Starch Gelatinization System for Paper Manufacturing

The paper system performs automated starch paste production with consistent density by using steam to directly heat and gelatinize starch slurry, and then diluting the starch paste liquid.

Fully Automatic Model

Fully Automatic Model

■Advantages

  • The system enables consistent gelatinization at both low and high concentrations regardless of the starch type, including corn and potato starch.
  • The system can accommodate a wide range of load fluctuations and provides a continuous source of starch paste liquid of uniform quality.
  • The system operates reliably with little pressure loss from the Noritake cooker in spite of relatively little steam.
  • When operation is halted, the system automatically washes its internal components with hot water. (self-cleaning feature)
  • Full automation of the system allows for easy operation.
  • The system is compact and requires little installation space.
  • The flow rates for the starch slurry, primary dilution water and secondary dilution water are digitally controlled. In addition, changes to dilution water flow rate can be done in real-time according to changes in starch slurry flow rate through the cascade control function.
  • The system is equipped with a temperature control system that combines a Noritake cooker and its independent mixing functionality with control functions.
  • As an option, the system can be linked with DCS.

■Advantages

  • This model offers excellent cost-performance.
  • Its basic functionality, such as automatic operation and self-cleaning, is based directly on the fully automatic model.
  • Starch slurry flow rate is controlled via the starch slurry pump inverter, and dilution water flow rate is controlled via a self-control valve.
