The present invention relates to a device for treating hydrolysis, and more particularly to a reactor for mixing and reacting a raw material with water in the hydrolysis device.

Hydrolysis refers to the reaction of a large molecule, which was originally a single molecule, into several ions or molecules by reacting with water during a chemical reaction. Hydrolysis can be achieved through a simple process of mixing with water, so hydrolysis has a wide range of applications including extraction and separation of the desired substance from the raw material. A hydrolytic treatment apparatus means an apparatus which is configured to efficiently and efficiently perform hydrolysis on a large amount of raw materials so that such hydrolysis can be used industrially or commercially.

In such a hydrolysis apparatus, hydrolysis can be practically carried out by reacting a raw material with water in a reaction vessel of a predetermined size.

The embodiments described herein relate to processing devices that utilize hydrolysis. However, it will be readily apparent to those skilled in the art that the principles and configurations of the described embodiments may be applied substantially equally to other processing devices that require mixing of the raw materials.

1 is a block diagram showing a hydrolysis apparatus according to the present invention. Referring to Fig. 1, the overall structure of the hydrolysis treatment apparatus of the present invention will be described below.

As already described in the background, the hydrolysis apparatus can be configured to decompose a given substance using hydrolysis. Such a hydrolytic treatment apparatus can be applied to various fields, and in particular, can be used to extract a desired substance from a raw material through a simple chemical reaction and treatment. More specifically, hydrolysis apparatuses are generally used for separating substances having a specific composition contained therein from a polymer compound.

Such a hydrolysis apparatus may include a feed pump 1, as shown in Fig. The feed pump 1 may be configured to transport the raw material to be hydrolyzed and the water required for hydrolysis to an external storage device or space. The feed pump 1 can transport various raw materials along with the water depending on the kind of the desired extract. In general, the feed pump 1 feeds raw material and water in a liquid state, but if necessary, the raw material may have a gel form with a high viscosity.

For example, among various extractable materials, the hydrolysis device can be applied to extract fatty acids. As shown in Scheme 1 below, the hydrolysis apparatus can perform hydrolysis to separate fattyacids from natural vegetable oil triglycerides. Referring to Reaction Scheme 1, the fat raw material is generally composed of one molecule of glycerin and three molecules of fatty acid and can be decomposed into glycerol and fatty acid which is an aliphatic monobasic acid by hydrolysis.

[Reaction Scheme 1]

In addition, the fatty acid may have a detailed chemical structure as shown in Formula 1 below.

[Structural formula 1]

The extracted fatty acid is used as a raw material for various chemical products such as grease, soap, cosmetics, paints and the like, and thus has a considerably wide range of application. Therefore, when the hydrolysis apparatus of the present invention is applied for fatty acid extraction, the feed pump 1 can transfer the oil with the water as a raw material. As described above, in addition to the examples of such fatty acids, various raw materials corresponding to various extracts can be supplied through the feed pump 1.

The hydrolysis apparatus may also comprise a reactor 2 connected to the feed pump 1. The reactor 2 can be supplied with raw material and water through a flow path such as a pipe from the feed pump 1 as shown, and can be configured to react the raw material and water with each other so as to generate hydrolysis. More specifically, the reactor 2 can be configured to produce conditions suitable for hydrolysis to occur in the raw materials and water contained therein, such as temperature and pressure, and the like. In addition, the reactor (2) may be configured to mix the raw material and water to facilitate the reaction between the water and the raw material. Furthermore, the reactor 2 can be connected to the circulator 3, which is configured to circulate a mixture of the raw material and water contained therein. The circulator 3 can be configured to discharge the mixture of raw material and water, which has undergone hydrolysis to some extent, from the reactor 2 and supply it to the reactor 2 again, as shown in Fig. By such circulation, the raw material and water can be mixed and contact more uniformly, and the hydrolysis can be promoted. For the above-described operation, the circulator 3 may be composed of a circulation flow path connected to the reactor 2 and a pump disposed in the circulation flow path, and may have another configuration capable of mixing raw material and water.

