Definitions
- the present invention therefore aims to eliminate the aforementioned drawbacks by providing a solution which makes it possible to quickly obtain the soluble principles of a raw material, in particular a plant or a part thereof, for example its seeds, from the start of the extraction operation while avoiding the preferential paths of the extraction agent in the mass to be extracted, said solution also making it possible to significantly improve the solid / liquid contacts, the separation of the miscella from solids and finally the separation of the soluble principles from the extractant.
- this solution should be of simple design.
- the aforementioned treatment of miscella is an evaporation treatment by which, after condensation, the extraction agent is obtained as the top fraction and the soluble principles of the raw material, or extracts, as the bottom or tail fraction. .
- a fine filtration system 16 advantageously produced in duplex to allow alternating cleaning of the filters or of unclogging for example. by external, manual or automatic, periodic or continuous control, in order to eliminate fine solid particles which could have been entrained through the submerged filter 7.
- This filtration system 16 may include a drain outlet 17.
- a decantation system 18 can be interposed on the line 12 between the filtration system 16 and the storage tank 11, this decantation system 18 comprising an outlet 19 for water (in particular coming from the humidity of the raw material ) or other fraction separated by settling of the miscella.
- the capacity 1 comprises a chimney or column 52 whose upper end, opposite to the capacity 1, is advantageously connected to a safety condenser 53 preferably comprising a return circuit 54 of the condensates in the chimney 52.
- This condensate return circuit may include a decantation device 55 making it possible to separate the extraction agent which is collected by a pipe 56 in the reserve tank 27 while this decantation device 55 has an outlet 57 in condensate other than the extraction agent with possibly a recycling line 58 communicating with the circuit 54.
- the soluble principles of the extracting agent also comprising traces of extracting agent form a concentrate which is sent via line 29 to the high vacuum evaporation apparatus 30 which makes it possible to completely separate the extraction agent via line 31 and optionally send it via line 9a to the reserve tank 27, while the soluble principles of the raw material are that is to say in this case rapeseed oil, are recovered via line 10.
- Part of the concentrate obtained in the expansion cyclone 23 can be recycled through line 35 to resubmit it to the separation treatment.
- This filter or strainer 7 can be rotatably mounted around its longitudinal axis with a scraper blade fixed underneath and permanently on the capacity 1.
- This filter or strainer 7 can also be mounted telescopically on the capacity 1 so that it can be removed at least partially of the capacity 1 at the start of the grinding of the raw material to avoid damaging it when this raw material is hard.
- the filtering surface of the filter or of the strainer 7 may consist of a winding of metal wire of special profile spot welded on cylinder generators in the case where too large or too hard solids tend to damage the linings. of metallic canvas.
