Industrial starch cooking with a jet cooker is an important chemical process for starch wet milling, grain ethanol production, and other industrial starch processing applications. ProSonix C-Series steam injection Starch Jet Cookers are designed to improve performance over traditional heat exchangers, steam spargers, and steam eductors. Steam mixing valves and steam sparging when done incorrectly can lead to steam hammer, poor starch cook-out, and poor temperature control.
Eliminating these issues can:
- Optimize starch cook-out
- reduce enzyme usage
- reduce steam and energy consumption
- Improve filtration
- Decrease upsets and rework
How It Works
ProSonix’ C-Series Jet Cooker is designed for starch cooking, wet mill processing of starch, ethanol production, and fructose & alcohol production. ProSonix' unique method of direct steam injection utilizes internal steam modulation via an integral Pneumatic Actuator and variable position steam plug, to accurately meter the mass flow of steam at choked flow conditions. Choked flow is the phenomenon of accelerating a vapor to maximum velocity by creating a pressure differential through an engineered opening. By injecting the steam at high velocity we insure thorough, consistent mixing of the starch and steam under all conditions. This produces predictable results regardless of the position of the stem plug.

Advanced Drive System
The tube movement in the ProSonix jet cooker adjusts the starch gap through a threaded engagement. The tube is rotated and an external thread moves the tube towards or away from the steam injector. Moving the tube in this way not only adjusts the starch gap, but also changes the orientation of the tube inside the heater, reducing localized wear and extending part life.
OptiShear CT Auto Drive System
The OptiShearTM is a unique method of automatically controlling the gap the starch slurry passes through between the condensing tube and the steam injector. The OptiShear is operated electrically from the customers control system.
