Abstract:
Control of the flow of granular polysilicon granules is effected by employing an elastomeric pinch sleeve valve. The flow control by this method is especially useful for controlling the flow of silicon seed particles and granular polysilicon product in the fluidized bed method for producing polysilicon. The flow may be stopped without gas leakage, and is suitable for use over long operating campaigns.

Claim (Index 22):
A fluidized bed reactor for production of a granular polysilicon product, comprising:\n a) at least one fluidized bed reactor for the production of granular polysilicon from polysilicon seed particles, b) at least one reservoir vessel for the polysilicon seed particles which is connected to the fluidized bed reactor via an inlet conduit, and c) at least one collecting vessel for the granular polysilicon which is connected to the fluidized bed reactor via an outlet conduit, wherein at least one pinch fitting comprising a pinch-fitting sleeve is disposed in the inlet conduit between the reservoir vessel and the fluidized bed reactor and/or in the outlet conduit between the fluidized bed reactor and the collecting vessel, wherein the pinch-fitting sleeve comprises an elastomer selected from the group consisting of ethylene-propylene-diene rubber, fluorinated elastomer, and a combination of ethylene-propylene-diene rubber and fluorinated elastomer.
