Description

Equipment is pickled to pickled peppers Technical Field The invention relates to food production equipment, in particular to pickled pepper pickling equipment. Background The pickled pepper is a traditional seasoning food prepared by taking the pepper as a main raw material and fermenting the pepper by microorganisms, and is popular due to the unique flavor. In the large-scale production, in order to realize resource conservation and environmental protection, the recovery and reutilization of the fermented brine becomes a common practice in the industry, and has important economic and environmental protection values. However, in the process of recycling the brine, a technical bottleneck exists for a long time, namely, as the cycle times are increased, small molecular bad flavor substances such as higher alcohols, aldehydes and the like accumulated in the fermentation process are difficult to remove, so that the problems of flavor degradation, unstable quality and the like of subsequent batches of products are caused, and the long-term effective recycling of the brine and the standardized production of the products are severely restricted. The prior art focuses on physical clarification and conventional component adjustment of brine, such as removal of suspended impurities by flocculation, plate and frame filtration and the like, but has a very small targeted removal effect on poorly soluble flavor substances, cannot fundamentally block flavor degradation chains, and generally relies on 'old brine' with unstable states as a fermentation starting source, so that batch controllability is poor. In addition, in the prior art, when brine recovery and fermentation restarting are treated, brine purification and flora inoculation are generally regarded as two links of cutting, and systematic equipment capable of integrating brine fine regeneration and flora standardization transplantation is lacked. At present, the technical scheme disclosed in the prior art can not be used in an equipment system, and can simultaneously realize molecular-level selective filtration of brine and stable propagation and accurate addition of compound microorganism flora, which also becomes a key equipment bottleneck for restricting the pickled pepper industry to realize high-quality, standardized and continuous production. Disclosure of Invention The invention aims to overcome the above-mentioned background technical difficulties and provide a pickled pepper pickling device for brine recovery treatment and flavor brine regeneration. The technical scheme is that the pickled pepper pickling equipment comprises a fermentation tank, wherein the fermentation tank is connected with a brine recovery tank and a propagation expansion tank through pipelines, a coarse filter membrane component and a fine filter membrane component are arranged in the brine recovery tank, and a stirring mechanism and a feeding mechanism are arranged in the propagation expansion tank. Further, a pump and a valve for adjusting the flow and the pressure are arranged on the liquid inlet pipeline of the brine recovery tank. Further, the brine recovery tank is provided with a backflush device for cleaning the filter assembly. Further, the brine recovery tank and/or the propagation tank are/is provided with a detection device, and the detection device comprises at least one of an oxygen solubility detector, a pH detector and an acidity detector. Further, the feeding mechanism comprises at least one of a carbon source feeder, a nitrogen source feeder, a trace element feeder and an alkali liquor feeder. Further, the coarse filtration membrane component is a 80-150 mesh screen.

Further, the propagation tank is provided with a heating device for controlling the temperature between 25 ℃ and 30 ℃. Further, the liquid outlet pipeline of the brine recovery tank can be selectively communicated to the propagation tank or the fermentation tank so as to respectively perform brine microorganism propagation or brine circulation treatment.
