Description

Technical Field

[0001] The invention belongs to the technical field of fermentation tank sampling, in particular to a beer yeast fermentation tank which is convenient for rapid sampling. Background Art

[0002] In the beer brewing industry, beer fermentation is a core process that determines beer quality and flavor. During the fermentation process, accurate monitoring of the state of materials within the fermentation tank is crucial, and sampling and analysis are the key means to achieve this monitoring. By testing samples from the fermentation tank, brewers can obtain key parameters such as sugar content, alcohol content, pH value, and yeast activity. Based on these parameters, they can determine the fermentation progress and make timely adjustments to the fermentation process to ensure the stable quality and unique flavor of the final beer.

[0003] For example, the invention patent with announcement number CN217265606U discloses a beer yeast fermentation tank that is convenient for rapid sampling, including a device body, a fermentation chamber and a sampling module. The outer wall of the device body is provided with a buffer spring, the fermentation chamber is installed on the side of the buffer spring, the inner wall of the fermentation chamber is provided with an electric control valve, the sampling module is provided on the outer wall of the device body, and an infusion tube is provided inside the sampling module at one end of the electric control valve, and one end of the infusion tube is fixedly connected to a three-way connecting tube. This technology can open the electric control valve and start the pump. The pump absorbs objects in the fermentation chamber through the infusion tube and then discharges them, making it convenient to sample the fermented product. Moreover, the scraper on one side of the stirring rod can be set so that when the stirring rod rotates, the scraper can be driven to slide on the inner wall of the fermentation chamber to clean the inner wall of the fermentation chamber and prevent residues from affecting fermentation.

[0004] In the above technology, although the material in the fermentation tank can be collected, since the collection part is fixed to the side wall of the tank, each sampling can only collect the material near the side wall of the tank.

[0005] According to the GB 4927-2022 "Beer" standard, it is recommended to take samples at 1 / 2 of the vertical height of the tank (≥30 cm from the tank wall). Sampling from the side wall of the tank is not representative due to the physical and chemical gradients and boundary layer effects in the fermentation tank. The fermentation degree in different areas of the tank is different, and the fluid flow rate near the side wall is low and the temperature difference affects yeast activity and product production.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0040] like Figures 1 to 9 As shown, the beer yeast fermentation tank convenient for rapid sampling of the present invention comprises a fermentation part, a control mechanism, a regulating mechanism and an extraction mechanism.

[0041] The fermentation section includes a storage tank 1, a closed end cover 2 and a supporting plate 3. The closed end cover 2 is detachably mounted on the upper end of the storage tank 1. The outer walls of the closed end cover 2 and the storage tank 1 are both provided with flanges to realize the detachable connection between the closed end cover 2 and the storage tank 1. The inner cavity of the storage tank 1 is used to store fermentation materials, and the supporting plate 3 is fixedly mounted on the upper end surface of the closed end cover 2.

[0042] The regulating mechanism is used to regulate the air pressure in the inner cavity of the closed storage tank 1 .

[0043] The control mechanism includes a mounting frame 11, a winding roller 19 and a closing cover 4. The closing cover 4 is detachably mounted on the upper end surface of the supporting plate 3. The bottom of the closing cover 4 is connected to the supporting plate 3 through screws.

[0044] The mounting frame 11 is located in the inner cavity of the closed cover 4 and is fixedly connected to the upper end surface of the supporting plate 3. The winding roller 19 is rotatably arranged on the side wall of the mounting frame 11, wherein the axial ends of the winding roller 19 are rotatably connected to the side walls of the mounting frame 11, and bearings are provided at the connection position.

[0045] The extraction mechanism includes an extraction tube 10 and a counterweight cover 31. One end of the extraction tube 10 passes through the radial outer wall of the winding roller 19 and extends to the center position of the axial end of the winding roller 19. The winding and unwinding of the extraction tube 10 is controlled by rotating the winding roller 19.

