In corrugated cardboard manufacturing, starch glue transfer and circulation are critical to ensuring consistent adhesive performance, strong bonding, and efficient production.

Because this industry operates under continuous 24/7 conditions, optimizing starch transfer systems is essential to:

  • Reduce energy consumption
  • Improve adhesive consistency
  • Minimize downtime and maintenance
  • Ensure high-quality board production

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: 

2. Continuous Starch Circulation

  • Glue is continuously circulated between: 
  • Prevents settling, viscosity variation, and film formation

3. Starch Recovery and Reuse

  • Excess glue is collected under the machine
  • A r eturn 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

The Importance of Diaphragm Pumps for Starch Transfer

The Industry Standard for Starch Handling

Diaphragm pumps (AODD & EODD) are ideal for starch transfer because they:

  • Handle viscous fluids
  • Provide low-shear pumping (protects starch)
  • Do not heat adhesives
  • Require no mechanical seals
  • Can run dry
  • Stall safely under pressure
  • Are easy to clean and maintain

Electric vs Air-Operated Diaphragm Pumps

AODD Pumps (Traditional Technology)

• Proven and widely used • Flexible across applications • Good for harsh environments

Limitations:

• High energy consumption • Freezing risk[OS6.1] for most of brands (except ARO) • Plugged mufflers • Glue buildup
