APPARATUS FOR PRODUCING A MIXTURE OF ETHANOL AND WATER

摘要

The invention relates to an apparatus for a method for producing ethanol. The apparatus comprises a fermentor (6) for receiving fermentable raw material (2), forming a fermentation mixture (8) and feeding a stream of fermentation mixture (8) from the fermentor (6). The apparatus comprises a separator (9) for separating a stream of fermenter beer (10) from said stream of fermentation mixture (8). The apparatus comprises a first evapor ator (13) for evaporating said stream of fermenter beer (10) and separating a stream of mixture of ethanol and water (14). The apparatus comprises a concentrator (17) for concentrating said stream of mixture of ethanol and water (14) to a stream of concentrated mixture of ethanol and water (18). The apparatus comprises a first storage tank (20) for receiving and storing said stream of concentrated mixture of ethanol and water (18). The apparatus comprises a process unit module (21 to 30).
