Abstract:
A powder supply device includes a controller configured to receive an output from a load cell and an output from a pressure indicator, wherein the controller obtains a powder weight or a rate of change in the powder weight in a feed tank on the basis of a value obtained by subtracting a value proportional to the output from the pressure indicator from the output from the load cell and controls the flow rate of the powder to be supplied to outside of the feed tank on the basis of the powder weight or the rate of change in powder weight in the state in which a closing valve is closed.
