Abstract
Abstract Apparatus for continuously fermenting a moist particulate feed and distilling the fermentation product is disclosed in which a pressure-locked auger forces a moist particulate feed from a hopper into a fermentation tank, liquor is removed from the tank and solids are separated therefrom to produce a beer which is distilled in a distillation column. A combustion engine powers the auger and the means for separating solids, and the engine exhaust surrounds an inlet section of said auger to help heat the pressurized feed therein to produce fermentable sugar within the auger, and the auger includes a section passing to the tank in heat exchange relation to the distillation column to provide heat for distillation. The column is a multistage column angled to face the sun and has an upper glass plate to allow solar radiation to enter and penetrate between the foraminous plates of the column.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
Apparatus for continuously fermenting a moist particulate feed and distilling the fermentation product comprising, a hopper for supplying a moist particulate feed containing a component convertible to fermentable sugar, a fermentation tank, pressure-locked auger means for forcing said feed from said hopper into said tank, means to progressively remove liquor from within said tank, means for separating solids from said removed liquor to produce a beer, a distillation column operatively connected to said means for separating solids for distilling said beer, a combustion engine for powering said auger and said means for separating solids, said engine having an exhaust surrounding an inlet section of said auger to help heat said feed and thereby produce fermentable sugar within said auger, and said auger including a section passing from said exhaust to said tank in heat exchange relation to said distillation column to provide heat for distillation.
Claim 2
Dependent Claim
145 words
Apparatus for continuously fermenting a moist particulate feed and distilling the fermentation product comprising, a hopper for supplying a moist particulate feed containing a component convertible to fermentable sugar, a fermentation tank, pressure-locked auger means for forcing said feed from said hopper into said tank, means to progressively remove liquor from within said tank, means for separating solids from said removed liquor to produce a beer, a distillation column operatively connected to said means for separating solids for distilling said beer, a combustion engine for powering said auger and said means for separating solids, said engine having an exhaust surrounding an inlet section of said auger to help heat said feed and thereby produce fermentable sugar within said auger, and said auger including a section passing from said exhaust to said tank in heat exchange relation to said distillation column to provide heat for distillation.
Claim 3
Dependent Claim
43 words
Apparatus as recited in claim 1 further comprising a heat exchanger operatively connected to preheat the beer supplied to said column and to cool spent beer removed from said column, and means to return a portion of said spent beer to said tank.
Claim 4
Dependent Claim
23 words
Apparatus as recited in claim 1 in which said engine also powers a vacuum pump which reduces the pressure in the distillation column.
Claim 5
Dependent Claim
27 words
Apparatus as recited in claim 1 in which said hopper is jacketed, and the exhaust leaving the auger passes through said jacket to preheat said moist feed.
Claim 6
Dependent Claim
17 words
Apparatus as recited in claim 1 in which said means for separating solids is a continuous centrifuge.
Claim 7
Dependent Claim
47 words
Apparatus as recited in claim 1 in which said distillation column is a multistage column angled to face the sun and having an upper glass plate to allow solar radiation to enter the column, said column having foraminous plates positioned to be penetrated by the solar radiation.
Claim 8
Dependent Claim
29 words
Apparatus as recited in claim 1 in which said fermentation tank is jacketed and fan means are provided to blow cooling air through the jacket to cool the tank.
