Abstract
A preliminary treatment of sliced sugar beets before they are subjected to diffusion comprises a first stage wherein the sliced sugar beets are contacted with a first solution of calcium monosaccharate while the sliced sugar beets and the calcium monosaccharate solution flow countercurrently to each other, and a second stage wherein the sliced sugar beets are contacted with a second solution of calcium monosaccharate while the sliced sugar beets and the calcium monosaccharate solution flow concurrently with each other.
Claims10
A process for the preliminary treatment of sliced sugar beets before they are subjected to extraction of sugar by diffusion, which comprises
- (a) contacting the sliced sugar beets with a first solution of calcium monosaccharate, said contacting occurring in a first stage while the sliced sugar beets and the calcium monosaccharate solution flow countercurrently to each other;
- (b) contacting the sliced sugar beets with a second solution of calcium monosaccharate, said contacting occurring in a second stage while the sliced sugar beets and the calcium monosaccharate solution flow concurrently with each other;
- and
- (c) transporting said sliced sugar beets from said concurrent flow second stage to an extraction stage.

An apparatus for the preliminary treatment of sliced sugar beets before they are subjected to extraction of sugars by diffusion, which comprises
- (a) a first treatment stage having means for transporting said beets from the upstream end to the downstream end, and having means for simultaneously transporting a first solution of calcium monosaccharate from the downstream end to the upstream end, and having first treatment means wherein the sliced sugar beets are contacted with said first solution of calcium monosaccharate while the sliced sugar beets and the calcium monosaccharate solution flow counter-currently to each other;
- (b) a second treatment stage having means for transporting said beets from the upstream end to the downstream end, and having means for simultaneously transporting a second solution of calcium monosaccharate from the upstream end to the downstream end, and having second treatment means wherein the sliced sugar beets are contacted with said second solution of calcium monosaccharate while the sliced sugar beets and the calcium monosaccharate solution flow concurrently with each other;
- and
- (c) means for transporting said sliced sugar beets from said concurrent flow second treatment stage to an extraction stage.

- (a) contacting the sliced sugar beets with a first solution of calcium monosaccharate, said contacting occurring in a first stage while the sliced sugar beets and the calcium monosaccharate solution flow countercurrently to each other, the treatment conditions being so selected that the first solution contains substantially no calcium monosaccharate after the solution has reacted with the sliced sugar beets;
- (b) contacting the sliced sugar beets with a second solution of calcium monosaccharate, said contacting occuring in a second stage while the sliced sugar beets and the calcium monosaccharate solution flow concurrently with each other;
- and
- (c) transporting said sliced sugar beets from said concurrent flow second stage to an extraction stage.
