通过浓缩重结晶提高杀虫单出粉率生产工艺的探讨

Technique of Production of Raising the Rate of Flour Yield by Concentration and Recrystallization

介绍了将磺化结晶后的母液经薄膜蒸发器蒸发浓缩后进行二次结晶,从而提高出粉率的生产工艺。

This paper introduced the sulfonated crystallized mother liquid was concentrated by film type evaporatorand then crystallize again, thereby raising the rate of flour yield.
