Hydrothermic Treatment of Wheat Flour

Heat treated wheat flour is very suitable for producing savoury foods such as natural sauces, soups and gravies. Functional characteristics such as heat, acid and shear stability are essential when preparing thermally processed or dry mix foods. The process requires controlled conditions like precise moisture addition, short residence time during drying and direct and indirect heat input. Hosokawa Micron provides a very suitable solution for the thermal treatment of wheat flour, combining its Nauta® conical screw mixer and the Drymeister (DMR-H) flash dryer.

First, wheat flour is loaded in the Nauta mixer, provided with a heating jacket. There it is mixed with steam and cooked for an adjustable period of 20-40 minutes. After the cooking cycle, the mixer is quickly unloaded into an intermediate jacketed hopper. From there the product is fed directly into the Drymeister (DMR-H) where it is milled and dried within a few seconds, resulting into a dry powder.
