A food company in Spain needed a high temperature sterilizer for beef bone broth in stand-up Doypack pouches. Foodmax Machines recommended a 1000L fully automatic double-layer water spray retort autoclave with electric heating.
The firm planned beef bone broth for packaged foods. Steps included bone processing, secondary cooking, fat separation, concentration, filling, and high-temperature sterilization. The client’s needs shaped the choice of high temperature sterilizer:
Fit for flexible Doypack pouches
1000L nominal capacity
Practical delivery schedule
Digital temperature and pressure control supported process monitoring. The goal was longer room-temperature shelf life. Final results depend on formula, pouch specs, filling, and a validated thermal process.
Foodmax Machines selected one FL-SJ900×1800 fully automatic double-layer water spray retort autoclave. This autoclave machine for sterilization uses electric heating and 304 stainless steel construction. The double-layer design pairs a retort vessel with a hot water tank. Hot water is sprayed over the packages for controlled heating and cooling. Final operating parameters and the sterilization schedule must be confirmed against the actual product, pouch specifications, and process validation requirements.

Our HighTemperatureSterilizer SafetyFeatures and Advantages
Overpressure and vacuum protection: Triple mechanical safety valves and a manual emergency vent guard against overpressure. A negative pressure relief device prevents vessel collapse.
Reliable temperature monitoring: Two temperature sensors compare readings during sterilization. The system sounds an alarm and pauses when temperature or pressure deviates.
Stable pressure and simple operation: A pressure stabilizing system limits the temperature impact of air injection. The PLC touchscreen stores sterilization curves.
Durable construction: The 304 stainless steel body has hot-spun heads and aluminum silicate insulation. The silicone door seal withstands 200 °C.
Safer door design: The one-piece forged door flange has no welds. A triple safety interlock and a vacuum-return seal make the door easy and safe to operate.

Pressure Cooking Kettle vs. Retort Autoclave
During technical discussions, the customer asked whether a pressure cooking kettle could handle sterilization. We explained that the two machines serve different purposes. A pressure cooking kettle supports cooking or pressure-based extraction, depending on its design. A retort autoclave is a heat sterilizer machine for packaged products under controlled temperature and pressure. The two should not be treated as interchangeable.
We also reviewed the full production sequence: cooking, fat separation, concentration, filling, and retort processing. The high temperature autoclave sits at the end of this line, after filling. The project uses a dedicated water spray retort for final sterilization.
