Filtration of wine


   

Main applications of cartridge membrane filtration in wine-making

? Defertilizing filtration of wines in cold sterile filling conditions

? Removal of residual opalescence in hot filling conditions

? Fine filtration of flushing water and washing liquors

? Sterilizing filtration of air and carbon dioxide, "breathing" of tanks

Required conditions for faultless final membrane filtration

? Careful preliminary preparation of wine material

? Prefiltration of wine through a filter press incorporating a high-quality cardboard

? Availability of sterile service media

? Carefully prepared deferilized vessels provided with filters for sterile breathing

? Careful sterilization of equipment and all materials coming into contact with wine

? Good sanitary state of the manufacturing plant

Membrane filtration is the most common technique used for microbiological stabilization of beverages with no use of chemicals or heating. In contrast to pasteurization, cold stabilization preserves aroma, taste and the fine structure of wine.

EPM (ЭПМ) membrane filters ensure complete retention of wine-spoiling microorganisms.

EPV (ЭПВ) fine filters displaying a high dirt-holding capacity and a long service life ensure excellent protection of the membrane element and extension of its service life.

 

 

EPM.PS (ЭПМ.ПС) new generation cartridge filter incorporating a polyethersulfone membrane

Technofilter presents EPM.PS (ЭПМ.ПС) new generation cartridge filter incorporating a polyethersulfone membrane, specially developed for defertilization of wine and beer that can withstand multiple washing, reconditioning and sterilization.

Features

Advantages for the user

The filter incorporates a reliable pleated polyethersulfone membrane offering superior performance

? Broad chemical compatibility (pH 1 to 14)

? Excellent thermal stability (up to 100°C for water)

? Low binding capacity with respect to albumens and proteins

? Extended service life resulting from increased surface area (up to 0.75 m2/250 mm)

High retention efficiency with respect to bacteria and microorganisms (99.98%)

? Available with pore sizes 0.65, 0.45 and 0.2 μm. Guaranteed removal of yeast cells, mold fungi and bacteria before bottling

Pronounced asymmetric pore structure and increased overall porosity of the membrane

? High filtration rate and low differential pressures reduce financial costs

Stronger structure, longer service life

? Reliable preservation of filter integrity in severe operating conditions

? The possibility of multiple sterilization ensures cost-effective operation of the filter

100% control for guaranteed quality, integrity testing

? Microbiological safety - penetration of retained particles and microorganisms into the filtrate is ruled out

? Guaranteed integrity and effective operation of the filter

? The filters can be subjected to a special integrity test in the course of operation

Non-toxic, apyrogenic

? The filters have undergone extensive testing and have been certified for use in food industry. The filters are produced in accordance with a certified quality management system ISO 9001:2000

Effective prefiltration

Most filling lines use two-stage filtration of wines before filling.The "prefilter-final filter" combination increases the reliability of the process, ensure maximum filtration rate, a long service life and cost-effectiveness of the filtration system. To ensure high-quality prefiltration, Technofilter recommends pleated depth filter cartridges EPV.S (ЭПВ.С) and, EPVg.P (ЭПВг.П) that can be repeatedly reconditioned.

Filter holders for liquid filters

Technofilter presents DS-3, DS-5 and DS-8 (ДС-3, ДС-5 and ДС-8) filter holders (NEW series) made of 12Kh18N10T (12Х18Н10Т) stainless steel.

Features

? High-quality finishing of inner and outer surfaces

? Easy access to internal cavities for visual inspection and washing

? No hidden or hard-to-reach cavities owing to extra lightweight spacer

? No stagnant zones

? Complete evacuation of liquid through drain valve

? Increased accuracy and finishing of nests for adaptors and of surfaces for sealing parts ensure high impermeability of boundaries between the feed, the filtrate and the outer environment

? Simplified on-site assembly owing to hinged connection of pipe sockets to the base. The filter holder is provided with pressure gages for monitoring of flow resistance.
