Process autoclave FL-SJ900×1800

automaticelectronicfor the food industry

Overview
FL-SJ900×1800 is a fully automatic electric water spray retort autoclave for thermal sterilization of retortable packaged foods. It integrates a built-in 60 kW electric heating system with a double-tank water spray circulation to manage controlled heating, holding and cooling phases for products in heat‑resistant pouches or containers.

Key Highlights

• Built-in 60 kW electric heating — no separate steam boiler required.
• Double-tank water circulation for continuous hot water transfer and spray delivery.
• Automatic Siemens PLC temperature and pressure control with touchscreen HMI.
• 304 stainless steel main vessel suitable for food-processing installations.

Advantages / Designed for food processing

• Integrated electric heating removes need for separate steam boiler.
• Automated temperature and pressure control for repeatable sterilization cycles.
• Double-tank water spray enables controlled heating and accelerated cooling stages.
• Food-grade stainless steel construction and hygienic design considerations.

Control system & safety

• Siemens PLC with touchscreen HMI for recipe management and monitoring.
• Continuous pressure and temperature monitoring during cycles.
• Pneumatic valve and actuator control (AirTAC referenced) for reliable operation.
• Safety interlock to prevent opening under pressure and pressure protection devices.
• Recommended routine maintenance: valves, seals, sensors and electrical connections.

Components

• Main vessel: 304 stainless steel with specified wall thickness.
• Electric heating modules: 60 kW total installed.
• Double-tank hot water circulation system with circulation pump (example pump: 3 kW rated).
• Siemens PLC and touchscreen HMI.
• Pressure and temperature sensors and monitoring devices.
• Pneumatic control components for valves and actuators.

Applications

• Meat products and ready meals (sterilized or cook‑and‑chill formats).
• Retort pouches (including stand‑up pouches) when packaging and process are validated.
• Soups, broths and other thermally sterilized packaged foods.

Customer project insight (illustrative)
Example use case: packaged beef bone broth in stand‑up flexible pouches. Project requires validated sterilization schedules, verification of package dimensions and loading patterns, and heat‑penetration testing for the specific product and pouch format.
