For example, the apparatus is applied to the processing of 0 stem of kenaf which is largely cultivated in Australia and the like. BACKGROUND ART When chemically synthesized materials are disposed of in nature, the materials remain for a long time with their 5 harmful properties maintained, thereby adversely affecting ecological systems. In recent years, in view of such a problem, there is a social demand that materials existing in nature and having properties and functions equivalent to those of the chemically synthesized artificial materials be effectively 0 utilized as much as possible in order to reduce environmental loads. Of course, the subject materials effectively utilized include plants. For example, in the case of the stem of kenaf which is largely cultivated in Australia and the like, the outer skin .5 thereof is effectively separated from parts other than the 1 GJG : PAL ZPF063AU outer skin to extract fibers, and the fibers can be utilized in place of chemical synthetic fibers. In addition, the core portion of the stem of kenaf can be utilized as a resin filler, a construction material, and paper 5 pulp. In order to realize the effective utilization of such plants, there is a strong demand for a method and an apparatus for separating, in a simple manner, a large amount of the outer skin of a plant from parts other than the outer skin. LO In conventional technologies, a method for collecting fibers by fermenting the stem of a plant through microbial fermentation, adding water, and stirring under crushing is described in Japanese Patent Laid-Open Publication No. 2002 115188, "Method for manufacturing paper-producing pulp". Or a L5 technology for retrieving bast fibers by subjecting the stem of kenaf to microbial decomposition processing and stirring the stem in water to separate the fibers from the core is described in Japanese Patent Laid-Open Publication No. 2001 336022, "Method for collecting kenaf bast fiber". 20 Furthermore, Japanese Patent Laid-Open Publication No. Sho 62-126964, "Method and apparatus for peeling outer skin of food plant," discloses a technique for "peeling" the outer skin of the stem of a plant through a water jet. Similarly, as a technology utilizing high pressure water, 25 a technology is disclosed in Japanese Translation of PCT 2 GJG: PAL ZPF063AU International Application No. Hei 11-510751, "Process for treatment of old wood." In this technology, the surface of a piece of old wood is mechanically damaged or roughened, and the piece of old wood is immersed in water and subsequently is 5 subjected to vapor treatment by means of vapor of 120 to 160 0 C to thereby separate the surface layer to be removed by means of high pressure water. These conventional technologies require long biometric fermentation or immersion time and a large amount of water. 0 Therefore, although there is no problem when water resources are in abundance, there is a problem that the implementation of the technologies is difficult when water resources are not in abundance. Furthermore, as a utilization method of largely .5 cultivated kenaf, Japanese Patent No. 2960063, "Method for producing kenaf pulp," discloses a method for collecting plant fibers by separating the stem of kenaf into core and skin, then cutting to a certain length, mixing them with water, stirring and crashing, and subjecting them to a step of ?0 boiling in water, without performing chemical processing. However, in the above Japanese Patent No. 2960063, only the method is disclosed, and a specific apparatus for efficiently implementing the described method is not explicitly shown. Moreover, Japanese Patent Laid-Open Publication No. 2001 ?5 288686, "Method for producing kenaf pulp and kenaf pulp," 3 GJG : PAL ZPF063AU discloses a method for producing raw chips by pressing raw kenaf to squeeze the juice, subjecting the raw kenaf from which the juice has been squeezed to pre-treatment for peeling the surface skin by washing with water, and cutting. However, 5 this method has a problem of requiring a large amount of water, and a specific apparatus for efficiently implementing the described method is not explicitly shown. DISCLOSURE OF THE INVENTION 0 PROBLEMS TO BE SOLVED BY THE INVENTION It is an object to provide an apparatus for separating outer skin of a plant from parts other than the outer skin simply and easily in large quantities. Moreover, it is also an object to realize a configuration capable of being implemented .5 when water resources are not in abundance. MEANS FOR SOLVING THE PROBLEMS In the present invention, a stripping container is provided in which the skin of the stem of a plant is washed with a high pressure water jet to unravel the fibers of the ?0 skin into pieces, whereby the outer skin is separated from the core. Also, a configuration is suitable which is provided also with a crushing container which is connected in series with the stripping container and in which the core is crushed with a high pressure water jet. Moreover, water feeding means may 25 be provided for purifying the used high pressure water for 4 GJG: PAL ZPF063AU reuse. Accordingly, there is provided an apparatus for separating an outer skin of a plant from parts other than the outer skin while a stem of the plant is washed (claim 1). The 5 apparatus for separating the outer skin of the plant from the parts other than the outer skin has: a stripping container for the plant stem outer skin, the container being provided with an inlet hole and an outlet hole to be opened for passing through the plant stem in a lengthwise direction and having LO thereinside a plurality of nozzles for injecting pressurized water inwardly; a plant feeding pipe connected to the inlet hole of the stripping container and having an inner diameter larger than a diameter of the plant stem; and an outer skin separation discharge hole placed near the outlet hole of the L5 stripping container. Furthermore, in the present invention, a configuration (claim 2) is preferable in which a