of honey with different pressures with a change in the relative pressure, with a change in the relative temperature, the dynamics of changes in evaporation rate during vacuum drying of honey with different pressures, the dynamics of changes in the relative mass of honey during vacuum drying from honey with different temperatures are described. The graphs of the change in the evaporation intensity during vacuum drying of honey have clearly defined maxima corresponding to the optimal drying time. The mass of honey steadily decreases at different rates, there are three clearly defined sections. A formula is proposed that allows the application of the developed mathematical model for assessing the effect of evaporation intensity during drying on gas-dynamic processes. Vacuum drying is an effective modern process, well-controlled, convenient for full automation of the process. This process has proven its suitability for various products, including honey. At the same time, the nutritional value of honey is preserved. The proposed mathematical models will contribute to further progress in the use of vacuum drying technologies.
