    摘要: A method for drying erythritol crystals having a moisture content of from 1 to 10% by weight to reduce to the moisture content of 0.15% by weight or below, which comprises drying under fluidized state wherein a temperature of a gas to be used in the fluidized drying is controlled within a range of from 10.degree. to 60.degree. C. at least until the moisture content of said crystals is reduced to 0.5% by weight or below.The moisture content of erythritol crystals (moisture content: 1 to 10% by weight) can be highly efficiently reduced to 0.15% by weight or below in a stable form without deteriorating the crystalline properties and form by fluidized drying said erythritol crystals with the use of a gas flow of a relatively low specific temperature.
