Abstract
Official abstract text for this publication.
The present invention relates to a process for purifying beet sugar juice and more particularly sugar juice obtained by pressing beets. It also relates to the purified juice and to the uses thereof, in particular as a fermentation substrate and for preparing granulated sugar. The purification process according to the invention comprises a step of passing the juice to be treated through a cellulose-fibre-based pre-layer. This process can be improved when the juice to be treated comprises between 0.1% and 4% of cellulose fibres.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for purifying beet sugar juice comprising: (a) combining the beet sugar juice and cellulose fibers at a content of between 0.1% and 4% by weight; and, (b) passing the beet sugar juice and cellulose fiber combination through a filtration precoat which consists of 100% of cellulose fibers. 2. The process as claimed in claim 1 , wherein the cellulose fiber content is preferentially between 0.2% and 3% by weight. 3. The process as claimed in claim 1 , wherein the filtration is carried out by means of a scraped precoat rotary filter. 4. The process as claimed in claim 1 , wherein the filtration is frontal. 5. The process as claimed in claim 1 , wherein the filtration step is preceded by a centrifugation step.
