[Technical field]

[0001] The present invention relates to a mixing and melting device for mixing and melting materials. [Background technology]

[0002] In recent years, the concentration of carbon dioxide in the atmosphere has increased, and climate change such as global warming has become a problem. In order to suppress environmental abnormalities such as global warming and reduce the use of fossil resources that are in danger of being depleted, the use of biomass, a renewable resource that effectively utilizes biotechnology, has been promoted. Regarding the production of biomass materials, a technology has been disclosed for forming a wood-based composite resin material from a wood-based filler material, a lubricant, a thermoplastic resin raw material, and an oxygen modifier (see Patent Document 1).

[0003] [Patent Document 1] Patent No. 4598194 Summary of the Invention [Problem to be solved by the invention]

[0004] In the mixing and grinding device described in Patent Document 1, there is no mention of adjusting the amount of fluid inside the mixing vessel. Therefore, in order to add water before fusion, it must be added to the material before it is fed, and there is a possibility that the material may adhere to the feeding path during feeding, resulting in poor feeding. In addition, water cannot be added after fusion, and the fused material cannot be cooled before being discharged. As a result, the fused material cannot be discharged properly, and the fusion agent remains in the fusion furnace, which increases the frequency of cleaning and reduces operational efficiency.

[0005] In view of the above-mentioned problems, an object of the present invention is to provide a mixing and melting device capable of adjusting the amount of fluid in a mixing container. [Means for solving the problem]

[0009] The mixing and melting apparatus of this embodiment will be specifically described with reference to the drawings.

[0010] Fig. 1 is a front view showing a mixing and melting device 1 according to an embodiment of the present invention. Fig. 2 is a partially enlarged view showing a blade member 10 and a supply screw 12 in the mixing and melting device 1 according to the embodiment. Fig. 3 is a skeleton block diagram showing the entire system of the mixing and melting device 1 according to the embodiment.

[0011] The mixing and melting device 1 of this embodiment includes a machine base 2, a cylindrical mixing container 3 arranged horizontally on the machine base 2, a motor 8 as a drive source installed on the machine base 2, a rotating shaft 5 rotated by the motor 8, a plurality of blade members 10 arranged on the rotating shaft 5 in the mixing container 3, a material input section 14 for inputting materials, and a supply screw 12 for supplying the materials inputted to the material input section 14 to the mixing container 3. The material input section 14 has an upper hopper 14a and a material inflow section 14b located below the hopper 14a and sandwiching an opening / closing section 15 therebetween.

[0012] The motor 8 is driven by a power source (not shown). The motor 8 transmits a driving force to the rotating shaft 5, and rotates the blade member 10 and the supply screw 12 via the rotating shaft 5. The motor 8 can control the number of rotations so that the peripheral speed of the tip of the blade member 10 is within a range of 5 m / s to 50 m / s. The output shaft of the motor 8 and the rotating shaft 5 are connected by a slippery V-belt 7 so that when a sudden change in load torque occurs in the rotating shaft 5, the load torque is not transmitted to the motor 8. The output shaft of the motor 8 and the rotating shaft 5 may be connected via a brake, a clutch, or the like. The rotating shaft 5 may be formed coaxially with the output shaft of the motor 8.

[0013] The rotating shaft 5 is supported horizontally by bearings 4, 4, and is disposed coaxially through the center of the mixing vessel 3. One end of the rotating shaft 5 is in rotational communication with a motor 8 serving as a drive source via a pulley 6 and a V-belt 7. The rotating shaft 5 is hollow with a small diameter hole formed in the axial center for supplying cooling water, and rotary joints 9 are provided on both ends thereof, so that cooling water is supplied axially into the interior of the rotating shaft 5 through the rotary joints 9.

[0014] As shown in Fig. 2, a total of six blade members 10a-10f, each having a rectangular cross section and an overall rectangular shape, are provided on the outer periphery of the rotating shaft 5 disposed penetrating through the mixing vessel 3, at intervals of 180 degrees in the circumferential direction of the rotating shaft 5 and spaced apart in the axial direction. As shown in Fig. 2, the thickness of the blade members 10a-10f is formed so that about 40% of the outer periphery is thicker than the inner periphery, allowing the materials to be mixed, crushed, and melted effectively.

