Q-JET Dual Control Mixing Jet Cookers

Design Benefits of
Q-JET Mixing Jet Cookers

Q-JETMixing Jet Cookers use precisely controlled direct steam injection to pressure cook slurries such as starch, polyvinyl alcohol, and cellulose derivatives.

Q-JET's patented Dual Dynamic Controls - a Linear Valve Stem Actuator and Micrometer-Adjustable Mixing Tube facilitate in-process optimization of steam flow and slurry feed pressure to ensure quiet, hammer-free cooking and high output quality.

At the annulus of the patented Q-JET Micrometer-Adjustable Mixing Tube, slurry combines with steam and accelerates to high velocity.  As the granules pass into the Mixing Tube, they further accelerate, begin to disperse, hydrate and expand.  While passing through the Mixing Tube, the granules undergo high shear mixing, gel, hydrate and exit the Q-JET Mixing Jet Cooker into a retention tube or vessel.

Cooking Temperature
Is Not Equipment Limited

Q-JET's technology applies well to cooking various products, with temperatures controlled to suit the process.  While temperatures typically range from 190° to 325°F, temperature is not equipment limited.