[0046] The other end of the extraction pipe 10 extends to the inner cavity of the storage tank 1 and is fixedly connected to the upper end surface of the counterweight cover 31, wherein the radial outer wall of the counterweight cover 31 is provided with a through hole.

[0047] When taking medicine, the extraction tube 10 is unwound by rotating the winding roller 19. In the process of the counterweight cover 31 being immersed in the fermentation flow material, the air inside the counterweight cover 31 is discharged through the through holes on the side wall of the counterweight cover 31 until the counterweight cover 31 extends to the middle of the fermentation material. At this time, the air pressure in the inner cavity of the storage tank 1 is increased by the regulating device. At this time, the material is discharged through the other end of the extraction tube 10, thereby realizing the extraction and sampling of the fermentation material. Compared with the prior art (Chinese patent CN217265606U, a beer yeast fermentation tank that is convenient for rapid sampling), the method of only being able to extract samples at the side wall of the tank body can effectively improve the representativeness of the sampling, so as to improve the accuracy of the subsequent detection and improve the fermentation quality. At the same time, by controlling the unwinding length of the extraction tube 10, sampling can be performed at different depths of the material. After extracting the material, the winding roller 19 is controlled to rotate in the opposite direction to lift the counterweight cover 31.

[0048] As a preferred embodiment of the present invention, the adjustment mechanism includes a storage cylinder 5, an adjustment plug 7 and a control shaft 6. The storage cylinder 5 is fixedly mounted on the upper end surface of the supporting plate 3, and the inner cavity is communicated with the inner cavity of the storage tank 1. The supporting plate 3 provides installation and support for the storage cylinder 5. By adjusting the internal air pressure of the storage cylinder 5, the air pressure in the inner cavity of the storage tank 1 is controlled. Since the inner cavity of the storage cylinder 5 is communicated with the inner cavity of the storage tank 1, no external gas enters the inner cavity of the storage tank 1 during adjustment, thereby preventing external bacteria from entering the inner cavity of the storage tank 1.

[0049] The regulating plug 7 is slidably installed in the inner cavity of the storage cylinder 5, and the radial outer wall is sealed with the inner wall of the storage cylinder 5. The outer wall of the regulating plug 7 is provided with sealing rubber. The air pressure in the inner cavity of the storage cylinder 5 and the storage tank 1 is controlled by sliding the regulating plug 7.

[0050] In order to facilitate the control of the sliding of the regulating plug 7, the control shaft 6 is connected to the upper end surface of the storage tube 5 through internal and external threads. The bottom end of the control shaft 6 extends to the inner cavity of the storage tube 5 and is rotatably connected to the upper end surface of the regulating plug 7 through a bearing. By rotating the control shaft 6, the regulating plug 7 is driven to slide along the inner cavity of the storage tube 5 to achieve air pressure regulation.

[0051] When extracting a sample, firstly lower the weight cover 31 to the desired position, and then lower the regulating plug 7 to discharge the fermentation material from the extraction tube 10, thereby achieving sample collection of the fermentation flow.

[0052] A control box 9 is fixedly installed on the side wall of the mounting frame 11, and a transmission shaft 14 is rotatably installed in the inner cavity of the control box 9, wherein the axial end of the transmission shaft 14 is fixedly connected to one axial end of the winding roller 19. Rotating the transmission shaft 14 drives the winding roller 19 to rotate, which is used to control the winding and unwinding of the extraction tube 10.

[0053] A transmission worm gear 16 is fixedly mounted on the radial outer wall of the transmission shaft 14, and a transmission worm 15 meshing with the transmission worm gear 16 is rotatably mounted on the inner wall of the control box 9. A control motor 8 for controlling the rotation of the transmission worm gear 15 is fixedly mounted on the outer wall of the control box 9. The rotation of the transmission worm gear 15 is controlled by the control motor 8, thereby controlling the rotation of the transmission worm gear 16 and the transmission shaft 14.

[0054] In this embodiment, the transmission worm 15 and the transmission worm wheel 16 cooperate to control the rotation of the winding roller 19, and utilize the unidirectionality of the transmission to prevent the counterweight cover 31 from falling naturally.

