Rapid Cooling Strategies Post-Sterilization: Preventing Deformation via Auto-Replenishment

　　The most critical phase of sterilization often occurs during the "cooling period." If pressure transitions are mishandled, packaging undergoes severe secondary deformation. The FA-WB150E autoclave provides an industrial-grade rapid cooling solution.

The Cooling Phase: Root Causes of Packaging Deformation

　　When cooling begins, external pressure falls quickly due to steam condensation. Meanwhile, internal pouch pressure remains high, leading to:

• Physical Squeeze Effect: Pouches burst like balloons.
• Thermal Shock Loss: Glass breakage due to extreme temperature gradients.

FA-WB150E Technical Strategy: Pressurized Cooling

1. Automatic Water Replenishment System

　　The system smoothly injects cold water via the auto-inlet valve. This accelerates heat exchange while providing physical support for flexible packaging.

2. Precise Counter-Pressure Compensation

　　At the instant pressure drops, the control system triggers the air admission valve to introduce compressed air (0.15–0.2 MPa). This "air-maintained pressure" ensures internal autoclave pressure consistently exceeds the internal packaging pressure.

3. Maintenance for Longevity

　　To ensure an 8-year service life, it is recommended to clean scale every three months. Drainage pipes must be steel to handle the immense waste heat energy during discharge.
