Description

Technical Field

[0001] This utility model relates to the field of biosynthesis and fermentation technology, and in particular to a monitoring device for allulose fermentation. Background Technology

[0002] Allulose is a naturally occurring but scarce monosaccharide, also known as a rare sugar. The allulose fermentation monitoring device is specifically designed for real-time monitoring of key parameters during allulose fermentation. Its core function is to utilize, for example, near-infrared spectroscopy to detect the concentration of allulose in the fermentation broth, the residual amount of substrates (such as glucose and fructose), and the content of byproducts. A gas detection module analyzes the composition of fermentation exhaust gas, indirectly reflecting the metabolic intensity of microorganisms (such as changes in respiratory entropy) through oxygen consumption rate and carbon dioxide generation rate. This allows for precise capture of changes in the fermentation system, providing data support for optimizing the fermentation process, ensuring stable operation, and controlling product quality.

[0003] Existing monitoring devices utilize concealed ventilation slots or heat dissipation fins in their outer casing to create efficient natural convection channels, promoting natural airflow within the device and dissipating heat to the surrounding environment. However, allulose fermentation monitoring devices integrate multi-parameter detection modules (such as HPLC and near-infrared spectrometers), and some modules (such as light sources, pumps, and data processing units) generate significant heat during operation. Natural convection relies solely on passive airflow for heat dissipation, resulting in a low heat transfer rate that cannot quickly remove concentrated heat. This leads to localized components remaining at high temperatures for extended periods, shortening their lifespan. Current technologies improve heat dissipation efficiency by installing small fans or blowers inside the monitoring device to force airflow. However, existing fans are fixed in position and have a single airflow direction, either horizontally forward or vertically upward. This creates a "linear airflow channel" that only covers a few components along the channel, while areas outside the channel become heat dissipation blind spots, causing localized high temperatures within the equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a monitoring device for allulose fermentation, which aims to improve the problem that the existing fan has a fixed position and a single air outlet direction, and the airflow only covers a few parts along the air duct, thus leading to local high temperature in the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a monitoring device for allulose fermentation, comprising a fermenter, a monitoring cabinet disposed on the right side of the outer wall of the fermenter, a cooling mechanism slidably connected to the right side of the inner wall of the monitoring cabinet for heat dissipation, and multiple mixing mechanisms rotatably connected at equal intervals to the top of the inner wall of the fermenter, the multiple mixing mechanisms being used for crushing and stirring respectively; the cooling mechanism includes a movable plate slidably connected to the right side of the inner wall of the monitoring cabinet, and multiple cooling fans fixedly connected at equal intervals to the left side of the outer wall of the movable plate, batteries fixedly connected to the front and rear sides of the outer walls of the cooling fans, and a drive assembly fixedly connected to the outer wall of the monitoring cabinet.

[0006] As a further description of the above technical solution: The drive assembly includes a first motor, which is fixedly connected to the right side of the outer wall of the monitoring cabinet. A connecting rod is fixedly connected to the output end of the first motor. An elongated vertical plate is fixedly connected to the bottom of the inner wall of the monitoring cabinet. A drive wheel is rotatably connected to the upper left side of the outer wall of the elongated vertical plate. A driven wheel is rotatably connected to the lower left side of the outer wall of the elongated vertical plate. A transmission belt is driven to the outer wall of the drive wheel. The driven wheel and the drive wheel are driven to each other via the transmission belt. Multiple elongated short plates are fixedly connected at equal intervals to the left side of the outer wall of the elongated vertical plate. A column is fixedly connected to the middle of an adjacent side of the outer wall of each elongated short plate.

[0007] As a further description of the above technical solution: The mixing mechanism includes a threaded lifting rod rotatably connected to the top of the fermenter. An L-shaped scraper is fixedly connected to the bottom end of the threaded lifting rod. A rotating short column is rotatably connected to the top left side of the fermenter. Multiple crushing blades are fixedly connected at equal intervals to the outer wall of the rotating short column. A power assembly is fixedly connected to the front end of the top of the fermenter.

[0008] As a further description of the above technical solution: The power assembly includes a second motor, which is fixedly connected to the top front end of the fermenter. A worm gear is fixedly connected to the output end of the second motor, and worm wheels are fixedly connected to the top ends of both the rotating short column and the threaded lifting rod.

[0009] As a further description of the above technical solution: The worm gear meshes with the worm wheel, and the bottom end of the threaded lifting rod is rotatably connected to the bottom of the inner wall of the fermenter.

