Problems to be solved by the invention
However, when the sugar cane is pressed, a large amount of cellulose, calcium pectate, and the like are contained in the raw material sugar as a fine turbid component generated by finely decomposing the cell wall of the sugar cane, plant cellulose, and the like, and it is difficult to remove such a fine turbid component in the sugar washing step or the carbonation step.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a flowchart showing an example of a process for producing a raw material sugar according to embodiment 1 of the present invention, and fig. 2 is a schematic diagram showing an ozone treatment step.
The present invention relates to a process for producing refined sugar as a final purified product from sweet resource crops, and the following description will describe the production process of raw sugar for producing raw sugar from sweet resource crops as example 1 and the production process of refined sugar for refining refined sugar from raw sugar as example 2.
First, as example 1, a process for producing raw material sugar from sweet resource crops will be described.
Fig. 1 shows an example of the case where the sweet resource crop is sugar cane, and as shown in step A1, the harvested sugar cane is cut into small pieces by a cutter, a shredder, or the like, and then the pieces are put into a compressor to be extracted while adding water, thereby refining a sugar solution (juice) containing sucrose (compression step). Next, in step A2, lime is added to the sugar solution (calcification cleaning step), and further, in step A3, a continuous precipitation tank is placed to precipitate impurities (continuous precipitation step).
Next, as shown in step A4, the sugar solution after the continuous precipitation step is subjected to ozone treatment (ozone treatment step).
The ozone treatment step is a step of dissolving ozone gas generated by the ozone generator 1 into the sugar solution. Thus, in the present invention, as shown in FIG. 2, ozone gas having a controlled concentration and flow rate generated by the ozone generator 1 is generated into fine bubbles of 50 μm to 100 μm by using the microbubble generating device 2, and extracted into the sugar solution in the container 3, and the fine bubbles are stirred and mixed into the sugar solution by using the stirrer 4. Here, when the stirrer 4 is used, fine bubbles of ozone can be dispersed in the sugar solution, which is more efficient. As a result, the selective reaction of ozone, in which the fine turbid components (cellulose, calcium pectate, etc.) contained in the sugar solution are decomposed and sucrose is not decomposed, can be efficiently performed. Thus, the decomposed fine turbid components accumulate on the surface of the ozone microbubbles, aggregate into a cake 6, and settle to the bottom of the container 3. Thus, the sugar solution containing the cake 6 is filtered by the filter 7, whereby a sugar solution from which fine turbid components are removed can be obtained.
Next, the syrup obtained by concentrating the sugar solution obtained by the ozone treatment in the concentration step of step A5 is purified.
In the next step A6, the slurry is boiled in a vacuum crystallization tank to prepare sucrose crystals (crystallization step), the sucrose crystals and honey are separated by a centrifuge in the separation step of step A7, and then the sucrose crystals are dried in the drying step of step A8, whereby a raw material sugar having a dark brown color is produced.
The raw material sugar produced in this way is refined into refined sugar in refined sugar factories in various places.
FIG. 3 is a flowchart showing an example of a process for producing refined sugar from raw material sugar according to embodiment 2 of the present invention.
Since the crystal surface of the raw material sugar is covered with a honey film containing a large amount of impurities, the honey film is separated from the crystal surface to remove the impurities in the sugar washing step of step B1. Specifically, a high-concentration sugar solution is added to raw material sugar to dissolve a honey film on the crystal surface, and washed sugar in which the honey film is separated and removed from the crystal surface of the raw material sugar by a centrifuge is purified.
In the bone char step (B5), the ion exchange resin step (B7), the 1 st inspection and filtration step (B6), and the 2 nd inspection and filtration step (B8), when the decolorization ability is insufficient and the color value of the crystallized granulated sugar does not meet the standard, powdered char as a decolorization aid is added to the sugar solution as needed. However, according to the effect of the ozone treatment step (B4) described later, the addition of powdered carbon may be omitted in the case where the decoloring effect in the above step is significantly exhibited.
In the next step B2 of carbonation, lime is added to a sugar solution (stock solution) of a predetermined concentration obtained by adding water to the sugar washing, and carbon dioxide gas is blown into the sugar solution to produce calcium carbonate, so that impurities are adsorbed and removed by the calcium carbonate. In the pressure filtration step B3, the sugar solution obtained by separating calcium carbonate by pressure filtration of the sugar solution after the carbonation treatment is purified.
The ozone treatment step in step B4 is similar to step A4 (see fig. 2) of the process for producing the raw material sugar, and the ozone gas generated by the ozone generator 1 is dissolved in the sugar solution to remove the fine turbid components (cellulose, calcium pectate, etc.). However, since the sugar concentration of the sugar solution subjected to the pressure filtration step is high, the ozone gas is generally hardly dissolved in the sugar solution. Thus, the ozone gas generated by the ozone generator 1 is extracted into a sugar solution having a viscosity of 50 μm to 100 μm by using the microbubble generator 2, and the sugar solution having a fine turbid component removed is purified by stirring and mixing the ozone microbubbles into a sugar solution having a high viscosity by using the stirrer 4 to efficiently perform a selective reaction of ozone.
