Process for the continuous production of beer

Continous process of producing beer

A process is disclosed for preparing an organic acid and/or its salts from a solution obtained through fermentation. In this process, a pure carbohydrate-containing raw material is used. The acid-containing solution prepared by means of fermentation is supplied to a cell separation, and the acid-containing permeate is supplied to a protein precipitation, where it is mixed with a silicon-containing precipitant at temperatures between 2.degree. and 70.degree. C. The solution thus obtained is supplied to a protein separation, and the acid-containing permeate is concentrated and then supplied to a single- or multi-stage crystallization or a granulation.

Process of preparing an organic acid

A process for the gasification of carbonaceous agglomerates in a reactor at a pressure of the range of 5 to 150 bar. The agglomerates are fed into said reactor from a storage zone located above the reactor and form a fixed bed in the reactor, in which they slowly descend when gasified. At least two gasification agents selected from the group consisting of oxygen, air, steam and carbon dioxide are introduced into said reactor through the bottom and rise through said fixed bed. Solid ash or liquid slag is discharged below said fixed bed and a steam-containing product gas is tapped from the reactor above said fixed bed. In order to minimize or prevent the condensation of steam on the agglomerates in the storage zone, the invention provides for a controlled atmosphere almost entirely free of oxygen and steam which is introduced into the storage zone at a pressure approximately equal to the pressure of the product gas.
