V. HORYNA
Kvasny Prum. 1979; 25(11): 233-236 | DOI: 10.18832/kp1979035 
The first part of the article deals with history of production of machines and equipment for brewing industry which started in the ZVÚ Works at Hradec Králové many years ago. Then the author spacifies the present manufacturing program paying special attention to equipment for brewhouses. He describles all avaible types, i. e. for conventional brewhouses, gravity and one-storey ones. Under the designation of equipment are understood all installations and machinery required to prepare wort,i.e. malt crushers, cooling systems, water supply systems etc. In their desing and constuction prevail trends to automated,...

Kvasny Prum. 1979; 25(11): 241-245 | DOI: 10.18832/kp1979036
In the presented study the authors followed the inhibition of thr amylase activity using riboflavin and the chelating agent. Conditions under which the a-amylase activiti is practically completely inhibited, while the β-amylase activity remains untouched, were also studied. A rapid and simple method of determination of α- and β-amylase activity in the malt was established. The metod is based on the inaktivation of α-amylase with riboflavin or Chelaton 3 solution (EDTA), is precise, rapid, and suitable for the determination of α- and β-amylase activity in the germinating barley,performed in control brewery laboratories....
New Criteria for Evaluating the Malt.Peer-reviewed article
A. DOLEŽALOVÁ, M. NENTWICHOVÁ
Kvasny Prum. 1979; 25(11): 246-248 | DOI: 10.18832/kp1979037
The article deals with new methods which are to be introduced and applied and applied to evaluate the properties of malt. They include determination of malt extracts, colour, viskosity and attenuation degre of wort. New methods meet the requirements of brewing industry,will unify evaluating criteria and ensure reproducibility of results.(In Czech, English summary only)
Optimizing the Process of Manufacturing Fodder Yeast from Ethanol.Peer-reviewed article
F. MADRON, K. EDERER, F. ŠTROS
Kvasny Prum. 1979; 25(11): 249-257 | DOI: 10.18832/kp1979038
The authors outline ways how to optimize conditions required for manufacturing fodder yeast from ethanol. They have worked out a mathematical model of a plant producing yearly 25000 tons of fodder yeast and analyze the effects of achieved yields upon manufacturing costs. Optimum concentration values of biologic substance for various of isolation line have been determined, too.(In Czech, English summary only)
Malt Processing Equipment Manufactured by ZVÚ Works at Hradec Králové, Its Present Range and Development Plans.Peer-reviewed article
Z. LUKÁŠEK
Kvasny Prum. 1979; 25(11): 257-260 | DOI: 10.18832/kp1979039
The manufacturing program of ZVÚ N. C. Works at Hradec Králové includes several types of malt mills and covers practically all requirements of brewing industry. The Works offer both four-roll and six-roll malt mills Which can be combined with malt conditioning plants. Two-roll wet-crushing mills can grind also unmalted barley.(In Czech, English summary only)
