Title:
SUCROSE SOLUTION REFINEMENT METHOD AND REFINEMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/111714
Kind Code:
A1
Abstract:
The present invention refines a sucrose solution by successively passing the sucrose solution through a first column, which is filled with an OH-type strongly basic negative ion exchange resin and an Na-type or K-type positive ion exchange resin, and then a second column, which is provided to a later stage than that of the first column and is filled with a mixture of an OH-type strongly basic negative ion exchange resin and an H-type weakly acidic positive ion exchange resin. By means of the refining method, firstly it is possible to obtain a highly pure sucrose solution, to prevent scaling by suppressing the precipitation of calcium or the like within the device, and furthermore to reduce cost and reduce the amount of sweet water and waste water, and secondly it is possible to reduce the amount of waste water from regeneration liquid when regenerating the refining device.
