A test tube cleaning and drying device for food testing

Abstract

The invention discloses a cleaning and drying device for test tubes for food detection. The cleaning and drying device comprises a base plate and a cleaning tank body. The cleaning tank body is internally provided with an upper fixing plate and a lower fixing plate. The side edge of the upper fixing plate is connected with the inner wall of the cleaning tank body in a vertically-sliding manner. The lower fixing plate is rotatably connected with the upper fixing plate. A cleaning brush is arranged on the side wall of the upper end of each rotary casing pipe. A transmission gear is arranged on the side wall of the lower end of each rotary casing pipe, wherein the transmission gears are engaged with one another. A driving vertical shaft is arranged in the center of the lower end face of a fixing transverse plate, wherein the driving vertical shaft penetrates the bottom wall of the cleaning tank body. The driving vertical shaft is connected with a cleaning motor arranged on support pillarsthrough a transmission mechanism. The top end of the driving vertical shaft is rotatably connected with the fixing transverse plate and provided with a driving gear, wherein the driving gear is engaged with the transmission gears located at the outer side. The cleaning and drying device is simple in structure; the multiple test tubes can be cleaned at the same time; and the cleaning and drying device is high in cleaning efficiency, convenient to operate and mount, good in drying effect and high in practicability.

Description

technical field [0001] The invention relates to food testing equipment, in particular to a test tube cleaning and 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, aflatoxins, etc. Test tubes are often used in food testing, and test tubes are divided into ordinary test tubes, [0003] There are many kinds of test tubes, centrifuge test tubes, etc. Test tubes are indispensable experimental equipment in experiments. At present, in the drying work of test tubes, it is necessary to clean and dry test tubes for next use, and most of them are still using cleaning. After completion, use natural air drying or manual wiping, the former drying speed is too slow, the latter is time-consuming and laborious, and the drying treatment of test tubes or flasks is not ideal, which indirectly affects the e...