[0015] Of these, the blade members 10a and 10f at both ends in the axial direction are fixed to the outer periphery of the rotating shaft 5 at an inclination of about 15 degrees from the tip to the base of the blade member 10 so that their front edges come into sliding contact with the inner surfaces of the vertical walls 11, 11 at both ends of the mixing vessel 3 with almost no gap when rotating clockwise as viewed from the right side of Figure 1.

[0016] The four blade members 10b, 10c, 10d, and 10e in the middle section are fixed to the outer circumferential surface of the rotating shaft 5 in a staggered pattern, inclined from the tip to the base of each blade, and are arranged so that their leading edges face both ends of the mixing vessel 3 during rotation. That is, the four blade members 10b, 10d, 10c, and 10e are opposed to each other in the axial direction as shown in Fig. 2, and are arranged on the rotating shaft 5 at a mounting angle (angle with respect to the circumferential direction) of 15 degrees so that the opposing distance between them narrows in the rotation direction.

[0017] In addition, in the direction of the rotating shaft 5, the motor 8 side of the mixing vessel 3 is the material supply section 3a, and the opposite side of the motor 8 is the material mixing section 3b. A spiral supply screw 12 formed on the outer periphery of the rotating shaft 5 is housed in the material supply section 3a. The material supply section 3a surrounds the supply screw 12. A material input section 14 is provided above the material supply section 3a. After the material is input into the material input section 14, an opening / closing section 15 is provided that can be closed airtightly during mixing, grinding, and melting. In addition, a pair of balance wheels 16 are provided on both sides of the blade member 10 and the supply screw 12 of the rotating shaft 5 to ensure smooth rotation.

[0018] The material mixing section 3b surrounds the blade member 10 fixed to the rotating shaft 5. The material mixing section 3b has a material supply section 3a on the upstream side. The material fed into the material supply section 3a is moved to the material mixing section 3b by a supply screw 12 in the material supply section 3a. The material is mixed in the material mixing section 3b by the blade member 10. It is to be noted that the material may be fed from above the material mixing section 3b without using the material supply section 3a and the supply screw 12.

[0019] 3, a continuous water passage 24 is formed in the peripheral wall of the mixing vessel 3 and in the center of the rotating shaft 5, and a cooling section 22 is configured that can cool the peripheral wall of the mixing vessel 3 and the rotating shaft 5 by circulating cooling water. The cooling section 22 cools the water in a cooling tower 23, and returns the water to the cooling tower 23 to cool the mixing vessel 3, the rotating shaft 5, etc.

[0020] In addition, a discharge port lid 17 for removing the molten material is provided on the bottom wall of the mixing vessel 3. The discharge port lid 17 is rotatably supported by a shaft 18, and the shaft 18 is connected to rotary cylinders 19, 19 so as to be able to be opened and closed.

[0021] In addition, the collars 20, 20 on both sides shown in Figure 2 are for sending air to the mixing vessel 3, and the continuous grooves on each end are composed of right-handed and left-handed spiral grooves so that air is sent to the mixing vessel 3 by the rotation of the rotating shaft 5.

[0022] The control panel 21 is also connected to the motor 8 via a connection cable, and the load torque of the main shaft is continuously input as an electric signal from the motor 8. The control panel 21 may control the timing of opening and closing the discharge port lid 17 of the mixing vessel 3 based on the change in the load torque acting on the main shaft of the motor 8 according to the mixed and ground state of the material in the mixing vessel 3 and the drying state, thereby removing the mixed and ground material.

[0023] A method for producing a fused material using the mixing and melting device 1 as the mixing and melting device of this embodiment will be described. A user puts materials into the mixing container 3 of the mixing and melting device 1 through an opening (not shown), drives the motor 8, and rotates the rotating shaft 5, the blade member 10, and the supply screw 12 to finely crush the materials. The size of the crushed particles is preferably about 2 to 7 mm. The crushing step is not performed when the material is simply put in after being crushed in advance by another device.

[0024] Subsequently, the motor 8 is driven to rotate the rotary shaft 5, the blade member 10, and the supply screw 12, thereby mixing the pulverized materials. The rotation speed of the rotary shaft 5 is preferably set to 500 rpm or more.

