Description

Technical Field

[0001] The utility model relates to the technical field of sterilization, and more specifically to a food microorganism detection and sterilization device. Background Art

[0002] Nowadays, with the improvement of people's lives, the requirements for food safety are becoming more and more stringent. In the process of food production, it is often necessary to use detection devices to detect various microorganisms contained in food. Now most of the food is placed directly on the tray, but if the tray is not sterilized before use, it may cause the microorganisms in the tray to react with the samples of the food to be tested. The existing trays need to be cleaned after use and then placed in the sterilization equipment. There are many water droplets on the surface of the cleaned tray. When placed on the bracket in the sterilization box, the water droplets on the surface of the upper tray will fall onto the tray below it, causing the water droplets to flow in different detection tools, and the water droplets on the surface of the tray accumulate in the equipment and cannot be discharged. If they are not cleaned for a long time, it is easy to breed bacteria, thereby affecting the sterilization effect and causing the test results to be affected.

[0003] A Chinese patent discloses a sterilization device for pet food microbial detection. The patent authorization number is CN217297851U. The cleaned detection tools are placed on a carrier plate. At this time, water droplets on the outer surface of the detection tools fall into the receiving box below the carrier plate through the holes on the carrier plate when they fall. During the sterilization process, the water droplets on the outer surface of the detection tools will not directly drip onto the carrier plate at the lower end, reducing the flow of water droplets between different detection tools and the stay of water droplets in the sterilization equipment, making it convenient to use.

[0004] However, in the patent authorization number CN 217297851 U, the detection tools that need to be sterilized after cleaning are placed on the upper surface of the carrier plate, and then the fixing block is pushed to move the carrier plate to the inside of the main body. Since the detection tools and the carrier plate are sterilized at high temperature, when the staff retrieves the detection tools, their arms need to be extended into the inside of the chassis, which poses a risk of burns. Therefore, we propose a food microorganism detection and sterilization device to solve the above-mentioned problems. Utility Model Content

[0032] A sterilization chamber 2 is provided inside the sterilization box 1, an electric heating coil 3 is installed at the bottom of the sterilization chamber 2, a groove 4 is provided at the top of the sterilization chamber 2, and guide holes 5 are symmetrically provided at the edge of the groove 4;

[0033] A servo motor 6 is installed at the bottom of the sterilization box 1, and the power output end of the servo motor 6 is transmission-connected to a driving shaft 7 extending to the inside of the sterilization chamber 2, and a threaded portion 8 is provided on the outer wall of the driving shaft 7;

[0034] A cover 21 is embedded in the inner side of the groove 4, and an internal thread sleeve 10 threadedly connected to the threaded portion 8 is welded to the middle of the lower surface of the cover 21. A tray 11 is installed on the outer wall of the bottom end of the internal thread sleeve 10, and the surface of the tray 11 is provided with through holes in an array. The edge of the cover 21 is symmetrically integrally formed with a flange, and a guide column 12 is welded on the lower surface of the flange to match the guide hole 5.

[0035] It should be noted that the servo motor 6 is set with a suitable forward and reverse rotation program. First, an appropriate amount of water is injected into the disinfection chamber 2 set on the inner side of the sterilization box 1, and the food microorganism detection tools that need to be sterilized after cleaning are placed on the upper surface of the tray 11. Then, the power output end of the servo motor 6 drives the drive shaft 7 to rotate counterclockwise, and the threaded portion 8 set on the outer wall of the drive shaft 7 cooperates with the internal threaded sleeve 10 to screw in, so that the guide column 12 cooperates with the guide hole 5 to move downward, and then the cover 21 blocks the top of the disinfection chamber 2, and the tray 11 is located above the liquid surface. The electric heating coil 3 is energized to work until the water in the disinfection chamber 2 is heated to boiling, and sterilization is carried out using high temperature and high pressure. After the disinfection is completed, the drive shaft 7 is driven by the power output end of the servo motor 6 to rotate clockwise, so that the internal threaded sleeve 10 drives the cover 21 to move upward until the sterilized food microorganism detection tools placed on the tray 11 are located above the disinfection chamber 2, which can effectively prevent the staff from being scalded during the taking process.

[0036] like Figure 2 As shown, a sealed bearing 9 is installed at the junction of the bottom of the sterilization box 1 and the driving shaft 7;

[0037] It should be noted that the interference fit between the sealing bearing 9 and the root of the driving shaft 7 can effectively prevent water leakage inside the disinfection chamber 2.

A pressure gauge 15 and a pressure relief valve 16 are respectively installed on the upper surface of the cover 21;

[0039] It should be noted that after the cover 21 is embedded into the inner side of the groove 4, the top opening of the disinfection chamber 2 is blocked. At the same time, the sealing rubber ring 14 arranged on the outer wall of the boss 13 is abutted against the inner wall of the disinfection chamber 2 to fill the gap at the junction of the cover 21 and the disinfection chamber 2, so that the disinfection chamber 2 is completely in a sealed state, which is conducive to high-temperature and high-pressure disinfection work. At the same time, the pressure gauge 15 is used to detect the pressure inside the disinfection chamber 2.

[0041] It should be noted that, during the process of adding and discharging liquid through the liquid adding pipe 19 and the liquid discharging pipe 20 , the liquid level can be conveniently observed through the liquid level window 17 .

[0042] like Figure 1 , Figure 2 , Figure 4 As shown, a control host 18 fixedly connected to the outer wall of the sterilization box 1 is provided on one side of the liquid level window 17, and the output end of the control host 18 is electrically connected to the output end of the electric heating coil 3 and the servo motor 6;

[0043] It should be noted that a set of appropriate forward and reverse rotation programs is set for the servo motor 6 by controlling the host computer 18 , and the working states of the electric heating coil 3 and the servo motor 6 can be controlled by controlling the host computer 18 .

[0044] During use: the servo motor 6 is set with a set of appropriate forward and reverse programs. First, an appropriate amount of water is injected into the disinfection chamber 2 set on the inner side of the sterilization box 1, and the food microorganism detection tools that need to be sterilized after cleaning are placed on the upper surface of the tray 11. Then, the power output end of the servo motor 6 drives the drive shaft 7 to rotate counterclockwise, and the threaded portion 8 set on the outer wall of the drive shaft 7 cooperates with the internal threaded sleeve 10 to screw in, so that the guide column 12 cooperates with the guide hole 5 to move downward, and then the cover 21 blocks the top of the disinfection chamber 2, and the tray 11 is located above the liquid surface. The electric heating coil 3 is energized to work until the water in the disinfection chamber 2 is heated to boiling, and sterilization is carried out using high temperature and high pressure. After the disinfection is completed, the drive shaft 7 is driven by the power output end of the servo motor 6 to rotate clockwise, so that the internal threaded sleeve 10 drives the cover 21 to move upward until the sterilized food microorganism detection tools placed on the tray 11 are located above the disinfection chamber 2.
