A method for improving the efficiency of screening pumpkins and courgettes seed mixtures on the sieves

Abstract

In the work analyzed the prospects for improving the sieving pumpkins and courgettes seed mixtures. It has been established that existing methods lack the performance and quality of cleaning and separation, high intensity and energy intensity. Most common machines are air sorting tables and air classifiers, which due to the above listed shortcomings cannot meet modern production. The existing sieves vibroseparators have potential in terms of performance and power consumption. But serial sieves with round or elongatedholed screens may not ensure the necessary quality and performance sifting seed mixtures, courgettes and pumpkins. Therefore, the work aims to find solutions to this urgent question. Analysis of existing ways to improve screening of granular environment found that usage of intensifiers and activators on vibrosieves there are promising and effective. Experience of using vibrosieves with rectangular volume activators for intensification of sifting grain mixes corn, which is confirmed by the theoretical and experimental research, predicts a similar increase in the effectiveness of the screening when the separation of various seeds flat form. Conducted experimental research made it possible to identify the dimensional characteristics of seed mixtures, pumpkins and courgettes. Installed variation curves of the main dimensions of seed: length, thickness and width, which made it possible to determine their ranges of variation. Given the ranges obtained defined benchmarks sieves with volume activators to seed mixtures, pumpkins and courgettes. Further theoretical and experimental research will test the solution this way and optimize the structural and kinematical parameters designed sieves for pumpkin seeds and courgettes.
