Description

Technical Field

[0001] This utility model relates to the technical field of aflatoxin degradation devices, specifically an aflatoxin degradation device. Background Technology

[0002] Aflatoxin (AF) is mainly a metabolite of Aspergillus flavus and Aspergillus parasiticus. It has strong toxicity and carcinogenicity. Aflatoxin is most likely to contaminate food, especially foods with high starch content, such as corn flour. Corn flour may contain aflatoxin when improperly stored or when it becomes damp and moldy. Consuming corn flour contaminated with aflatoxin can harm human health. Studies have shown that Bacillus has a certain ability to degrade aflatoxin in vitro.

[0003] Currently, in existing technologies, aflatoxin in corn flour is degraded using a high-temperature drum degradation machine. A heating device is used below the drum to heat it to over 280 degrees Celsius, thereby destroying the molecular structure of aflatoxin. However, this process damages the corn flour itself. Therefore, there is a need to propose an aflatoxin degradation device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, such as the problem that high-temperature drum degradation machines can easily damage corn flour itself during the degradation of aflatoxin in corn flour, this invention proposes an aflatoxin degradation device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an aflatoxin degradation device, including a shell, a reaction tank fixedly connected to the inner cavity of the shell, a cover plate provided on the top of the reaction tank, a ventilation pipe provided on one side of the top of the cover plate, a negative pressure suction machine provided on one side of the shell, a two-stage degradation mechanism provided in the inner cavity of the reaction tank, and a controller provided on one side of the outer wall of the shell; The two-stage degradation mechanism includes a motor, which is fixedly connected to the top of the cover plate. The output end of the motor passes through the bottom of the cover plate and is fixedly connected to a stirring shaft. A heating pipe is provided on the outside of the reaction tank, and a cooling pipe is provided in the inner cavity of the reaction tank. A water pump is provided at one end of the cooling pipe. A temperature sensor is provided in the inner cavity of the reaction tank. An ultrasonic vibrating rod is provided on the top of the cover plate, and a high-intensity lamp is provided at the bottom of the cover plate.

[0006] Preferably, a cavity is provided between the shell and the reaction vessel, and the heating tube is fixedly connected to one side of the cavity.

[0011] Preferably, the high-intensity light is fixedly connected to the bottom of the cover plate, and the high-intensity light is set at an angle.

[0012] As a preferred option, the weighted option is used.

[0013] The advantages of this utility model are: This invention introduces a fermentation broth containing Bacillus and pulverized moldy corn flour into a reaction tank. A two-stage degradation mechanism is used for efficient and non-destructive degradation. First, a motor-driven stirring shaft stirs the corn flour mixture. The Bacillus in the fermentation broth grows and degrades aflatoxin simultaneously, with the temperature controlled at around 37 degrees Celsius. After 48 hours of mixing, the degradation capacity of the Bacillus decreases. To prevent further Bacillus cultivation from consuming the corn flour, a strong light is used to irradiate the corn flour mixture and raise the temperature to 70 degrees Celsius, inactivating the Bacillus. Then, an ultrasonic vibrator and a strong light are used in conjunction for physical degradation, achieving a two-stage degradation effect. This solves the problem that high-temperature drum degradation machines easily damage the corn flour itself during aflatoxin degradation process. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses an aflatoxin degradation device. (Refer to...) Figures 1-5 A device for degrading aflatoxin includes a shell 1, a reaction vessel 2 fixedly connected to the inner cavity of the shell 1, a cover plate 21 on the top of the reaction vessel 2, a ventilation pipe 22 on one side of the top of the cover plate 21, a negative pressure suction machine 12 on one side of the shell 1, a two-stage degradation mechanism 3 in the inner cavity of the reaction vessel 2, and a controller 4 on one side of the outer wall of the shell 1. Fermentation broth containing Bacillus and pulverized moldy corn flour are introduced into the reaction vessel 2, and the two-stage degradation mechanism 3 performs efficient and non-destructive degradation. The controller 4 works in conjunction with the two-stage degradation mechanism 3 to control the temperature and the two-stage degradation process within the reaction vessel 2. First, the corn flour mixture is stirred, and the Bacillus in the fermentation broth grows and degrades aflatoxin simultaneously. During this process, the temperature is controlled at 37 degrees Celsius. This is a biodegradation process. After 48 hours of mixing, the Bacillus... The degradation capacity of the corn flour decreases. In order to avoid the corn flour being consumed by the continued cultivation of Bacillus, strong light is used to irradiate the corn flour mixture and raise its temperature to 70 degrees Celsius. At this time, the Bacillus is inactivated. Then, physical degradation is carried out. After the degradation is completed, the corn flour is dried and a portion of the corn flour is taken out by the negative pressure suction machine 12 for sampling and testing. After the corn flour is qualitatively tested and found to be free of aflatoxin, the entire corn flour is taken out by the negative pressure suction machine 12. This achieves the purpose of efficient and non-destructive degradation of aflatoxin in corn flour. The negative pressure suction machine 12 used in this embodiment is existing technology. Its basic principle is to form a negative pressure in the pipeline by a vacuum pump and use the air pressure difference to suck the corn flour into the suction machine. When the external atmospheric pressure pushes the corn flour into the suction machine, the corn flour enters the filter chamber through the hose. The air and corn flour are separated here. Finally, the corn flour is delivered out of the suction machine. The two-stage degradation mechanism 3 includes a motor 31, which is fixedly connected to the top of the cover plate 21. The output end of the motor 31 passes through the bottom of the cover plate 21 and is fixedly connected to a stirring shaft 32. A heating pipe 33 is installed on the outside of the reaction tank 2, and a cooling pipe 34 is installed inside the reaction tank 2. A water pump 35 is installed at one end of the cooling pipe 34. A temperature sensor 37 is installed inside the reaction tank 2. An ultrasonic vibrator 38 is installed on the top of the cover plate 21, and a high-intensity lamp 39 is installed at the bottom of the cover plate 21. By introducing fermentation broth containing Bacillus spores and crushed moldy corn flour into the reaction tank 2, biodegradation is carried out first. The stirring shaft 32 driven by the motor 31 is used to stir the corn flour mixture and make it fully mixed. The Bacillus spores in the fermentation broth grow and degrade aflatoxin at the same time. At this time, the temperature inside the reaction tank 2 is controlled at about 37 degrees Celsius. After 48 hours of mixing, the degradation capacity of Bacillus reaches its upper limit and begins to decline. To prevent the continued cultivation of Bacillus from consuming corn flour, a strong light 39 is used to irradiate the mixture and raise the internal temperature of the reaction vessel 2 to 70 degrees Celsius, at which point the Bacillus is inactivated. Then, physical degradation is carried out using an ultrasonic vibrator 38 and a strong light 39 in combination until the degradation is complete. The strong light from the strong light 39 will destroy the molecular structure of aflatoxin and reduce its toxicity. The high-frequency vibration generated by the ultrasonic vibrator 38 will destroy the molecular structure of aflatoxin, thereby degrading it. The controller 4 works with the heating tube 33 to heat the mixture. The controller 4 works with the water pump 35 and the cooling tube 34 to cool the mixture. The temperature sensor 37 is used to detect the temperature inside the reaction vessel 2 in real time. In conjunction with the heating tube 33 and the cooling tube 34, precise temperature control can be achieved.

