に含まれてしまう。On the other hand, since sucrose solution is easily denatured, if alkali or acid remains in desalted and purified sucrose solution, coloring, alteration, etc. will occur in subsequent steps. In the reverse method, a small amount of alkali or acid is contained in the desalted and purified sucrose solution.

Assuming that the time is B and the regeneration time is B time, a system that regenerates two lines (two lines) while passing one line (one line) when B / A = 1 to 2 is required. . In other words, since the regeneration time of the mixed bed tower is long, three lines (three lines) or more of mixed bed towers are required to constantly pass one line.

る。As a method for confirming whether most of the ions of the sucrose solution have been removed by an anion column filled with a strongly basic anion exchange resin and a cation column filled with a weakly acidic cation exchange resin, a cation column is used. What is necessary is just to measure the electric conductivity of the processed sugar solution that has passed, and thereby, it is possible to know a decrease in the ion removing ability of the anion tower and the cation tower. Then, when the electric conductivity of the treated sugar solution passing through the cation tower exceeds a certain value, the flow of the sucrose solution to the anion tower and the cation tower is stopped, and the strong basic anion exchange resin of the anion tower is used. What is necessary is just to regenerate the weakly acidic cation exchange resin of a cation tower. When the decrease in the ion exchange resin capacity is detected in this way, the passage of the sucrose solution is immediately stopped,
By performing regeneration treatment of anion tower and cation tower,
It is possible to reduce the load on the mixed-bed column packed with the strongly basic anion exchange resin and the weakly acidic cation exchange resin in the latter stage.

In order to regenerate the strongly basic anion exchange resin in the anion tower, an aqueous alkali solution such as sodium hydroxide may be passed, and the weak acid cation exchange resin in the cation tower may be used. In order to regenerate the resin, an aqueous acid solution such as hydrochloric acid may be passed. The regeneration treatment of the mixed bed tower may be performed by a known method. For example, a saturated saline solution is added to the mixed bed tower, mixed with air, and the specific gravity of the strong basic anion exchange resin and the weak acidic cation exchange resin is separated. Thereafter, after the saturated saline solution is extruded, the acid regenerant is passed through the weakly acidic cation exchange resin and the strongly basic anion exchange resin in a downward flow to regenerate the weakly acidic cation exchange resin. Next, an alkaline regenerant is passed through the strongly basic anion exchange resin layer to regenerate the strongly basic anion exchange resin, and then air mixing may be performed to form a mixed resin layer.

After mixing with air, the specific gravity of the strongly basic anion exchange resin is separated from that of the weakly acidic cation exchange resin. Then, after the saturated saline solution is extruded, 1N-HCl (50 ml) is passed through the weakly acidic cation exchange resin and the strongly basic anion exchange resin in a descending flow manner to regenerate the weakly acidic cation exchange resin. 1N-NaOH (50 ml) was passed through the strongly basic anion exchange resin layer to regenerate the strongly basic anion exchange resin. Thereafter, air mixing was performed to form a mixed resin layer.
This regeneration took 6 hours. If the system is set up under these liquid passing conditions, since the liquid passing time × 2 is longer than the regeneration time of the mixed bed tower, it is possible to set up a system in which another line is regenerated during one line passing. In the apparatus of Example 1,
When a continuous sucrose solution is to be passed, FIG.

し、装置コストを低減することができる。According to the present invention, the sucrose solution is contained in the raw sugar solution by passing it sequentially through an anion column filled with a strongly basic anion exchange resin and a cation column filled with a weakly acidic cation exchange resin. After removing most of the ions,
By passing the solution through a mixed bed tower filled with a mixed resin of a strongly basic anion exchange resin and a weakly acidic cation exchange resin, ions and dyes that could not be removed in the previous stage can be removed. Therefore, while desalinating the sucrose solution and obtaining a high-quality treated sugar solution, the desalting load of the mixed-bed tower is reduced, and the processing time of the mixed-bed tower is increased, thereby making it necessary for the continuous liquid passing process. The number of mixed bed towers can be reduced, and the equipment cost can be reduced.
