Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Speiseöl aus Rapssaat oder anderen Ölsaaten, wobei die Rapssaat o. dgl. nach dem Durchlaufen eines Klassierdecks zunächst getrocknet, gebrochen und gesichtet wird und schließlich nach einer Aufbereitung einer Presse zugeführt wird. Die Erfindung betrifft ferner eine Einrichtung für die Durchführung des Verfahrens. Zur Vereinfachung ist im Folgenden nur auf Rapssaat Bezug genommen.The invention relates to a method for producing Edible oil from rapeseed or other oil seeds, the Rapeseed or the like after passing through a classifying deck is first dried, broken and sifted and finally after preparing a press is fed. The invention further relates to a Establishment for the implementation of the procedure. For In the following, simplification is only related to rapeseed taken.
Bei den bekannten Verfahren zur Herstellung von Speiseöl wird die Rapssaat ohne vorherige Schälung verarbeitet, obwohl die Rapsschälung betreffende Verfahren bekannt sind (DE-PS 21 35 173, DD-PS 131 530, DE-OS 40 41 994).In the known processes for the production of cooking oil the rapeseed is processed without prior peeling, although rape peeling is known are (DE-PS 21 35 173, DD-PS 131 530, DE-OS 40 41 994).
Eine der genannten Literaturstellen (DE-PS 21 35 173) betrifft ein Verfahren zum Schälen körniger Ölfrüchte, bei dem die Körner einer Prallwirkung unterworfen werden. Hierbei werden die in einem kurzen Zeitintervall auf etwa 45 °C erwärmten Körner mittels eines Kaltluftstroms gegen schräg zur Strömungsrichtung verlaufende Prallplatten geschleudert. Die dabei aufgebrochenen Körner werden dann mechanisch durch Reibung ohne Ölextraktion von der Schale getrennt, indem die mit dem Luftstrom vermengten Körner einer schraubenlinienförmigen Bewegung zwischen Reibungswänden unterworfen werden.One of the cited references (DE-PS 21 35 173) relates to a process for peeling granular oil fruits, in which the grains are subjected to an impact become. This is done in a short time interval Grains heated to about 45 ° C using a stream of cold air against diagonally to the flow direction Impact plates thrown. The broken up Grains are then made mechanically by friction without oil extraction separated from the shell by the one with the Airflow blended grains of a helical shape Be subjected to movement between friction walls.
Die zweitgenannte Literaturstelle (DD-PS 131 530) betrifft ein Verfahren zur Enthüllung von öl- und proteinhaltigen Saatkörnern, wobei die Hülle durch eine Verformung der Saatkörner vom Kernfleisch gelöst und anschließend Hülle und Kernfleisch voneinander getrennt werden. Zum Lösen der Hülle vom Kernfleisch werden die Saatkörner einer definierten Verformung zwischen zwei starren Flächen ausgesetzt, wodurch die Hülle abplatzt. In einem nachfolgenden Sichtvorgang erfolgt dann die Trennung der Hülle vom Kernfleisch.The second cited reference (DD-PS 131 530) relates to a process for the disclosure of oil and proteinaceous seeds, the casing by a Deformation of the seeds released from the core meat and then shell and core meat separated become. To remove the shell from the core meat, the Seeds of a defined deformation between two exposed to rigid surfaces, causing the shell to flake off. This then takes place in a subsequent viewing process Separation of the casing from the core meat.
