View SpecificationsFrance stands as one of the agricultural powerhouses of the European Union, with extensive maize cultivation concentrated in regions like Nouvelle-Aquitaine, Occitanie, and the Grand Est. The French starch industry (amidst giants like Roquette and Tereos) demands highly efficient, reliable, and energy-conscious wet milling machinery to process millions of tons of corn annually into starch, sweeteners, bio-ethanol, and animal feed (DDGS).
Modern French biorefineries operate under strict EU environmental regulations and energy efficiency mandates. Consequently, the selection of a degerming mill is critical. The mill must achieve clean separation of the germ from the endosperm without crushing the germ, which would release oil into the starch stream and degrade final product quality. Our advanced degerming mills are engineered to meet these precise requirements, offering adjustable rotor-stator clearances and wear-resistant metallurgy to handle varying maize varieties cultivated across France.
Discuss Your Project RequirementsFrench operators face high electricity tariffs. Our mills optimize motor load and rotor dynamics to reduce specific energy consumption per ton of processed maize.
Our machinery is designed to integrate seamlessly into plants requiring CE marking, ATEX explosion-proof compliance for dust environments, and food-grade hygienic standards.
An in-depth look at the mechanical principles that drive high-yield starch extraction and oil recovery.
In the wet milling process, corn kernels are steeped in a sulfur dioxide and lactic acid solution to soften the gluten matrix. Once steeped, the kernels must be broken open to release the germ without damaging it. This is where the degerming mill plays a pivotal role. Unlike dry milling grinders, a wet degerming mill uses a combination of impact, shearing, and compression forces between a stationary and a rotating disc studded with teeth (rotor and stator).
After passing through the degerming mill, the slurry is directed to germ separators (hydrocyclones) where the lighter, oil-rich germs are separated by density. A clean split in the mill directly translates to a higher purity germ fraction (yielding more corn oil) and a cleaner starch-gluten slurry, reducing the load on subsequent washing and refining stages.

How our degerming mills integrate with downstream concentration and drying systems to maximize plant efficiency.
Maize is steeped to soften the kernel, then fed into the Jiangsu Zongheng Degerming Mill. The mill splits the kernels to release the germ cleanly, preparing the slurry for hydrocyclone separation.
