Definitions

  • the invention relates to an apparatus and a method for filtering beer.
  • the beer is filtered to remove yeast from the beer.
  • the membrane filtration of beer has been an increasingly accepted technology for several years.
  • the crossflow method is used, in which the unfiltered beer, i. the unfiltrate is circulated through the membrane filter and the filtrate is withdrawn from the membrane filter. The unfiltrate is thereby flowed along the membrane, wherein the filtrate emerges perpendicular thereto.
  • plastic hollow fibers or ceramic filter cartridges with microfiltration pores are used as membrane.
  • the unfiltrate side (retentate side) inevitably concentrates on this. This means that the yeast concentration and the concentration of the other retained components (mixture of different proteins, bitter substances and polysaccharides, etc.) increases over time in the unfiltered cycle.
  • the problem with the known filtration methods is that during the course of the filtration, the unfiltrate is concentrated to such an extent, and in the course of filtration there is a limit at which the filtration must be stopped and the concentrate must be disposed of. Furthermore, the membrane locks after a certain time so strong that a cleaning is inevitably necessary. To control the filtration of the transmembrane pressure is usually observed and then stopped at predetermined limits, the filtration, expelled the unfiltered or diluted concentrated filtrate with fresh unfiltered.
  • the present invention has the object to provide a device and a method for filtering beer, which allow to extend the life of a membrane filter in a simple manner.
  • the device according to the invention for filtering beer comprises a membrane filter through which unfiltered material can be circulated and filtrate can be diverted. Furthermore, at least one sensor in the unfiltered stream is provided for measuring a parameter which depends on the yeast concentration in the unfiltrate or retentate. Next, a control / regulating device is provided for controlling / regulating process parameters of the filtering process as a function of the measured parameter. The fact that the sensors are arranged in situ, no sample must be removed, so that a continuous measurement is possible.
  • the process can be controlled or regulated as a function of the yeast concentration in the unfiltered. Since the sensor is thus arranged in situ in the unfiltered stream, the yeast concentration in the lines of the device can be monitored and suitable measures can be taken if the concentration is too high. Thus, the measures can already be taken before it comes to clogging of the membrane. Therefore, the service life of the membrane filter can be significantly increased. In addition, the filtration end, i. when, e.g. a cleaning must take place, be accurately determined and no inaccurate estimation using a concentration factor is necessary.
  • the at least one sensor is advantageously provided in situ in the non-filtrate circuit and / or in a return to a concentration tank. It is advantageous if the sensor is arranged in the unfiltered circulation, since the concentration of the unfiltered material can be constantly monitored here. In the arrangement in the return or the return line is advantageous that the sensor can be made smaller and thus cheaper than a sensor which is arranged in Unfiltratniklauf, because here is the same concentration as in circulation.
  • the senor is a viscosity sensor and / or density sensor, i. that the parameter measured is the viscosity of the unfiltered or the density of the unfiltered. If both sizes are measured, a combined sensor can be used as well as two sensors.
  • a sensor is used to measure the viscoelasticity.
  • the control / regulating device is designed such that a filtration end can be determined as a function of the measured parameter. This means that the device is stopped depending on the yeast concentration. It is also possible that the yeast concentration in the unfiltered or retentate is adjusted as a function of the measured parameter. For example, if it is determined that the yeast concentration or parameter is too high, the concentration may be reduced by, for example, discharging unfiltrate from the non-filtrate cycle, for example, to a tank or channel. The circulating non-filtrate is then fed to the device with fresh unfiltrate is diluted and thus has a lower concentration, so that the device can continue to operate without the filtering process must be stopped.
  • the overall filter life can be increased and the overall filtration performance can be increased (ie, the filtration performance can be kept consistently high and performance degradation can be prevented), delaying clogging and associated cleaning process , Thus, the service life of the filter can be increased.
  • the control or regulating system can have a fuzzy logic or an artificially neural network.
  • the measured data can be supplied to a software sensor and closed by means of fuzzy system or artificial neural network on the yeast concentration.
  • the advantage of additionally measuring the turbidity and including this parameter is that a haze measurement in beer filtration already exists in most cases or is almost always part of the beer filtration system and thus one can resort to an already existing technology. Since the turbidity measurement is usually based on the light radiation (transmitted light, scattered light), it may be that with high numbers of yeast cells, the refraction of light is no longer sufficient and thus leads to incorrect measurement results. This is the case in particular with a cell number from 10 8 cells / ml.
  • the advantage of viscosity measurement too recognize, because the measurement of viscosity shows meaningful measurement results especially at high cell count concentrations. As can be seen from FIG.
  • the viscosity increases significantly at approximately 10.sup.8 cells / ml (which corresponds approximately to the value of 100 on the x-axis), thus the viscosity indicates measurement results which can be used exactly in the range at which the turbidity measurement, due to inaccuracy or measuring limit of the turbidity measurement, can no longer be used.
  • the measuring range of the viscosity should be in a range of 0.002 to 1.5 Pas (at 0 ° C.), thus ensuring that the method / device according to the invention can be realized.
  • the controller may use either the measured parameter of the turbidity measuring sensor or the viscosity measurement or density measurement or viscoelasticity measurement parameter to control process parameters.
  • the measured values of the sensor are used for viscosity measurement (or density measurement or viscoelasticity measurement) and for a cell count or a corresponding measured value, which is less than a limit value (in particular ⁇ 10 8 cells / ml), the measured values of the sensor are used to measure turbidity.
  • unfiltrate is filtered, wherein the unfiltered material is circulated through a membrane filter and filtrate is discharged from the membrane filter, a parameter in the unfiltered stream, which depends on the yeast concentration in the unfiltrate, while the filtration is measured and process parameters of the filtering process depending on measured parameter can be controlled or regulated.
  • the parameter can be measured continuously in situ during the filtration process.
  • a changing yeast concentration which, for example, is above a limit value.
  • the concentration may e.g. no higher than a certain value (for example about 17-18% dry matter) without significantly affecting the performance of the filter.
  • the parameters can be measured in the unfiltrate cycle and / or in the return to a concentration tank.
  • the density and / or the viscosity can be measured as a parameter.
  • the use of density and / or viscosity to determine the concentration of the unfiltrate is a particularly skillful and simple means of monitoring the filtering process.
  • the measurement of the viscoelasticity is also suitable.
  • the yeast concentration can be adjusted in the unfiltered, in particular unfiltrate can be removed from the circulation, e.g. in a concentration tank or channel or buffer tank.
  • the end of the filtration process can be determined as a function of the measured parameter.

