Definitions

  • 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.
  • a cutting machine for example, meat parts are crushed into sausage meat or cocoa pods into a base for chocolate production and mixed.
  • the substances to be processed are introduced into a container which has a comminution and / or mixing device.
  • the substances are usually placed in a bowl rotating in a machine frame.
  • the bowl is on a vertical rotary shaft, which is driven by an electric motor, for example.
  • the substances are transported into a cutting space, in which knives run at high peripheral speeds. By repeatedly passing the substances through the cutting area, they are crushed and mixed.
  • EP-A-0 195 919 describes e.g. a cutter with a pressure-resistant and gas-tight lockable 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.
  • cryogenic liquefied gas is introduced directly into the tissue parts using an injector.
  • DE-A-3 344 521 describes a vacuum cutter for meat processing, liquid nitrogen being used to cool the cutter. There is no provision for the removal of gaseous nitrogen.
  • 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.
  • 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.
  • the present invention has for its object to design a method of the type mentioned so that the problems described do not occur.
  • This object is achieved in that the resulting exhaust gas is drawn off via a shut-off valve which is kept closed during the vacuum phase and opened at the beginning of the cooling phase.
  • the shut-off valve is opened and closed via a pneumatically controlled locking piston.
  • a shut-off valve which has a locking piston which is 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.
  • the locking piston pneumatically moved so far in the direction of the first opening that it closes the opening.
  • 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.
  • 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. In addition, the use of liquid nitrogen ensures an adequate cooling temperature.
  • the present invention offers advantages in particular when processing 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 improves the quality of the processed tissue parts, i.e. the sausage, cocoa pods, etc.
  • a rapid temperature reduction is achieved, which also benefits the quality of the substances processed.
  • the invention can also be used in the shredding of rubber parts, plastic parts and similar materials.
  • the container 2 When operating the cutter shown in FIG. 1, fresh tissue parts 6 are filled into the container 2 up to the fill level 8.
  • the container 2 is first evacuated by means of the vacuum pump 10.
  • the shut-off valve 12 is closed. If the desired vacuum, which is dependent on the tissue parts to be processed, has been reached, the vacuum pump 10 is switched off.
  • the liquid nitrogen is then introduced into the container 2 via the feed nozzle 1.
  • the vacuum is released by the nitrogen evaporating in container 2.
  • the shut-off valve 12 is opened.
  • the exhaust gas generated during the cooling phase is drawn off by the fan 14 via the line 11, the opened shut-off valve 12 and the line 15.
  • the shut-off valve which is only indicated in FIG. 1, is shown in more detail in FIG.
  • the shut-off valve has a valve housing 21, on which a supply nozzle 22 for supplying the exhaust gas into the valve housing 21 is attached.
  • a discharge connection 23 is connected to the valve housing 21 perpendicular to the supply connection 22, via which the exhaust gas can be drawn off from the valve housing 21.
  • a locking piston 24 axially displaceable to the supply nozzle 22 is arranged.
  • the locking piston 24 is connected to a pressure cylinder 25 through which it can be moved.
  • the pressure cylinder 25 has supply lines 26 for pressure-supplying means, for example compressed air.
  • shut-off piston 24 When the shut-off valve is operating, the shut-off piston 24 is displaced in the direction of the supply nozzle 22 at the beginning of the vacuum phase so that it is closed. Thus, no exhaust gas can escape from the cutter container via the shut-off valve. At the beginning of the cooling phase, the locking piston is then moved in the opposite direction to such an extent that the supply nozzle 22 and the discharge nozzle 23 are connected. The exhaust gas can now escape from the cutter tank via the shut-off valve.
  • valve housing is designed to be rotatable, so that the discharge nozzle 23 can be rotated through 360 ° about the axis of the supply nozzle 22. In this way, the greatest possible adaptation to different cutters is possible.
  • the valve housing 21 is removable after loosening a simple spring clip 27, so that the interior of the shut-off valve is easily accessible for cleaning or repairs.
