Improving The Calibration Quality Of A Vibrating Sieve-Type Potato Sorting Machine By Optimizing Its Technological Parameters

Аннотация

A promising and efficient vibrating sieve-type potato sorting machine, which is a structural component of a mechanized complex for post-harvest processing and storage of potatoes, has been studied. The relevance of developing effective methods for designing and calculating sorting equipment that classifies potato tubers into fractions by size is emphasized. As a result of theoretical research aimed at designing an optimal configuration of a vibrating sieve sorting machine, a highly efficient device was developed. According to the experimental results, the highest calibration accuracy reaches 94%. This level of performance is achieved under the following operating conditions: product feed rate – 18 tons/hour, sieve vibration amplitude – A = 30 mm, vibration motor speed – 300 rpm, inclination angle of the calibrating surface – β = 7°, crank inclination angle – ɛ = -6°, and spring stiffness of the vibration mechanism – k = 13 N/mm.
