Filter aids for innovative beer filtration
Krones celcare – a compressible filter aid on a cellulose basis – has been added to the KIC Krones product range. With this product, KIC Krones is reacting to a new system developed by Krones for precoat filtration with alternative filter aids. It not only stands out thanks to its excellent filtration results but also with a view to economic and ecological aspects: on the one hand, filter aid consumption is reduced the longer the filter service life. On the other, with cellulose, Krones celcare is using a natural, renewable raw material and is thus not subject to any limitations when it comes to its recycling or use as field fertilizer after filtration.
Best filtration results
The appropriate process to do so was developed by the brewing technology experts at Steinecker in collaboration with KIC Krones. The necessary differential pressure is regulated here by a bypass system in which the filtrate is guided into the unfiltrate supply at the filter. While filtration is in progress, the dosing quantity of Krones celcare – following a start-up phase in which the cake is built up quickly – can be reduced considerably. Therefore, in practical terms, this means: the consumption of filter aids is reduced the longer the service life. The permeability of the filter cake can also be precisely controlled, leading to excellent turbidity results for the widest range of unfiltered beer types.
