Description

Technical Field

[0001] This utility model relates to the technical field of equipment for detecting microorganisms on the surface of baked goods, and specifically to an integrated device for in-situ sampling and detection of microorganisms on the surface of baked goods. Background Technology

[0002] Baked goods are convenience foods made from flour, yeast, salt, sugar, and water as basic ingredients, with the addition of appropriate amounts of oil, dairy products, eggs, and additives. After production, factories use microbial testing devices to detect microorganisms on the surface of baked goods to ensure food safety. Baked goods include biscuits, bread, and puff pastries.

[0003] Currently, most integrated devices for in-situ sampling and detection of microorganisms on the surface of baked goods typically use sampling swabs to wipe the surface of the baked goods, then fully release the microbial sample from the swab into a sampling solution, dilute the sampling solution to obtain a detection solution, and place the detection solution into the device's detection tank to detect microorganisms. However, when the device detects microorganisms on the surface of biscuits, because biscuits are crisp and have a relatively loose structure, they easily crumble after baking and cooling, resulting in a large number of small fragments on the biscuit surface. When traditional devices are used for sampling, the sampling swab will collect the fragments along with the biscuit fragments. The biscuit fragments will adhere to the swab fibers, wrapping or blocking the microorganisms. During subsequent sample elution and dilution, the microorganisms are difficult to fully release into the detection solution, resulting in lower detection results and inaccurate data from the device. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an integrated device for in-situ sampling and detection of microorganisms on the surface of baked goods, which can effectively solve the problems mentioned in the background technology.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] This utility model provides a technical solution: such as Figure 1 - Figure 5As shown, in this embodiment, the integrated device for in-situ sampling and detection of microorganisms on the surface of baked goods includes: a workbench 1, an XYZ axis sliding stage 13 mounted on one side of the upper end of the workbench 1, a mounting platform mounted on the Z-axis of the XYZ axis sliding stage 13, a sampling swab 14 clamped onto the mounting platform, a conveyor belt 15 disposed below the XYZ axis sliding stage 13, the conveyor belt 15 mounted on the workbench 1, a detection device 11 mounted on the other side of the upper end of the workbench 1, and an extension device fixedly connected to the other side of the workbench 1. Plate 2, one side of extension plate 2 is equipped with cylinder 21, one end of the telescopic rod of cylinder 21 is fixedly connected to sliding frame 22, one side of sliding frame 22 is fixedly connected to blower frame 23, the inner wall of blower frame 23 is equipped with fan 24, one side of the inner wall of blower frame 23 is slidably connected to sliding strip 26, one side of sliding strip 26 is rotatably connected to multiple rotating blocks 28, one side of each of the multiple rotating blocks 28 is fixedly connected to reversing blades 25, and both ends of the multiple reversing blades 25 are rotatably connected to the inner wall of blower frame 23.

[0020] The biscuits produced in the factory are transported to the sampling area via conveyor belt 15. Cylinder 1 21 is activated, causing the sliding frame 22 to slide on the extension plate 2. The air blower 23 is aligned with the biscuits, and fan 24 is turned on. Simultaneously, cylinder 27 is activated, causing the sliding strip 26 to slide within the air blower 23. This causes the reversing blades 25 to rotate within the air blower 23, adjusting the direction of the blown air and increasing the blowing range. This allows the air blown by fan 24 to remove crumbs from the biscuits. This structural design prevents small crumbs from remaining on the biscuit surface, ensuring that microorganisms on the sampling swab 14 are fully released into the detection liquid, guaranteeing accurate data from the equipment.

[0021] It is important to note that the equipment performs microbial testing through sampling. After sampling, the conveyor belt 15 continues to transport the biscuits. After the sampling swab 14 completes the testing of the biscuits, the biscuits are removed from the conveyor belt 15. Once the biscuits pass the test, they are placed back on the conveyor belt 15. The conveyor belt 15 is part of the factory production line. The freshly produced biscuits pass through the conveyor belt 15, enabling the equipment to perform in-situ sampling and ensuring the accuracy of the test. The rotating block 28 is located at one end of the reversing blade 25 and near the edge. The sliding bar 26 moves, pulling the rotating block 28, causing the reversing blade 25 to rotate. The XYZ axis sliding table 13 drives the sampling swab 14 to move, moving it in a grid pattern on the biscuits for sampling.

