This system applies to PVPP stabilization treatment after beer filtration, thus to prolong the effective preservation period of the beer. The noteworthy feature are reliable operation with a special parts named candle-cartridge for filter elements; Little loss of PVPP, automatic regeneration and recovery, convenient recycling, very economy; Simple and efficient cleaning system, rinse of candle-cartridges on the opposite with good results.
The structure and features
This system is mainly composed of the main filter tank, PVPP mixing/dosing devices, steam heating systems, CO2 back pressure protection device, cleaning device, pipeline system and control system.
The main filter tank is the main machine of the PVPP stabilizing filter. It consists of candle cartridges (filter elements), hole board for installing candle cartridges, sealed and impacted devices for tank cover, cleaning devices and into liquid allotter, slight glasses, operating platform and components. PVPP medium adsorption to polyphenol substance in the beer and PVPP regeneration are accomplished in the filter tank.
PVPP mixing/dosing devices provides evenly suspended mixture of PVPP and water to the main filter tank. It has two functions: One is precoat filtration layer, in other word rapidly provides PVPP mixed liquor to candle cartridges in the filter tank in order to form precoat layer for PVPP filtration. Two is dosing, that is to say that continuously provides PVPP mixed liquor at accurate dosage to the filter tank according to filtration technics until the filtration course ends.
The system are also equipped with automatic steam heating system which heat up and sterilize and keep warm to PVPP in the filter tank, and also equipped with CO2 back pressure protection device which effectively prevents the outside oxygen caused by dosing invading the beer body.
