Description

Technical Field

[0001] The utility model relates to the field of wine brewing, and more specifically to an anaerobic spraying device for cellar maintenance. Background Art

[0002] Cellars are the main fermentation containers for brewing Luzhou-flavor liquor and are also important places for the formation of liquor flavor components. During the long-term brewing process, the degradation of cellar mud is relatively prominent, especially the mud on the cellar walls, which seriously affects the quality of the cellars. In this regard, the Chinese invention patent with the application number CN202010250724.7 proposes a method for promoting the ripening of Luzhou-flavor liquor cellar mud through the yellow water fermentation broth of old cellars. Fresh yellow water from old cellars is used as raw material, which is diluted, pH-adjusted, and anaerobically fermented and cultured, and then used for the production, maintenance, and large-scale cultivation of cellar mud in cellars, so as to promote the improvement of Luzhou-flavor liquor cellar mud and enhance the brewing quality of Luzhou-flavor liquor.

[0003] Since the above-mentioned yellow water fermentation broth of old cellars contains a large number of anaerobic bacteria such as caproic acid bacteria and methanogens, if stored open, the anaerobic bacteria in the yellow water fermentation broth of old cellars will be lost. At present, there is no effective storage method for the yellow water fermentation broth of old cellars. To avoid the invalidation of the yellow water fermentation broth of old cellars and meet the storage and maintenance operation requirements of the yellow water fermentation broth of old cellars, the present utility model proposes the following anaerobic spraying device for cellar maintenance. Summary of the Utility Model

[0004] To solve the above technical problems, the present utility model proposes an anaerobic spraying device for cellar maintenance, which provides a stable and reliable anaerobic environment for the storage of the yellow water fermentation broth of old cellars, effectively isolates the external environmental air, and has the function of directly outputting the yellow water fermentation broth of old cellars to the cellar mud to be maintained, providing a strong guarantee for the brewing quality.

[0005] To achieve the above purpose, the present utility model adopts the following technical solutions:

The gas phase space above the liquid level in the liquid storage tank is always filled with nitrogen gas through a gas pipe communicating with the nitrogen storage cavity. The piston can be displaced inside the gas storage tank relying on the pressure difference between the inside and outside.

[0010] The spraying pipeline is a horizontal pipe with multiple nozzles, which can horizontally extend inside the cellar to be maintained. There are gaps left between the two pipe ends and the closest pool walls respectively. The end with multiple nozzles faces the bottom or wall of the cellar to be maintained. Through the multiple nozzles, it inserts into the cellar mud at the bottom or on the wall of the pool. The other end has a liquid inlet, and through the liquid inlet, it is connected to the outlet end of the one-way valve via the liquid delivery pipe.

[0026] Please refer to Figures 1 to 2 , the anaerobic spraying device for cellar maintenance in this embodiment includes a liquid storage tank 1, a gas storage tank 4, and a spraying pipeline 3;

The cavity between the piston 41 and the top of the tank is communicated with the outside through the open top of the tank. The gas space above the liquid level in the liquid storage tank 1 is always filled with nitrogen gas through the connection with the nitrogen storage cavity via the gas pipe. The piston 41 can be displaced in the gas storage tank 4 depending on the internal and external pressure difference;

[0029] The spraying pipeline 3 is a horizontal pipe with multiple nozzles 32. It can extend horizontally in the cellar to be maintained. There are gaps between the two pipe ends and the closest pool wall respectively. The end with multiple nozzles 32 faces the bottom or the wall of the cellar to be maintained.
