In the food processing industry, especially for canned products, condiments, or functional beverages in glass jars, "bottle bursting" or "cap jumping" during sterilization is a primary cause of high rejection rates. Unlike pouches or metal cans, the rigidity of glass jars and the integrity of their seals demand strict pressure balance during the sterilization process.

Why Precise Counter Pressure is Critical for Glass Jar Sterilization?

　　During the sterilization process, the internal air and contents expand as temperature rises, causing a rapid increase in internal pressure. If the external pressure within the autoclave cannot counteract this internal pressure in real-time, breakage occurs.

• Thermal Stress Risks: Glass is sensitive to sudden temperature fluctuations.
• Pressure Imbalance During Cooling: During the transition to the cooling stage, if external pressure drops faster than internal pressure, the internal force will instantly blow off the seals.

Technical Advantages of FA-WB150E: Achieving "Zero Breakage"

　　To meet B2B clients' demands for stability, the FA-WB150E provides industrial-grade safety through the following parameterized configurations:

1. Precise Temperature & Pressure Synergy

　　The FA-WB150E operates within a rated pressure range of 0.15–0.2 MPa. Its built-in pressure sensor monitors the internal status in real-time. When a deviation exceeds the threshold, the system automatically introduces compressed air via the air admission valve, ensuring external pressure consistently supports the jar structure.

2. High-Precision $pm0.5^{circ}C$ Temperature Control

　　Uneven heat distribution causes local thermal stress in glass jars. The FA-WB150E offers a temperature setting accuracy of $0.1^{circ}C$ with errors strictly controlled within $pm0.5^{circ}C$. Whether in steam or water bath mode, stable heat penetration minimizes thermal fatigue.

3. Automated Cooling Pressure Compensation

　　After sterilization, the program transitions to the cooling stage. The device introduces water for cooling while maintaining continuous pressure replenishment. This "pressurized cooling" is key to preventing internal pressure overload during temperature drops.
