Steam water spray retort for shelf-stable food processing
In the production of shelf-stable foods such as ready meals, pet food, and sauces, precise and uniform sterilization is essential to ensure safety and longevity. Achieving consistent temperature distribution and minimizing water usage during cooling can be challenging with traditional methods.

Achieve uniform temperature distribution and efficient cooling.
The Static Retort – Steam Water Spray™ (SWS) by JBT offers a solution to these challenges. With direct steam injection at the bottom and water sprays along the shell length, the system achieves fast and uniform temperature distribution. This ensures consistent sterilization across different types of containers, including rigid, semi-rigid, and flexible. The use of a plate heat exchanger for indirect, sterile cooling reduces water consumption and eliminates the need for chemical treatments. The system’s design allows for precise control of temperature and pressure, making it ideal for industries such as fruits and nuts, juices and beverages, oils, soups, sauces, pet food, and pharmaceuticals.
