Hop drying in belt dryer using cooling chambers

Popis výsledku v původním jazyce

When drying hop cones, sufficient drying of strigs is the bottleneck. Bracts are then dried up to such a level which makes pressing the hops impossible. That is the reason why hops are conditioned after over-drying to reach an optimum moisture content of 10 to 12 %. This process does not benefit hops, therefore we suggested to substitute the conditioning chamber for two cooling chambers, in which the moisture of bracts and strigs can be equilibrated. This equilibrium is essential for baling. The advantage of this drying method is energy saving and improvement in the quality of the hop product. On the basis of the patented design and a utility model, the apparatus was assembled at the belt dryer PCHB 750 of Agrospol Velká Bystřice Ltd. Comparing the operation with conditioning and the option of the cooling chambers, the gas savings amounted to 2,356 CZK.t-1 of dry hops and the electricity savings amounted to 831 CZK.t-1 of dry hops. Assuming the reduction of the harvest period by approximately 39 %, t