[0025] In addition, in the production of the fusion material of this embodiment, additives for compatibilization may not be used. By not using additives, environmental friendliness is improved. Furthermore, in this embodiment, it is preferable to supply a fluid to the material by the fluid supply unit 30. By supplying a fluid, the internal pressure can be increased in a later process. The fluid may be supplied to the inside of the mixing container 3 in advance, or may be supplied to the inside of the mixing container 3 during operation. Here, the fluid used is air, tap water, cold water, warm water, or hot water. Therefore, the mixing and melting device 1 of this embodiment can appropriately adjust the pressure, temperature, humidity, and the like in the mixing container 3. In addition, for example, when air or tap water is used, it can be operated at low cost, when cold water is used, it is possible to cool the inside of the mixing container 3, and when warm water or hot water is used, it is possible to warm the inside of the mixing container 3.

[0026] Next, the motor 8 is driven to rotate the rotating shaft 5, the blade member 10, and the supply screw 12. When the blade member 10 is rotated at high speed, the temperature inside the mixing vessel 3 becomes high, at 100°C or higher, due to the movement of the materials themselves and friction caused by the materials colliding with each other and shearing them. After that, steam is generated from the fluid, pressure is applied inside the mixing vessel 3, and each material melts.

[0027] Next, the motor 8 is driven to rotate the rotating shaft 5, the blade member 10, and the supply screw 12 to advance the reaction of the materials. As the reaction progresses, the materials are integrated. At the same time, the fluid is vaporized and discharged to the outside from an outlet (not shown) of the mixing vessel 3. Therefore, the inside of the mixing vessel 3 becomes dry, and a fusion product from which moisture and the like have been removed is obtained.

[0028] The resulting fusion product is a new material in which multiple materials with different melting points are uniformly fused at the molecular level, and since it can be molded by injection, extrusion, blowing, pressing, etc., it can be used for a variety of purposes.

[0029] In addition, the method for producing a fusion material of this embodiment is performed in less than 1800 seconds. Usually, the more heat input a material receives, the more severe its deterioration becomes. In the method for producing a fusion material of this embodiment, heat is not applied from the outside, and the time for which heat is applied to the material is short. Therefore, the fusion material produced by the method for producing a fusion material of this embodiment is less likely to deteriorate and can maintain its strength. In addition, since the fusion material produced by the method for producing a fusion material of this embodiment is less likely to deteriorate, the completed fusion product can be reused.

[0030] Next, the fluid supply unit 30 of this embodiment will be described.

[0031] Fig. 4 shows a front view of the fluid supplying section 30 of the mixing and melting apparatus 1 of the first embodiment. Fig. 5 shows a side view of the fluid supplying section 30 of the mixing and melting apparatus 1 of the first embodiment.

[0032] The fluid supply unit 30 of the first embodiment is connected to the material input unit 14 of the mixing and melting apparatus 1. The fluid supply unit 30 has a supply pipe 31, a flow rate control unit 32 installed in the middle of the supply pipe 31, and a fluid supply member 33 installed at the tip of the supply pipe 31.

[0033] Supply pipe 31 is a pipe through which a fluid flows, such as air, tap water, cold water, warm water, hot water, or cooling water cooled by cooling tower 23 shown in Fig. 3. The amount of fluid flowing through supply pipe 31 is adjusted by flow rate control unit 32. Flow rate control unit 32 is installed midway through supply pipe 31, and may control the flow rate of the fluid passing through supply pipe 31 by, for example, adjusting the rotation angle of a valve.

[0034] The fluid supplying member 33 of the first embodiment is installed in a hole 14b1 formed in the material inlet portion 14b. In the mixing and melting device 1, at least one hole 14b1 is formed in the material inlet portion 14b, and the fluid supplying member 33 is installed therein. A plurality of holes 14b1 may be formed in the material inlet portion 14b, and a plurality of fluid supplying members 33 may be installed therein. The plurality of holes 14b1 may be formed in the hopper 14a.

[0035] The fluid supply member 33 of this embodiment has a plurality of holes 14b1 arranged in twos below the material inlet section 14b, and a fluid supply member 33 is installed in each of the plurality of holes 14b1. The number of holes 14b1 may be two or more. The plurality of holes 14b1 may be arranged vertically or diagonally. Furthermore, the lines connecting the plurality of holes 14b1 without intersecting each other may form a square, rectangle, trapezoid, or regular polygon. When the plurality of holes 13b1 form a figure, it is preferable that the rotation axis 5 is at the center.

