Description

[Technical Field]

[0001] The present invention relates to an agitation and rotation device and an agitation device suitable for agitating high-melting-point adhesive materials. [Background technology]

[0002] Conventionally, there is an agitator such as that described in Patent Document 1. This agitator is equipped with a scraping blade, and can scrape and agitate the material to be stirred in the stirring vessel while heating it by the rotation and revolution of this scraping blade.

[0003] When such a mixer is used to mix a molten high-melting-point adhesive material such as candy with particulate solids, the high-melting-point adhesive material adheres to the scraping blade and the shaft that supports it in the rotating part, and the adhesion grows and increases over time.

[0004] In particular, the blade pipes that support the scraping blades on the rotating part are made of metal to maintain their strength because they are subject to resistance from the material being stirred during the scraping and stirring process. For this reason, if a molten high-melting-point adhesive material adheres to the blade pipes, it is easy for it to grow as an adhesion.

[0005] Furthermore, the heating and mixing history of this deposit is uneven and insufficient compared to the product, and if the peeled deposit gets mixed into the product, there is a problem in that the quality of the product becomes uneven.

[0006] Furthermore, there are problems such as an increase in the time required for cleaning the scraping blades and the like after the end of production to remove deposits, and a decrease in product yield due to the increase in deposits.

[0007] For this reason, it is essential to suppress the growth of deposits in the scraping and stirring process that involves heating the high-melting-point adhesive material.

[0008] Furthermore, when the high-melting-point adhesive material is transferred to another mixing device or the like for subsequent processing, the growth of such deposits can also occur in transfer chutes or the like where heat from gas heating or the like is difficult to reach, so it is important to similarly suppress the growth of deposits.

[0041] [Mixing device] FIG. 1 is a schematic cross-sectional view of a stirring device according to a first embodiment, with some parts omitted, as viewed from the front side.

[0042] 1 shows the main components of a vertical heating and stirring device, which stirs and mixes a molten high-melting-point adhesive material, such as candy, with a particulate solid.

[0043] The stirring device 1 is provided with a stirring and rotating device 5 for a stirring vessel 3 .

[0044] The stirring vessel 3 is made of iron, stainless steel, copper, or the like and is formed in a pan shape with a dish-shaped bottom at the bottom. The stirring vessel 3 is supported on a base frame (not shown). A gas heating device (not shown) is provided on the base frame and is positioned below the stirring vessel 3. The bottom of the stirring vessel 3 can be heated by the gas heating device under the control of a control box.

[0045] The agitation rotation device 5 includes an agitation main drive shaft 9 , a revolution box 11 , and an agitation drive shaft 13 .

[0046] The main agitation drive shaft 9 is provided on the top of the agitation vessel 3 and is supported at the tip of the agitation head 15. The main agitation drive shaft 9 is rotated and driven by a geared motor 17, which is the drive unit inside the agitation head 15, and is configured to rotate on its own axis. The geared motor 17 is driven and controlled by a control box not shown.

[0047] The revolution box 11 has a box shape that is approximately oval when viewed from above, and its base end is supported by the main agitation drive shaft 9, with its tip end revolving around the main agitation drive shaft 9 as the main agitation drive shaft 9 rotates.

[0048] The agitation drive shaft 13 is rotatably supported by a shaft support cylinder 19 at the tip end of the revolution box 11, and is configured to be interlocked with the agitation main drive shaft 9 by gear coupling.

[0049] A plate-shaped agitation swirl part 21, which is a rotating part, is attached to the agitation drive shaft 13, and scraping blades 27, 29 made of fluororesin, which are scrapers, are supported on the agitation swirl part 21 via blade pipes 23, 25, which are metal support rods. A scraping blade 33 made of fluororesin, which is a scraper, is attached to the shaft support cylinder 19 via a bent blade pipe 31, which is a metal support rod.

[0050] The scraping blades 27 , 29 , and 33 are used to scrape and stir the inside of the stirring vessel 3 .

