Definitions

  • the invention relates to systems for the production of beer, as in
  • the liquid intermediates in the beer preparation process contain raw material particles that cloud these intermediates. These raw material particles are washed out of the raw materials used during mashing. However, the finished beer may contain essentially no or only very few or very small raw material particles, since the beer must be filled essentially without clouding. The raw material particles must therefore be separated from the intermediate products.
  • the lauter tun forms a grain layer when the wort is removed from the bottom of the lauter tun by sedimentation of raw material particles, which has the desired filter effect from a certain thickness. Since the grain layer must first form at the beginning of the purification, it is normally necessary to pump the wort in a circle after the lauter tun has been filled. This pump-back process is continued until the spent layer shows a sufficient filter effect and thus the wort drawn off has a turbidity below a defined level. Only then will the wort be passed on for further processing.
  • the object of the present invention is therefore to create a plant for the production of beer, which makes it possible to separate raw material particles from the intermediate products of beer preparation, regardless of the refining process.
  • a separating device is provided in the plant, through which intermediate products can be passed at least in part. At least some of the raw material particles are separated from the intermediate product in the separating device.
  • the separation can be applied to all intermediate products that arise during the beer preparation process, whereby a high degree of flexibility is achieved.
  • the consideration in production control of specific requirements regarding the refining process can be severely restricted.
  • the performance of brewery plants can be increased thereby, and the separation devices according to the invention can also be retrofitted in existing plants.
  • any food technology can be in the separator permissible methods for separating solids from a liquid phase. It is particularly preferable to use a filter and / or a sieve and / or a cyclonic separating element and / or a similar separating module for separating the raw material particles in the separating device.
  • the selectivity of the separating device can be adjusted by selecting one or more identical or different separating modules.
  • the separating device can be used to clarify all intermediate products that arise during the beer preparation process.
  • the separating device can in particular also be connected to a mash filter, a whirlpool, a chamber filter press, a membrane filter, a lauter tun or to several of these system components. Intermediate products that are manufactured in these parts of the plant can thus be at least partially freed of the raw material particles contained.
  • the separating device according to the invention is of particular importance when used in connection with the refining process in the lauter tun.
  • the main goal is to accelerate the refining process.
  • a lauter tun can be used for this purpose, which has an upper-layer wort extraction device in the area above the spent cake and a lower-layer wort removal device in the area below the spent cake, by means of which wort can be withdrawn from the lauter tun. Since the wort that is drawn off in the area above the spent cake is not filtered through the spent layer in the conventional manner, the wort can be removed very quickly here, but must be cleaned separately. This takes place in the downstream separating device, in which raw material particles contained in the wort are separated.
  • the extraction performance from the bottom of the lauter tun is particularly affected by the viscosity of the wort.
  • the wort can be removed from the top layer of wort immediately, the wort removed here being filtered in the downstream filter system.
  • the filtered wort thus obtained can be processed immediately. A standstill of the effective wort removal during the pumping back of the wort until a filter bed is formed at the bottom of the
  • wort can also be drawn off in a conventional manner from the bottom-layer wort extract, whereby the filtering spent layer is formed.
  • the wort is drawn off from the lauter tun via two parallel wort lines, wort being drawn off in the conventional main wort line, which is filtered by the filter effect of the spent grain cake, and wort being drawn off in the secondary wort line, which can be filtered by using the separating device.
  • wort from the lower-layer wort extractor can also be passed over the separating device in order to achieve post-filtering.
  • the wort from the top-layer and bottom-layer wort extraction can be collected in a line and passed together through the separating device.
  • top-layer wort extractor in conjunction with the separating device according to the invention is advantageous not only for avoiding the standstill of the effective wort extractor during pumping back, but also during the subsequent refining process.
  • the wort extraction on the bottom of the lauter tun creates a differential pressure between the area above and below the grain layer. If this differential pressure exceeds a predefined maximum limit, the refining process must be interrupted and the spent cake loosened with the chopper become. The more wort is drawn off at the bottom of the lauter tun, the more the differential pressure increases.
  • a pump-back process is usually carried out in conventional lauter tuns for quality reasons until the spent cake again has a sufficient filter effect. Only then can wort be drawn out of the lauter tun again and passed on for further processing.
  • the top-layer wort extractor in conjunction with the separating device according to the invention, production downtimes during these pump-back processes after a deep cut can be avoided in exactly the same way as when the refining process is started up as described above. While the fore wort is pumped back from the lower-layer wort extractor until the grain layer is restored, wort can be withdrawn from the upper-layer wort extractor, which is filtered in the separating device.
  • the throughput of the lauter tun is greatly increased by using the top-layer wort extractor with a downstream separator.
  • the top-layer wort extract can be arranged at any location of the lauter tun that is located in the area above the grain layer that forms.
  • the main seasoning line and the secondary seasoning line should be preferred be connected to each other with the downstream separating device via a line system.
  • Switchable valves are to be arranged in the lines so that individual line sections can be shut off.
  • both seasoning lines can be connected to one another and the various liquid flows can be converted and mixed into one another by opening and closing individual valves. In this way, the entire liquid flow can be passed through the separating device or the entire liquid flow can be drawn off in the separating device without filtering. Any intermediate states can be set by infeed of the valves, thereby changing the turbidity of the wort as desired.
  • one or more separation modules can be used in the separation device. If several separating modules are installed in the separating device, which are directly or indirectly connected to the inlet and outlet of the separating device via lines, switchable valves are to be arranged in the lines. In this way, individual separation modules or groups of separation modules can be activated separately. By opening or closing the valves, the filter characteristic of the separating device can then be changed by switching individual separating modules or separating module groups on or off.
  • the wort can flow through at least two parallel separation modules in the separation device.
  • the parallel connection of several separation modules allows the throughput of the separation device to be increased without lowering the degree of filtering.
  • separation modules with different separation properties in the separation device. For example, coarse materials can first be separated in coarse filters and subsequent fine filters are not unnecessarily loaded with coarse particles. It is therefore particularly preferable to arrange separation modules with increasing separation capacity one after the other. This measure considerably minimizes the number of cleaning cycles required to regenerate the separation modules, since the filtering spectrum of the individual separation modules is optimally used in each case.
  • a device for measuring the wort turbidity should be arranged after the separating device.
  • the turbidity values measured here can be evaluated by a controller and the data obtained thereby can be used, among other things, to regulate the separation device.

  • the lauter tun 1 shown in FIG. 1 is loaded with raw material from above, as a result of which the liquid column 3 builds up above the bottom 2 of the lauter tun.
  • the wort can be drawn off downwards in a conventional manner via the lauter tube 4 and the main seasoning line 5 connected to it.
  • the grain layer 6 is formed above the bottom 2 of the lauter tun.
  • the through openings 8 are incorporated, through which the wort can be drawn from the region above the spent grain layer 6 from the lauter tun.
  • the wort from this top-layer wort extractor 8 can be pumped into the separating device 12 by means of the refining pump 11 if the valves 9 and 10 are in the appropriate position.
  • the two filters 13 and 14 are connected in parallel and filter out raw material particles from the wort.
  • the filter characteristics of the filter system 12 can be changed by opening and closing the valves 15 within the filter system.
  • the wort can be passed from the two wort extraction devices via the separating device or bypassed the separating device via lines connected in parallel.
