Description

Aspergillus sojae culture is with turning over bent device Technical Field The utility model relates to the technical field of fermentation, in particular to a koji turning device for aspergillus sojae culture. Background In the brewing process of soy sauce, aspergillus sojae plays a role of importance. Aspergillus sojae is one of the core microorganisms in soy sauce brewing, has close relationship with Aspergillus oryzae, but has unique advantages in enzyme secretion and flavor formation. The aspergillus sojae is usually mixed with aspergillus oryzae or aspergillus niger according to a certain proportion to participate in the fermentation of soy sauce, the content and quality of the aspergillus sojae play a decisive role in the flavor of soy sauce, and the aspergillus sojae needs to be overturned and radiated frequently in the process of preparing the koji so as to ensure that the aspergillus sojae is in a state of 30 ℃, the growth state of the aspergillus sojae at the temperature is the best, and the flavor of the brewed soy sauce is the best. Besides manual turning, the turning mode adopted in the prior art also uses mechanical equipment to turn the fermentation platform of the aspergillus at regular time, so that the mode can replace the complicated manual turning process to a certain extent, the trouble that the temperature of the aspergillus needs to be paid attention to at any time by manpower can be omitted, but the internal part of the aspergillus is difficult to turn by the direct turning mode, the central temperature of the aspergillus can be still higher, and the fermentation quality is affected. Disclosure of utility model The present utility model has been made to solve the above-mentioned problems, and provides a koji-up apparatus for culturing Aspergillus sojae.
