(1) Using an automatic control system to control the operation of the extrusion extruder system Adjust the energy input as needed to meet preset operating conditions. Scientifically adjust the pressure and temperature in the extrusion chamber, correctly control the density and ripening degree of the expanded product, and avoid excessive ripening and energy consumption. (2) Correctly adjust and control the air volume and temperature in the dry surface, scientifically use heat exchange equipment to recycle part of the hot air to improve energy efficiency. (3) Keep the material in the dryer to the proper thickness and distribute it as evenly as possible to improve the drying effect and reduce the waste caused by the hot air short circuit. (4) Correctly adjust the air volume and temperature in the control cooler to avoid excessive cooling and improve energy utilization efficiency.
