The invention provides a liquid vacuum concentration device and method. The liquid vacuum concentration device comprises a box, an evaporation chamber, a separation chamber, a condenser and a vacuum pump, wherein the box is provided with an internal space; the evaporation chamber is provided with a liquid inlet and a liquid outlet, liquid enters the evaporation chamber through the liquid inlet and is heated in the evaporation chamber, and finally concentrated liquid is discharged outside through the liquid outlet; the separation chamber is communicated with the evaporation chamber through fluid, liquid and bubbles generated by heating the liquid enter the separation chamber from the evaporation chamber to achieve gas and liquid separation in the separation chamber, and liquid obtained after gas and liquid separation flows back to the evaporation chamber from the separation chamber; gas obtained after gas and liquid separation enters the condenser from the separation chamber and is condensed into condensed wat
