Abstract

The article summarizes the results of a two-year research focused on separating impurities in hop picking line by means of inclined belt conveyors. Researchers designed a new version of inclined belt conveyors which were installed in one segment of a parallel hop picking line. In the other segment the current inclined belt conveyors remained. Regarding the product quality, better results were obtained with new inclined belt conveyors where the average content of impurities at the output was 7.73%, contrary to the treatment with current conveyors where the content of impurities was 12.03%. The current inclined belt conveyors had 4.8 times higher losses of hops than the new ones. The economic assessment clearly proves the use of new inclined belt conveyors to be more effective, as the return of the costs for the exchange of six inclined belt conveyors in a picking line makes only 3.13 years at a comparable or even better quality of separation.
