[0002] Aflatoxin is a metabolite of Aspergillus flavus and Aspergillus parasiticus, and is widely present in nature. When the aflatoxin content in feed is greater than 1 ppm, it can cause poisoning and death of the livestock and poultry being fed. Aflatoxin poisoning is more common in pigs and chickens, followed by ducks and cattle.

[0003] Aflatoxins can cause a variety of diseases, such as acute liver failure, liver necrosis, cerebral edema, lung disease. Aflatoxins in nature mostly come from moldy components in grains (such as corn, rice, wheat, sorghum, etc.) and nuts (peanuts, almonds, sunflower seeds, etc.). They also exist in feeds prepared from these crops and in the bodies of poultry and livestock fed with feeds. Therefore, mold detection in feed production is very important.

[0031] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figures 1-5 show a device for mycotoxin detection of biological feed, including a main transmission belt 1 and a secondary transmission line 2, wherein the main transmission belt 1, the secondary transmission line 2, a plurality of transfer devices and a pressure sensor are all connected to a conveying control module;

Transfer equipment is installed in the lighting black box and the inspection equipment group 4. The transfer equipment includes a short transmission belt. A stepper motor is installed at the power input end of the short transmission belt. The transfer equipment rotates and then transmits the feed, so that the feed basket on it can switch the transportation line.

[0036] The sampling device is installed at the movable end of the robotic arm. The sampling device includes an electronic weighing spoon. The input end of the crushing and extraction device 9 is matched with the sampling device. The sampling device is moved by the robotic arm to take samples. The sampling device can be accurately moved to the positioning point, and the sampling device can weigh and record the sampling amount, which is convenient for the subsequent sampling amount replenishment of qualified products.

[0037] An electric gate is installed in the feeding pipe, a weighing device is installed on the upper end of the electric gate, and a quantitative feeding device is installed between the top of the feeding pipe and the storage tank. The feed stored in the storage tank is fed to the electric gate through the quantitative feeding device, and the feed is weighed by the weighing device until the weighed value is equal to the sampling weight of the sampling device. The feeding is stopped, and the electric gate is opened at this time to allow the output feed to fall along the feeding pipe into the feed frame.

[0038] See also Figure 6-7 The crushing and extraction equipment 9 includes a rapid grinder, the output end of the rapid grinder is connected to a burette, the output end of the burette is equipped with a dropper and a discharge pipe with an electromagnetic opening and closing valve, the detection equipment includes a mycotoxin detector, and the detection input end of the mycotoxin detector is equipped with a detection card self-filling device 8, and the crushing and extraction equipment 9 is connected to an automatic disinfection and cleaning structure.

[0039] The detection card self-filling device 8 includes an electric guide rail matching the detection device 7, on which a detection card box is installed, and an electric push rod is installed at one end of the detection card box, and the movable end of the electric push rod is inserted into the lower end of the detection card box. The lower end of the detection card box is provided with a sliding hole matching the detection input end of the detection device. The detection card self-filling device 8 can push the detection card therein to the bottom of the drip tube, and the detection card collection port can be quickly inserted into the detection device 7 for detection after the detection is completed. After the detection is completed, the detection card self-filling device 8 and the electric push rod can be controlled to work so that the detected detection card falls into the recovery hole.

[0040] The automatic disinfection and cleaning structure includes a water pipe connected to the input end of the rapid grinder, a vertical displacement cylinder matching the crushing and extraction device 9 is installed in the detection room, the detection card self-filling device 8 and the detection device are both installed on the workbench 6 in the detection room, a recovery hole is opened on the workbench 6, and the recovery hole is located between the detection card self-filling device 8 and the detection device, an inclined net is installed in the recovery hole, a solid recovery chamber is provided at one end of the inclined net, a liquid recovery pipe is installed at the lower end of the inclined net, and two through holes are opened in the middle of the inclined net; the detection card is introduced into the solid recovery chamber through the inclined net, and after the crushing and extraction device 9 is driven downward by the vertical displacement cylinder, the drip tube and the drain pipe are respectively inserted into the two through holes, and at this time, when water is passed into the crushing and extraction device 9 for cleaning, the discharged water is directly discharged into the liquid recovery pipe.

[0041] Second implementation method:

[0042] As shown in Figure 3-5, it also includes a detection and control system, which includes a control cabinet with a processor installed in it, a conveying control module and a preliminary screening module connected to the processor, and 4 groups of actual inspection equipment and sampling compensation equipment are all connected to the processor signal; an image processing unit and an image analysis unit are provided in the preliminary screening module, and a UV camera is connected to the preliminary screening module.

[0043] The image analysis unit is used to analyze the number of light spots in the image and locate the light spot positions. The image analysis unit can generate light spot coordinate points according to the image, so that the processor can drive the robot arm to work according to the coordinate points.

[0044] When this solution is used, the ultraviolet camera in the initial detection device 3 takes ultraviolet photos of the feed frame. After the collected image is processed, it is analyzed whether there is a fluorescent spot distribution on it; if not, the transfer device works to transfer the feed frame to the main transmission belt 1.

[0045] If it exists, mark the position with more light spots, and send a signal to the inspection equipment group 4 to control the transfer equipment in the primary detection equipment 3 to transfer the feed frame to the secondary transmission line 2. The feed frame is transported to the inspection equipment group 4 through the secondary transmission line 2;

[0046] The sampling equipment in the actual inspection equipment group 4 performs quantitative sampling on the feed frame, and the electronic weighing spoon records the sampling amount. The sampling point is the light spot coordinate position obtained by the image analysis unit analysis. The sampling equipment is moved to the light spot coordinate position by the mechanical arm. After sampling, the sample is transferred to the crushing and extraction equipment 9. The feed extract is obtained by the crushing and extraction equipment 9. After the feed extract is dripped on the test card output by the test card self-filling device 8 by the crushing and extraction equipment 9, the test card self-filling device 8 inserts the test card into the detection device 7;

[0047] Performing mold detection on the feed extract by using the detection device 7 to determine whether there is mold therein;

[0048] If mold is present, the transfer device will work to discharge the feed frame out of the secondary transmission line 2;

[0049] If it does not exist, the sample compensation device 5 works to compensate the feed frame for feed, and the compensation amount is the sampling amount recorded by the electronic weighing spoon, and then the secondary transmission line 2 continues to work to return the feed frame to the main transmission belt 1;

[0050] This solution can be achieved by testing the feed in batches before packaging to ensure that there is no mold in the feed that is subsequently packaged. The feed can be batched in advance to facilitate the subsequent feed packaging work. The testing includes initial screening and actual inspection. Feed that passes the actual inspection can quickly supplement the sampling and extraction volume and return to the transportation line, effectively ensuring production efficiency and product quality.
