WHAT YOU CAN DO WITH SOY HULLS

Soy hulls are a by-product resulted in soy oil and meal production. But what are the potential ways of further soy hulls reuse? Usually our customers are puzzled with this question especially when this by-product has been accumulated in numbers.

Dry soy hulls contain approximately 85% carbohydrates, 9% protein, 4,3 ash and 1% lipids. The soy cell wall contains about 30% pectin, 50% hemicellulose and 20% cellulose, therefore most soybean carbohydrates fall into the general category of dietary fiber. The outer hull is an excellent source of dietary fiber. Soy fiber contains 38% crude fiber and can have a total dietary fiber content as high as 76%.

So such a by-product as soy hulls could be toasted and ground then blended back into defatted soy meal to make a meal containing 44% protein which automatically becomes a high protein quality livestock feed.

Usually, our customers who deal with soy processing use the mixture of soy hulls, grain components and water, process it in extruders and get the extruded feed component used for livestock.

Also soy hulls are great ingredients for solid fuels production.Soy hulls as a bonding agent helps to produce and environmentally friendly and a perfect fuel to be used in home heating.

Don’t forget about the storage requirements: soy hulls are stored in dry, clean, well-ventilated warehouses or shops with supply-and-exhaust ventilation, protected from direct sunlight, heat sources and humidity.
