Description

Technical Field

[0001] This utility model relates to the field of coffee fermentation sampling technology, specifically a multi-time-point aseptic sampling device for the coffee fermentation process. Background Technology

[0002] Coffee fermentation is a crucial process affecting coffee flavor formation. It involves complex microbial metabolic activities (such as yeast and lactic acid bacteria) and the dynamic transformation of sugars, organic acids, and alcohols. To precisely control the fermentation process, optimize flavor quality, and ensure process repeatability, producers and researchers typically need to sample the fermentation broth at multiple pre-set time points to detect key parameters such as pH, sugar content, alcohol content, organic acid composition, and microbial community structure. However, traditional sampling often involves temporarily opening the fermentation tank lid. Repeated opening or frequent punctures easily introduce external contaminants (such as acetic acid bacteria and mold), and the process is cumbersome and requires meticulous operation, easily leading to fermentation abnormalities or even failure. This problem is particularly pronounced in anaerobic or closed fermentation processes. Furthermore, the uncertain sampling location can cause inaccurate subsequent test data. Sampling is inconvenient and can even lead to fermentation failure and waste, making it extremely inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to provide a multi-time-point aseptic sampling device for coffee fermentation process, so as to solve the problem in the background art that the fermentation tank lid often needs to be opened during sampling, which can easily lead to fermentation failure and inaccurate sampling.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-time-point aseptic sampling device for coffee fermentation, comprising a sampling port, the sampling port being fixedly opened on the outer surface of the fermentation tank, and a shell being attached to one side of the sampling port, wherein the diameter of one end of the shell is the same as the diameter of one end of the sampling port, the sampling port being located on the bottom side surface of the fermentation tank, a multi-trough tank being rotatably installed inside the shell, a baffle plate being inserted and installed on the side of the shell near the sampling port, and the baffle plate being engaged with the shell, hard rubber partitions being uniformly fixed inside the multi-trough tank, and the outer surface of the hard rubber partitions being tightly fitted with the baffle plate, and a sealing mechanism being provided between the multi-trough tank and the shell.

[0005] Preferably, the sealing mechanism includes: a blocking rubber partition, which is embedded between the multi-slot tank and the hard rubber partition; a rubber plug is inserted into the end of the outer shell away from the sampling port, and the rubber plug engages with the outer shell; the rubber plug is located on one side of the blocking rubber partition.

[0006] By adopting the above technical solution, fermentation broth from multiple time periods can be extracted at one time, allowing a gap layer to be formed between the rubber stopper and the blocking rubber baffle, further reducing the entry of miscellaneous bacteria into the fermentation tank and affecting fermentation. Sampling can also be performed at multiple time points at a time, greatly improving the convenience of sampling.

[0007] Preferably, a sealing ring is placed on one side of the baffle plate, and the side surface of the sealing ring is in contact with the outer surface of the outer shell and the outer surface of the baffle plate, respectively, and the sealing ring is in contact with the outer surface of the sampling port.

[0008] By adopting the above technical solution, the sealing ring can seal both the outer shell and the baffle plate at the same time, and after the sampling device is used, the baffle plate, multi-slot bucket and other components can be removed from the outer shell for easy cleaning and disinfection.

[0009] Preferably, a suction tube is installed through one side of the outer surface of the baffle plate, and a filter basket is threadedly installed on the side of the suction tube away from the baffle plate. The outer surface of the filter basket is uniformly provided with filter holes, and the end of the filter basket away from the baffle plate is tapered.

[0010] By adopting the above technical solution, the coffee beans in the fermentation tank can be easily blocked by the filter basket, and the fermented liquid can be smoothly introduced into the suction tube. The sampling device can then take samples at specific points through the suction tube, making the data more accurate when the fermentation liquid is tested later.

[0011] Preferably, a knob is rotatably mounted on the outer surface of the outer shell, and a groove is formed on the outer surface of the knob. An elastic sliding mechanism is provided between the knob and the multi-groove barrel. The elastic sliding mechanism includes a spring, which is located inside the multi-groove barrel. The multi-groove barrel and the knob are respectively engaged with the spring. The knob and the multi-groove barrel are engaged, and the multi-groove barrel and the knob are slidably connected. Furthermore, the knob and the multi-groove barrel are concentrically designed.

