Description

Technical Field

[0001] This invention belongs to the field of sampling equipment technology, specifically relating to a rapid and aseptic sampling device for food safety testing. Background Technology

[0002] Food testing refers to the technology of detecting and studying the substances in food and their changes, including the analysis of food nutritional components, the analysis of pollutants in food, the analysis of food additives, and the analysis of harmful substances in food. As residents become increasingly aware of food safety, restaurants, supermarkets, and other places that sell food are required to retain samples of the food they sell for inspection by testing departments.

[0003] Sampling, also known as sampling, is the process of representing a continuous analog quantity using discrete points. It involves extracting amplitude samples of a continuous signal on a time axis at regular intervals. Aseptic means the absence of live bacteria and is an important concept in biotechnology. Only when the culture medium, fermentation equipment, etc., are aseptic can pure culture be achieved after microbial inoculation, ultimately yielding the desired product. Methods to prevent microorganisms from entering the body or objects are called aseptic operations or aseptic techniques.

[0004] One current problem is that when changing samples in the sampling equipment, the sampling head needs to be replaced manually, which is inefficient and can also cause blockages during the sampling process. Summary of the Invention

[0005] In view of the problems mentioned in the background art above, the purpose of this invention is to provide a food testing safety, rapid, and aseptic sampling device.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A rapid and aseptic sampling device for food safety testing includes a mounting frame, an electrical control box mounted on the mounting frame, a first motor mounted inside the electrical control box, a turntable mounted on the output end of the first motor, and a plurality of placement openings evenly arranged in a ring on the turntable, with sample tubes placed in the placement openings.

[0008] The sample tube includes a tube body, an inlet nozzle is slidably installed at the end of the tube body, and a hollow bracket is installed inside both the tube body and the inlet nozzle. A spring is installed between the upper and lower hollow brackets.

[0009] An installation box is mounted on the side of the electrical control box, and a mating groove is provided at the bottom of the installation box, with a sample outlet inside the mating groove;

[0010] The mounting box is equipped with a guide rail on its side, and a slide table is slidably mounted on the guide rail. A sampling cylinder is mounted on the slide table, and a crushing tooth is provided inside the sampling cylinder. A second motor is mounted on the slide table, and a crushing roller that meshes with and matches the crushing tooth is connected to the output end of the second motor. A telescopic cylinder with its output end connected to the slide table is mounted on the mounting box. A sampling tube is connected between the slide table and the mounting box, and the input end of the sampling tube extends through the sampling cylinder.

[0011] The installation box is equipped with a self-destructive germ-killing mechanism;

[0012] The sterilization mechanism includes a mounting plate, on which a third motor is mounted. The output end of the third motor is connected to a right-angle bracket. Filter plates are mounted on both ends of the right-angle bracket. A partition cavity is mounted on the mounting plate. A sample outlet tube is connected between the partition cavity and the sample outlet. The partition cavity is connected to the output end of the sample tube. A sterilization chamber is installed in a ring on each side of the mounting plate and the partition cavity. The sterilization chamber is located within the stroke range of the right-angle bracket. Both the partition cavity and the sterilization chamber have openings of a size matching the filter plates.

[0013] The mounting bracket is equipped with a suction device that communicates with the partition cavity.

[0014] Furthermore, the suction device includes a fourth motor mounted on the mounting bracket, and the output end of the fourth motor is connected to a suction impeller located inside the mounting box. This design achieves the purpose of suction.

[0015] Furthermore, the depth of the placement opening is three centimeters, a design that ensures the stability of the sample tube placement.

[0016] Furthermore, the end of the feed nozzle is truncated cone-shaped. This design can guide the feed nozzle when it is touched, thereby compressing it.

[0017] Furthermore, the sterilization chamber is filled with sterilizing liquid, and a micro pump is installed at the bottom of the sterilization chamber. The output end of the micro pump is connected to a nozzle. With this design, starting the micro pump can sterilize the filter plate and prevent cross-infection after replacement.

[0018] Furthermore, a baffle is installed inside the partition cavity. This design can better block the pulverized sample and allow it to fall into the sample outlet tube.

[0019] Furthermore, sealing rings are installed on both the upper and lower sides of the filter plate. This design ensures airtightness and prevents splashing.

[0020] Furthermore, the sampling tube is a steel wire sampling tube, a design that prevents it from collapsing even under the suction of the suction device.

[0021] Furthermore, the sampling tube has an internal coating, a design that ensures a smooth surface and the fluidity of the pulverized sample.

[0022] The beneficial effects of using the present invention are as follows:

[0023] The structural design of this invention enables automatic sampling, automatic filter plate replacement and cleaning, rapid restart when changing samples, and prevents filter plate clogging through the cleaning process. Attached Figure Description

Detailed Implementation

[0035] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] like Figures 1-5 As shown, a food safety rapid aseptic sampling device of the present invention includes a mounting frame 1, an electrical control box 2 mounted on the mounting frame 1, a first motor 3 mounted inside the electrical control box 2, a turntable 4 mounted on the output end of the first motor 3, and a plurality of placement ports 5 evenly mounted in a ring on the turntable 4, with sample tubes 6 placed in the placement ports 5.

