Jet Cooker for Starch Processing

A starch jet cooker is designed specifically for heating high solids slurries derived from starches, such as potato, wheat, tapioca, rice, and corn. Industrial starch cooking is an important chemical process for:

  • Starch wet milling
  • Grain ethanol production
  • Corn wet milling
  • Fructose production
  • Ethanol production
  • Protein Powder

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. Click here to learn more

How the ProSonix C-Series Jet Cooker Works

The ProSonix C Series starch jet cooker delivers rapid cooking of the starch with precise temperature control. Steam is continuously injected into the flowing starch slurry through an injector coaxial to a starch condensing tube.

Because starch and steam are flowing continuously, there is no plugging or fouling of the heating surfaces to hinder the heating process. Most importantly, the starch slurry is intimately mixed with the steam. This results in rapid and complete starch hydrolyzation and a more complete cookout of the starch.

Starch cook temperatures can be precisely maintained, allowing the process to be fine tuned to the needs of the final starch product. Cook temperatures from 160°F to 300°F (71°C-149°C) are common. Starch can be cooked at dry solids levels up to 40%. This reduces water use and saves energy by reducing evaporative costs.

The steam and slurry are mixed completely which delivers a superior end product as compared to 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.

Jet Cooker Available for Pilot Lab Applications

ProSonix offers a lab scale jet cooker that allows for small scale operation that mimics the performance of the production scale jet cookers.