In the bone char step B5, the sugar solution is decolorized by passing the sugar solution through porous char (bone char) obtained by baking bovine bones. Next, in the 1 st inspection and filtration step of step B6, the sugar solution (crude solution) obtained by removing the fine powdered coal including a plurality of bone charcoals from the sugar solution by the filter by passing the fine powdered coal through the bone charcoals in the bone charcoal step is purified. Further, in the ion exchange resin step B7, the sugar solution (crude solution) is passed through an ion exchange resin to adsorb and remove fine impurities and to remove pigment at an ion level, and in the next step B8, the inspection and filtration step 2 is performed, in the ion exchange resin step, fine substances contained in the sugar solution are removed by a filter by passing through the ion exchange resin, thereby purifying a transparent sugar solution (pure solution: FL).
Next, the purified sugar as a final product is produced through the crystallization step of step B9 of heating/concentrating the transparent sugar solution in a vacuum crystallization tank.
The ozone treatment step may include at least one of a process for producing raw material sugar and a process for producing refined sugar. That is, the ozone treatment step (step B4) of the refined sugar manufacturing process is particularly effective when the refined sugar is manufactured from the raw material sugar manufactured through the raw material sugar manufacturing process without the ozone treatment step (step A4), and when the raw material sugar manufacturing process has the ozone treatment step (step A4) to sufficiently remove the fine turbid components, the refined sugar manufacturing process may be configured without the ozone treatment step (step B4). In addition, even in the case where the raw material sugar manufacturing process includes an ozone treatment step (step A4), since the ozone treatment step is performed doubly in the case where the refined sugar manufacturing process includes an ozone treatment step (step B4), it is possible to refine the sugar solution from which the fine turbid components are more completely removed.
Fig. 4 is a flowchart showing an example of a process for producing a raw material sugar as a modification of example 1. Fig. 4 shows a case where the sweet resource crop is beet (also referred to as beta vulgares, beet).
In step C1, the roots of the washed beets are cut into a predetermined shape in an elongated manner after harvesting (cutting step), and in step C2, the cut beets are immersed in warm water to extract sugar solution after sugar extraction (extraction step). In step C3, the impurities are removed from the sugar solution using carbon dioxide gas and lime as in step B2 (carbonic acid saturation step), and in step C4, the sugar solution after carbonic acid saturation is subjected to pressure filtration as in step B3, thereby purifying the sugar solution from which calcium carbonate is separated (filtration step).
Then, in step C5, the sugar solution is subjected to an ozone treatment step in the same manner as in steps A4 and B4, and the sugar solution from which the fine turbid components have been removed is purified. In step C6, the sugar solution obtained by the ozone treatment is passed through an ion exchange resin to adsorb impurities and remove the impurities, thereby purifying a transparent sugar solution (pure solution) (ion exchange resin step).
Then, in step C7, a transparent sugar solution is heated and concentrated in a vacuum crystallization tank to prepare a colorless transparent sucrose crystal (crystallization step), and in step C8, the transparent sugar crystal is separated by a centrifuge to obtain a sucrose-only crystal (separation step), and in the final step C9, the crystal obtained in the separation step is dried to obtain a raw material sugar as a final product.
As described above, in example 1 and its modification, which illustrate a process for producing raw material sugar by refining raw material sugar from sweet resource crops, an ozone treatment step is provided in step A4 and step C5, and in example 2, which illustrates a process for producing refined sugar by refining raw material sugar, an ozone treatment step is provided in step B4, whereby fine turbid components can be decomposed and removed, and therefore, the carbonation step in steps A2, B2, and C3 can be omitted. Note that, in the case where the carbonation step of step C3 is omitted, the addition of powdered carbon is indispensable.
In example 2, since it is not necessary to reduce the concentration of the sugar solution so as to prevent the filtration pressure from increasing, it is possible to suppress an increase in the amount of vapor used in the crystallization step, and as a result, it is possible to prevent an increase in energy costs, and it is possible to greatly reduce the amount of powdered carbon used, thereby reducing the manufacturing cost.
In example 2, clogging of fine turbid components can be suppressed and the decolorizing ability can be improved in the filter and the ion exchange resin, and therefore, the bone char process in step B5 can be omitted.
In example 2, the addition of powdered carbon can be omitted when step B2 (the carbonation step) and step B5 (the bone-char step) are not omitted, and the addition of powdered carbon is preferably increased when step B2 (the carbonation step) and step B5 (the bone-char step) are omitted.
The operational effects of the configuration of the present invention have been described above based on examples, but the embodiment of the present invention is not limited to the above examples.
In the above-described embodiment, the case where sugar cane and sugar beet are shown as sweet resource crops has been described, but the present invention is not limited to the above-described embodiment, and may be, for example, the case where other sweet resource crops such as sugar rice are used.
