Refining device for feeding opening of tea color separator

The utility model discloses a refining device for a feeding opening of a tea color separator. The refining device comprises a feeding bin, wherein the feeding bin is formed by oppositely connecting an upper conical bin and a lower conical bin; a horn mouth of the upper conical bin is upward; a horn mouth of the lower conical bin is downward; a circle of plastic buffer curtain is arranged on the inner wall of the upper conical bin; a refining screen plate is arranged in the middle of the lower conical bin; airflow holes which are located above the refining screen plate and are distributed in multiple layers at intervals are formed in the outer wall of the lower conical bin; the multiple layers of airflow holes are distributed at intervals along the annular wall of the lower conical bin; and the airflow holes incline towards the refining screen plate. The refining device is novel in structure design; the impact force is reduced by virtue of the plastic buffer curtain; through coordination of the refining plate and the airflow holes, the phenomena of extrusion and accumulation during blanking are reduced; lasting and stable dropping of materials can be ensured, the materials can also be effectively cooled, and the quality of tea production is ensured.