Die weitere genannte Literaturstelle (DE-OS 40 41 994) betrifft ein Verfahren und eine Anordnung zur Rapsschälung, das die Gewinnung von Kernfraktionen mit Schalenanteilen < 5%, wie sie für die Nutzung des später gewonnenen Öles für Kraftstoffzwecke oder auch für andere technische Zwecke benötigt werden, ermöglicht. Dies wird durch eine kombinierte Druck- und Schlagbehandlung des Saatgutes herbeigeführt. Die gewonnene Kernfraktion kann hierbei direkt den für die Treibstoffgewinnung folgenden Prozessen zugeführt werden. Das bekannte Verfahren sieht u. a. vor, daß die gereinigte Rapssaat heiß - bei einer Temperatur von 95°C - getrocknet und anschließend durch einstufige Walzung geschält wird, wobei der Walzenspalt dem 0,2-fachen bis 0,4-fachen des mittleren Saatkorndurchmessers entspricht. Das Lösen der aufgebrochenen Schalen vom Kernfleisch erfolgt durch Schlagprallösen bei einer pneumatischen Förderung, gegebenenfalls durch eine Windsichtung und eine Trennung der Schalen vom Kernfleisch durch Elektroseparation. Die technologische Anordnung zur Rapsschälung besteht aus einem Saatbunker, einer Waage, einem Walzenschäler, einem Zyklon, einem Windsichter und einem Elektroscheider. Dieses bekannte Verfahren hat technologisch erhebliche Nachteile. Die heiße Trocknung der Saat führt zu den bekannten Qualitätsnachteilen der aus thermisch beanspruchtem Material gewonnenen Rohöle. Die einmalige Walzung zur Zerlegung der Saat mit einem breiten Kornspektrum bei einem Walzenspalt von 0,45 mm führt zur Zerquetschung der Saat und damit zum Ölaustritt, wodurch die Zerlegung des Gemisches im nachfolgenden Sichtprozeß erschwert wird. Deshalb erfordert das bekannte Verfahren eine zusätzliche pneumatisch Förderung mit Lösen durch Schlagprall und eine zusätzliche, energetisch ungünstige Windsichtung zur Abtrennung ungeschälter Saatkörner, bevor die eigentliche Trennung des Gemisches auf dem Elektrosichter erfolgt.The other cited reference (DE-OS 40 41 994) relates to a method and an arrangement for rape peeling, that with the extraction of core fractions Shell proportions <5% as required for later use won oils for fuel purposes or also for other technical purposes are required. This is done through a combined pressure and impact treatment of the seeds. The won The core fraction can directly be used for fuel production following processes. The known method sees u. a. before that cleaned Rapeseed hot - at a temperature of 95 ° C - dried and then by single-stage rolling is peeled, the nip 0.2 times to Corresponds to 0.4 times the average seed grain diameter. Detaching the broken shells from the Core meat is made by impact impact loops at one pneumatic conveying, if necessary by a Air separation and a separation of the shells from the core meat through electrical separation. The technological The rape peeling arrangement consists of a seed bunker, a scale, a roller peeler, a cyclone, one Air classifier and an electric separator. This well known The process has significant disadvantages in terms of technology. The hot drying of the seeds leads to the known quality disadvantages that of thermally stressed material extracted crude oils. The one-time rolling for disassembly the seed with a wide grain spectrum in one Roller gap of 0.45 mm leads to crushing of the seeds and thus to oil leakage, whereby the disassembly of the Mixtures in the subsequent visual process is made more difficult. The known method therefore requires an additional one pneumatic conveyance with loosening by impact impact and an additional, energetically unfavorable wind sifting for separating unpeeled seeds before the actual separation of the mixture on the electric classifier he follows.
Die Rapsschälung hat in der Praxis keine Bedeutung erlangt. Vielmehr wird in aller Regel bei der Herstellung von Speiseöl die Rapssaat zunächst gequetscht und dann ausgepreßt. Dabei gelangen durch den hohen Schalengehalt verhältnismäßig viele Wachse und andere Inhaltsstoffe in das Speiseöl, das dadurch nur eine geringe Qualität aufweist. Die bekannten Verfahren zur Herstellung von Speiseöl aus Ölsaaten benötigen daher zur Reinigung der Öle eine chemische und physikalische Raffination.Rapeseed peeling has gained no importance in practice. Rather, it is usually used in manufacturing of edible oil the rapeseed is squeezed first and then squeezed out. Here pass through the high shell content relatively many waxes and other ingredients into the cooking oil, which is only a small Quality. The known methods of manufacture of cooking oil from oilseeds therefore need Cleaning the oils a chemical and physical Refining.
