In beer factory, the beer filtration is a very important process in production, which is related to the appearance and taste of beer, as well as biological stability and abiotic stability. At least during the shelf life, the appearance of the beer does not change, so as to ensure the perfect appearance and quality of the beer.
In mature beer after fermentation, a small amount of coagulant such as yeast and protein are suspended in the liquor, causing the beer to be cloudy during storage. Therefore, it must be removed by a filtration process. Beer filtration is a physical process that uses filter media to separate and remove the tiny particles suspended in the beer from the liquor, so that the beer is clear and transparent without suspended solids.
At present, the commonly used method is to use diatomaceous earth as a filter aid to filter the yeast in beer, but there are many beer filtration equipment, but the main problems are oxygen exposure, bacteria infection and pipe non-stop when discharging and washing filter element. therefore, the best way to solve these problems is that:
The candle filter is diatomite-coated filter. It uses a candle filter cartridge. When working, it needs to coat the diatomite layer on the candle filter tube—diatomaceous earth (the process of pre-filtering is to pre-coat the diatomite filter on the filter medium then filter the beer). When the beer is filtered for a period of time and the resistance of the filter increases, blow back with air to discharge the yeast, colloidal sediment, bacteria and existing pre-coating diatomite trapped by the pre-coated diatomite on the tube of candle filter.
For these purposes, Yuwei candle filter is very suitable for this condition. The stainless steel filter cartridge, can be backflushed, can be backblow, also it can discharge automatically.
