The paper considers a promising and effective screen-type potato sorting, included in the mechanized complex for potato post-harvest processing and storage. The main technological equipment of potato sorting stations is a sorting device that separates potato tubers into size fractions. The paper emphasizes the relevance of developing effective methods for designing and calculating the parameters of this type sorting devices. (Research purpose) To upgrade the sizing machine drive by modifying the sieve movement patterns for improving its operation efficiency. (Materials and methods) The present research exploits the critical analysis methods of the theory of mechanisms and machines in order to design the optimal design of a sieve-type potato sorting drive. It is proposed to use a two–stage drive mechanism. To compare the movement patterns of the screen sieves, the efficiency coefficient has been calculated for two drive options. (Results and discussion) It is obtained that the sieve efficiency coefficient is 0.30-1.65 for a screen type sorting device with a two–stage drive mechanism, and equals 0.27-1.35 for a screen type sorting device with a crank drive mechanism. (Conclusions) It is recommended to use a lower drive shaft speed of – 13.12-14.76 radians per second, at the crank angular velocity of 20 radians per second in the crank drive mechanism. The sieve mounting angles are to be set within 6-8 degrees.
