De Hullers

The dried to 8-9% soy is fed into twin roll mill. Soybeans are compressed between the first pair of rolls. As a result shell bursts and kernel breaks up into several parts. Soy mixture falls into the second pair of rollers. The milling process is repeated. A high protein mixture of soy kernel and hull moves to the feeding system and air separator MA-4. Soybean shells have a light specific weight that’s why air flow moves husks up and outputs them through the cyclone. Soybean hulls have a great amount of fiber while kernels are rich protein. Process of dehulling increases mass fraction of soy protein.
