Problems solved by technology

This sugar beet pulp is difficult to ferment and therefore difficult to store in storage
Coupled with the fact that these processes used are somewhat large-scale and require cumbersome and expensive equipment, thereby increasing the cost of the processed product

Embodiment approach

[0069] according to figure 2 In the first embodiment shown, the plant 10 for carrying out the sugar beet processing process additionally makes it possible to obtain two end products, i.e. on the one hand a mixture of press cake and filter cake and on the other hand a filtered syrup with About 90% purity and more than 60% dry matter content, brown in color. Such as figure 2 As shown, the sugar beet 11 enters the cleaning device 12 . These washed beets 11 a are optionally chopped in a chopping device 13 . Preferably, the washed whole 11a or shredded 11b beets are then heated in a heating device 14, for example consisting of a 100°C steam pan. The heated 11c whole or chopped sugar beet then enters a pressing device 15, for example a twin-screw press known to a person skilled in the art, which performs a partial pressing so that at the outlet two separate products are obtained: on the one hand a relative Sugar beet press cake 11d with a dry matter content of more than 20% su...

Abstract

The invention relates to a beet processing process comprising at least the following steps: washing of the beets; partial pressing of the beets for the production, on the one hand, of a sugar-containing press cake at more than 20% relative to the dry matter content and, on the other hand, of a sugar juice at a concentration greater than 15% dry matter content; separation of the press cake and of the sugar juice. The invention also relates to animal nutrition, fermentation substrates and edible sugar based on the products obtained from this beet processing process.

Description

technical field [0001] The present invention relates to a sugar beet processing process and plant to produce sugar juice and beet press cake, also called product NA, which can be upgraded in various forms, especially as animal feed, as fermentation substrate and as crystallized sugar. Background technique [0002] Beets contain about 23% dry matter content, currently it is based on figure 1 Processed according to the traditional sugar diagram shown, producing juice on the one hand and slurry on the other. [0003] The beets are first cleaned and shredded before being sent to a large-capacity extractor in which hot water circulates in countercurrent. The sugars contained in the couscous require sufficient contact time to pass into the water; this is known as leaching. Once this step is complete, two products are produced: "sugar-lost" beet pulp and sugar-laden water, also called leach juice, which needs to be purified following the lime-carbon separation process, concentrat...
