  • These windows (14) are large and arranged at locations where the electromagnetic waves can be sent to the entire plant mass introduced into the enclosure and up to its heart.
  • the waves are brought by a waveguide (40) to a plurality of windows arranged longitudinally and on each side at intervals regular or not along the stack of wood (3) to obtain a distribution the the most homogeneous waves possible.

  • an impedance adapter (41) and a 3-decibel divider (42) with an insulator (43) and the electromagnetic wave generator (44) of frequency in a frequency range between 1 MHz and 16 GHz.
  • Stack of wood or of woody plants preferably consists of pieces (30) under form of branches, beams or planks or planks of thickness and any width, from pruning or sawing and arranged for beams, planks or planks contiguously across their width or for bundle branches in a longitudinal direction to form a layer.
  • Each layer of wood or plants is spaced from the bottom layer by battens or rods (33) arranged perpendicularly so contiguous to spare between the contiguous layers or bundles of plants of air, wave, and water circulation passages.
  • the air circulation circuit is also made of material favoring the reflection of waves towards the interior of the enclosure and the wood.
  • the speaker is connected by a pipe (15) with a steam generator system (2) and possibly an air compressor (20). Moisture comes from the generator steam by diffusion grids (13), which allows it to be diffused from homogeneously in the enclosure without risk of creating frontal attacks on wood.
  • the air compressor (20) is used to produce air tablet intended to accelerate the circulation of water in the wood and, when the steam generator system (2) cannot generate steam under enough pressure to rise to the desired temperature or to support the rise in temperature and accelerate the circulation of water from wood. However, when using a steam generator system under sufficient pressure to reach temperatures and pressures the air compressor can be omitted.
  • the enclosure has means of loading and unloading the masses of plants to treat and recovery means of juice or liquid exudate extract Plant.
  • the wheels of the carriage rest on rails (10A, 10B) integral with the bottom of the tank (1) these are provided with a device for eliminating electric arcs.
  • a grid (19) avoids the wave propagation to liquid exudates or runoff collected in the bottom of the tank.
  • This runoff is discharged by a pipe (18) controlled by a valve (17).
  • This pipeline (18) opens into a removable or drainable recovery container liquid exudates resulting from the drying process.
  • the pipeline is open permanently or intermittently.
  • the upper part of the tank has a safety valve (11) which keeps the tank at the desired pressure, releases pressure if it is too high and finally put the tank in the atmosphere once the drying process completed.
  • the tank (1) is enclosed in an enclosure (5), which communicates through the airlock of the door (16) automatically controlled at the end and at the start by a system electronic control.
  • a preloading area (50) makes it possible to bring the carriages on a pair of rails (10C, 10D) which are not related electric with the rails (10A, 10B) of the enclosure (1).
  • a device for spraying (52) allows water to be sprayed during the use phase waves to prevent any leakage of radiation to the outside.
  • a tank reserve not shown, removable and drainable is connected to the enclosure (1) by a pipe (18) and makes it possible to collect the liquid exudates resulting from drying the wood.
  • the electromagnetic wave generator (44) is buried like the tank of reserve (6) and communicates with the drying chamber (1) through the guide wave (40).
  • FIG. 3 represents a second alternative embodiment of the enclosure in which on either side of the enclosure are arranged three windows (14 I), each of the windows facing a generator microwave (43) having a power, for example, of the order of 1000 watts, this power being controlled through a respective link (431), by a control system (48) which makes it possible to adapt, for each wave, power, depending on the temperature rise that we want to create by the waves inside the plant.
  • the enclosure also has a container (45) of sufficient size to allow the capacity of a mass of water corresponding to about four times the mass of air contained in the enclosure when it is at atmospheric pressure and temperature ambient outside air.
  • a heating resistor (46) arranged in the container (45) allows the temperature of the body of water to rise and gradually bring it to the vapor state while raising the pressure inside the enclosure.
  • This resistor (46) is connected to a circuit control (47) integrated or not in the control system (48) which controls the supply of the resistor according to the temperature of saturated steam desired for processing materials and a signal pressure supplied by a pressure sensor not shown allowing providing a signal to the control circuit (47) representing a correlation between the total pressure prevailing inside the enclosure and the temperature of saturated vapor created in this enclosure by heated water.
  • the amount of water required to reach the vapor state saturating obviously depends on the temperature at which one wishes perform the treatment of the plant mass but we can consider that in the saturated vapor temperature range which varies from 90 to 170 ° C, the mass required in relation to the mass of dry air contained in the enclosure at the start is of the order of two to four times the mass of air. Well Obviously, if you put too much water, it will remain at the bottom of the container and not will not transform into a vapor state, unless it still goes up in temperature and therefore pressure.
  • the temperature of 90 ° C corresponds to a total pressure prevailing inside the enclosure of 1.5 bars.
  • pressure total means the air pressure plus the saturated vapor pressure.
  • the saturation vapor temperature of 100 ° C corresponds to a pressure total pressure of 2 bars and 170 ° C at a total pressure of 9.6 bars.
  • the desirable conditions to extract the juices had to be a total pressure greater than the atmospheric pressure, and an ambient temperature in the enclosure higher than 100 ° C. As long as the ambient temperature is below 100 ° C, the juices contain very few molecules interesting for the chemical industry. Once the ambient temperature of 100 ° C has been reached, the temperature of the pile of woody material increases and juices can be recovered if it exceeds 170 ° C and therefore; the pressure of 9.6 bars, the molecules are either altered or have been destroyed.
  • the temperature and pressure increases can be done in stages successive or according to ramps or according to cycles allowing optimization of the desired result, namely production of juice or drying of woody materials.
  • the power of electromagnetic waves will be also controlled so that a slight temperature gradient so pressure materializes from the center of the pile outwards, the generators located near the extreme areas of the battery emitting a slightly lower power.
  • the frequency of the waves electromagnetic is adapted to the dimensions of the mass of material plants to be treated in the enclosure, so as to allow the penetration of waves to the heart of the plant mass to be treated and can be chosen in the frequency range from 1 MHz to 16 GHz.
  • the frequency of the waves can be chosen in the microwave range between 400 MHz and 2450 MHz or for applications requiring high penetration of waves. Frequencies of the order of 13 or 17 MHz can be used or even between 17 and 400 MHz.
  • the species will be chosen in depending on the desired results. For example, when dealing with beech, oak pedunculate or oak, we obtain a high calcareous folin index which is the sign of the presence of molecules interesting for industry chemical.
  • the pH formed by formic and acetic acids is also higher than for juices obtained by extraction processes traditional.
  • tannins wyskiline, gaiacole, phenol, and polyphenols.
  • Phenols are the basic products for thermosetting polymers or polymers thermoplastics. Polyphenols allow the production of anti-radicals free (anti-aging products).
  • terpene or insecticides By treating willow and poplars, salicylic acid can be extracted. Pine processing Sylvan produces insecticides. Similarly, poplar, we can extract salicylic acid.

  • the process also allows, in addition to the production of juice, obtain dried plant material for other applications, such as the manufacture of poles, dried wooden barriers or the use of other parts of dried plants as additives in for example the manufacture of insulating materials.
  • any transfer device can be used in place of the rail-mounted cart.
  • devices control and regulation will initiate the phases successive steps of the process in combination with more automation where less push.
  • the enclosure has a safety valve (11) allowing the enclosure to be vented, either at the end of the process or excess pressure detected by the control system.
