METHOD OF PROCESSING PLANT
One embodiment of the present invention includes: a step of setting a piece of a plant containing moisture inside a pressurizing apparatus and hermetically closing the internal space of the pressurizing apparatus
a step of applying a heat and a pressure to the piece of the plant
and a step of (i) enabling ventilation between the inside of the pressurizing apparatus and outside thereof after the piece of the plant reaches a predetermined molding temperature, (ii) retaining the pressure and the temperature for a predetermined period, (iii) cooling a molded article, and (iv) taking out the molded article from the pressurizing apparatus. This realizes a method for processing a plant which method makes it possible to mold a piece of a plant into a desired shape without reducing the piece of the plant into powder and without using an adhesive.
