[0002] The solid-state fermentation cellar is a container used for fermentation in the solid-state fermentation process of liquor, and plays a key role in liquor brewing. By sampling the fermented grains in the cellar, the ingredients in the fermented grains can be tested, such as starch content, sugar content, acidity and other physical and chemical indicators. These indicators can reflect whether the fermentation process is normal.

[0003] China's authorization announcement number CN213749239U discloses a fixed-point sampling device for a liquor fermentation pit, comprising a first tube body and a second tube body, wherein a plurality of first sampling grooves respectively connected to the inner cavity of the first tube body are arranged at intervals along the axial direction on the tube wall of the first tube body, and the second tube body is inserted into the first tube body and can rotate relative to the first tube body, and a plurality of second sampling grooves respectively connected to the inner cavity of the second tube body are arranged at intervals along the axial direction on the tube wall of the second tube body, and the plurality of second sampling grooves correspond to the plurality of first sampling grooves in one-to-one position, and a plugging piece is also arranged below each first sampling groove in the second tube body, and the plurality of plugging pieces divide the inner cavity of the second tube body into a plurality of sampling cavities that are not connected to each other. The fixed-point sampling device for a liquor fermentation pit provided by the utility model can separate brewings of different depths when extracting brewings and is easy to clean, so as to facilitate the normal research and analysis of brewing components.

[0004] However, the device has the following defects when in use: the device is provided with a second sampling slot on the second tube body for storing samples, and the second tube body is sleeved on the first tube body. Therefore, after pouring out the sample, it is difficult to quickly remove the residual sample attached to the inner wall of the second sampling slot. In view of the above defects: To this end, we propose a liquor solid-state fermentation cellar sampling component. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a liquor solid-state fermentation cellar sampling component, comprising: a sampling rod, a sample holding structure, an assembly structure, a blocking structure and a locking component.

[0028] The sampling rod includes a hollow outer rod 10, an inner rod 11 sleeved on the inner wall of the hollow outer rod 10, a handle 12 fixedly mounted on the upper end of the inner rod 11, and a grip 13 fixedly mounted on the surface of the hollow outer rod 10. Rotating the handle 12 can drive the inner rod 11 to rotate on the inner wall of the hollow outer rod 10, and holding the grip 13 can fix the hollow outer rod 10.

[0029] The sample holding structure includes a sample holding outer cylinder 20, a sample holding inner cylinder 21 placed on the inner wall of the sample holding outer cylinder 20, and a fixing component arranged inside the sample holding outer cylinder 20 for fixing the sample holding inner cylinder 21. The number of the sample holding outer cylinders 20 is three, and the lower ends of the sample holding outer cylinder 20 and the hollow outer rod 10 are both configured to be conical, which is convenient for insertion into the white wine fermentation cellar. The three sample holding outer cylinders 20 can be used to sample the upper layer, middle layer and lower layer in the white wine fermentation cellar respectively.

[0030] The fixing assembly includes a stepped hole formed on the inner wall of the sample holding outer cylinder 20, an internal thread formed on the inner wall of the stepped hole, and a limiting ring 22 threadedly connected to the inner wall of the stepped hole via the internal thread. The sample holding inner cylinder 21 is placed into the sample holding outer cylinder 20, and then the limiting ring 22 is screwed into the stepped hole, so that the sample holding inner cylinder 21 can be fixed inside the sample holding outer cylinder 20 using the limiting ring 22.

[0031] An assembly structure is arranged on the surface of the sample holding outer cylinder 20, and is used to be assembled with the inner rod 11 as a whole. It includes a threaded rod 30 fixedly mounted on the surface of the sample holding outer cylinder 20, three threaded holes equidistantly arranged on the surface of the inner rod 11, and three arcuate track grooves 31 equidistantly arranged on the surface of the hollow outer rod 10. The center of the arcuate track groove 31 is coaxial with the center of the inner rod 11, and the arcuate track groove 31 allows the threaded rod 30 to pass through. The threaded rod 30 is passed through the arcuate track groove 31 and then screwed into the threaded hole, so that the sample holding outer cylinder 20 and the inner rod 11 can be assembled as a whole. When sampling is completed, the sample holding outer cylinder 20 can be rotated to disengage the threaded rod 30 from the threaded hole, so that the sample holding outer cylinder 20 and the inner rod 11 can be separated, and the inner rod 11 can be pulled out and separated from the hollow outer rod 10, thereby facilitating the cleaning of the device.

[0032] The sealing structure is arranged on the surface of the hollow outer rod 10, and is used for sealing the opening of the sample holding outer cylinder 20. The sealing structure includes a baffle 40 fixedly mounted on the surface of the hollow outer rod 10, and an arc-shaped baffle ring 41 fixedly mounted on the lower surface of the baffle 40. The baffle 40 is located directly above the sample holding outer cylinder 20, and the inner diameter of the arc-shaped baffle ring 41 is larger than the outer diameter of the sample holding outer cylinder 20.

[0033] After the sample holding outer cylinder 20 and the inner rod 11 are fixed as one, the sampling rod is then inserted into the liquor fermentation cellar. At this time, the sample holding outer cylinder 20 will follow and enter the liquor fermentation cellar, and the three sample holding outer cylinders 20 will be respectively located in the upper, middle and lower layers of the liquor fermentation cellar. Then, the inner rod 11 is rotated, and the threaded rod 30 will slide along the inner wall of the arc track groove 31, thereby driving the sample holding outer cylinder 20 to rotate, so that the sample holding outer cylinder 20 is away from the baffle 40 and the opening of the sample holding outer cylinder 20 is exposed. Then, the sampling rod can be raised to make the mash in the liquor fermentation cellar enter the sample holding inner cylinder 21, and then the inner rod 11 is continued to be rotated to reset it, thereby completing the sampling. At this time, the sample holding outer cylinder 20 is directly below the baffle 40, and the baffle 40 can be used to block the opening of the sample holding outer cylinder 20, and the arc-shaped baffle ring 41 can limit the sample holding outer cylinder 20 to prevent it from excessive rotation and separation from the baffle 40.

[0034] The locking assembly is arranged on the surface of the hollow outer rod 10 and is used to fix the inner rod 11. The locking assembly includes a locking bolt 50 threadedly connected to the surface of the hollow outer rod 10 and a bolt hole opened on the surface of the inner rod 11, and the locking bolt 50 is adapted to the bolt hole. When the baffle 40 blocks the opening of the sample outer cylinder 20, the locking bolt 50 is screwed into the threaded hole, so that the inner rod 11 can be fixed to prevent the sample outer cylinder 20 from rotating away from the baffle 40 when the sampling rod is pulled out.
