Clean brewing bin with acid adjusting device used for soy sauce brewing and acid adjusting method thereof

Abstract

The invention relates to a clean brewing bin with a mixing and oxygenating mechanism used for soy sauce brewing. The mixing and oxygenating mechanism comprises a windlass, a pulley, a sling, a hose, and a mixing and oxygenating detection plate; a ring is arranged at the top of the mixing and oxygenating detection plate; the pulley is fixed on a cap of the clean brewing bin; one end of the sling passes through the ring, and is connected to the windlass; the other end of the sling is fixed on the ring; the mixing and oxygenating detection plate comprises an upper cover and a lower cover which are fixed as an integral; a central air tube and a radial jet pipe are arranged in the mixing and oxygenating detection plate; the central air tube is connected to a rotary joint outside the mixing and oxygenating detection plate; the rotary joint is connected with the hose; and the other end of the hose extends outside the bin body, and is connected with an air supply. The invention further relates to an acid adjusting method. The clean brewing bin with the mixing and oxygenating mechanism used for soy sauce brewing has the following beneficial effects: radial mixing, as well as mixing up and down can be simultaneously realized, so that mixing time is shortened and energy waste is reduced; moreover, buffer effects are produced on the lateral aerated stirring by the lifting stirring of the round plate, so that radial stirring and axial stirring are simultaneously performed so as to avoid production of vibration and abnormal sound.

Description

technical field [0001] The invention relates to a soy sauce fermentation device, in particular to a clean brewing cabin for soy sauce brewing and a sour adjustment method thereof, belonging to the technical field of seasoning production. Background technique [0002] The brewing process of soy sauce is a multi-microbial fermentation process, which is usually carried out in a fermentation vessel. In order to ensure a clean environment during the fermentation process and to ensure the growth conditions of the beneficial bacteria added during the fermentation process, we designed a closed fermentation cabin to prevent the intrusion of outside air, infection of miscellaneous bacteria, and affect the fermentation performance and flavor. Purified air (oxygen) is introduced, and at the same time, air flow agitation is realized to ensure that the fermentation process can be carried out smoothly in a purified environment. [0003] During the fermentation process of the fermentation ...

AI Technical Summary

Problems solved by technology

Because the material is affected by gravity, the distribution of concentration and particle size in the cabin is different, it is difficult to obtain relatively real data based on traditional measurement, and it is also impossible to grasp the pH value of the main fermentation location
