Description

Technical Field

[0001] This utility model belongs to the field of food testing technology, specifically, it relates to a culture device for food testing. Background Technology

[0002] Food safety is of paramount importance. Before food is produced, its spoilage period needs to be tested. Generally, petri dishes are used to test for microorganisms in the food. The lid of the dish is placed on the dish to prevent the culture medium from being contaminated by microorganisms in the external environment. Since culture medium needs to be added to the food during testing, the ratio between the culture medium and the food varies. Therefore, different ratios will yield different results. Conventional petri dish testing methods are relatively simple and not representative enough, which will affect the final test results.

[0003] Utility model patent CN217895598U discloses a food testing petri dish, including a bottom and a lid. The surface of the lid is fixedly equipped with anti-slip protrusions, which are distributed at equal angles about the axis of the lid. A display box is fixedly installed on the outer surface of the bottom, which is also distributed at equal angles about the axis of the bottom. A connecting groove is formed on the surface of the display box. Baffles are rotatably connected to both sides of the display box, and the baffles are symmetrically distributed about the center line of the display box.

[0004] As shown in the above utility model, existing food testing petri dishes generally use baffles to prevent the information display board inside the display box from falling off when the whole dish is turned over. The annular groove is connected to the sealing ring to prevent the culture medium from being affected by external microorganisms. The limiting groove and the limiting block are connected to ensure that the first and second separators can be accurately connected, thereby improving the separation effect of the petri dish. However, this method only sets multiple partitions in the dish to separate the culture medium. This method is inconvenient to remove the culture medium for testing. During testing, the culture medium will come into contact with the external environment, affecting the test results. In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 4 As shown, a food testing culture device includes a housing 1, a cover plate 2, a culture component 3, and a culture medium 4.

[0028] Specifically, the interior of the box 1 has multiple placement slots 14 arranged in a ring array for placing culture medium 4. The periphery of the box 1 has multiple slots 11 arranged in a ring array. A first sealing ring 12 is bonded to the edge of the upper surface of the box 1. A heater 13 is installed in the middle of the inner bottom wall of the box 1. The heater 13 can heat the inside of the box 1 so that the temperature inside the box 1 can meet the requirements for the culture medium 4.

[0029] Specifically, the cover plate 2 is set on the top of the box 1 to seal the box 1 and prevent the exchange of air between the inside and outside. The edge of the cover plate 2 is fixed with a sealing plate 21 with an annular structure. A second sealing ring 22 is bonded to the lower surface edge of the sealing plate 21. The second sealing ring 22 corresponds to the first sealing ring 12. The first sealing ring 12 and the second sealing ring 22 squeeze and cooperate with each other to achieve the sealing effect.

[0030] More specifically, the culture component 3 is mounted on the cover plate 2 and is used to assist in the culture medium 4 inside the chamber 1. The culture component 3 includes a geared motor 31 fixed in the middle of the upper surface of the cover plate 2. The output shaft of the geared motor 31 is fixed with a movable plate 32, which is located in the middle of the lower surface of the cover plate 2. A supplementary light 33 is installed at one end of the lower surface of the movable plate 32, and an ultraviolet lamp 34 is installed at the other end of the lower surface of the movable plate 32. The geared motor 31 drives the supplementary light 33 and the ultraviolet lamp 34 to rotate through the movable plate 32. The ultraviolet lamp 34 can sterilize the environment inside the chamber 1 before incubation, and the supplementary light 33 can provide supplementary lighting for different culture media 4 during the incubation process, thereby improving the incubation efficiency of this device.

[0031] More specifically, the culture medium 4 is magnetically connected to the placement slot 14 inside the box 1 for culturing microorganisms for food testing. The culture medium 4 includes a box 41, with an annular groove 42 on the top edge of the box 41. Multiple matching slots 43 arranged in a ring array are provided at the opening of the annular groove 42. A sealing cover 44 is provided on the top of the box 41. Multiple limiting plates 45 that are adapted to the matching slots 43 are fixed around the periphery of the sealing cover 44. A transparent glass plate 46 is embedded in the middle of the sealing cover 44. The sealing cover 44 can be sealed and limited on the box 41 by the limiting plates 45, the annular groove 42 and the matching slots 43 on the box 41, preventing the environment inside the box 41 from contacting the external environment. The transparent sealing plate 21 facilitates the observation of the culture medium 4 by the staff and also facilitates the supplemental lighting of the culture medium 4.

[0032] Before incubation, the cover plate 2 is closed, and the ultraviolet lamp 34 is rotated by the geared motor 31 to sterilize the environment inside the chamber 1. Then, the cover plate 2 is opened, and the culture medium 4 is placed in the corresponding placement slot 14. The cover plate 2 is then closed until the elastic clip 23 on the cover plate 2 engages with the slot 11 on the chamber 1, ensuring a tight seal between the first sealing ring 12 and the second sealing ring 22. The heater 13 is then activated to heat the environment inside the chamber 1 to meet the cultivation requirements of the microorganisms in the culture medium 4. Finally, the geared motor 31 drives the supplemental light 33 to rotate, further sterilizing the environment inside the chamber. Different culture media 4 are supplemented with light (this step can be omitted if supplemented light is not required). After the culture is completed, the cover plate 2 is opened, the corresponding culture medium 4 is taken out, and the culture medium 4 is taken to the testing institution for testing. During this process, the environment inside the culture medium 4 does not come into contact with the external environment and will not be affected by the external environment, which improves the culture accuracy of this device. During testing, the sealing cover 44 is rotated until the limiting plate 45 on the sealing plate 21 rotates to the mating groove 43, and then it is moved upward to move the limiting plate 45 out of the mating groove 43. At this time, the sealing cover 44 can be separated from the box body 41, and the food inside the box body 41 can be tested at the same time.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
