contexte

"compression stage where the parget is compressed by the piston of the extruding
machine moving forward until it comes into contact with the blades of the reactor, which reject the parget, propelling it to the interior of the extrusion chamber, and prevent it from moving forward with the resulting increase of pressure"

"when the piston moves forward, it further compresses the parget and forces it to penetrate the boundary layer of the reactor, forming a perimeter film, [b] the reactor shaft enters into resonance, where the potential energy built up by the rotor shaft is released as an emission of a shock wave train, subjecting the parget that is inside the extrusion cavity to violent stirring, and also subjecting the parget which is in the boundary layer to pressure peaks produced by the vibration of the rotor shaft, [c] once the resonance phenomenon is finished, the pressure on the piston of the extruding machine is reduced, decompressing the parget, and the compression of the parget on the rotor is repeated until it enters into resonance once again and there is a new emission of shock waves, and [d] the resonance and decompression cycles are repeated until the temperature of the parget reaches 85QC to 98QC, preferably 92°C, "
