Test tube drying device for food detection

Abstract

The invention discloses a test tube drying device for food detection, and relates to the technical field of food safety, the test tube drying device comprises a workbench, a drying unit and a supporting unit; a supporting unit is installed in the middle of the upper end of the workbench. Each drying unit comprises an exhaust pipe, an air inlet pipe, a fastening ring, a filter screen, a metal rod, a heating wire and an air inlet fan, three circular holes in a linear array are formed in the front side of the upper end of the workbench, the exhaust pipes are arranged on the inner walls of the circular holes, the lower ends of the three exhaust pipes are connected with one side of a ventilation pipe, and the air inlet pipe is arranged at the front end of the ventilation pipe; a fastening ring is arranged on the outer side of the front end of the air inlet pipe, a filter screen is arranged on the inner wall of the fastening ring, three metal rods distributed in an array mode are arranged in the middle of the inner wall of the air inlet pipe, the water control effect of the whole structure on a test tube is good, residual water stains can be reduced, the drying time can be shortened, the fixing structure of the test tube is stable, and the test tube can be dried conveniently. And deviation is not easy to generate in the drying process.

Description

technical field [0001] The invention relates to the technical field of food safety, in particular to a test tube drying device for food testing. Background technique [0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly for the detection of some harmful and toxic indicators, such as heavy metals, aflatoxin, etc. Test tubes are often used in food testing, and test tubes are divided into ordinary test tubes and support test tubes , centrifuge test tubes, etc. The test tube is an indispensable experimental tool in the experiment. [0003] The patent disclosed in the prior art with the publication number CN206626905U includes a box body, a hot air blower, an air box, an air guide pipe, an air hole, an air outlet, a condensation pipe and a waste liquid box, and the inside bottom of the box is provided with a hot air blower. , the upper part of the hot air blower communicates with an air box, and the upper part of the air bo...

Problems solved by technology

[0004] Its structure as a whole does not have a good water control effect on the test tube, and it is easy to cause too much residual water stains and increase the drying time, and the fixed structure of the test tube is not stable enough, and it is easy to produce deviation during the drying process. Therefore, we propose A test tube drying device for food testing
