Stirring device for food detection

Abstract

The invention discloses a stirring device for food detection. The stirring device comprises a device body; a motor is mounted on the inner wall of the device body, a fixing plate is arranged on the inner wall of the device body, the upper surface of the fixing plate is connected with the lower surface of the motor, a rotating shaft is arranged on the outer wall of the motor, the inner wall of therotating shaft is connected with the outer wall of the motor, and a shaft sleeve is arranged on the outer wall of the rotating shaft. According to the stirring device for food detection, the motor ismatched with the rotating shaft, and under the action of the base, the device body can enable parts on the inner wall to be connected more stably; damage caused by foreign matters invading operation internal parts is avoided; the motor is a servo motor, the stirring speed of the stirring blades is adjusted by adjusting the rotating speed and forward and reverse rotation of the motor, or the stirring blades cannot make contact with a detection liquid when the capacity of the detection liquid in a detection cup is insufficient, so that the defect that stirring blades of a traditional stirring device for food detection are incomplete in stirring is overcome, the inspection cost is saved, and the stirring device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of food testing, in particular to a stirring 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. In food testing, it is often necessary to stir certain liquid samples. The existing stirring The way is to manually stir the samples in the beaker with a stirring rod, which not only has low stirring efficiency but also increases the work intensity of the testing personnel. In the prior art, for example, the invention patent with the application number 201621354212. , a runner, a mounting rod, a stirring rod and a fixing clip, the upper part of the base is provided with an inverted "L"-shaped frame, and the upper part of the frame is fixedly installed with a motor whose output shaft is set straight down. A runner is ...

[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. In food testing, it is often necessary to stir certain liquid samples. The existing stirring The way is to manually stir the samples in the beaker with a stirring rod, which not only has low stirring efficiency but also increases the work intensity of the testing personnel. In the prior art, for example, the invention patent with the application number 201621354212. , a runner, a mounting rod, a stirring rod and a fixing clip, the upper part of the base is provided with an inverted "L"-shaped frame, and the upper part of the frame is fixedly installed with a motor whose output shaft is set straight down. A runner is fixedly installed on the output shaft of the motor, and a horizontal installation rod is fixedly installed on the left side of the frame. The upper end of the frame is rotationally connected with the edge of the bottom of the runner, and the left side of the frame is fixedly installed with a fixing clip for fixing the beaker directly below the stirring rod. Although the structure of the invention is simple, there are many deficiencies and defects. , in the existing equipment, there are defects in the design of the installation rod, the height of the installation rod cannot be adjusted, the stirring part of the stirring rod is completely and the height of the fixing clip cannot be adjusted, in view of these situations, in order to avoid the above technical problems, it is necessary to provide a Stirring device for food testing to overcome the defects in the prior art
