It is also widely used in chemical industry, textile, medicine, feed, paper making, petroleum and other industries, and requirements for its star ch content also is higher and higher . Design of potato starch instrument is imminent, in the design of the potato starch content of instrument, powered by two stepper motors, ensure the position accuracy of the rotation, motor connected to the rotating device is directly by gear motor 1 through th e gear motor to control the rotation of the rotating mechanism, again through the rotating device on the hook for slide block to the measuring device. Motor with rotating device is also The motor 2 gear meshing directly, through the rotating device of the hook sample was obtained from the measurement device, again through the inverse rotation remove sample, plete the power transfer process. Potato starch content determination, the traditional potato s tarch content determination of labor intensity, low efficiency, human error is big, at present our country of the potato starch content of automation machinery monitoring level is relatively backward. This design in order to solve this problem, design the light potato powder content automatic tester, automate the potato starch content determination, and improves the measurement efficiency.
