Final filtration allows you to retain particles and bacteria in order to increase shelf life of beer.
Purposes of filtration
Unpasteurized beer is becoming more and more popular, but its production requires changes in the filtration scheme.
The generally accepted filtration scheme for the production of pasteurized beer is as follows:
This scheme does not guarantee the product sterility. Even with sterilizing cardboard, sterility is guaranteed at the outlet of the filter only. When the product passes through the bright beer tank and pipelines to the filling line (bottling), secondary insemination occurs.
NPP Technofilter recommends using an additional filtration stage – final filtration before filling. Final filtration allows you to retain particles and bacteria, thereby significantly increasing the shelf life of beer.
Proposed scheme:
or a scheme with replacing the filter presses with a cartridge trap filter:
Recommendations for filter cartridges
Filter cartridges for filtration before bottling of unpasteurized beer
Cartridge filter EPV.S is designed for high-quality filtration with the possibility of multiple flushing and regeneration.
EPV.S –is a death corrugated filter cartridge based on microfiberglass material with a large surface area and low resistance to flow. The filtration efficiency (practically at the membrane filtration stage) is achieved by the high adsorption capacity of the glass fiber as well as increased filter capacity.
