Products after their sterilization.

Patented in the German Empire on April 22nd, 1899.

When the beer is pasteurized (see e.g. the English patent specification 9923 of the year 1896 and Swiss patent specification 9683) the gaseous components are extracted from the liquid driven out and collect with a voltage corresponding to the heating in the upper part of the pasteurizer vessel, which thereby, if the vessel space is economical should be exploited, so much in terms of strength and sealing It is assumed that the implementation of this process is very difficult with larger quantities of beer. As is well known there are many breaks even when pasteurizing in bottles. The complete derivation the escaping gases would adversely affect the beer. The simple derivation and recycling of the separated, gaseous components into the cooled one Beer would call the success of the whole process into question, given the gas elimination Immediately after initiation of the heating of the beer begins and here yeast and other microorganisms contained in the beer be taken which have not yet been killed or at least not weakened enough to prevent any further fermentation to stop.

The present process is intended to allow the beer to be pasteurized in larger quantities by that the gases and vapors separated by the heating of the beer are discharged from the pasteurizer outside of it sterilized, and then in a second vessel. which is already cooled, its gaseous Contains constituents of deprived, pasteurized beer for the purpose of impregnation of the latter be guided.

The discharged gases can be sterilized in various ways. The gases can z. B. to kill the germs entrained by a sufficiently highly heated point (a, steam chamber, open fire, etc.) are conducted; but they could also get through through a filter and freed from fermentation-causing germs.

In the accompanying drawing, a device is shown schematically, which the Allow pasteurization of the beer according to the present process in uninterrupted operations target.

The device consists of the two beer vessels α and b with the inlets c and d and the outlets e and f. The two beer vessels are connected to one another by pipes gh and the pipe coil z, which is located in the steam box k. The steam passes through the pipe / into the boiler k and the condensate is drained off through the tap m .

The vessels α and b are in the for receiving heifsem respectively. cold water certain vessels η and 0. The water is fed to the latter through ρ and q and drained through r and s.

If beer is to be pasteurized in uninterrupted operations, the vessel α , for example, is filled with beer up to the top wing

of the agitator f is filled and then hot water is passed into the vessel η . So that the beer in the vessel α more quickly reaches the degree of heat required to kill the germs, it is moved in a known manner by the agitator t .

The vapors and gases escaping through gi and h into the vessel b can initially be discharged through f and be lost, the gases passing through the snakes i being sterilized.

If the beer in the vessel α has been heated sufficiently long and sufficiently high, the vessel b is filled with fresh beer and pasteurized in the same way as was previously described. The gases escaping in the process get into the vessel a, which is now cooled with cold water flowing through the vessel η for the purpose of cooling its contents. The gases and vapors escaping from b condense in the vessel α uricl recombine with the beer, which can be accelerated by moving the beer appropriately by means of a stirrer.

If the beer in the vessel b has been heated for a long enough time, the beer in the vessel α is cooled down sufficiently in the meantime, and it is enriched again with gaseous constituents. The pasteurized beer can then be drained from the vessel α and used further. The vessel a is then recently filled with fresh beer and pasteurized, the gases and vapors escaping from α being diverted to b.

The movement of the gases and vapors escaping from the warmed beer can through suitable devices, e.g. B. by a switched on in the pipeline impeller promoted and be regulated.

Claims (1)

Patent claim: Process for pasteurizing beer in large quantities, characterized in that that the gaseous constituents of the separating during the heating Beer derived from the pasteurizer, sterilized outside and in a Another pasteurizer, which has already been cooled, pasteurized, and in the same way contains degassed beer, are passed for the purpose of impregnation of the same.
