Description

Technical Field

[0001] The utility model relates to the technical field of wine-making equipment, in particular to a telescopic auxiliary device for returning strong-flavor liquor to a cellar. Background Art

[0002] The fermented mother lees has an ethanol content of about 5%, and also contains a large number of flavor components with very small content. Distillation is required to extract the ethanol and flavor components contained therein. Traditional craft liquor uses a steamer as a distiller, and its distillation process follows Raoult's law. Since the boiling points of various components are different, and their volatility is also affected by the concentration of ethanol, the time for different components to be distilled during the distillation process is different. The head of the wine contains more esters, higher alcohols, aldehydes, acids, methanol and other substances, and the tail of the wine contains more acids. There are also some non-volatile components with high boiling points, which are mainly dragged out through mist entrainment, such as lactic acid and its ethyl ester, glycerol, etc. Because the content of higher alcohols such as methanol in the head of the wine is high, and the content of higher acid esters in the tail of the wine is high and the flavor is strong, the practice of "cutting the head and tail" is usually adopted, that is, the head and tail of the wine (alcohol content below 55 degrees) are picked and stored separately, and usually disposed of by splashing the cellar wall, re-distillation, and abandonment. The utilization rate is not high, resulting in waste of fermentation products. The large amount of acids, esters and alcohols contained in the head and tail of the wine are the direct substrates in the aroma production process of the liquor. If they can be added back into the cellar and participate in the fermentation process again, they can be converted into the aroma components of the liquor, which is more conducive to improving the quality of the wine.

[0003] At present, the practice of returning to fermentation is rarely used in the production of strong-flavor liquor. Even if the process is adopted, the returned wine mash is usually spread out to dry and koji is added, and then it is manually sprinkled in layers when entering the cellar for the next round. Because the sprinkler is an open manual operation, it is easy to cause volatile losses; the return time is when the new round of fermentation has not yet started when entering the cellar, and the sprinkled alcohol has a certain inhibitory effect on the start of saccharification and fermentation, which is not conducive to the overall fermentation. Therefore, too much wine cannot be returned, the amount added is limited, and the effect of improving product quality is limited.

[0004] Therefore, in the production process of Luzhou-flavor liquor, how to transport the returned liquor (head and tail) to the bottom of the fermentation tank within the appropriate fermentation cycle to achieve effective utilization of the returned liquor and improve the quality of the liquor is an urgent problem to be solved. Utility Model Content

[0012] Furthermore, an upper limit ring and a lower limit ring are respectively arranged at the upper and lower parts of the external thread section.

[0014] The beneficial effects of the present utility model are as follows: The structure of the present utility model is simple and convenient for processing and manufacturing.

