CLAIMS

What is claimed is:

1. A method for enhancing uniformity of crystallized succinic acid, comprising the steps of: a) preparing a crystallization tank containing therein a jet-flow agitator composed of a rotating shaft and a plurality of inclined converging-tube blades driven by the rotating shaft into rotation;b) pouring a solvent into the crystallization tank of...

DESCRIPTION

BACKGROUND OF THE INVENTION

The present invention relates to a method for producing, and enhancing the uniformity of, crystallized succinic acid. More particularly, the invention relates to a method for dispersing succinic acid crystals homogeneously under a low-rotation-speed and low-power-consumption condition, thereby increasing the yield and purity of the succinic acid product.
