Definitions

  • the invention relates to a method for pressing a liquid extract from a material to be pressed, in which the material to be pressed is fed to a screw press, transported in the screw press along a pressing path and subjected to a pressing pressure, and in which the screw press is fed with an extractant which, together with the Extract is derived from the pressed material, with carbon dioxide being used as the extraction agent.
  • the invention also relates to a corresponding device.
  • the invention relates to a method and a device for pressing seeds.
  • Seeds such as rapeseed or sunflower seeds are today primarily mechanically pressed to obtain the oil contained in the seeds, and in some cases also obtained by extraction with a solvent such as hexane or supercritical CO2. Oilseeds with a high oil content are usually mechanically pressed because the process is more economical than pure extraction.
  • Screw presses in particular are used for pressing. They enable the seeds to be pressed continuously. The seeds are fed via a feed hopper to the screw press on the input side and transported through the pressing chamber by the rotating screw.
  • the pressing chamber is formed by parallel rods (strainer rods), which are provided with small gaps and are arranged around the screw (strainer basket).
  • the rotation of the auger presses the seed against the inner wall of the auger press and the oil can flow out through the gaps.
  • the compression volume narrows towards the outlet end of the screw, so that when the screw is running, a continuous pressure acts on the mass and oil is pressed out.
  • a largely de-oiled press cake leaves the screw.
  • this largely de-oiled press cake still has an oil content of 10%-15%, and it is also rich in proteins.
  • the press cake is usually processed and used as animal feed, the oil is sold as cooking or industrial oil.
  • there have been various efforts to reduce the residual oil content of the press cake One possibility is to preheat the seeds and press them at temperatures above 100°C (hot pressing). Here the viscosity of the oil is reduced by the increased temperature, more oil can be extracted.
  • the pressing temperatures should be limited to a maximum of 60°C.
  • the density of the carbon dioxide is comparatively low under the conditions of 300-400 bar and 70-90° C. that typically prevail in the screw press; If the temperature in the screw press is reduced, the density of the carbon dioxide used could be significantly increased and thus significantly more CO2 could be dissolved in the oil.
  • WO 2008/116457 A1 discloses a method and a device for pressing, in which the material to be pressed is conveyed by a screw press along a pressing path is transported and subjected to a pressing pressure.
  • the material to be pressed is treated with supercritical carbon dioxide as an extraction agent, which is discharged from the material to be pressed together with the extract.
  • the material to be pressed is transported at a maximum temperature of 60°C along the entire pressing path.
  • the invention is therefore based on the object of specifying a simple possibility for pressing seeds, in particular, which works with a high level of efficiency and requires comparatively little hardware.
  • carbon dioxide is supplied to the screw press in the form of dry ice, which is at least partially transported with the material to be pressed through the screw press along the pressing path, whereby it is sublimated and at least partially compressed to form liquid or supercritical carbon dioxide, and in which the liquid and/or supercritical and/or gaseous carbon dioxide is used as the extraction agent.
  • the effect of carbon dioxide as an extraction agent is therefore based on at least one of several effects.
  • liquid or supercritical carbon dioxide dissolves in the oil, reduces its viscosity and guides it through the openings provided in the screw press, for example through gaps or openings in a strainer basket or strainer rods (here also “extract discharge " called), off.
  • the viscosity of the oil is also reduced by sublimated carbon dioxide gas that dissolves in the oil.
  • the sublimation of the carbon dioxide leads to an increase in volume, which leads to a strong movement of the resulting carbon dioxide gas in the direction of the extract outlet of the screw press, entraining oil with it in a mechanical entrainment effect.
  • the dry ice is thus fed into a feeding unit together with the material to be pressed, fed to the screw press and transported through the screw press along the pressing path.
  • the dry ice sublimes and changes to the liquid or supercritical state in the high-pressure areas of the screw.
  • the liquid or supercritical CO2 dissolves in the extract and moves together with it - driven outwards by the pressure drop - through the extract discharge (e.g. strainer rods) out of the press.
  • CO2 gas also dissolves in the extract, reduces its viscosity and in this way acts as a volume-increasing propellant, which also pushes the extract through the extract outlet to the outside.
  • Any liquid supercritical or gaseous carbon dioxide that is not dissolved in the material to be pressed also exits via the extract discharge line and is discharged.
  • the sublimating dry ice which goes into the liquid or supercritical state, continuously absorbs heat from the pressed material during the pressing process and in this way ensures cooling of the pressed material, which lasts as long as dry ice particles are still present in the pressing path. On the one hand, this happens over at least a large part of the longitudinal extent of the screw press, since the dry ice particles only sublimate gradually. On the other hand, the dry ice particles are also distributed evenly over the cross section by being fed together with the material to be pressed, so that the carbon dioxide is well distributed and can act both as a refrigerant and as an extraction agent.
