摘要:
A method for producing a powder containing xylitol crystal particles and another polyol including a mixture containing a xylitol syrup and another polyol, whose dry material content is equal to or greater than 95% by weight, xylitol content ranges from 85 to 97.5% by weight and the other polyol content ranges at least from 15 to 2.5% by weight with respects to the dry material. The method includes: obtaining the mixture by simultaneously dispersing the xylitol and the other polyol syrup and xylitol-containing germs in an open rotating vessel containing xylitol-based granules, mixing the xylitol and the other polyol syrup and xylitol-containing germs on the surface of the xylitol-containing germs contained in the vessel, removing the xylitol-based granules and the other polyol from the vessel and crystallizing the xylitol and other polyol contained in the granules.

A crystalline mixture solid containing maltitol having an oil absorptivity of 0.1 to 6.9 wt % and a bulk density of 0.60 to 0.75 g/cc when it is ground and classified to ensure that at least 70 wt % of the obtained particles should have a particle size of 16 to 50 mesh and a process for producing a crystalline mixture solid containing maltitol, comprising introducing air bubbles into a maltitol aqueous solution. According to this process, a crystalline mixture solid containing maltitol having high solubility and almost no moisture absorption is produced at a high work efficiency and a low cost in a short period of time.

The present invention relates to a process for continuously crystallizing fructose anhydride using a seed crystallization tank and a crystallization tank separated from each other, comprising feeding an aqueous fructose solution containing at least 90% of fructose and containing at least 87 W/W % of solid and an aqueous solution containing a great deal of crystals in an amount of 0.5 to 5 times that of said fructose solution into a seed crystallization tank equipped with a high speed agitator, mixing the mixture at 40.degree. to 50.degree. C. at a high speed, introducing the obtained mixture into a crystallization tank and gradually cooling the mixture under condition under which new crystals do not form spontaneously to thereby grow the crystals. The present invention can realize the crystallization at a low temperature of 40.degree. to 50.degree. C. or below and prevents the decomposition and the polymerization of fructose which often occur above 50.degree. C. by mixing an aqueous fructose solution and a great deal of crystals at a high speed, whereby large and uniform crystals of fructose anhydride can be obtained in an enhanced yield.
摘要:
A seeding magma for seeding a solution of a crystallizable product is prepared from a suspension the crystals in a liquid phase. This suspension is delivered into a continuously rotating conical basket of a centrifugal drier. The basket has an upper output end and a screen is mounted therein. Rotation of the basket causes the suspension to be subjected to centrifugal forces causing crystals of a size interior to the mesh size of the screen to pass with the liquid phase through the screen and larger crystals to be retained on the screen and centrifugally displaced towards the upper output end and ejected therefrom. These crystals are forcefully projected against an impact surface disposed around the output end of the basket whereby the projected crystals are crushed on impact with the surface. The crushed crystals are recycled into the suspension delivered into the basket while the liquid phase with the crystals passed through the screen is removed for preparing the seeding magma.
摘要:
An apparatus for continuously crystallizing sugar, both by developing crystals from sugar solutions and by exhausting solutions of mother liquor from a massecuite, or cooked mass, by means of evaporation of said solutions over seed crystals, said apparatus comprising a hollow horizontal cylinder which in its upper portion and over its entire length has connected to itself along a slot a rectangular cover which thus forms a single body; means for heating the exterior of the hollow cylindrical body; means for producing a helicoidal movement in the mass being processed; means for connecting the hollow cylindrical body by means of the rectangular cover to a source of low pressure; means for feeding into the front end a controlled quantity of a solution of sugar or of a massecuite; means for feeding controlled replacement quantities of sucrose solution or of mother liquors to replace the water evaporated and the material crystallized, and to increase the volume of the mass being processed, and means for controlled discharge included in the rear end of the hollow cylindrical body.
摘要:
An improved process in the production of sugar is provided by adding to a sugar solution prior to crystallization calcium acid phosphate, followed by the addition of soda ash. Optionally, in a third step sodium hydrosulfite is added. The resulting sugar is of a high grade, being light colored and substantially free of impurities.
摘要:
A method and a device for obtaining sugar crystals from a sugar solution by concentrating the thick juice emanating from the multi-stage evaporator in a continuously operating pre-concentrator to a concentration at which seed granulate could be added to the boiling pan, by raising the pressure of the concentrated thick juice, by supplying the juice to a buffer vessel in which the juice is subjected to a higher pressure than the pressure at which it is concentrated, the temperature being maintained and the contents of the vessel being thoroughly stirred and by filling the boiling pan from the buffer vessel while simultaneously seed granulate is added.