crushing container is also provided in addition to the above configuration. That is, there is provided an apparatus for separating an outer skin of 20 a plant from parts other than the outer skin while a plant stem is washed and for crushing the parts other than the outer skin. The apparatus for separating the outer skin of the plant from the parts other than the outer skin has: a stripping container for the plant stem outer skin, the container being 25 provided with an inlet hole and an outlet hole to be opened 5 GJG : PAL ZPF063AU for passing through the plant stem in a lengthwise direction and having thereinside a plurality of nozzles for injecting pressurized water inwardly; a first plant feeding pipe connected to the inlet hole of the stripping container and 5 having an inner diameter larger than a diameter of the plant stem; an outer skin separation discharge hole placed near the outlet hole of the stripping container; a crushing container for the parts other than the plant stem outer skin, the crushing container being provided with an inlet hole and an LO outer hole to be opened for passing through the plant stem in a lengthwise direction, the crushing container having thereinside a plurality of nozzles for injecting pressurized water inwardly, the crushing container being connected to the outlet hole of the stripping container through a second plant L5 feeding pipe having an inner diameter larger than a diameter of the plant stem; and a crushed material discharge hole placed near the outlet hole of the crushing container. Furthermore, the present invention may have a configuration in which means for moving a plant stem is also ?0 provided. That is, there is provided an apparatus for separating an outer skin of a plant from parts other than the outer skin, wherein the plant feeding pipe has a notch portion in a part of an outer periphery thereof, and wherein the apparatus further has means for moving the plant stem in a 25 lengthwise direction of the feeding pipe, the means being 6 GJG : PAL ZPF063AU provided in the notch portion. Moreover, the present invention may have a configuration (claim 4) capable of being implemented when water resources are not in abundance, the configuration further having means 5 for collecting and filtrating discharged water discharged after injected toward the plant stem from the injection nozzles and flow feeding means for feeding purified water after filtration to the injection nozzles for circulation and reuse. 0 Furthermore, in order to suitably implement the present invention (claim 5), it is preferable that there be also provided with means for supplying, to the plurality of nozzles in the stripping container, first pressurized water having a pressure of 200 kilopascals to 500 kilopascals and means for 5 supplying, to the plurality of nozzles in the crushing container, pressurized water having a pressure equal to, or higher than, that of the first pressurized water. EFFECTS OF THE INVENTION 0 The present invention is an apparatus for separating the outer skin of a plant from parts other than the outer skin simply and easily in large quantities. Such an apparatus has not been concretely proposed in the past, and the following effects can be expected. ?5 Accordingly, the skin of a stem of a plant is unraveled 7 GJG: PAL ZPF063AU into pieces in a stripping container through an impact force of a high pressure water jet by means of a small amount of water to thereby separate the skin from the core, and the processing water after use is discharged with fibers of the 5 plant, is purified through a filter for removing dirt, and is reused, whereby the skin of the plant stem can be separated from the core thereof by use of a very small amount of water. In addition to this, the skin portion is washed for removing dirt and can be discharged with the fibers unraveled into 0 pieces, and the core portion can be taken out after the skin is stripped and the core is washed clean. These treatments can be performed simply and in large quantities. Furthermore, a crushing container may also be provided, and the core can be obtained as a crushed material which is easy to utilize. 5 Moreover, the present apparatus can be easily configured so as to circulate and reuse the water employed for a high pressure jet and thus can be implemented when water resources are not in abundance and the processing water must be saved. 0 BEST MODE FOR CARRYING OUT THE INVENTION Fig. 2 is a plan view of a stripping container or a crushing container of the present invention. The dotted line in the figure represents an outer wall of the stripping container or the crushing container. Fig. 3 is a perspective ?5 view of Fig. 2. Similarly, the dotted line in the figure 8 GJG :PAL ZPF063AU represents an outer wall of the stripping container or the crushing container. The stripping container or the crushing container is provided with an inlet hole and an outlet hole (not shown in Figs. 2 and 3) for passing through a plant stem 5 in a lengthwise direction. A plant stem 1 receives high pressure water jets 9 injected from a plurality of nozzles contained inside a stripping container 20 or a crushing container 30. Hence, dirt on the outer skin and water soluble materials other than plant 0 fibers are washed away, and the plant fibers are unraveled into pieces. In the stripping container, the injection pressure is adjusted to a pressure necessary and sufficient for plant skin fibers 2 to be blown toward an outer skin separation discharge 5 hole placed near the outlet hole of the stripping container. Preferably, this pressure is 200 kilopascals to 500 kilopascals. Stripping does not occur when the pressure is too low, and the fibers become too fine or are damaged when the pressure is too high. In the crushing container, the injection 0 pressure is adjusted to a pressure sufficient for the core of the plant to be crushed into a size and shape easy to handle and to be blown toward a crushed material discharge hole placed near