[0055] As a preferred embodiment of the present invention, a transfer block 20 is fixedly mounted on the inner wall of the sealing cover 4 , and a three-way cavity is opened on the inner wall of the transfer block 20 .

[0056] One end of the adapter block 20 is connected to the extraction tube 10 at the axial end of the winding roller 19 through a sealed bearing, so that the sealing connection between the extraction tube 10 and the adapter block 20 is maintained when the winding roller 19 rotates.

[0057] When sampling, a negative pressure bottle is required. A loading tube 25 is fixedly installed on the other end of the adapter block 20. One end of the loading tube 25 extends to the outer wall of the closing cover 4. When the sample flows in the extraction tube 10, the negative pressure bottle is connected to the loading tube 25 until the sample flows into the inner cavity of the negative pressure bottle. Then the loading tube 25 is closed and the negative pressure bottle is taken out to realize the extraction of the sample.

[0058] A choke 26 is fixedly mounted on the inner wall of the loading tube 25 . A truncated cone-shaped through hole is defined inside the choke 26 . The bottom of the truncated cone-shaped through hole faces the top of the adapter block 20 and the loading tube 25 .

[0059] A transmission frame 24 is elastically mounted on the inner wall of the loading tube 25. A closing plug 23 that cooperates with the truncated cone-shaped through hole is fixedly mounted on one end of the transmission frame 24 close to the adapter block 20. A spring is provided on the outer wall of the transmission frame 24. The other end of the spring is fixedly connected to the outer wall of the choke plug 26. The elastic force of the spring drives the transmission frame 24 and the closing plug 23, so that the closing plug 23 has a tendency to close the choke plug 26 in real time.

[0060] During the process of plugging the negative pressure bottle and the loading tube 25, the transmission frame 24 is pushed through the bottle mouth until the closing plug 23 is separated from the blocking plug 26. At this time, the liquid on the inner wall of the extraction tube 10 flows out. After the extraction is completed, the negative pressure bottle is pulled out. As the bottle mouth and the transmission frame 24 are separated, the elastic force pushes the transmission frame 24 to close the blocking plug 26 again, thereby realizing the automatic closure of the loading tube 25.

[0061] As a preferred embodiment of the present invention, a control cylinder 12 is fixedly mounted on the inner wall of the sealing cover 4 , a control pile 27 is slidably mounted on the inner wall of the control cylinder 12 , and the outer wall of the control pile 27 is sealed and fitted with the inner wall of the control cylinder 12 .

[0062] A groove is formed at the bottom of the control pile 27 and a balance hole 29 is formed at the upper end surface of the control pile 27 so as to maintain the air pressure balance on both sides of the control pile 27 when the control pile 27 slides along the inner cavity of the control cylinder 12.

[0063] The inner cavity of the control cylinder 12 is connected to the inner cavity of the adapter block 20. The outer wall of the control cylinder 12 is provided with a vent pipe 21 and a buffer cylinder 13, and the connection position of the buffer cylinder 13 is located between the connection position of the control cylinder 12 and the connection position of the adapter block 20 (such as Figure 6 shown).

[0064] When adjusting and increasing the air pressure in the inner cavity of the storage tank 1, the air inside the extraction tube 10 is first discharged. At this time, it is necessary to slide the control pile 27 until the groove at the bottom of the control pile 27 connects the adapter block 20 and the cache tube 13. At this time, the air inside the extraction tube 10 enters the inner cavity of the cache tube 13, until the liquid level inside the extraction tube 10 is close to the adapter block 20, slide the control pile 27 until the groove at the bottom of the control pile 27 connects the cache tube 13 and the air release pipe 21. At this time, the connection position of the control tube 12 and the adapter block 20 is blocked by the outer wall of the control pile 27, and the internal gas of the cache tube 13 enters the inner cavity of the air release pipe 21 through the groove at the bottom of the control pile 27 and is discharged. At the same time, the negative pressure bottle is connected to the loading tube 25 to hold the material to prevent excessive air from entering the interior of the negative pressure bottle and maintain the quality of sampling.