Specific implementation manner

[0024] The following will combine specific embodiments and attached Figures 1-7 , and clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only some preferred embodiments of the present utility model, rather than all embodiments. Those skilled in the art can make similar deformations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] The present utility model provides a telescopic auxiliary device for returning strong-flavor Baijiu to the cellar (such as Figure 1As shown in the figure, it includes an outer sleeve 1 and an inner sleeve 2. The inner sleeve 2 is sleeved inside the outer sleeve 1, and the inner sleeve 2 can slide up and down and be positioned inside the outer sleeve 1. In practical applications, the outer sleeve 1 is used to realize the insertion and positioning of the device in the fermentation tank. To facilitate the smooth insertion of the outer sleeve 1 into the fermented grains in the fermentation tank, the bottom of the outer sleeve 1 can be made conical. To facilitate the visualization of the insertion depth through the outer sleeve 1, depth measurement scales can be provided on the outer side wall of the outer sleeve 1. The starting position of the depth measurement scales is the bottom of the outer sleeve 1. The inner sleeve 2 is used to realize the initial loading and diversion of the returned wine. During the operation of returning wine, a water pump is used to continuously input the returned wine into the inner sleeve 2, and then it is convenient for the returned wine to enter the bottom of the fermentation tank subsequently. At the inner bottom of the outer sleeve 1, there are several guiding cavities 11 evenly distributed along its circumferential direction. In practical applications, the guiding cavity 11 can be a fixed sleeve or a through guiding hole opened on a solid column 12 arranged inside the outer sleeve 1. The upper part of the guiding cavity 11 communicates with the inside of the outer sleeve 1, and the lower part of the guiding cavity 11 communicates with the outside. At the bottom of the inner sleeve 2, there are several elastic liquid guiding tubes 21 corresponding to the guiding cavities 11 one by one. The elastic liquid guiding tube 21 can be a plastic tube with a certain structural strength and can also be bent to a certain extent. The upper part of the elastic liquid guiding tube 21 communicates with the inside of the inner sleeve 2, and the lower part of the elastic liquid guiding tube 21 is sleeved inside the corresponding guiding cavity 11. The elastic liquid guiding tube 21 is used to realize the diversion and transportation of the liquid in the inner sleeve 2 to the wine cellar. In practical applications, when the inner sleeve 2 descends to a certain position inside the outer sleeve 1, the elastic liquid guiding tube 21 extends out of the guiding cavity 11. At this time, when the returned wine is continuously injected into the inner sleeve 2, the returned wine will continuously flow out through the elastic liquid guiding tube 21. A magnetic suction switch door 4 is arranged outside the lower opening of the guiding cavity 11. By using the magnetic suction switch door 4 to close the lower opening of the guiding cavity 11, during the process of inserting the outer sleeve 1 into the fermentation tank, the fermented grains in the fermentation tank can be effectively blocked from entering the guiding cavity 11, and then it can be effectively ensured that the elastic liquid guiding tube 21 can smoothly extend out of the guiding cavity 11. The switch door 4 is magnetically adsorbed on the outer sleeve 1. When the elastic liquid guiding tube 21 continuously moves downward in the guiding cavity 11, as the elastic liquid guiding tube 21 continuously moves, the elastic liquid guiding tube 21 pushes the switch door 4 to open, and then it is convenient for the elastic liquid guiding tube 21 to smoothly extend out of the lower opening of the guiding cavity 11 subsequently.

[0026] On the basis of the above embodiments, to facilitate the use of the elastic liquid guide tube 21 to achieve as uniform a distribution of the returned wine at the bottom of the fermentation tank as possible, so as to ensure the fermentation effect, here, the bottom of the elastic liquid guide tube 21 is in a closed state, and a number of liquid outlet holes 211 are provided on the side wall of the elastic liquid guide tube 21. Since there are many liquid outlet holes 211, they are distributed along the length direction of the elastic liquid guide tube 21, thus facilitating the effective and sufficient diffusion of the returned wine. In practical applications, the number of guiding cavities 11 can be set to three, and the number of elastic liquid guide tubes 21 is synchronously set to three, so that at least three equally spaced liquid outlet holes 211 are also provided in the circumferential direction of a certain position of the elastic liquid guide tube 21.

[0027] On the basis of the above embodiments, to facilitate the smooth up-and-down driving of the elastic liquid guide tube 21 by the inner sleeve 2, and at the same time, to facilitate the smooth telescopic movement of the elastic liquid guide tube 21 in the guiding cavity 11, here, the guiding cavity 11 is generally arc-shaped, and at the same time, the upper part of the guiding cavity 11 is in a vertical state, and the lower opening of the guiding cavity 11 is in a state of slanting downward.

[0028] To facilitate the convenience of taking the outer sleeve 1, here, two handles 14 are symmetrically provided on the upper part of the outer sleeve 1.

[0029] On the basis of the above embodiments, the specific implementation manner for the inner sleeve 2 to slide up and down and be positioned in the outer sleeve 1 is as follows: an L-shaped clamping plate 15 is provided at the connection between the handle 14 and the outer sleeve 1, an external thread section 22 is provided at a position above the middle of the inner sleeve 2, a telescopic adjusting nut 3 is sleeved on the external thread section 22, and the telescopic adjusting nut 3 is clamped between the upper bottom plane of the L-shaped clamping plate 15 and the upper plane of the outer sleeve 1, and the telescopic adjusting nut 3 can rotate freely. When the telescopic adjusting nut 3 is rotated, because the telescopic adjusting nut 3 is clamped on the upper part of the outer sleeve 1, through the thread matching relationship between the telescopic adjusting nut 3 and the external thread section 22, the inner sleeve 2 can move upward or downward. During the up-and-down movement of the inner sleeve 2, to effectively prevent the inner sleeve 2 from excessively squeezing the elastic liquid guide tube 21 downward and prevent the bottom of the elastic liquid guide tube 21 from detaching from the upper part of the guiding cavity 11, here, an upper limit ring 23 and a lower limit ring 24 are respectively provided on the upper and lower parts of the external thread section 22. When the upper limit ring 23 approaches the telescopic adjusting nut 3, the effective extension of the elastic liquid guide tube 21 in the guiding cavity 11 is achieved, and at the same time, it is ensured that the bottom of the inner sleeve 2 will not squeeze the upper part of the elastic liquid guide tube 21. When the lower limit ring 24 approaches the telescopic adjusting nut 3, it is ensured that the lower end of the elastic liquid guide tube 21 has completely retracted into the guiding cavity 11.

