Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular to a microbial engineering fermentation device. Background Technology

[0002] Fermented rice has a long history. Practice has shown that rice products made from fermented rice have significantly improved taste and flavor. Rice contains 90% starch, about 8% protein, and small amounts of fat and ash. Under certain moisture, temperature, and pH conditions, microorganisms such as lactic acid bacteria and yeast added to the rice will use these substances to grow, which is fermentation.

[0003] Traditional fermentation typically relies on natural processes with little or no intervention, making it susceptible to external environmental factors such as temperature, humidity, and pH. This leads to unstable fermentation conditions and uncertain results. Specifically, fermentation time is unpredictable, potentially taking several days or even a week or two, resulting in low production efficiency. Fermentation outcomes are uncontrolled, potentially leading to incomplete fermentation or excessive levels of contaminating bacteria. While some fermenters incorporate manual controls, these methods have drawbacks. For example, the use of paddles to slowly stir the rice to ensure even fermentation often results in high rice breakage rates. Significant rice loss occurs during washing, leading to a high loss rate. Furthermore, the process of washing, soaking, and fermenting rice requires multiple tanks connected in parallel, making it impossible to achieve integrated, balanced management of these processes. Summary of the Invention

[0004] The purpose of this invention is to provide a microbial engineering fermentation device that solves the problem that existing fermenters cannot achieve balanced management of cleaning, soaking, and fermentation in one integrated manner.

[0005] To achieve the above objectives, the present invention provides a microbial engineering fermentation device, including a heater, a water supply heating component, an integrated tank component, and a fermentation broth circulation component; The integrated tank assembly includes a tank body, a tank head, a rice inlet pipe, a return air pipe, a conical cylinder, a water inlet pipe, a high-pressure component, and an overflow component. The tank head is located at the top of the tank body. The rice inlet pipe is fixedly connected to the tank head and located at the upper end of the tank head. The return air pipe is fixedly connected to the tank head and located at the upper end of the tank head. The conical cylinder is fixedly connected to the tank body and located at the lower end of the tank body. The water inlet pipe is fixedly connected to the tank body and located on the outer wall of the tank body. The high-pressure component is connected to the conical cylinder. The overflow component is connected to the tank body. The heater is located on the outer wall of the tank body. The water supply and heating component is connected to the water inlet pipe. The fermentation liquid circulation component is connected to the tank body.

[0006] The integrated tank assembly further includes lifting rings and a circular manhole. There are multiple lifting rings, the lower ends of which are fixedly connected to the tank body and are evenly distributed along the edge of the tank body. The circular manhole is fixedly connected to the tank head and is located at the upper end of the tank head.

[0007] The high-pressure component includes an air inlet box, a liquid level connecting pipe, a drain pipe, an air inlet pipe, and a conical filter screen. The air inlet box is fixedly connected to the conical cylinder and is located on the side wall of the conical cylinder. The liquid level connecting pipe is located at the upper end of the left side of the air inlet box, the drain pipe is located at the lower end of the left side of the air inlet box, and the air inlet pipe is located at the rear of the air inlet box. The air inlet pipe is fixedly connected to high-pressure gas. The conical filter screen is located inside the air inlet box.

[0008] The overflow component includes an overflow tank, an overflow filter, and an overflow pipe. The overflow tank is fixedly connected to the tank body and located on the outer wall of the tank body; the overflow filter is fixedly connected to the tank body and located inside the overflow tank; and the overflow pipe is fixedly connected to the overflow tank and located at the bottom of the overflow tank.

[0009] The integrated tank assembly also includes a level gauge, the upper end of which is fixedly connected to the tank body, and the lower end of which is fixedly connected to the level connection pipe.

[0010] The water supply heating assembly includes a sealing plate, a heating pipe, a flange, a cylinder, an outlet pipe, and an inlet pipe. The heating pipe is fixedly connected to the sealing plate; the flange is fixedly connected to the sealing plate and is located at the upper end of the sealing plate; the cylinder is fixedly connected to the flange and is located at the upper end of the flange; the outlet pipe is connected to both the cylinder and the inlet pipe and is located at the upper end of the cylinder; the inlet pipe is connected to the cylinder and is located at the upper end of the cylinder.

[0011] The heater includes a cylindrical heating belt and a conical heating belt. The cylindrical heating belt is fixedly connected to the cylinder and located on the outer wall of the cylinder. The conical heating belt is fixedly connected to the conical cylinder and located on the outer wall of the conical cylinder.

