Description

Technical Field

[0001] This invention relates to the field of blending and detection technology in baijiu (Chinese liquor) production processes, specifically to a blending and detection device for baijiu production processes. Background Technology

[0002] Baijiu, also known as shaojiu, is a unique distilled spirit from China. It is one of the world's eight major distilled spirits, along with brandy, whiskey, vodka, gin, rum, tequila, and Japanese sake. Baijiu is primarily made from starch or sugar-based raw materials, fermented into mash or malt, which is then distilled. It is colorless or slightly yellow and transparent, with a pure and fragrant aroma, a smooth and sweet taste, and a relatively high alcohol content. After aging, it develops a complex aroma dominated by esters. Baijiu is produced through processes such as cooking, saccharification, fermentation, distillation, and aging. Due to differences in production conditions and actual circumstances in different workshops, the taste of the produced baijiu varies. Therefore, baijiu requires blending to achieve uniformity. Blending baijiu is not simply adding water; rather, it involves combining different base spirits, raw spirits, semi-finished spirits, and water to flavor the spirit, balance its flavor, remove impurities, harmonize its aroma, and preserve its unique style.

[0003] Due to the limitations of the production process of baijiu, various situations will be encountered during the blending and testing process, not just the one mentioned below. More specifically, in the process of blending and testing, traditional blending relies on sensory organs (mouth, nose, and eyes) to judge the quality of the liquor and on experience to make different combinations of liquors. Due to the differences in sensitivity and accuracy between the two, and the individual differences, different batches of blended liquor will be produced, resulting in quality fluctuations. At the same time, in large-capacity storage tanks, blending is carried out by calculating the amount of various base liquors according to the formula determined by the small sample, and then conducting blending and testing. During the testing process, the uneven mixing of various base liquors can easily cause testing errors, thereby reducing production efficiency.

[0004] Therefore, we propose a blending and detection device for baijiu (Chinese liquor) production to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a blending and detection device for baijiu (Chinese liquor) production processes, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a blending and testing device for baijiu (Chinese liquor) processing, comprising a processing table, a supporting base installed at the bottom of the processing table, a transfer mechanism for transferring and sorting test tubes installed at the top of the supporting base, a vertically mounted dual-axis motor installed between the processing table and the supporting base, a testing mechanism fixedly installed at the top of the processing table, a transfer mechanism for transferring test tubes to the bottom of the testing mechanism for testing installed at the top of the processing table, the output end of the top of the dual-axis motor fixedly connected to the transfer mechanism, the output end of the bottom of the dual-axis motor fixedly connected to the transfer mechanism, and a guide feeding mechanism adapted to the transfer mechanism fixedly installed at the top of the processing table and at the outer ring of the transfer mechanism.

[0007] Preferably, the transfer mechanism includes a rotating rod, a bearing, a slot, and a first turntable. The first turntable is located at the top of the processing table and inside the guide feeding mechanism. The bearing is embedded inside the first turntable. The surface of the rotating rod is fixedly connected to the inner wall of the bearing. There are multiple sets of slots, which are circumferentially formed on the outer ring of the first turntable. The bottom end of the rotating rod is fixedly connected to the output end of the top of the motor.

[0008] Preferably, the material transfer mechanism includes a second turntable, a tube clamping assembly, and a rotating column. The second turntable is rotatably mounted on the top of the support base. The top of the second turntable is fixedly connected to the rotating column. The top of the rotating column is fixedly connected to the output end of the bottom of the motor. The tube clamping assembly is embedded inside the second turntable.

[0009] Preferably, the tube clamping assembly includes a first tube clamping pad, an outer tube clamping tube, a connecting rod, a second tube clamping pad, and a base support. The first tube clamping pad is fixedly installed on the inner wall of the outer tube clamping tube, the bottom end of the connecting rod is fixedly connected to the base support, the second tube clamping pad is fixedly installed on the inner wall of the base support, the outer tube clamping tube is fixedly installed on the inner wall of the second turntable, and the base support is movably installed on the inner wall of the second turntable.

