Description

Technical Field

[0001] This utility model belongs to the field of food sealing technology, and in particular relates to a sample sealing device for food testing. Background Technology

[0002] When food samples are taken and sealed, a sterile environment must be maintained. Typically, the sample is placed in a container, and the air inside is evacuated to create a vacuum environment. This prevents residual air from contacting the food sample and causing spoilage. However, vacuuming each sample container individually is inefficient. Furthermore, when the sample container is vacuumed, the sample is at room temperature. During the vacuuming process, microorganisms in the food sample can remain highly active and multiply. As a result, the number of microorganisms inside the food sample before sealing is higher than before vacuuming, leading to inaccurate subsequent testing.

[0003] To address these issues, we provide a sample sealing device for food testing. Utility Model Content

[0004] The purpose of this invention is to provide a sample sealing device for food testing. By installing a horizontal plate and a vertical plate inside a refrigerator, food samples are placed into a sample storage component, which is then placed in a compartment separated by the horizontal and vertical plates. This keeps the food sample in a low-temperature environment, inhibiting the activity of microorganisms in the food sample. An air extraction component is installed at the bottom of the refrigerator. The air pump in the air extraction component is connected to an air extraction pipe, which extends into the refrigerator. After placing the sample storage component in the compartment of the refrigerator and connecting it to the air extraction pipe, the air pump extracts air from the sample storage component. This achieves air extraction from the sample storage component in a low-temperature environment, preventing the proliferation of microorganisms in the food sample during vacuum extraction, thus avoiding a higher number of microorganisms in the sample than before vacuum extraction.

The two air extraction pipes pass through the bottom of the refrigerator and the horizontal plate on both sides of the vertical plate, and the air extraction pipes are respectively connected to the sample storage components on both sides.

[0007] A further feature of this invention is that the sample storage component includes a placement chamber, a top cover, and a sample retention component. The placement chamber is fitted into the compartment of the refrigerator, the top cover covers the upper opening of the placement chamber, the sample retention component is placed inside the placement chamber, and an exhaust duct is provided at one end of the top cover away from the opening of the refrigerator.

[0008] A further feature of this invention is that the side of the extraction pipe is connected to an extraction branch pipe, which is sleeved inside the extraction channel.

[0009] A further feature of this invention is that the sample retention component includes a sample retention box and a lid. The sample retention box is placed inside the placement chamber, and the lid covers the upper part of the sample retention box. The lid is connected to the air extraction channel.

This achieves air extraction from the sample storage component 2 in a low-temperature environment, preventing the proliferation of microorganisms in the food sample during the vacuum extraction process, which would result in a higher number of microorganisms in the sample than before vacuum extraction.

[0027] Specifically, the refrigerator 1 has openings at both ends. A horizontal plate 101 is fixedly installed inside the refrigerator 1, and a vertical plate 102 is fixedly installed inside the refrigerator 1.

[0029] Furthermore, the side of the extraction pipe 301a is connected to an extraction branch pipe 301a-1, which is sleeved inside the extraction channel 202a. The food sample is loaded into the sample retention component 203, and the sample retention component 203 is placed in the placement chamber 201. The top cover 202 is placed on the top of the placement chamber 201, so that the extraction channel 202a on the top cover 202 is connected to the sample retention component 203. The placement chamber 201 is placed in the refrigerator 1, so that the extraction channel 202a is connected to the extraction branch pipe 301a-1, thereby extracting the air from the sample retention component 203 by the extraction pump 301.

[0030] The operation process in this embodiment is as follows:

[0031] Food samples are placed into the sample retention component 203, and the sample retention component 203 is placed into the placement chamber 201. The top cover 202 is placed on the top of the placement chamber 201, so that the air extraction channel 202a on the top cover 202 is connected to the sample retention component 203. The placement chamber 201 is placed into the refrigerator 1, so that the air extraction channel 202a is connected to the air extraction branch pipe 301a-1, thereby extracting the air from the sample retention component 203 by the air extraction pump 301.

[0032] Example 2

[0033] Please see Figures 1 to 5Based on Example 1, the sample retention assembly 203 includes a sample retention box 203a and a box cover 203b. By placing a food sample into the sample retention box 203a, covering the top of the sample retention box 203a with the box cover 203b, and placing the sample retention box 203a into the placement chamber 201, the air extraction channel 202a on the top cover 202 of the chamber is connected to the box cover 203b, thereby allowing the air extraction pump 301 to extract the air from the sample retention box 203a.

[0034] Specifically, the sample retention box 203a is placed inside the placement chamber 201, and the box cover 203b is placed on the upper end of the sample retention box 203a. The box cover 203b is connected to the air extraction channel 202a.

[0035] Furthermore, a top pipe 202b is vertically fixed at the lower end of the top cover 202. The top pipe 202b is connected to the air extraction channel 202a.

After the sealing cap 203b-5 is pressed downward by the top tube 203b-2, the air pump 301 works to extract the air in the sample box 203a from the air outlet pipe on the box cap 203b and draw it into the air extraction channel 202a from the side wall hole 202b-1 at the lower end of the top tube 202b.

[0038] The operation process in this embodiment is as follows:

[0039] When food samples are placed into sample retention box 203a, the box lid 203b is placed on top of sample retention box 203a. At this time, the sealing cap 203b-5 is pressed against the lower end of the top tube hole 203b-2 by the compression spring 203b-4 to prevent external air from entering.
