Walnuts are currently a unique product, the components of which are used in the food industry, the production of medical and cosmetic products, the production of building materials, as an energy product and in other areas of activity. Ukraine is one of the leading producers of walnuts, but most of them are offered in the shell. The maximum economic efficiency of walnut processing technology is achieved through the use of a full cycle of processing and the use of all components: pericarp, kernels, shells, membranes. Therefore, the development of an energy-efficient line for a full cycle of walnut processing is currently very relevant for this promising branch of agriculture.  Analysis of recent studies and publications shows that the attention of researchers and practitioners in most cases is directed to solving individual problems that arise before them, that is, individual technological processes and operations have been studied. Namely, the complete processing of sins ensures the maximum profit from their cultivation. In this work, the authors set a goal to develop a technology for processing walnuts that would provide the most complete cycle of their processing, which will provide, accordingly, the maximum profit from its implementation. The technology of complete processing of walnuts involves the use of a significant number of different machines that use different types of energy. For more efficient use of energy, it is recommended to use measures and means that intensify technological processes. In particular, an effective means of intensifying technological processes is the vibration effect on the processed material. This is especially true for the drying operation, because the implementation of this operation requires almost half of all the energy consumed in the technology. The technology also involves the use of non-traditional energy sources.
