Description

Technical Field

[0001] This utility model belongs to the technical field of saccharification equipment, and in particular relates to a water bath saccharification pot. Background Technology

[0002] In brewing, saccharification refers to the process of mixing yeast or saccharifying agent with raw materials and fermenting them in a saccharification pot at a suitable temperature and humidity to break down polysaccharides in the raw materials into monosaccharides.

[0003] An example of existing technology is an automated beer brewing wort preparation device disclosed in Chinese Patent (CN207031402U). This device includes: a water bath container for holding heated water; a saccharification container for holding ground malt and the heated water in the water bath container to achieve saccharification and wort filtration; a first transfer pipeline for transferring the heated water in the water bath container to the saccharification container; a first circulation pipeline for self-circulation of the liquid in the saccharification container, the circulation pipeline including a heat exchange pipeline located within the water bath container; a boiling container for receiving the liquid in the saccharification container and boiling it; a second transfer pipeline for transferring the liquid in the saccharification container to the boiling container; a second circulation pipeline for self-circulation of the liquid in the boiling container; an output pipeline for outputting the liquid from the boiling container; and a controller for controlling the flow and shut-off of the pipelines and the heating of the liquid in the water bath container and the boiling container.

[0004] This method has the following drawbacks: First, during the saccharification process, workshop workers need to take samples out through sampling tubes for observation. This sampling method wastes some raw materials, and the pressure of the raw materials can also cause splashing and burns to the samplers. Second, the raw materials inside the saccharification container will produce some residue after saccharification. If this residue is discharged directly from the discharge pipe, it will cause blockage of the discharge pipe. At the same time, the residue accumulation at the inlet of the discharge pipe will reduce the discharge efficiency of the slurry. Third, the stirring rod in the saccharification tank stirs the materials during the saccharification process to make the materials heat and mix evenly. However, after the materials are discharged, the residue in the fermentation liquid will adhere to the stirring rod. The fermentation liquid cannot be discharged smoothly. After the water vapor in the tank is evaporated by the high temperature, the residue will also be evaporated and adhere to the stirring rod. In this way, the dried residue on the stirring rod is not easy to remove during the subsequent cleaning process, which increases the time required to clean the stirring rod.

[0005] Therefore, this utility model provides a water bath saccharification pot. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: First, during the saccharification process, workshop workers need to take out samples for observation through sampling tubes. This sampling method wastes some raw materials, and the raw materials being squeezed out under pressure also pose a risk of splashing and burning the samplers; Second, the raw materials inside the saccharification container will produce some residue after saccharification. If this residue is discharged directly from the discharge pipe, it will cause blockage of the discharge pipe. At the same time, the residue accumulating at the inlet of the discharge pipe will reduce the discharge efficiency of the slurry; Third, the stirring rod in the saccharification tank stirs the materials during the saccharification process, so that the materials are heated and mixed evenly. However, after the materials are discharged, the residue in the fermentation liquid will adhere to the stirring rod. The fermentation liquid cannot be discharged smoothly after discharge. After the water vapor in the tank is evaporated by the high temperature, the residue will also be evaporated and adhere to the stirring rod. In this way, the dry residue on the stirring rod is not easy to clean off during the subsequent cleaning process, which increases the time required to clean the stirring rod; Example 1

[0026] like Figures 1 to 4 As shown:

