IMPROVING THE EFFICIENCY OF TECHNOLOGICAL EQUIPMENT FOR PEELING CEREAL CROPS

Abstract

One of the means of increasing the efficiency of the process equipment may be non-standard use of known technical elements. Modern peeling machines operate using compression and shear, single or multiple impact, continuous abrasion of the casings. When implementing any of these methods, a high degree of peeling with maximum preservation of the integrity of the core remains the main requirement of the technological process. Despite this, the finished product always contains crushed particles. An analysis of literary sources showed that roller machines with rubberized rollers are the most widely used. However, their working coating is short-lived and frequent adjustment of the working gap is required. This leads to the need for periodic repair impacts, which is associated with significant costs of working time. Increasing the convenience and reducing the time spent on maintenance is possible by simplifying the design of the attachment point of the rubber roll to the hub and is an urgent task. The review of patent sources identified the main directions for solving this problem. However, all the considered designs do not have the required level of efficiency. Therefore, the author of the article proposed an original constructive solution to this problem. In the proposed design of the shelling machine roll, rubber O-rings are used as elements connecting and transmitting rotation from the hub to the rubberized roll. The performed calculations prove that the specified ring will ensure tight contact between the hub and the bandage. Thus, annular elastomer seals can be used not only for their intended purpose, but also as power elements for fixed coupling of parts, expanding their scope.
