Description

Technical Field

[0001] The invention relates to the field of microbial fermentation, and more specifically to a microbial fermentation reactor for fruit juice production. Background Art

[0002] Juice is a liquid extracted from fruit, usually rich in vitamins, minerals and antioxidants. Depending on the fruit, the taste, color and nutritional content of the juice will vary. Juice can be drunk directly or used to make beverages, desserts and other foods. In order to enhance the flavor and improve the nutritional value, juice usually needs to be fermented during the production process. The metabolism of microorganisms in the fermentation reaction vessel is used to convert the raw materials into juice or improve its flavor and shelf life. This technology can not only improve the nutritional value of the juice, but also give it a unique flavor.

[0003] During the production and fermentation process of juice, sealed fermentation is usually adopted. During the sealed fermentation process, the gas is relatively immobile. However, under the condition of non-flowing gas, not only will the fermentation reaction be uneven, but it will also affect the growth and metabolism of yeast, so that some volatile substances cannot evaporate, resulting in the flavor of the product being suppressed or poor. At the same time, gas accumulation will lead to the formation of other by-products, thereby reducing the efficiency of fermentation and causing the flavor and quality of the final product to be inconsistent, affecting the final taste.

[0034] The ventilation assembly includes a circular plate 7 which is sealingly and slidably mounted on the inner wall of the cylinder 6, the circular plate 7 is fixedly mounted on the rotating rod 3, an air intake hole 13 is provided on the top of the cylinder 6, an air intake hole 2 14 is provided on one side wall of the cylinder 6, a guide hole 17 is provided in the rotating rod 3, an exhaust hole 15 is provided on one side of the top of the circular plate 7, an exhaust hole 2 16 is provided on one side of the bottom of the circular plate 7, the other ends of the exhaust hole 15 and the exhaust hole 2 16 are connected to the inner cavity of the guide hole 17, an air storage cavity 18 is provided in each group of stirring rods 4, and air outlet holes 19 are evenly provided on the outer wall of each group of stirring rods 4, each group of air outlet holes 19 is connected to the inner cavity of the adjacent air storage cavity 18, and each group of air storage cavity 18 is connected to the inner cavity of the guide hole 17.

[0035] First, the components in the reactor 1 and on the sealing cover 2 are completely cleaned and disinfected to prevent any unnecessary microbial contamination. Before the pretreated juice is poured into the reaction barrel 1, additional nutrients are added to the juice, and appropriate microbial strains are selected for inoculation according to the fermentation requirements. Then the treated and inoculated juice is poured into the reaction barrel 1, and then the sealing cover 2 is threadedly installed on the top of the reaction barrel 1. At this time, a sealed fermentation environment is formed in the reaction barrel 1 to prevent the outside air from entering and avoid the entry of miscellaneous bacteria in the air. During the fermentation process, no cleaning and disinfection are performed. The motor 5 is turned on, and the output shaft of the motor 5 will drive the rotating rod 3 to rotate. When the rotating rod 3 rotates, it will drive each group of stirring rods 4 to rotate synchronously to stir the juice in the reaction barrel 1. Stirring can promote the uniform distribution of juice and nutrients, so that the microorganisms can fully contact the nutrients in the culture medium, improve the fermentation efficiency, and at the same time, the stirring juice flow will drive the gas above it. The cylinder 6 is pushed by the support rod 10 to move closely against the bottom inclined surface of the guide tube 11. At this time, the cylinder 6 can reciprocate up and down during the rotation of the rotating rod 3, and the cylinder 6 can slide on the outer wall of the circular plate 7 while the cylinder 6 moves along the bottom inclined surface of the guide tube 11.

