Development and justification of the parameters of a destemmer for dried grapes

The article discusses the design features of a destemmer for dried grapes in order to remove the ridges and stalks from them. A series of experiments were carried out on the destemmer design developed by the author, as a result of which the patterns of interaction of various working bodies with dried grapes were established. The most effective operating modes of the destemmer and the optimal parameters of the working parts have been established. Based on the results of a serial industrial test, it was established that this design has a high degree of crushing of bunches and cleaning of dried grapes.