[0010] As a further description of the above technical solution: The inner wall of the movable plate is slidably connected to the outer wall of the column, and the middle part of the inner wall of the movable plate is fixedly connected to the outer wall of the transmission belt.

[0011] As a further description of the above technical solution: A feed pipe is connected to the left side of the outer wall of the fermenter, and a vent pipe is connected to the right side of the outer wall of the fermenter. The end of the vent pipe is connected to the monitoring cabinet.

[0012] As a further description of the above technical solution: A near-infrared monitor is fixedly connected to the left front end of the outer wall of the monitoring cabinet, and a barometric pressure monitor is fixedly connected to the right front end of the outer wall of the monitoring cabinet. Multiple ventilation slots are equidistantly opened on the rear side of the outer wall of the monitoring cabinet.

[0013] This utility model has the following beneficial effects: 1. In this utility model, during monitoring, the fermenter is fed with materials through the feed pipe, and the vent pipe vents the fermenter and guides some of the gas to the monitoring cabinet; the near-infrared monitor monitors the fermentation status, and the air pressure monitor monitors the air pressure in the cabinet. During heat dissipation, the air-cooling mechanism operates: the first motor starts, drives the active rotating wheel to rotate through the connecting rod, and drives the driven rotating wheel to rotate through the transmission belt, so that the moving plate fixed to the transmission belt slides up and down along the column on the right side of the inner wall of the monitoring cabinet. The cooling fan on the moving plate is powered by a battery and cools the monitoring cabinet as it moves. The hot air is discharged through the ventilation slot to avoid local high temperature.

[0014] 2. In this utility model, the second motor of the power component starts and drives the worm to rotate. Because the worm meshes with the worm wheel at the top of the rotating short column and the threaded lifting rod, it drives both to rotate synchronously. The crushing blade of the rotating short column rotates and crushes the material. The threaded lifting rod lifts the material through the thread, and its bottom L-shaped scraper scrapes the material at the bottom of the tank to achieve stirring and turning, ensuring uniform mixing.

[0018] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a monitoring device for allulose fermentation, comprising a fermenter 1, a monitoring cabinet 8 disposed on the right side of the outer wall of the fermenter 1, a cooling mechanism 2 slidably connected to the right side of the inner wall of the monitoring cabinet 8 for heat dissipation, and multiple mixing mechanisms 3 rotatably connected at equal intervals to the top of the inner wall of the fermenter 1 for crushing and stirring respectively; the cooling mechanism 2 includes a movable plate 201 slidably connected to the right side of the inner wall of the monitoring cabinet 8, and multiple cooling fans 202 fixedly connected at equal intervals to the left side of the outer wall of the movable plate 201, the cooling fans 202 being of the silent type. The general components and working principle of 202 are as follows: a DC brushless motor drives the fan blades to rotate under circuit control. The optimized fan blade structure draws in cool air from the intake side of the monitoring cabinet 8, guides it through the housing's airflow structure, and blows it towards the heat-generating components inside the monitoring cabinet 8. Batteries 203 are fixedly connected to the front and rear sides of the outer wall of the cooling fan 202. A drive assembly 204 is fixedly connected to the outer wall of the monitoring cabinet 8. The drive assembly 204 includes a first motor 2041, which is fixedly connected to the right side of the outer wall of the monitoring cabinet 8. A connecting rod 2042 is fixedly connected to the output end of the first motor 2041. The bottom of the inner wall of the monitoring cabinet 8 is fixed... A long vertical plate 2043 is connected to the drive wheel 2044, which is rotatably connected to the upper left side of the outer wall of the long vertical plate 2043. A driven wheel 2046 is rotatably connected to the lower left side of the outer wall of the long vertical plate 2043. A drive belt 2045 is drivenly connected to the outer wall of the drive wheel 2044. The driven wheel 2046 and the drive wheel 2044 are drivenly connected via the drive belt 2045. The drive belt 2045 is used to transmit power. The driven wheel 2046 and the drive wheel 2044 are drivenly connected via the drive belt 2045, forming a complete transmission structure. Multiple long short plates 2047 are fixedly connected at equal intervals on the left side of the outer wall of the long vertical plate 2043. A column 2048 is fixedly connected to the middle of the adjacent side of the outer wall of the long short plate 2047. The inner wall of the movable plate 201 is slidably connected to the outer wall of the column 2048. The middle of the inner wall of the movable plate 201 is fixedly connected to the outer wall of the transmission belt 2045. The inner wall of the movable plate 201 is slidably connected to the outer wall of the column 2048 to ensure that the movable plate 201 moves smoothly along a fixed trajectory. The middle of the inner wall of the movable plate 201 is fixedly connected to the outer wall of the transmission belt 2045 so that the movable plate 201 can move synchronously when the transmission belt 2045 moves. Specifically, during monitoring, fermentation material is added to fermentation tank 1 through feed pipe 6, and gas is introduced into fermentation tank 1 through vent pipe 7. Simultaneously, some gas is introduced into monitoring cabinet 8. Near-infrared monitor 4 monitors the fermentation process in fermentation tank 1, and gas pressure monitor 5 monitors the gas pressure inside cabinet 8. During heat dissipation, air-cooling mechanism 2 operates, and the first motor 2041 starts. Its output drives connecting rod 2042 to rotate, causing drive wheel 2044 to rotate. Drive wheel 2044 drives driven wheel 2046 to rotate via transmission belt 2045. Due to the moving plate... 201 is fixedly connected to the transmission belt 2045 and slides along the column 2048. The column 2048 is fixed on the elongated short plate 2047, which is installed on the elongated upright plate 2043. When the transmission belt 2045 moves, it drives the moving plate 201 to slide up and down on the right side of the inner wall of the monitoring cabinet 8. Multiple cooling fans 202 on the moving plate 201 are powered by the battery 203 and start. During the movement of the moving plate 201, they provide more comprehensive heat dissipation for the inside of the monitoring cabinet 8. Hot air is discharged through the ventilation slot 9, which avoids the problem of local high temperature in the equipment.

