How PSX OptiShear Technology Works

Choked flow design delivers sonic velocity steam injection and controls the mass flow of steam through a steam diffuser to ensure rapid mixing and condensation of the steam. This eliminates process upsets and vibration. I-series Inline Jet Diffuser utilizes 360 degree direct steam injection.

Wet Mill Processing of Fructose, Alcohol, Ethanol, and Starch

The ProSonix OptiShear Jet Cooker is designed for starch cooking, wet mill processing of starch, ethanol production, and fructose and 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, through 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 establishing choked flow, the steam mass flow can be metered to precisely control the heating of the liquid. This produces predictable results based on position of the stem plug. Through a variable-area steam diffuser, steam flow is metered at the point where steam and liquid first contact and mix.

Optimize Starch, Steam Mixing, and Reduce Enzyme Use with Adjustable Slurry Gap

In Starch cooking, proper agitation or “shear” is required to optimize the thermal effect of the steam on the starch particles. The OptiShear Jet Cooker is equipped with an adjustable Condensing Tube (CT). The adjustable CT can be positioned to vary the gap relative to the steam nozzle, creating a narrow slurry gap. This narrow gap between the CT and steam nozzle, optimizes the steam exposure to the thin ribbon of starch slurry, as it enters the CT. By changing the position of the CT relative to the face of the steam nozzle, back pressure inside of the OptiShear can be optimized to reduce uncooked starch and enzyme usage.

Industrial Design Drive Assembly for Reliable Starch Slurry Gap Adjustment

Radial Slurry Flow - In the OptiShear design, the condensing tube and steam nozzle interface is truly coaxial, insuring the starch slurry gap is uniform throughout the full 360° flow path. The tube rests on multiple bearing surfaces so there is no movement of the tube relative to the injector except to adjust the gap.

Advanced Drive System - The tube movement in the ProSonix heater to adjust the starch gap is accomplished using a threaded engagement. The tube is rotated and an external thread moves the tube towards or away from the injector (nozzle). Moving the tube in this way changes the orientation of the tube inside the heater, causing any wear spots of the tube to move as well. This has the beneficial effect of evening out the wear of the internal parts and extending their operating life.