Furthermore, in the hydrolysis treatment apparatus of the present invention, the extractor 4 can be configured to extract the intended substance, for example, fatty acid, from the hydrolysis product discharged from the reactor 3. More specifically, the extractor 4 performs processes such as separation, curing, and condensation on the product, thereby extracting only the desired substance. Further, although not shown, additional processors configured to distill, purify and concentrate the extract may be connected to the extractor 4 to increase the purity of the extract. The thus treated extract can be discharged to the outside for storage via the discharge pump 5. The effluent pump (5) can also discharge the byproducts other than the extract produced by the hydrolysis to the outside for disposal.

As described above, in order to improve the hydrolysis performance in the reactor 2, uniform contact between the raw material and water is required, and in order to achieve such uniform contact, the raw material and water need to be uniformly mixed with each other . For this reason, in the hydrolytic treatment apparatus according to the present invention, the reactor 2 is improved to mix the raw material and water more uniformly, and such a reactor 2 is described in more detail below with reference to the related drawings.

2 is a side sectional view showing in detail the reactor of the hydrolysis apparatus according to the present invention, and Fig. 3 is a perspective view showing in detail the reactor of the hydrolysis apparatus according to the present invention. 4 is a plan view of the reaction tank of the reactor showing the main and auxiliary actuator in detail.

Referring to FIGS. 2 and 3, the reactor 2 may include a reaction tank 201 of a predetermined size. The reaction tank 201 may be in the form of a container, which, as shown in the figure, is opened at an upper portion thereof to accommodate the first to third stirrers to be described later and to permit their operation, and to form an inner space of a predetermined size. The reaction tank 201 can accommodate a predetermined amount of raw material and water to be hydrolyzed in an internal space formed by being supplied from the supply pump 1. [ In addition, the reaction tank 201 may be configured to create a suitable environment therein so that hydrolysis can be smoothly generated in the raw materials and water contained therein. For example, the reaction tank 201 may be configured to perform pressurized hydrolysis. In this case, the temperature in the reaction tank 201 may be maintained at 180 to 200 ° C, and the pressure may be 10 to 15 kg / Cm < 2 >. Although not shown, the reaction tank 201 may further include various peripherals for forming such temperature and pressure, i.e., heating and pressurizing devices. Also, the reaction tank 201 may have the form of an entirely closed container closed at the top to maintain the generated temperature and pressure.

The reactor 2 may also include a plurality of agitators configured to mix the raw material and water to facilitate hydrolysis. First, the reactor 2 may have a first stirrer 250, 260 disposed above the reaction tank 201. Precisely, the first stirrers 250 and 260 can be positioned above the inner space of the reaction tank 201. The first stirrers 250 and 260 may be disposed at a central portion of the upper portion of the reaction tank 201. More specifically, the first stirrers 250 and 260 may include a motor 250 and a blade 260 rotatably coupled to the motor 250. The blade 260 extends and is oriented parallel to the bottom of the reaction tank 201, as shown, and can be driven to rotate by the motor 250. That is, the blade 260 may be configured to rotate within a horizontal plane that is parallel to the bottom or the ground and that is located at the top of the reaction tank 201. By the rotation of the blade 260, the first agitator can uniformly mix a part of the raw material and water present in the upper part of the reaction tank 201.

