Steinecker Calypso combines a vortex pool and a cooling boat into a "vortex boat"

The Bischofshof brewery in Regensburg, Germany, has entered the final stages of the modernization of the traditional brewing plant as it builds its new saccharification plant. Krones AG in Neutraubling, Germany, first made a major technical breakthrough: Steinecker's Calypso “vortex boat” combines the advantages of traditional cooling boats with hot mash processing. In short: Calypso is a modern vortex pool with a post-purification system.

Circular cylinder in round cylinder

From a structural point of view, Calypso is a vessel with a built-in section in a cylinder, using its inner zone as an optimized vortex pool. There is a new type of inlet on the vortex pool. From this inlet, the mash is tangentially fanned into the vortex pool at the optimum flow rate. After the hot turbidity separation, the mash in the lower pan of the vortex pool first leaves the vortex pool from the side and then at the end.

Unlike conventional vortex pools, mash does not enter the chiller directly, but instead flows to the outer area of ​​Calypso for post-evaporation. The annular chamber and its two insulating side walls are heated during the cooking phase via hot mash. Through an annular conduit between the two side walls, the hot turbid separated mash falls onto the superheated isolated side wall and then flows away as a thin layer of liquid. The large surface area thus formed not only allows the DMS to easily dissipate, but also removes other unnecessary aroma components. Finally, the mash flows down into a small container and into the plate cooler.

With Calypso, mash reduces the cooking in the pre-cooking stage in order to reduce the DMS before entering the vortex pool. DMS is easily removed by heat after it has been subjected to a vortex cell. This technical solution is not complicated because it requires no vacuum and is easy to clean.

Steinecker's innovative technology

The Bischofshof brewery chose Steincker's innovative technology not only for the heat treatment of the mash but also for the entire saccharification plant. In addition to the Calypso “vortex boat”, Krones also installed two ShakesBeer mash manufacturing systems, a Pegasus purification pot, a Stromboli in-line digester, and a process control system that controls the overall operation. It is worth mentioning that in the near future, the saccharification plant can complete saccharification 12 times a day and 20,000 liters per day. The inauguration ceremony of the new saccharification room is expected to be on October 27, 2006. The brewery manager Mr. Hermann Goss is very much looking forward to this day's arrival: “Only by cooking this process, we can save energy consumption equivalent to 20 homes per year, and the beer still maintains the best taste.”
