Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a food detection experimental table which is convenient for repeated use of test tubes. Background Art

[0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly some harmful and toxic indicators, such as heavy metals, aflatoxin, etc. An important aspect of food science and engineering is to introduce and apply chemical unit operations and develop food engineering unit operations, thereby promoting the development of the food industry towards large-scale, continuous and automated production.

[0003] Through searching, it is found that the Chinese patent publication number CN216013327U discloses "a test bench for food quality testing", which proposes that the existing food testing bench requires the experimenter to clean the test tube by himself, so that it is easy to contact various reagents and reagent solvents, which will hurt the skin of the experimenter, and the test tubes need to be cleaned one by one, and the cleaning efficiency is low. The patent starts the motor one, and under the transmission action of the synchronous wheel and the synchronous belt, the movable plate drives the frame to move horizontally to the top of the pool, starts the motor four, inverts the test tube, pours the solid-liquid mixture into the pool, separates the solid and liquid through the filter screen, the solid enters the waste box through the inclined tube, and the liquid enters the waste liquid barrel with the corresponding diversion pipe, starts the motor two, and the horizontal plate drives the brush tube to descend into the test tube, starts the water pump, and the water flows into the corresponding water supply pipe to spray water on the test tube through the nozzle, and starts the motor three. Under the transmission action of the mutual meshing of the sprocket and the chain, multiple brush tubes rotate at the same time to clean the test tube, which can reduce the contact between the experimenter and the chemical reagent, and the cleaning efficiency is high.

[0004] However, in repeated experiments, multiple test tubes are needed to hold samples. Taking out the test tubes at one time is prone to contamination, and they can only be taken out multiple times. Constantly taking out the test tubes from the laboratory cabinet is prone to fatigue. Therefore, the above-mentioned test bench has the problem that it is cumbersome to take out the test tubes multiple times, which is inconvenient for repeated experiments. Utility Model Content
