Definitions
- the invention relates to an apparatus and a method for high-pressure treatment of bulk material by extraction and / or impregnation. Furthermore, the invention relates to the use of a support floor module with at least one treatment level for the high-pressure treatment in a closed system. In particular, the invention relates to an apparatus and a method respectively according to the preamble of the respective independent claim.
- Bulk materials in particular in the form of granules, must in many cases be freed of substances, in particular solvents.
- the bulk materials must generally be subjected to a pure extraction, independent of solvents. This can advantageously take place under high pressure, in particular at pressures above 100 bar, in particular in conjunction with the effect of heat at elevated temperature.
- An extraction, in particular extraction of solvent (s) is in many cases preferably using supercritical fluids (or extraction media), for example carbon dioxide (CO 2 ), propane, butane, in particular since surface forces can be minimized and the extraction becomes particularly effective , also with regard to a drying effect. Both fluids and solids can be extracted.
- Prominent examples of extraction methods are, for example, the decaffeination of tea leaves, coffee beans or hops extraction. Since the extraction is related to the production of various consumer products, the number of variants of extraction methods is comparatively high. This is also reflected in the structure and size of the systems. It is not uncommon, for example, to realize an extraction column with a height of more than 10 m, or several extractors (pressure vessels) together to form a plant boarded. In any case, a large variety can be observed in the existing system concepts, also with regard to size variations.
- an extractor pressure vessel
- the bulk material usually serves a basket-like use, also known as a product receiving basket, for example, with a volume of about 250 liters and cylindrical mantle wall, with a gas-permeable, wire mesh-like, hole plate-like or sintered metal filter bottom, on which the use in Extractor is supported.
- a lid of the basket can also be gas-permeable, wire mesh-like, hole plate-like or made of sintered metal.
- the basket-like insert can be introduced in the region of a lid of the extractor, and after extraction, the largely freed of solvent bulk material can be removed by removing the basket-like insert for further use.
- the next batch can then be arranged by the same or another basket-type insert in the extractor.
- the high-pressure treatment process is carried out in batches, wherein the basket-like use is also intended to facilitate the handling of the respective batch, for example the removal.
- a disadvantage of previous devices and methods are therefore in particular the forming explosive gas mixtures and the health impairments for persons involved. Therefore, there is an interest in simplifying high-pressure treatment processes for bulk materials, in particular with minimized personnel expenditure, in particular for large quantities of bulk material, in particular for extraction and / or impregnation.
- the object of the invention is to provide an apparatus and a method with the features described above, whereby the high-pressure treatment can be simplified or the apparatus or process-related expense associated with the high-pressure treatment can be reduced.
- the operational and / or work safety should be increased.
- a pressure vessel device adapted for high-pressure treatment of bulk material by extraction and / or impregnation, with a lid and a high-pressure resistant wall, which surrounds a wall of the environment by means of a cover pressure-sealed or fusible inner volume, and with a to the Internal volume coupled inlet fitting and an outlet fitting respectively for the bulk material;
- the pressure vessel device comprises a tray module having a plurality of actuatable ones Treatment levels has which support floor module or which treatment levels are arranged / arranged in such a way in the inner volume and partial load with bulk material are loaded with bulk material and closed at high pressure level high pressure treatment with closed pressure vessel device teilchargenweise dischargeable or aktuierbar that the high-pressure treatment in a closed, from The environment foreclosed system is executable. This also allows a process with reduced process engineering effort, especially with regard to manual activities, and facilitates not least the process automation.
- the loading and extraction and / or impregnation (high-pressure treatment) in a closed system also has the advantage that explosion protection must meet less stringent requirements. Measures for operational safety can therefore remain relatively inexpensive. Also, a risk that a high-pressure seal is not done correctly, can be greatly minimized.
- the inner volume preferably corresponds to an empty cavity, in particular with a cylindrical geometry, optionally conical at the outlet.
- each treatment level for example, 30 to 100 kg of bulk material or granules are picked up, in particular approx. 55kg.
- the inner volume defined by the pressure containing device is, for example 100 liter to 10 m 3 or even up to 20m. 3 In the
- Food handling for example, volumes in the range of 3 to 5m 3 are used, especially at a high pressure of about 300 to 600bar.
- the volume of the bulk material taken up in the internal volume is, for example, 50 L to 5 m 3 or even up to 10 m 3 , provided that the bulk material swells during extraction.
- Non-swelling bulk material can optionally also occupy a larger volume fraction of the internal volume, for example 0.7 to 0.8 times the internal volume.
- the volumes mentioned here are to be understood as examples.
- the inventive arrangement or the inventive method can also be realized for smaller volumes, for example on a laboratory scale, for example with 5 to 25L, for example in extraction autoclaves.
- any bulk material be it artificial or made-up material or natural substances as well as food, such as polymer beads, or coffee beans, or hops.
- the granules need not necessarily be preformulated for the process, but may also be a natural product or foodstuff intended for high pressure treatment immediately after recovery (e.g., spice, herbs).
- the high-pressure treatment according to the invention can also be used e.g. be used for cleaning metal or plastic parts.
- the bulk material or granules can be present in a wide range of hardness, for example, it can also be comparatively soft.
- the bulk material can be swelling (volume increase) or shrinking or compacting (volume decrease), regardless of the degree of hardness.
- the granules have e.g.
- the bulk material may be swelling at considerable volume change, for example by a factor of 2 to 10 (in particular based on the diameter or volume), for example from 5mm to 10mm particle diameter. Swelling bulk material can be metered in such a way that the respective treatment level still has a buffer volume even after swelling; For example, only about 50% of the loading capacity of the treatment level is loaded before the high-pressure treatment. An arrangement of the bulk material on several levels also allows a swelling behavior, which is not or hardly noticeable influenced by gravity influences.
- the method according to the invention is advantageous not only for extraction treatments, but also for Impregnation treatments.
- a combination of both treatment methods can also be carried out, in particular in the closed system optionally at least at approximately the same high pressure level.
- the respective treatment level does not have to be strictly horizontal or exactly plan.
- the respective treatment level serves the arrangement of the bulk material, in particular with predefined layer thickness. If the supply and / or discharge should take place in the lateral direction, it may be advantageous to tilt the treatment level and / or to design it with a curvature.
- closed pressure vessel device or as a closed system is to be understood an arrangement in which at least one lid of the pressure vessel device remains mounted. A removal of inlet baskets or the like receptacles out of the pressure vessel device is not required; the pressure vessel device can remain closed.
- the pressure vessel device has an automatically actuatable inlet fitting for the batchwise feeding of the bulk material, in particular coupled to the lid.
- the pressure vessel device has an automatically actuatable outlet fitting for the batch discharge of the bulk material, in particular coupled to a bottom of the pressure vessel device.
- Automated actuation can be carried out in particular by means of a control device set up for this purpose.
- the at least one treatment level is adapted to receive the bulk material in a particular horizontally oriented plane and further adapted for the passage of bulk material. This also provides flexibility in the manner of loading / unloading the Pressure vessel device, in particular in a controlled in several sub-batches process.
- the support floor module has a plurality of actuatable treatment levels, which can be loaded / unloaded with bulk material in each case when the pressure container device is closed.
- actuatable treatment levels which can be loaded / unloaded with bulk material in each case when the pressure container device is closed.
- At least one partial region of the respective treatment plane can be displaced from a corresponding high-pressure treatment position into at least one loading / unloading position, in particular by means of pivoting kinematics.
- This also has advantages in terms of material flow.
- the material flow can be organized by gravity.
