Abstract: This invention relates to a process for the automatic representative taking of samples of fermented beverages. The method consists in taking samples at several different points in height of the fermentation tank, cooling them and proceeding with a determination of the cells in suspension, measuring the hydrogen potential, the dissolved oxygen, the temperature, and the conductivity, carrying out a chromatographic analysis of the volatile and other matters in accordance with a sequence which depends on the state of advance of the fermentation, and is carried out by an automatic device. The installation is characterized by the fact that it comprises a principal conduit having a water inlet at its end and to which there are connected various sampling conduits, it continues into the exchanger of a refrigerating group and is connected to a measurement unit which has a fluid wiredrawing device at its end. The invention applies to the fermented liquid fermentation industry.

Abstract: Beer fermentation apparatus comprises a main pipe for transporting a water-entrained mixture of wort, yeast and gas to a fermentation tank. A measuring device is mounted in a by-pass circuit of the main pipe for measuring the amount of gas dissolved in the water, the device comprising a vertically disposed measuring chamber having an inlet at its lower end and an outlet at its upper end which are connected to upstream and downstream portions of the main pipe for flowing the mixture through the measuring chamber. The chamber inlet is located a sufficient distance above the lowermost end of the chamber so as to effect formation of a relatively stagnant flow region which is substantially free of gas bubbles in the measuring chamber beneath the level of the inlet during flow of the water-entrained mixture through the measuring chamber.
