Embodiment 1

[0046] A preparation method of co-crystal maltitol and sorbitol, comprising the following steps:

[0047] (1) Melting sugar: Feed maltitol and sorbitol from the raw material feeding pipe according to the ratio of 1-5:1 in mass ratio, add them to the dissolving tank 2 in the kettle body 1, and then feed them from the raw material feeding pipe to the dissolving tank 2, add water, and pass heat medium into the jacket 4 to raise the temperature inside the kettle body 1 to 110-125 ° C, dissolve for 2-3 minutes, and obtain a mixed liquid of maltitol and sorbitol, turn over the seal of the bottom surface of the dissolution tank 2 2a Plate 8, open the filter hole, vacuum pump 10 to filter the mixed liquid, and set aside; wherein, the maltitol is crystalline maltitol or liquid maltitol with a purity of more than 95%, and the sorbitol is crystalline sorbitol or a liquid with a purity of 98%. The above liquid sorbitol;

[0048] (2) Vacuum sugar cooking: the mixed liquid in step (1) is f...

Embodiment 2

[0063] A kind of reactor with temperature control system, with reference to figure 1 , 2 , including the kettle body, the top of the kettle body 1 is provided with a dissolving tank 2, and the kettle body 1 is provided with a raw material feeding pipe communicating with the inner cavity of the dissolving tank 2, and there are 3 raw material feeding pipes, respectively It is the first feed pipe 3a for maltitol feed, the second feed pipe 3b for sorbitol feed and the third feed pipe 3c for adding water.

Abstract

The invention discloses a preparation method of co-crystallized maltitol and sorbitol and a reaction kettle with a temperature control system. The preparation method includes steps of sugar melting, vacuum sugaring off, co-crystallizing and smashing and drying. Aiming at properties and characteristics of maltitol, maltitol and sorbitol are co-crystallized to obtain the co-crystallized maltitol and sorbitol. A fuzzy neutral network algorithm is utilized to realize accurate control of temperature in the reaction kettle; by combining hardware configuration and software configuration, working personnel only need to be in a control room to accurately control the temperature in the reaction kettle. The preparation method has online self-learning capability and self-adjusting capability, can accurately control the temperature of the reaction kettle and has good robustness. In addition, by the preparation method, stability in temperature control of the reaction kettle can be improved substantially to realize accurate control, raw material waste and defective product generation caused by poor temperature control of the reaction kettle in the production process can be reduced, cost can be saved, and economic efficiency can be improved.

Description

technical field [0001] The invention relates to a preparation method of eutectic maltitol and sorbitol and a reaction kettle with a temperature control system, belonging to the field of sugar industry control. Background technique [0002] Maltitol, also known as hydrogenated maltose, the chemical name is 4-O-α-D-glucosyl-D-glucitol, and the molecular formula is C 12 h 24 o 11 , with a relative molecular mass of 344.31, is a new type of functional sweetener. Because of its low-calorie, non-carious, indigestible, calcium absorption and other physiological properties, it has attracted widespread attention. The sweetness of maltitol is 85% to 95% of that of sucrose, but its calorific value is only 5% of that of sucrose. Therefore, maltitol will not increase blood sugar and cholesterol, and is an ideal sweetener for curative food. At the same time, maltitol has the characteristics of heat resistance, acid resistance, moisture retention and non-fermentation, and basically doe...
