The group of inventions relates to the food industry, namely, to a method and device for processing brewer's spent grains. The invention makes it possible to obtain a gluten-free protein drink with a protein content of at least 10.0 wt. % dry weight. The principle of the invention is based on the technology of preparing brewer's spent grains for the extraction of nutrients and their extraction by mechanical processing on the proposed industrial line. The essence of the method lies in the fact that brewer's spent grains are loosened on a vibrating screen, crushed in a colloid mill, with the addition of water in a ratio of 0.5:1 to 1:1 with respect to the grains, to obtain a paste-like homogeneous mass, and then this mass is processed in a screw extractor for further grinding and separation into 2 fractions, namely: a suspension with a water content of 90-95%, which all nutrients remain in, including the proteins of the brewer's spent grains, and crushed husks of the brewer's spent grains with a water content of 60-75% suitable for further industrial use. Then, the suspension is subjected to removing suspended particles to obtain the final product—vegetable milk (protein drink), which is pumped into a storage tank.

This novel corn milling process includes a continuous steeping step, early separation of easy-to-access starch (e.g., starch in the floury endosperm part of a corn kernel), fine milling to secure germ protein without the use of solvents or heat, and performing a phase separation to collect the product of fermentation. The continuous steeping process uses a continuous steeping tank. The steeping liquid, which includes probiotics, flows in from the bottom of the tank in a countercurrent flow. Other features include efficiently producing high purity starch or sugar using the starch in the floury endosperm of the corn kernel, producing alcohols such as ethanol and butanol that can be used as sustainable aviation fuel or feedstock for sustainable aviation fuel, and producing a high protein animal feed product that includes yeast and germ protein without using toxic solvents.

A process for converting spent grain into flour by drying and milling is disclosed. The process includes the steps of introducing a quantity of wet spent grain into a container for removing moisture by the action of gravity. After the gravity drying, the wet spent grain is transferred to a press to mechanically remove additional moisture. The wet spent grain is placed in a fluid bed processor where the grain additional moisture is removed through heating and fluidization. Some embodiments may include a dust collection system in connection with the fluid bed processor, wherein the dust collection system incorporates a separator for separating the grains. Once dried, the dry spent grain is introduced into a mill to be ground into the proper flour consistency. The resulting flour product can then be used for a variety of foodstuff applications.