[0051] That is, as the revolution box 11 revolves, the scraping blade 33 revolves via the blade pipe 31 due to the shaft support cylinder 19, which revolves around the shaft 9, and scrapes off solid matter adhering to the side wall of the agitator vessel 3 due to the adhesive material toward the bottom. At the same time, the rotation and revolution of the agitator drive shaft 13 causes the scraping blades 27, 29 to revolve at the bottom via the blade pipes 23, 25, performing a scraping operation. In this way, the solid matter and adhesive material can be effectively agitated and mixed throughout the entire agitator vessel 3.

[0052] The mixing head 15 is rotatably supported on a head support bracket on the base frame side. A hydraulic cylinder device (not shown) is supported between the mixing head 15 and the base frame side. The hydraulic cylinder device is driven and controlled by a control box (not shown). Driving the hydraulic cylinder device rotates the mixing head 15 to retract upward, allowing the mixing vessel 3 to tilt.

[0053] The structure and relationship between the vane pipe 23 and the scraping blade 27 and the vane pipe 25 and the scraping blade 29 are almost the same, and the vane pipe 23 and the scraping blade 27 will be explained using Figures 2 to 5, and an explanation of the vane pipe 25 and the scraping blade 29 will be omitted.

[0054] Fig. 2 is a schematic front view of the scraping blade attached to the support rod according to the first embodiment. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2 according to the first embodiment. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3 according to the first embodiment. Fig. 5 is a rear view of the scraping blade attached to the blade mounting plate according to the first embodiment.

[0055] As shown in FIGS. 2 and 3, a scraping blade 27 is connected to the tip of the blade pipe 23.

[0056] The vane pipe 23 is formed into a cylindrical shape from stainless steel or the like, and has a fluororesin cover member 35 attached to its upper part and a stainless steel knuckle portion 37 attached to its lower part as a vane support portion. The outer diameter of the knuckle portion 37 is set to be the same as the outer diameter of the vane pipe 23. A stainless steel stopper ring 38 is fixed to the middle portion of the outer surface of the vane pipe 23 in the axial direction.

[0057] The lower part of a mounting shaft 39 made of stainless steel or the like is inserted into the impeller pipe 23, and this mounting shaft 39 penetrates the cover member 35 and protrudes outside the impeller pipe 23. The upper end of the mounting shaft 39 is fitted into a cylindrical body 41 fixed to the stirring and swirling part 21 as shown in Figure 1, and a pin 43 penetrates the cylindrical body 41 and the mounting shaft 39 to prevent the mounting shaft 39 from rotating relative to the cylindrical body 41.

[0058] The knuckle portion 37 is fixed to the tip of the blade pipe 23. The knuckle portion 37 is bifurcated to support the scraping blade 27, and has a through hole and a screw hole for bolt connection distributed between the two branches.

[0059] 3 and 4, a guide pipe 44 for guiding expansion and contraction is installed inside the vane pipe 23. The guide pipe 44 is made of stainless steel or the like, and has a guide hole 44a.

[0060] The lower end of the mounting shaft 39 is fitted into the guide hole 44a and is movable along the guide hole 44a. An engaging guide piece 45 is fixed to the lower end of the mounting shaft 39. The guide piece 45 is fitted into the guide hole 44a and is guided to move relatively along the guide hole 44a while its rotation around the axis is restricted.

[0061] A spring bearing 47 is fixed to the mounting shaft 39 on the side of the cover member 35. A coil spring 49 is disposed between the spring bearing 47 and the guide pipe 44.

[0062] Therefore, when the blade pipe 23 receives an upward thrust from the scraping blade 27 side via the knuckle portion 37, the blade pipe 23 moves upward while the guide hole 44a is guided by the guide piece 45. This movement causes the blade pipe 23 to contract upward relative to the mounting shaft 39. At this time, the coil spring 49 pressed against the guide pipe 44 is received by the spring receiver 47, and the coil spring 49 is compressed.