  • the dry ice is preferably fed to the screw press in the form of carbon dioxide pellets (nuggets) or carbon dioxide snow, which can be easily mixed into the material to be pressed.
  • the carbon dioxide pellets or the carbon dioxide snow are preferably produced from liquid carbon dioxide in a pelleting device or a snow generator on site and fed to a feeding unit of the screw press together with the material to be pressed immediately after their production.
  • the liquid CO2 used to produce the carbon dioxide particles is stored in a tank, for example at a temperature of -20°C and a pressure of 20 bar.
  • the gaseous carbon dioxide produced in the screw press before or during pressing can be removed and put to further use.
  • the gaseous carbon dioxide is used to render the extract inert.
  • carbon dioxide gas that is released during pressing can be fed together with the extract to a collection container, in which it forms an atmosphere that keeps atmospheric oxygen away.
  • a further improvement in quality is achieved in this way, particularly in the case of slightly oxidizing extracts such as edible oils.
  • the temperature in the screw press is measured continuously and the amount of dry ice supplied is regulated so that a predetermined target temperature in the screw press is not exceeded.
  • Material to be pressed and dry ice are preferably fed into the screw press in such a ratio that the temperature in the screw press is kept below a value of 60°C.
  • the amount of pressing material and/or dry ice, which is fed to the screw press is variably adjustable and is controlled as a function of a temperature measured in the screw press, or a proportionate metering of seed and dry ice is installed.
  • the comparatively low temperature of no more than 60°C ensures a particularly low viscosity of the extract and at the same time gentle treatment, especially of pressed goods with temperature-sensitive ingredients such as oilseeds.
  • a device for pressing a liquid extract from a material to be pressed with a screw press which is equipped with a feed unit for feeding in material to be pressed, an extract discharge line for discharging extract separated from the material to be pressed in the screw press, and an outlet line for discharging the material to be pressed that has been at least partially freed from the extract is equipped from the screw press, is characterized according to the invention in that a feed for dry ice, which is operatively connected to a device for producing dry ice, opens into the feed unit.
  • Both the material to be pressed and carbon dioxide in the form of dry ice, in particular dry ice pellets or carbon dioxide snow, are fed into the feeding unit of the screw press. It preferably includes a dosing device, by means of which the quantity flows of product and/or dry ice can be varied.
  • the dry ice particles are expediently produced on site in a commercially available pelleting device, from which the dry ice pellets produced are fed to the dosing device of the feed unit immediately or after intermediate storage in a buffer container.
  • a snow horn can also be used as a device for producing the dry ice, in which liquid carbon dioxide is expanded to form carbon dioxide gas and carbon dioxide snow and the carbon dioxide snow produced is then fed to the dosing device of the feed unit.
  • the task unit Upon contact with the material to be pressed, which may be at ambient temperature, for example, some of the dry ice sublimes into carbon dioxide gas, thereby cooling the material to be pressed.
  • the task unit therefore suitably includes an im essentially gas-tight feed hopper, which is equipped with an exhaust pipe for discharging the resulting carbon dioxide gas.
  • the carbon dioxide gas is discharged into the atmosphere via the exhaust pipe, fed to a further use, such as the pre-cooling of the material to be pressed, or returned to the device for producing dry ice.
  • the rest of the dry ice gets into the screw press with the material to be pressed, where it changes to a liquid or supercritical state during the pressing process and at least partially dissolves in the extract, which reduces the viscosity of the extract and increases the extract yield.
  • the carbon dioxide supplied in the form of dry ice thus becomes the extraction agent that favors the separation of the extract from the rest of the pressed material.
  • a colander screw press is preferably used as the screw press.
  • the screw press is equipped with closed walls in at least one section, for example the front section, through which no extract and no carbon dioxide can escape to the outside; it is also possible to provide several such sections with completely closed walls along the pressing path, which alternate with strainer basket sections through which the extract or carbon dioxide can escape.
  • the closed wall sections serve to ensure that the liquid or supercritical carbon dioxide can act on the material to be pressed and dissolve as well as possible in the extract.
  • the method according to the invention and the device according to the invention are particularly suitable for pressing oilseeds, such as linseed, poppy seeds, rapeseed, soybeans and/or sunflowers; however, the invention is not limited to this application, but can also be used, for example, in applications in environmental technology or the chemical industry.
