Definitions
- the invention relates to a device and a method for the continuous high-pressure treatment of bulk material, in particular by extraction and / or impregnation.
- the invention relates to the use of a pressure vessel device with at least one actuator for adjusting the material flow in the continuous high-pressure treatment of bulk material.
- the invention relates to a device and a method in each case according to the preamble of the respective independent claim.
- Both liquids (fluids in the liquid phase, in particular also viscous fluids) and solids can be subjected to extraction as starting materials.
- Both the high-pressure treated bulk material (also referred to as raffinate in this state) and extracts obtained by extraction can, depending on the application, be called the product of high-pressure treatment.
- Prominent examples of extraction processes are the decaffeination of tea leaves, coffee beans or the extraction of hops. Since the extraction is related to the manufacture of various intermediate and end-user products, especially from the food industry, the number of variants is also different from Extraction process comparatively high. This is also reflected in the different variants with regard to construction and the size range of the systems. For example, it is not uncommon to realize an extraction column with a height of more than 10m, or to connect several extractors (pressure vessels) to one another. In any case, a large variety of variants can be observed in the existing system concepts, also with regard to size variations.
- Comparable examples can be enumerated for impregnation processes, be they carried out separately or in combination with an extraction.
- extraction in particular extractive solvent removal
- a basket-like insert which is also referred to as a product holding basket, is usually used to arrange the bulk material in the high-pressure treatment volume (i.e. in the receiving cavity for the granulate defined by the pressure container), for example with a volume of approx.
- the basket-like insert can be introduced into the area of a lid of the extractor, and after the extraction, the bulk material largely freed from solvent can be removed for further use by removing the basket-like insert.
- the next batch can then be arranged in the extractor using the same or a further basket-like insert.
- the high-pressure treatment process is carried out in batches, and the basket-like use is also intended to facilitate the handling of the respective batch.
- a disadvantage of previous devices and methods is not only the handling of the bulk material (material flow), but also the dusts or gases that form, in particular explosive gas mixtures, and health impairments for the people involved. There is therefore interest in simplifying high-pressure treatment processes for bulk goods, in particular for large quantities of bulk goods, in particular for extraction and / or impregnation.
- JP 1293129 A describes a high-pressure process in which a storage container and a collecting container facilitate the batch-wise provision of bulk material in the high-pressure chamber, the bulk material sliding gravitationally in batches through a high-pressure treatment chamber as a function of the supply and discharge.
- CN 1827201 A describes a high-pressure treatment process in which the high-pressure container is conveyed through a type of pressure lock.
- DE 42 16 295 A1 describes a method for high-pressure treatment in which a container which is open on both sides is used, an advantageous throughput or an advantageous process control being able to be ensured by means of a translatory movement of a piston and by means of several chamber regions.
- EP 1 725 706 B1 describes the transfer of pretreated solid as a suspension to a high pressure stage.
- the object of the invention is to provide a device and a method with the features described at the outset, with which the high-pressure treatment of bulk material can be simplified or the device or process engineering outlay associated with the high-pressure treatment can be reduced, in particular with the highest possible efficiency of the method (Throughput per unit of time). Aspects of Occupational safety and health risks can be taken into account. Last but not least, there is also interest in a (time-) efficient high-pressure treatment process, especially for extraction, especially extraction of solvent (s), and / or for the impregnation of bulk goods of very different types, so that the process - despite any optimization measures with regard to efficient high-pressure treatment (Keyword: maximized throughput) - can guarantee the greatest possible variability.
- This object is achieved according to the invention by a method for high-pressure treatment of bulk material by extraction and / or impregnation, which bulk material is arranged in the high-pressure treatment volume of a pressure vessel device and is treated at a high-pressure level, in particular high pressure in the range from 40 to 1000 bar, with isolation from the environment, whereby the method comprises at least the three following step sequences which can be individually regulated (in particular with regard to material flow): pressurization V1, high pressure treatment V2, relaxation V3.
- the high-pressure treatment or the high-pressure treatment in the second step sequence V2 is carried out in a continuous manner at the high-pressure level in a closed system in the high-pressure treatment volume, the high-pressure treatment volume or the entire pressure vessel device being / remaining stationary (static) during the high-pressure treatment, whereby the continuity of the high-pressure treatment or the high-pressure treatment sequence of steps is ensured solely by means of the one (single) high-pressure treatment volume Vi, and the bulk material is conveyed by the high-pressure treatment volume by means of a rotary actuating movement or as a function of at least one translatory actuating movement, in particular by continuous or discontinuous relocation of a single batch or a plurality of partial batches.

