Description

TECHNICAL FIELD

[0001] The utility model relates to a back-irrigation device, in particular to a pickled vegetable pool fermentation back-irrigation device capable of improving fermentation stability, and belongs to the technical field of pickled vegetable production. BACKGROUND

[0002] The pickled vegetable pool fermentation back-irrigation device realizes the recycling of brine by extracting the brine or sauce accumulated at the bottom of the pickled vegetable fermentation pool and then uniformly irrigating it on the surface of the pickled vegetable. The back-irrigation has the advantage of making the salt content in each part of the pickled vegetable more uniform, promoting the uniform fermentation of the pickled vegetable, and in addition, helping to remove the odor produced in the vegetable tissue and preventing spoilage.

[0003] In the traditional pickled vegetable pool fermentation back-irrigation system, the brine circulation device usually consists of a plastic or metal pipeline and a centrifugal pump to form a basic closed loop structure. The bottom brine is extracted by the mechanical pump and uniformly sprayed to the surface layer of the pool body. This device has the following problems in use:

[0004] 1. The back-irrigation process lacks a temperature dynamic regulation mechanism. The brine is significantly affected by environmental temperature fluctuations during circulation, resulting in a large temperature gradient deviation at different depths in the pool, which causes metabolic disorder of the bacterial population.

[0005] 2. The back-irrigation leads to continuous loss of the bacterial population. Part of the attached bacteria is trapped by the pipeline filter screen during each cycle, and the shear force generated by the high-speed flowing brine can damage the bacterial biofilm structure, causing the active bacterial population density to decrease week by week. The back-irrigation system has neither a bacterial population monitoring unit nor an automatic bacterial supplement device. The operating personnel need to manually add freeze-dried bacterial powder regularly according to experience. This discrete bacterial supplement method causes the concentration of lactic acid bacteria in the pool to fluctuate dramatically, resulting in a peak value of nitrite exceeding the standard and prolonging the fermentation period.

[0006] Therefore, a pickled vegetable pool fermentation back-irrigation device capable of improving fermentation stability is proposed. CONTENT OF THE UTILITY MODEL
