Description

Technical Field

[0001] The present invention belongs to the technical field of fermentation tank sampling, and specifically relates to a beer yeast fermentation tank that facilitates rapid sampling. Background Art

[0002] In the beer brewing industry, beer fermentation is the core link that determines the quality and flavor of beer. During the fermentation process, accurate monitoring of the material state in the fermentation tank is crucial, and sampling analysis is the key means to achieve this monitoring. By detecting the samples in the fermentation tank, brewers can obtain key parameters such as sugar content, alcohol content, pH value, and yeast activity, and then judge the fermentation process based on these parameters, and timely adjust the fermentation process to ensure the stable quality and unique flavor of the final beer product.

[0003] For example, the invention patent with the publication number CN217265606U discloses a beer yeast fermentation tank that facilitates rapid sampling, including a device main body, a fermentation chamber, and a sampling module. A buffer spring is arranged on the outer wall of the device main body, the fermentation chamber is installed on the side of the buffer spring, an electric control valve is arranged on the inner wall of the fermentation chamber, the sampling module is arranged on the outer wall of the device main body, an infusion pipe is arranged at one end inside the sampling module and located at one end of the electric control valve, and one end of the infusion pipe is fixedly connected with a three-way connecting pipe. With this technology, by opening the electric control valve and starting the pump, the pump can adsorb the objects in the fermentation chamber through the infusion pipe and then discharge them, which is convenient for sampling the fermented substances. And through the setting of the scraping plate on one side of the stirring rod, when the stirring rod rotates, it can drive the scraping plate to slide on the inner wall of the fermentation chamber to clean the inner wall of the fermentation chamber and avoid the influence of residues on fermentation.

[0004] In the above technology, although the collection of materials in the fermentation tank can be achieved, since the collection position is fixed on the side wall of the tank body, only the materials near the side wall of the tank body can be collected each time.

[0005] According to the GB 4927-2022 "Beer" standard, it is recommended to take samples at the 1 / 2 vertical height of the tank body (≥30 cm from the tank wall). Sampling from the side wall of the tank body makes the samples unrepresentative due to the physical and chemical gradients and boundary layer effects in the fermentation tank. The fermentation degrees in different areas of the tank are different, and the low fluid velocity and temperature differences near the side wall affect yeast activity and product formation.

DETAILED DESCRIPTION OF THE INVENTION

[0039] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0040] As Figures 1 to 9 shown, a beer yeast fermenter facilitating rapid sampling according to the present invention includes a fermentation part, a control mechanism, an adjustment mechanism and an extraction mechanism.

[0041] The fermentation part includes a storage tank 1, a closed end cover 2 and a bearing plate 3. The closed end cover 2 is detachably installed at the upper end of the storage tank 1. Flange plates are provided on the outer walls of both the closed end cover 2 and the storage tank 1 to achieve the detachable connection between the closed end cover 2 and the storage tank 1. The inner cavity of the storage tank 1 is used for storing fermentation materials. The bearing plate 3 is fixedly installed on the upper end surface of the closed end cover 2.

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

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

[0044] The mounting frame 11 is located inside the closed cover 4 and is fixedly connected to the upper end surface of the bearing plate 3. The winding roller 19 is rotatably arranged on the side wall of the mounting frame 11. Among them, the axial two ends of the winding roller 19 are rotatably connected to the side wall of the mounting frame 11, and bearings are provided at the connection positions.

[0045] The extraction mechanism includes an extraction pipe 10 and a counterweight cover 31. One end of the extraction pipe 10 penetrates 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 pipe 10 are controlled by rotating the winding roller 19.

[0046] The other end of the extraction pipe 10 extends into the inner cavity of the storage tank 1 and is fixedly connected to the upper end surface of the counterweight cover 31. Among them, through holes are provided on the radial outer wall of the counterweight cover 31.