[0012] This invention discloses a microbial engineering fermentation device. The tank opening is sealed by a tank head. A rice inlet pipe and a return air pipe are fixedly connected to a rice conveyor to introduce rice into the tank. A water inlet pipe is connected to a water supply and heating component to supply hot water into the tank. A high-pressure component introduces high-pressure gas into the rice-water mixture inside the tank from the bottom, causing the rice at different locations within the tank to tumble thoroughly. Using high-pressure gas to agitate the rice replaces the mechanical stirring of the agitator blades, ensuring thorough tumbling and washing away dust, bran, and other impurities adhering to the rice surface, which are then discharged through the overflow component. Additionally, it agitates the rice deposited at the bottom of the conical cylinder, ensuring uniform washing. This washing method reduces rice breakage and prevents insufficient washing of rice deposited at the bottom due to compaction. The temperature inside the fermentation tank is regulated by a temperature equalization management device controlled by the heater. Multiple sensors on the outer wall of the tank detect parameters such as temperature, pH, and oxygen content, transmitting these parameters to the equalization management device. This device stores predetermined values ​​for microbial engineering treatment and optimal condition curves for the selected strains. A fermentation process condition control device automatically controls the fermentation process based on preset conditions at different time points. The main control module of this device is a PLC, powered by a power supply module. The main control module receives temperature data from the input module, monitors the temperature parameters inside the fermentation tank in real time, and controls the heater to maintain the temperature within the preset condition curve range. A pH sensor, electrically connected to the main control module via an input module, monitors the pH of the fermentation broth in real time and automatically adjusts the pH to the preset condition curve range by adding acid or alkali solutions. An oxygen sensor, also electrically connected to the main control module via an input module, absorbs the dissolved oxygen content in the fermentation broth by immersing its probe in the tank, converting it into an electrical signal and transmitting it to the main control module. The high-pressure gas injection rate and flow rate are controlled to maintain oxygen levels within the preset stage condition curve range. Simultaneously, the flow rate of the fermentation broth within the fermentation broth circulation component is controlled to achieve uniform mixing, promoting mass transfer and dissolved oxygen distribution. Providing a suitable temperature, oxygen, and pH environment for the fermentation process helps improve fermentation quality and efficiency. Suitable temperature, pH, and oxygen levels accelerate microbial metabolism, promote fermentation reactions, and shorten fermentation time. Furthermore, the fermentation broth circulation component maintains balanced fermentation conditions in different areas within the tank, resulting in uniform fermentation. This helps maintain the stability and consistency of the fermentation process, ensuring that fermentation conditions develop according to the preset stage condition curve to achieve optimal results. Fermentation parameters can be precisely set and adjusted to guarantee product quality stability and consistency. It shortens the fermentation cycle, improves fermentation efficiency, and achieves integrated balanced management of cleaning, soaking, and fermentation. Attached Figure Description

This invention provides a microbial engineering fermentation device: comprising a heater, a water supply and heating assembly, an integrated tank assembly, and a fermentation broth circulation assembly. The integrated tank assembly includes a tank body 101, a tank end cap 102, a rice inlet pipe 103, a return air pipe 104, a conical cylinder 105, a water inlet pipe 106, a high-pressure component, an overflow component, a lifting ring buckle 107, a circular manhole 108, and a level gauge 117. The high-pressure component includes an air inlet box 109, a level connection pipe 110, a drain pipe 111, an air inlet pipe 112, and a conical filter screen 113. The overflow component includes an overflow tank 114, an overflow filter 115, and an overflow pipe 116. The water supply heating assembly includes a sealing plate 118, a heating pipe 119, a flange 120, a cylinder 121, an outlet pipe 122, and an inlet pipe 123. The heater includes a cylindrical heating belt 124 and a conical heating belt 125. The fermentation liquid circulation assembly includes a filter 126, a first inlet pipe 127, a first valve 128, a second inlet pipe 129, a circulation pump 130, a second valve 131, and a discharge pipe 132.

[0026] In this specific embodiment, the tank head 102 is located at the top of the tank 101, the rice inlet pipe 103 is fixedly connected to the tank head 102 and located at the upper end of the tank head 102, the return air pipe 104 is fixedly connected to the tank head 102 and located at the upper end of the tank head 102, the conical cylinder 105 is fixedly connected to the tank 101 and located at the lower end of the tank 101, the water inlet pipe 106 is fixedly connected to the tank 101 and located on the outer wall of the tank 101, the high-pressure component is connected to the conical cylinder 105, the overflow component is connected to the tank 101, the heater is located on the outer wall of the tank 101, the water supply heating component is connected to the water inlet pipe 106, and the fermentation liquid circulation component is connected to the tank 101. The number of lifting ring buckles 107 is multiple, and the lower ends of the multiple lifting ring buckles 107 are fixedly connected to the tank body 101, and are evenly distributed along the edge of the tank body 101; the circular manhole 108 is fixedly connected to the tank head 102 and is located at the upper end of the tank head 102.