[0012] By adopting the above technical solution, the spring allows the multi-tank tank and hard rubber partition to fit more tightly with the baffle plate, further reducing the chance of leakage from the outer shell when sampling the fermentation broth. At the same time, turning the knob can easily rotate the multi-tank tank to change the empty slots of the multi-tank tank for sampling, so that the fermentation broth sampled previously will not affect the current sampling, further improving the accuracy of sampling and measurement.

[0013] Preferably, time numbers are evenly distributed on the side of the outer shell away from the sampling port, and the time numbers are aligned with the groove of the knob. An elastic positioning mechanism is provided between the knob and the outer shell. The elastic positioning mechanism includes a spring piece, which is engaged with the outer surface of the knob. The outer surface of the outer shell is evenly distributed with grooves, and the grooves of the outer shell engage with the spring piece. A positioning block is fixedly installed on one side of the outer shell, and the positioning block is engaged with the sampling port.

[0014] By adopting the above technical solution, the rotation position of the knob and multi-slot bucket can be accurately confirmed and adjusted through the groove set on the outer surface of the outer shell and the spring sheet. After the knob is rotated to the corresponding position, it can be smoothly locked into the groove for fixation. The accuracy of the sampling time can be confirmed by the time digital, so that the multi-slot buckets will not be misaligned during sampling and affect the use.

[0015] Preferably, a clamping rod is rotatably mounted on the outer surface of the sampling port, and a time tag is fixedly mounted on the outer surface of the clamping rod. A piece of paper is inserted into the inside of the time tag. Rotating blocks are rotatably mounted on both sides of the sampling port, and quick-release screws are threaded onto the outer surface of the rotating blocks. One end of the quick-release screw is engaged with the clamping rod, and the outer surface of the clamping rod is in contact with the outer surface of the outer shell.

[0016] Using the above technical solution, the outer shell placed on the sampling port can be fixed and positioned by flipping the clamping rod, and the outer shell can be positioned and fixed by the positioning block. Then, with the rotation of the rotating block and the squeezing and rotating of the quick-release screw, the clamping rod can quickly squeeze and fix the outer shell. The initial fermentation time can be written and recorded by the time tag, which greatly improves the convenience of installation and disassembly after use.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the multi-time-point aseptic sampling device for coffee fermentation process: 1. The sampling port is located on the bottom side surface of the fermenter and rotates with the multi-tank design. The use of hard rubber baffles and blocking rubber baffles allows the fermentation liquid to enter the interior of the multi-tank. The position of the hard rubber baffles inside the multi-tank can be switched by rotating the baffles. When the needle is inserted into the rubber stopper and passes through the blocking rubber baffle to extract the fermentation liquid, it will not be affected by the residual fermentation liquid. This allows for sampling without frequently opening the fermenter lid and can extract samples at different times without affecting the fermentation liquid inside the fermenter. 2. The use of sealing rings can effectively seal the gaps between the baffle plate, the outer shell and the sampling port. At the same time, the use of springs allows the multi-tank tank and hard rubber partition to better contact and fit with the baffle plate, further reducing the chance of fermentation liquid leakage and mixing and contamination during sampling. In addition, the quick-release screw can be loosened and the rotating block can be rotated to disengage the quick-release screw from the clamping rod, and the outer shell, multi-tank tank, baffle plate and other parts can be easily removed for cleaning or replacement, which greatly improves practicality and the convenience of maintenance and cleaning. 3. The fermentation broth can be filtered through the suction tube and filter basket, preventing large debris from passing through the suction tube and entering the hard rubber baffle, which would cause blockage when the syringe is used for extraction. At the same time, the use of the suction tube allows for targeted sampling of the fermentation broth in the fermenter, which can further reduce errors caused by uncertain sampling locations and greatly improve the accuracy of sampling and measurement. 4. By inserting the positioning block into the sampling port, the positioning of the sampling port and the outer shell can be ensured. After the knob is turned, the multi-tank can rotate synchronously. With the engagement of the spring piece and the groove of the outer shell, the alignment and positioning of the knob and the time number can ensure that the aspiration tube can be accurately aligned with the hard rubber partition. This allows the sampling of fermentation broth to be aligned with the hard rubber partition in the unused multi-tank, further reducing contamination caused by positioning errors.

