Disturbing pan

The sturgeon pan was a salt pan that was used for the intensive boiling of brine.

The purpose of the Störpan was to bring the brine to a higher salt concentration by boiling it several times (at least 6 times in 24 hours). In the course of this process, new brine was repeatedly refilled until the salt content was sufficient for the other salt pans, where then the crystallization could take place more slowly and finally. This process has been called disturbance .

The sturgeon pan was arranged higher than the boiling pan so that the brine could easily be passed on. The transfer from one pan to the next was done via a wooden gutter or a copper pipe. In this step, impurities or foam could also be removed with the aid of a protective basket or desired components could be added.

A sturgeon pan often included three boiling or suction pans. The sturgeon pan had dimensions of around 3 by 10 m, with the brine level in it being kept at around 1 m. The filling volume corresponded to 30 m³, for which 180 quintals of raw salt were required as content. The pan was divided into different basins. The pan sheet metal used had a thickness of 2.5 to 3 mm and all connections between the sheet metal parts were riveted.

Later one went over to "disturb" directly in the salt pans.
