The evaporation process in the nira with vacuum evaporator using barometric condenser requires considerable energy, to save energy, it is necessary to design a vacuum evaporator that can decrease the point also energy-saving by replacing the barometric condenser into Liquid Ring Vacuum Pump method where the vapor has been condensed in the condenser is flown to the vacuum pump to draw steam in the evaporator chamber so that vacuum conditions occur. This type of vacuum pump uses a small energydoi:10.11594/nstp.2018.0133 fatcat:kiyb4dxhmjaqzn7iubguq2rw4q