[0019] Reference Figure 1 , Figure 3 and Figure 5 The mixing mechanism 3 includes a threaded lifting rod 301, which is rotatably connected to the top of the fermentation tank 1. An L-shaped scraper 302 is fixedly connected to the bottom end of the threaded lifting rod 301. A rotating short column 303 is rotatably connected to the top left side of the fermentation tank 1. Multiple crushing blades 304 are fixedly connected at equal intervals to the outer wall of the rotating short column 303. A power assembly 305 is fixedly connected to the front end of the top of the fermentation tank 1. The power assembly 305 includes a second motor 3051, which is fixedly connected to the front end of the top of the fermentation tank 1. A worm gear 3052 is fixedly connected to the output end of the second motor 3051. The rotating short column 303 and the threaded lifting rod 301... The top of each is fixedly connected to a worm gear 3053, and the worm 3052 is meshed with the worm gear 3053. The bottom end of the threaded lifting rod 301 is rotatably connected to the bottom of the inner wall of the fermentation tank 1. The first motor 2041 and the second motor 3051 are both of model Y100l2-4. The basic components are: base, iron core, winding, end cover, bearing, centrifugal switch or starting relay and PTC starter. The working principle is: after the power is turned on, the main winding, working winding and starting winding are connected to the starting device and energized at the same time to form a rotating magnetic field. The rotating magnetic field cuts the rotor winding and generates an induced current. The rotor rotates with the magnetic field under the action of electromagnetic force. Specifically, after the second motor 3051 in the power assembly 305 starts, its output end drives the worm gear 3052 to rotate. Since the worm gear 3052 is meshed with the rotating short column 303 and the worm wheel 3053 at the top of the threaded lifting rod 301, the worm gear 3052 will synchronously drive the two worm wheels 3053 to rotate, thereby driving the rotating short column 303 and the threaded lifting rod 301 to rotate. When the rotating short column 303 rotates, the multiple crushing blades 304 on its outer wall rotate with it to crush the material in the fermentation tank 1. During the rotation of the threaded lifting rod 301, it generates an upward lifting force on the material through its own thread structure. At the same time, the L-shaped scraper 302 at its bottom rotates with it to scrape the material at the bottom of the inner wall of the fermentation tank 1, realizing the stirring and turning of the material and ensuring that the material is mixed evenly.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A feed pipe 6 is connected to the left side of the outer wall of fermenter 1, and a vent pipe 7 is connected to the right side of the outer wall of fermenter 1. The end of the vent pipe 7 is connected to the monitoring cabinet 8. A near-infrared monitor 4 is fixedly connected to the left side of the front end of the outer wall of the monitoring cabinet 8. The model of the near-infrared monitor 4 is NIR2000 miniature near-infrared spectrometer. The components and working principle of the near-infrared monitor 4 are as follows: When the near-infrared monitor 4 is working, the near-infrared light emitted by the light source module is irradiated into the fermentation liquid in fermenter 1 by the sampling module such as the fiber optic probe. Molecules in the fermentation liquid, such as allulose and glucose, will absorb near-infrared light of specific wavelengths. The absorption intensity is related to the molecular concentration. The light signal after the sample is processed is collected by the sampling module and transmitted to the spectrometer to be decomposed into monochromatic light of different wavelengths. Then, the detection module converts the light intensity of each wavelength into an electrical signal, and the data processing module processes the electrical signal. The signal is processed to generate a near-infrared spectrum of the sample. The spectral information is analyzed using a built-in model to calculate key parameters such as the concentration of allulose and the amount of substrate residue in the fermentation broth. A pressure monitor 5 is fixedly connected to the front right side of the outer wall of the monitoring cabinet 8. The model of the pressure monitor 5 is XDY-05. The composition and working principle of the pressure monitor 5 are roughly as follows: a pressure sensor is used as the core component. Common types include capacitive, piezoelectric, and piezoresistive. Capacitive sensors change the distance between the capacitor plates due to pressure changes, thereby generating a change in electrical signal. Piezoresistive sensors utilize the piezoresistive effect of semiconductor materials. Pressure changes will change their resistance value and convert it into an electrical signal. Temperature compensation unit: most sensors integrate a temperature sensor to correct the influence of temperature changes on pressure measurement. Multiple ventilation slots 9 are equidistantly opened on the rear side of the outer wall of the monitoring cabinet 8. Specifically, the fermenter 1 receives the materials required for fermentation through the feed pipe 6 on the left side of its outer wall, enabling convenient material addition. The right side of the outer wall of the fermenter 1 is connected to the vent pipe 7, which can introduce the gas required for fermentation into the fermenter 1. At the same time, its end is connected to the monitoring cabinet 8, which can introduce some gas into the monitoring cabinet 8 to provide a certain degree of regulation for the internal environment of the monitoring cabinet 8. The near-infrared monitor 4 fixed on the left side of the front end of the outer wall of the monitoring cabinet 8 can monitor and analyze the allulose fermentation in the fermenter 1 in real time. The air pressure monitor 5 fixed on the right side of the front end of the outer wall of the monitoring cabinet 8 is used to monitor the air pressure inside the cabinet 8 in real time to ensure that it is within the normal range. Multiple ventilation slots 9 equidistantly opened on the rear side of the outer wall of the monitoring cabinet 8 serve as heat dissipation channels to timely expel the hot air generated by the operation of the air-cooling mechanism 2 and maintain the temperature stability inside the monitoring cabinet 8.