[0027] The upper end of the tank head 102 is fixedly connected to the rice inlet pipe 103 and the return air pipe 104, and the upper end of the tank head 102 is fixedly connected to the circular manhole 108 for easy maintenance and operation. Evenly distributed lifting ring clips 107 are fixedly connected along the edge of the tank 101, and the lower end of the lifting ring clips 107 is fixedly connected to the tank 101, securing the tank 101 and the tank head 102. The outer wall of the tank 101 is provided with a water inlet pipe 106, which communicates with the water outlet pipe 122 of the water supply and heating component. The rice inlet pipe 103 and the return air pipe 104 are fixedly connected to and communicate with the rice conveyor, guiding rice into the tank 101. An overflow component is provided on the upper side wall of the tank 101. The lower end of the tank 101 is fixedly connected to a conical cylinder 105, which is connected to the high-pressure component.

[0028] The air inlet box 109 is fixedly connected to the conical cylinder 105 and is located on the side wall of the conical cylinder 105; the upper left side of the air inlet box 109 is provided with the liquid level connecting pipe 110, the lower left side of the air inlet box 109 is provided with the drain pipe 111, the rear of the air inlet box 109 is provided with the air inlet pipe 112, and the air inlet pipe 112 is fixedly connected to high-pressure gas; the conical filter screen 113 is located inside the air inlet box 109.

[0029] The conical filter 113 has a mesh size smaller than the diameter of rice grains, ensuring that rice can only be discharged from the drain pipe 111 of the rice-water mixture. The conical filter 113 isolates the water used for washing and soaking the rice from the air inlet pipe 112 and the liquid level connection pipe 110, preventing rice from entering and clogging the pipes. By introducing high-pressure gas into the rice-water mixture from the bottom, the rice at different positions in the tank is fully tumbled. The high-pressure gas agitates the rice instead of mechanically stirring with a paddle, ensuring thorough tumbling and washing away dust, bran, and other impurities adhering to the rice surface, which are then discharged through the overflow filter 115. Additionally, it agitates the rice deposited at the bottom of the conical cylinder 105, ensuring uniform washing. This washing method reduces rice breakage and prevents insufficient washing of rice deposited at the bottom due to compression.

[0030] Secondly, the overflow tank 114 is fixedly connected to the tank body 101 and is located on the outer wall of the tank body 101; the overflow filter screen 115 is fixedly connected to the tank body 101 and is located inside the overflow tank 114; the overflow pipe 116 is fixedly connected to the overflow tank 114 and is located at the bottom of the overflow tank 114.

[0031] The overflow tank 114 is equipped with an overflow filter 115 for filtering the soaking solution. The overflow filter 115 is fixedly welded to the outer wall of the tank body 101, and the mesh size of the overflow filter 115 is less than or equal to the diameter of rice grains. During the washing process, when fresh water is introduced again through the water inlet pipe 106 above the tank body 101, if the liquid level rises above the upper edge of the overflow filter 115, it will be discharged through the overflow filter 115 and finally out through the overflow pipe 116. The mesh size of the overflow filter 115 is smaller than the diameter of the rice grains, and its function is to prevent the rice from being tumbled and discharged from the overflow pipe when high-pressure gas is introduced, thus preventing rice loss.

[0032] Meanwhile, the upper end of the level gauge 117 is fixedly connected to the tank 101, and the lower end of the level gauge 117 is fixedly connected to the level connection pipe 110. When the level gauge 117 detects that the water injected into the tank 101 has reached a set value, it stops adding water.

[0033] In addition, the heating tube 119 is fixedly connected to the sealing plate 118; the flange 120 is fixedly connected to the sealing plate 118 and is located at the upper end of the sealing plate 118; the cylinder 121 is fixedly connected to the flange 120 and is located at the upper end of the flange 120; the water outlet pipe 122 is connected to the cylinder 121 and the water inlet pipe 106 respectively, and is located at the upper end of the cylinder 121; the inlet pipe 123 is connected to the cylinder 121 and is located at the upper end of the cylinder 121.

[0034] The sealing plate 118 has multiple evenly spaced circular holes on its upper surface, and the heating tube 119 is fixedly connected to each of these holes. The flange 120 is fixedly connected to the upper end of the sealing plate 118, and the cylinder 121 is fixedly connected to the upper end of the flange 120. The cylinder 121 covers the heating tube 119, and its upper end is connected to the inlet pipe 123 and the outlet pipe 122. The outlet pipe 122 is connected to the inlet pipe 106 of the tank 101. Water is introduced into the cylinder 121 through the inlet pipe 123, heated by the heating tube 119, and then introduced into the inlet pipe 106 from the outlet pipe 122 for use.

[0035] Meanwhile, the cylindrical heating belt 124 is fixedly connected to the cylinder 121 and located on the outer wall of the cylinder 121; the conical heating belt 125 is fixedly connected to the conical cylinder 105 and located on the outer wall of the conical cylinder 105.

