- get soybean kernels
- get soybean hulls
helps to increase protein content of soy feedstock prior to processing
|Moisture of raw material, %:||7-10|
|Hulls residue in the ready product,%:||1,5|
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.