[0022] like Figure 3 and Figure 4 As shown, a cylinder 27 is installed on one side of the blower frame 23, one end of the sliding bar 26 extends out of the blower frame 23, and one end of the telescopic rod of the cylinder 27 is fixedly connected to one end of the sliding bar 26; by opening the cylinder 27, the sliding bar 26 is pulled or pushed to slide inside the blower frame 23, so that multiple reversing blades 25 rotate simultaneously, changing the direction of the air blown out by the fan 24.

[0023] like Figure 3 As shown, a sliding frame 4 is fixedly connected to the upper end of the blower frame 23, and a filter screen 41 is slidably connected to the inner wall of the sliding frame 4. The filter screen 41 is used to filter the gas entering the blower frame 23 to prevent dust in the air blown out by the fan 24 from contaminating the biscuits. At the same time, the filter screen 41 slides in the sliding frame 4, making it easy to remove the filter screen 41.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, collection boxes 3 are provided on both sides of the conveyor belt 15, and mounting slots are provided on both sides of the upper end of the workbench 1. The two collection boxes 3 are respectively installed in the two mounting slots. After adjusting the direction of the air blown out by the fan 24 by multiple reversing blades 25, the small crumbs on the biscuits are blown to both sides of the conveyor belt 15, and the two collection boxes 3 collect the crumbs to prevent the crumbs from being blown onto the workbench 1 and affecting the subsequent operation of the staff.

[0025] like Figure 5 As shown, a fixing plate 33 is fixedly connected to one side of the collection box 3, and a fixing column 32 is provided on the other side of the collection box 3. The lower end of the fixing column 32 is fixedly connected to the upper end of the workbench 1. A rotating rod 31 is rotatably connected to the outer surface of the fixing column 32, and the rotating rod 31 abuts against the fixing plate 33. By rotating the rotating rod 31, the rotating rod 31 is removed from the fixing plate 33, and the restriction of the collection box 3 is released, so that the collection box 3 can be removed from the equipment for cleaning. This structural design improves the convenience of using the equipment.

[0026] like Figure 1 and Figure 2 As shown, a dispensing station 12 is fixedly connected to the upper middle part of the workbench 1; the dispensing station 12 is used by staff to wash and dilute the microorganisms collected by the sampling swab 14 into a test solution.

[0027] like Figure 1 and Figure 2 As shown, the upper end of the extension plate 2 is fixedly connected to the guide rail 5, and the outer surface of the guide rail 5 is slidably connected to one end of the sliding frame 22; the guide rail 5 is used to limit the sliding direction of the sliding frame 22 and ensure that the blower frame 23 is aligned with the biscuit being detected on the conveyor belt 15.

[0028] This utility model provides an integrated device for in-situ sampling and detection of microorganisms on the surface of baked goods. The specific working principle is as follows: When performing microbial testing on the surface of cookies baked in the factory, the conveyor belt 15 transports the cookies produced in the factory to the sampling area. Cylinder 1 21 is activated, the sliding frame 22 slides on the extension plate 2, the blower frame 23 is aligned with the cookie, and the fan 24 is turned on. Simultaneously, cylinder 27 is activated, and the sliding bar 26 slides within the blower frame 23, causing the reversing blades 25 to rotate within the blower frame 23, adjusting the direction of the blown air and increasing the blowing range. This allows the air blown by the fan 24 to blow away crumbs from the cookie. Cylinder 1 21 is then activated in the reverse direction, moving the sliding frame 22 to its initial position. The XYZ axis sliding stage 13 is then activated, and the sampling swab 14 is moved onto the cookie for wiping and sampling. After sampling, the sampling swab 14 is removed from the XYZ axis sliding stage 13. The sampling swab 14 is then washed and diluted by the staff to obtain a test solution, which is placed in the detection tank within the detection equipment 11. The detection equipment 11 then performs the test, detecting the microorganisms on the cookie surface.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
