METHOD AND APPARATUS FOR PROCESSING VINASSE

摘要

The invention is related to a method for processing vinasse that is liberated during the preparation of alcohol from melasse and sugar cane sap and that until now was a useless waste product, in which this vinasse not only is used in a useful manner but moreover leads to an important saving of energy in the alcohol process, characterized in that this is obtained by the fact that the vinasse is liberated during the production of alcohol of which vinasse the dry solids content is 2 to 10%, is concentrated to a dry solids content of about 60%, this concentrated vinasse is burned with an excess of air by spraying in a steam boiler, the steam developed therein being partly supplied to the apparatus for the concentration of the vinasse and for the rest is used in the alcohol preparation process producing the vinasse. With this method a remarkable saving in energy is obtained. The invention also is related to an apparatus for performing said method.
