Abstrakt
Cleaning potato tubers from soil and plant residues after their digging from the soil is
a topical problem in the industrial production of potatoes. Taking into account the fact that the
cleaning spirals are positioned with overlapping and rotate in the same sense, the potato tuber that
has landed on the surface of the spiral separator in the trough between two adjacent spirals will
perform translational motion towards the output ends of the spirals. As a result of solving the said
system of equations, the graphical relations between the values of the normal reactions and
friction forces generated during the translation of the potato tuber along the mentioned spirals, on
the one hand, and the design and kinematic parameters, on the other hand, based on the
requirement of not damaging tubers when performing the said work process of transportation and
cleaning, have been obtained. The limitations for the normal reactions and friction forces at the
points of contact between the tuber and the surface of the cleaning spiral are set in accordance
with the requirement that they do not exceed the force of scraping (damaging) the tuber’s external
surface permissible for potato tubers. That has provided an opportunity to obtain the rational
values of the design and kinematic parameters of the separator’s operating spirals, in particular,
the value of the angular velocity of the rotating cleaning spirals as well as their radius and helix
lead.