[0036] The fluid supply member 33 may be a nozzle or shower that sprays the fluid directly or as a mist. The fluid, such as air, tap water, cold water, warm water, hot water, or cooling water, that has flowed through the supply pipe 31, is sprayed from the fluid supply member 33 to the material inlet 14b of the material input section 14. The sprayed fluid is supplied from the material inlet 14b to the material supply section 3a and mixed with the material. The fluid may be supplied to the material inlet 14b in advance, or may be supplied to the material inlet 14b during operation. At least one of the multiple fluid supply members 33 may be in operation, but it is preferable to operate all of the multiple fluid supply members 33 in order to avoid uneven supply.

[0037] The mixing and melting apparatus 1 of this embodiment further includes a cooling section 22 that cools the mixing vessel 3 by circulating cooling water, and the cooling section 22 has a water passage 24 formed continuously in the peripheral wall of the mixing vessel 3, and communicates with the water passage 24 and the supply pipe 31, and uses cooling water as a fluid. Therefore, the mixing and melting apparatus 1 of this embodiment can appropriately adjust the temperature inside the mixing vessel 3.

[0038] In this way, the fluid supply member 33 supplies a fluid to the material inlet portion 14b, so that the amount of fluid in the mixing container 3 can be adjusted before, during, and after the fusion of the materials. For example, a fluid such as water can be added to the materials before melting, and the internal pressure can be increased in a later process. Also, the inside of the mixing container 3 after melting can be cooled. Furthermore, the appropriate amount of fluid to be added for each material to be fused can be automatically controlled and managed, and quantitative mass production can be achieved. Also, a fluid such as water can be added after the materials are charged, and the materials are charged in a dry state, so that charging errors are less likely to occur.

[0039] In addition, by spraying mist from the fluid supply member 33 before melting, the fluid can be uniformly sprayed onto the material before melting. Therefore, the fluid is uniformly applied to the entire fusion material, and heat can be uniformly transferred during fusion or cooling. In addition, after fusion, a product with uniform physical properties and high strength can be obtained. During cooling, the fused material can be rapidly cooled, and thermal deterioration of the material can be mitigated.

[0040] FIG. 6 shows a front view of the fluid supplying section 30 of the mixing and melting apparatus 1 of the second embodiment.

[0041] The fluid supply unit 30 of the second embodiment is connected to the material supply unit 3a of the mixing and melting apparatus 1. The fluid supply unit 30 has a supply pipe 31, a flow rate control unit 32 installed in the middle of the supply pipe 31, and a fluid supply member 33 installed at the tip of the supply pipe 31.

[0042] Supply pipe 31 is a pipe through which a fluid flows, such as air, tap water, cold water, warm water, hot water, or cooling water cooled by cooling tower 23 shown in Fig. 3. The amount of fluid flowing through supply pipe 31 is adjusted by flow rate control unit 32. Flow rate control unit 32 is installed midway through supply pipe 31, and may control the flow rate of the fluid passing through supply pipe 31 by, for example, adjusting the rotation angle of a valve.

[0043] The fluid supplying member 33 of the second embodiment is installed in a hole 3a1 formed in the material supplying section 3a. In the mixing and melting device 1, at least one hole 3a1 is formed in the material supplying section 3a, and a fluid supplying member 33 is installed therein. A plurality of holes 3a1 may be formed in the material supplying section 3a, and a plurality of fluid supplying members 33 may be installed therein.

[0044] In the second embodiment, the holes 3a1 are arranged vertically in pairs above and below the material supply unit 3a, and a fluid supply member 33 is installed in each of the holes 3a1. The number of holes 3a1 may be two or more. The holes 3a1 may be arranged horizontally or diagonally. Lines connecting the holes 3a1 without intersecting each other may form a square, rectangle, trapezoid, or regular polygon. When the holes 13b1 form a figure, it is preferable that the rotation axis 5 is at the center.

[0045] The fluid supplying member 33 may be a nozzle or shower that sprays the fluid directly or as a mist. The fluid, such as air, tap water, cold water, warm water, hot water, or cooling water, that has flowed through the supply pipe 31, is sprayed from the fluid supplying member 33 into the material supplying section 3a. The sprayed fluid is supplied to the material supplying section 3a and mixed with the material. The fluid may be supplied to the material supplying section 3a in advance, or may be supplied to the material supplying section 3a during operation. At least one of the multiple fluid supplying members 33 may be in operation, but it is preferable that all of the multiple fluid supplying members 33 are in operation to avoid uneven supply.