In addition, the reactor 2 may include a second agitator 240 disposed adjacent to the inner circumferential surface of the sidewall of the reaction tank 201. That is, the second stirrer 240 may be disposed at the edge of the inner space of the reaction tank 201. The second stirrer 240 is a stirring rod extending vertically along the inner circumferential surface of the sidewall of the reaction tank 201, that is, horizontally to a central axis of the reaction tank 201 241). Also. The second stirrer 240 may include a connecting rod 242 that extends in the radial direction of the reaction tank 201, that is, horizontally and connects the stirring mechanism 241 with a driving mechanism described later. The second agitator 240 and more specifically the stirring rod 241 can revolve along the inner circumferential surface of the reaction tank 201 while maintaining a predetermined gap on the inner circumferential surface thereof by the driving mechanism. That is, the stirring rod 241 of the second stirrer 240 is pivoted about the center axis of the reaction tank 201, and accordingly, a predetermined circular shape It can revolve substantially along the trajectory. By the motion of the stirring rod 241 described above, the second stirrer 240 can uniformly mix the raw material and water present on the side of the inner space of the reaction tank 201, that is, near the inner circumferential surface or at the edge of the inner space . Since the connection rod 242 also extends across the upper part of the reaction tank 201, the first and second stirrers 250 and 260 are rotated together with the stirring rod 241 by the driving mechanism, And water can be mixed more uniformly. The second stirrer 240 may include a pair of stirring rods 241 and connecting rods 242 disposed symmetrically with respect to each other about the center axis of the reaction tank 201. As shown in FIG. By the pair of rods 241 and 242, the mixing of the raw material and water present on the side of the inner space of the reaction tank 201 can be performed more efficiently.

As mentioned above, the reactor 2 may include a driving mechanism for driving or moving such first and second stirrers in the reaction tank 201 in a predetermined direction.

First, the driving mechanism may include a first driving mechanism 220, 230 configured to rotate the first and second stirrers 250, 260, 240 in the reaction tank 201. The first driving mechanisms 220 and 230 may include a driving motor 220 and a driving shaft 230 connected to the driving motor 220 to rotate. The first drive mechanisms 220 and 230 are coupled to a fixed rod 210 disposed on the reaction tank 201 and the fixed rod 210 can be coupled to a structurally stable external structure. The first and second agitators 250, 260 and 240 connected to the first driving mechanism as well as the first driving mechanisms 220 and 230 can be stably installed and operated in the reaction tank 201, have. Also, as shown in the drawing, the fixing rod 210 and the first driving mechanisms 220 and 230 are provided to prevent the first and second stirrers 250, 260 and 240, which are moving, from being properly spaced from the wall surface of the reaction tank 201, May be disposed on the central portion of the reaction tank 201, specifically on the central axis thereof.

More specifically, the first agitators 250 and 260 may be coupled to the ends of the drive shaft 230. Also, the connecting rod 242 of the second stirrer 240 may be connected to the driving shaft 230. Accordingly, when the driving shaft 230 is rotated, the connecting rod 242 of the second stirrer 240 rotates, and the stirring rod 241 connected to the driving shaft 230 rotates along the predetermined trajectory, It can be turned near the inner peripheral surface. In addition, by rotating the drive shaft 230, the first agitators 250 and 260 coupled thereto can be rotated in a predetermined direction. Accordingly, mixing of water and raw material can be promoted by this rotation which is performed additionally to the rotation of the blade 260. According to one embodiment of the present invention, the blade 260 can rotate in the same direction as the rotation direction of the drive shaft 230. [ Thus, a stronger rotational force can be generated, which can be advantageous when mixing a highly viscous raw material with water. On the other hand, according to another embodiment of the present invention, the blade 260 can rotate in a different direction from the drive shaft 240. [ In this case, irregular flows such as eddy currents may be generated around the first agitators 250 and 260 due to different rotational directions, so that uniform mixing of water and raw materials can be performed. As described above, since the second agitator 240 is directly coupled to the drive shaft 230 and rotates in the same direction, the blade 260 selectively rotates in the same direction as the second agitator 240 and in the other direction Lt; / RTI > Therefore, when the second agitator 240 rotates in the same direction as the blade 260, a stronger rotational force can be generated. In addition, when the second agitator 240 rotates in a direction different from that of the bleeder 260, a strong vortex as a whole may be generated over the upper and side portions of the reaction tank 201.

