The invention relates to a method for producing natural rubber. The novel method for drying natural rubber is based on the basic principle of friction heat generation, uses a barrel/screw extrusion mechanism to apply a force to a bulk gel of rubber to further expulse free water, and then compresses the rubber by the relative movement of the screw and the barrel, a mechanical friction is carried out for rubber granules in a drying device to raise the temperature and pressure of the rubber through self mechanical friction of rubber against the mechanics; after the energy repertory of rubber arrives at a certain level, a principle of adiabatic flash is used to achieve the separation of water from natural rubber within the mechanics, thereby accomplishing the drying of natural rubber. A friction heat generation method is adopted by the invention to convert the mechanical energy to heat energy to heat the rubber, and then make temperature thereof rise without intermediate process of energy transmission, thereby shortening the time needed by baking technology by more than 120 times, significantly improving the quality of the rubber, and producing a rubber with a pale color nearing the natural color.
