Lauter tun, mash filter and continuous mash filtration

Lauter tun, mash filter and continuous mash filtration system from one source

Lauter tun, mash filter or a continuous mash filtration system? The answer depends on the overall concept and the structural environment in which the brewery operates. ZIEMANN HOLVRIEKA customers have the choice between three alternatives for the lautering process:

  • See more about LOTUS by ZIEMANN lauter tun
  • See more about BUTTERFLY by ZIEMANN membrane mash filter and DRAGONFLY by ZIEMANN chamber mash filter
  • See more about the continuous mash filtration system NESSIE

We have been offering mash filters and lauter tuns alongside each other for decades. This range is now complemented by a third procedure, which is revolutionizing the entire brewing process. Each one developed to demonstrate the familiar innovative strength at the highest level of efficiency. This depends on which technique fits in better with the brewery environment. In order to facilitate your decision, you are welcome to download our white paper on lautering technologies free of charge.

We have always given priority to individual and tailor-made solutions. In this way, we can design a concept that allows the brewery optimally to respond to the market development.

LOTUS lauter technology

LOTUS lauter tun saves water and enables higher first-wort concentration

T3123 Industries Beer Bewhouse Lautering 1The LOTUS lauter tun saves water ...

The new LOTUS lauter tun offers the following advantages:

  • Up to 50 percent fewer ring pipes
  • Up to 70 percent fewer run-off pipes
  • Up to 55 percent less water volume in the piping area
  • Higher first-wort concentration
  • Effectively more sparging water available

Furthermore, the required performance and wort qualities are safely achieved. The desired yield is also achieved when using wort types with a high extract content, as for high-gravity brewing or for some very strong craft beers. The outlet area of the LOTUS lauter tun can be easily increased to 2.5 m2 due to the false bottom distance and the flow-optimised tulip shape. The run-off pipes are no longer distributed across the lauter surface like honeycombs, but are integrated into the bottom directly above a single lauter ring.

The LOTUS lauter tun therefore needs up to 70 percent fewer lauter tulips and 50 percent fewer pipes. The lower pipe volume reduces the water volume required in this area by approx. 45 to 55 percent. The cost of the associated measuring and control systems is reduced accordingly.

Flexible lauter work

All relevant parameters determining the lauter characteristics, such as suction pressure, turbidity, flow rate and yield, are exactly equivalent to those of previous high performance lauter tuns, in spite of the simplified LOTUS design. This also holds for different types of grist and original wort and the processing of more than 70 percent wheat malt; as verified by scientific work on a pilot scale.

In short: LOTUS facilitates very flexible lauter work, processes various types of grist and original wort and is very attractive with regard to the investment required. LOTUS is particularly suitable for the globally booming sector of handcrafted special beers, as supported by an impressive list of references.

The new LOTUS design with its reduced number of run-off pipes and only a single lauter ring is offered for lauter tun diameters of up to 8 meters; above which ZIEMANN use the traditional lauter tun design or the proven mash filter.

Mash filters enable high-speed filtration

Thin layer mash filter and membrane mash filter provide excellent wort qualities and highest yields

T3123 Industries Beer Bewhouse Lautering 3The membrane mash filter BUTTERFLY allows the processing of even small batches.

BUT TERFLY membrane mash filter

The BUTTERFLY membrane mash filter is ideally suited for craft brewing companies. The mash filter with its separation set-up allows for processing of small batches. Moreover, alternative cereals or starch sources, as well as wort types with high extract content, can easily run off. Therefore, BUTTERFLY offers maximum flexibility for each recipe design. In addition, BUTTERFLY achieves very good yield values at low sparging water volume.

The BUTTERFLY membrane mash filter is available for brewhouses with a cast-out wort volume starting at 150 hl. BUTTERFLY can be integrated into an existing brewhouse as a stand-alone solution. For its commissioning, only a signal exchange is established in the control system of the existing brewhouse. Therefore, BUTTERFLY can easily be installed as the sole or additional lautering device.

DRAGONFLY by ZIEMANN chamber mash filter

DRAGONFLY  accomplishes 16 brews per day with ease. They require 30 percent less investment costs and take up a minimal amount of space. These are just the basics. DRAGONFLY excels in a wide range of additional features:

  • Efficient design: DRAGONFLY is designed as thin-layer chamber mash filter with large filtration areas. The thin-layer chamber mash filter permits more brew sequences than ever before.
  • Minimum maintenance costs: The omission of membranes increases service reliability and reduces maintenance costs to a negligible value.
  • Effective technology: This new technology provides excellent qualities of the wort qualities, which boast lowest turbidity values and highest yields.

Based on its design and process control, our mash filters are ideal for high gravity brewing and for the processing of raw grains. The mash filters are designed as thin-layer filter press. The depth of the individual chambers depends on the composition of the mash to be filtered.

The press frame is fitted with a high-performance mechanical system; this provides extremely short idle times in “opening“, “removal of spent grains“ and “closing“. This provides more time for the lautering process.

Continuous mash filtration system NESSIE

Increased flexibility in terms of raw materials and batch sizes, reduced lautering time

With the continuous mash filtration system NESSIE, the mash is separated into wort and spent grains and the spent grains are sparged in order to obtain the extract. With this procedure, the lauter wort is obtained in a dynamic process. The mash transfer time corresponds to the lautering time. The separation of the mash is carried out via four filter units in cascade arrangement, in which the rotary disk filters perform the separation of wort and spent grains. The sparging of the extract is carried out in parallel using a turbulent counterflow extraction. The sparging water is injected via fine nozzles in the transition between the filter units. The flow direction of the water is principally opposed to the flow direction of the solids.

The main advantages of NESSIE are as follows:

  • 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
