Description

Technical Field

[0001] This utility model relates to the field of baijiu fermentation technology, specifically to an experimental container that facilitates sampling of baijiu fermentation mash. Background Technology

[0002] Baijiu is a distilled spirit unique to China and one of the world's eight major distilled spirits. It is made by distilling starchy or sugary mash after fermentation. It is also known as shaojiu, laobaigan, and shaodaozi.

[0003] In existing technologies, the normal brewing process usually requires frequent sampling and follow-up experiments, which can disrupt the microbial environment and fermentation state within the fermentation tank, thereby affecting the overall yield and quality of the liquor. To avoid this, and considering the actual conditions of brewing and experimentation, we have designed an experimental container that facilitates sampling of the fermenting mash for baijiu. Utility Model Content

[0004] The purpose of this invention is to provide an experimental container that facilitates sampling of fermented baijiu mash. It not only makes sampling of fermented baijiu mash easier and has a high degree of automation, reducing the labor intensity of workers, but also ensures the airtightness of the fermentation chamber during the sampling process, preventing the baijiu mash from deteriorating, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An experimental container for facilitating sampling of fermented liquor mash includes a fermentation chamber. A lid is mounted on the upper end of the fermentation chamber. A threaded hole is located in the center of the upper end of the lid. A sleeve is located above the threaded hole. A threaded opening that mates with the threaded hole is located at the lower end of the sleeve. A sampling rod is slidably mounted inside the sleeve. A sampling groove is located at the bottom of the sampling rod. A lifting mechanism that can raise and lower the sampling rod is located on the upper side of the sleeve. A strip-shaped groove is located on one side of the threaded hole at the bottom of the lid. An automatic sealing mechanism is provided between the strip-shaped groove and the threaded hole.

[0007] Furthermore, the lifting mechanism includes a screw and a motor. The screw is threaded in a threaded groove. The upper end of the screw is rotatably connected to the upper end of the sleeve through a sealed bearing. The motor is fixedly installed on the upper end of the sleeve. The output end of the motor is fixedly connected to the screw. Limiting blocks are fixedly provided on the upper ends of the two sides of the sampling rod. Limiting grooves that cooperate with the limiting blocks are provided on the inner walls of both sides of the sleeve.

[0008] Furthermore, the automatic sealing mechanism includes a sealing plate and a sliding rod. The sealing plate is located below the threaded hole and is hinged to the box cover on the side of the sealing plate near the strip groove. The sliding rod is horizontally fixed in the strip groove. A slider is slidably provided on the wall of the sliding rod. A spring is fixedly provided on the side of the sliding rod away from the sealing plate. A push rod is hinged to the lower side of the slider, and the other end of the push rod is hinged to the bottom of the sealing plate.

[0009] Furthermore, the spring is always in a compressed state.

[0010] Furthermore, a sealing ring is fixedly provided at the bottom of the box cover at the threaded hole.

[0011] Furthermore, the sealing ring is a corrosion-resistant rubber ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This baijiu fermentation mash sampling structure comprises a fermentation tank, a tank lid, a motor, a sleeve, a sealing plate, a sealing ring, a sampling groove, a sampling rod, a sliding rod, a spring, a slider, a push rod, a limit block, and a screw. When sampling the baijiu mash inside the fermentation tank, the threaded end of the sleeve is threaded into the threaded hole on the tank lid. The motor is then started, causing the screw to rotate clockwise. The screw and the threaded groove work together to move the sampling rod downwards. The lower end of the sampling rod pushes the sealing plate, causing the sealing plate to rotate from a horizontal to a near-vertical position. Simultaneously, the rotation of the sealing plate pushes the slider via the push rod. The slider slides on the sliding rod while simultaneously squeezing... As the spring is compressed and the lower end of the sampling rod is inserted into the fermented mash, the fermented mash is pushed into the sampling groove. Due to the small diameter of the sampling groove, the fermented mash remains in the sampling groove due to friction. The output end of the motor drives the screw to rotate counterclockwise and drives the sampling rod back into the sleeve. When the sampling rod is in the sleeve, the spring pushes the slider and drives the sealing plate to abut against the sealing ring through the push rod. At this time, the threaded end of the sleeve can be unscrewed from the threaded hole of the box cover. This not only facilitates the sampling of fermented mash for liquor, but also has a high degree of automation, reduces the labor intensity of the staff, and ensures the sealing of the fermentation box during the sampling process, preventing the liquor mash from deteriorating.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution:

