摘要： A vacuum packaging method and device are provided. The device comprises a device body, a control system, and a door, a vacuum pump set, a pressure sensor, and a gating switch, which are respectively electrically connected with the control system. The method comprises acquiring size information of a package and selecting a suction constant b; controlling a door to seal the vacuum chamber after the package is disposed into a vacuum chamber; actuating a vacuum pump set and starting timing, and recording time node ti when a pressure detected inside the vacuum chamber is lowered to a first preset pressure P 1 ; continuously performing suction by the vacuum pump set, and recording time node t 2 when the pressure detected inside the vacuum chamber is lowered to a second preset pressure P 2 ; calculating time difference Δt by a formula Δt=t 2 -t 1 based on ti and t 2 ; obtaining total suction time T or suction-stopping pressure P based on Δt and b; continuously performing suction by the vacuum pump set, and controlling the vacuum pump set to stop suction once a suction time reaches T or the pressure inside the vacuum chamber is lowered to P; controlling a heater to finish heat-sealing. It has simple and reliable algorithm, reduces calculation error, and achieves quick calculation.
