GRINDING AND FRICTION GRAIN REFINING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a small-sized and inexpensive grinding and friction grain refining device. SOLUTION: The grinding and friction grain refining device 10 is constituted by engaging the drive shaft of a motor with a first revolving shaft 38 fitted with a grinding and grain refining roll 40 and a second revolving shaft 38 fitted with a friction grain refining roll 56 and rotates the first revolving shaft 38 and the second revolving shaft 22 by making the number of revolutions of the first revolving shaft 38 higher than the number of revolutions of the second revolving shaft 22. The number of revolutions of the grinding and grain refining roll 40 is therefore made higher than the number of revolutions of the friction grain refining roll 56 and the circumferential speed of the grinding and grain refining roll 40 may be made higher than the circumferential speed of the friction grain refining roll 56. Then, there is no need for making the diameter of the grinding and grain refining roll 40 larger than the diameter of the friction grain refining roll 56 and the downsizing of the grinding and friction grain refining device 10 is made possible. Further, one unit of the motor is merely necessitated and therefore the cost of the grinding and friction grain refining device 10 may be made lower.
