Abstract
Abstract A process for the preparation of purified alcohol from fermented mash wherein the steam employed for the dealcoholization of the mash is divided into two partial flows. One of the partial flows is a heat carrier for a preceding column system for the separation and concentration of the head first run products. The other of the partial flows goes to a subsequent rectifying column for conveying the material and for conveying heat. The substances containing the head first run products are removed directly from the mash by means of a degassing column which precedes the separating column. The steam discharged from the degassing column is concentrated in a further column with regard to its head first run product components.