[0020] 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.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a multi-time-point aseptic sampling device for coffee fermentation, including a sampling port 1, which is fixedly opened on the outer surface of the fermentation tank. A shell 3 is attached to one side of the sampling port 1, and the diameter of one end of the shell 3 is the same as the diameter of one end of the sampling port 1. The sampling port 1 is located on the bottom side surface of the fermentation tank. A multi-trough tank 5 is rotatably installed inside the shell 3. A baffle plate 8 is inserted and installed on the side of the shell 3 near the sampling port 1, and the baffle plate 8 engages with the shell 3. Hard rubber partitions 6 are uniformly fixed inside the multi-trough tank 5, and the outer surface of the hard rubber partitions 6 is tightly fitted with the baffle plate 8. A sealing mechanism is provided between the multi-trough tank 5 and the shell 3. The sealing mechanism includes: a blocking rubber partition 7, which is embedded between the multi-slot tank 5 and the hard rubber partition 6; a rubber plug 9 is inserted into the end of the outer shell 3 away from the sampling port 1, and the rubber plug 9 is engaged with the outer shell 3; the rubber plug 9 is located on one side of the blocking rubber partition 7; a clamping rod 2 is rotatably installed on the outer surface of the sampling port 1, and a time tag 19 is fixedly installed on the outer surface of the clamping rod 2, and a piece of paper is inserted inside the time tag 19; rotating blocks 17 are rotatably installed on both sides of the sampling port 1, and quick-release screws 18 are threaded on the outer surface of the rotating blocks 17; one end of the quick-release screw 18 is engaged with the clamping rod 2, and the outer surface of the clamping rod 2 is in contact with the outer surface of the outer shell 3.

[0022] First, when using the device, simply place the multi-slot bucket 5 and spring 13 inside the outer casing 3, and fix the baffle plate 8 to the side surface of the outer casing 3. Then, place the sealing ring 12 on the outer surface of the sampling port 1. Next, insert the positioning block 14 into the sampling port 1 and turn down the clamping rod 2. Then, rotate the rotating block 17 and insert the quick-release screw 18 into both sides of the clamping rod 2. Press down the quick-release screw 18 to tighten and fix the clamping rod 2. This completes the installation of the sampling device. After that, you can write the initial fermentation time and insert it into the time tag 19. The sampling needle is inserted into the rubber stopper 9 and then into the blocking rubber partition 7 for extraction. Through air pressure and the principle of communicating vessels, the fermentation liquid can enter between the hard rubber partitions 6, allowing the fermentation liquid to be drawn into the syringe. This eliminates the need to frequently open the fermentation tank lid for sampling when needed. At the same time, the multi-tank 5 can be rotated to switch different positions to extract different fermentation liquids at different times, greatly improving the convenience of sampling and reducing the risk of fermentation failure caused by the entry of contaminants into the fermentation tank.

[0023] A sealing ring 12 is placed on one side of the baffle plate 8, and the side surface of the sealing ring 12 is in contact with the outer surface of the outer shell 3 and the outer surface of the baffle plate 8 respectively. The sealing ring 12 is in contact with the outer surface of the sampling port 1. A suction tube 10 is installed through one side of the outer surface of the baffle plate 8, and a filter basket 11 is threaded on the side of the suction tube 10 away from the baffle plate 8. The outer surface of the filter basket 11 is evenly provided with filter holes. The end of the filter basket 11 away from the baffle plate 8 is tapered. A knob 4 is rotatably installed on the outer surface of the outer shell 3, and a groove is provided on the outer surface of the knob 4. An elastic sliding mechanism is provided between the knob 4 and the multi-slot tank 5. The elastic sliding mechanism includes a spring 13. The spring 13 is located inside the multi-slot tank 5, and the multi-slot tank 5 and the knob 4 are respectively inserted into the spring 13. The knob 4 and the multi-slot tank 5 are inserted into each other, and the multi-slot tank 5 and the knob 4 are slidably connected. The knob 4 and the multi-slot tank 5 are concentrically designed.