[0027] Therefore, the inventor provides a water bath saccharification pot, including an inner liner 1, a water bath layer 2, a stirring mechanism, a feed pipe 3, a pressure sensor 4, an exhaust pipe 5, a discharge pipe 6, and a temperature sensor 7. The water bath layer 2 is located on the outside of the inner liner 1. The stirring mechanism passes through the inner liner 1 and is located in the middle of the inner liner 1. The feed pipe 3 is located on the upper left side of the inner liner 1. The pressure sensor 4 is located on the right side of the feed inlet. The exhaust pipe 5 is located in front of the pressure sensor 4. The discharge pipe 6 is located below the inner liner 1. The temperature sensor 7 is located on the right side of both the inner liner 1 and the water bath layer 2. The stirring mechanism, pressure sensor 4, and temperature sensor 7 are connected to the workshop control cabinet (…). Telecommunications connection between (not shown in the figure) and; a sampling and observation mechanism is also provided on the front side of the inner liner 1, and the sampling and observation mechanism is telecommunicationly connected to the production workshop control cabinet; the stirring mechanism also includes a drive motor a8, a transmission mechanism 9, a stirring rod 10, and a sleeve 11. The drive motor a8 is located below the inner liner 1, the transmission mechanism 9 is located on the output end above the drive motor, the stirring rod 10 is located on the side of the transmission mechanism 9, and the sleeve 11 is located on the outside of the transmission mechanism 9 and is rotatably connected to the inner liner 1 in a sealed manner; a filter mechanism is also provided at the end of the discharge pipe 6, and the filter mechanism is telecommunicationly connected to the production workshop control cabinet.

[0028] Using the above scheme, the mixed raw materials are discharged into the inner tank 1 through the feed pipe 3, and then hot water is introduced into the water bath layer 2 to heat the raw materials in the inner tank 1. At the same time, the temperature sensor 7 is set to detect the temperature of the inner tank 1 and the water bath layer 2 in real time to control the temperature of the input hot water, so as to maintain a stable fermentation temperature inside the inner tank 1. The pressure sensor 4 detects the pressure inside the inner tank 1. When the pressure exceeds the set value, the control cabinet automatically controls the opening of the exhaust pipe 5 to release gas and maintain stability. During the fermentation process, the drive motor a8 drives the transmission device to stir the material inside the inner tank 1 with the stirring rod 10 and the sleeve 11 to ensure the efficiency of fermentation. During the fermentation and saccharification process, the internal fermentation situation can be observed by opening the sampling and observation mechanism, and samples can be taken at the same time. After the sampling and observation are completed, the observed liquid can be returned to the device. After the saccharification and fermentation are completed, the fermentation liquid is discharged from the discharge pipe 6. After the impurities are filtered out by the filtration mechanism, the pure fermentation liquid after saccharification is obtained. Example 2

[0029] like Figures 1 to 4 As shown:

[0030] Furthermore, the sampling and observation mechanism also includes a connecting pipe 12, an electric valve a13, an observation pipe 14, an electric valve b15, a U-shaped pipe 16, an electric valve c17, an electric valve d18, and a return pipe 19. The connecting pipe 12 is located on the front side of the inner tank 1 and extends through the water bath layer 2. The electric valves a13 are respectively located on the connecting pipe 12. The observation pipe 14 is located between the connecting pipes 12 and its upper and lower ends are connected to the connecting pipes 12. The electric valve b15 is located at the lower end of the observation pipe 14. The U-shaped pipe 16 is located at the lower end of the electric valve b15. The other end of the U-shaped pipe 16 is equipped with an electric valve d18 and is connected to the steam branch pipe of the production workshop. The electric valve c17 is located at the upper end of the observation pipe 14. The return pipe 19 is located at the upper end of the electric valve c17 and its end is connected to the top of the inner tank 1.

[0031] Furthermore, a protective plate 20 and a protective rod 21 are also provided on the outside of the observation tube 14. The protective plate 20 is respectively provided at the upper and lower ends of the observation tube 14, and the protective rod 21 is provided between the protective plates 20 by bolts.

[0032] Furthermore, a sampling tube 22 and a needle valve 23 are also provided on the right side of the U-shaped tube 16. The sampling tube 22 is located on the right side of the U-shaped tube 16, and the needle valve 23 is located on the sampling tube 22.