- the discontinuous procedure upstream and downstream of the high-pressure treatment
- the high pressure range from 40 to 1000 bar can be further differentiated depending on the application.
- the advantageous high-pressure range can be restricted to 40 to 400 bar or 50 to 300 bar and / or to 650 to 1000 bar.
- the solution properties of the extraction medium can in particular also be set or changed.
- Process-related advantages can also arise in the high pressure range from 100 to 250 bar, in particular 100 to 200 bar.
- a pressure range below or above a critical point of an extraction medium used (for example C0 2 ) can be set.
- Either a pure substance or a mixture of substances can be used as the extraction medium, especially with process parameters above the critical point of the substance or above a critical line of a two-substance mixture or above a critical area of a mixture of substances from more than two substances (especially three-substance mixtures).
- a continuous high-pressure treatment is to be understood as a high-pressure treatment in which no process interruption due to pressure fluctuations and / or due to material flow is required for the high-pressure treatment of the bulk material, but in which the high-pressure treatment at the high-pressure level is optionally continuously unchanged without any time interruption and (at least theoretically ) can be carried out without time restriction and (at least theoretically) without restriction with regard to the amount (mass, volume) of the bulk material treated, in particular also with continuous material flow within the high-pressure treatment volume.

- a temperature level in the high pressure treatment volume can also be set; in particular, a constant temperature can be maintained.
- a temperature cycle in the High-pressure treatment volumes are driven, especially in connection with the supply and / or discharge of material.
- a stationary arrangement is to be understood as a static arrangement in which the high-pressure treatment volume or the corresponding high-pressure treatment cavity delimited by the pressure container device (or by its wall) can remain arranged in a stationary manner.
- the pressure vessel device or the entire arrangement does not have to take on any function with regard to bulk material shifting by shifting the high-pressure treatment volume.
- no displacement of the high-pressure treatment volume relative to the other components of the arrangement is necessary.
- the material flow function does not have to be fulfilled by means of the high-pressure treatment volume.
- high-pressure treatment volume does not have to be moved (neither absolutely nor relatively) in order to ensure the continuity of the process (continuous material flow). Rather, the bulk material can be supplied to the high-pressure treatment volume and discharged again without having to interrupt the high-pressure treatment.
- One or more (continuous or discontinuous) actuating movements can optionally be carried out within the high-pressure treatment volume, in particular to define a specific type of material flow in the continuous high-pressure treatment, but the high-pressure treatment volume can remain stationary. This not least facilitates the coupling of the high-pressure treatment volume to the first and third sequence of steps, and last but not least, there are also advantages with regard to the pressure-tight design of the entire arrangement.
- a single or single high-pressure treatment volume is to be understood as an embodiment in which the high-pressure treatment does not have to be carried out in successive individual volumes, but in which the respective batch is arranged only once in a single container, in a single cavity or in a single volume and is subjected to high pressure treatment.
- the high-pressure treatment volume can limit the entire material flow path of the bulk material provided for the high-pressure treatment.
- the high-pressure treatment volume can therefore also be as a high pressure treatment cavity enclosed by the pressure vessel device in a high pressure-tight manner can be described.
- the high-pressure treatment time which is considerable for the design of the method, can be predefined primarily from the time required for the extraction.
- the start and end times (in the sense of a dwell time for the bulk material) of the respective phase of the high pressure treatment and their duration can be set individually depending on the bulk material and medium.
- a procedure for material flow and high pressure medium in counterflow to one another can also be advantageous.
- the high-pressure medium can correspond to an extraction medium used.
- the manner in which bulk material and high-pressure medium are guided and forwarded can be adapted to the respective application in a very varied and very flexible manner (e.g. pressure level, type of bulk material, type of solvent).
- High-pressure medium, in particular extraction medium, and bulk material can optionally also be conveyed in the same direction.
- an inclination of the pressure vessel device or the high-pressure treatment volume with respect to the horizontal can be advantageous, in particular with regard to the outflow or discharge of liquid solvent.

- the relaxation is preferably carried out in a discontinuous manner, depending on the high pressure level, in particular in several stages. The respective container can be locked for this.
- a comparatively long expansion line can optionally also be provided, in particular immediately downstream of the second sequence of steps V2.
- the expansion line enables a structurally very simple and robust arrangement and can minimize the process or system engineering effort for the expansion V3.

- this also enables a higher production capacity to be achieved than with a classic arrangement (with a comparable system size).
- Process engineering advantages can be realized in particular because the high-pressure treatment does not have to be carried out in a cycle selected in the first step sequence V1 (pressurization) and / or in the third step sequence V3 (relaxation).

- the starting material for the extraction can in many cases only be piled up to a certain height, in particular in order to avoid excessive compression.
- a pressure vessel is filled cyclically, high pressure is applied and the extraction medium flows through for high pressure treatment. The pressure vessel is then relaxed and emptied again.

In particular, the pressure must be relieved to a pressure well below the required high pressure level in order to be able to convey the bulk material further.

Ultimately, there are also economic advantages, in particular thanks to the high throughput of bulk material.
- individual partial batches are supplied to the high-pressure treatment volume and / or discharged from the high-pressure treatment volume during the high-pressure treatment. Handling the material flow in partial batches can also provide advantages in terms of pressure build-up and relaxation.