[0024] Secondly, spring 13 pushes the multi-trough tank 5, allowing the multi-trough tank 5 and the hard rubber partition 6 to fit tightly against the baffle plate 8 and prevent fermentation liquid leakage. After the knob 4 is turned, the multi-trough tank 5 can rotate together, allowing the multi-trough tank 5 to rotate and switch the alignment position with the suction tube 10. At the same time, large debris can be filtered through the filter basket 11, preventing large debris from entering the space between the hard rubber partition 6 through the suction tube 10 and being sucked into the syringe when the fermentation liquid is drawn by the syringe, which would cause the syringe to become blocked and prevent the fermentation liquid from being drawn. This facilitates filtration and prevents blockage, while also making it easy to remove parts such as the sealing ring 12, multi-trough tank 5, and spring 13 for cleaning and disinfection, further improving the convenience of maintenance and cleaning and the accuracy of the sample measurement data.

[0025] The outer casing 3 has time numbers 15 evenly distributed on the side away from the sampling port 1, and the time numbers 15 are aligned with the groove of the knob 4. An elastic positioning mechanism is provided between the knob 4 and the outer casing 3. The elastic positioning mechanism includes a spring piece 16, which is engaged with the outer surface of the knob 4. The outer surface of the outer casing 3 has grooves evenly distributed, and the grooves of the outer casing 3 are engaged with the spring piece 16. A positioning plug 14 is fixedly installed on one side of the outer casing 3, and the positioning plug 14 is engaged with the sampling port 1.

[0026] Furthermore, rotating the knob 4 can drive the multi-slot container 5 to rotate. With the engagement of the spring piece 16 and the outer shell 3, and the alignment of the time number 15, the knob 4, and the spring piece 16, along with the use of the time insert 19, once the time is up, simply rotating the knob will accurately stop the unused hard rubber partition 6 between the rubber stopper 9 and the suction tube 10, achieving mechanical positioning and stopping. This ensures that the currently selected hard rubber partition 6 is precisely aligned with the sampling channel, allowing an unused hard rubber partition 6 to be accurately positioned between the rubber stopper 9 and the suction tube 10, forming a temporary sampling chamber. At this point, a sample can be extracted by piercing the rubber stopper 9 and blocking the rubber partition 7 with a syringe, completing a sterile, accurate, and convenient sampling operation, greatly improving the convenience and accuracy of timing.

[0027] Working principle: When in use, simply insert the multi-trough bucket 5 and spring 13 into the outer shell 3, insert the sealing ring 12 into the sampling port 1, and insert the knob 4 into the multi-trough bucket 5. Then, the outer shell 3 can be positioned by inserting the positioning block 14 into the sampling port 1. Then, turn down the clamping rod 2, and move the rotating block 17 and rotate the quick-release screw 18 so that the quick-release screw 18 can be inserted into both ends of the clamping rod 2. Let the quick-release screw 18 rotate and clamp the clamping rod 2 so that the clamping rod 2 can fix the outer shell 3. Then, write the initial fermentation time on the time plate 19 to complete the installation and preparation of the sampling device. After reaching a specific time point, the sampler arrives at the fermentation tank and inserts the sampling syringe into the rubber stopper 9 and the blocking rubber partition 7 to extract the sample. The fermentation liquid can then be filtered through the filter basket 11 and allowed to enter the chamber formed between the hard rubber partitions 6 through the suction tube 10 and be drawn into the syringe. After the next sampling time is reached, turn knob 4. In conjunction with the use of time number 15, the spring piece 16 engages with the groove of the outer shell 3, allowing the multi-slot tank 5 to rotate. This allows the hard rubber partition 6 to rotate to the clean chamber side where the fermentation liquid has not been sucked. The sampling syringe is then passed through the rubber stopper 9 and the blocking rubber partition 7 again to complete multiple sampling at multiple time points, reducing data errors and fermentation failures caused by bacterial contamination due to multiple openings for sampling.

[0028] 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.