Es hat nicht an Versuchen gefehlt, die bei der Verarbeitung ungeschälter Rapssaat auf Seiher-Schneckenpressen infolge der durch die Schalen verursachten hohen Reibung zwangsläufig entstehenden Preßtemperaturen von deutlich oberhalb 40 °C zu senken. So wurde eine Schneckenpresse mit aufwendiger Kühlung eines Ringseiherkorbes vorgeschlagen (DE 41 09 229 C2). Die kontinuierliche Kühlung der umgebenden Preßgeometrie soll die hohe Reibungswärme während des Preßvorgangs abführen, um niedrige Preßtemperaturen unterhalb von 38 °C zu erreichen. There has been no shortage of attempts at processing unpeeled rapeseed on colander screw presses due to the high caused by the shells Friction inevitably occurring press temperatures of lower significantly above 40 ° C. So one became Screw press with complex cooling of a ring strainer basket proposed (DE 41 09 229 C2). The continuous Cooling of the surrounding press geometry is said to dissipate high frictional heat during the pressing process, to low press temperatures below 38 ° C to reach.
Zur Ausbeutesteigerung arbeitet die konventionelle Rapssaatverarbeitung in Anlagen mit größerer Verarbeitungskapazität mit einer hydro-thermischen Behandlung der Saat vor dem Pressen. Die dabei üblichen Konditionierungstemperaturen von bis zu 100 °C verstärken noch die nachteiligen Einflüsse der hohen Preßtemperaturen. Die Gehalte an freien Fettsäuren und Phosphatiden im Preßöl sind gegenüber nicht vorgewärmter Saat weiter erhöht.Conventional rapeseed processing works to increase yield in plants with larger processing capacity with a hydro-thermal treatment of the Sowing before pressing. The usual conditioning temperatures of up to 100 ° C increase the adverse influences of the high press temperatures. The Contents of free fatty acids and phosphatides in the press oil are further increased compared to non-preheated seeds.
Durch die Pressung der ganzen Rapssaat mit Schalen gelangen hüllenspezifische Inhaltsstoffe, wie Chlorophyll, Wachse, freie Fettsäuren und Tannine (Bitterstoffe) in das Rohöl, wodurch die Qualität des Rohöls über den negativen Einfluß hoher Preßtemperaturen hinausgehend zusätzlich negativ beeinflußt wird. Chlorophyll und seine Abbauprodukte wirken als Prooxidantien; sie vermindern die Haltbarkeit und beeinträchtigen die sensorische Qualität des Öls. Die Tannine verschlechtern die Sensorik und geben dem Öl einen bitteren grasigen Geschmack. Die auch durch Raffination nicht entfernbaren Wachse der Schalen verbleiben im Öl und wirken als Kristallisationskeime bei kühler Lagerung.By pressing the whole rapeseed with husks shell-specific ingredients such as chlorophyll, Waxes, free fatty acids and tannins (bitter substances) in the crude oil, thereby reducing the quality of the crude oil about the negative influence of high press temperatures is also negatively influenced. Chlorophyll and its breakdown products act as prooxidants; they reduce the durability and impair the sensory quality of the oil. The tannins deteriorate the sensors and give the oil a bitter grassy Taste. Those that cannot be removed even by refining Waxes of the shells remain in the oil and act as Crystallization nuclei in cool storage.