[0010] Preferably, the bottom of the outer clamping tube is provided with an installation groove, a tension spring is fixedly installed on the inner wall of the installation groove, a movable block is fixedly installed at the bottom end of the tension spring, and the top end of the connecting rod is fixedly connected to the movable block.

[0011] The system is expanded by incorporating a transfer mechanism. This mechanism rotates synchronously with the transfer mechanism during its rotational detection process. After the test tubes are transferred and fall, they are cushioned and protected by an internal clamping component, preventing damage and facilitating sorting and marking to correspond with the data collected by the testing mechanism, thus increasing testing efficiency.

[0012] Preferably, the detection mechanism includes a column, a cylinder, a retaining ring, and an ethanol detector. The bottom of the column is fixedly connected to the top of the processing table, the cylinder is fixedly installed on the top of the processing table, the lifting end of the cylinder is fixedly connected to the retaining ring, and the ethanol detector is fixedly installed inside the retaining ring.

[0013] Preferably, the guiding feeding mechanism includes a guide recess, a connecting plate, a guide ring, and multiple sets of guide balls. The guide ring is fixedly installed on the top of the processing table, the guide recess is fixedly installed on the surface of the guide ring, the connecting plate is fixedly installed at the tail end of the guide recess, and the guide balls are circumferentially and equidistantly distributed and embedded inside the guide ring.

[0014] The expansion involves the coordinated use of a transfer mechanism and a guiding feeding mechanism. An external pushing structure pushes the test tubes from the guiding feeding mechanism to the transfer mechanism, which then transfers the test tubes sequentially to the bottom of the testing mechanism for inspection. No manual operation is required during this process. The test tubes are positioned between the slot and the guide balls. The rotation of the test tubes during the turning process creates a slight shaking effect, preventing sedimentation and other issues that could affect the testing results.

[0015] Preferably, the interior of the processing table is internally installed with a guide conveying pipe for guiding the test tube in the transfer mechanism to the material transfer mechanism. A fixing ring is fixedly installed on the surface of the motor. A fixing plate is fixedly installed on the surface of the fixing ring. A positioning ring is fixedly installed on the left end of the fixing plate. A fixing column is fixedly installed on the inner wall of the positioning ring. The top and bottom ends of the fixing column are fixedly connected to the processing table and the support base, respectively.

[0016] Preferably, two sets of limiting plates are fixedly installed on the surface of the supporting base, and a placement plate is placed between the two sets of limiting plates. The top of the placement plate has multiple placement slots.

[0017] Preferably, the bottom of the second turntable and the top of the support base are provided with ball grooves, and a rotating ball is rotatably connected between the two sets of ball grooves.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] First, this invention, through the cooperation of a transfer mechanism and a guiding feeding mechanism, uses an external pushing structure to push the test tubes from the guiding feeding mechanism to the transfer mechanism. The transfer mechanism then transfers the test tubes, moving them sequentially to the bottom of the testing mechanism for testing. No manual operation is required during this process. The test tubes are positioned between the slot and the guide ball. During the turning process, the test tubes rotate, thus agitating them and preventing sedimentation that could affect the testing results.

[0020] Secondly, this invention incorporates a transfer mechanism that rotates synchronously with the transfer mechanism during its rotation detection. This allows the test tubes, after the transfer detection is completed, to fall from the transfer mechanism into the transfer mechanism. Upon entering the transfer mechanism, the internal tube-clamping component provides cushioning protection, preventing damage and facilitating sorting and marking to correspond with the data detected by the testing mechanism, thus increasing testing efficiency.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Manual blending of different liquors based on experience is prone to errors due to variations in sensitivity and accuracy, resulting in inconsistent batches and quality fluctuations. Furthermore, in large-capacity storage tanks, blending involves calculating the amounts of various base liquors according to a small-sample formula before testing. Inconsistent mixing of the base liquors during testing can easily lead to errors and reduce efficiency. The following solutions address this issue:

[0033] Please see Figure 1-6 A blending and testing device for baijiu (Chinese liquor) production includes a processing table 1, a support base 10 installed at the bottom of the processing table 1, a vertically mounted dual-axis motor 15 installed between the processing table 1 and the support base 10, a testing mechanism 4 fixedly installed at the top of the processing table 1, and a transfer mechanism 2 installed at the top of the processing table 1 for transferring test tubes to the bottom of the testing mechanism 4 for testing. The output end of the top of the dual-axis motor 15 is fixedly connected to the transfer mechanism 2, and the output end of the bottom of the dual-axis motor 15 is fixedly connected to the material transfer mechanism 3.

