Purpose of the Visit
Beer filtration test performed – filter trap with Eaton Duragaf (extended life) and Sentinel filter elements to evaluate service life compared to current filter elements used. Tests were performed after diatomaceous earth and PVPP filters.
Physical stabilization prevents the formation of mists and deposits after bottling the beer. This objective is achieved by removing certain proteins and polyphenols, compounds that cause turbidity, by means of adsorptive materials, such as diatomaceous earth and polyvinylpolypyrrolidone (PVPP), arranged in a pie shape on screen or candle filters.
It is common for a small part of the diatomaceous earth and PVPP to pass through the support elements of the cake, which must be captured by clarifying filters in order to prevent them from remaining in the beer after it is bottled. Other turbidity-causing contaminants normally found in beer can be caused by: foreign agents in the raw material, particles released from equipment, tanks, instruments and components, residues generated in the process (eg dried foam), live or dead microorganisms, etc.
2. Application description
Bag filter elements were installed after diatomaceous earth and PVPP filters.
The system consists of two housings with 4 bags after the earth filter and two more housings with 4 bags each. During filtration, only one of them is in operation and the other is on “stand by” and is aligned when the filter elements clog. In this way, filtration is not interrupted during production. Before using Eaton filter elements, they were using NB0005EES2C filter elements.
3. Results obtained
4. Financial gains
4.1 Annual consumption of filter elements (parts)
4.2 Gasto anual com elementos filtrantes
4.3 Expenses with the arrangement of filter elements
Note: assumed the value of R$ 0.50/pieces for disposal of filter elements.
4.4 Total annual savings
5. Recommendations on financial gains
Evaluating the results obtained at the Jacareí plant, we have a great opportunity to replicate the work in other Ambev units. The gains obtained can be even greater if we apply the Eaton Duragaf filter element to other units.
We recommend that this same work be done in another Ambev plant that has a production volume similar to Jacareí to certify the gains obtained.
We are available to carry out this work.
