Description

Technical Field

[0001] The utility model relates to the technical field of food inspection, in particular to a food nutrition quick inspection device. Background Art

[0002] Food nutrition rapid testing is to test the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products to ensure that the nutritional quality of the products is qualified. Before the food nutrition test, it is necessary to take samples, and the number of samples should reflect the nutritional quality of the food and meet the sample quantity requirements of the test items.

[0003] In the prior art, there is a Chinese patent for a food rapid inspection sampling device disclosed in the publication number CN217111650U, in which a rotating rod is fixedly provided on a support rod on one side of the top of the base through a first motor, a rotating seat is fixedly provided on the top of the rotating rod, a mounting plate is fixedly provided on one side of the bottom of the rotating seat through a hydraulic rod, a sampling syringe is fixedly provided on the bottom of the mounting plate, a piston is fixedly provided on the top of the sampling syringe through an electric telescopic rod, a turntable is rotatably connected to one side of the top of the base, a sampling box is movably provided on the turntable, a fixed rod is provided at the bottom of the sampling box, a hollow column is movably provided on the top of the fixed rod, a test tube rack is fixedly provided on the surface of the hollow column, a sampling test tube is clamped on the test tube rack, and a refrigeration device is provided at the bottom of the sampling box. The new type can adjust the direction and height of the sampling syringe, so that the sampling syringe can automatically sample liquid food, inject the sample in the sampling syringe into different sampling test tubes, realize the collection of multiple samples, improve the sample collection efficiency, and ensure the accuracy of the test results.

[0004] However, the above patent has some shortcomings. In actual use, when collecting multiple samples, the patent drives the first gear and then drives the second gear to rotate to realize the rotation of the turntable. However, when injecting the sample in the sampling syringe into different sampling tubes, the second motor needs to be started and stopped continuously to ensure the accuracy of injecting the sample into multiple sampling tubes. When the motor is started and stopped continuously, it will affect the temperature of the motor. The motor will generate heat when starting and running. If it is started and stopped frequently, it will cause the temperature of the motor to be unstable, and it is easy to cause thermal decay and thermal fatigue problems in the motor, thereby affecting the life and performance stability of the motor, thereby affecting the service life of the entire device. Therefore, a food nutrition rapid testing device is proposed to solve the above problems. Utility Model Content
