2 The Pall World Pall Corporation is a world leader in the design, production and supply of filters, membranes and systems for the filtration and separation of liquids and gases. With an annual turnover of more than a billion dollars, we are able to handle major projects on a safe and sustainable platform. Industry drivers for DE free filtration Public and legislative debate surrounding the health and safety classification of DE Diatomaceous Earth (DE) is the most commonly used and approved filter material for beer clarification. It offers excellent filtration characteristics whilst maintaining the desired taste and body of the product, however the sustainability of DE filtration has recently been called into question for the following reasons: Handling and storage considerations for a classified substance Inflexibility with regard to 24/7 operation Potential increased disposal costs On going requirements to reduce operational costs

3 PROFI built on partnership PROFI technology is a co-operation between Pall food and Beverage and GEA Westfalia Separator Food Tech GmbH. It is the engineered result of significant R&D investment built on the extensive and unique brewing experience of the two companies, combined in a high performance centrifuge with a crossflow dead-end membrane system. PROFI technology offers a smart solution to the demands of the brewing industry offering complete DE free clarification with direct value to the brewery: Constant high beer quality Maximum yield, lowering operating costs No filter aid handling - No purchasing of consumable filter aid - Retentate-free process through emptying the modules with CO2 in the direction of flow - No pre and post run required, hence no time in blending and storage losses - No health and safety risk management of filter aid - Reduced waste disposal costs - No mixed beers, simple change engineering - Due to minimized shear effects on the product, maintaining yeast integrity - Turbidity better than DE - Yeast free filtrate and sharp reduction in beer spoiling bacteria - Negligible oxygen from process start up Continuous operation - Smaller system sizing required - Reduced media consumption - High flexibility for brand change - Reduced BBT volume required - Permanent system availability Solution for beer filtration Unfiltered beer Clarified beer Separation of solids - combination of high efficiency centrifuge and crossflow membrane plant Chilled beer Filtered beer

4 The unique impact of the centrifuge PROFI technology employs a GEA Westfalia PROFI centrifuge. This centrifuge has a hydrohermetic feed system that provides gentle separation of the majority of the yeast cells from the product. The centrifugal element of the PROFI system benefits the brewery by providing: Low shearing effects - Colloid in the feed remain undamaged - More efficient clarification - High dry solids separation, maximizing yield - Better viability of yeast cells Simultaneous stabilization is possible by the addition of stabilizing agents that can be removed by the centrifuge Crossflow dead end the lowest velocity crossflow system The prepared product passes from the centrifuge to the PROFI membrane system. The basis for this system is a highly engineered membrane module insert covering the hollow fibre membranes. The patented module design includes: Potting in stainless steel housings for 80 C sanitization and 10 bar pressure resistance De-coupled polymer modular insert from the stainless steel housing offering unique heat stability Standard hollow fibre membrane with good beer filtration characteristics The membrane system has been engineered to operate at a very low velocity, without a retentate loop: Typical crossflow velocity m/s Offering the brewery high quality beer, as low velocity flow does not transfer energy into the product Offering the brewery minimized beer losses because the smart PROFI technology empties the system in the forward direction Offering the brewery the potential to operate 24/7 as individual modules can be isolated for automated

5 PROFI Continuous Operation PROFI technology has specifically been designed to provide a continuous operation, it is intended to be the predecessor of the continuous brewing of the future Cleaning and forward flow discharge PROFI technology also has advantages for including: The system is emptied with CO2 in the forward flow direction, optimizing the discharge process by: Standard brewery cleaners can be utilized 24/7 process operation The modular nature of the PROFI design is intended to offer breweries the reality of 24/7 production. Typical brewery quantities are used For the brewery the automated system gives benefits in terms of initial capital expenditure and on going operational costs including: Minimized energy consumption required Short process time for system discharge (10 mins) No significant increase in BOD/COD High temperature stability Minimizing beer losses (< 50 l) A reduced system requirement to take into account 24/7 continuous operation No pre and post runs required Short and simplified brand changes High Flexibility at start up and brand change Minimal oxygen uptake < 0.02 ppm Low water consumption Full automation with zero manpower operation Reducing power consumption per hectolitre Minimized water consumption per hectolitre Available sizes from Hl / Hour

6 Sustainability The PROFI design is the technology of the future providing high beer quality and microbiological safety on a sustainable platform. DE consumption is eradicated Energy low thermal consumption Water consumption < 0.15 Hl / Hl beer Energy Electrical kwh Microbiological safety Maximized availability due to the cluster technique The PROFI system can easily be integrity tested in-situ due to its cluster design and modular set-up. Individual integrity tests can be carried out cluster by cluster within one block during the continuous process. Beer quality is comparable to traditional DE and sheet filtration. Proven by independent laboratories and experts: Taste no difference reported (data available from Pall) Extract, alcohol, color, bitter units and foam show no difference Microbiological safety Colloidal stability comparable No increase of iron, manganese ions through filter aids Reducing waste Reducing chemical consumption

7 The ultimate assurance A PROFI system is an investment in cost effective clarification, sustainable technology and brewery flexibility. The figures below indicate the economical benefits that a brewery can be rewarded with in comparison to the operation of conventional DE clarification.
