Soy protein is a plant-based protein that is derived naturally from soy beans. Soy protein isolate is a kind dry powder food which is highly refined or purified from soybean, with a minimum protein content of 90% on a lower moisture basis. There is a byproduct soy dietary fiber during the process of isolated soy protein. Soy protein powder is a good protein resource, the byproducts soy protein fiber is better solution at regulating or losing weight for human body. Today, we not only focus on the soy protein isolated but also completely utilize the they byproducts soy protein fibers.

The extruded protein fiber was produced with 40% moisture content, 45% soy protein and 15% glycerol. After the further processing, the water is about 16%~18%. In the stage, we could apply microwave drying machine to dehydrate moisture from 16% water content to under 8% with sterilization function. Continuously conveyor belt machine enable to consistently dry soy protein from 200kg/h to 1000kg/h capacity. Microwave thermal and non-thermal function also pasteurize soy protein fiber to achieve the edible purpose in the drying process.

For drying isolated soy protein and soy protein byproducts isolated fiber, you could contact us for more information microwave drying textured soy protein, isolates soy protein powder and soy protein isolated-based fiber.
