A dry grind ethanol production process and system with front end milling method is provided for improving alcohol and/or by-product yields, such as oil and/or protein yields. In one example, the process includes grinding corn kernels into particles then mixing the corn particles with a liquid to produce a slurry including oil, protein, starch, fiber, germ, and grit. Thereafter, the slurry is subjected to a front end milling method, which includes separating the slurry into a solids portion, including fiber, grit, and germ, and a liquid portion, including oil, protein, and starch, then milling the separated solids portion to reduce the size of the germ and grit and release bound starch, oil, and protein from the solids portion. The starch is converted to sugar, and alcohol is produced therefrom then recovered. Also, the fiber can be separated and recovered. Oil and protein may be separated and recovered as well.

An ethanol production facility is provided for processing a plurality of fermentable feedstock materials into an ethanol end product through fermentation and distillation. The facility includes a fermenting stage for converting the plurality of fermentable feedstocks into an alcohol mixture including ethanol and water, and a distillation stage. The distillation stage distills the low concentration alcohol mixture into a high concentration alcohol distillate. A kernel feedstock processing stage is receives and processes a kernel containing feedstock, and includes a receiving station for receiving the kernel containing feedstock. A storage station is provided for storing the kernel based feedstock, and a mill is provided for milling the kernel based feedstock into a flour based feedstock. A conveyor is provided for conveying the milled floor based feedstock to the fermenting stage. A flour feed stock processing stage is operable in parallel with the kernel feedstock processing stage for receiving and processing a flour predominant feedstock. The flour feedstock processing stage includes a storage station for storing the flour for predominant feedstock, and a pneumatic conveyor for conveying the flour to the fermenting stage.

A method and system for efficiently producing a fermentative product alcohol such as butanol utilizing in situ product extraction are provided. The efficiency is obtained through separating undissolved solids after liquefying a given feedstock to create a feedstock and prior to fermentation, for example, through centrifugation. Removal of the undissolved solids avoids problems associated with having the undissolved solids present during in situ production extraction, and thereby increases the efficiency of the alcohol production.

Systems and methods are disclosed for treating lignocellulosic biomass to be supplied to a fermentation system for production of a fermentation product. The systems and methods comprise pre-treating the biomass into pre-treated biomass and separating the pre-treated biomass into a liquid component comprising sugars and a solids component comprising cellulose and lignin. The systems and methods also comprise treating the solids component of the pre-treated biomass into a treated component. The biomass comprises lignocellulosic material. Treating the solids component comprises application of an enzyme formulation and makeup water to form a slurry. The enzyme formulation comprises a cellulase enzyme. The makeup water includes a clarified thin stillage composition and/or an anaerobic membrane digester effluent composition.

This disclosure describes techniques for using a single feedstock of barley to produce a fermented product and a method for filtering a large-particles stream from a liquid stream containing small particles of a process stream using a series of mechanical separation devices to increase yield.

An apparatus for treating a biomass feedstock at a high temperature, includes a cooling device 90 for cooling a biomass treated liquid at a high temperature; an enzymatic saccharification tank 103 for saccharifying a cooled treated liquid 101B with an enzyme; a solid-liquid separation apparatus 112 for removing water-slightly soluble substances contained in a saccharide solution 104 taken out from the enzymatic saccharification tank 103 and a foreign substance removing unit 113 provided with a microfiltration (MF) membrane 113a; a dilution tank 132, disposed downstream of the foreign substance removing unit 113, for diluting the saccharide solution from which the water-slightly soluble substances are removed by adding water thereto; a water separation unit 116, provided with a reverse osmosis (RO) membrane 116a, for removing water 114 from the diluted saccharide solution so as to obtain concentrated saccharide solution 115.

Improved methods for anaerobic digestion of organic matter to produce biogas. Among the improvements given are including ferric iron in a hydrolysis reactor to increase the rate and efficiency of anaerobic hydrolysis to provide substrates for methanogenesis. A solids separation step is added after hydrolysis and before methanogenesis to improve the efficiency of the methanogenesis step. Other improvements involve using separate tanks for the hydrolysis and methanogenesis stages and using two (or more) methanogenesis tanks in sequence, and switching the order of the two (or more) methanogenesis tanks periodically.
