The given review of hygrothermal processes in the processing of grain crops, their features is presented from the standpoint of nanotechnology. It is shown that for the developed nanotechnologies in the production of agricultural products, it is necessary to apply non-traditional methods of process research, which is the method of similarity of the functioning of technical systems (SFTS). This method will allow for the processes of humidification, drying, wet-heat treatment in vacuum conditions to obtain generalized similarity criteria, determine their numerical values and obtain generalized criterion dependences of the intensity of the processes under consideration on the processing parameters. The implementation of the method will allow us to quantitatively describe the processes of hygrothermal grain processing in vacuum conditions, assign processing parameters and manage them. Mathematical models of hygrothermal processes have been developed based on the method of similarity of the functioning of technical systems depending on the parameters of the medium and the structure of capillary-porous grain shells.