[0034] The transfer mechanism 2 includes a rotating rod 201, a bearing 202, a slot 203, and a first turntable 204. The first turntable 204 is located on the top of the processing table 1 and inside the guide feeding mechanism 5. The bearing 202 is embedded in the inside of the first turntable 204. The surface of the rotating rod 201 is fixedly connected to the inner wall of the bearing 202. There are multiple sets of slots 203, which are circumferentially opened on the outer ring of the first turntable 204. The bottom end of the rotating rod 201 is fixedly connected to the output end of the top of the motor 15. The transfer mechanism 2 can transfer the test tubes and move them to the bottom of the detection mechanism 4 for detection in sequence. No manual operation is required during this process.

[0035] The detection mechanism 4 includes a column 401, a cylinder 402, a retaining ring 403, and an ethanol detector 404. The bottom of the column 401 is fixedly connected to the top of the processing table 1. The cylinder 402 is fixedly installed on the top of the processing table 1. The lifting end of the cylinder 402 is fixedly connected to the retaining ring 403. The ethanol detector 404 is fixedly installed inside the retaining ring 403. Through the detection mechanism 4, the ethanol content in the wine can be detected.

[0036] The guiding feeding mechanism 5 includes a guide concave block 501, a connecting plate 502, a guide ring 503, and multiple sets of guide balls 504. The guide ring 503 is fixedly installed on the top of the processing table 1, the guide concave block 501 is fixedly installed on the surface of the guide ring 503, the connecting plate 502 is fixedly installed at the tail end of the guide concave block 501, and the guide balls 504 are circumferentially and equidistantly distributed and embedded inside the guide ring 503. Through the external pushing structure, the test tube in the guiding feeding mechanism 5 can be pushed to the transfer mechanism 2, realizing the effect of guiding transmission. At the same time, it can drive the test tube to rotate, thereby shaking the test tube and avoiding sedimentation and other phenomena that affect the detection effect.

[0037] The interior of the processing table 1 is equipped with a guide pipe 6 for guiding the test tubes in the transfer mechanism 2 to the guide conveying pipe 6 in the transfer mechanism 3. A fixing ring 14 is fixedly installed on the surface of the motor 15. A fixing plate 13 is fixedly installed on the surface of the fixing ring 14. A positioning ring 12 is fixedly installed on the left end of the fixing plate 13. A fixing column 11 is fixedly installed on the inner wall of the positioning ring 12. The top and bottom ends of the fixing column 11 are fixedly connected to the processing table 1 and the support base 10, respectively. Through the guide conveying pipe 6, the test tubes can be guided from the first turntable 204 to the second turntable 301. The fixing ring 14, the fixing plate 13, the positioning ring 12, and the fixing column 11 connect the processing table 1 and the support base 10, and fix the motor 15 in a suspended position.

[0038] The specific implementation of this embodiment is as follows: Through the external pushing structure, the test tube containing wine can be pushed into the interior of the guide recess 501, and then pushed into the interior of the slot 203 through the guide recess 501 and the connecting plate 502. Under the rotation of the dual-axis motor 15, the test tube stuck in the slot 203 can be rotated. During this process, it will come into contact with the guide ball 504, thereby driving the rotation of the guide ball 504, and thus realizing the transfer of the test tube. During this process, the test tube will rotate with the rotation, which can shake the wine inside to avoid sedimentation. When it rotates to the bottom of the detection mechanism 4, the cylinder 402 drives the ethanol detector 404 to probe downward into the test tube for detection through the locking ring 403. After the test is completed, the test tube will continue to rotate. When it rotates to the top of the guide conveying pipe 6, it will fall into the transfer mechanism 3 through the guide conveying pipe 6 for sequential arrangement.

