Abstract
A process and a device for obtaining oil from seeds, wherein at least one of the parameters of moisture, fiber content and oil content of the pressed material is continuously measured and evaluated, thus making it possible to continuously control at least one of the following variables: moisture of the pressed material, speed of the press drive and amount of an extraction agent supplied. The oil yield can be increased, the fluctuations in the oil yield can be reduced and energy can be saved by implementing the device-related and process-related features according to the invention.
Claims5
A process for obtaining oil from seeds, comprising steps of:
- supplying a pressed material into at least one conditioner;
- conditioning the pressed material with the conditioner;
- continuously measuring oil content of the pressed material after the conditioning;
- continuously evaluating measurement data with at least one evaluation and control unit;
- continuously controlling an amount of an extracting agent supplied to the pressed material in a pressing chamber of a mechanical pressing unit as a function of the measured oil content of the pressed material;
- conveying the conditioned pressed material to the mechanical pressing unit;
- and
- pressing the pressed material with the mechanical pressing device to separate contained oil from solid components, wherein carbon dioxide is used as the extracting agent.