[0065] A pressure relief hole is provided at one end of the cache cylinder 13 away from the control cylinder 12. A sliding plug 28 is elastically installed in the inner cavity of the cache cylinder 13. The sliding plug 28 is connected to the inner wall of the control cylinder 12 through a spring. The pressure relief hole is provided to maintain the air pressure balance on one side of the sliding plug 28 during the sliding process of the sliding plug 28.

[0066] When the air inside the extraction tube 10 is injected into the inner cavity of the buffer tube 13, the sliding plug 28 slides. When the buffer tube 13 is connected to the vent tube 21, the spring pushes the sliding plug 28 to slide, and the air inside is automatically discharged.

[0067] In order to facilitate the sliding adjustment of the control pile 27, an adjustment shaft 22 is fixedly installed at one axial end of the control pile 27. The adjustment shaft 22 passes through the control cylinder 12 and slides in contact with the inner wall of the control cylinder 12. The adjustment shaft 22 extends to the outer wall of the closed cover 4, and a seal needs to be provided at the connection position. The control pile 27 is driven to slide and adjust by sliding the adjustment shaft 22.

[0068] As a preferred embodiment of the present invention, a conical cover 32 is fixedly mounted on the bottom surface of the supporting plate 3 , with the tip of the conical cover 32 facing downward.

[0069] A mounting ring 30 is provided at the bottom of the conical cover 32, and a connecting rod 33 is rotatably installed on the upper end surface of the mounting ring 30. The other end of the connecting rod 33 is detachably connected to the outer wall of the conical cover 32. The connecting rod 33 is connected to the conical cover 32 by threaded fitting. After assembly, the mounting ring 30 is located below the tip of the conical cover 32.

[0070] A wiping layer 34 is fixedly mounted on the inner wall of the mounting ring 30 , and the wiping layer 34 is made of a common sponge material.

[0071] The extraction tube 10 passes through the wiping layer 34 , and the outer wall thereof slides in contact with the inner wall of the wiping layer 34 . After the fermentation material enters the extraction tube 10 , the outer wall thereof will stick to the material. When the extraction tube 10 is rolled up, the sticky matter on the outer wall of the extraction tube 10 is wiped off by the wiping layer 34 , thereby keeping the outer wall of the extraction tube 10 clean.

[0072] During the fermentation process, water droplets condense on the outer wall of the conical cover 32 and slide downwardly due to gravity until they fall onto the wiping layer 34 inside the mounting ring 30 , thereby wetting the wiping layer 34 and improving the quality of wiping and cleaning the surface of the extraction tube 10 .

[0073] A mounting cover 17 is fixedly mounted on the outer wall of the mounting frame 11 , and a cavity is provided inside the mounting cover 17 .

[0074] A sector gear 36 is rotatably mounted on the inner wall of the mounting cover 17. The transmission shaft 14 passes through the mounting cover 17 and controls the rotation of the sector gear 36 through a transmission member. The transmission member is a belt and a pulley. During the rotation of the transmission shaft 14, the rotation of the sector gear 36 is controlled by the cooperation of the belt and the pulley.

[0075] A transmission tooth plate 35 is elastically mounted on the inner wall of the mounting cover 17 , and a knocking block 18 for knocking the conical cover 32 is fixedly mounted on the bottom of the transmission tooth plate 35 , wherein the sector gear 36 is meshed with the transmission tooth plate 35 .

[0076] When the sector gear 36 contacts the transmission tooth plate 35, it drives the transmission tooth plate 35 to slide until the sector gear 36 separates from the transmission tooth plate 35. At this time, the transmission tooth plate 35 is controlled to slide in the opposite direction by elastic force, and the knocking block 18 is controlled by inertia to knock on the conical cover 32, causing the conical cover 32 to vibrate, so that the attached water droplets can slide off.
