| Abstract Hops (Hurroulus kipulus L.) are basically used in beer production to impart bitterness, aroma, flavour and for microbial stability. The substances in the hop that possess these characteristics are mainly alpha-acid and hop oils. Alpha-acid is an important quality index which most buyers and farmers in the hop industry concentrate on. Several studies in drying of hops have shown that the use of high drying air temperature and constant air speed offer opportunities to save energy and yield welldried hop cones. However, several other factors also affect the drying and the quality of hop cones. The methodology involved the drying of some varieties of hops in the three farms, Farm 1, 2 and 3, determining the relative humidity of the drying air, the... |
