Problems solved by technology

[0006] (1) After the milk of lime is filled with syrup, it is only filtered by plate and frame, which cannot effectively remove impurities such as non-sugar substances, macromolecular pigments, colloids, and proteins;
[0007] (2) The finished sugar obtained by sulfur bleaching and decolorizing the sugar solution with sulfur dioxide, there is SO 2 The residue is high, it will turn yellow after a period of storage, the solution has quality problems such as flocs after a period of storage, and the SO in the production process 2 Into the atmosphere, it will cause a burden to the environment;
[0008] (3) Failure to effectively remove the salt produced during the sugar making process, resulting in an increase in ash content in the product and a decrease in quality;
[0009] (4) Concentration, crystallization, separation, and drying process equipment in raw sugar processing are cumbersome and require a lot of water, steam, electricity and other resources;
[0010] (5) The crystalline sugar produced needs to be redissolved once when used by some downstream customers. Such repeated dissolving, crystallizing and redissolving processes not only make the process cumbersome, but also easily cause a large loss of sugar, thereby increasing production cost
At present, the production process of powdered sugar is mainly based on the production process of crystallized sugar, that is, the crystallization method, and finally crushed and sieved. Starch affects its texture and taste, thus limiting its scope of application

Embodiment 1

[0042] As shown in Figure 1, the preparation process of a high-quality syrup and powdered sugar of the present invention comprises the following steps:

[0043] (1) Pretreatment

[0044] a. Sugar melting Dissolve raw sugar in water to obtain raw sugar syrup; the temperature of sugar melting is 75°C, and the brix of raw sugar syrup is 55°Bx;

[0045] b. Purification Pass lime milk and raw sugar syrup into the purification system, slowly introduce carbon dioxide to fill, and form calcium carbonate precipitation to remove non-sugar substances; the Baume degree of lime milk is 18°Be, and the pH of the filling syrup is 8.0.

[0046] c. The filtered and filled syrup enters the filtration system, and first enters the clarifier (plate and frame filter press) to obtain clear and transparent syrup, and then performs precision filtration through the ultrafiltration membrane to remove non-sugar substances, macromolecular pigments, colloid, protein and other impurities to obtain clear jui...

Embodiment 2

[0070] As shown in Figure 1, the preparation process of a high-quality syrup and powdered sugar of the present invention comprises the following steps:

[0071] (1) Pretreatment

[0072] a. Sugar melting Dissolve raw sugar in water to obtain raw sugar syrup; the temperature of sugar melting is 75°C, and the brix of raw sugar syrup is 60°Bx;

[0073] b. Purification Pass lime milk and raw sugar syrup into the purification system, slowly pass in carbon dioxide for full filling, and generate calcium carbonate precipitation to remove non-sugar substances; lime milk Baume degree 18°Be, full filling syrup pH8.0 .

[0074] c. After the filtered and filled syrup enters the filtration system, it first enters the clarifier (plate and frame filter) to clear the transparent syrup, and then conducts precision filtration through the ultrafiltration membrane to remove non-sugar substances, macromolecular pigments, Colloid and protein and other impurities are removed to obtain clear juice; ...

Abstract

The invention relates to the technical field of the making of sugar, and particularly discloses a preparation method of high-quality syrup and powdered sugar. According to the preparation method of the high-quality syrup and powdered sugar, raw sugar is used as a raw material. The preparation method is characterized by comprising the following steps of dissolving the raw sugar by using water, so as to obtain raw-sugar syrup, introducing lime milk and the raw-sugar syrup together into a purification system, slowly introducing carbon dioxide into the purification system to carry out carbonation, making carbonated syrup enter a filtration system, and making the carbonated syrup first enter a clarifier and then pass through a hyperfiltration membrane, so as to finally obtain clear juice; subjecting the clear juice to discoloration, desalination and condensation treatment in sequence, so as to obtain target syrup; carrying out spray drying on the desalinated clear juice, so as to obtain the powdered sugar, cooling the powdered sugar, and then compounding the powdered sugar, so as to obtain a final product. The preparation method has the characteristics that the operation is simple (crystallization, evaporation and dissolution are not needed); the energy consumption is low; the cost is low; the product quality is stable and favorable.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of sugar production, in particular to a method for preparing high-quality syrup and powdered sugar. [0003] (2) Background technology [0004] Sucrose is an indispensable sweetener and nutrient for human life. The annual consumption of sugar per capita in the world is about 20kg, most of which is sucrose. my country is one of the major sugar producing countries in the world. At present, there are two main sugar production process routes at home and abroad: one is to directly produce white sugar from sugarcane or sugar beet, that is, cultivated white sugar, that is, "one-step" sugar production; That is, "two-step" sugar production. [0005] The main processes of raw sugar processing and refined sugar include raw sugar redissolution, clarification, decolorization, concentration, crystallization, separation, drying, packaging, etc., among which the most important is the clarification and decoloriza...
