Oil mills

Depending on the oil content and the desired quality of the bruised grain, one of the three main state-of-the-art oil separation methods is used: pressing, prepress extraction or direct extraction.

Extracting oils from the various byproducts produced by the cereal processing plant (for example rice bran, wheat germ oil and maize oil) substantially increases the value added by the production. Germ oil is very good for the health on account of the many different active substances it contains, and is becoming an ever more frequent part of diet programs. The pharmaceutical and cosmetic industries also use the positive effects of germ oil in the manufacture of their products.

The right technology and an efficiently designed plant are required to produce select, high-quality wheat and other germ oils for food and cosmetics at internationally competitive prices.

EPC designs oil mills suitable for extracting vegetable oils. They are implemented quickly and easily from a single source. EPC offers plants for receiving, drying and cleaning oilseeds, oil extraction plants using hot or cold pressing or extraction technologies, refining plants, tank farms, as well as the requisite ancillary and supply facilities.



Protein is obtained from the seeds of protein-rich legumes (lupins, peas, broad beans, etc.) as well as from the seeds of typical oil plants (such as soya, rape, sunflowers).

The value added in the processing of oilseeds can be increased by extracting the protein from press cake and extraction meal. For example, soya protein concentrate is used in a wide range of products, such as baby food, dietary products, milk and meat substitute products, confectionery and baking ingredients, as well as in aquaculture fodder.

Converting soya protein concentrate into soya protein isolate by further fractionation creates a niche product for sale in higher price segments. The foodstuffs industry is the main buyer of protein isolates, which it uses, for example, as emulsion and foam stabilizing additives in desserts and drinks.

Promoting the utilization of all the constituents of the plants is both ecologically and economically rational.

EPC offers a range of concepts to meet the extremely diverse requirements of the demanding and ever-growing foodstuffs industry.



The many advantages and positive environmental properties of biodiesel are making it an ever more important fuel. Using non-food oil plants, such as jatropha and algae, avoids a conflict of interests with the foodstuffs industry. Biodiesel can be mixed with conventional diesel without any problems. The quality of the biodiesel produced in plants constructed by EPC meets the fuel standard EN 14214.

Biodiesel is made from vegetable oils, such as rapeseed oil. Cost-effective, efficient logistics and system structures are essential for running a plant profitably.

EPC offers plants for receiving, drying and cleaning oilseeds, oil extraction plants, deacidification and degumming plants, transesterification plants, tank farms, as well as the requisite ancillary and supply facilities.

Downstream plants for converting the glycerine phase – created as a byproduct – into pharmaceutical quality glycerine can be integrated into the plant concepts. The capacities of biodiesel plants are adapted to meet the customers’ requirements. The size of the raw material and final product stores are adjusted to match the regional circumstances.
