Abstract
The present invention relates to an improved method for the purification of crude sugar beet juice. The present invention relates moreover to methods for the manufacture of non-sucrose substance combinations from crude sugar beet juice, as well as two devices for the purification of crude sugar beet juice. The measures according to the invention allow a reduction of lime consumption during the purification.
Claims8
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 the 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 the limed crude juice, wherein the heat exchanger comprises an inlet for the 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,
- a first separation device for clarification of the heated limed crude juice and separation of a non-sucrose substance containing fraction, wherein the first separation device is a static or dynamic decanter which comprises an inlet for the heated limed crude juice, a first outlet for the non-sucrose substance containing fraction, and a second outlet for a clarified limed crude juice, wherein the inlet of the first separation device connects to the outlet of the first heat exchanger, and
- a second separation device for the concentration of the non-sucrose substance containing fraction and separation of a sucrose-containing fraction, wherein the second separation device comprises an inlet for the 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 first outlet of the first separation device,
- wherein the second outlet of the second separation device connects to the inlet of the first heat exchanger and is configured to feed fluid from the second outlet of the second separation device to the inlet of the first heat exchanger.
