Embodiment

[0037] Example: such as figure 1 As shown, the present invention provides a kind of technical scheme, a kind of convenient food detection method, comprises the following steps:

[0038] S1. Put the food to be detected into the mixing cylinder 5 on the rotating frame 4, and add the extracting liquid to the inside of the mixing cylinder 5 at the same time;

[0039] S2. Stir the extract and the food sample by driving and hammering the mechanism 6, so that the food is fully dissolved in the extract;

[0040] S3. Discharging the stirred solution into the inside of the filter cartridge 1 through the stop-rotating discharge mechanism 7 for storage;

[0041] S4. Send the solution sample into the inside of the measuring cup through the dripping and homogenizing mechanism 8, and mix the solution sample with the color developer, and then perform a color comparison to detect whether the heavy metal content in the food exceeds the standard.

[0042] According to the above technical schem...

Abstract

The invention discloses a portable food detection method, which comprises the following steps: S1, putting food to be detected into a mixing barrel on a rotating frame, and adding an extracting solution into the mixing barrel at the same time; s2, stirring the extracting solution and the food sample through a driving and mallet pounding mechanism, so that the food is fully dissolved in the extracting solution; and s3, discharging the stirred solution into a filter cartridge through a stalling discharging mechanism for storage. The portable food detection method is scientific and reasonable in structure and safe and convenient to use, the driving and mallet pounding mechanism is arranged, a driving motor and a guide wheel are matched to drive the mixing barrel to rotate, an extracting solution and food in the mixing barrel are rotationally stirred, the mixing effect is improved, the food is conveniently dissolved in the extracting solution, sampling is convenient, meanwhile, through the cooperation of a driving gear and a driven gear, in the rotating process of the mixing barrel, a screw rod is driven to rotate, a reciprocating plate ascends along the screw rod to be attached to a top plate, a travel switch is started, and a driving motor rotates reversely.

Description

technical field [0001] The invention relates to the technical field of equipment, in particular to a convenient food detection method. Background technique [0002] After the sample is digested, all forms of heavy metals, including arsenic, lead, cadmium, chromium, mercury, nickel, iron, aluminum, zinc, manganese, copper, etc., are converted into ionic forms, and the color is developed after adding relevant detection reagents. The color depth of the solution within a certain concentration range is proportional to the content of heavy metals, obeying the Lambert-Beer law, and then measuring the content value through the instrument, which is in line with the national standard for the safety and quality of agricultural products and the safety requirements of pollution-free vegetables. comparison, to determine the heavy metal content of vegetable samples; [0003] However, the efficiency of dissolution and extraction of existing samples is poor, which affects the efficiency of ...
