The invention discloses a refining and feeding device. The refining and feeding device comprises a hopper and a conveying device, and a hopper rotating frame is arranged below the hopper. A roller isarranged on the front lower part of a discharge hole of the hopper, and a set of material combing teeth are arranged on the roller. An elastic support and a hopper overturn limiting structure are arranged at the end, away from the discharge hole, of the hopper. The conveying device at least includes a first horizontal conveying section located below the roller, a lifting section which is connectedwith the first horizontal conveying section in an engagement mode, and a second horizontal conveying section located after the lifting section, and the lifting section is inclined and arranged at anacute angle relative to the first horizontal conveying section. The refining and feeding device has a simple structure, skillfully utilizes the joint action of the hopper, the roller and various typesof comb teeth disposed on the roller for refining, and further refines materials by using the lifting section of the conveying device, so that the material distribution is more uniform, and the refining and feeding device can be widely used in the fields of tea processing and feeding and refining processing of agricultural and sideline products and other materials.
