[0002] Phthalocyanine blue is a high-grade organic pigment widely used in industries such as inks, paints, plastics, and colorants. Traditionally, the filter cake obtained through filtration is directly dried and ground to produce the finished product. This method can sometimes result in poor product stability. To address this issue, a phthalocyanine blue filter press refluxing production system has been developed. This system improves product stability by adding a refluxing step.

This production reflux device can reduce electricity consumption, the amount of calcium chloride used, reduce pollutant emissions and reduce production costs.
