摘要： A method for producing high purity D-psicose crystals having a purity of 98% (w/w) or more and a grain size of MA200 or more. The method includes: removing impurities from a D-psicose solution to obtain a purified D-psicose solution; concentrating the purified D-psicose solution; cooling the concentrated D-psicose solution to 30° C. to 40° C. through a heat exchanger; seed crystallizing the D-psicose solution at 30° C. to 40° C. to obtain a seed crystallized massecuite; and full-scale crystallizing the seed crystallized massecuite. The method can produce pure D-psicose crystals in a suitable form for industrial application through an economical crystallization process from the D-psicose solution without using organic solvents.

摘要： The invention generally relates to systems with anti-fouling control and methods for controlling fouling within a channel of a plug flow crystallizer. In certain aspects, the invention provides a system that includes a plug flow crystallizer having a channel, one or more heating/cooling elements, each operably associated with a different segment of the channel, and a controller. The controller is operably coupled to the one or more heating/cooling elements and configured to implement a temperature profile within the channel of the plug flow crystallizer that grows crystals in a plug of fluid that flows through a first segment of the channel and dissolves encrust in a second segment of the channel while having minimal impact on crystal growth in the plug of fluid in the second segment of the channel. In certain embodiments, these segments may be cyclically alternated, in that the segment in which crystal grows in one cycle becomes the segment in which crystal dissolves in the next cycle and vice versa, to realize a fully continuous crystallization process.

摘要： A method for producing a nanoparticle to separate a diketopyrrolopyrrole pigment includes separating an α-type diketopyrrolopyrrole pigment nanoparticle having high crystallinity by carrying out separation of the diketopyrrolopyrrole pigment and crystal type transformation to the α-type with substantially a single step. The α-type diketopyrrolopyrrole pigment nanoparticle is separated by mixing a diketopyrrolopyrrole pigment solution having the diketopyrrolopyrrole pigment dissolved in a solvent and an alcohol solvent containing an alcohol compound solvent in a thin film fluid formed between at least two processing surfaces 1 and 2 arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other. An acidic substance is contained in at least any one of the diketopyrrolopyrrole pigment solution and the alcohol solvent at this moment.
