Claim 6:
7. A continuous production method of producing continuously a product from a powder of a raw material in a continuous production system having a first processor that performs first processing on the powder of the raw material, a second processor that performs second processing on the powder, on which the first processor has performed the first processing, and an inspection and screening device that has an inspection chamber through which powder fed from the first processor to the second processor passes,
the method executing cleansing processing of spraying, at a downstream side of an entrance-side gate valve that opens and closes a path connecting the first processor to the inspection chamber, gas from an entrance-side opening formed on an inner face of the path in a direction forming a spiral flow following the inner face of the path,
wherein the cleansing processing sprays gas from the entrance-side opening in a state in which an exit-side gate valve that opens and closes a path on an exit side of the inspection chamber is open.