[0036] The inner cavities of the suction hole 13, the suction hole 2 14, the exhaust hole 15 and the exhaust hole 2 16 are all equipped with a one-way valve. The inner cavity of the cylinder 6 can only be inhaled through the suction hole 13 and the suction hole 2 14, and exhausted through the exhaust hole 15 and the exhaust hole 2 16, which plays a role of one-way air inlet and outlet. When the cylinder 6 moves downward, the circular plate 7 will squeeze the gas in the inner cavity of the cylinder 6 above it through the exhaust hole 15 and discharge it into the inner cavity of the guide hole 17. At the same time, the circular plate 7 will The gas hole 14 sucks the gas in the inner cavity of the reaction cylinder 1 into the cylinder 6 and is placed below the circular plate 7. When the cylinder 6 moves upward, the circular plate 7 squeezes the gas in the inner cavity of the cylinder 6 below it through the exhaust hole 16 and discharges it into the inner cavity of the guide hole 17. At the same time, the circular plate 7 sucks the gas in the inner cavity of the reaction cylinder 1 into the cylinder 6 through the suction hole 13 and places it above the circular plate 7. The gas in the inner cavity of the guide hole 17 is discharged into the inner cavity of each group of gas storage chambers 18, and then through each group of gas outlet holes. 19 is discharged into the juice, and a one-way valve is installed in the air outlet 19 to prevent the juice from flowing back through the air outlet 19. At this time, during the up and down movement of the cylinder 6, the cylinder 6 can continuously suck the gas in the inner cavity of the reaction cylinder 1 and discharge it into the juice, which can improve the fluidity of the gas in the reaction cylinder 1, effectively improve the fermentation efficiency, thereby improving the uniformity of the fermentation reaction, and avoid the situation in the past where the gas does not flow and the volatile substances cannot be completely volatilized, resulting in the flavor of the product being suppressed or poor, thereby effectively improving the flavor and quality of the final product and improving the taste of the juice; for sampling, a sampling valve can be installed on the reaction cylinder 1, and the sampling valve usually has a sterilization function, allowing samples to be taken without opening the container. When sampling, ensure that the area around the sampling valve has been disinfected. Since it is a sealed fermentation, the reaction cylinder 1 is in a sealed state and no air will enter. Then open the sampling valve, collect the required sample, and quickly close the valve.

[0037] like Figures 4 to 6 As shown, grooves 20 are evenly opened on the bottom wall of the inner cavity of the fixed cylinder 8, iron balls 21 are placed on the bottom wall of the inner cavity of each group of grooves 20, and a fixing frame 22 is provided on the outer wall of each group of iron balls 21, and each group of fixing frames 22 is fixedly installed on the bottom wall of the inner cavity of the fixed cylinder 8.

[0038] An elastic block 23 is fixedly installed on the top of each group of fixed frames 22, and a bayonet 24 compatible with the iron ball 21 is opened on each group of elastic blocks 23. A magnet block 25 is arranged directly above each group of elastic blocks 23, and each group of magnet blocks 25 is fixedly installed on the bottom of the cylinder 6.

[0039] When the cylinder 6 moves up and down, as the cylinder 6 slides downward in the fixed cylinder 8, it will drive the magnet block 25 to move synchronously. The downward movement of the cylinder 6 will squeeze the telescopic spring 9. When the cylinder 6 moves downward to the maximum extent, the magnet block 25 will contact the top of the elastic block 23 in the vertical direction. At this time, the magnet block 25 and the iron ball 21 enter the magnetic attraction range. The iron ball 21 will be adsorbed by the magnet block 25 and separated from the bottom wall of the inner cavity of the groove 20, and moved into the bayonet 24 and magnetically attracted together with the magnet block 25. When the telescopic spring 9 pushes the cylinder 6 to move upward, the bayonet 24 will be pulled upward and stretch the elastic block 23 under the adsorption force of the magnet block 25. When the elastic block 23 is stretched to the maximum extent, the cylinder 6 drives Continuing to move upward, the magnet block 25 will separate from the iron ball 21. At this time, the iron ball 21 can move downward and hit the inner cavity of the groove 20 under the cooperation of the gravity of the iron ball 21 and the elastic force of the elastic block 23. At this time, the iron ball 21 can reciprocately hit the bottom wall of the inner cavity of the groove 20 during the reciprocating movement of the cylinder 6, which can hit and vibrate the fixed cylinder 8. The shock wave will be transmitted to the stirring rod 4 through the rotating rod 3 to vibrate the juice. The vibration can promote the rise and release of carbon dioxide bubbles generated during the fermentation process, and can also help to mix the ingredients in the juice more evenly, which helps to ensure the uniform distribution of yeast and sugar, thereby promoting a more consistent fermentation effect.

