Abstract

The invention relates to the technical field of food detection, and discloses a reagent dropping device for color-coloring experiments in food detection, which includes a burette and a drip head, the upper end of the burette is open, and the burette is transparent, and the side wall of the burette is provided with The dripper is located under the burette and is fixedly connected with the burette. The upper end of the burette is provided with a large extruder and a small extruder. There is a limiting plate under the small extruder. The reagent dropping device used in the color test in food testing, the user only needs to turn the rotating disk or ring to squeeze out the reagent when using it. At the same time, because the device The structural design, the user can use the rotating disk or the rotating ring to squeeze out more or less reagent according to the needs, so that the user can add the reagent more freely and accurately when performing the test, increasing the device practicality.

Description

technical field [0001] The invention relates to the technical field of food testing, in particular to a reagent dropping device for color-coloring experiments in food testing. Background technique [0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly the detection of some harmful and toxic indicators, such as heavy metals, aflatoxins, etc. An important aspect of food science and engineering is the introduction and application of chemical unit operations, and the development of food engineering unit operations, thereby promoting the development of the food industry in the direction of large-scale, continuous and automated. Reagent drops for coloring experiments in food testing The adding device is a reagent dropping device for food testing and testing. The existing reagent dropping device has a relatively simple structure. Control the piston rod so as to control the amount of dripping reagents. It is impossible to achie...
