The invention is related to the food industry. The proposed apparatus is used for wort production from grain raw material, and comprises a lower tier, an upper tier and at least one process tier located in-between. Each tier is equipped with a mixer, a water supply pipe, a wort transfer pipe and an auger separator, comprising a perforated pipe or a slotted screen with an auger, squeezed grain raw material outlets, a wort discharge branch pipe, a thrust washer and a thrust spring inside. The bottom of each tier is inclined. A funnel for crushed grain raw material supply is provided on the process tier located above the lower tier. A wort outlet is provided in the lower tier. A method for producing wort from grain raw material is also disclosed. The group of inventions provides an increase in the yield of the finished product.

A method, and related apparatus, for producing beer from any types of grains includes activating phenomena of controlled hydro-dynamic cavitation during all the steps of the process, from mashing to hopping, and possibly after yeast inoculation. The present method and apparatus provide a number of advantages over traditional techniques, for example, avoiding the pre-crushing of the malts or the grains, thereby increasing the efficiency of saccharification and of starch extraction, and avoiding the boiling at equal efficiency of the hopping. Another advantage is the opportunity of causing the concentration of gluten to fall in the final product simply with controlled hydraulic processes through electromechanics, and of possibly extending fermentation.
