    Analysis of the technological process of hop drying in belt dryers

  • Original language description

    Current problems of the present technology of hop growing include complex innovation in the drying process in existing belt dryers. The drying parameters were monitored by means of continuously recording data- loggers and a laboratory analysis of the samples (hop moisture, alpha bitter acids, hop storage index). The drying process revealed that the hops are virtually dry (10±2.0% of moisture content) already at the end of the second belt, or possibly at the beginning of the third belt. The hop drying proved that hops are considerably over-dried (moisture content of 4 to 8 %) and are subsequently adjusted through conditioning to the final moisture content of 8-10%. Over-drying leads to a substantial shattering of hop cones, a factor which renders the manipulation with hops for further processing more difficult, leading to larger losses in the lupulin content.
