ABSTRACT:
An improved boiler that allows distillation of ethanol from a continuous flow of a hydrous feedstock compound, which may be beer or other semi-solid substance. The internal compartment of the boiler is separated into different zones by a plurality of primary baffle plates and secondary baffle plates. The hydrous feedstock compound is heated as it passes from one zone to another zone and ethanol inside the hydrous feedstock compound vaporizes. The ethanol rich vapor is channeled through a collector column and then collected for further processing. The temperature of the hydrous feedstock compound is slightly different from one zone to another zone because of ethanol concentration changes as the hydrous feedstock compound moves from one zone to another. At the last zone, where most of ethanol is removed, the remaining hydrous feedstock compound is removed from the boiler.
