Malted Grain Fraction Separation with Low-Moisture Husk Recovery

The patent replaces chemical treatment methods (acid hydrolysis) with a mechanical separation system consisting of a grinder, centrifuge, and filter. This mechanical system achieves component separation through physical means rather than chemical reactions, thereby reducing process complexity and energy consumption while maintaining separation efficiency.

The patent extracts and removes specific components (starch, protein, fiber) from the BSG mixture through mechanical means. The grinder breaks down the grain structure, the centrifuge separates components based on density, and the filter removes residual particles, achieving component extraction without requiring chemical treatments.

The patent substitutes chemical energy input (acid hydrolysis) with mechanical energy input (grinding, centrifugation, filtration). This mechanical approach achieves component recovery with lower energy consumption as it avoids the high energy requirements of chemical treatments and subsequent neutralization processes.

The patent employs a self-service separation system where the mechanical energy input is sufficient to achieve complete separation without requiring additional chemical agents. The system uses the inherent physical properties of the components (density, particle size) to achieve separation through mechanical means alone.

The patent segments the BSG processing into distinct functional stages: grinding (breakdown), centrifugation (separation), and filtration (purification). This segmentation allows each component to be optimized for its specific function, achieving high fraction recovery efficiency while keeping the overall process relatively simple through modular design.

The patent implements a continuous processing system where BSG is continuously fed into the grinder, which continuously produces a paste that is continuously fed to the centrifuge and then to the filter. This continuous operation maintains high fraction recovery efficiency and reduces moisture content without requiring complex batch processing steps.

The patent designs each piece of equipment to perform multiple functions: the grinder not only breaks down the grain structure but also pre-mixes components; the centrifuge separates multiple components simultaneously based on density; the filter removes both large particles and residual fine particles. This multi-functionality achieves high separation quality with a minimal number of equipment pieces.

The patent merges the separation functions into a single integrated workflow where the output of one stage becomes the input of the next without requiring intermediate storage or additional equipment. The grinder output directly feeds the centrifuge, which directly feeds the filter, creating a merged processing stream that achieves high separation quality without increasing device complexity.
