Food detection sampling device

Abstract

The invention discloses a food detection sampling device, and relates to the technical field of food detection. The food detection sampling device comprises a rack, a sample collection box and a sampling mechanism, the upper end of the rack is provided with a surrounding light source, the upper end of the rack is provided with an electric cylinder, and the output end of the electric cylinder is connected with a lifting frame. The sampling mechanism is arranged on the lifting frame, particle gaps of solid food or bubbles accumulated and hung when non-solid food enters the samplers can be effectively eliminated through rapid vibration formed by the two samplers, and the sampling accuracy is guaranteed; and under the action that the middle parts of two guide rails are wide and the two ends of the two guide rails are narrow, the sliding paths of two samplers at the same depth are not linear, so that food at the same depth position in the sample collection box cannot flow and cover on the moving track lines of the samplers, the edge and middle part of the same depth position can be sampled, and the authenticity of a detection result is improved.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a food detection and sampling device. Background technique [0002] Food testing mainly includes quality testing and safety testing, that is, testing the physical and chemical indicators of the ingredients in the food, and testing whether it contains toxic substances and their content indicators. The testing process is usually carried out in the laboratory, and there are various types of food to be tested. Such as solid granular food, solid-liquid coexistence food, and semi-solid gel food, etc., the existing technology needs to be equipped with multiple sets of sampling devices that match the corresponding types of food. [0003] However, during the long-term use of the existing sampling device, it is found that there are still certain disadvantages: 1. For solid granular food, there are gaps between the food in the sampling space, resulting in differences in the amount of...

[0003] However, during the long-term use of the existing sampling device, it is found that there are still certain disadvantages: 1. For solid granular food, there are gaps between the food in the sampling space, resulting in differences in the amount of each sampling, rather than solid state. When the food enters the sampler, because the internal air cannot be emptied in time, air bubbles often accumulate on the inner wall of the sampler after the sample is filled, which also leads to differences in the sampling volume of each time; Horizontal multi-point sampling at the same height has the situation of sample flow coverage, that is, the sample at the next sampling point is greatly affected by the sample at the previous sampling point with the movement of the sampling device, and for the food container , especially for light-transmitting utensils such as glass, the physical and chemical indicators of the food on the edge of the utensil are more affected by external environmental factors than those in the middle of the utensil. Inspection of food will affect the authenticity of the test results