In addition, the driving mechanism may include a second driving mechanism 231, 232 configured to move the first and second stirrers 250, 260, 240 in a vertical direction in the reaction tank 201, that is, . Various additional devices may be used to move the first and second agitators 250.260 and 240 in the vertical direction, but the drive shaft 230 to which the agitators 250.260 and 240 are connected performs such a function May be advantageous for structural simplification. Accordingly, the drive shaft 230 can be configured to extend or contract in the vertical direction as the second drive mechanism. Also, various similar mechanisms may be applied to extend and retract the drive shaft 230, and in the embodiment of the present invention, a hydraulic or pneumatic mechanism capable of effectively performing the intended function can be employed. The second driving mechanisms 231 and 232 or the driving shaft 230 may be composed of a cylinder 232 and a movable rod or a plunger 231 movably coupled to the cylinder 232. The plunger 231 can be extended or retracted from the cylinder 232 in the vertical direction by the driving force generated in the cylinder 232.

More specifically, since the plunger 231 is configured to be movable as described above, the first agitators 250 and 260 can be coupled to the end of the plunger 231. Also, for the same reason, the connecting rod 242 of the second stirrer 240 may also be directly connected to the plunger 231. Accordingly, when the plunger 231 is extended, the first stirrers 250 and 260 can be moved vertically from the upper portion of the reaction tank 201 toward the middle portion thereof. For this reason, uniform mixing of the raw material and water can be achieved not only in the upper portion of the reaction tank 201 but also in the central portion thereof by the first stirrers 250 and 260. The second agitator 240 can also be vertically moved from the upper portion of the edge of the reaction tank 201 toward the middle portion of the edge by the extension of the plunger 231, Water can be uniformly mixed. Further, by repeatedly extending and contracting the plunger 231, the first and second stirrers 250, 260, and 240 are reciprocated in the vertical direction in the reaction tank 201, and a more uniform mixture of water and raw material . ≪ / RTI >

Meanwhile, the first and second stirrers 250, 260 and 240 may mix water and raw materials in most regions of the reaction tank 201, but the mixing at the center of the inner space of the reaction tank 201 is performed by these stirrers 250, 260, 240). ≪ / RTI > Therefore, the reactor 2 may further include a third agitator 275 configured to mix the raw material and water present in the center of the reaction tank 201. The third stirrer 275 may be provided at the end of the second stirrer 240, precisely at the end of the stirrer rod 241 of the second stirrer 240, as shown. The third agitator 275 may be disposed adjacent to the inner circumferential surface of the sidewall of the reaction tank 201, that is, at the edge of the inner space of the reaction tank 201, like the stirring rod 241. In addition, the third stirrer 275 may have a rod-shaped body that is elongated like the stirring rod 241 so that the surrounding water and the raw material can be mixed by a predetermined movement. The third agitator 275 may further include a plurality of blades 277 extending from the body in the radial direction to more effectively perform the mixing of the water and the raw material. These blades 277 may be spaced apart from each other by a predetermined distance in the longitudinal direction of the body of the third agitator 275 so as to allow mixing in a wider area. The third stirrer 275 can be coupled to the second stirrer 240 by the hinge 270 and thus can be pivoted or rotated about the hinge 270. [ The third agitator 275 swings between the inner circumferential surface of the reaction tank 201 and the middle portion of the reaction tank 201 as indicated by the dotted line and the arrow . In other words, the third stirrer 275 can rotate to rotate from the inner circumferential surface of the reaction tank 201 to the center thereof and rotate again from the center portion to the inner circumferential surface again, and these rotations can be repeatedly performed . The movement of the third agitator 275 can uniformly mix water and raw materials between the inner peripheral surface and the middle portion of the reaction tank 201. Also, since the third agitator 275 extends long from the second agitator 240, it can reach the bottom of the reaction tank 201, that is, the bottom thereof, as shown in FIG. Water and raw materials can be uniformly mixed. Further, as shown, the reactor 2 may include a pair of second agitators 240, so that the ends of the second agitators 240 are also connected to each other And a pair of third stirrers 275 symmetrically coupled to each other.