[0021] Working principle: During monitoring, fermentation material is added to fermentation tank 1 through feed pipe 6, and gas is introduced into fermentation tank 1 through vent pipe 7. At the same time, some gas is introduced into monitoring cabinet 8. Near-infrared monitor 4 monitors the fermentation status in fermentation tank 1, and air pressure monitor 5 monitors the air pressure in cabinet 8. During heat dissipation, air cooling mechanism 2 operates, and first motor 2041 starts. Its output end drives connecting rod 2042 to rotate, causing drive wheel 2044 to rotate. Drive wheel 2044 drives driven wheel 2046 to rotate through transmission belt 2045. Due to the moving plate 201 is fixedly connected to the transmission belt 2045 and slides along the column 2048. The column 2048 is fixed on the long short plate 2047. The long short plate 2047 is installed on the long upright plate 2043. When the transmission belt 2045 moves, it drives the moving plate 201 to slide up and down on the right side of the inner wall of the monitoring cabinet 8. Multiple cooling fans 202 on the moving plate 201 are powered by the battery 203 and start. During the movement of the moving plate 201, they provide more comprehensive heat dissipation to the inside of the monitoring cabinet 8. Hot air is discharged through the ventilation groove 9, which avoids the problem of local high temperature in the equipment. After the second motor 3051 in the power assembly 305 starts, its output end drives the worm gear 3052 to rotate. Since the worm gear 3052 is meshed with the rotating short column 303 and the worm wheel 3053 at the top of the threaded lifting rod 301, the worm gear 3052 will synchronously drive the two worm wheels 3053 to rotate, thereby driving the rotating short column 303 and the threaded lifting rod 301 to rotate. When the rotating short column 303 rotates, the multiple crushing blades 304 on its outer wall rotate with it to crush the material in the fermentation tank 1. During the rotation of the threaded lifting rod 301, it generates an upward lifting force on the material through its own thread structure. At the same time, the L-shaped scraper 302 at its bottom rotates with it to scrape the material at the bottom of the inner wall of the fermentation tank 1, realizing the stirring and turning of the material and ensuring that the material is mixed evenly.
