Embodiment 1

[0020] The first preferred embodiment of the method for controlling maltitol crystal size of the present invention specifically comprises the following steps:

[0021] (11) Turn on the vacuum pump, and after the vacuum reaches the set value, carry out vacuum evaporation and concentration of the maltitol solution with a content of more than 94.5% at a temperature of 63°C to obtain a supersaturated solution of maltitol with a mass percentage of 75%.

[0022] (12) After the concentration reaches the requirement, add seed crystals at 0.5% of the dry weight of maltitol, and keep stirring for 15 to 20 minutes.

Abstract

The invention relates to a method for controlling the maltitol crystallization granularity. According to the method, firstly, a maltitol solution is evaporated and concentrated into a saturation state; then, seed crystals are added; the maltitol solution is continuously supplemented in a vacuum evaporation state; the brix of massecuite is controlled; the concentrated crystallization is continuously completed; and then, centrifugal drying is performed to obtain maltitol crystals. The crystallization process is controlled by controlling the seed crystal addition quantity and the material supplementing concentration. By the method, the maltitol nucleation can be inhibited; the generation of fine grains can also be reduced, so that the granularity distribution of the finally obtained crystal product is uniform; and the proportion of powdered sugar in the granularity distribution is reduced, so that the agglomeration of the maltitol product is effectively inhabited. The method has the advantages that the crystallization period is shortened; the crystallization efficiency is improved; the granularity of the finally obtained maltitol crystals is uniform and stable; the natural fluidity ofthe product after the drying is good; the agglomeration risk during the storage at a room temperature is reduced; and the method can be used for producing maltitol products with different granularities.

Description

technical field [0001] The invention belongs to the technical field of maltitol crystal preparation, in particular to a method for controlling the grain size of maltitol crystals. Background technique [0002] Maltitol evaporative crystallization is to make the initially incompletely saturated maltitol solution evaporate and concentrate in an evaporative crystallizer, and obtain crystalline maltitol by controlling the conditions of boiling sugar. Crystallized crystals need further operations such as filtration and drying before they can be packaged and sold as products. Crystallization determines the characteristics of the product, the main characteristics of which are the particle size and particle size distribution of the product. Usually, the concentration of particle size distribution of crystal products in the chemical, fine products, pharmaceutical, and food industries can not only improve the dissolution rate, bulk density, and fluidity of the product, but also impro...