[0019] Reference Figure 2 , Figure 4 and Figure 5 A cavity 11 is provided between the shell 1 and the reaction vessel 2. A heating pipe 33 is fixedly connected to one side of the cavity 11. One end of a cooling pipe 34 extends through to the outside of the reaction vessel 2 and is fixedly connected to one side of a water pump 35. The water pump 35 is fixedly connected to the side wall of the shell 1. One end of the cooling pipe 34 is provided with a water outlet 36, which extends to the outside of the reaction vessel 2. One end of a ventilation pipe 22 extends into the inner cavity of the reaction vessel 2, and a filter 23 is inserted into the other end of the ventilation pipe 22. The ventilation of the reaction vessel 2 is improved by the ventilation pipe 22 on the cover plate 21, which facilitates the internal ventilation of the reaction vessel 2. Air is exchanged with the outside air. A filter 23 is installed at one end of the ventilation pipe 22 to prevent impurities in the outside air from entering the interior of the reaction tank 2 and contaminating the corn flour. The heating pipe 33 in the cavity 11 is controlled by the controller 4 to heat the reaction tank 2. The heat from the heating pipe 33 raises the internal temperature of the reaction tank 2. The temperature is detected in real time by the temperature sensor 37. When the temperature is too high, the water pump 35 is controlled by the controller 4 to introduce external cold water. The cold water carries away some of the heat through the cooling pipe 34 and is then discharged from the outlet 36, thereby achieving the purpose of controlling the temperature inside the reaction tank 2.

[0020] Reference Figure 1 , Figure 2 and Figure 3 One end of the ultrasonic vibrating rod 38 is fixedly connected to the top of the cover plate 21, and the other end of the ultrasonic vibrating rod 38 extends into the inner cavity of the reaction vessel 2. The high-intensity lamp 39 is fixedly connected to the bottom of the cover plate 21 and is tilted. The high-intensity lamp 39 irradiates the corn flour mixture. The strong light of the high-intensity lamp 39 can destroy the molecular structure of aflatoxin and reduce its toxicity. At the same time, the high-frequency vibration of the two ultrasonic vibrating rods 38 can destroy the molecular structure of aflatoxin and thus accelerate its degradation.

[0021] Working Principle: During operation, the fermentation broth containing Bacillus and crushed moldy corn flour are first introduced into reaction tank 2. A two-stage degradation mechanism 3 first performs biodegradation, then physical degradation. The motor 31 on the cover plate 21 drives the stirring shaft 32 to stir the corn flour mixture, cultivating Bacillus growth and degrading aflatoxin. Meanwhile, the controller 4 on one side of the shell 1 controls the heating tube 33 inside the cavity 11 to raise the temperature inside reaction tank 2 to 37 degrees Celsius. A temperature sensor 37 monitors the temperature in real time. If the temperature is too high, the controller 4 controls the water pump 35 to introduce external cold water. The cold water absorbs some heat after passing through the cooling pipe 34 and is discharged from the outlet 36, thus maintaining the temperature inside reaction tank 2 at 37 degrees Celsius. During this process, the biodegradation... After 48 hours, the degradation of aflatoxin reaches 50%. To prevent the continued growth of Bacillus from consuming corn flour, a strong light 39 is used to irradiate the corn flour mixture and control the temperature inside the reaction tank 2 to maintain it at 70 degrees Celsius, thus inactivating the Bacillus. The ultrasonic vibrator 38 is used in conjunction with the strong light 39 for physical degradation, achieving efficient and non-destructive degradation of aflatoxin in the corn flour. After degradation, the corn flour is dried and then a portion is drawn out by the negative pressure suction machine 12 for sampling and testing. After qualitative testing confirms that the corn flour does not contain aflatoxin, the negative pressure suction machine 12 is used to draw out all the corn flour. The ventilation pipe 22 and the filter 23 work together to improve air exchange between the inside and outside of the reaction tank 2 during the degradation process and prevent external impurities from entering the reaction tank 2.
