The spring is fixed at the bottom of the containing groove and fixedly connected with the side wall of the test paper bottle; the detection unit comprises a light blocking shield and reagent grooves, the reagent grooves are formed in a fixed base, a containing cell is formed in the fixed base, the light blocking shield is rotationally connected with the containing cell, a torsional spring is installed on a rotating shaft, and an illuminating lamp is arranged in the light blocking shield. The indication unit comprises a transmission shaft, a large roller and a small roller, a groove for containing the indication unit is further formed in the fixed base, the large roller and the small roller can rotate in the corresponding groove, the color card is arranged on the large roller in a surrounding mode, and the transmission shaft is fixedly connected to the large roller and the small roller. The food detection device further includes a limiting device used for limiting the test paper bottle and the light blocking shield.

Description

technical field [0001] The invention relates to the field of food detection, in particular to a device for detecting food safety. Background technique [0002] Food inspection technology is an indispensable technology for the good development of modern society. According to the "Food Sanitation Law of the People's Republic of China", the inspection of food quality includes the inspection of food outer packaging, inner packaging, labeling, physical and chemical indicators and other health indicators. inspection. [0003] Food testing in a narrow sense mainly refers to food safety testing, using physical and chemical indicators as a reference. Mainly by detecting whether the content of harmful substances in food exceeds the standard, such as edible oil acid value, peroxide value, sulfur dioxide (bird's nest wolfberry), aflatoxin (tea), Escherichia coli, etc. Usually the simplest and fastest detection method is to use detection test paper and auxiliary detection liquid.

Problems solved by technology

[0004] For different test items, the formula of the test solution is different, and the test paper may also be different. Therefore, each test needs to use the matching test paper and test solution. Once the test items and tested objects increase, it is easy to cause confusion. Because the test paper itself does not indicate which test it is used for, and the color and shape of the test paper for most test items are very close, which may lead to operational errors.

Due to the relatively wide range of operations and a lot of repetitive work, it is generally difficult to achieve single-person testing and recording

[0005] Moreover, when testing outdoors, due to the sun's rays, when the color difference between the color on the test paper and the test paper itself is small, it is difficult for the staff to distinguish the color difference on the color card, or to distinguish the color difference.

Generally, the test paper is packed in a bottle, and the color card is marked on the packaging paper of the bottle body. The color of the bottle body is difficult to distinguish under the light, and the color card is also easy to fade during long-term use.
