Powdery product e.g. cereal, flow speed regulator for pipe, has hopper arranged in circulation flow to create braking action on material flow across outlet orifice of hopper, and another action above level of inlet orifice of hopper

摘要

The regulator has a regulation chamber (2) including an inlet (3) for a material and an outlet orifice. A hopper (5) provided inside the chamber is open at its two ends. The hopper is arranged in a circulation flow to create a braking action on material flow across an outlet orifice (5B) of the hopper, and another action above the level of an inlet orifice (5A) of the hopper.