[0033] During the raw material fermentation and saccharification process, the sampler controls the electric valve a13 to open via the workshop control cabinet, connecting the inner liner 1 and the observation tube 14 via the connecting pipe 12. This allows the fermentation liquid inside the inner liner 1 to enter the observation tube 14, which is made of high-temperature resistant borosilicate glass. The sampler can clearly observe the fermentation process of the raw materials. The side of the observation tube 14 is equipped with a protective rod 21 via a protective plate 20 to prevent it from being broken. If sampling is required during the observation process, the electric valve a13 is closed and the electric valve c17 is opened via the workshop control cabinet, allowing the sampling liquid to enter the U-shaped tube. In section 16, the U-shaped tube 16 can act as a buffer to reduce pressure. At the same time, the sampler can open the needle valve 23 on the side of the U-shaped tube 16 to allow the fermentation liquid to be discharged from the sampling tube 22 for sampling. In this way, the depressurized liquid will not spray out during sampling, causing scalding. After sampling, the needle valve 23 is closed, and the electric valves b15 and d18 are opened to allow the pressurized steam from the production workshop to enter the U-shaped tube from the steam branch pipe, pushing the liquid in the tube upward back into the observation tube 14. Then, it is pushed back into the inner tank 1 through the return pipe 19 for saccharification and fermentation, saving raw materials. Example 3

[0034] like Figures 1 to 4 As shown:

[0035] Furthermore, the transmission mechanism 9 also includes a plug rod 24, a sleeve rod 25, a spiral blade 26, a lower sleeve 27, a limiting rod 28, a connecting rod 29, an upper sleeve 30, and a spring 31. The plug rod 24 is located above the output end of the drive motor a8. The sleeve rod 25 is located above the plug rod 24 and its lower end is slidably connected to the plug rod 24 through a slot. The spiral blade 26 is located on the outside of the sleeve rod 25. The lower sleeve 27 is located below the inner liner 1 on the side of the spiral blade 26. The limiting rod 28 is located inside the lower sleeve 27. The connecting rod 29 is located above the sleeve rod 25 and extends out of the inner liner 1 through the sleeve 11. The upper sleeve 30 is located above the inner liner 1. The spring 31 is located between the upper end of the connecting rod 29 and the inside of the upper sleeve 30. The upper end of the connecting rod 29 is provided with a rotating shaft that is rotatably connected to the connecting rod 29.

[0036] Furthermore, a gap is provided between the upper ends of the spiral blades 26 for the limiting rod 28 to pass through;

[0037] Furthermore, the side of the connecting rod 29 is provided with a mounting hole and is connected to the stirring rod 10 via a ball joint transmission;

[0038] Furthermore, a sealing rubber cone 32 is provided at the connection between the stirring rod 10 and the sleeve 11;

[0039] During the fermentation process of the raw materials inside the inner liner 1, the drive motor a8 drives the sleeve rod 25 to rotate via the insertion rod 24, causing the connecting rod 29 to drive the stirring rod 10 and the sleeve 11 to rotate inside the inner liner 1, stirring and mixing the fermentation liquid inside the inner liner 1 to enhance the fermentation effect. While stirring, the spiral blade 26 is rotating and is restricted by the limiting rod 28 on the inner side of the lower sleeve 27, causing the sleeve rod 25 to drive the connecting rod 29 to be lifted upward. During the upward rotation of the connecting rod 29, the upper end of the connecting rod 29 compresses the spring 31 inside the upper sleeve 30, and the rotating shaft above the connecting rod 29 rotates below the spring 31 to ensure the normal operation of the mechanism. At the same time, the connection between the side stirring rod 10 and the connecting rod 29 is raised, and the stirring rod 10 on the outside of the sleeve 11 is pressed downward. When the limiting rod 28 reaches the spiral blade 26... At the bottom of position 6, the limiting rod 28 disengages from the gap of the spiral blade 26, and the spiral blade 26 loses its limiting function. The spring 31 in the upper sleeve 30 presses down the connecting rod 29, causing the sleeve rod 25 to return to its initial position. The limiting rod 28 returns to the lower part of the upper end of the spiral blade 26. This reciprocating motion allows the stirring rod 10 to shake downwards during rotation within the sleeve 11, increasing the stirring effect and shaking off the residue adhering to the surface of the stirring rod 10. This reduces the adhesion of residue to the surface of the stirring rod 10, reduces the cleaning burden on the stirring rod 10 during subsequent cleaning, and reduces the cleaning time of the stirring rod 10. During the stirring process, the insert rod 24 is inserted into the sleeve rod 25 through the cross insert plate, causing the sleeve rod 25 and the connecting rod 29 to rotate, while the sleeve rod 25 can slide up and down above the insert rod 24. Example 4