[0040] like Figures 1 to 4 As shown, a spiral tube 26 is fixedly installed on the outer wall of the reaction cylinder 1, a circular groove 27 is opened at the bottom of the sealing cover 2, a circular frame 28 is rotatably installed in the inner cavity of the circular groove 27, a fixed tube 29 is fixedly installed on one side of the inner cavity bottom wall of the fixed cylinder 8, the other end of the fixed tube 29 is fixedly installed with the circular frame 28, and the two ends of the fixed tube 29 are respectively connected with the inner cavity of the circular frame 28 and the inner cavity of the fixed cylinder 8.

[0041] A mounting tube 31 is fixedly mounted on one side of the top of the spiral tube 26, and a connecting tube 30 is detachably mounted on the top of the mounting tube 31. The other end of the connecting tube 30 passes through the sealing cover 2 and is connected to the inner cavity of the annular groove 27, and the bottom end of the spiral tube 26 is connected to the outside.

[0042] In the initial state, after the threaded rotating sealing cover 2 is installed on the top of the reaction cylinder 1, it is detachably installed with the connecting tube 30 through the installation tube 31, and the top of the rotatable installation tube 31 is installed with the connecting tube 30. When the sealing cover 2 needs to be removed, the connecting tube 30 is first disassembled and separated from the installation tube 31, and then the sealing cover 2 is rotated to be removed from the top of the reaction cylinder 1, so that the sealing cover 2 and the parts thereon can be completely removed, which plays a role in facilitating disassembly, and is convenient for cleaning, repairing and replacing the parts on the sealing cover 2. In the initial state, the reaction cylinder 1 is placed in an environment with a temperature range of 20°C to 30°C, which can usually provide a good fermentation environment for the fermentation of most microorganisms. During the rotation of the fixed cylinder 8 driven by the rotating rod 3, the annular frame 28 is driven to rotate in the inner cavity of the annular groove 27 through the fixed tube 29. At the same time, the cylinder 6 moves up and down in the inner cavity of the fixed cylinder 8 during the up and down movement on the rotating rod 3. When the cylinder 6 moves downward, the cylinder 6 squeezes the gas in the inner cavity of the fixed cylinder 8 and discharges it into the annular frame 2 through the fixed tube 29. 8, these gases will enter the annular groove 27 and be discharged into the mounting tube 31 through the connecting tube 30, and then be discharged into the spiral tube 26 through the mounting tube 31 and be discharged after spirally flowing downward in the inner cavity of the spiral tube 26. When the cylinder 6 moves upward in the inner cavity of the fixed cylinder 8, the cylinder 6 will extract the external gas through the fixed tube 29, the annular groove 27, the connecting tube 30, the mounting tube 31 and the spiral tube 26, so that the external gas can be sucked into the spiral tube 26 and flow upward in the spiral. At this time, during the up and down movement of the cylinder 6 It is possible to reciprocately draw external gas into the spiral tube 26 and then discharge it, realize the exchange of gas between the spiral tube 26 and the external gas, make the reaction tube 1 adapt to the environment at room temperature, and keep the reaction tube 1 in a constant temperature state under the room temperature environment, play a role of constant temperature fermentation, and realize self-control of the temperature of the reaction tube 1, which can effectively improve the growth and metabolism of microorganisms, avoid the heat generation during the fermentation process that causes the temperature of the reaction tube 1 to be too high, thereby affecting the activity of the microorganisms and the fermentation effect, and thus can effectively improve the fermentation effect.

