Study of properties of malt kilned on a one-floor laboratory kiln.

Abstract

The study deals with the problem of homogeneity of the malt produced on a one-floor high-capacity kiln. The experiments carried out on a laboratory one-floor kiln proved that there exist a statisticly significant influence of the kilning variants and the position of the malt layer on the monitored quality parameters. This effect has become evident mainly in case of lock of air and its non-uniform permeation through the kilned malt. It was proved that the course of predrying and intensity of malt kilning. It was confirmed that the technology of kilning which is favourable to the conservation of the b-glucanase activity is not proper for the reduction of content of the precursors of dimethylsulfide in malt.The study deals with the problem of homogeneity of the malt produced on a one-floor high-capacity kiln.
