おける原料排出構造に関する。Detailed Description of the Invention The present invention provides a rotatable scraper in a raw material storage chamber formed in the shape of a rotating body on the rotor of a rotary valve, prevents raw materials from adhering to the wall surface of the raw material storage chamber, and supplies the raw material to the raw material storage chamber. The present invention relates to a raw material discharge structure in a rotary valve configured to discharge the entire amount of raw raw material.

いる。Rotary valves, which have multiple raw material storage chambers on the outer periphery of the rotor and connect devices with different pressures to transfer raw materials such as powder and granules, are used for, for example, denaturation processing of proteins and starches under high pressure. It is often used for supplying or discharging raw materials.

かった。As a countermeasure against this problem, many rotary valves have been proposed in which a piston is reciprocated in a raw material storage chamber of a rotor to forcibly discharge the raw material in the chamber. It is true that all of the raw material in the raw material storage chamber is discharged in such devices, but in both devices, the movement of the piston is impactful, which places a large load on each part of the device, and the structure is complex. The device had many parts and was not completely satisfactory.
