PROFi Membrane System For DE-free Clarification of Beer

Changing requirements in the brewing industry have encouraged brewers to rethink their production technologies. Environmental aspects, consumer protection, water shortages, variations in raw material quality, labor costs or an increasing sort-variety are all factors influencing future decisions into new installations.

The PROFi membrane system is a modern beer clarification solution that minimizes waste, water and utility consumption while increasing brewery production efficiency. Designed for automated, continuous operation, PROFi membrane systems deliver speed and flexibility of brand changes with bright beer quality and high yield. The modular block design maximizes product security, cleaning effectiveness and utility usage.

The PROFi system combines a high performance centrifuge with a “zero retentate” crossflow membrane filter unit to provide efficient, DE-free clarification of beer. PROFi system technology is a co-operation between Pall Food and Beverage and GEA Westfalia Separator GmbH. It is the engineered result of significant Research and Development built on the extensive and unique brewing experience of the two companies. 

The PROFi system technology offers a smart solution to the demands of the brewing industry offering complete DE-free clarification with direct value to the brewery.

仕様

PROFi System Process

Stabilized beer from fermentation / maturation is pre-clarified with a high efficiency centrifuge, which ensures gentle treatment of colloids and minimal oxygen pick-up. Bulk yeast is separated from the beer and discharged with a high percentage of dry solids. This membrane pre-clarification delivers longer filtration cycles and enhanced system economics.

Fine filtration of beer in the membrane unit is continuous, due to membrane blocks alternating in filtration and regeneration. This design ensures constant filter availability and smaller system sizing, reducing both capital and operating expenses.

Forward flow module emptying with CO2 enables a fast product change and flexibility without pre or post run blending / loss. Beer protein stabilization may be performed upstream of the centrifuge with silica gel, while polyphenol stabilization is accomplished either upstream of the centrifuge with one way Polyvinylpolypyrrolidone (PVPP) or downstream of the membrane unit with regenerative PVPP or other methods. Ideally the PROFi system is combined with a stabilization system which also runs in a continuous mode.

Filter Media

At the heart of the PROFi membrane system are the highly engineered membrane module inserts which cover the hollow fiber membranes. The membranes consist of polyethersulfone (PES), which is a reliable, inert material widely applied to beer filtration. The membranes, in combination with the module design, guarantee high mechanical strength resulting in a long service life and optimized costs.

The module design includes:
  • High porosity membrane with highest loading capacity for beer colloids
  • Module insert designed for stainless steel housing enabling sanitization up to 74 °C (165 °F) and pressures up to 6 bar (87 psi)
  • Fast module exchange
  • High mechanical, thermal and chemical resistance
  • Reliable yeast reduction
  • Reproducible in-situ Module Functioning Tests

Commercial

A PROFi membrane system is an investment into cost effective beer clarification, sustainable technology and brewery production flexibility. The cost saving potential depends on the brewery specific situation and has to be calculated case by case.

PROFi Batch System

In order to make DE-free membrane technology accessible for breweries with a lower annual production capacity on an economically attractive basis, the PROFi Batch System was developed. The aim was to use the existing and proven PROFi system technology and design with minor modifications to the installation and process. The PROFi batch system fulfils the technological and economic requirements of breweries with an annual production capacity between 400,000 hl and 1,300,000 hl.

The main difference between the standard PROFi system and the PROFi Batch system is the batch-wise operation mode. Filtration and regeneration take place one after another for the complete PROFi system. All the added benefits customers achieve by using the PROFi technology remain unaffected.

PROFi Membrane System - Batch Operation


The system consists of 1 or 2 module blocks with 20 or 28 modules, depending on the required total flow rate.