[0036] The cylindrical heating belt 124 and the conical heating belt 125 are fixedly connected to the outer walls of the tank body 101 and the conical cylinder 105, respectively, and are laid along the circumferential surface of the outer walls of the tank body 101 and the conical cylinder 105. This ensures uniform heating temperature of the integrated tank assembly, provides a suitable temperature environment for the fermentation process, and helps improve fermentation efficiency. A suitable temperature can accelerate the metabolic rate of microorganisms, promote the fermentation reaction, and shorten the fermentation time.

[0037] Finally, the fermentation broth circulation assembly includes a filter screen 126, a first inlet pipe 127, a first valve 128, a second inlet pipe 129, a circulation pump 130, a second valve 131, and a discharge pipe 132. The first inlet pipe 127 is connected to the tank body 101 and is located on the outer wall of the tank body 101. The filter screen 126 is disposed at the inlet of the first inlet pipe 127. The first valve 128 is located between the first inlet pipe 127 and the second inlet pipe 129, and the second inlet pipe 129 is located below the filter screen 126. The circulation pump 130 is connected to the first inlet pipe 127 and is located below the second inlet pipe 129. The second valve 130 is connected to the first inlet pipe 127 and is located below the circulation pump 130. The discharge pipe 132 is located between the circulation pump 130 and the second valve 131.

[0038] Multiple fermentation liquid circulation components are radially and evenly distributed on the outer wall of the tank 101. Each fermentation liquid circulation component includes a filter screen 126, a first water inlet pipe 127, a second water inlet pipe 129, a discharge pipe 132, a circulation pump 130, a first valve 128, and a second valve 131, all of which are interconnected. Its function is to clean and soak rice. During small-batch production, when the surface of the added rice is approximately 20cm below the lower edge of the second water inlet pipe 129, the circulation pump 130 is activated. The second water inlet pipe 129 draws water from inside the tank 101, which is then transported into the conical cylinder 105 via the first valve 128, the circulation pump 130, the discharge pipe 132, and the filter screen. During mass production, when the surface of the added rice is approximately 20 cm below the surface of the first water inlet pipe 127, the circulation pump 130 is activated, the first valve 128 is closed, and the water inside the tank 101 is drawn out by the first water inlet pipe 127. The water is then pumped into the conical cylinder 105 via the circulation pump 130, the discharge pipe 132, and the filter screen 126. This circulates the fermentation liquid inside the tank 101, preventing the formation of hot and cold zones. Increasing the fluidity of the fermentation liquid helps maintain the stability and consistency of the fermentation process, ensuring a relatively constant and suitable fermentation environment.

[0039] Using a microbial engineering fermentation device according to this embodiment, the rice washing, soaking, and fermentation process is as follows: A pneumatic conveyor is turned on to transport rice into the tank 101. The amount of rice added should be such that the surface of the added rice is approximately 40 cm below the lower edge of the first water inlet pipe 127 of the fermentation liquid circulation component. Simultaneously, the water supply heating component is turned on, and water is introduced through the inlet pipe 123 at a temperature of approximately 15°C. The water is then heated to approximately 48°C by the heating pipe 119 and injected into the tank. When the water level exceeds the overflow port, the water supply heating component is turned off. During the washing process, high-pressure gas is intermittently introduced into the bottom of the conical cylinder 105 through the air inlet pipe 112, causing the rice to tumble thoroughly. This washes away dust, bran, and other impurities adhering to the surface of the rice, which are then discharged through the overflow filter 115. Additionally, the rice deposited at the bottom of the conical cylinder 105 is agitated to ensure uniform washing. After washing, the rice and soaking water are left to stand in the tank for microbial treatment, allowing the rice to fully absorb sufficient water. The temperature inside the fermentation tank is controlled by the heater through a balanced management device. Multiple sensors are installed on the outer wall of the tank 101 to detect the internal temperature and transmit the data to the balanced management device. This device stores predetermined values ​​for microbial engineering treatment. When the internal temperature falls below the maximum set value, the balanced management device controls the heater to heat the tank rapidly. When the internal temperature exceeds the maximum set value, the balanced management device stops heating, effectively controlling the internal temperature. This provides a suitable temperature environment for the fermentation process, improving fermentation efficiency. A suitable temperature accelerates microbial metabolism, promotes the fermentation reaction, and shortens fermentation time. Simultaneously, the fermentation broth circulation component circulates water within the tank 101, preventing the formation of hot and cold zones. This helps maintain the stability and consistency of the fermentation process, ensuring a relatively constant and suitable fermentation environment. Fermentation parameters can be precisely set and adjusted, guaranteeing product quality stability and consistency. This shortens the fermentation cycle, improves fermentation efficiency, and achieves integrated balanced management of cleaning, soaking, and fermentation.
