This utility model relates to the technical field of flash evaporation equipment, in particular to an improved flash evaporation feeding device, comprising a chain conveyor, a paddle-type twin-screw conveyor is arranged at the lower part of one end of the chain conveyor, a material pusher is arranged below one end of the paddle-type twin-screw conveyor, a shear mixing feeder is arranged at the bottom end of the material pusher, an intermeshing twin-screw feeder is arranged at the bottom end of the shear mixing feeder, and one end of the intermeshing twin-screw feeder is connected with a flash evaporation device. In the improved flash evaporation feeding device, the paddle-type twin-screw conveyor is used after the chain conveyor, which can break large pieces of materials and effectively reduce the blockage and adhesion of large pieces of materials to the subsequent conveying line. Moreover, the barrel of the twin-screw extruder is provided with a jacket, which can heat cold materials by introducing steam and cool hot materials by introducing cooling water; the twin-screw conveyor is equipped with a frequency converter to adjust the feeding speed; the twin-screw conveyor has a forward and reverse switching function, which is more convenient when the discharged material is stuck.
