Abstract
Description
Technical Field
[0001] This utility model relates to the field of edible vegetable oil processing technology, and in particular to a device for degrading aflatoxin in edible vegetable oil. Background Technology
[0002] Aflatoxin is a carcinogenic, teratogenic, and mutagenic secondary metabolite secreted by microorganisms such as Aspergillus flavus and Aspergillus parasiticus. Its toxicity is 10 times that of cyanide and 68 times that of arsenic. Aflatoxin is widely found in grains, animal feed, and cooking oils, especially peanuts. This toxin enters the human body directly or indirectly through the food chain, seriously affecting human health.
[0003] Currently, the most common method for degrading aflatoxin in vegetable oils is through ultraviolet (UV) lamp irradiation. However, the UV irradiation process generates high temperatures, which can negatively impact the quality of the vegetable oil and increase its peroxide value. Secondly, in current degradation devices, the vegetable oil is in a static state, and aflatoxin in oil far from the UV lamp cannot be rapidly degraded, thus the processing efficiency needs further improvement. Therefore, to address these shortcomings, this invention proposes a device for degrading aflatoxin in edible vegetable oils. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for degrading aflatoxin in edible vegetable oils.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for degrading aflatoxin in edible vegetable oil, comprising a tank, wherein a first partition, a second partition, and a third partition are fixedly fixed inside the tank from bottom to top, the first partition, the second partition, and the third partition dividing the tank into a bottom cavity, a cooling cavity, and a top cavity, a feeding pipe is fixedly connected to the top of the side wall of the top cavity, a discharge pipe is fixedly fixed to the bottom wall of the bottom cavity, a plurality of vertical pipes are fixedly connected between the first partition and the second partition, and the plurality of vertical pipes connect the bottom cavity and the top cavity, and a controller is installed on the outer wall of the tank;
[0006] Ultraviolet lamps are fixed on both sides of the upper surface of the third partition, a stirring assembly is installed in the middle of the third partition, an outer shell is fixed on the outer wall of the tank, and a food pump connecting the bottom cavity and the top cavity is installed inside the outer shell. The ultraviolet lamps and the food pump are electrically connected to the controller.
[0007] A fan is fixedly installed on one side of the cooling chamber, and an air outlet is opened on the side of the cooling chamber facing the fan. The fan is electrically connected to the controller.
[0008] Furthermore, the third partition is made of a transparent material.
[0009] Furthermore, the stirring assembly includes a motor fixed to the middle of the upper surface of the third partition, and a vertical shaft fixed to the bottom output end of the motor. The vertical shaft passes through the third partition and is fixedly connected to a stirring blade. The vertical shaft and the third partition are rotatably connected through a sealed bearing. The motor is electrically connected to the controller.
[0010] Furthermore, the inlet and outlet of the food pump are respectively fixedly connected to a suction pipe and a discharge pipe, the other end of the suction pipe is connected to the bottom cavity, and the other end of the discharge pipe is connected to the top cavity.
[0011] Furthermore, a valve is installed in the middle of the discharge pipe.
[0012] Furthermore, a dustproof mesh is installed inside the air outlet.
[0013] Furthermore, viewing windows are fixedly installed on the side walls of both the bottom cavity and the top cavity.
[0014] The beneficial effects of this utility model are:
[0015] 1. In use, this utility model is a device for degrading aflatoxin in edible vegetable oil. It is equipped with a tank, the inner part of which is divided into a bottom cavity, a cooling cavity and a top cavity. When the vegetable oil located in the top cavity is irradiated by an ultraviolet lamp, the oil in the bottom cavity is circulated into the top cavity by a food pump, so that the vegetable oil in the bottom cavity and the top cavity are constantly exchanging positions. At the same time, the motor drives the stirring blade to rotate and stir the vegetable oil, ensuring that the ultraviolet lamp can fully and evenly irradiate every part of the vegetable oil, thereby improving the effect of degrading aflatoxin.
[0016] 2. In use, this utility model is a device for degrading aflatoxin in edible vegetable oil. It is equipped with several vertical pipes that connect the bottom cavity and the top cavity. During the process of the vegetable oil flowing back from the top cavity to the bottom cavity, the vegetable oil is cooled by a fan. This achieves the simultaneous degradation of aflatoxin by ultraviolet light and cooling of the vegetable oil, thus preventing the vegetable oil itself from being destroyed by high temperature.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-3 As shown, a device for degrading aflatoxin in edible vegetable oil is disclosed. The device includes a tank 1. Inside the tank 1, a first partition 101, a second partition 102, and a third partition 103 are fixedly arranged from bottom to top. The first partition 101, the second partition 102, and the third partition 103 divide the interior of the tank 1 into a bottom cavity 3, a cooling cavity 4, and a top cavity 5. A feeding pipe 6 is fixedly connected to the top of the side wall of the top cavity 5. A discharge pipe 7 is fixedly connected to the bottom wall of the bottom cavity 3. Several vertical pipes 8 are fixedly connected between the first partition 101 and the second partition 102, and the several vertical pipes 8 connect the bottom cavity 3 and the top cavity 5. A controller 2 is installed on the outer wall of the tank 1.
