[0001] The utility model relates to the technical field of brewing cellars, in particular to a cellar sealing device which is convenient for sampling and monitoring inside the cellar. Background Art

[0002] Chinese baijiu, one of the world's six major distilled spirits, boasts a long history. Luzhou-flavor liquor differs most significantly from other styles in its "cellar solid-state fermentation, continued mash addition, and co-steaming and co-firing." To achieve an airtight, anaerobic fermentation process, cellar mud is typically used to seal the cellar. However, as brewing cycles increase, the mud accumulates chaff, and using this mud as a sealer can result in a loose seal, leading to bacterial contamination during fermentation. Furthermore, using mud to seal the cellar is time-consuming and labor-intensive, resulting in a waste of labor. Utility Model Content

[0019] The following will be combined with the accompanying drawings of the present invention to clearly and completely describe the technical solution of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a cellar sealing device for facilitating sampling and cellar monitoring is composed of a support 1 and a cover 2 fitted on the top of the support 1, both of which are made of stainless steel; the support 1 is fixedly arranged on the top of the cellar, and a cover groove 3 is circumferentially provided on the top of the support 1; a plurality of hanging rings 4 and a plurality of sampling holes 5 longitudinally passing through the cover 2 are provided on the top of the cover 2, and an axial hole longitudinally passing through the cover 2 is provided on one side of each of the sampling holes 5, and a sealing wall 6 extending into the cover groove 3 is provided on the bottom edge of the cover 2; a ventilation chamber 18 is connected to the top of each of the sampling holes 5, and A ventilation hole is provided on one side of each ventilation chamber 18, and a window and a screw cover 14 threadedly engaged with the window are provided on the top of the ventilation chamber 18; the bottom end of each sampling hole 5 is equipped with a cover plate 7, and a control shaft 8 is provided on one side of each cover plate 7, and each control shaft 8 extends to the top of the cover body 2 through the corresponding shaft hole, and a switch handle 9 is provided on the top of each control shaft 8; a gas cylinder 17 is provided on one side of each ventilation chamber 18, and each gas cylinder 17 is connected to the ventilation hole through a ventilation pipe 11, and a valve 10 is provided in each ventilation pipe 11.

[0021] Through the above structure, after the grain is put into the cellar, the staff will connect the lifting ring 4 of the cover body 2 to the lifting equipment and move it to the top of the cellar and the cover groove 3 on the top of the support 1, wherein the support 1 is embedded in the top of the cellar by cement, and the cover groove 3 is sealed and welded to the top of the support 1 and separated from the cellar mud to ensure that the cover body 2 will not crush the cellar. In addition, low-concentration sulfuric acid is injected into the cover groove 3 so that the gas generated in the cellar during the fermentation process can be discharged, ensuring that the internal and external air pressures are consistent, and also preventing the growth of microorganisms and preventing contamination of miscellaneous bacteria during the fermentation process that affects the quality of the wine. During the sampling process, the staff controls the switch handle 9 to put the cover plate 7 in a closed state, then opens the screw cap 14, and sprays alcohol into the ventilation chamber 18 for burning, and then combines the sampler with the matching silicone cover with the ventilation chamber 18. Afterwards, the staff connects the inert gas cylinder 17 to the ventilation chamber 18 via the ventilation pipe 11, opens the valve 10 to introduce the inert gas into the ventilation chamber 18, and finally opens the cover 7 using the switch handle 9 to perform the sampling operation. The advantages of this structure are that it can monitor the fermentation process in the cellar, and the alcohol burning and sterile inert gas injection into the sampling hole 5 ensure that the fermentation in the cellar is not affected during the sampling process.

[0022] A silicone sealing gasket is provided at the bottom of the screw cover 14 corresponding to the top area of the ventilation chamber 18 , and at the top of the cover plate 7 corresponding to the bottom area of the sampling hole 5 .

[0023] In this arrangement, the silicone sealing gasket can effectively ensure the airtightness of the sampling hole 5, and the silicone sealing gasket of the screw cover 14 can be replaced after each sampling.

[0024] The free end of each ventilation pipe 11 is threadedly engaged with the ventilation hole, and each ventilation pipe 11 is provided with a gas filter membrane 16 between the valve 10 and the ventilation chamber 18. The ventilation pipe 11 is also connected to a pressure gauge.

[0025] In this arrangement, a gas filter membrane 16 is provided in the pipeline to ensure that the inert gas delivered by the gas cylinder 17 to the ventilation pipeline 11 is sterile gas, so that before the sampler is inserted into the sampling hole 5, the environment inside the sampling hole 5 is a sterile and oxygen-free environment.

[0026] Each of the control shafts 8 is matched with the shaft hole through a sealed bearing. A baffle 15 is vertically connected to one side of the bottom of the cover plate 7 corresponding to each of the sampling holes 5.

[0027] In this arrangement, the sealed bearing ensures smooth movement of the cover plate 7, while the baffle 15 prevents the sampling hole 5 from being loosely closed due to excessive rotation of the cover plate 7.

[0028] The cover 2 is provided with a plurality of longitudinally penetrating monitoring holes 12, and a gas probe 13 is provided at the bottom of each monitoring hole 12. The sampling holes 5 and the monitoring holes 12 are distributed in the center and surrounding areas of the cover 2.

[0029] During the fermentation process, the gas probe 13 in this arrangement is used to detect the ratios of various gas components within the cellar and is connected to a detection system to monitor the fermentation status. The multiple sampling holes 5 and monitoring holes 12 ensure that the extracted mash is representative and that samples can be taken at different depths, thereby obtaining more comprehensive data to understand the fermentation status within the cellar.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