[0063] When the upward thrust force on the vane pipe 23 is removed, the resilient force of the coil spring 49 is input to the vane pipe 23 via the guide pipe 44 , causing the vane pipe 23 to move and expand relative to the mounting shaft 39 .

[0064] 2, 3, and 5 are made of a material, such as fluororesin, that reduces the coefficient of friction with the stirring vessel 3 and has a lower thermal conductivity than metals such as stainless steel. The scraping blade 27 is formed in a plate shape and is approximately rectangular when viewed from the front. The blade tip 27a of the stirring blade 27 is curved to match the curved bottom of the stirring vessel 3.

[0065] The back surface of the scraping blade 27 is supported by a blade mounting plate 51. The blade mounting plate 51 is smaller than the scraping blade 27 and is placed on the center of the upper back surface of the scraping blade 27, and the scraping blade 27 is fastened and fixed by bolts 53 at two locations.

[0066] The blade mounting plate 51 has a blade side mounting portion 55 that is coupled to the knuckle portion 37. The blade side mounting portion 55 protrudes upward from the center of the upper edge of the blade mounting plate 51. The blade side mounting portion 55 is inserted into the fork of the knuckle portion 37. A bolt 57 passes through the blade side mounting portion 55 in a loose fit state, and the bolt 57 is screwed into the knuckle portion 37. The bolt 57 has an enlarged fitting portion 57a ​​outside the knuckle portion 37, and a bolt head is provided on the end surface of the enlarged fitting portion 57a.

[0067] The blade pipe 23 is provided with a support rod covering portion 59 that forms an outer shell. Covering part 59 is made of a material with a relatively low thermal conductivity compared to the vane pipe 23. Covering part In this embodiment, the material of 59 is a fluororesin.

[0068] the support rod Covering part Reference numeral 59 denotes a cover tube made of fluororesin that is formed in a substantially cylindrical shape and that encloses the blade pipe 23. Covering part The inner diameter of 59 is approximately equal to the outer diameter of the vane pipe 23. Covering part The blade pipe 23 is enclosed by the support rod 59 from the lower end of the blade pipe 23 to about halfway in the axial direction. Covering part The vane pipe 23 can also be entirely enclosed by the vane pipe 59.

[0069] the support rod Covering part The upper end of 59 abuts against the stopper ring 38 .

[0070] the support rod Covering part A pair of cover tongues 59c and 59d are integrally formed at the lower end of the support rod 59. Covering part The thickness of the inner side of the cylinder diameter of 59 is increased, and the blade side mounting part 55 One of the cover tongues 59d is chamfered 59e in accordance with the rake angle of the scraping blade 27. Covering part The lower end of 59 is formed with a bottom, and a slit is formed in the bottom portion to form the blade side mounting portion. 55 It is also possible to configure the wire so that it passes through the wire.

[0071] the support rod Covering part A radial through-hole 59f is formed adjacent to the cover tongue portion 59c in the cover 59. The enlarged fitting portion 57a ​​of the bolt 57 is fitted into the through-hole 59f.

[0072] the support rod Covering part 59 is positioned in the axial direction by the stopper ring 38 and the enlarged fitting portion 57a.

[0073] Thus, the support rod Covering part 59 forms the outer shell of the blade pipe 23. In this state, the support rod Covering part 59 is configured to cover the blade side mounting portion 55 including the knuckle portion 37.

[0074] However, the support rod Covering part The range over which the blade pipe 23 is covered by the blade 59 can be freely set.

[0075] The blade mounting plate 51 is provided with a mounting plate for covering it. Covering part 63. The mounting plate Covering part The blade mounting plate 63 is made of a material having a relatively low thermal conductivity compared to the blade mounting plate 51. Covering partIn this embodiment, the material of the mounting plate 63 is fluororesin. Covering part Reference numeral 63 denotes a cover plate made of fluororesin that covers the back surface of the blade mounting plate 51. Covering part 3 and 5, the blade mounting plate 51 is almost entirely covered by the rear surface of the blade mounting plate 51. Covering part The edges of 63 are chamfered. Covering part 63 is fastened and fixed to the blade mounting plate 51 with two screws 65.

