Document Type and Number:
Japanese Patent JP2018033788
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To uniformize an amount of discharged beverage materials that are ground, while reducing a production cost.SOLUTION: A raw material grinding device 10 for grinding beverage materials by driving a built-in DC motor 11 and discharging the ground beverage materials, includes: a voltage detection part 14 for detecting a voltage to be applied; and a control part 20 that calculates a drive time of the DC motor 11 on the basis of a voltage value detected via the voltage detection part 14, and a table in which the magnitude of a voltage value to be applied and the length of the drive time of the DC motor 11 are associated such that a total number of revolutions of the DC motor 11 is uniformized, and drives the DC motor 11 until a calculated drive time elapses.SELECTED DRAWING: Figure 1