[0025] Ultraviolet lamps 9 are fixed on both sides of the upper surface of the third partition 103. A stirring assembly is installed in the middle of the third partition 103. An outer shell 13 is fixed on the outer wall of the tank 1. A food pump 14 connecting the bottom cavity 3 and the top cavity 5 is installed inside the outer shell 13. The ultraviolet lamps 9 and the food pump 14 are electrically connected to the controller 2.
[0026] A fan 15 is fixedly installed on one side of the cooling chamber 4, and an air outlet 16 is opened on the side of the cooling chamber 4 facing the fan 15. The fan 15 is electrically connected to the controller 2.
[0027] In this embodiment, the controller 2 is a Mitsubishi FX1N model, which can control the operation of the fan 15, the food pump 14 and the stirring assembly.
[0028] The third partition 103 is made of transparent material.
[0029] In this embodiment, the third partition 103 is made of a transparent plate, regardless of the material, so that the light from the ultraviolet lamp 9 can pass through the third partition 103 to irradiate the vegetable oil in the top cavity 5.
[0030] The stirring assembly includes a motor 10 fixed to the middle of the upper surface of the third partition 103, and a vertical shaft 11 fixed to the bottom output end of the motor 10. The vertical shaft 11 passes through the third partition 103 and is fixedly connected to the stirring blade 12. The vertical shaft 11 and the third partition 103 are rotatably connected through a sealed bearing. The motor 10 is electrically connected to the controller 2.
[0031] The controller 2 controls the motor 10 to start, and the motor 10 drives the stirring blade 12 to rotate. The stirring blade 12 stirs the vegetable oil inside the top cavity 5. The stirring blade 12 adopts a propeller-type stirrer, which makes the vegetable oil continuously roll in the top cavity 5, thus facilitating the uniform irradiation of the vegetable oil by the ultraviolet lamp 9.
[0032] The inlet and outlet of the food pump 14 are respectively fixedly connected to a suction pipe 141 and a discharge pipe 142. The other end of the suction pipe 141 is connected to the inside of the bottom cavity 3, and the other end of the discharge pipe 142 is connected to the inside of the top cavity 5.
[0033] The food pump 14 can continuously extract the vegetable oil from the bottom cavity 3 and then inject it into the top cavity 5 through the drain pipe 142. The vegetable oil in the top cavity 5 then flows back into the bottom cavity 3 along the vertical pipe 8, so that the vegetable oil in the bottom cavity 3 and the top cavity 5 can constantly change positions, which is more conducive to the uniform irradiation of the vegetable oil by the ultraviolet lamp 9.
[0034] A valve is installed in the middle of the discharge pipe 7.
[0035] Vegetable oil can be added into the tank 1 through the feeding pipe 6, and the vegetable oil can be discharged along the discharge pipe 7 by opening the valve on the discharge pipe 7.
[0036] A dust filter 17 is installed inside the air outlet 16.
[0037] The dustproof net 17 can prevent external dust from entering the cooling chamber 4.
[0038] Viewing windows 18 are fixedly installed on the side walls of both the bottom cavity 3 and the top cavity 5.
[0039] In this embodiment, when the vegetable oil is irradiated by the ultraviolet lamp 9, a light-blocking cloth can be covered with the viewing window 18. Opening the light-blocking cloth allows observation of the state of the vegetable oil inside through the viewing window 18.
[0040] Working principle: First, vegetable oil is added into the tank 1 through the feeding pipe 6. During addition, the liquid level is observed through the upper viewing window 18, ensuring it is below the drain pipe 142. Then, the ultraviolet lamp 9, motor 10, food pump 14, and fan 15 are activated. Under the action of the food pump 14, the vegetable oil flows from the bottom cavity 3 along the suction pipe 141 and drain pipe 142 into the top cavity 5. The vegetable oil in the top cavity 5 then flows back to the bottom cavity 3 along the vertical pipe 8, causing continuous circulation. The motor 10 drives the stirring blade 12 to rotate, agitating the vegetable oil and ensuring that the ultraviolet lamp 9 irradiates the oil evenly, degrading aflatoxin in the vegetable oil. As degradation progresses, the temperature of the vegetable oil rises. Because the vegetable oil continuously flows along the vertical pipe 8, the fan 15 cools the oil passing through the vertical pipe 8. After complete degradation, the valve on the drain pipe 7 is opened, and the vegetable oil is discharged along the drain pipe 7.