  • the pore size for beer filtration is in particular in a range from 0.1 to 1 ⁇ m, in particular 0.4-0.6 ⁇ m.
  • the device has a feed line 3, via which beer loaded with yeast is pumped in the direction of membrane filter 1, for example via a pump 7 becomes.
  • the device comprises a circulation line 5, into which the feed line 3 opens and through which the unfiltrate, i. the retentate, can circulate in the circulation K.
  • the device further has a return line 6, can be derived via the unfiltered from the circulation line 5.
  • a control valve 9 is provided, via which the flow of the discharged unfiltered material can be adjusted.
  • a drain line 12 branches off from the return line 6, via which the non-filtrate from the return line 6 can be supplied to the channel 10 via a control valve 1 1. Via the valve 1 1, the flow of the unfiltered can be adjusted.
  • the return line 6 opens into a concentration tank 2, here e.g. is designed as a cylindroconical tank and which is connected via a line 13 and a control valve 14 to the supply line 3.
  • concentrated unfiltered material from the concentration tank 2 can be supplied to the feed line 3 again.
  • the beer filtering device comprises at least one sensor 4a, 4b in the unfiltered stream, i. on the retentate side, to measure a parameter that depends on the yeast concentration in the unfiltrate.

  • the sensor 4a is located in front of the filter 1.
  • a corresponding sensor 4b may also be arranged in the return line 6, as likewise shown in FIG. 1, here preferably in the flow direction downstream of the valve 9.

  • Particularly suitable sensors are a viscosity sensor and / or density sensor. As can be seen in particular from Fig. 3, there is a relationship between the viscosity and the yeast concentration, i. the yeast cell count / ml. As the yeast cell count HZZ increases, the viscosity ⁇ of the unfiltered material increases at a certain temperature.
  • Fig. 6 shows, for example, the viscosity as a function of the cell number at 0 ° C of a sample. Thus, it is easy to deduce the cell number and thus the concentration by measuring the viscosity.