Die hohen Gehalte an unerwünschten Inhaltsstoffen bei der konventionellen Verarbeitung ganzer Rapssaat mit Schalen müssen nachträglich aus den Rohölen entfernt werden. Die aus nicht vorgewärmter Saat gepreßten Öle werden zur Verbesserung der Sensorik und Haltbarkeit häufig einer Dämpfung bei Temperaturen oberhalb 100 °C unterzogen. Die aus konditionierter Saat gepreßten Öle müssen einer Raffination mit Temperaturen > 200 °C unterzogen werden. Die hohen Temperaturen der Dämpfung und Raffination führen zur Bildung von ernährungsphysiologisch negativen Transfettsäuren und zur Minderung der Gehalte an leichtflüchtigen wertvollen Vitaminen. The high levels of unwanted ingredients conventional processing of whole rapeseed Shells have to be removed from the crude oils become. The oils pressed from not preheated seeds are used to improve sensor technology and durability often damping at temperatures above 100 ° C subjected. The oils pressed from conditioned seeds must be refined at temperatures> 200 ° C become. The high temperatures of damping and Refining lead to the formation of nutritionally negative trans fatty acids and to reduce the Contains volatile, valuable vitamins.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Einrichtung zu schaffen, um kaltgepreßtes Speiseöl herzustellen, das unter Vermeidung einer das Öl thermisch belastenden und energetisch aufwendigen Raffination bzw. Dämpfung unmittelbar als hochwertiges Speiseöl verwendet werden kann.The invention has for its object a method and to create a facility to cold-press Make cooking oil while avoiding the oil thermally stressful and energetically complex Refining or damping immediately as high quality Cooking oil can be used.
Die Lösung der gestellten Aufgabe besteht bei einem Verfahren der eingangs genannten Art darin,
- daß die Rapssaat mittels einer Siebmaschine in drei Fraktionen verschiedener Partikelgrößen getrennt wird, und zwar in Besatz, in gereinigte Rapssaat und in Kümmerkorn,
- daß die gereinigte und klassierte Rapssaat anschließend bei einer Trocknungstemperatur unterhalb einer Grenztemperatur von 40 °C auf einen Wassergehalt des ganzen Rapskorns von 4,5 % bis 5,5 % getrocknet wird und der Besatz und das Kümmerkorn einem Silo zugeführt werden,
- daß danach die getrocknete Rapssaat in einem Walzwerk gebrochen wird,
- daß dann die gebrochene Rapssaat - der Rapsbruch - durch Klassieren in drei Fraktionen verschiedener Partikelgröße getrennt wird, und zwar in Anbruch, in Nutzbruch und in Feinbruch,
- daß der Nutzbruch in einem Sichter in Schälraps und Schalen zerlegt und der Anbruch sowie der Feinbruch dem Silo zugeführt werden,
- daß sodann der Schälraps befeuchtet und anschließend in einem weiteren Walzwerk - einem Flockierwalzwerk - flockiert wird,
- daß danach der flockierte Schälraps in einer Presse kalt verpreßt wird
- und daß schließlich durch Reinigung des aus der Presse austretenden Preßöls von Trubstoffen (Feststoffen) Speiseöl gebildet wird.
- that the rapeseed is separated into three fractions of different particle sizes by means of a sieving machine, namely in stocking, in cleaned rapeseed and in grain
- that the cleaned and classified rapeseed is then dried at a drying temperature below a limit temperature of 40 ° C. to a water content of the whole rapeseed grain of 4.5% to 5.5% and the trimmings and the grain of the grain are fed to a silo,
- that the dried rapeseed is then broken up in a rolling mill,
- that the broken rapeseed - the rapeseed - is then separated into three fractions of different particle sizes, namely in the first part, in the useful part and in the fine part,
- that the useful break is broken down into peel rape and shells in a sifter and the opening and the fine break are fed to the silo,
- that the peeling rape is then moistened and then flaked in another rolling mill - a flaking mill,
- that the flaked rape is then cold pressed in a press
- and that, finally, edible oil is formed by cleaning the press oil emerging from the press from turbid substances (solids).
Hierbei setzt sich der Besatz aus Fremdsaaten, Pflanzenteilen und diversen Verunreinigungen, die gereinigte Rapssaat aus ganzen Rapskörnern und einem geringen Anteil an Pflanzenteilen und das Kümmerkorn aus verkümmerten oder angebrochenen Rapskörnern, Planzenteilen und Feinstaub zusammen.Here the stocking consists of foreign seeds, plant parts and various contaminants, the cleaned Rapeseed from whole rapeseed and a small one Proportion of plant parts and the caraway grain from stunted or cracked rapeseed, parts of plants and Fine dust together.
Es kann zweckmäßig sein, die Rapssaat vor dem Klassieren durch einen Metallabscheider zu führen.It may be useful to rapeseed before classifying through a metal separator.
Das mittels des erfindungsgemäßen Verfahrens gewonnene Speiseöl weist nur noch äußerst geringe Gehalte an unerwünschten Inhaltsstoffen auf. Es handelt sich daher um Speiseöl besonders hoher Qualität. Eine anschließende Nachbehandlung durch Raffination oder Dämpfung ist nicht erforderlich. Bei dem gewonnenen Speiseöl, das einen sensorisch positiv zu bewertenden feinnussigen Eigengeschmack aufweist, bleiben die hohen Gehalte an den leichtflüchtigen Vitaminen erhalten. Erreicht wird dies durch die Entfernung des überwiegenden Teils der Rapsschalen und durch die niedrigen Preßtemperaturen. Nach dem gegenwärtigen Stand des Wissens kann davon ausgegangen werden, daß für Preßöle, die aus der Presse mit einer Grenztemperatur unterhalb 40 °C ablaufen, keine die Qualität schädigenden Vorgänge zu erwarten sind. Bei Pressung der schalenreduzierten Saat ohne weitere Vorbehandlung kann aufgrund der Erwärmung infolge intensiver Reibung in der Seiher-Schneckenpresse die genannte Grenztemperatur noch nicht unterschritten werden. The obtained by means of the method according to the invention Cooking oil only shows extremely low levels unwanted ingredients. It is therefore high-quality cooking oil. A subsequent one Post-treatment by refining or steaming is not required. With the cooking oil obtained, one fine nutty own taste to be evaluated positively the high levels of the get volatile vitamins. This is achieved by removing the majority of the rape shells and due to the low pressing temperatures. To the current state of knowledge can be assumed be that for press oils that come from the press with a limit temperature below 40 ° C, none quality-damaging processes are to be expected. At Pressing the reduced-seed seed without further pretreatment may be more intense due to warming Friction in the colander screw press the mentioned Limit temperature must not be fallen below.
Durch die niedrige Trocknungstemperatur unterhalb der Grenztemperatur von 40 °C wird eine qualitätsmindernde Enzymaktivierung ausgeschlossen und durch das enge Spektrum im Wassergehalt von 4,5 % bis 5,5 % wird eine vereinfachte Saatschälung ermöglicht.Due to the low drying temperature below the Limit temperature of 40 ° C will reduce quality Enzyme activation excluded and by the close A spectrum in the water content of 4.5% to 5.5% becomes a Simplified seed peeling enables.
Es hat sich als vorteilhaft erwiesen, daß die Trennung der Rapssaat in drei Fraktionen in der Weise erfolgt, daß die Partikelgröße des Besatzes mehr als das 1,1-fache, die Partikelgröße der gereinigten Rapssaat zwischen dem 0,7-fachen und dem 1,1-fachen und die Partikelgröße des Kümmerskorns weniger als das 0,7-fache des mittleren Rapskorn-Durchmessers beträgt.It has proven advantageous that the separation rapeseed is divided into three fractions in such a way that the particle size of the fill is more than 1.1 times, the particle size of the cleaned rapeseed between 0.7 times and 1.1 times and the Particle size of the kernel grain is less than 0.7 times of the average rapeseed grain diameter.
Zweckmäßigerweise beträgt die Trocknungstemperatur der gereinigten und klassierten Rapssaat maximal 35 °C. Diese Maßnahme trägt sehr wesentlich dazu bei, eine Schädigung der Fettsäuren, Denaturierung der Proteine und Aktivierung der Saatenzyme zu verhindern.The drying temperature is expediently the cleaned and classified rapeseed maximum 35 ° C. This measure contributes significantly to a Damage to fatty acids, denaturation of proteins and prevent activation of the seed enzymes.
In Ausgestaltung der Erfindung erfolgt das Brechen der gereinigten und getrockneten Rapssaat in zwei konsekutiven Walzvorgängen, und zwar erfolgt zunächst ein Vorbrechen und danach ein Nachbrechen, jeweils in einem Walzwerk mit Glattwalzen, wobei die mittlere Spaltweite des Walzenspaltes bei der Vorbrechung größer als bei der Nachbrechung eingestellt wird. Zweckmäßigerweise wird die mittlere Spaltweite des Walzenspaltes bei der Vorbrechung die mittlere Spaltweite des Walzenspaltes bei der Vorbrechung auf das 0,4-fache bis 0,5-fache und bei der Nachbrechung auf das 0,3-fache bis 0,4-fache des mittleren Rapskorn-Durchmessers eingestellt.In an embodiment of the invention, the breaking of the cleaned and dried rapeseed in two consecutive Rolling operations, and that takes place first Prebreak and then post-break, each in one Rolling mill with smooth rolls, the mean gap width of the nip is larger in the preliminary break than in the Postbreak is set. Expediently the mean gap width of the roll gap during the preliminary break the mean gap width of the roll gap at the pre-break to 0.4 times to 0.5 times and at the refraction to 0.3 times to 0.4 times the medium rapeseed diameter set.
Durch die realisierte Doppelbeanspruchung bei vermindertem Walzenspalt wird die Ablösung von Schalen und Kernfleisch mit einem hohen Grad der Saatzerlegung bereits während des Brechens erreicht. Durch die definierte Verformung der Saatkörner wird erreicht, daß die Schale abplatzt, ohne daß das Kernfleisch zerquetscht wird. Der Rapskern zerfällt lediglich in seine natürlichen fünf Elemente, wie je zwei äußere und innere Keimblätter sowie den Keimling, weil die Elemente nur in einem eng lokalisierten Bereich untereinander verbunden sind. Ein wesentlicher Ölaustritt aus den Rapskern-Elementen wird dadurch vermieden.Due to the realized double load with reduced Nip will be the peeling of shells and Core meat with a high degree of seed laying already reached during breaking. By the defined Deformation of the seeds is achieved that the Peel peels off without crushing the core meat becomes. The rapeseed core only disintegrates into its natural five elements, like two outer and two inner Cotyledons as well as the seedling because the elements are only in in a closely localized area are. An essential oil leak from the rapeseed elements is avoided.
Es hat sich ferner als vorteilhaft erwiesen, daß die Trennung des Rapsbruches in drei Fraktionen in der Weise erfolgt, daß die Partikelgröße des Anbruchs mehr als das 0,7-fache, die Partikelgröße des Nutzbruchs zwischen dem 0,2-fachen und dem 0,7-fachen und die Partikelgröße des Feinbruchs weniger als das 0,2-fache des mittleren Rapskorn-Durchmessers beträgt.It has also proven advantageous that the Separation of the rapeseed into three fractions in this way that the particle size of the crack is more than that 0.7 times the particle size of the usable fraction between the 0.2 times and 0.7 times and the particle size of the Fine fraction less than 0.2 times the average Rapeseed grain diameter.
Um das Abpressen des Schälrapses mit geringem Schalengehalt auf Schneckenpressen bei niedrigen Temperaturen zu ermöglichen, erfolgt die Konditionierung des Schälrapses durch eine Befeuchtung bei einer Temperatur unter 40 °C, wobei ein Wassergehalt von 5 % bis 7 %, vorzugsweise von 5,5 % bis 6,5 % eingestellt wird. Durch die Entfernung der Rapsschalen mit hohem Wassergehalt hatte sich der Wassergehalt des Schälrapses gegenüber der gesamten Saat zuvor um ca. 1 % erniedrigt.The pressing of the peeled rape with a low shell content on screw presses at low temperatures To enable the peeling rape to be conditioned by humidifying at a temperature below 40 ° C, with a water content of 5% to 7%, preferably is set from 5.5% to 6.5%. Through the Had removal of the rape pods with high water content the water content of the peeled rape compared to the entire seeds previously reduced by approx. 1%.
Es hat sich als besonders vorteilhaft erwiesen, daß die Konditionierung des Schälrapses bei einer Temperatur von maximal 35 °C erfolgt.It has proven to be particularly advantageous that the Conditioning the peel rape at a temperature of maximum 35 ° C.
In weiterer Ausgestaltung der Erfindung wird der befeuchtete Schälraps auf einem Flockierwalzwerk mit Glattwalzen und einem Schlupf von ca. 5 % aufgeschlossen. Durch den gemäß der Erfindung eingestellten Wassergehalt wird das Kernfleisch soweit plastifiziert, daß Feinbruch vermieden und ein hoher Aufschlußgrad, also ein hoher Anteil an mechanisch geöffneten Zellen erreicht wird.In a further embodiment of the invention moistened peeled rape on a flaking mill Smooth rolling and a slip of approx. 5% open. By the set according to the invention The core meat is plasticized to the extent that that fine breakage is avoided and a high degree of disintegration, so a high proportion of mechanically opened cells is achieved.
Bei der Flockierung des Schälrapses wird zweckmäßigerweise der Walzenspalt der Glattwalzen des Flockierwalzwerks derart eingestellt, daß die mittlere Spaltweite des Walzenspaltes das 0,04-fache bis 0,05-fache des mittleren Rapskorn-Durchmessers beträgt.In the flaking of the peeled rape, it is useful the nip of the smooth rollers of the flaking mill adjusted so that the mean gap width of the nip 0.04 times to 0.05 times the average rapeseed grain diameter.
Die in dem Silo gesammelten Nebenprodukte können einer weiteren Verwendung zugeführt werden, beispielsweise als Futtermittel.The by-products collected in the silo can be one be used for further use, for example as Feed.
Neben dem primären Effekt des neuartigen Verfahrens, hochwertige und thermisch minimal belastete Speiseöle zu gewinnen, werden drei weitere wichtige Effekte erreicht. Erstens haben die Preßschilfer aus geschälter Rapssaat bereits wegen eines deutlich abgesenkten Rohfasergehaltes gegenüber Schilfern aus ungeschälter Saat einen deutlich erhöhten Futterwert. Zweitens sind die niedrige Leistungsaufnahme und der geringe Verschleiß der Schneckenpresse zu nennen, wodurch sich die Standzeit wesentlich erhöht. Drittens ist mit der energetischen Nutzung der abgetrennten Nebenprodukte, insbesondere aber der Schalenfraktion, eine CO2-neutrale Vollversorgung des Produktionsprozesses sowohl mit elektrischer als auch thermischer Energie gegeben.In addition to the primary effect of the novel process of extracting high-quality and minimally thermally contaminated edible oils, three other important effects are achieved. First of all, the pressed reeds made from peeled rapeseed already have a significantly higher feed value because of a significantly reduced crude fiber content compared to reeds made from unpeeled seeds. Secondly, the low power consumption and the low wear of the screw press are to be mentioned, which significantly increases the service life. Third, the energetic use of the separated by-products, but especially the shell fraction, provides a CO 2 -neutral full supply of the production process with both electrical and thermal energy.