[0037] The sample tube 6 includes a tube body 61, an inlet nozzle 62 is slidably installed at the end of the tube body 61, and hollow brackets 63 are installed inside both the tube body 61 and the inlet nozzle 62. A spring 64 is installed between the upper and lower hollow brackets 63.

[0038] The electrical control box 2 has an installation box 7 installed on its side. The bottom of the installation box 7 is provided with a mating groove 8, and a sample outlet 9 is provided in the mating groove 8.

[0039] The mounting box 7 is equipped with a guide rail 10 on its side. A slide table 11 is slidably mounted on the guide rail 10. A sampling cylinder 12 is mounted on the slide table 11. The sampling cylinder 12 is equipped with crushing teeth 13. A second motor 14 is mounted on the slide table 11. The output end of the second motor 14 is connected to a crushing roller 15 that meshes with and matches the crushing teeth 13. The mounting box 7 is equipped with a telescopic cylinder 16 whose output end is connected to the slide table 11. A sampling tube 17 is connected between the slide table 11 and the mounting box 7. The input end of the sampling tube 17 extends through the sampling cylinder 12.

[0040] The installation box 7 contains a self-destructive germ mechanism 18;

[0041] The sterilization mechanism 18 includes a mounting plate 181, on which a third motor 182 is mounted. The output end of the third motor 182 is connected to a right-angle bracket 183. Filter plates 184 are mounted on both ends of the right-angle bracket 183. A partition cavity 185 is mounted on the mounting plate 181. A sample outlet tube 186 is connected between the partition cavity 185 and the sample outlet 9. The partition cavity 185 is connected to the output end of the sampling tube 17. A sterilization chamber 187 is installed in a ring on both sides of the mounting plate 181 and the partition cavity 185. The sterilization chamber 187 is located within the stroke range of the right-angle bracket 183. Both the partition cavity 185 and the sterilization chamber 187 are provided with openings 188 of matching size to the filter plates 184.

[0042] Mounting bracket 1 is equipped with a suction device 19 that communicates with partition cavity 185.

[0043] In this implementation case, when using a food safety rapid aseptic sampling device, the telescopic cylinder 16 operates, driving the slide table 11 to move on the guide rail 10, thereby achieving the purpose of inserting the sampling cylinder 12 into the sample. The second motor 14 operates, driving the crushing roller 15 to rotate, which, together with the crushing teeth 13, achieves the crushing process of the sample, making it easy to move in windy conditions.

[0044] Under the effect of wind, the sample enters the partition chamber 185 after passing through the sampling tube 17. Under the obstruction of the filter plate, it enters the outlet tube 186 and then the sample tube 6. When the sample tube 6 is filled with sample for a set time, each station stops operating, the first motor 3 runs, and drives the turntable 4 to rotate. The sample tube 6, which is placed in the placement port 5 for circulation, moves accordingly. When the feed cone 62 of the sample tube 61 collides with the mating groove 8, under the action of the force of continued movement, the feed nozzle 62 moves into the tube body 61, that is, compresses the spring 64. When the feed nozzle 62 moves to the position of the outlet 9, the first motor 3 stops running. Under the action of the spring 64, the feed nozzle 62 is inserted into the outlet 9 to achieve connection. Similarly, the sample tube 6 comes out of the outlet 9, which is also driven by the force of the first motor 3, forcing the feed nozzle 62 to be pressed into the tube body 61, thereby achieving the detachment.

[0045] Under the effect of the suction device 19, the pulverized sample accumulates on the lower side of the separation chamber 185 under the effect of the filter plate 184. Under its own weight, it is transported by the sample outlet pipe 186 to the sample tube 6 located at the sample outlet 9. It should be noted that, according to actual needs, a suction device can be installed at the output end of the sample outlet pipe 186 to speed up the flow of the sample into the sample tube 6. This point is easy for those in the relevant field to understand.

[0046] When it is necessary to replace the sample or clean the filter plate 184, the third motor 182 rotates, which drives the right-angle bracket 183 to move, thereby causing the filter plate 184 to move in position.

[0047] When the filter plate 184 rotates 90°, the filter plate 184 that needs to be replaced or cleaned moves into the sterilization chamber 187. The opening 188 at the partition chamber 185 is replaced by the filter plate 184 at the other end of the right-angle bracket 183, thus achieving the replacement without affecting efficiency. The filter plate 184 that enters the sterilization chamber 187 is sprayed with sterilizing liquid drawn from the sterilization chamber 187 by the micro pump 189, thereby ensuring that there is no cross-infection in the future and achieving the purpose of aseptic sampling.

[0048] Furthermore, the filter plate 184 rotates to the outside of the opening 188, and the empty running suction device 19 can quickly empty the samples inside the equipment to achieve the purpose of cleaning.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