[0040] like Figures 1 to 4 As shown:

[0041] Furthermore, the filtration mechanism also includes a filter cylinder 33, a filter plate 34, a cylinder cover 35, a drive motor b36, a stirring blade 37, and a liquid outlet pipe 38. The filter cylinder 33 is located on the right side of the discharge pipe 6 and is connected to the inlet on the upper left side of the filter cylinder 33. The filter plate 34 is located inside the filter cylinder 33. The cylinder cover 35 is located above the filter cylinder 33 and is hinged to the filter cylinder 33. The drive motor b36 is located above the cylinder cover 35. The output end of the drive motor b36 passes through the cylinder cover 35 and enters the interior of the filter cylinder 33. The stirring blade 37 is located on the side of the output end below the drive motor b36. The liquid outlet pipe 38 is located on the lower right side of the filter cylinder 33.

[0042] The fermentation liquid after saccharification and fermentation enters the filter cylinder 33 through the discharge pipe 6. After being filtered by the filter plate 34, the filtrate flows downward through the discharge pipe 38. During the filtration process, the drive motor b36 drives the stirring blade 37 to rotate on the filter plate 34, stirring the liquid to increase the filtration effect. The filtered residue remains above the filter plate 34. After filtration is completed, the cylinder cover 35 is opened to clean the residue inside the filter plate 34 and the stirring rod 10. Because the discharge pipe 38 uses a larger diameter pipe and the filtration function is set in the filter cylinder 33, which is shorter and wider than the saccharification pot, it prevents the residue from causing blockage in the saccharification pot, improves the efficiency of discharging the fermentation liquid, and facilitates the subsequent cleaning of the residue.

[0043] In summary, the device incorporates a sampling and observation mechanism to prevent splashing and burns during sampling. After sampling and observation, the solution is re-pressed into the inner tank 1 for saccharification and fermentation, saving raw materials. It also includes a drive motor a8, a transmission mechanism 9, a stirring rod 10, and a sleeve 11, which enhance the stirring effect while shaking off residue adhering to the surface of the stirring rod 10, reducing residue adhesion and the cleaning burden and time required for subsequent cleaning. Finally, a filtration mechanism prevents residue from clogging the saccharification pot, improving the efficiency of discharging the fermentation liquid and facilitating subsequent residue cleaning.

[0044] The working principle of this utility model:

[0045] The mixed raw materials are discharged into the inner tank 1 through the feed pipe 3. Then, hot water is introduced into the water bath 2 to heat the raw materials in the inner tank 1. At the same time, the temperature sensor 7 is set to detect the temperature of the inner tank 1 and the water bath 2 in real time to control the temperature of the hot water input, so that the fermentation temperature inside the inner tank 1 is maintained stably. The pressure sensor 4 detects the pressure inside the inner tank 1. When the pressure exceeds the set value, the control cabinet automatically controls the opening of the exhaust pipe 5 to release gas and maintain stability. The pressure sensor can be a digital pressure gauge, which is convenient for local reading and can also transmit pressure signals.