[0046] The mixing and melting apparatus 1 of this embodiment further includes a cooling section 22 that cools the mixing vessel 3 by circulating cooling water, and the cooling section 22 has a water passage 24 formed continuously in the peripheral wall of the mixing vessel 3, and communicates with the water passage 24 and the supply pipe 31, and uses cooling water as a fluid. Therefore, the mixing and melting apparatus 1 of this embodiment can appropriately adjust the temperature inside the mixing vessel 3.

[0047] In this way, the fluid supply member 33 supplies the fluid to the material supply section 3a, so that the amount of fluid in the mixing container 3 can be adjusted before, during, and after the fusion of the materials. For example, a fluid such as water can be added to the materials before melting, and the internal pressure can be increased in a later process. Also, the inside of the mixing container 3 after melting can be cooled. Furthermore, the appropriate amount of fluid to be added for each material to be fused can be automatically controlled and managed, and quantitative mass production can be achieved. Also, the fluid can be added after the materials are added, and the materials are added in a dry state, so that feeding defects are less likely to occur.

[0048] In addition, by spraying mist from the fluid supply member 33 before melting, the fluid can be uniformly sprayed onto the material before melting. Therefore, the fluid is uniformly applied to the entire fusion material, and heat can be uniformly transferred during fusion or cooling. In addition, after fusion, a product with uniform physical properties and high strength can be obtained. During cooling, the fused material can be rapidly cooled, and thermal deterioration of the material can be mitigated.

[0049] Fig. 7 shows a front view of the fluid supplying section 30 of the mixing and melting apparatus 1 of the third embodiment. Fig. 8 shows a side view of the fluid supplying section 30 of the mixing and melting apparatus 1 of the third embodiment.

[0050] The fluid supply unit 30 of the third embodiment is connected to the blade member 10 side of the mixing vessel 3 of the mixing and melting apparatus 1. The fluid supply unit 30 has a supply pipe 31, a flow rate control unit 32 installed in the middle of the supply pipe 31, and a fluid supply member 33 installed at the tip of the supply pipe 31.

[0051] Supply pipe 31 is a pipe through which a fluid flows, such as air, tap water, cold water, warm water, hot water, or cooling water cooled by cooling tower 23 shown in Fig. 3. The amount of fluid flowing through supply pipe 31 is adjusted by flow rate control unit 32. Flow rate control unit 32 is installed midway through supply pipe 31, and may control the flow rate of the fluid passing through supply pipe 31 by, for example, adjusting the rotation angle of a valve.

[0052] The fluid supplying member 33 of the third embodiment is installed in a hole 3b1 formed in the material mixing section 3b. In the mixing and melting device 1, at least one hole 3b1 is formed in the material mixing section 3b, and the fluid supplying member 33 is installed. A plurality of holes 3b1 may be formed in the material mixing section 3b, and a plurality of fluid supplying members 33 may be installed.

[0053] In the third embodiment, the holes 3b1 are arranged two by two on each side of the upper and lower parts of the material mixing section 3b, and the lines connecting them form a square, and a fluid supply member 33 is installed in each of the holes 3b1. The number of holes 3b1 may be two or more. The holes 3b1 may be arranged vertically, horizontally, or diagonally. Furthermore, the lines connecting the holes 3b1 without intersecting each other may form a square, rectangle, trapezoid, or regular polygon. When the holes 3b1 form a figure, it is preferable that the rotation axis 5 is at the center.

[0054] The fluid supplying member 33 may be a nozzle or shower that sprays the fluid directly or as a mist. The fluid, such as air, tap water, cold water, warm water, hot water, or cooling water, that has flowed through the supply pipe 31, is sprayed from the fluid supplying member 33 into the mixing container 3. The sprayed fluid is supplied to the mixing container 3 and mixed with the materials. The fluid may be supplied to the mixing container 3 in advance, or may be supplied to the mixing container 3 during operation. It is sufficient that at least one of the multiple fluid supplying members 33 is in operation, but it is preferable that all of the multiple fluid supplying members 33 are in operation to avoid uneven supply.

[0055] The mixing and melting apparatus 1 of this embodiment further includes a cooling section 22 that cools the mixing vessel 3 by circulating cooling water, and the cooling section 22 has a water passage 24 formed continuously in the peripheral wall of the mixing vessel 3, and communicates with the water passage 24 and the supply pipe 31, and uses cooling water as a fluid. Therefore, the mixing and melting apparatus 1 of this embodiment can appropriately adjust the temperature inside the mixing vessel 3.

