Abstract
Disclosed is a method for refining sugar solutions with magnesia wherein magnesia used for refining of a sugar solution is calcined together with pearlite and/or diatomaceous earth at least in an amount of the same weight as that of the magnesia and the resulting calcined mixture is used for refining of the sugar solution again.
Claims2
A method for refining sugar solutions, which comprises refining a sugar solution with magnesia to remove impurities, separating the used magnesia from the sugar solution, calcining the used magnesia together with pearlite and/or diatomaceous earth at least in an amount of the same weight as that of the magnesia, said calcining being at time and temperature sufficient to remove organic substances adsorbed on the magnesia during the refining, while retaining the adsorbing capacity of the magnesia, and using the resulting calcined mixture repeatedly for refining sugar solutions, with said calcining being performed after each refining.
