Abstract: An automatic apparatus for measurement of the number of cells or particles in suspension in a liquid medium during fermentation, comprising a preparation unit for the measurement, a measurement receptacle mounted for vertical translation, a device for drawing in the liquid to be measured which is provided with oleopneumatic regulation, electronic circuits and measuring, processing and visualizing members wherein, the active members being connected for their operation to a pneumatic automatic device assuring the completely automatic operation of the assembly.

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.
