る粉体供給装置。 After pressurizing a relatively low-pressure lock hopper connected to the high-pressure hopper via an airtight valve, the airtight valve is opened to allow the powder to fall from the lock hopper to the high-pressure hopper, and then the airtight valve is opened. In a powder supply device that closes and supplies powder at high pressure from a high-pressure hopper to a powder feeding pipeline, the airtight valve is provided so that a space between an upper airtight seal and a lower airtight seal can communicate with the atmosphere. A powder supply device comprising an air bleed pipe and an on-off valve provided in the middle of the air bleed pipe.
