Embodiment 1

[0021] (1) Add 3000Kg of heavy condensed sugar and 3000Kg of deionized water to the cooking kettle, turn on the steam and heat the cooking kettle to 90°C;

[0022] (2) Add granular activated carbon 500Kg / unit to the decolorization column tower in advance, connect three decolorization columns in series, and turn on the circulation pump to feed the sugar liquid in the cooking kettle to 35M 3 The amount per hour is sent to the decolorization column tower for decolorization, the decolorized sugar liquid is returned to the cooking kettle, and the temperature of the cooking kettle is kept at 90°C; the activated carbon is replaced every 3 tons of decolorized heavy sugar on average, and the replaced activated carbon is heated. It can also process nearly 3 tons of heavy condensed sugar. In summary, it saves half of the activated carbon on average, which greatly saves the cost, increases the utilization rate of activated carbon, and reduces the generation of hazardous waste;

Abstract

The invention relates to a decolorizing method of recrystallized sugar in acesulfame potassium production. The method comprises the following steps: (1) adding the recrystallized sugar and deionized water into a boiling kettle, controlling the mass ratio of recrystallized sugar to deionized water to be 1:(1-1.3), and performing stirring and heating to 85-95 DEG C; (2) adding 500 Kg of granular activated carbon into each decolorizing column tower in advance, feeding the obtained sugar solution into each decolorizing column tower at a speed of 30-40 M<3> / h, returning the decolorized sugar solution to the boiling kettle, and keeping the temperature at 85-95 DEG C all the time; and (3) controlling the water temperature of the jacket of a fine filter to be 95-100 DEG C, feeding the mixed solution of the sugar solution and the activated carbon into the fine filter at 1.2-1.6 M<3> / h, clarifying the obtained filtrate, feeding the clarified filtrate into a crystallization section, and crystallizing the clarified filtrate. The method has the advantages of simplicity in operation, reduction of the labor intensity, high utilization rate of raw materials, realization of cleanness and environmental protection due to pyrolysis regeneration of the activated carbon, shortening of the boiling time by at least half an hour through circular heating using a forced circulation pump, ensuring of continuous production of a workshop section, great increase of the production efficiency, realization of online operation, effectiveness in reduction of impurities, and quality improvement.

Description

technical field [0001] The invention belongs to the technical field of acesulfame potassium production, and relates to a method for decolorizing heavy sugar in the production of acesulfame potassium. Background technique [0002] The traditional decolorization process in the production of acesulfame potassium is as follows: figure 1 As shown, the decolorization section of the current acesulfame-K production process uses powdered activated carbon to decolorize heavy condensed sugar. The heavy condensed sugar enters the cooking kettle from the silo, and it needs to be cooked by manually adding activated carbon. The temperature of the cooking material must reach above 95°C. After one hour of heat preservation, it is filtered through a coarse filter and a fine filter, and then enters the finishing section. The whole process takes a long time to operate, and requires manual feeding of auxiliary materials, which is time-consuming, labor-intensive, high production cost, serious wa...