[0047] When taking medicine, the extraction tube 10 is unwound by rotating the winding roller 19. During the process of the counterweight cover 31 being immersed in the fermented 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 fermented material. At this time, the air pressure inside the storage tank 1 is increased by the adjusting device, and the material is discharged from the other end of the extraction tube 10, thereby realizing the extraction and sampling of the fermented material. Compared with the prior art (Chinese Patent CN217265606U, a beer yeast fermenter facilitating rapid sampling), in which samples can only be extracted at the side wall position of the tank body, the representativeness of sampling can be effectively improved, so as to improve the fermentation quality by enhancing the accuracy of later detection. At the same time, by controlling the unwinding length of the extraction tube 10, sampling can be carried out at different depths of the material. After extracting the material, the winding roller 19 is rotated in the reverse direction to lift the counterweight cover 31 out.

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

[0049] The adjusting plug 7 is slidably installed in the inner cavity of the storage cylinder 5, and its radial outer wall is in sealing fit with the inner wall of the storage cylinder 5. A sealing rubber is provided on the outer wall of the adjusting plug 7. By sliding the adjusting plug 7, the air pressure inside the storage cylinder 5 and the storage tank 1 is controlled.

[0050] To facilitate the control of the sliding of the adjusting plug 7, the control shaft 6 is connected to the upper end surface of the storage cylinder 5 through internal and external thread cooperation. The bottom end of the control shaft 6 extends into the inner cavity of the storage cylinder 5 and is rotatably connected to the upper end surface of the adjusting plug 7 through a bearing. By rotating the control shaft 6, the adjusting plug 7 is driven to slide along the inner cavity of the storage cylinder 5 to achieve air pressure adjustment.

[0051] When extracting a sample, first lower the counterweight cover 31 to the required position, and then discharge the fermented material from the extraction tube 10 by sliding down the adjusting plug 7 to achieve the sample collection of the fermented material flow.

[0052] A control box 9 is fixedly installed on the side wall of the mounting frame 11. A transmission shaft 14 is rotatably installed in the inner cavity of the control box 9. Among them, 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 for controlling the winding and unwinding of the extraction tube 10.

[0053] A drive worm wheel 16 is fixedly installed on the radially outer wall of a drive shaft 14. A drive worm 15 that meshes with the drive worm wheel 16 is rotatably installed on the inner wall of a control box 9. A control motor 8 for controlling the rotation of the drive worm 15 is fixedly installed on the outer wall of the control box 9. By controlling the rotation of the drive worm 15 with the control motor 8, the rotation of the drive worm wheel 16 and the drive shaft 14 is controlled.

[0054] In this embodiment, the rotation of a take-up roller 19 is controlled by the cooperation of the drive worm 15 and the drive worm wheel 16, and the natural fall of a counterweight cover 31 is prevented by the unidirectionality of their transmission.

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

[0056] One end of the transfer block 20 is connected to an extraction pipe 10 at the axial end of the take-up roller 19 through a sealing bearing, so that when the take-up roller 19 rotates, a sealed connection between the extraction pipe 10 and the transfer block 20 is maintained.

[0057] During sampling, a negative pressure bottle is required. The other end of the transfer block 20 is fixedly installed with a loading pipe 25. One end of the loading pipe 25 extends to the outer wall of the closed cover 4. When the sample flows in the extraction pipe 10, the negative pressure bottle is connected to the loading pipe 25 until the sample flows into the inner cavity of the negative pressure bottle, and then the loading pipe 25 is closed and the negative pressure bottle is taken out to complete the extraction of the sample.

[0058] A flow blocking plug 26 is fixedly installed on the inner wall of the loading pipe 25. A frustum-shaped through hole is provided inside the flow blocking plug 26, and the bottom of the frustum-shaped through hole faces the top of the transfer block 20 and the loading pipe 25.

[0059] A transmission frame 24 is elastically installed on the inner wall of the loading pipe 25. A closing plug 23 that cooperates with the frustum-shaped through hole is fixedly installed at one end of the transmission frame 24 close to the transfer block 20. A spring is provided on the outer wall of the transmission frame 24, and the other end of the spring is fixedly connected to the outer wall of the flow blocking plug 26. The transmission frame 24 and the closing plug 23 are driven by the elastic force of the spring, so that the closing plug 23 always has a tendency to close the flow blocking plug 26.

[0060] During the insertion process of the negative pressure bottle into the loading pipe 25, the transmission frame 24 is pushed by the bottle mouth until the closing plug 23 is separated from the flow blocking plug 26. At this time, the liquid on the inner wall of the extraction pipe 10 flows out. After the extraction is completed, the negative pressure bottle is pulled out. As the bottle mouth is separated from the transmission frame 24, the transmission frame 24 is pushed by the elastic force at this time to close the flow blocking plug 26 again, realizing the automatic closing of the loading pipe 25.