[0056] In this way, the fluid supply member 33 supplies fluid to the material mixing section 3b, so that the amount of fluid in the mixing container 3 can be adjusted before, during, and after the materials are fused. For example, a fluid such as water can be added to the materials before melting, and the internal pressure can be increased in a later process. Also, the inside of the mixing container 3 after melting can be cooled. Furthermore, the appropriate amount of fluid to be added for each material to be fused can be automatically controlled and managed, and quantitative mass production can be achieved. Also, since the fluid can be added after the materials are added, and the materials are added in a dry state, there is less chance of improper addition.

[0057] In addition, by spraying mist from the fluid supply member 33 before melting, the fluid can be uniformly sprayed onto the material before melting. Therefore, the fluid is uniformly applied to the entire fusion material, and heat can be uniformly transferred during fusion or cooling. In addition, after fusion, a product with uniform physical properties and high strength can be obtained. During cooling, the fused material can be rapidly cooled, and thermal deterioration of the material can be mitigated.

[0058] In addition, the fluid supplying member 33 of the first to third embodiments may adjust either the temperature or the flow rate of the fluid to be sprayed based on either the outside air temperature or the type of material in a temperature adjusting unit and a flow rate control unit 32 (not shown). In addition, the fluid supplying members 33 of the first to third embodiments may be used in various combinations. For example, the mixing and melting device 1 may be installed by combining the fluid supplying members 33 of the first and second embodiments, the fluid supplying members 33 of the second and third embodiments, the fluid supplying members 33 of the first and third embodiments, and the fluid supplying members 33 of the first to third embodiments.

[0059] As described above, the mixing and melting apparatus 1 of this embodiment comprises a motor 8 that generates a driving force, a rotating shaft 5 that is rotated by the motor 8, a spiral supply screw 12 formed on the outer periphery of one side in the axial direction of the rotating shaft 5, a plurality of blade members 10 formed on the outer periphery of the other side in the axial direction of the rotating shaft 5, a material input section 14 into which material is input, a mixing container 3 that is connected below the material input section 14 and through which the rotating shaft 5 passes, and which crushes, mixes and melts the material input into the material input section 14, and a fluid supply section 30 that supplies fluid to the material input section 14 or the mixing container 3.

[0060] Therefore, the mixing and melting device 1 of this embodiment can adjust the amount of fluid in the mixing container 3 at any time before, during, or after the materials are fused. For example, the appropriate amount of fluid to be added for each material to be fused can be automatically controlled and managed, enabling quantitative mass production. In addition, the fluid can be added after the materials are charged, and the materials are charged in a dry state, making it less likely that charging errors will occur.

[0061] In the mixing and melting apparatus 1 of the present embodiment, the fluid supplying section 30 includes a supply pipe 31 and a fluid supplying member 33 that is installed at the tip of the supply pipe 31 and supplies the fluid. Therefore, the mixing and melting apparatus 1 of the present embodiment can appropriately adjust the amount of fluid in the mixing container 3.

[0062] Moreover, in the mixing and melting apparatus 1 of this embodiment, the fluid supplying section 30 has a plurality of fluid supplying members 33. Therefore, the mixing and melting apparatus 1 of this embodiment can adjust the water content in the mixing container 3 more appropriately.

[0063] In addition, in the mixing and melting device 1 of this embodiment, the fluid supplying member 33 is a nozzle or shower that sprays the fluid as a mist. Therefore, the mixing and melting device 1 of this embodiment can uniformly spray the fluid onto the material in the mixing container 3. Therefore, the fluid is uniformly applied to the entire fusion material, and heat can be uniformly transferred during fusion or cooling. In addition, after fusion, a product with uniform physical properties and high strength can be obtained. During cooling, the fused material can be rapidly cooled, and thermal deterioration of the material can be mitigated.

[0064] In the mixing and melting apparatus 1 of the present embodiment, the fluid supplying section 30 is further provided with a flow rate control section 32 that is installed in the middle of the supply pipe 31 and adjusts the flow rate of the fluid. Therefore, the mixing and melting apparatus 1 of the present embodiment can more appropriately adjust the amount of fluid in the mixing container 3.
