How Starch Transfer Works in Corrugating
From Glue Kitchen to Application and Recirculation
The starch transfer process begins in the glue kitchen, where adhesive is prepared and sent through a closed-loop system across the corrugator.
Key Process Steps:
1. Starch Glue Transfer
- Starch adhesive is prepared and stored in a buffer tank
- Pumps transfer glue to:
- Singlefacer
- Glue machines
- Local storage near application points:
2. Continuous Starch Circulation
- Glue is continuously circulated between:
- Buffer tank → glue pans → return loop
- Prevents settling, viscosity variation, and film formation
3. Starch Recovery and Reuse
- Excess glue is collected under the machine
- A recirculation pump, also called return pump, transfers it back to storage
- Adhesive is recirculated and reused
This full loop is essential for maintaining consistent starch quality and minimizing waste
