Problems solved by technology

At present, almost all rock sugar production enterprises in China further extract sucrose from the rock sugar mother liquor to produce products such as cotton white sugar, brown granulated sugar and brown sugar. high, the crystallization time is getting slower and slower, the purity of sucrose is getting lower and lower, the color value is getting higher and higher, and the burnt smell is becoming more and more obvious. precious sugar resources; and the produced cotton white sugar, brown granulated sugar and brown sugar not only have poor product quality, but also disrupt the market order.
[0003] The final mother liquor after multiple extractions of sucrose is rarely used, and often no one buys it. Some companies have to throw it away. Because the low-quality rock sugar mother liquor is difficult to handle, it increases the capital occupation of the company, and this has become the most popular rock sugar at present. The bottleneck of the production of enterprises, so, to deal with the mother liquor of rock sugar has become an urgent problem to be solved by all rock sugar production enterprises

Embodiment 1

[0034] A kind of syrup, it is the syrup obtained after the mother liquor after the crystallized rock sugar has been crystallized in the process of preparing rock sugar is activated carbon;

[0035] The preparation method is:

[0036] (1) Dilute the mother liquor to a Brix of 47%;

[0037] (2) Insulation deodorization and decolorization: add the diluted mother liquor into the deodorization tank, add 0.5% activated carbon of the mother liquor mass into the deodorization tank, control the temperature at 63°C, and keep it for 40 minutes;

[0038] (3) Filtration: filter the mother liquor after heat preservation, deodorization and decolorization;

[0039] (4) Concentration: Concentrate the filtrate obtained in step (3) until the Brix is ​​60% to 70%.

[0040] The properties of the syrup prepared in this embodiment are shown in Table 1 below.

[0041] Table 1

[0042]

Embodiment 2

[0044] The invention relates to syrup, which is the syrup obtained by sulfur bleaching the mother liquor after crystallization of single crystal rock sugar in the process of preparing rock sugar, and then adsorbing by active carbon.

[0045] The preparation method is:

[0046] (1) diluting the mother liquor to a Brix of 48%;

[0047] (2) Perform sulfur bleaching on the diluted mother liquor, the sulfur bleaching time is 3 seconds, the sulfur bleaching temperature does not exceed 75°C, and the pH value of the mother liquor is not lower than 5;

[0048] (3) Introduce the sulfur-bleached mother liquor into the deodorization tank, add activated carbon and filter aid, keep warm in the deodorization tank at 65°C and stir and mix for 50 minutes to obtain carbon-containing syrup, and filter the carbon-containing syrup with a plate and frame filter press Filter to obtain the clear juice, and concentrate the clear juice until the Brix is ​​75%;

[0049] The addition of activated carbo...

Embodiment 3

[0054] A kind of syrup, it is the syrup obtained after sulfur bleaching the mother liquor after the crystallization of single crystal rock sugar in the process of producing rock sugar, then carrying out active carbon adsorption, and then using decolorizing resin to absorb;

[0055] The preparation method is:

[0056] (1) diluting the mother liquor to a Brix of 48%;

Abstract

The invention discloses syrup. The syrup is prepared by comprising the steps: performing activated carbon adsorption to mother liquor obtained after crystallization of single-crystal sugar in a crystal sugar preparation process; or, firstly sulfitating the mother liquor obtained after crystallization of single crystal sugar, then carrying out activated carbon adsorption, and then adsorbing with discolored resin, to obtain syrup. According to the syrup, the purity of cane sugar in the syrup is greatly improved, the application field of products is wide, the decomposition reaction of cane sugar can be reduced, and the hyperchromic reaction of glucose and fructose can be decreased; the syrup treatment cost is greatly lowered, in addition, after the purity of the treated cane sugar is improved, the selling price is greatly increased, and the economic benefits of enterprises can be increased; the production efficiency is enhanced; the comprehensive utilization rate of cane sugar can be improved, and the lack situation of cane sugar in China can be improved; and waste syrup does not exist, and the environment pollution can be decreased.

Description

technical field [0001] The invention relates to the technical field of syrup preparation and processing. Background technique [0002] Rock sugar is made of white granulated sugar as a raw material, which is dissolved in water to make a saturated aqueous solution. Under the condition that the temperature gradient and the concentration gradient are the same, polycrystalline rock sugar is first made through natural crystallization. Then, the mother liquor separated from the polycrystalline rock sugar is subjected to forced crystallization through a swinging crystallization tank under the conditions of vacuum evaporation, seeding and vibration to generate single crystal rock sugar. The first single-crystal rock candy and the second single-crystal rock candy generally go directly to the market for sale, while the third single-crystal rock candy is generally used as part of the seeds of the first two single-crystal rock candies. After repeated crystallization and extraction, the...
