solvent under super high pressure the procedures are as follows the step of pretreatment crashing and formulation the solid raw biomaterial is pretreated first including roguing cleaning or macerating and then crashed finally mix the crashed biomaterials with proper solvent by the proper ratio homogeneously the step of closure put the above mixture into the high pressure container firstly and then close the container alternatively close the container firstly and then charge the mixture into the container the step of increasing pressure the pressure of the pressure container is increased from normal pressure to the predefined pressure of 100 mpa u02dc 1000 mpa the step of holding pressure the predefined pressure is held for 3 30 minutes the step of releasing pressure the pressure of the pressure container is released to the normal pressure and the mixture is removed from the container alternatively in the step of closure the mixture is first poured into a packing container which is then airproofed after that put the packing container into the pressure container and close it charge the medium for transferring pressure into the pressure container the pressure of the pressure container is increased via the medium by a pump after holding for a period of time release the pressure of container and remove the packing container and the mixture therein the packing container may be made of flexible material such as plastic film or paper it also may be made of hard materials such as metal or glass the packing container must be pressure transferrable without.
