ArticleIn order to increase substantially the quality of the potato heap separation, it is
necessary to carry out the theoretical substantiation of the spiral separator’s parameters with
regard to the impact interaction between the product and the tools of the un
it under the condition
of not damaging the tubers. An equivalent schematic model of the impact interaction between a
potato tuber and the surface of the rebounding conveyor has been devised. Taking into account
the coefficient of restitution of the tuber’s
velocity in case of an impact, new analytical
expressions have been obtained for determining the magnitude and direction of the potato tuber’s
velocity after the impact. They provided the basis for applying the principle of momentum at
impact and obtainin
g the analytical expressions that allow determining the impact impulse and
impact force at the impact of the tuber on the surface of the rebounding conveyor and, eventually,
the dynamic constraints on the permitted velocity of the tuber prior to the impact
interaction under
the condition of not damaging it. A new analytical mathematical model of the impact interaction
of the potato tuber during the potato heap separation has been developed. On the basis of the
obtained theoretical results, studies have been
carried out
on the rational kinematical parameters
