Production system for highly active nattokinase powder

摘要

PROBLEM TO BE SOLVED: To provide a system for producing a highly active nattokinase powder which can be popularized as an edible and can be conveniently used by a method of packaging in a capsule or adding to a food. A highly active nattokinase powder production system includes a liquid fermentation tank 3, a centrifugal equipment 4, an ultrafiltration membrane equipment 5, a freeze-drying equipment 6 and a crushing equipment 7. In the production system of highly active nattokinase powder, the Bacillus subtilis natto strain N and the fermentation raw material are put in the liquid fermentation tank 3, the mixture is cultivated by aeration and stirring, and then the fermented liquid that has been cultivated in the liquid fermentation tank 3 is fermented by the centrifugal equipment 4. Separate into body and supernatant. Subsequently, the supernatant liquid is put into the ultrafiltration membrane equipment 5 to collect and separate the high molecular weight nattokinase substance, and the nattokinase substance is further made into a powder form in the freeze-drying equipment 6 and the pulverization equipment 7.
