Technical Field

[0001] The utility model relates to the technical field of food sampling equipment, in particular to a sampling device for food safety inspection. Background Art

[0002] Food testing is based on some basic theories and various technologies of physics, chemistry and biochemistry, and in accordance with established technical standards, such as international and national food hygiene / safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products to ensure the quality of the products. Food inspection includes sensory testing of food, testing of nutrients, additives and harmful substances in food, etc. During the testing process, sampling devices are required to take samples for subsequent testing.

[0003] However, there are still some problems in the use of existing food detection sampling devices. For example, some foods are liquid and some foods are solid. The existing sampling devices can only sample liquid or solid foods individually, which is very inconvenient to use. Moreover, the samples are easy to fall off after being taken out and before being placed in the storage box, resulting in the loss of the sampled samples.

[0004] To this end, the utility model provides a sampling device for food safety inspection, which solves the above-mentioned problem by arranging structures such as a liquid sampling tube, a solid sampling tube, and a blocking block. Utility Model Content
