ABSTRACT:
An apparatus and method for producing alcohol fuel in an efficient and continuous manner are provided. The apparatus and method utilize otherwise lost heat to reduce the amount of heat required to convert feed stock into alcohol fuel. The apparatus and method utilize the supply of feed stock from a hopper through an auger to a cooker vessel, and then in turn to enzyme and fermenting tanks or vessels, which in turn discharge fermented mash to a strainer for separation of the alcohol beer from the mash. The beer is then discharged to a level controlled beer tank which regulates a residue valve controlling the amount of residue liquid returned to the apparatus and maintained under process. From the beer tank, the flow of the beer is regulated by passage through a non-clogging control valve into a reflux column. A single control in the form of a sensible heat detector in the reflux column operates the non-clogging control valve and simultaneously regulates both the quantity of beer supplied to the reflux column and the amount of reflux supplied thereto. The reflux column utilizes highly efficient spreader and concentrator plates therein which are supplied with reflux from the incoming beer to enhance the efficiency of the reflux column. From the reflux column, uncondensed alcohol vapors may be withdrawn and then treated with a denaturing agent before being condensed so that pottable alcohol is never formed. Additionally, heat exchangers are utilized in the apparatus and method to recapture what would otherwise be lost heat, particularly from the hot residue liquid accumulated and discharged from the reflux column, for heating the various fluids in the apparatus and under process.
