Food detection sample storage device

Abstract

The invention belongs to the technical field of storage devices, and particularly relates to a food detection sample storage device. The food detection sample storage device comprises a main body shell, wherein the interior of the main body shell is divided into an opening layer, a storage layer and a gas tank layer through a lower partition plate and an upper partition plate, a gas tank layer thermal insulation lining and a low-temperature nitrogen tank are arranged in the gas tank layer, the low-temperature nitrogen tank is connected with an air valve interface and a branch pipe through an air tank interface, the branch pipe is connected with an inner ring pipe and an outer ring pipe, and air pipes are arranged on the inner ring pipe and the outer ring pipe; the storage layer is providedwith a storage layer heat preservation lining, a placement seat is arranged on the lower partition plate, and a storage bottle is arranged in the placement seat; the top of the main body shell is connected with a top cover, the top cover comprises a top cover plate, the bottom surface of the top cover plate is provided with an outer ring plate and an inner ring plate, and the top cover plate is provided with a lower opening; and a rotating shaft is arranged on the top cover, the rotating shaft is connected with an opening cover, the opening cover comprises a fan-shaped cover plate, and an upper opening is formed in the fan-shaped cover plate. The food detection sample storage device is reasonable in structure, convenient to operate, and capable of effectively isolating the inside and outside, stabilizing the moisture of the sample, and avoiding pollution of external air to a sample.

Description

technical field [0001] The invention belongs to the technical field of preservation devices, and in particular relates to a preservation device for food testing samples. Background technique [0002] With the continuous improvement of material living standards, the types of food that people can eat are constantly enriched. In order to ensure food safety and determine the beneficial or harmful ingredients of food, it is necessary to test related foods; before testing related foods, it is first necessary to collect and Prepare food samples. The prepared samples should be analyzed and tested in a short time. If it cannot be carried out immediately, the food samples should be well preserved to prevent contamination. If not properly preserved, it is easy to cause water absorption or loss of water, photolysis of the sample Phenomena such as pyrolysis, fermentation or mildew will change the composition of the sample, which will affect the test results and even lead to wrong conclus...

[0002] With the continuous improvement of material living standards, the types of food that people can eat are constantly enriched. In order to ensure food safety and determine the beneficial or harmful ingredients of food, it is necessary to test related foods; before testing related foods, it is first necessary to collect and Prepare food samples. The prepared samples should be analyzed and tested in a short time. If it cannot be carried out immediately, the food samples should be well preserved to prevent contamination. If not properly preserved, it is easy to cause water absorption or loss of water, photolysis of the sample Phenomena such as pyrolysis, fermentation or mildew will change the composition of the sample, which will affect the test results and even lead to wrong conclusions. After the test, the food samples should be properly preserved for a period of time in case of re-examination when necessary; However, the existing storage device mainly provides refrigeration function, which cannot protect the moisture in the sample, and is easily polluted by external air, and the sealing performance needs to be improved. Therefore, it is necessary to provide a storage device that can maintain the original state of the food sample. of
