The invention relates to a feeding device. The feeding device comprises a shell, an extruding mechanism and a discharging mechanism, wherein an extruding groove is formed in the shell; a discharging channel is formed in one end of the extruding groove; a discharging opening is formed in the bottom of the discharging channel; the extruding mechanism comprises an extruding pushing block and an extruding driving unit; the extruding pushing block is arranged in the extruding groove; the extruding driving unit drives the extruding pushing block to move along the extruding groove; the discharging mechanism comprises a discharging pushing block and a discharging driving unit; and the discharging driving unit drives the discharging pushing block to move along the discharging channel. According to the technical scheme, a packaging effect of vacuumizing packaging on large flexible particles (such as dried bean curds and Szechuan preserved vegetables) can be improved.
