Crude juice purification with reduced lime consumption

Device comprising:

• a first alkalinization container for preliming, wherein the first alkalinization container comprises an inlet for a crude juice, a metering device for metering lime milk, and an outlet for a preliming juice;
• a second alkalinization container for a first mainliming, wherein the second alkalinization container comprises an inlet for a preliming juice, a metering device for metering of lime milk, and an outlet for a limed crude juice, and wherein the second alkalinization container inlet connects to the outlet of the first alkalinization container;
• a first heat exchanger for heating a limed crude juice, wherein the heat exchanger comprises an inlet for limed crude juice and an outlet for heated limed crude juice, and wherein the heat exchanger inlet directly connects to the outlet of the second alkalinization container, and the heat exchanger outlet connects to the inlet of a first separation device for clarification of a the heated limed crude juice and separation of a non-sucrose substance containing fraction,
• a second separation device for the concentration of a non-sucrose substance containing fraction and separation of a sucrose-containing fraction, wherein the second separation device comprises an inlet for a non-sucrose substance containing fraction, and a first outlet for a concentrated non-sucrose substance containing fraction, and a second outlet for a clear sucrose-containing fraction, and wherein the second separation device inlet connects to the outlet of the first separation device,
• wherein the first separation device is a static or dynamic decanter which comprises an inlet for a limed crude juice, an outlet for a non-sucrose substance containing fraction, and an outlet for a clarified limed crude juice.
