    This article presents an automation system of continuous evaporating crystallization based on the DECHAROEN™ technology. The proposed system can be designed in two different ways to support all users' requirements in computerized automation controllers. The first solution is realized based on the use of distributed control system (DCS). The second solution is implemented by using combination of programmable logic controller (PLC) and supervisory control and data acquisition (SCADA). Hardware configurations using SIEMENS PCS7 and using SIEMENS S7-300/WinCC are included to demonstrate the designed concepts. Results of modernized and automated raw sugar boilings using continuous vacuum pans (CVPs) are compared to data of previous processes using batch pans for verifying the effectiveness of the proposed system. Moreover, the proposed automation system is widely accepted by 16 cane sugar manufacturers located in China and Thailand. © 2014 ISSN 2185-2766.
