Automatic food kinematic viscosity measurement device and measurement method

The invention relates to an automatic food kinematic viscosity measurement device and measurement method. The technical scheme includes that the device comprises a first camera, a second camera, a controller, a positive pressure generator and a negative pressure generator. A lens of the first camera is horizontally aligned to an upper scale mark, a lens of the second camera is horizontally alignedto a lower scale mark, a first electromagnetic valve used for sealing and conducting of an upper opening portion of a thick tube is arranged at the upper end of the thick tube, the positive pressuregenerator is connected with a pressure access tube through a second electromagnetic valve, the negative pressure generator is connected with the pressure access tube through a third electromagnetic valve, and accordingly a positive and negative pressure supply structure of a capillary viscometer is formed. The first camera, the second camera, the first electromagnetic valve, the second electromagnetic valve and the third e