As discussed above, the third agitator 275 is directly connected to the second agitator 240 so that the second agitator 240, which is performed by the first and second driving mechanisms 220, 230, 231, 232 in addition to its own swing motion 240). ≪ / RTI > More specifically, when the driving shaft 230 of the first driving mechanism rotates, the stirring rod 241 of the second stirrer 240 can swing around the inner peripheral surface of the reaction tank 201 along a predetermined trajectory. Accordingly, the third agitator 275 connected to the agitating rod 241 can similarly swing along the same locus, and the water and the raw material can be more uniformly formed near the inner circumferential surface of the reaction tank 201 together with the second agitator 240 Can be mixed. Since the second agitator 240 and the third agitator 275 are directly coupled to the drive shaft 230 and rotate in the same direction, the second and third agitators 240 and 275 are arranged in the same direction as the blades 260 of the first agitator. Direction or in other directions. If rotated in the same direction as the blade 260, the added third agitator 275 can generate a stronger rotational force, and when rotated in a direction different from that of the blade 260, . Further, when the plunger 231 of the second driving mechanism is extended and retracted, the third agitator 275 can reciprocate vertically at the edge of the reaction tank 201 together with the second agitator 240, (2) can be further improved.

Various actuators can be applied for the swing motion of the third agitator 275. For example, a motor or hydraulic / pneumatic devices directly connected to the hinge 270 and configured to rotate the axis of the hinge 270 directly may be used as the actuator. However, in the embodiment of the present invention, the reactor 2 can employ an actuator having a simpler, lower manufacturing cost and higher operating accuracy and efficiency. These actuators are described in more detail below with reference to Figures 2-4. In addition to the previously referenced Figures 2 and 3, Figure 4 is a top view of the reaction tank of the reactor showing the first and second actuators in detail.

First, the third stirrer 275 may include a first actuator configured to apply a predetermined driving force to the body of the reaction tank 102 toward the center of the reaction tank 102 for swing motion. The first actuator includes a first magnet 280 provided at the body end of the third stirrer 275 and a plurality of second magnets 280 provided on the bottom of the reaction tank 201 so as to face the first magnet 280. [ (290). The first magnet 280 is opposed to the first end of the body of the third stirrer 275 coupled to the second stirrer 240 and the first magnet 280 is opposed to the bottom of the reaction tank 201, 2 < / RTI > The second magnets 290 may be disposed at the bottom-up positions of the reaction tank 201 corresponding to predetermined positions where the third stirrer 275 is disposed during the swing motion, and may be spaced apart from each other by a predetermined distance . 4, the second magnets 290 move along the locus P on the bottom of the reaction tank 201 aligned with the trajectory of the turning movement of the third stirrer 275, And may be disposed at predetermined intervals along the circumferential direction of the bottom portion. The first and second magnets 280 and 290 are configured to have the same polarity and when they are aligned with each other, a repulsive force may act between the magnets 280 and 290. More specifically, when the third stirrer 275, precisely its first magnet 280, is aligned with the second magnet 290 while the third stirrer 275 is pivoting, relative repulsive force is applied to the first magnet 280 ) And the second magnet 290, respectively. However, the second magnet 290 is fixed to the bottom of the reaction tank 201 so as not to move, while the first magnet 280 is fixed to the body of the rotatable third agitator 275. Therefore, the first magnet 280 and the third stirrer 275 can be pushed radially inward of the reaction tank 201, that is, toward the center thereof, by the relatively applied repulsive force. For this reason, as indicated by the arrow (A1 in Fig. 4) in Fig. 2, the third stirrer 275 can rotate around the hinge 270 to the center of the reaction tank 201, It is possible to return while rotating toward the inner peripheral surface of the reaction tank 201 again by gravity. In addition, since the plurality of second magnets 290 are disposed on the bottom of the reaction tank 201, these rotary motions can be repeatedly performed while the third stirrer 275 is turning.

