Kvasny Prum. 1957; 3(3): 49-51 | DOI: 10.18832/kp1957010 
The article contains principal information about the new construction of malt kiln with two fences according to M. Růžička, using the natural draught. It is supplied with indirect combined heating by means of flue gas and low pressure steam. Instead of the commonly used fire place there is Roučka9s vertical boiler and air stove supplied with pile shaped air heater with large heating surface offering minimal resistance to the flow air. The heat supplied to water is utilized for the malt kiln and the air under the grade. The results of commercial tests as well as the experinces in the factories have shown, that the new type of malt kiln meets all technological...
The losses during the beer production.Peer-reviewed article
V. BÍLEK
Kvasny Prum. 1957; 3(3): 52-54 | DOI: 10.18832/kp1957011
The author discusses the influence causing indistinct results in the difference between the amount of extract determined by means of analysis of malt and the amount of extract gained in the brewhouse, as calculated from the volume and concentration of produced wort. The correct determination of the losses "between the laboratory and brewhouse" is influenced, as far as the consumption of malt is concerned, by the sampling of malt, by the permitted swing in the determination of extract, by the method of calculation of extract, as well as the different methods of its determination made in the laboratory and in the factory. Special attention...
The value of sewage waters from breweries.Peer-reviewed article
V. POSPÍŠIL
Kvasny Prum. 1957; 3(3): 54-56 | DOI: 10.18832/kp1957012
The author has studied the qualitative and quantitative losses of extractive matter in the sewage water of a brewery with the capacity of 300 000 hl beer per year. He draws special attention to these points: 1. The unavoidable pollution of sewage waters caused by the losses of extract, can be reduced, but not quite avoided. 2. The losses in the running. 3. The losses in the spent hops. 4. The losses of dry matter in the trub, which were hitherto not used. 5. The losses of yeast passing into sewage waters.(In Czech, English summary only)
The yeast return in the distilleries.Peer-reviewed article
J. BÁRTA, M. ROSA
Kvasny Prum. 1957; 3(3): 58-60 | DOI: 10.18832/kp1957013
The authors evaluated critically the centrifugal separation of yeast during the production of spirit according to Boinot. Basing on their own experinces the authors suggest an arrangement of technological processes with centrifuging in the final stage of fermentation. The causes of failing fermentation are described. For the case of strong contamination combined with agglutination the authors suggest to use double separation after foregoing liberation of the groups by means of acidification to pH 3,5. One of the causes of decay of yeast in acid medium, due to unsuitable pH value during the mean fermentation process is described.(In Czech, English...
A new raffination apparatus.Peer-reviewed article
B. MELICHAR
Kvasny Prum. 1957; 3(3): 60-62 | DOI: 10.18832/kp1957014
The author refers the results of final commercial tests made with the Gregor9s raffination device (ČSP No. 83086). A scheme of the device as well as the description of its work are added. The results of tests are arranged in 3 tables. The author concludes, that the high effect in the production of fine spirit can be attained only by inducing the diluting water on the highest bottom of the separator.(In Czech, English summary only)
