Industrial Starch Cooking Process

Improving wet end starch for sheet strength, optimizing size press performance, and enhancing coating starch efficiency are a few of the many challenges in starch cooking in paper making.

Through our proven and original Jetcooker™ technology, combined with instantaneous gelatinization of starch, optimized adjustable shear, and precise temperature control, any production issues can become a thing of the past.

Our patented starch cooking solutions use steam to deliver instantaneous heating and consistent cook temperature while effectively providing adjustable shear in any installation. For more information on our advanced direct steam injection technology, click here.

Utilizing Direct Steam Injection in ATTEC® Starch Cooking Systems

Incorporating original Jetcooker™ technology will streamline production flow, increase output, and optimize adjustable shear capabilities.

From starch makedown through cooked starch storage tanks, Hydro-Thermal has the right tools and technology to improve your processing needs. Our ATTEC® starch cooking systems are implemented in over 100 instances all across the country, proving our expertise in industrial starch cooking.