In the swing motion of the third stirrer 275 described above, since the third stirrer 275 is disposed adjacent to the inner peripheral surface of the reaction tank 201 for the first time, when it is returned from the central portion of the reaction tank 201, May collide with the inner circumferential surface. Therefore, the reactor 2 needs to be configured to control excessive rotation of the third agitator 275. For this reason, the third agitator 275 may further include a second actuator configured to catch the body returning from the central portion of the reaction tank 201 toward the inner peripheral surface. The second actuator may apply a restraining force to the body when the body of the third agitator 275 to be returned is stopped at a predetermined position. 4, the second actuator may be composed of a plurality of third magnets 291 provided on the bottom of the reaction tank 201 so as to face the first magnet 280 . The third magnets 291 are arranged along the locus P on the bottom of the reaction tank 201 aligned with the trajectory of the pivotal motion of the third stirrer 275 as well as the second magnets 290, And can be disposed at predetermined intervals along the circumferential direction. The third magnets 291 may also be disposed between the second magnets 290 so that the second and third magnets 290,291 ) Can be arranged alternately. These third magnets 291 may be configured to have different polarities from the first magnets 280, unlike the second magnets 290, and when aligned with one another, the first and third magnets 290 280, and 291, respectively. More specifically, as shown in FIG. 4, when the third stirrer 275 and the first magnet 280 are aligned with the second magnet 290 while the third stirrer 275 is pivoting, And can be rotated toward the center of the reaction tank 201, as indicated by the arrow A1. During this rotation, as indicated by the arrow A2, the third stirrer 275 pivots with the second stirrer 240 at a predetermined distance, and at the same time, as indicated by the arrow A3, To the third magnet (291). When the third stirrer 275 approaches the third magnet 291, the third stirrer 275 moves to the position of the third magnet 291 by the attractive force acting between the first and third magnets 280, That is, the win position adjacent to the inner circumferential surface of the reaction tank 201. In addition, the in-situ third agitator 275 may be stopped and constrained to the original position to prevent further rotation by the applied force. Therefore, the third agitator 275 can avoid collision with the inner circumferential surface of the reaction tank 201 due to excessive rotation, thereby preventing noise generation and breakage. The driving force of the driving shaft 230 of the first driving mechanism which is greater than the attractive force between the first and third magnets 280 and 291 causes the third stirrer 275 to rotate about the second actuator 290, Can be pivoted toward the adjacent second magnet 290 and can repeat the operations according to the arrows A1-A3 described above, as indicated by arrow A4, away from the constraint.

Further, when a large amount of raw material and water are stored in the reaction tank 201, particularly when a raw material having a high viscosity is stored, a repulsive force between the first and second magnets 280, 275 may not be generated. Accordingly, the third agitator 275 may further include an auxiliary actuator that initially provides an additional driving force to the body of the third agitator 275. Such an auxiliary actuator may comprise a motor or a pneumatic / hydraulic device directly coupled to the hinge 270 as described above.

Further, as shown in FIG. 5, the second magnet 290 can be oriented obliquely toward the center of the reaction tank 201. The second magnet 290 is disposed in the reaction tank 201 so that the first magnet 280 and the third stirrer 275 are connected to the reaction tank 201, It is possible to rotate with a stronger force toward the center of the rotor. A wedge member 298 may be interposed between the bottom of the second magnet 290 and the bottom of the reaction tank 201 to maintain the tilted orientation of the second magnet 290 as shown. Also, like the second magnet 290, the third magnet 291 can also be oriented obliquely toward the center of the reaction tank 201. As shown, the third stirrer 275 swings about the hinge 270, so that the third stirrer 275 can approach a slightly inclined state when returning to the original position. Thus, the upper surface of the third magnet 291 oriented in an inclined orientation can directly face the lower surface of the first magnet 280 of the third stirrer 275, and thus the third stirrer 295 can be directly held A strong attraction force can be effectively applied. Similar to the second magnet 290, the same wedge member 298 can also be applied to the third magnet 291 to maintain this tilted orientation.

