Marksa, Novosibirsk, 630073, Russian Federation Abstract In article presents the process of numerical calculating the time of potato cleaning from the outer peel for three models of MOK machines. The basis for calculations is the “calculated diameter” tuber, considered as an orb, whose diameter is equal to the average diameter of all the tubers in the serving. Formulas that make up the calculation process are presented in tabular form and each table forms an algorithm for solving four tasks: the choice of initial data, the calculation of the number of tubers in the chamber and the number of tooth contact of the tuber with the abrasive surfaces of the chambers, calculating the cutoff forces of the outer layer, rotational speed of the bowl and the power of the process. These factors ultimately determine the cleaning time of tubers, the productivity of the machine and the power of the cleaning process. Comparison of the results of calculations by machine standard sizes allowed to establish general regularities, necessary for the design of their structures Keywords potato brusher machine, abrasive camera, cleaning time, diameter of a tuber, tooth contact, centrifugal force, power, productivity.
