Estimating the term…
The invention relates to a method for extracting the natural juice of ligneous plant material, a device for carrying out said method and the use of said method in the production of dried ligneous plant material. The method for extracting the natural juice of ligneous plant material comprises the following: a pressurization step in which a sealed enclosure containing the plant material is pressurized, whereby the pressure thereof is greater than that of the atmosphere; a stage in which saturating water vapor is created or injected; a stage in which the plant material is heated to the core by means of electromagnetic waves; a step in which the liquid exudates from said plant material are gravitationally recovered.
A process for extracting natural liquor from ligneous plant matter characterised in that it comprises:
A device allowing the process to be implemented, characterised in that it is constituted by a sealed enclosure resistant to pressure by a plurality of windows made of quartz or of any other wave suiting material with an electromagnetic wave generator placed near each window, so as to emit the waves transversely to the mass of plant material placed in the enclosure, a device for generating saturated water vapour at pressure above atmospheric pressure so as to create or inject a saturated water vapour pressure at a vapour temperature and at a total pressure determined as a function of the plant to be processed.