[0076] In this embodiment, the blade pipe 25 is provided with the support rod shown in FIG. Covering part 59, and the blade mounting plate of the scraping blade 29 is provided with the mounting plate shown in FIGS. Covering part It has the same configuration as the 63.

[0077] The scraping blade 33 on the outer periphery is attached to the blade pipe 31 by a blade mounting plate made of stainless steel or the like, in the same manner as the scraping blades 27 and 29. Therefore, the scraping blade 33 is also attached to the blade mounting plate in the same structure as the mounting plate shown in Figs. Covering part However, the scraping blade 33 has a different shape from the scraping blades 27 and 29, and the blade mounting plate also has a different shape. Covering part It goes without saying that the blade mounting plate is formed in a shape that covers the blade mounting plate.

[0078] The blade pipe 31 is disposed at a relatively high position in the agitation vessel 3 and does not come into contact with the material to be treated, such as adhesive material. Covering part However, in the case where the material to be treated adheres to the blade pipe 31, the support rod Covering part may also be provided.

[0079] [Agitation drive] The stirring vessel 3 of the stirrer 1 is heated and controlled by a gas heating device when the stirring and rotating device 5 is in operation. In the stirrer 1, a rotational driving force is transmitted to the main stirring drive shaft 9 via the stirring head 15. When the main stirring drive shaft 9 rotates, the revolution box 11 revolves integrally with the main stirring drive shaft 9 around its axis. This rotation causes the stirring drive shaft 13 to revolve around the center of the stirring vessel 3, which is the axis of the main stirring drive shaft 9.

[0080] At the same time, rotational driving force is transmitted from the main agitation drive shaft 9 to the agitation drive shaft 13 via the meshing of gears inside the revolution box 11. This rotational transmission drives the agitation drive shaft 13 to rotate about its axis.

[0081] That is, the agitation drive shaft 13 is driven to rotate and revolve around the axis of the agitation main drive shaft 9, and the scraping blades 27, 29 move while scraping the bottom of the agitation vessel 3. In addition, the outer peripheral scraping blade 33 revolves together with the shaft support cylinder 19, scraping the side wall of the agitation vessel 3 while moving.

[0082] The bottom of the stirring vessel 3 is a heat transfer surface that is directly heated, and heat transfer is promoted by scraping with the scraping blades 27, 29, and 33. In particular, the adhesive material on the bottom is renewed, which is highly effective in preventing burning.

[0083] [Manufacturing of processed materials] First, raw materials of granular or lumpy solid material and adhesive material are charged into the stirring vessel 3 .

[0084] When the stirring and rotating device 5 is driven and controlled, the blade pipes 23, 25, and 31 rotate due to the rotation and revolution of the stirring drive shaft 13, and the scraping blades 27, 29, and 33 perform scraping and stirring operations. At the same time, the gas heating device is operated under the control of the control box, and the stirring vessel 3 is heated and controlled. The raw materials in the stirring vessel 3 are stirred while being heated.

[0085] When such a mixing device 1 is used to mix a molten high-melting-point adhesive material such as candy with a particulate solid, the high-melting-point adhesive material tends to adhere to the scraping blades 27, 29, 33, etc. and the blade pipes 23, 25, etc. that support them.

[0086] At this time, the blade pipe 23, the support rod covering portion 59 of the scraping blade 27, and the mounting plate Covering part Even if a high melting point adhesive material is attached to 63, the low thermal conductivity prevents the high melting point adhesive material from losing heat. Covering part 59 and mounting plate Covering part The low coefficient of friction of 63 prevents the high melting point adhesive material from growing as an adhesion.

[0087] This action is performed by the blade pipe 25 and the support rod of the scraping blade 29. Covering part and mounting plate Covering part , the mounting plate of the scraping blade 33 Covering part The same is true for

[0088] Therefore, the grown deposits are prevented from peeling off and contaminating the product, thereby improving the quality of the product.