On the other hand, as compared with liquid water, gaseous water has a larger surface area, and therefore can make uniform contact with the raw material. In addition, gaseous water has higher fluidity than liquid water, so that it can be more easily mixed with the raw material. Therefore, a more efficient hydrolysis reaction can be induced when the gaseous water is mixed with the raw material. For this reason, the reactor 2 may further include a feeder configured to supply gaseous water into the reaction tank 201. For the hydrolysis reaction, the feeder can additionally supply gaseous water after the raw and liquid water has already been supplied to the reaction tank 201, and on the other hand, Only gaseous water may be supplied. The feeder will be described in more detail with reference to FIGS. 1, 2 and 6 as follows. In addition to Figures 1 and 2, Figure 6 is a cross-sectional view of the feeder taken along line A-A of Figure 2.

As described above, the second stirrer 240 includes a connecting rod 242 extending in the radial direction and a stirring rod 241 extending vertically from the connecting rod 242, whereby the raw material in the reaction tank 201 as a whole It can have a structure that can be contacted. Thus, in an embodiment of the present invention, the feeder may be installed in the second agitator 240. As shown in FIG. 6, this feeder includes a flow path 243 for flowing water in a gaseous state and an opening 244 for supplying gaseous water transferred through the flow path 243 to the raw material . The flow path 243 can be continuously formed along the entire second agitator 240, that is, along the agitating rod 241 and the connecting rod 242. The flow path 243 may be continuously extended to the second agitator 240 and may be disposed outside the reaction tank 201 so as to receive water in the liquid state or the gaseous state from the outside. And may be connected to a predetermined supply device. Furthermore, the opening 244 can be made of a nozzle so as to apply a predetermined pressure to the gaseous water to be injected, so that gaseous water can be mixed with the raw material more efficiently.

As shown in Fig. 1, the feeder may include a vaporizer 6 disposed outside the reaction tank 201. The vaporizer 6 can supply liquid water from the supply pump 1 and convert it into a gaseous state and supply it to the flow path 243 in the reaction tank 201 through a separate flow path. The water in the liquid state can be supplied in the form of mist composed of small water particles without heating and on the other hand the water can be supplied in the form of steam having high temperature and pressure by heating the water. The steam is preferably adapted to create an environment suitable for hydrolysis due to the high temperature and pressure, so that the feeder is preferably configured to supply steam.

On the other hand, the feeder may have a separate heating mechanism disposed in the flow path 243 instead of the vaporizer 6. [ More specifically, the heating mechanism may include a heater 245 disposed in the flow path 243 basically, as shown in FIG. That is, the heater 245 can extend along the second stirrer 240 and the drive shaft 230, precisely along their inner circumferential surfaces. Further, in order to protect the heater 245, a coating 246 may be provided in the flow path 243. [ The sheath 246 entirely encloses the heater 245, as shown, thereby isolating the heater 245 from the water being supplied. The water supplied to the flow path 246 by this heating mechanism can be heated and converted into gaseous steam and supplied into the reaction tank 201 through the opening portion 244. [ Further, such a heating mechanism can be applied to the feeder together with the vaporizer 6. [ The gaseous water supplied from the vaporizer 6 can be condensed into liquid while flowing along the flow path 246. However, when the heating mechanism is applied, the gaseous water supplied from the vaporizer 6 is continuously heated by the heating mechanism, so that the reaction tank 201 is maintained in the gaseous state at high temperature and high pressure, As shown in FIG.

Further, as described above, the second stirrer 240 has a structure capable of entirely contacting the raw material, so that the feeder may supply liquid water instead of gaseous water. That is, the liquid water can flow from the outside through the flow path 243 and can be supplied through the opening 244. [ In this case, the feeder may still allow uniform mixing of the raw material and water.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