[0039] Example 2: After the test is completed, the test tubes need to be transferred and sorted to correspond with the test data. This is solved by the following solution:

[0040] Please see Figure 1-9 A blending and testing device for baijiu (Chinese liquor) processing also includes a material transfer mechanism 3 and a guiding feeding mechanism 5. The material transfer mechanism 3, which is used to transfer and sort the test tubes, is fixedly installed on the top of the support base 10, and the guiding feeding mechanism 5 is installed on the top of the processing table 1 and located at the outer ring of the material transfer mechanism 2.

[0041] The transfer mechanism 3 includes a second turntable 301, a tube clamping assembly 302, and a rotating column 303. The second turntable 301 is rotatably mounted on the top of the support base 10. The top of the second turntable 301 is fixedly connected to the rotating column 303. The top of the rotating column 303 is fixedly connected to the output end of the bottom of the motor 15. The tube clamping assembly 302 is embedded in the interior of the second turntable 301. By setting the transfer mechanism 3, the transfer mechanism 3 can rotate synchronously with the rotation of the transfer mechanism 2 while the transfer mechanism 2 is performing rotation detection. This allows the test tubes that fall after the transfer detection to fall from the transfer mechanism 2 to the transfer mechanism 3, facilitating sorting and marking to correspond with the data detected by the detection mechanism 4, thus increasing detection efficiency.

[0042] The tube clamping assembly 302 includes a first tube clamping pad 3021, an outer tube clamping tube 3022, a connecting rod 3023, a second tube clamping pad 3024, and a base support 3025. The first tube clamping pad 3021 is fixedly installed on the inner wall of the outer tube clamping tube 3022. The bottom end of the connecting rod 3023 is fixedly connected to the base support 3025. The second tube clamping pad 3024 is fixedly installed on the inner wall of the base support 3025. The outer tube clamping tube 3022 is fixedly installed on the inner wall of the second turntable 301. The base support 3025 is movably installed on the inner wall of the second turntable 301. An installation groove 3028 is provided at the bottom of the outer tube clamping tube 3022. A tension spring 3027 is fixedly installed on the inner wall of the mounting groove 3028. A movable block 3026 is fixedly installed at the bottom end of the tension spring 3027. The top end of the connecting rod 3023 is fixedly connected to the movable block 3026. Through the tube clamping assembly 302, the bottom of the test tube will contact the second tube clamping pad 3024 inside the base 3025. The weight moves the base 3025 downward, and the base 3025 in turn moves the connecting rod 3023 downward. The connecting rod 3023 pulls the tension spring 3027 through the movable block 3026, thereby buffering the force of falling and preventing damage to the test tube.

[0043] Two sets of limiting plates 7 are fixedly installed on the surface of the supporting base 10. A placement plate 8 is placed between the two sets of limiting plates 7. Multiple placement slots 9 are opened on the top of the placement plate 8. Through the limiting plates 7, the placement plate 8 and the placement slots 9, the limiting plates 7 can limit the placement plate 8, while the placement slots 9 on the top of the placement plate 8 can be used to put in the limiting test tube.

[0044] Both the bottom of the second turntable 301 and the top of the support base 10 are provided with ball grooves 16. Rotating balls 17 are rotatably connected between the two sets of ball grooves 16. Through the ball grooves 16 and the rotating balls 17, as the second turntable 301 rotates, the rotating balls 17 will roll inside the ball grooves 16 to achieve a stable support.

[0045] The specific implementation method of this embodiment is as follows: The test tube falling from the guide conveying tube 6 will enter the tube clamping mechanism. When the test tube enters, the bottom of the test tube will contact the second tube clamping pad 3024 inside the base 3025. The weight will drive the base 3025 downward, and the base 3025 will drive the connecting rod 3023 downward. The connecting rod 3023 will pull the tension spring 3027 through the movable block 3026, thereby buffering the force of the falling test tube and preventing damage to the test tube. After the falling is completed, the second turntable 301 will rotate synchronously with the first turntable 204. The two are synchronized, and the fallen test tube will be rotated to one side and collected in sequence to correspond to the test results of the previous step. This is convenient, fast, and has high accuracy and efficiency.