[0089] Furthermore, the time required for cleaning the blade pipes 23, 25, scraping blades 27, 29, etc. after production is completed can be reduced, and a decrease in product yield can be suppressed. [Example]

Fig. 7(A) is a schematic plan view of the agitation treatment device equipped with first and second agitation treatment units when discharging water, and (B) is a schematic side view of the agitation treatment device equipped with first and second agitation treatment units when discharging water.

[0091] The agitation processing device 101 in Figures 6 and 7 is used to obtain a processed product in which granular or lumpy solid material is coated with an adhesive material and then broken down into granules or lumps. The granular or lumpy solid material may be anything that can be coated with an adhesive material, such as nuts, popcorn, or natto. The adhesive material may be anything that can coat the solid material by agitation, such as caramel.

[0092] 6 and 7, the stirring device 101 includes first and second stirring processing sections 103 and 105. The first stirring device 103 is configured as a vertical heating stirring device, and the second stirring processing section 105 is configured as a horizontal stirring device.

[0093] The first and second stirring processing units 103 and 105 are arranged adjacent to each other. The first stirring processing unit 103 is configured such that a first stirring unit 109 rotates laterally (horizontally) relative to a first stirring vessel 107. The second stirring processing unit 105 is configured such that a second stirring unit rotates up and down (vertically) relative to a second stirring vessel 111.

[0094] An intermediate processed product is produced by subjecting the granular or lumped solid material and adhesive material in the first agitation vessel 107 to a first stage of agitation treatment in the first agitation unit 109 while heating. The intermediate processed product is transferred from the first agitation vessel 107 to the second agitation vessel 111, where it is subjected to a second stage of agitation treatment in the vertical direction by the second agitation unit while cooling. The second stage of agitation treatment produces a processed product in which the granular or lumped solid material is coated with the adhesive material and is substantially broken down into particles or lumps.

[0095] The first stirring section 109 has the same configuration as the stirring and rotating device 5 of the first embodiment, and is provided with a configuration corresponding to the support rod covering section 59 (cover tube) and the mounting plate covering section 63.

[0096] The first agitator vessel 107 can be tilted to either a transfer mode or a cleaning mode toward the second agitator vessel 111. In the transfer mode of the first agitator vessel 107, the inclination of the first agitator vessel 107 is used to transfer the intermediate processed product from the previous agitation process to the second agitator vessel 111, and in the cleaning mode of the first agitator vessel 107, the cleaning water inside the first agitator vessel 107 can be discharged.

[0097] The mixing head 137 is rotatably supported on a head support bracket 155 on the base frame 117 side, as shown in Figure 6(B). A hydraulic cylinder device 157 is supported between the mixing head 137 and the base frame 117 side. The hydraulic cylinder device 157 is driven and controlled by the control box 126. By driving the hydraulic cylinder device 157, the mixing head 137 is rotated and retracted upward, allowing the first mixing vessel 107 to tilt.

[0098] [Vertical heating and stirring device] The first stirring processing unit 103 produces an intermediate processed product by a first stirring process that involves heating granular or lumpy solids, such as nuts, to roast them and sugar to caramelize them.

[0099] The first stirring vessel 107 of the first stirring processing section 103 is made of iron, stainless steel, copper, or the like and is formed in a pan shape with a dish-shaped bottom at the bottom. A spout 179 is provided on one side of the opening of the first stirring vessel 107.

[0100] The spout 179 is formed to protrude outward from the first stirring container 107 toward the second stirring processing section 105 and is formed to be slightly tapered. The spout 179 is formed in a gutter shape by a bottom plate and left and right guide plates that rise along the bottom plate.

[0101] The spout 179 is made of a metal such as stainless steel, similar to the first stirring vessel 107, and is integrally joined to the first stirring vessel 107. The entire front and back of the spout 179 are lined with fluororesin, for example. The fluororesin lining is made of a material with a relatively low thermal conductivity compared to the stainless steel spout 179. Covering part The spout Covering part The structure may be such that the contact surfaces are provided only on the upper surface of the bottom plate and the inner surfaces of the left and right guide plates, which are areas that come into contact with the intermediate processed material during transport.

