The aim of the study was to investigate the effect of the press construction solution and the size of the sieve hole on the efficiency of the pressing yield and the content of solid particles on the raw juice. In this study two devices, included single and twin screw press were used. The devices were equipped with two sieves of different hole sizes. Based on the obtained results it was found that the pressing yield and consistency of apple juice depends on the type of press and the size of the holes in the used sieves. In the case of a single-screw press, the change in the size of the sieve holes had no statistically effect on the efficiency of raw juice and the yield of filtered juice. In the case of the twin-screw press a statistically significant effect of sieves size on the yield of pressing was observed.
