Outlook for new filtration techniques in brewing application of cross-flow microfiltration for rough beer clarification

Among the numerous applications of cross-flow microfiltration (CFMF) in the food processing industry, beer micro-filtration represents a wide potential market and an interesting technological challenge. CFMF and its potential applications in brewing are presented here. The purpose of this paper is to show that rough beer CFMF is a technical alternative to the conventional dead-end filtration with filter aids (diatomaceous earth).

Begerow Filtration Seminar

Following on the positive reaction to the 1996 Seminar, and in view of the many questions and problem areas arising since that time, E. Begerow GmbH & Co. company of Langenlonsheim/Germany organised another Filtration Seminar in 1998.

Fully automatic kieselguhr dosage plant

Though modern filtration techniques are used in beer filtration, the filter aids required are still prepared to a very large extent manually.

Silica sols as clarifying and stabilising agents in beer productionProblems - Mode of action - Tests for optimising the application

This contribution deals with structure, possible modifications and mode of action of silica sols used in unfiltered beer to improve filterability and raise colloidal stability. Test methods applicable to commercial situations are presented.

Vessel filter systems for precoat filtration

Kieselguhr filtration is state-of-the-art nowadays for prefiltration of beer. No other filtration method comes even close in terms of performance and economics. Commercially available systems are mature and proven. Nonetheless, users still have questions about optimal apparatus and processes suited to their specific plant conditions. Familiarity with design and process characteristics simplifies selection for a specific plant situation.

Economics of fine and sterile filtration in medium-sized German breweries

This paper contains a report on fine and sterile filtration immediately ahead of filling in three medium-sized German breweries.

Test results obtained with PFS-filter in fine filtration of beer

For many breweries, a yeast-free filtrate in the bright beer tank is a minimum requirement in terms of microbiology. In order to achieve this, final filtration is required in order to assuredly separate out particles and yeasts. The most frequently used equipment is sheet filtration. Despite a number of new developments in recent times, sheet filtration involves certain disadvantages. This paper describes the results of a long duration test with a new system for final filtration.

Treatment of kieselguhr slurry from beer filtrationEnabling utilisation for agricultural purposes

Accounting for about 50% of total waste of breweries, kieselguhr slurry constitutes a big problem. This paper describes possibilities for utilisation in agriculture.

Bypass membrane filtration (BM-system) - improvement in detection of trace elements after filtration

The following article describes a continuous sampling system for detection of trace contaminants in beer. This has been developed for process use in close co-operation with the Chair of Technology of Brewing I, the Chair of Fluid Mechanics and Process Automation and Haller Löwenbräu/Wildbachquelle SHA.

Automatic membrane filter plant for cold sterile beer filtration

Increasing interest is being focused on cold sterile beer filtration as an alternative to flash pasteurisation. The automatic beer filtration plant described here combines a compact arrangement with a high degree of automation and operator comfort.

A proposal for a filterability and stability check in unfiltered storage beer

A filtration check aimed at establishing the causes of problems encountered in beer filterability is presented. These checks focus on pH measurement, haze differentiation, alcohol-cooling test, membrane filterability, detection of high molecular weight a- and b-glucan concentration. This article proposes a course of action and gives technological recommendations for optimisation.
