Low energy suction system for food processing retorts
Food processors using static Steam Water Spray retorts often face high energy and water costs. Efficiently reducing these costs while maintaining high-quality processing standards is essential.

Reduces retort water volume
The Low Energy Suction System (LESS) by JBT is an innovative technology for static Steam Water Spray (SWS) retorts. It reduces retort water volume by up to 45%, significantly cutting heating and cooling expenses. LESS can be integrated into existing retorts as an upgrade or included in new retorts. The system utilizes a suction manifold that distributes suction points along the vessel’s length, allowing for a low water level during processing without causing pump cavitation. This passive system requires no maintenance and offers substantial annual cost savings of approximately $21,800 per retort.
Benefits
- Significant reduction in energy costs
- Lower water usage in retort process
- Minimal maintenance requirements
- Compatible with existing and new systems
- Substantial annual cost savings
