Drying of bee-bread is an important technological process, which determines the quality of the product produced. Drying of bee-bread is carried out in conditions that prevent the occurrence of irreversible changes in the product, which can lead to deterioration of its quality. These changes are largely associated with the processes of denaturation of proteins and inactivation of enzymes caused by heating of bee-bread during drying at temperatures above 40ºC. Analysis of literature sources has shown that bee-bread is dried mainly either by convection or vacuum drying. Sometimes these drying methods are combined with infrared heating. The disadvantage of the convection drying method is the high energy intensity of the process. The disadvantage of the vacuum method is the high cost of equipment, so it cannot be recommended for small businesses. To reduce the drying time and energy intensity of the process, it is possible to add infrared heating to the main drying methods. But to date, parameters and modes of operation of such a technological process are not defined, which makes it difficult to use it in agriculture. The article presents the results of modeling the joint use of convection and infrared methods of drying bee-bread in the device focused on small businesses. Simulation of the combined drying process was carried out in the program Comsol Multiphysics 5.4. The resulting mathematical model allows determining parameters and modes of the process of drying bee-bread without losing the quality of the product.

To improve the ecological purity of agricultural products it is necessary to look for new ways of pest control. Earlier studies show the prospects of using electroactivated solutions – anolytes for bactericidal treatment of bee colonies. The article analyzes the problem of describing main physical and chemical processes occurring during the electrochemical water activation. It is proposed to carry out modeling of electrolysis processes in Comsol software package. As a result of the necessary settings, this package is able to describe the basic physical and chemical processes and obtain solutions with a high level of coincidence with experimental data.

Analysis of the health status of bee colonies has shown that constant prevention and treatment of bees from concomitant diseases is necessary. The health of bees is directly related to their productivity. Most beekeepers use highly active chemicals to process beehives and inventory. To change this situation, it is necessary to search for new solutions for the treatment of bees. One of the ways to solve the problem is the use of environmentally friendly and harmless to bees and beekeepers electroactivated solutions obtained using diaphragm electrolyzers of water. The conducted studies of the developed model of a diaphragm electrolyzer using the Comsol program allowed us to obtain information about the physicochemical processes occurring in it over time. Comparison of simulation results and experimental data showed their good coincidence. Studies on the treatment of bee colonies in the apiary with electroactivated solutions can halve the use of chemicals and reduce the likelihood of drugs getting into bee products.
