The Ultimate
Brewing Solution
Efficiency, taste, and cleanliness – these are the keywords regarding this ultimate brewing solution. ULTROM is revolutionising the brewing process. A horizontal mixing drum, in combination with Ultrasound, enables new possibilities. Homogeneous stirring, a faster hydrolysis and a better and unique taste of the beer are only a few of the benefits of this new technology.

Proof
The degassing caused by the ultrasound improves extract yield. In addition, gentle cavitation prepares the carbohydrates optimally for hydrolysis, so the enzymes work not only faster but also under better conditions. With homogeneous stirring and mixing the malt in the mash, cavitation is evenly distributed. Low resistance in the stirring process allows the process to be stopped and started at any time. This so called “rewash” becomes very useful when a vacuum or compact mash hinders the lauter process or any technical issue forces stirring to stop. This particular feature provides the possibility to rewash the malt at any time and thus gain higher yield out of the malt.
Efficiency
ULTROM achieves a brewhouse efficiency of over 95%*. The drum is fully insulated and heats the mash from all sides: fast heating, an even, stable temperature and high energy efficiency. As mashing and lautering take place in ULTROM, no solids need to be pumped – only the wort goes to the kettle. While the wort is boiling, the next brew can already start in ULTROM. This saves time and energy. Mashing-in is easier too: no dough balls form in ULTROM, so the malt can be added faster and hassle-free.
* Relative to the laboratory extract, as calculated in the US. Based on the grain bill, as is standard in Germany (laboratory extract approx. 80%), this corresponds to over 76%.
Compactness
This ultrasound barrel requires no headspace and is thus 35% more compact than conventional two or three vessel brewhouses. Furthermore, as the vessel is closed, no vapour extraction system is required. The ULTROM is closed, coated, and filled to the top, hence it is more economical than any other brewing system.
Flavour
Ultrasound degasses brewing water and mash, lowering the dissolved oxygen. Together with the closed drum, filled to the brim, this means less oxidation during mashing. Oxygen-dependent enzymes are slowed down: lipoxygenase, which leads to staling flavours, and ascorbate oxidase (AAO), which breaks down ascorbic acid. This better preserves the malt’s natural antioxidants. The result: a fresher taste, better flavour stability and aroma that is preserved in the mash – particularly valuable for non-alcoholic beers. Because of the covered round shape of the ULTROM and its comparatively small open valves at the top, if CO2 must be added it would not escape easily.
Quality
This Swiss patented brewhouse stands for quality and reliability. Ultrasound technology of its finest from Weber Ultrasonics AG (Karlsbad near Karlsruhe, Germany) is known as state of the art and appreciated by customers all around the world. The device is built to last thanks to the specialized welding. In existing breweries, ULTROM replaces the mash and lauter tun, or it is available as a complete, modular brewhouse.
Clean
Thanks to its rotating drum, ULTROM cleans itself with little effort and minimal cleaning agent – the cleaning solution reaches every surface. No shovelling of spent grains is needed: they slide out easily at the end of the drum into a container.
