Barm beer can be recovered from excess yeast by means of suitable recovery systems. These include, in the main, centrifuge processes (decanters and disc centrifuges) and membrane separation techniques (cross-flow and vibration microfiltration) ([1], [2]). A multiplicity of parameters are used in order to evaluate whether barm beer can be returned to the brewing process or, indeed, if a recovery system is suitable in the first place. This contribution provides a general overview.

Even today conventional test methods still take three to five days. For this the quick detection method FastScan® only recently developed by the Scanbec GmbH (limited liability Company) in Halle, Germany, poses a real alternative. Already after two hours (after precultivation of 24 hrs) a reliable result can be achieved by this method.

The Combined Stabilisation System (CSS) is designed to improve the physical stability of beer through the adsorption of both haze forming proteins and polyphenols by the polysaccharide agarose. In 2005, Lion Nathan commissioned the first large scale CSS unit in the Tooheys Brewery, Sydney. The subsequent trials proved that the CSS has the ability to improve the physical stability of beer within the operational requirements of a large commercial brewery. Physical stabilisation by the CSS appears to occur by the selective adsorption of haze forming polyphenols, in particular prodelphinidin B3, and haze sensitive proteins whilst maintaining foam quality.

Extensive discussions about kieselguhr-free filtration techniques during the past EBC-Congress in Prague showed, that membrane filtration systems became a serious competitor to kieselguhr filtration systems. In 2004, NORIT has developed a new Beer Membrane Filter (BMF), Type BMF-200. An operating expense analysis of this new beer membrane filter type was done at Oettinger Brewery in Oettingen/Germany, where this new filter type is in use for over eight months now.
The crossflow-microfiltration plant in the Oettinger Brewery was developed as a single-step beer clarification system without a separation step (see Fig. 1). Unfiltered beer is delivered to the cylindro-conical unfiltered beer buffer tank, while blending PVPP and Hydrogel.e. ...

In recent years, kieselguhr filters had to comply with more stringent requirements both in terms of better performance and also in terms of filtrate quality. The Innopro Getra Eco kieselguhr candle filter, a new development from KHS, has everything it takes to fully meet both criteria.

In this paper, the Innopro Getra Eco filter will be described in more detail, taking a filter plant as an example that has been in operation, without any complaints whatsoever, for several years in Obolon Brewery in Kiev/Ukraine.
As of January 2002, the Innopro Getra Eco has filtered more than 10 million hl of beer at Obolon. The brewery wanting to produce a bright beer was more than satisfied with the result. Average haze is below 0.4 EBC (Sigrist 90°), a value of far below 0. ...

On the occasion of its 20th anniversary, Gernep GmbH will provide a comprehensive overview of its product line. Labelling machines for wet glue labelling, a combination of wet glue and self-adhesive labelling as well as wrap-around labelling will be exhibited. The "Labetta" series label-ling machines offer almost unlimited decoration possibilities due to flexible arrangement features. Retrofitting to suit new bottle and label formats is unproblematic and cost-effective thanks to the rotating guide element divided into segments. Individual options such as L or U-shaped neck applications and band-shaped labels can be set up easily and combined with standard body, shoulder and back labels without the slightest problem.

Filtrox, one of the leading specialists for equipment and filter sheets for beverage filtration, with more than 1500 installed filter lines worldwide, presents itself at drinktec under the motto "We care", thus fully responding to the trend of our times where, due to limited funds for new investments, existing plants continue in operation while being optimised and modernised. ..

Alfa Laval will emphasise the importance of kieselguhr-free beer filtration based on the cross-flow process. Apart from cross-flow filtration, the company will also present sterile and trap filtration systems as well as technologies for producing beer with a low alcoholic content and a system for beer recovery from excess yeast. Both systems use membrane technology.
The new Foodec series decanter centrifuges have been specifically developed for the brewing and beverage industry, particularly for recovery of wort and beer, as well as for dewatering spent beer grains and brandhefe. In wine production, they are used for must clarification and wine recovery from yeast sediments. Yield, quality and protection from external influences (oxidation) are important factors in these processes. ...

Does Big, Bigger, Biggest mean Good, Better, Best? Perhaps. And only if you are well-positioned for superior growth and profitability, says InBev. Globalization is a big word with a fittingly big reach and big implications for the global brewing industry. Prepare yourself for a flurry of activity and a deluge of Newspeak as brewers try to become "the bestest" - no less will do - in this round of market consolidation.

It is a well-worn cliché to observe that we live in an age of globalization. Globalization is the integration of capital, technology, and information across national borders, in a way that is creating a single global market and, to some degree, a global village. ...

The article tries to connect theoretical basics and new findings in producing and using of silica gel as beer stabilisation medium. Against the background of the still existing need for research possible ways of research and development are shown that can serve as platform for both interested manufacturers and users for further discussion. Silica gel is a synthetic product based on silica in powder form with different water content. With a D50-value of approx. 25 µm and a D90-value of approx. 100 µm regarding its particle size distribution silica gel is a fine to medium fine product (D50-value = mesh size of a sieve in µm for 50 % transit of the material; D90-value = mesh size of a sieve in µm for 90 % transit of the material). In both cases water glass is the determining main component. .

Disposal of the usual kieselguhr filter aid is turning out to be increasingly problematic against a background of new legal regulations for feedstuffs production and waste recovery. Altenberg Brewery has been using a new technology based on regeneration since 2004 the BeFiS (Best Filtration System). The partners who developed the process have drawn up implementation and validation documentation as well as an environmental balance and a commercial evaluation. Part 1 of the report focuses on process equipment.

Precoat filtration with kiesel- guhr represents the standard procedure in beer filtration. The aids are used just once and are discarded after use. About 90,000 tons of kieselguhr sludge arises in German breweries every year. ...