[0030] On the basis of the above embodiments, the specific implementation manner of the switch door 4 provided at the lower part of the outer sleeve 1 is as follows: A groove 131 is provided on the outer side of the lower opening of the guiding cavity 11. To facilitate the installation of the switch door 4, a thickening part 13 is provided on the outer side of the lower part of the outer sleeve 1, and the groove 131 is provided on the outer side wall of the thickening part 13. A switch door 4 is hingedly arranged in the groove 131. The upper part of the switch door 4 is provided with a hinge shaft 41 connected to the side wall of the groove 131. The switch door 4 can close and open the lower opening of the guiding cavity 11. When inserting this device into the bottom of the fermentation tank, to prevent the switch door 4 from being blocked or even pushed open by the fermented grains, here, the groove 131 is made to communicate with the outside at the upper part and be closed at the lower part. Further, the diameter of the upper top circle of the bottom conical end of the outer sleeve 1 is made equal to the outer diameter of the outer circle of the thickening part 13. A neodymium magnet 5 located at the lower opening of the guiding cavity 11 is provided on the groove 131. The neodymium magnet 5 can magnetically adsorb the lower part of the switch door 4. The switch door 4 is made of iron material. When this utility model is not in use, when the switch door 4 approaches the neodymium magnet 5, the magnetic characteristics of the neodymium magnet 5 are utilized to stably adsorb the switch door 4, and then the switch door 4 effectively closes the lower opening of the guiding cavity 11. When the elastic liquid guide tube 21 extends out, the pushing force of the elastic liquid guide tube 21 on the switch door 4 is greater than the magnetic adsorption force of the neodymium magnet 5 on the switch door 4, and then the opening of the switch door 4 can be realized.

[0031] In practical applications, when in a suitable white liquor fermentation cycle and it is necessary to inject the returned liquor at the bottom of the fermentation tank by using this utility model, the elastic liquid guide tube 21 is made to retract and remain in the guiding cavity 11, and at the same time, the switch door 4 is in a closed state.

[0032] The staff holds the handle 14 and slowly inserts the outer sleeve 1 vertically to the required depth, and then rotates the telescopic adjusting nut 3 to make the elastic liquid guide tube 21 slowly extend out of the guiding cavity 11. When the upper limit ring 23 approaches the telescopic adjusting nut 3, stop the extension action of the elastic guiding tube 21. Then, use a water pump to continuously inject the returned liquor into the inner sleeve 2. The returned liquor in the inner sleeve 2 diffuses into the fermentation tank through the guiding action of the elastic liquid guide tube 21, and then the injection operation of the returned liquor is realized. When the injection operation of the returned liquor at one position is completed, rotate the telescopic adjusting nut 3 to make the elastic liquid guide tube 21 retract into the guiding cavity 11. When the lower limit ring 24 approaches the telescopic adjusting nut 3, stop the retraction of the elastic liquid guide tube 21. At this time, slowly lift the outer sleeve 1 out of the fermentation tank through the handle 14, and then complete the injection process of the returned liquor at one position in the fermentation tank.

[0033] In this utility model, "upper", "lower", "front", "rear", "left", and "right" are all relative positions used for conveniently describing the position relationship, so they cannot be understood as absolute positions to limit the protection scope.

[0034] Except for the technical features described in the specification, the rest are well-known technologies to those skilled in the art.

[0035] As described above, the preferred embodiments and examples of the present utility model have been described in detail in conjunction with the accompanying drawings. However, the present utility model is not limited to the above-mentioned embodiments and examples. For those of ordinary skill in the art, without departing from the concept of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
