Stabilization (Beer)

PVPP

Divergan® is a polymer (cross-linked PVP) from BASF that is used for beer stabilization. It selectively adsorbs and removes the polyphenols responsible for turbidity while maintaining taste and character of the beer. Thereby Divergan helps to keep beer clear during storage and to increase its shelf life. Especially in regions subject to climate extremes (e.g., tropical countries or very cold regions), the use of Divergan guarantees constant colloidal stability. Divergan is completely separated from the beer during filtration. Thus, Divergan is not an additive and does not require to be declared on the label. The single-use product Divergan F can be used in existing filtration lines, and is highly efficient even at low dosages. A combination with other beer stabilizers (e.g., silica gel) is readily possible. Where the size of the brewery is appropriate, the installation of a regeneration line can be worthwhile. The cost-effective use of regenerable Divergan RS with its low loss rates has proved to be very efficient for many years. Approval for Divergan is available in all countries with a significant brewing industry

Silica Gel

The chemicophysical shelf life of beers is still a key factor, since consumers expect the quality of the beer to remain unchanged during storage. Silica gel, a high-purity amorphous silicon dioxide, is used for the selective adsorption of protein substances that cause hazing in beer. With the BECOSORB® Eaton’s Begerow® Product Line offers three different silica gels that have been specially developed for stabilising beer

•BECOSORB 1000: a xerogel with max. 10 % moisture content.

•BECOSORB 2500: a saturated xerogel with approx. 40 % moisture content.

•BECOSORB 6000: a hydrogel with approx. 60 % moisture content.

BECOSOL® 30

This 30 % silica sol has been specially developed for beer clarification and filtration improvement in the brewing industry. The effect of BECOSOL 30 is based on the tendency of the SIO2 particles to agglomerate with haze and protein substances in the beer. This improves the clarification effect and the filtration characteristics of the beers.

Filter cartridges are used for the clarification, fine and membrane filtration of liquids. Areas of application include particle separation through depth filter cartridges and sterilising filtration through separation of microorganisms with membrane filter cartridges.

Membrane filter cartridges and depth filter cartridges are distinguished as follows: Membrane filter cartridges are always pleated, since a large surface is required. They are used for sterile filtration. Depth filter cartridges are available as pleated or wrapped types. In wrapped depth filter cartridges the individual filter layers become increasingly finer from the outside to the inside. They are back-washable and mechanically more stable. They are used for clarification and fine filtration and for protecting the membrane filter cartridges. The most important products are listed below.

Membrane Filter Cartridges:

BECO® MEMBRAN PS Beer

BECOPAD® - Filtration with brilliant results!

BECOPAD is an innovative depth filter medium for the filtration of beverages. In contrast to conventional depth filter sheets, which contain both cellulose and mineral components, BECOPAD consists only of certified cellulose produced in sustainable plantations. Due to its composition, after filtration BECOPAD is suitable for composting without restriction.

Since BECOPAD consists of high-purity organic fibres, no undesired constituents are released into the product to be filtered. The purity and naturalness of the beers to be filtered remains unchanged. Due to the exceptional flushing characteristics of BECOPAD the water consumption for pre- and backwashing can be reduced by up to 50 %. This saves resources and significantly reduces filter setup times. The robust product can be applied quickly and easily with little effort.

Since cellulose media are more compactable, they seal the plate and frame filter almost completely. As a result, drip losses are almost totally avoided and beer loss and mould growth around the edge are a thing of the past.

The cellulose fibre used for BECOPAD is produced based on an innovative process. It enables sterile filtration with cellulose media for the first time. The separation of bacteria, yeasts and particles is based solely on deep action in the cellulose fibre matrix. High electrokinetic adsorption, which characterises conventional depth filter sheets, is no longer required. Beneficial components, such as bitter substances and colour, are left in their original state.

The grading of BECOPAD from coarse to sterile filtration provides optimum choice according to filtration requirements. BECOPAD for coarse filtration can already reduce significantly microorganisms. In the sterile range the user is offered maximum bacterial retention rates. This high bacterial retention in combination with a significantly improved overall performance was the key reason for BECOPAD winning coveted prizes and trade press awards.

BECOPAD makes filtration significantly more cost-effective.

Description of its innovative character:

• Gentle filtration: Preserves valuable color and flavor (hop oil, anthocyanins)

• Saves time and money: Increases efficiency by up to 20 %

• High safety: Microbiologically unsurpassed retention

• Almost drip-free filtration: Minimizes product loss

• Produced from pure cellulose: Natural and 100 % biodegradable

• Environmentally friendly: Saves up to 50 % of water during neutral rinsing and backwashing

BECO® ENDURA® support sheets

BECO ENDURA is a washable and reusable support sheet for precoat filtration in kieselguhr frame filters. It offers a particularly high overall performance. High wet strength and an optimised surface enable a service life of up to 30 precoat cycles, depending on the liquid to be filtered and the filter aid used.

BECO ENDURA has been specially developed with the stringent requirements of precoat filtration in mind. Its high strength ensures consistent filtration characteristics over its entire service life. The sturdy and uniform surface structure allows straightforward and damage-free removal of the kieselguhr. The homogeneous fibre structure enables uniform flow through the support sheet. The kieselguhr is optimally precoated and blind spots that may occur if the distribution is inhomogeneous are avoided.

CLEARGAF filter bags in conjunction with the SENTINEL^® ring form a filter bag system that meets the strict requirements of the food and beverage industries.  This includes several bag types that are the only bags on the market to offer the following features:

• Processing of materials in accordance with FDA requirements (21CFR177)
• Compliance with EC Regulation 1935/2004 and EC Directive 2002/72/EC
• Independent tests and certification
• Special individual wrapping and storage

BECOGUR^®

BECOGUR are high-quality, high-purity, filtration-active kieselguhrs for precoat filtration. BECOGUR is originated in America and mainly consist of the cylindrical/barrel-shaped freshwater diatom Melosira granulata. The benefits of this diatom lie in its three-dimensional shape, its tiny pores and its very high mechanical stability due to its barrel-shaped structure. BECOGUR is available in five grades that can tackle any filtration task.

• BECOGUR 100: Very fine kieselguhr providing maximum filtration efficiency for "polishing"
• BECOGUR 200: Fine kieselguhr with high filtration efficiency for fine filtration.
• BECOGUR 1200: Medium fine kieselguhr which offers both together, medium fine clarification characteristics and high throughput values, used therefore especially in the brewing industry.
• BECOGUR 3500: Coarse kieselguhr for clarifying liquids heavily loaded with turbidities.
• BECOGUR 4500: Very coarse kieselguhr for quick clarification of very turbid liquids.

Depending on the respective filtration application, it may be advantageous to mix different BECOGUR grades. Improved filtration performance can frequently be achieved by combination with other filter aids, e. g.

BECOLITE^® (filtration perlite)
BECOCEL^® (filter cellulose)
BECOFLOC^® (filter additive for pre-coat filtration)
