Problems solved by technology

However, the above methods have their own defects. US20040258822 needs to add auxiliary materials such as sugar alcohol and maltodextrin, which is unacceptable for customers who want to use pure sucralose. This method also has high equipment performance requirements and product yield. The problem is low, which is not conducive to large-scale production. US7750146 has strict requirements on equipment, and many control parameters are prone to poor results due to initial material changes or parameter adjustment deviations. Therefore, it is difficult to scale up the process, which is not conducive to large-scale production. Production, CN103341339A requires the D97 of the granulated micropowder to be less than 30 microns. Obtaining such a micropowder requires extremely high crushing equipment. In the process of obtaining such a micropowder, it is inevitable to face large dust, easy adhesion to the wall, difficulty in sieving, Production problems such as difficult transportation, so such a premise makes the application subject to obvious limitations

Embodiment 1

[0032] Add 50 kilograms of sucralose with 95% moisture passing through a 100-mesh screen and 0.5% sucralose in the DSH0.3 double-helix conical mixer, start the equipment to stir, the stirring speed is 53rpm, and inject 8 kilograms of sucralose through the spray atomizer 30% sucralose aqueous solution, keep stirring for 6 minutes after completion, release the mixed material and use KZL-100 fast granulator to granulate, wherein the cutting knife rotates at 1000rpm, and the prepared wet granules are input into FG-100 fluidized bed dryer. Fluidized drying at 30°C for 30 minutes, then raised to 40°C to 55°C for fluidized drying to obtain granular sucralose.

Embodiment 2

[0034] Take the refined sucralose crystallization and centrifuge to remove the mother liquor, and obtain a "wet product" with a water content of 3.5%, crush it, pass through a 100-mesh sieve, take 50 kg of the sucralose that has passed the 100-mesh sieve, and add it to GHL-200 for high-speed mixing and granulation In the machine, adjust the stirring speed to 200rpm, the cutting knife speed to 1500rpm, dry mix for 2 minutes, then inject 7 kg of 50% sucralose aqueous solution through the binder hopper, then adjust the cutting knife speed to 2300rpm, and Carry out cutting and granulation at a rotating speed, and dry the prepared wet granules in an RXH-27-B hot air circulation oven at 45°C to 56°C to obtain granular sucralose.

Embodiment 3

[0036] Add 50 kilograms of sucralose with 98% moisture passing through a 150-mesh screen and 0.3% sucralose in the GSL-200 high-efficiency wet mixing granulator, adjust the stirring speed to 180rpm, and the cutting knife speed to 1500rpm. The spray atomizer injects 8 kg of binder, wherein the binder is a sugar solution obtained by mixing and dissolving sucralose with a water content of 0.25%, ethanol and water in a ratio of 1:1:1 (weight ratio). Then adjust the speed of the cutting knife to 2700rpm, and cut and granulate at this speed. The wet granules are sized with a sieving machine and then input into the FL-120 fluidized bed granulation dryer. Fluidized drying at 60°C to obtain granular sucralose.

Abstract

The invention discloses a preparation method of granular sucralose. The preparation method comprises the following steps: (1) mixing sucralose with a binder to form a mixture; (2) granulating the mixture; (3) drying wet granules to obtain granular sucralose; (4) classifying the dried granules to obtain granular sucralose in one or more granularity ranges; (5) circulating and feeding one part or all classified granules in the one or more granularity ranges to the step (1). The prepared granular sucralose disclosed by the invention has the granularity range within 400 meshes, and is relatively excellent in properties such as thermal stability, fluidity, dissolving performance and caking resistance. The preparation method disclosed by the invention is small in number of process conditions, easy to operate, low in equipment requirement, and applicable to production and amplification.

Description

technical field [0001] The invention belongs to the field of food additives, in particular to the sweetener sucralose, and further relates to a preparation method of granular sucralose. Background technique [0002] Sucralose (Sucralose), chemical name: 4,1',6',-trichloro-4,1',6',-trideoxygalactose, is a high-strength product made by selective chlorination of sucrose The sweetener, whose sweetness is about 600 times that of sucrose, has many characteristics such as pure taste, sweetness similar to sucrose, low calorie value, high safety, good solubility and stability, etc., and has been approved by more than 120 countries Approved for use, and used in more than 3,000 kinds of food, health products, medical and daily chemical products. [0003] Sucralose is usually marketed as raw crystalline powder or in crushed form. Regardless of the above-mentioned product forms, they are faced with problems such as poor fluidity, large dust, adhesion to the wall, electrostatic adsorpti...
