7. Yield optimization
There are many stages in the soybean crushing process. Quantity control of a crushing operation requires the existence of a reliable and complete quantity control system in the plant: quantity of beans unloaded, quantity of meal produced and delivered, quantity of oil and lecithin produced and delivered, quantity of hexane put into circuit and hexane losses, quantity of hulls separated...
Weighing plays a vital role in this control. In practice, every stage of production can be the cause of physical product loss.
High levels of foreign matter during cleaning may indicate poor seed quality or dust accumulation in storage silos.
Excessive hexane consumption indicates leaks during distillation or desolvantization, high residual hexane content in cakes or oil, or inadequate wastewater treatment.
