Kieselgur candle filter
Efficient filtration of beer varietiesWith the M&L Kieselguhr (diatomaceous) Candle Filter, all beer varieties can be effectively filtered. The result of reliable and cost-efficient filtration is brilliantly clear beers with the lowest levels of turbidity and oxygen. The diatomaceous earth candle filter remains one of the most economical filtration systems and also offers the option of reuse when switching to diatomaceous earth-free, regenerable filter aids.
How M&L Candle Filters work?Stainless steel filter candles are used to achieve excellent filtration results. They serve as a support layer for diatomaceous earth and are first pre-coated with coarse diatomaceous earth and then flushed with fine diatomaceous earth. The pre-coating with coarse diatomaceous earth takes 15 minutes and forms the basis for filtration. Oxygen-free water is introduced during the process to establish a stable diatomaceous earth layer on the candles.
The second filter layer, consisting of medium and fine diatomaceous earth, is applied in a similar manner and adjusted to specific requirements. After pre-coating, the degassed water, along with unfiltered beer, is pushed out of the filter. This mixture is collected in a pre-run buffer tank and immediately reintroduced into the filtration.
M&L‘s recommended process technology ensures extract losses of less than 0.3%. Throughout the entire filtration process, diatomaceous earth is continuously added to the unfiltered beer at the filter inlet to prevent blockages and rapid pressure increases, enabling longer filtration cycles.
At the end of filtration, the beer is discharged with degassed water. If the original wort in the pressure tank falls below the required value, this mixture is collected in the pre-/post-run buffer tank and reintroduced during the next filtration.
Why should you choose our Kieselgur candle filter?
- Customized design and sizing tailored to the required task or filtration performance.
- M&L‘s newly developed metallic filter candles are advanced, maintenance-free, and durable. The long, slender design of the filter vessel ensures a reduced volume of the beer-water mixture phase, as well as during product changeovers, significantly minimizing beer loss.
- Excellent filtration quality with exceptionally low turbidity levels and absolute cost-efficiency.
- Short commissioning times
- Easy integration: The system is pre-assembled, pre-wired, and tested.
- Fully automatic operation: Intuitive control with the corosys compass allows for effortless operation, or the system can be fully integrated into your process control system.
- Everywhere in view: With our Smart Machine operational data acquisition, you have access to operational data and reports from anywhere.
