Product overview
The FL-WR Double-Tank water immersion & spray retort is engineered for high-temperature sterilization of packaged foods in commercial production lines. The double-tank design allows preheating of process water to reduce cycle time and improve thermal stability. The system operates in full water immersion mode or with controlled hot-water spray, ensuring even heat transfer across various packaging formats including retort pouches, vacuum bags, plastic trays, glass jars, bottles and metal cans. Typical applications: meat, seafood, ready meals, sauces, vegetables and pet food.

Operation and control
The unit is managed by an automatic control system featuring a Siemens PLC and touchscreen HMI. Operators can program temperature profiles, pressure and processing time via the control panel. Automated sequences and interlocks maintain repeatable conditions and reduce manual interventions.
