Barley malt and cereal grains are received in bulk and transferred to silos for storage. A sample from each batch is analyzed to determine cereal moisture and starch content. Malt cleaning and de-stoning occur prior to milling.

Barley malt is milled in conventional roller mills to produce grist. Alternatively, GEA provides wet-conditioned milling by MILLSTAR®, offering improved lautering efficiency. Milling and mashing-in can thus be combined in a single, non-ATEX dust-free and hygienic step.

Grist and water are mixed in a grist hydrator or pre-masher. The addition of a Mash Conversion Vessel increases mashing flexibility or can be added as a de-bottlenecking upgrade. Gentle mash transfer by low-shear Mono type pump is a novel feature of GEA mashing systems.

The lauter tun is the heart of the mash house, responsible for the extraction of sugary wort from the cereal mash. The system offers flexibility and is optimized to manage conversion yield, wort gravity and clarity, oxygen pick-up, cycle time and extraction efficiency.

Wort is combined with yeast in fermenter washbacks to convert sugars to alcohol containing wash. Hygienic fermenter design is enhanced with jacketed or external coolers – for attemperated fermentation control, improving alcohol yield while reducing energy and water use.

Wash is distilled in wash stills to produce high wine. This distillate is further concentrated in spirit stills to produce new make spirit. Energy savings by TVR or MVR heat pump techniques are used, while waste heat recovered from the condensers aids sustainability.

Thermal energy is recovered from the still condensers and stored as hot water in an energy recovery tank-accumulator. Heat is therefore provided as sustainable energy for mashing and sparge water preheating along with other uses like CIP and syrup evaporator heating.
