    • PROBLEM TO BE SOLVED: To provide a powder supply device and a powder supply method which can precisely control an amount of powder to be supplied in a short time.SOLUTION: A powder supply device 1 includes: a powder valve 21 connected to a powder conveying pipe 31; an internal pressure control valve 22 which is connected to a feed tank 11 and controls a pressure in the feed tank 11; and a carrier gas main pipe 33 which is connected to the powder conveying pipe 31 and introduces carrier gas for conveying powder. In a state that a differential pressure between a pressure in the feed tank 11 and a pressure in the powder conveying pipe 31 is controlled to be constant by the internal pressure control valve 22, the powder valve 21 controls a powder flow rate in the powder conveying pipe 31 to be constant. After the powder flow rate is controlled by the powder valve 21, the internal pressure control valve 22 controls the differential pressure so that the powder flow rate becomes constant with the powder valve 21 at a constant opening.
    • 要解决的问题:提供一种能够在短时间内精确控制供给粉末的量的粉末供给装置和粉末供给方法。粉剂供给装置1包括:粉末阀21,其与粉末输送 管31; 内部压力控制阀22,其连接到进料罐11并控制进料罐11中的压力; 和载气主管33,其与粉末输送管31连接并引入用于输送粉末的载气。 在通过内部压力控制阀22将进料罐11中的压力与粉末输送管31中的压力之间的压力控制为恒定的状态下,粉末阀21控制粉末输送中的粉末流量 管31恒定。 在通过粉末阀21控制粉末流量之后,内部压力控制阀22控制压差,使得粉末流量在恒定的开度下变得恒定。
