Title Method of processing plant
Abstract (US8216506)
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.
Scope of claims [claim1]
1. A method for processing a plant, comprising the steps of: (a) liquid-fluidizing a piece of a plant containing moisture by applying a pressure and a heat to the piece of the plant in a hermetically-closed state in a forming mold while retaining the moisture contained in the piece of the plant by substantially disabling ventilation of water vapor between an atmosphere inside the forming mold and an atmosphere outside the forming mold, the piece of the plant not having been reduced to a powder;
(b) pressure-molding the piece of the plant having the liquid fluidity into a molded article having a predetermined shape while in the hermetically-closed state;
(c) removing, by ending the hermetically-closed state, moisture contained in the molded article made from the piece of the plant; and
(d) restoring an ambient pressure and an ambient temperature after the step (c) is carried out, thereby yielding the molded article,
wherein the moisture content of the piece of the plant is not less than 10% by weight, and a pressure of 100 MPa or greater is applied to the piece of the plant while heating the piece of the plant to a temperature not less than 130 deg. C. but not more than 200 deg. C.
[claim2]
2. A method for processing a plant, comprising: a first step including setting, inside a forming mold, a piece of a plant which contains moisture and which has not been reduced to a powder,
hermetically closing the forming mold by substantially disabling ventilation of water vapor between an atmosphere inside the forming mold and an atmosphere outside the forming mold, and
applying a heat and a pressure to the piece of the plant so as to liquid-fluidize the piece of the plant, and pressure-molding the piece of the plant thus liquid-fluidized while in the hermetically-closed state;
a second step of, after the piece of the plant reaches a predetermined molding temperature and a predetermined molding pressure, enabling ventilation of water vapor between the atmosphere inside the forming mold and the atmosphere outside the forming mold and thereby removing moisture from a molded article made from the piece of the plant; and
a third step including retaining the predetermined molding pressure and the predetermined molding temperature for a predetermined period;
cooling the molded article thus made from the piece of the plant; and
taking out the molded article from the forming mold,
wherein the moisture content of the piece of the plant is not less than 10% by weight, and a pressure of 100 MPa or greater is applied to the piece of the plant while heating the piece of the plant to a temperature not less than 130 deg. C. by not more than 200 deg. C.
[claim3]
3. The method for processing a plant as set forth in claim 1, wherein the piece of the plant is a piece of wood.
[claim4]
4. The method for processing a plant as set forth in claim 2, wherein the piece of the plant is a piece of wood.
[claim5]
5. The method for processing a plant as set forth in claim 1, wherein the piece of the plant is a single piece of wood.
[claim6]
6. The method for processing a plant as set forth in claim 2, wherein the piece of the plant is a single piece of wood.
