Corn Germ Dewatering Screw Press
In the corn wet milling and starch processing industry, corn germ dewatering is a critical step that directly impacts downstream efficiency and product quality. The Dewatering Screw Press plays an essential role by reducing moisture content with precision while preserving the delicate structure of the germ — a key component in oil extraction.
Why Corn Germ Requires Specialized Dewatering
Corn germ, once separated during the milling process, contains up to 90% moisture and is highly sensitive due to its oil-rich and soft cellular structure. Aggressive or uncontrolled dewatering can rupture oil cells, leading to losses and degraded product quality.
To ensure proper handling, the corn germ is first passed through side hill (parabolic) screens for preliminary removal of free water. The semi-wet germ is then processed through our specially designed Dewatering Screw Press, which applies a gradual, low-shear pressure to gently reduce moisture to around 50–55%.
The Critical Role of the Screw Press
The screw press is not just a moisture removal device — it is a key enabler of efficient and sustainable processing. Its ability to mechanically reduce water content without damaging the germ offers several crucial benefits:
