Abstract
Description
Die Erfindung betrifft ein Verfahren zum gleichzeitigen Zerkleinern und Kühlen von festen Substanzen mittels eines Schneidmischers, wobei in mindestens einer Vakuumphase der Schneidmischer evakuiert wird, und in mindestens einer Kühlphase tiefkaltes verflüssigtes Gas in den Schneidmischer eingeleitet wird, sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for the simultaneous comminution and cooling of solid substances by means of a cutting mixer, the cutting mixer being evacuated in at least one vacuum phase and cryogenic liquefied gas being introduced into the cutting mixer in at least one cooling phase, and a device for carrying out the method.
Zum Zerkleinern von organischen bzw. anorganischen Substanzen aller Art, insbesondere zur Verarbeitung von Gewebeteilen, tierischer und/oder pflanzlicher Natur, zu Brät, Granulat etc. benutzt man überlicherweise eine Schneidmaschine, die "Schneidmischer" oder "Kutter" genannt wird. In einem Kutter werden beispielsweise Fleischteile zu Wurstbrät oder Kakaofrüchte zu einer Grundmasse für die Schokoladenherstellung zerkleinert und gemischt. Die zu verarbeitenden Substanzen werden hierzu bekanntermaßen in einen Behälter eingegeben, der eine Zerkleinerungs- und/oder Mischeinrichtung aufweist. Üblicherweise werden die Substanzen in eine in einem Maschinengestell rotierende Schüssel gegeben. Die Schüssel steckt auf einer vertikalen Drehwelle, die z.B. von einem Elektromotor angetrieben wird. Durch diese rotierende Schüssel werden die Substanzen in einen Schneidraum, in welchem Messer mit hoher Umfangsgeschwindigkeit laufen, transportiert. Durch mehrmaliges Durchführen der Substanzen durch den Schneidraum werden diese zerkleinert und durchmischt.For the comminution of organic or inorganic substances of all kinds, in particular for processing tissue parts, of animal and / or vegetable nature, into sausage meat, granules etc., a cutting machine is usually used, which is called a "cutting mixer" or "cutter". In a cutter, for example, meat parts are crushed into sausage meat or cocoa pods into a base for chocolate production and mixed. As is known, the substances to be processed are placed in a container for this purpose has a comminution and / or mixing device. The substances are usually placed in a bowl rotating in a machine frame. The bowl is placed on a vertical rotary shaft, which is driven by an electric motor, for example. Through this rotating bowl, the substances are transported into a cutting room, in which knives run at high peripheral speeds. By repeatedly passing the substances through the cutting area, they are crushed and mixed.
Die Einbringung mechanischer Energie durch die rotierenden Messer ist zwangsläufig mit einem Temperaturanstieg der zu zerkleinernden Substanzen verbunden. Dies ist jedoch gerade bei der Verarbeitung tierischer und/oder pflanzlicher Gewebeteile unerwünscht, da z.B. Fette bei den hierbei erreichbaren Temperaturen schmelzen und Denaturierungen an Eiweißteilen auftreten können. Andererseits sollen die Substanzen oft auch schon während des Zerkleinerungsvorgangs tiefgekühlt und konserviert werden.The introduction of mechanical energy by the rotating knives is inevitably associated with an increase in the temperature of the substances to be shredded. However, this is undesirable especially when processing animal and / or vegetable tissue parts, since e.g. Melt fats at the temperatures that can be reached and denaturations on protein parts can occur. On the other hand, the substances should often be frozen and preserved even during the grinding process.
Daher wird üblicherweise ein Kältemittel in den Behälter eingeleitet. Die EP-A-0195 919 beschreibt z.B. einen Kutter mit einem druckfesten und gasdicht verschließbar ausgebildeten Kutterbehälter zur Aufnahme von Gewebeteilen. Der Behälter wird in einer Vakuumphase zunächst evakuiert, um negative Einflüsse des Luftsauerstoffs auf die zu behandelnden Gewebeteile auszuschließen und eine Öffnung des Zellgewebes zu bewirken. In einer nachfolgenden Kühlphase wird tiefkaltes verflüssigtes Gas mittels eines Injektors direkt in die Gewebeteile eingebracht.Therefore, a refrigerant is usually introduced into the container. EP-A-0195 919 describes, for example, a cutter with a pressure-resistant and gas-tight sealable cutter container for receiving tissue parts. The container is first evacuated in a vacuum phase in order to exclude negative influences of the atmospheric oxygen on the tissue parts to be treated and to open the cell tissue. In a subsequent cooling phase, cryogenic liquefied gas is introduced directly into the tissue parts using an injector.
Bei mangelnder Abfuhr des im Behälter verdampfenden Gases treten erhebliche Probleme im Umfeld des Kutters z.B. durch vermehrte Nebelbildung auf. Außerdem bewirkt das sich im Behälter ansammelnde Stickstoffgas einen ständig steigenden Überdruck im Behälter, was z.B. beim Öffnen des Behälters Probleme mit sich bringen kann.If the gas evaporating in the container is not removed, considerable problems arise in the vicinity of the cutter, e.g. due to increased fog formation. In addition, the nitrogen gas accumulating in the container causes a constantly increasing overpressure in the container, which e.g. can cause problems when opening the container.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß während der Kühlphase enstehendes Abgas abgezogen wird. Damit können Beeinträchtigungen im Umfeld des Schneidmischers verhindert werden.This object is achieved in that exhaust gas generated during the cooling phase is drawn off. This can prevent impairments in the vicinity of the cutting mixer.
Bevorzugterweise wird das Abgas über ein Absperrventil abgezogen, das während der Vakuumphase geschlossen gehalten und zu Beginn der Kühlphase geöffnet wird. Auf diese Weise wird sichergestellt, daß einerseits während der Vakuumphase ein ausreichendes Vakuum erreicht bzw. aufrechterhalten wird und andererseits während der Kühlphase eine ausreichende Abkühlung der Substanzen erzielt wird. Durch die Erfindung werden also beide Prozeßabläufe auf einfache und technisch elegante Weise optimiert.The exhaust gas is preferably drawn off via a shut-off valve which is kept closed during the vacuum phase and opened at the beginning of the cooling phase. In this way it is ensured that, on the one hand, a sufficient vacuum is achieved or maintained during the vacuum phase and, on the other hand, sufficient cooling of the substances is achieved during the cooling phase. The invention thus optimizes both process flows in a simple and technically elegant manner.
In einer vorteilhaften Ausführungsform der Erfindung ist vorgesehen, daß das Öffnen und Schließen des Absperrventils über einen pneumatisch gesteuerten Sperrkolben erfolgt. Dabei kommt ein Absperrventil zur Anwendung, das einen in einem Ventilgehäuse verschiebbar angeordneten Sperrkolben aufweist. Das Abgas wird durch eine Öffnung in das Ventilgehäuse eingeleitet und durch eine zweite Öffnung wieder herausgeführt. Während der Vakuumphase wird der Sperrkolben pneumatisch soweit in Richtung auf die erste Öffnung verschoben, daß er die Öffnung verschließt. Zu Beginn der Kühlphase wird der Sperrkolben zurückgeschoben, sodaß ein Strömungsweg des Abgases von der einen zur zweiten Öffnung des Ventilgehäuses freigelegt wird. Das Abgas wird zweckmäßigerweise mittels eines Ventilators abgezogen.In an advantageous embodiment of the invention it is provided that the shut-off valve is opened and closed via a pneumatically controlled locking piston. A shut-off valve comes into play Application that has a locking piston displaceably arranged in a valve housing. The exhaust gas is introduced into the valve housing through an opening and out again through a second opening. During the vacuum phase, the locking piston is pneumatically displaced towards the first opening until it closes the opening. At the beginning of the cooling phase, the locking piston is pushed back, so that a flow path of the exhaust gas from one to the second opening of the valve housing is exposed. The exhaust gas is expediently drawn off by means of a fan.
Bevorzugterweise wird als tiefkaltes verflüssigtes Gas flüssiger Stickstoff verwendet. Stickstoff ist gegenüber tierischen oder pflanzlichen Gewebeteilen als inertes Gas anzusehen, sodaß keine Beeinträchtigungen produktspezifischer Eigenschaften auftreten. Außerdem ist durch die Anwendung flüssigen Stickstoffs eine ausreichende Kühltemperatur sichergestellt.Liquid nitrogen is preferably used as the cryogenic liquefied gas. Nitrogen is to be regarded as an inert gas compared to animal or vegetable tissue parts, so that there is no impairment of product-specific properties. Adequate cooling temperature is also ensured through the use of liquid nitrogen.
Die vorliegende Erfindung bietet insbesondere bei der Verabeitung von tierischen und/oder pflanzlichen Gewebeteilen Vorteile. Durch die sichere Aufrechterhaltung des Vakuums während der Vakuumphase werden einerseits negative Einflüsse des Luftsauerstoffs erfolgreich ausgeschaltet, wodurch sich eine verbesserte Qualität der verarbeiteten Gewebeteile, d.h. der Wurst, der Kakaofrüchte etc., ergibt. Andererseits wird eine schnelle Temperaturabsenkung erreicht, was ebenfalls der Qualität der verarbeiteten Substanzen zugute kommt.The present invention offers advantages in particular in the processing of animal and / or vegetable tissue parts. By reliably maintaining the vacuum during the vacuum phase, negative influences of the atmospheric oxygen are successfully eliminated on the one hand, which results in an improved quality of the processed tissue parts, ie the sausage, the cocoa pods, etc. On the other hand, a rapid temperature reduction is achieved, which also benefits the quality of the substances processed.
