Abstract:
1. An apparatus for crystallizing a substance, comprising: (a) a retention stretch, having a first end and a second end, (b) a segmenter, for producing a segmented stream which consists of alternating segments of a solution of the substance and of a transport medium, and for introducing said segmented stream into the first end of said retention stretch, so that said segmented stream passes form said first end to said second end of said retention stretch, and exists from the second end of the retention stretch, (c) means for cooling the retention stretch, to thereby bring about crystallization of the substance in the segments of solution, in the segmented stream, as said segmented stream passes through the retention stretch, and (d) a separator, for separating the crystals of material from the segmented stream as it exits from the second end of the retention stretch.