the outlet hole of the crushing container. Preferably, the pressure is equal to, or higher than, that .5 supplied to the nozzles of the stripping container and is 300 9 GJG: PAL ZPF063AU kilopascals to 900 kilopascals. A known pressure pump, a known booster pump, or known pressure control means may be employed for means for supplying pressurized water having a pressure of 200 kilopascals to 500 kilopascals and for means for supplying, 5 to the plurality of nozzles in the crushing container, pressurized water having a pressure equal to, or higher than, that of a first pressurized water. Figs. 2 and 3 show an example in which four nozzles are provided as the nozzle inside the stripping container 20 or .0 the crushing container 30. However, the number of nozzles can be increased or decreased as appropriate. Furthermore, the angle of the jet hitting the plant stem is not limited to the angle shown in this figure. Fig. 4 is an illustration of a sector-shaped jet formed .5 by use of a slit-like nozzle serving as the nozzle for the high pressure water jet. The sector-shaped jet is suitable for stripping the outer skin. When such a slit-like nozzle is employed, the injection angle thereof must be adjusted according to the kind of the plant stem 1. For example, when .0 kenaf is stripped, an injection angle of 90* is suitable. Of course, a nozzle forming a circular jet, a straight jet, or the like, instead of the sector-shaped jet, may be employed. A nozzle for forming each jet shape is known. Fig. 1 is a diagram of a water circulation system of the 25 present invention and describes claim 4 of the present 10 GJG : PAL ZPF063AU invention. In order to circulate and reuse the water having already used for the high pressure jet, this configuration also has flow feeding means for feeding the water to the injection nozzles again. A "high pressure water jet A" in Fig. 5 1 represents processing in the stripping container. Similar to Fig. 1, Fig. 5 is a diagram of a jet water circulation-reuse system when the crushing container is also provided in the present invention (claim 2). In order to circulate and reuse the water having already used for the high pressure jet in the L0 crushing container, flow feeding means for feeding the water to the injection nozzles again is also provided. A "high pressure water jet A" in Fig. 5 represents processing in the stripping container, and a "high pressure water jet B" represents processing in the crushing container. In the water L5 circulation systems shown in Figs. 1 and 5, high pressure water is fed to the stripping container or the crushing container for reuse by means of a high water pressure supplying apparatus 7 (means for collecting and filtrating discharged water) provided with a filter 6. 20 Specifically, the plant stem 1 is separated into the plant skin fibers 2 and the plant core 4 in the stripping container, and the plant skin fibers 2 and the plant core 4 are discharged to a plant skin fiber container 3 and a plant core container 5, respectively. Furthermore, excess water in 25 the plant skin fiber container 3 and the plant core container 11 GJG : PAL ZPF063AU 5 is sent to the filter 6 therefrom for purification and is used as high pressure water again by means of the high pressure water supplying apparatus 7. Furthermore, in the crushing container, the plant core 4 5 is crushed through processing in the high pressure water jet B, and a crushed plant core 10 is discharged to a crushed plant core container 11. Furthermore, excess water at this time is sent to the filter 6 from the crushed plant core container 11 for purification and is used as high pressure water again by LO means of the high pressure water supplying apparatus 7. Fig. 6 is a perspective view illustrating the stripping container portion of the present invention. The apparatus is suitable for mass processing when a plant feeding pipe has notches in a part of the outer periphery thereof, as in 12 (a L5 feeding unit) in the figure, and means for moving the plant stem in the lengthwise direction of the feeding pipe is provided in the notches. The feeding unit in Fig. 6 has a configuration in which the plant stem is held between two rotation bodies at the ?0 notches of the feeding pipe to feed the stem downward by means of the frictional force at the outer periphery of the rotation bodies. Fig. 7 is a side view of Fig. 6. An outer skin separation discharge hole 13 is placed near the outlet hole of 25 the stripping container and is placed with an inclination 12 GJG: PAL ZPF063AU angle such that the plant skin fibers 2 slide down spontaneously. When a plant stem 1 is employed which is semi dried to the extent that the skin is dried and is cut into an appropriate length, continuous supply by means of the material 5 feeding unit 12 is facilitated. The plant skin fibers 2 (the outer skin), subjected to the high pressure water jet from the nozzles, slide down spontaneously and is discharged from the outer skin separation discharge hole 13, and the plant core 4 is discharged from a plant core discharge pipe 14. o Fig. 8 is a diagram illustrating a configuration (claim 2) in which the stripping container and the crushing container are connected. In Fig. 8, the plant skin fibers 2 (the outer skin) are discharged from the outer skin separation discharge hole 13 of the stripping container, and the crushed plant core 5 10 is discharged from the crushed material discharge hole 13 of the crushing container. The feeding pipe for the plant core is not necessarily vertical, which is the case in the examples of Figs. 7 and 8. However, the feeding pipe may be inclined or horizontal, so 0 long as the plant stem can be fed by means of 12 (the feeding unit). Furthermore, a configuration in which three or more sets of the stripping container and the crushing container are connected may be employed. 5 BRIEF DESCRIPTION OF THE DRAWINGS 13 GJG: PAL ZPF063AU Fig. 1 is a diagram for describing a water circulation system of the present invention.
