    1536086 Sampling and testing beer GROUPEMENT D'INTERET ECONOMIQUE TEPRAL 1 Nov 1977 [2 Feb 1977] 45388/77 Heading G1B [Also in Division F2] Small volume samples from fermenting beer in vats 7, 7a, 7b are withdrawn automatically from at least three points 3, 4, 5 &c. over the height of a vat, the sample points being connected into main conduit 1, which is normally filled with water. The withdrawn sample is cooled in heat exchanger 10 to reduce the temperature to from 0‹ to 5‹C, optionally the suspended cells are sampled in by-pass conduit 14, the conductivity of the whole sample is measured at 19 to ensure that there is no foam present, pH, dissolved oxygen and temperature are measured and the sample passes through fluid throttling device 20 which operates to substantially suppress froth formation by minimizing abrupt pressure changes.

    FIG. 1 shows a scheme for carrying out the device without chromatographic measurement in the gas phase; in fig. 2 - the same, with chromatographic measurement in the gas phase; in fig. 3 is a schematic diagram of a device for throttling a fluid, longitudinal section.
    The device contains a main kandl 1, which has at its upper end a supply of water through the solenoid valve 2, and several channels are mounted on this main channel for sampling, for example, three channels 3-5 through electrovalves b with three ways for sampling at the height of the fermentation tank 7
    The main channel through the solenoid valve 8 is connected to the coil 9 of the heat exchanger 10 of the refrigeration unit 11, the latter is connected to the measuring cell 12 via an overflow pipe 13 with a valve 14 installed on it for sampling and determining the particles in suspension.
    In the device without chromatographic measurement, in the gas phase, measuring elements are installed in the measuring cell, which are isolated by valves 15 and installed in parallel; recording devices 16-19 are used as measuring elements for measuring dissolved oxygen, telesheratura and liquid conductivity.
    Valves 15 provide adequate isolation of the measuring elements. At the outlet of the measuring cell there is a device for throttling a fluid with an adjustable flow area, consisting of two cylindrical elements 20 and 21, connected by an overlap, inside which is located a piston 22, having an oval shape in longitudinal section, the cross-sectional area in the section of cylindrical elements exceeds the cross-sectional area of its inlet and outlet sections of the throttling device, while the piston 22 has a threadedly drilled hole 23 and a gear a piston wheel 24 for moving. A device for throttling through the solenoid valve 25 is connected to a collector 26 supplying a switchgear 27 for draining water to drains 28, and beer samples to a hopper
    boiler 29 for recirculation of this pi, w ...
    The device is also equipped with a multichannel automaton that serves to control a series of sampling for
    0 ONE, fermentation tank, and contains a program block 30 and a chain 31 of the control of receiving and transmitting zgmers from the respective sensors.

    5 volatile substances. At each stage of the measurement, it is possible to increase the amount of the sample taken to a strict minimum value, which he passed using water. Prior to the new measurement sequence, the entire device for implementing the method is skimming, and at the end of the cycle, the water flows the motive and wash water and recovers the sampling of beer after treatment in the hopper kettle. The device works as follows. The circuit is filled with water, and the fluid choke device located at the end of the circuit is closed at the beginning of the sequence. When a selection signal is given. Samples, the fermentation tank is brought into contact with the circuit through an open solenoid valve and the device opens. The beer gradually fills the chain, pushing the doo. The conductivity sensor located at the end of the chain detects the moment when the chain is filled with beer, as well as the possible formation of pans, and transmits this information to the multi-channel automaton, the latter generates a signal and closing the electrovalve, thereby bringing the system into contact with the winding tank. In order to reduce the displayed amount, the beer is pushed into the water, which occupies the main pipeline of the passage during the measurements. Next is the stage of washing and refilling with water. In order to ensure the visibility of the sample, a certain amount of beer is taken out before making measurements. For this purpose, the throttling device is closed and the beer is in the chain for as long as it takes to make various measurements. The chain is then washed with water. As a result, the re-use of this method and device reduces the loss of beer due to the fact that there is no need for periodic analyzes, as well as the return of the beer used in the measurement, and again it can be used in the production process. Claim 1.
