The seeds of plants with a high oil or fat content are called oil seeds and can be used for the industrial production of vegetable oil, machine oil or biodiesel. Depending on the region, the main sources of vegetable oils are soybean, rape seed, sunflower seed and palm oil.
Bauermeister offers different types of mills necessary for industrial oil production and press cake exploitation. Bauermeister Roller Mills can effectively pre-crush the cleaned raw seeds while the Bauermeister Flaker introduces a high amount of pressure that leads to the breaking of the oil seed cell walls. These steps are necessary to enable an effective winning of the oil in the oil press that follows. A very popular choice as a Crusher is the VWR250.1 x 1250 while the ZWG800 x 2100 is often sold as the corresponding Flaker, each with an approximate output of 500 t/d.
While the main aim in oil mills is the oil production, many oil seeds contain other valuable ingredients such as fibres and proteins. The press cake from oil production also contains about 10 % of oil which cannot be won by pressing or extraction. While the press cake is often used as animal feed there is a rising interest in exploiting the nutritional value for the human diet. Depending on the intended use different particle sizes are required. They can be produced on Bauermeister Universal Mills or a combination of the mill with a Bauermeister Air Classifier if an even finer product is desired.
Many Bauermeister mills are established all around the world for the flaking of oil seeds or the grinding of oil seed press cake. For every application there is an optimal combination of mill parameters depending on the desired fineness and throughput. The right mill setup and integration of the mill into a production plant depend on the general conditions as well as on the individual requirements of every plant operator. For the evaluation of the criteria Bauermeister specialists are available for a competent consultation.
