One of the factors of the destruction of the bonds of grain with the hit when threshing the bread mass with a shock-vibrating threshing device is the impact of the roll edge on the bread mass. The very word "blow" without a clarifying supplement can have various meanings associated with various branches of science. Its meaning expresses the idea of a sudden fact; although in different branches of knowledge it is not identified. We have considered only certain aspects of the physical impact associated with the impact of the working organs of machines and the material being processed. The article presents a study of the impact pulse of a threshing device on bread mass. To reveal the essence of phenomena when a working organ is impacted by grain, a graph analytical method is used. Dependences allowing determining the impact pulse of the milk roll edge on the bread mass, geometric and kinematic parameters of the threshing device are obtained, and also can be used to determine the energy costs
