Screw Cookers and Preheaters
Gentle, efficient cooking for maximum yield and quality
Discover the difference with Fjell's optimized technology
The Fjell Screw Cooker is engineered for fishmeal and fish oil plants and for rendering, delivering gentle, energy-efficient cooking for all types of raw material.
This marketleading screw cooker is an improved and optimised design that builds on the recognised and original Stord-Bartz cooker. Steam and condensate flows are redesigned for more optimal distribution.
With precise control of speed, steam, and temperature, our unique design ensures optimal heat distribution, improved oil yield, and superior product quality.
- Available in single or double-stage versions, and in sizes to fit any facility
- Stainless steel options for maximum hygiene and durability
Key Advantages
- Large heating surface for efficient, even cooking
- Gentle processing improves oil yield and stickwater quality
- Robust, low-maintenance design for long service intervals
- Reduced energy consumption and longer cleaning intervals
- Extremely compact and effective design
For new plants, we recommend our special two stage screw cooker system with improved process control and improved energy efficiency. The standard cooker uses steam as heating medium, but we also design solutions with waste heat recovery and hot water as heating medium.
