Completion Ceremony of Large-Scale Candle Filter System for Amino Acid Solution in Xinhecheng Amino Acid Project

The filtration area of a single set of candle filter for this project reaches 115 square meters and above, with significant differences from small-specification equipment in terms of structural design, process design and detailed considerations. Moreover, the customer has extremely high requirements for the operational stability of the equipment. There exist a series of technical challenges in achieving uniform filter cake formation, effective filter cake dewatering, smooth cake discharge and precise control of filter cake moisture content. In this design, we have made special optimizations to the detailed design aspects related to the convenient maintenance and replacement of filter cloths.

These three sets of ultra-large fully automatic candle filters are independently researched, designed and manufactured by Unite, and will be applied to the large-scale amino acid production line of Xinhecheng. In the past, the market for ultra-large candle filters has basically been monopolized by foreign brands, because the use of ultra-large solid-liquid separation equipment in such large-scale production imposes extremely high technical requirements on the equipment. At present, most of the candle filters manufactured in China are of small and medium specifications, as larger candle filters entail more technical challenges. Through continuous R&D, improvement, optimization, and on-site lab scale tests and pilot scale tests, Unite's technical team has broken this foreign monopoly. Wish the Xinhecheng project a successful completion!
