DE10150395A1 - Beer brewing boiler has a pipe system, with wort plates, where the liquid and solid brewing components are forced through by a pump, without using stirrers or filters - Google Patents

Abstract

The boiler (1) for brewing beer is used for all the brewing stages, using a pipe system (4) where the liquid flows through, without stirrers or filters. The liquid and solid brewing components e.g. water, malt and hops, are flushed through a pipe with wort plates (5) fitted with slits or holes, by a pump (2) resistant to heat. The pipe can be outside the boiler, with thermal insulation.

Description

It is known to brew beer over water, malt and hops Different temperature levels for worting beer can be processed with stirring. The refining process is a very complex thing, especially when it comes to it amounts of household beer (home brewers) (see DE 29 50 7934 U1, DE 195 41 225 C1 u. a.). In known processes, filter bags (see DE 44 40 600 C1, DE 195 03 244 A1), boiler with full-space filter with agitator (DE 195 24 783 C1, WO 98/32836), kettle with 2 lids (WO 98/32836, DE 197 03 076 C1) and Similar techniques (cf. DE 29 51 7521 U1) for separating the solid components applied by the liquid. An agitator is also required (including DE 296 13 939 U1, DE 296 18 738 U1, DE 197 47 050 A1, DE 197 37 007 C1). After that Brewing process is to cool the wort.

The invention mentioned in claim 1 has the advantage that it is no longer necessary to move solid and liquid mash constituents, but only the solid constituents in the hydraulic pipe (see figure 4 , located in the boiler in FIG. 1, in FIG. 2 from the Boiler removed). Only the liquid is moved by means of a pump (see figure number 2 ). This eliminates the need for an agitator. The refining and filtering process is also carried out by removing the tube (figure 4 ) from the boiler (figure 1 ). The filter surface can consist of a flat sheet ( Fig. 1) or a refined sheet surface enlarged with a cone ( Fig. 2, figure 5 ). The sheets in Fig. 2 lead to a faster drainage of the liquid. The tube (figure 4 ) with the spent grain can be easily emptied, rinsed and reused. A transfer into an existing lauter tun is not necessary. If the hydraulic pipe is operated outside the boiler, it must be insulated against heat loss and during the refining process, the liquid must be returned to the boiler in a suitable manner.

The hydraulic pipe process minimizes contact with the ambient air. This reduces contamination problems and minimizes energy losses. The space required for the brewing system is less than with traditional brewing technology. By segmenting the tube or changing the distance between the upper and lower refining plates (figure 6 ), the brewing quantity can be varied as required up to a maximum capacity limit from a minimum that is technically required by the boiler heating ( Fig. 2, figure 3 ). B. for the development of new beers in addition to an optimal brewing quantity, small quantities can also be produced as samples in the same system. With appropriate insulation, the brewing kettle can also be used for fermentation, which usually takes place with cooling. The temperature is controlled by a time-controlled thermostat. The heating can be done by an electric immersion heater or a plate heater (electrical or other suitable energy suppliers). This applies accordingly to the cooling coils or plates ( Fig. 1, Fig. 3 and 9).

The figure shows the principle of the process. The malt or hops (Figure 7 ) are filled in between the refining plates with slots or holes (Figure 5 ). The pipe is placed in the kettle (figure 1 ) with the water heated to the mashing temperature or in the purified pre-wort and fixed. The pump (Figure 2 ) now pumps the liquid with hydraulic pressure through the lower refining plate (Figure 5 ), then through the malt or hops (Figure 7 ), passes the upper refining plate (Figure 5 ) and pours back into the boiler room (figure 1 ). In this way the liquid cycle is closed. After the respective work steps, the tube (figure number 4 ) is removed from the boiler (figure number 1 ) after removal of the cover (figure number 8 ) and cleaned. To drain the liquid in the pipe (figure 4 ), it is fixed by a holding device above the liquid level of the boiler (figure 1 ). The finished wort can now be fermented in the boiler, if necessary with cooling (Figure 3 shows both heating and cooling coils, Figure 9 alternatively or additionally a heating / cooling element in plate form). Depending on the type of beer, the lid (Figure 8 ) can only be put on or fixed in a pressure-stable manner.
