This invention relates to a method for mashing starch-rich material, for example whole grain or partially crushed grain, when manufacturing alcohol. The method has a very low energy consumption, because the amount of water added to the starch-rich material in the beginning of the mashing stage is low. High pressure steam and a short processing time are used to keep the starch-rich material to water ratio during the processing stage below 1:2 because very little water is condensed from the water vapor during a short period. The mashed material is finally broken down by "shooting" the material from the reactor by using pressurized air. |
