Three Lautering technologies for maximum efficiency, short brewing cycles and highest yields
Lauter tun, mash filter or continuous mash filtration system? The answer depends on the overall concept and the market environment in which the brewery operates. ZIEMANN HOLVRIEKA’s customers can choose between three alternatives for the lautering process:
LOTUS by ZIEMANN lauter tun
The LOTUS by ZIEMANN lauter tun fulfills the requirements in terms of speed, yield and flexibility like no other.
Fastest lauter tun
With LOTUS you are able to brew up to 14 brews a day. This is possible by combining sophisticated engineering, optimized lautering technology and our intelligent “Dynamic Lautering Mode”.
The “Dynamic Lautering Mode“ (DLM) is an integrated process control that reacts dynamically to the changing raw material and grist qualities. For this purpose, the lautering parameters (e.g. flow rate) are adjusted depending on the suction pressure so that the maximum lautering performance is achieved and the filter layer (spent grains cake) is protected from compression. DLM guarantees the optimal operation of your plant with your raw materials.
Less measuring instruments and simpler control technology
Due to the optimized false bottom design, the filtration area for every outlet can be easily increased to 2.5 m². This significantly reduces the number of run-off pipes. Even with large lauter tuns it is possible to use only a single lauter ring. This results in water savings, less measuring instruments and a simpler control system.
Less pipes reduce the water volume by up to 55%. This volume is now available as sparging water for extraction, resulting in a higher yield.
Flexible in terms of brew size and raw materials
The LOTUS lauter tun processes a great variety of grist loads (+10%, -50%) and therefore a high flexibility. The choice of raw materials also offers many possibilities: up to 70% of wheat malt can be processed, up to 50% of sorghum or up to 40 % of other alternative starch sources. The LOTUS lauter tun processes worts with an extract content of up to 21°P. Thus, particularly strong special beers can be brewed or high gravity brewing can be used.
Fast and easy adjustment of the knives
A special feature of the LOTUS is the fact that the knives can easily be adjusted. This allows you to change their position to the requirements of the lautering process.
DRAGONFLY and BUTTERFLY by ZIEMANN mash filters
ZIEMANN HOLVRIEKA is the only supplier offering both mash filter technologies: the DRAGONFLY chamber mash filter and the BUTTERFLY membrane mash filter. Although they differ in details, they have common advantages:
Fastest mash filter
Mash filters from ZIEMANN HOLVRIEKA are considered the fastest. With DRAGONFLY up to 16 brews per day are possible, with BUTTERFLY up to 14 brews per day. This is due to many reasons: the press frame is equipped with a high-performance mechanical system allowing extremely short idle times for “opening”, “removal of spent grains” and “closing” and leaving more time for the lautering process. Furthermore, each side of a chamber is equipped with a filter cloth, resulting in a double filtration area leading to a higher filter performance in a shorter time.
Flexible in terms of brew size, first wort concentration and raw material selection
Mash filters from ZIEMANN HOLVRIEKA offer great flexibility in terms of the brew size: thanks to a separation set, which is positioned manually, even smaller batches can be processed. Furthermore, first wort concentrations of up to 25° Plato are possible. With regard to the raw material selection, you are free and can use more of your local resources: even 100 % of un-malted cereals (such as rice) and a wide variety of other starch sources can be processed.
Spent grains removal without manual intervention
The spent grains removal is fast and fully automatic. The dry and compact spent grains cake drops off easily with no manual intervention.
High extract yield even at high number of brew cycles
The high extract yield is also achieved due to the fact that ZIEMANN HOLVRIEKA relies on a sophisticated sparging technology, which is carried out diagonally through the spent grains cake from bottom to top, or from top to bottom.
More brews possible between the CIP cycles
Two features of our mash filters make sure that the filter cloths do not have to be cleaned as often:
- From brew to brew, the sparging water direction alternates and is set in the opposite direction. This leads to a self-cleaning effect of the mash filter cloths.
- Mash filters from ZIEMANN HOLVRIEKA withstand greater internal pressures. This supports a longer service life.
Compared to a lauter tun, mash filters require significantly less space. Even grist loads of up to 24 tons of malt can be processed with only one DRAGONFLY.
Long service life
The filter cloths have a guaranteed service life of 2,500 brews whereas the membranes, 12,000 brews.
DRAGONFLY by ZIEMANN chamber mash filter
BUTTERFLY by ZIEMANN membrane mash filter
The membranes are moved with the pressing medium water. The first wort is pressed out from the spent grains cake in both directions. This is one of the reasons why you can achieve higher yields with our mash filter. Our technology allows you to obtain your remaining extract even with the least amounts of sparging water and there is little to none weak wort produced.
Continuous mash filtration system NESSIE by ZIEMANN
All types of starch sources can be processed, which offers cost advantages and the ability to use alternative local starch sources.
Your existing mill system can be easily integrated and reused; the grist composition plays a secondary role for NESSIE.
Due to the short contact time of the mash in NESSIE: the wort contains less polyphenols from the malt. In addition, NESSIE preserves natural ingredients in the wort, while undesirable ingredients remain in the spent grains.
NESSIE reduces the process time by up to 30%. This means less washing out of undesirable ingredients, up to 40% less polyphenols, longer shelf life, improved flavor stability and higher beer quality.
A more efficient extraction and separation ensures higher yields of the grains resulting in cost savings.
NESSIE provides the basis for the decoupling of the wort streams, which can be subsequently optimized and the
The brew sizes no longer depend on the size of the lauter tun: the brewmaster can brew even the smallest batches.
A hitherto unachieved first wort concentration is possible: up to 32 °P!
An enormous variety of beers can be brewed.
- Freedom of choice in terms of cereals and all types of starch sources
- More flexibility during the brewing process
- Shorter process time
- Higher yields of hops and starch sources
- Less undesirable ingredients such as polyphenols
- Improved wort quality due to more zinc and fatty acids
- More vital fermentation
- And much more