[0021] An experimental container for facilitating sampling of fermented liquor mash includes a fermentation box 1, a box cover 2 installed on the upper end of the fermentation box 1, a threaded hole in the middle of the upper end of the box cover 2, a sleeve 4 on the upper side of the threaded hole, a threaded opening at the lower end of the sleeve 4 that matches the threaded hole, a sampling rod 8 slidingly installed inside the sleeve 4, a sampling groove 7 at the bottom of the sampling rod 8, and a strip groove at the bottom of the box cover 2 on one side of the threaded hole.

[0022] The upper side of the sleeve 4 is provided with a lifting mechanism that can drive the sampling rod 8 to rise and fall. The lifting mechanism includes a screw 14 and a motor 3. The screw 14 is threaded in the thread groove. The upper end of the screw 14 is rotatably connected to the upper end of the sleeve 4 through a sealed bearing. The motor 3 is fixedly installed on the upper end of the sleeve 4. The output end of the motor 3 is fixedly connected to the screw 14. Limiting blocks 13 are fixedly provided on the upper ends of the two sides of the sampling rod 8. Limiting grooves that cooperate with the limiting blocks 13 are provided on the inner walls of both sides of the sleeve 4.

[0023] An automatic sealing mechanism is provided between the strip groove and the threaded hole. The automatic sealing mechanism includes a sealing plate 5 and a sliding rod 9. The sealing plate 5 is located on the lower side of the threaded hole, and the side of the sealing plate 5 closest to the strip groove is hinged to the cover 2. The sliding rod 9 is horizontally fixed in the strip groove. A slider 11 is slidably provided on the wall of the sliding rod 9. A spring 10 is fixedly provided on the side of the wall of the sliding rod 9 away from the sealing plate 5. A push rod 12 is hinged to the lower side of the slider 11. The other end of the push rod 12 is hinged to the bottom of the sealing plate 5. The spring 10 is always in a compressed state and can always push the sealing plate 5.

[0024] A sealing ring 6 is fixedly installed at the bottom of the box cover 2 at the threaded hole. The sealing ring 6 can improve the sealing between the threaded hole and the sealing plate 5. The sealing ring 6 is a corrosion-resistant rubber ring. The corrosion-resistant rubber ring has good corrosion resistance, is not easily corroded, and has a long service life.

[0025] When sampling the liquor mash in fermentation tank 1 is required, the threaded end of the sleeve 4 is threaded into the threaded hole on the tank cover 2. At this time, the motor 3 is started, and the motor 3 drives the screw 14 to rotate clockwise. The screw 14 and the threaded groove cooperate to move the sampling rod 8 downwards. The lower end of the sampling rod 8 pushes the sealing plate 5, which rotates from a horizontal position to a near-vertical position. Simultaneously, the sealing plate 5 rotates and pushes the slider 11 through the push rod. The slider 11 slides on the sliding rod 9 while compressing the spring 10. As the lower end of the sampling rod 8 is inserted into the liquor mash, the fermented liquor mash is inserted into the sampling groove 7. Because... The sampling trough 7 has a small diameter, and the fermented mash remains in the sampling trough 7 due to friction. The output end of the motor 3 drives the screw 14 to rotate counterclockwise and drives the sampling rod 8 back into the sleeve 4. When the sampling rod 8 is in the sleeve 4, the spring 10 pushes the slider 11 and drives the sealing plate 5 to abut against the sealing ring 6 through the push rod 12. At this time, the threaded end of the sleeve 4 can be unscrewed from the threaded hole of the box cover 2. This not only facilitates the sampling of the fermented mash of liquor, but also has a high degree of automation, reduces the labor intensity of the staff, and ensures the sealing of the fermentation box during the sampling process, preventing the liquor mash from deteriorating.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