[0061] As a preferred embodiment of the present invention, a control cylinder 12 is fixedly installed on the inner wall of the closed cover 4. A control post 27 is slidably installed on the inner wall of the control cylinder 12, and the outer wall of the control post 27 is in sealing fit with the inner wall of the control cylinder 12.

[0062] A groove is provided at the bottom of the control pile 27, and a balance hole 29 is provided on the upper end surface of the control pile 27, so as to keep the air pressure balanced 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 communicates with the inner cavity of the adapter block 20. An air discharge pipe 21 and a buffer cylinder 13 are provided on the outer wall of the control cylinder 12, 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 (as Figure 6 shown).

[0064] When adjusting and increasing the air pressure in the inner cavity of the storage tank 1, first, the air inside the extraction pipe 10 is discharged. At this time, it is necessary to slide the control pile 27 until the groove at the bottom of the control pile 27 communicates with the adapter block 20 and the buffer cylinder 13. At this time, the air inside the extraction pipe 10 enters the inner cavity of the buffer cylinder 13. When the liquid level inside the extraction pipe 10 approaches the adapter block 20, slide the control pile 27 until the groove at the bottom of the control pile 27 communicates with the buffer cylinder 13 and the air discharge pipe 21. At this time, the connection position between the control cylinder 12 and the adapter block 20 is blocked by the outer wall of the control pile 27. The gas inside the buffer cylinder 13 enters the inner cavity of the air discharge pipe 21 through the groove at the bottom of the control pile 27 and is discharged. At the same time, connect the negative pressure bottle to the loading pipe 25 to receive the material, prevent too much air from entering the inside of the negative pressure bottle, and maintain the quality of the sampling.

[0065] A pressure relief hole is provided at one end of the buffer cylinder 13 away from the control cylinder 12. A sliding plug 28 is elastically installed in the inner cavity of the buffer 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 keep the air pressure balanced on one side of the sliding plug 28 during the sliding process of the sliding plug 28.

[0066] When the air inside the extraction pipe 10 is injected into the inner cavity of the buffer cylinder 13, the sliding plug 28 slides. When the buffer cylinder 13 communicates with the air discharge pipe 21, the spring pushes the sliding plug 28 to slide and automatically discharges the internal air.

[0067] 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 penetrates through the control cylinder 12 and is slidably fitted 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 slidably adjusted by sliding the adjustment shaft 22.

[0068] As a preferred embodiment of the present invention, a conical cover 32 is fixedly installed on the bottom surface of the bearing plate 3, and the tip of the conical cover 32 is arranged downward.

[0069] The bottom of the conical cover 32 is provided with a mounting ring 30. The upper end face of the mounting ring 30 is rotatably mounted with a connecting rod 33. 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 screw fit. After assembly, the mounting ring 30 is located below the tip of the conical cover 32.

[0070] The inner wall of the mounting ring 30 is fixedly mounted with a wiping layer 34. 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 is slidably fitted with the inner wall of the wiping layer 34. After the extraction tube 10 enters the fermentation material, the outer wall will adhere to the material. When the extraction tube 10 is wound up, the adhesive on the outer wall of the extraction tube 10 is wiped by the wiping layer 34 to keep 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. The water droplets slide downward to the tip due to gravity until they drip onto the wiping layer 34 in 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] The outer wall of the mounting frame 11 is fixedly mounted with a mounting cover 17. 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 through 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. A knocking block 18 for knocking the conical cover 32 is fixedly mounted at the bottom of the transmission tooth plate 35. The sector gear 36 and the transmission tooth plate 35 are meshed.

[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 is separated from the transmission tooth plate 35. At this time, the transmission tooth plate 35 slides reversely through the elastic force, and the knocking block 18 is controlled by inertia to knock the conical cover 32, causing the conical cover 32 to vibrate so that the attached water droplets can slide off.

[0077] The above front, back, left, right, up, and down are all based on Figure 1 the description in the attached drawings of the specification. Taking the observer's perspective as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
