Yeast management in a brewery comprises the processes of yeast culturing in the laboratory, yeast propagation, transfer to the plant, and working with cropped yeast. Working with cropped yeast encompasses the time of yeast harvest, yeast handling proper after harvesting, storage and re-pitching. However, yeast propagation is the core of a yeast management system. In this article, the authors report on ten years’ experience in commercial operations with assimilation technology.

Winter barley has a higher yield and is therefore of economical interest for farmers and the malt industry. However, in Germany only an area of approximately 30 000 ha exists for the cultivation of winter malting barley. One reason for this is the malting quality of winter barley which is

Observations of the classical system in commercial operations at the usual starting temperatures of about 71°C demonstrate that quite severe pulsations sometimes occur during the heating phase. This leads to thermal damage in wort and to mechanical damage in equipment. Possible solutions to eliminate pulsation hitherto include

Development of suitable recovery plants in recent years was mainly influenced by stricter quality standards implemented by brewers. In this paper, the authors present the pros and cons of various separation techniques and describe the underlying principles. Determination of yield has proven itself in breweries as an indication of economical viability.

Reverse osmosis plants have become widespread for water treatment in the beverage industry, due to their improved technical performance, flexibility and operation. But high waste water costs can be reduced. This article analyses operating costs – also compared to capital costs – and describes a process that has been implemented and is suitable for operating reverse osmosis with approximately the same yield as full demineralisation or softening.

Breweries are seeing an increasing amount of pressure put on prices and have to take a critical look at their costs. This is difficult because marketing costs are increasing, it appears to be almost impossible to reduce the process costs and environmental regulations are becoming increasingly stricter. However, the end user wishes to enjoy an excellent beer for a reasonable price and, for this reason, breweries must find clever cost savings. Haffmans BV in Venlo/NL has developed three concepts for reducing costs through the use of CO2 recovery technology. The approach presented here has a cost savings potential of up to 60%.

Ion exchange plants remain state-of-the-art in breweries and soft drinks plants, despite increasing competition from membrane technology. They have the advantage of fast response times and can be easily automated. The following paper describes the most appropriate functional principle for each operation so as to arrive at a customised solution.

Lambrini and Red Square are typical representatives of so-called ready to drink beverages. In Germany however, these beverage types had a clear drop in sales due to a compulsory tax, but in the rest of Europe, the fruity sweet, alcoholic mixtures (on average approximately 5% vol. alcohol, thus as much as beer) made of lemonade, spirits and several ingredients, are very popular.

The forerunner and trigger for this wave of "premixes", "PPS" (pre-packed spirits) or "RTD" (ready to drink) was England exactly ten years ago - and more specifically: Halewood Ltd. from Liverpool. The two most important brands are "Lambrini" and "Red Square" which are being sold worldwide in 31 countries.Thiedig + Co., Berlin. with an assured measuring quality, robustness and simplicity of use. ...

This article points out the new Drinking water ordinance (TrinkW 2001) to the beverage industry operations and substantiates checking their own water utilisation sites. The procedures in terms of cleaning, disinfecting and purification of the systems comply with different requirements. Horst Grund sums up both benefits and suitability and presents the new IMECA®-system.

Quality always stands in the foreground.
The media daily suggest products with convenience and quality to the consumer using advertising slogans like "from deep wells" or "highest purity". Quality is a cachet and status symbol with which good money can be earned. Each product is subject to a control and fall-back system. bear a certain risk to the biological status. ...
