Low energy suction system for food processing retorts
Optimize your sterilization process with innovative suction technology that significantly reduces energy consumption by lowering retort water volumes, cutting heating and cooling costs, and boosting efficiency without compromising on safety or quality.

The Low Energy Suction System (LESS) by JBT FoodTech is an innovative solution designed for static Steam Water Spray (SWS) retorts, significantly reducing retort water volume and associated energy costs. By employing a specialized suction manifold that evenly distributes suction points along the retort’s length, LESS enables processing with a reduced water level, preventing pump cavitation. This technology offers substantial savings, with annual energy cost reductions of approximately $20,800 per retort. It is particularly beneficial for the food industry, enhancing processes such as sterilization, heating, and cooling across a wide range of products, including baby food, dairy, fruit, nuts, oils, and sauces. Adaptable as an upgrade to existing systems or as an option for new installations, this passive system requires no maintenance, ensuring seamless integration into automated batch retort operations.
