  • Page 4: General Description

    The energy-saving intelligent drying control system SEC-SH can be implemented and modified on most hopper dryers. Remove the original control system of the hopper dryer and replace it with the Shini energy-saving intelligent drying control system, which can save 30%~80% energy consumption according to different blower airflows and environments.

  • Page 5: Coding Principle

    1.1 Coding Principle 1.2 Feature 1) Features microcomputer PID controller, LCD screen. 2) 28 default preprograms material receipt, and simply select materials as required. The system can automatically set the drying and exhaust air temperatures for easy operation. 3) It has a self-adaption function and simply sets the drying temperature; the control system will match the exhaust air temperature.