[0043] like Figures 1 to 6 As shown, a discharge pipe 33 is fixedly installed on one side of the top of the reaction cylinder 1, and a one-way valve is fixedly installed in the inner cavity of the discharge pipe 33.

[0044] The telescopic spring 9 is in a compressed state in its initial state, and the bottom of the guide tube 11 is arranged in an oblique shape.

[0045] A connecting plate 32 is fixedly mounted on one side of the cylinder 6 and the fixed cylinder 8 .

[0046] The distance between the magnet block 25 and the elastic block 23 in the vertical direction is the same as the height of the guide tube 11 .

[0047] During the sealed fermentation process, air and oxygen can be prevented from entering, and the sealed fermentation does not require the addition of oxygen to the reaction cylinder 1, and the gas in the reaction cylinder 1 does not need to be exchanged with the outside gas. Carbon dioxide will be generated during the fermentation process, and the pressure inside the reaction cylinder 1 will usually increase as the fermentation proceeds. After the pressure inside the reaction cylinder 1 increases, the gas inside will be automatically discharged through the discharge pipe 33 to maintain the stability of the fermentation process. By setting the one-way valve in the discharge pipe 33, the outside gas will not enter the reaction cylinder 1 through the discharge pipe 33, and the rotating rod 3 drives the cylinder 6 and the fixed cylinder 3 to rotate. 8 rotates, the cylinder 6 and the fixed cylinder 8 will respectively drive the connecting plates 32 thereon to rotate synchronously. The setting of the connecting plates 32 can achieve stirring of the gas in the reaction cylinder 1 during the circular rotation, further improving the fluidity of the gas in the reaction cylinder 1. The distance between the magnet block 25 and the elastic block 23 in the vertical direction is the same as the height of the guide tube 11. When the ball 12 moves from the highest point to the lowest point on the bottom slope of the guide tube 11, the cylinder 6 will drive the magnet block 25 to move downward to the top of the elastic block 23, so that the magnet block 25 can magnetically attract the iron ball 21.

[0048] Working principle: first, pour the processed and inoculated juice into the reaction cylinder 1, then install the sealing cover 2 on the top of the reaction cylinder 1 by threading, install the top of the installation tube 31 and the connecting tube 30 together, turn on the motor 5, and the output shaft of the motor 5 drives the stirring rod 4 to rotate through the rotating rod 3 to stir the juice in the reaction cylinder 1. The rotation of the rotating rod 3 will drive the cylinder 6 and the fixed cylinder 8 to rotate. The rotation of the cylinder 6 and the fixed cylinder 8 will drive the connecting plate 32 to rotate to stir the gas in the reaction cylinder 1. The cylinder 6 rotates through the support rod 10 and the ball 12 and moves up and down on the bottom slope of the guide tube 11 with the cooperation of the telescopic spring 9. Movement, through the cooperation of the circular plate 7, the inner cavity of the cylinder 6 can continuously suck the gas in the inner cavity of the reaction cylinder 1 and discharge it into the juice, so as to improve the fluidity of the gas in the reaction cylinder 1, and the cylinder 6 will move synchronously in the inner cavity of the fixed cylinder 8 while moving up and down. Through the cooperation of the iron ball 21 and the magnet block 25, the iron ball 21 can reciprocately hit the bottom wall of the inner cavity of the fixed cylinder 8, and the juice can be vibrated by the stirring rod 4. At the same time, the cylinder 6 will reciprocally suck the external gas into the spiral tube 26 and discharge it to the outside again while moving up and down in the inner cavity of the fixed cylinder 8, so that the gas in the spiral tube 26 can be reciprocally replaced, so that the reaction cylinder 1 maintains a constant temperature.

[0049] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