[0046] During fermentation, the sampler opens electric valve a13 via the workshop control cabinet, connecting pipe 12 to the inner tank 1 and observation tube 14, allowing the fermentation liquid inside the inner tank 1 to enter the observation tube 14. The observation tube 14 is made of high-temperature resistant borosilicate glass, allowing the sampler to clearly observe the fermentation process. A protective rod 21 is installed on the side of the observation tube 14 via a protective plate 20 to prevent breakage. If sampling is required during observation, electric valve a13 is closed and electric valve c17 is opened via the workshop control cabinet, allowing the sampling liquid to enter the U-shaped tube 16. The U-shaped tube 16 can act as a buffer to reduce pressure. At the same time, the sampler can open the needle valve 23 on the side of the U-shaped tube 16 to allow the fermentation liquid to be discharged from the sampling tube 22 for sampling. In this way, the depressurized liquid will not spray out during sampling, causing splashing and scalding. After sampling, the needle valve 23 is closed and the electric valves b15 and d18 are opened to allow the pressurized steam from the production workshop to enter the U-shaped tube from the steam branch pipe, pushing the liquid in the tube upward back into the observation tube 14. Then, it is pushed back into the inner tank 1 through the return pipe 19 for saccharification and fermentation, saving raw materials.

[0047] Simultaneously, the drive motor a8 drives the sleeve rod 25 to rotate via the insertion rod 24, causing the connecting rod 29 to drive the stirring rod 10 and the sleeve 11 to rotate inside the inner liner 1, stirring and mixing the fermentation liquid inside the inner liner 1 to enhance the fermentation effect. While stirring, the spiral blade 26 is rotated and is restricted by the limiting rod 28 on the inner side of the lower sleeve 27, causing the sleeve rod 25 to lift the connecting rod 29 upwards. During the upward rotation of the connecting rod 29, the upper end of the connecting rod 29 compresses the spring 31 inside the upper sleeve 30, and the rotating shaft above the connecting rod 29 rotates below the spring 31, ensuring the normal operation of the mechanism. At the same time, the connection between the side stirring rod 10 and the connecting rod 29 is raised, and the stirring rod 10 on the outer side of the sleeve 11 is pressed downwards. After the limiting rod 28 reaches the lowest point of the spiral blade 26, the limiting rod 26... Positioning rod 28 disengages from the gap of spiral blade 26, and spiral blade 26 loses its restrictive function. Spring 31 in upper sleeve 30 presses down connecting rod 29, causing sleeve rod 25 to return to its initial position. Positioning rod 28 returns to the lower part of the upper end of spiral blade 26. This reciprocating motion allows stirring rod 10 to shake downwards during rotation within sleeve 11, increasing the stirring effect and shaking off the residue adhering to the surface of stirring rod 10, reducing residue adhesion to the surface of stirring rod 10, reducing the cleaning burden on stirring rod 10 during subsequent cleaning, and reducing the cleaning time of stirring rod 10. During stirring, insertion rod 24 is inserted into sleeve rod 25 through cross plate, driving sleeve rod 25 and connecting rod 29 to rotate, while sleeve rod 25 can slide up and down above insertion rod 24.

[0048] After fermentation, the fermentation liquid after saccharification and fermentation enters the filter cylinder 33 through the discharge pipe 6. After being filtered by the filter plate 34, the filtrate flows downward through the discharge pipe 38. During the filtration process, the drive motor b36 drives the stirring blade 37 to rotate on the filter plate 34, stirring the liquid to increase the filtration effect. The filtered residue remains above the filter plate 34. After filtration, the cylinder cover 35 is opened to clean the residue inside the filter plate 34 and the stirring rod 10. Because the discharge pipe 38 uses a larger diameter pipe and the filtration function is set in the filter cylinder 33, which is shorter and wider than the saccharification pot, it prevents the residue from clogging the saccharification pot, improves the efficiency of discharging the fermentation liquid, and facilitates the subsequent cleaning of the residue.

[0049] During this process, the water bath layer 2, the filter cylinder 33, and the connected pipes are all equipped with insulation layers (not shown in the figure).

[0050] This concludes the description of the working materials for this device.
