Abstract (en)
[origin: EP0201629A2] 1. Process for continuous crystallization by evaporation in a suspension comprising juice and crystals for sugar production, in which concentrated inflow solution and pied-de-cuite magma are continuously fed into a first treatment space and product magma is continuously drawn off from the last treatment space, with the suspension being guided successively through a plurality of mutually separated round treatment spaces and being subjected to an internal circulatory flow in each treatment space with simultaneous heat supply, and being supplied, with the level controlled, from the individual treatment spaces to the respectively next succeeding treatment space, characterized in that the suspension circulates once in each treatment space in a spiral path which is produced by the superposing of a restricted circular movement caused by feeding in further suspensions about the axis of the treatment space and of a circulatory movement generated by the airlift pump effect occurring in the heating region.
