The article deals with the properties of the DMA apparatus which is used in laboratories to measure the density of sweet wort. Though the measurements require more time than operations performed with conventional instruments, they on the other hand - provide very reliable and accurate information. Besides, all measurements are carried out automatically without any assistance by qualified workers and data need not be calculated from the mass enclosed in a density bottle. The DMA apparatus is rather expensive and should be consequently used mainly in central laboratories.(In Czech, English summary only)

In distilleries producing grain alcohol traditional kilned malt, used to split up starch-containing raw materials, is now frequently replaced with microbial enzymatic preparations. Beside α-amylase very important is also glucoamylase, because it can split-up even α-1,6 glucosidous bonds of limit dextrines and increases thus the proportion of fermentable sugars. Substrates containing stillage are used for submerged cultivation of Aspergillus batatoe and Endomycopsis bispora the sequence of further operations being as follows. The mixture of non-filtrated media used to cultivate the two mentioned microorganisms is added to starch-containing...
Drying bakery yeast in fluidized bed.Peer-reviewed article
Z. BERAN
Kvasny Prum. 1980; 26(5): 109-114 | DOI: 10.18832/kp1980018
The article deals with the results of laboratory yeast drying experiments, with hydrodynamics and specific properties of fluidized bed, as well as with kinetic and thermal conditions of drying. The author analyses the influence of individual factors on drying process and outlines method to be applied to obtain a correct drying rate curve. Continuous and semi-continuous drying processes are compared and evaluated. A pilot plant of 100 kg/hr dry yeast capacity and achieved results are described.(In Czech, English summary only)
