ABSTRACT:
Ethanol (C.sub.2 H.sub.5 OH) is produced efficiently by employing a drive-through pit in which carbohydrate-containing material is fermented by hydrolyzing agents such as enzymes. The configuration and depth of the pit are such as to permit conventional farm vehicles to have ready access to the pit, thereby enabling the pit to be loaded and unloaded conveniently. The pit is insulated on its sides and bottom and is closed at the top by a heat-insulating cover. The pit is heated to assist the fermentation process. After several days of heating, the pit is drained through a sediment trap and the filtered pit drainage is separated into concentrated ethanol and a mixture of water and enzymes. The solid residue left in the pit is removed for use as feed or fertilizer. The separated water and hydrolyzing agents are stored in a reservoir for subsequent flooding of the pit when a new quantity of carbohydrate-containing material is added to the pit.
