Abstract: A magnetic transfer device and method are provided. A magnetic field generating structure comprises a pair of permanent magnets connected to a return yoke. Respective magnetic poles of the magnets, of a different polarity from one another, oppose each other with a conjoined body disposed therebetween. The magnetic field generating structure is moved from a position at an outer periphery of the conjoined body, to a position at an inner periphery of the conjoined body, and then moved from the position at the inner periphery across the conjoined body toward the outer periphery, to a position outside of the conjoined body. The return yoke is positioned at a radially more outward position, toward the outer periphery, than are the permanent magnets. The movement of the magnetic field generating structure is carried out while maintaining a constant distance from the rotating conjoined body.

Abstract: The invention provides a process for producing the crystals of difructose dianhydride III (DFA III), namely a indigestible disaccharide where two fructose molecules are bonded to each other at positions 1,2′ and 2,3′(di-D-fructofuranose-1,2′:2,3′-dianhydride), where solutions containing DFA III are adjusted to and/or maintained at pH 5 or more, preferably pH 5 to 8, and more preferably 6 to 8. In accordance with th invention, DFA III can be produced industrially without lowering the crystal yield even when the crystallization thereof is done in a recycling system; additionally by adjusting the total fructose content in mother solutions for (crude) crystallization to 5% or less per a solid content basis and adjusting the fructose content to 1% or less, DFA III can more effectively be produced.
