Automated Digester Level Control System
Product Description:
Fruitlet digestion plays an important role in increasing the Oil Extraction Rate(OER). Dolphin's Automated Digester Level Control System, determines the feed rate of fruitlets into the digester chamber by precisely weighing the digestion mass using load cells. When the digestion mass weight reaches high level, the hydraulically operated feed door is automatically closed and the discharged chute to the press opened to allow the discharge of the digested mass to the press.

The primary purpose of the system is to ensure proper fruit digestion and constant fruit feeding to screw press machine.
Digester Levelling Control
Fruit capacity in the digester is controlled and maintained at a preset value to ensure sufficient digestion time.
Centralise Control of Fruit Distribution
The system monitors and controls fruit capacity in all digesters. Distribution loose fruit equally into digesters is automatically controlled to ensure even fruit capacity in all digesters and to maximise fruit digestion within the allocated time.
Interactive Human Machine Interface(HMI) Device
DISS is equipped with interactive touch screen HMI for configuring anf setting of operation and reporting parameters.
Historical Reporting System
DISS includes a historical reporting function for production monitoring. The historical report provides details operation settings, user login record, operating ampere historigram, and motor tripping recording.
Multi Level User Access
The system is designed for multi level user access and password protection to prevent unauthorized system access. The system provides for two(2) levels of user access, namely; Administration/Engineer, and Operations authorised personnel.
Redundancy system
The digester control system is integrated with redundancy system override to provide for switching to manual operation as a backup system in the event of electronic malfunction. This further underwirtes the reliability and uptime of the system.
  Maximises oil recovery
  Minimises labour dependency to monitor and maintain optimum digester operation parameters.
  Ensures optimum thoughput and synchronised passage of material from the tipper, to the SFB conveyor, water dilution and depericarper processes.
