PURPOSE:To reduce the amt. of granular particles to be spouted with respect to the total time by keeping ejector pressure at a specified value at which clogging is not caused and spouting the particles intermittently. CONSTITUTION:In the method for spouting granular particles, the pressure of air spouted from an ejector nozzle 1 is kept at a value higher than the specified pressure at which the particles are stably spouted. When a spouting amt. of the particles smaller than that under the specified pressure is required, the granular particles are intermittently spouted while keeping the specified pressure, thus the amt. of the granular particles spouted is reduced with repsect to the total time. Consequently, the clogging in the periphery of the ejector nozzle is prevented and a thin film is coated in coating a small amt. of granular particles.
