PROCESS FOR THE CONTINUOUS MATURATION OF BEER |
| 摘要 |
<p>For the continuous maturation of beer by further reaction of the wort treated in the primary fermentation step with yeast on a support, open-pore sinter glass having a porosity of 40-65% and pore sizes of 60-300 mu m is used as support for the yeast and the reaction is carried out at elevated pressure, in particular at 2-6 bar. In the fluidised bed reactor, sintered glass supports, in particular sintered glass beads of particle size </= 5 mm (in particular 1-2 mm) and superficial velocities of 20-120 m/h are employed. In the packed bed, Raschig rings of 8-25 mm DIAMETER , in particular, serve as support. The preferred reaction temperatures are 2-15 DEG C and the preferred residence times are 1-15 h, the diacetyl content serving in particular as a control parameter, which should remain </= 0.1 mg/l. In the start-up phase, in particular, yeast concentrate inoculum is allowed to grow at 20-35 DEG C and residence times below the generation time of the yeast over a period of a few days on the porous glass support. <IMAGE></p> |