[0102] The first stirring vessel 107 is supported by a base frame 117 so as to be able to rotate and tilt. The base frame 117 is constructed in a substantially rectangular shape and has legs at the four corners. The base frame 117 is provided with left and right rotation support parts 119 on the side of the second stirring processing part 111. The rotation support parts 119 are formed to include ball bearings and the like. A rotation shaft 121 is supported by the rotation support part 119. The rotation shaft 121 is disposed on and supported by the base frame 117.

[0103] A gas heating device 125 is provided on the base frame 117 and is arranged below the first stirring vessel 107. The bottom of the first stirring vessel 107 can be heated by the gas heating device 125 under the control of a control box 126.

[0104] A hydraulic cylinder device 130 is supported between the base frame 117 and the first agitating vessel 107. The hydraulic cylinder device 130 is controlled by a control box 126. By driving this hydraulic cylinder device 130, the first agitating vessel 107 is tilted toward the second agitating vessel 111 as shown by the chain line in FIG. 6(B).

[0105] [Horizontal mixing device] The second agitation processing unit 105 is composed of a horizontal agitation device, and the intermediate processed product is transferred from the first agitation processing unit 103 to the second agitation processing unit 105, and is cooled and subjected to a subsequent agitation process in the vertical direction by the second agitation processing unit 105. By this subsequent agitation process, a processed product is obtained in which the nuts are coated with caramel and the nuts are loosened almost individually.

[0106] The second agitator vessel 111 of the second agitation processing section 105 receives the intermediately processed material from the first agitator vessel 107 and is made of iron, stainless steel, copper, or the like. The second agitator vessel 111 has a hopper section 161 integrally attached to the top of a horizontally placed cylindrical section 159. The hopper section 161 forms an upper opening of the second agitator vessel 111. The second agitator vessel 111 is supported by a base frame 162 so as to be tiltable in both directions around an axis. This tilting movement is performed by control of a hydraulic cylinder by a control box 169, or the like.

[0107] The rotation shaft of the second agitator is disposed laterally and rotatably supported at the axial center of the cylindrical portion 159. The rotation shaft is driven to rotate by a drive motor on the control box 169 side. Agitation arms are attached to the rotation shaft at predetermined intervals, and a scraping blade is attached to the tip of each agitation arm.

[0108] The scraping blade located in the axial middle part inside the second stirring vessel 111 is arranged to rotate and scrape the cylindrical part 159 of the second stirring vessel 111. The tip of this scraping blade is arranged along the axial direction inside the second stirring vessel 111, and the tip edge of the blade is linear.

[0109] The scraping blades on both sides in the axial direction inside the second stirring vessel 111 are arranged to rotate around a rotation axis to scrape the curved surfaces on both sides in the axial direction of the second stirring vessel 111 .

[0110] In other words, these scraping blades are shaped and positioned to stir the intermediate processed material transferred from the first stirring processing unit 103 while cooling it, solidify sticky materials such as caramel coated on solid matter such as nut kernels, and stir the material so as to break up each solid matter.

[0111] The cylindrical portion 159 of the second stirring vessel 111 is provided with a cooling fluid jacket 171 on the outer periphery of the lower portion. The fluid jacket 171 is connected to a water supply unit by a water supply pipe, and the supply of cooling water from the water supply unit to the fluid jacket 171 can be controlled by the control of the control box 169. The temperature of the cooling water can be changed by the control of the control box 169.

[0112] [Shoot] The agitation processing device 101 of the second embodiment is provided with a chute 175 between the first and second agitation processing sections 103 and 105 .

[0113] The chute 175 is disposed between the first stirring vessel 107 and the second stirring vessel 111 in a linked manner. The chute 175 is made of a metal such as stainless steel and is lined with a fluororesin. The fluororesin lining is a chute made of a material with a relatively low thermal conductivity compared to the metal chute 175. Covering part Compose a Shoot Covering part are provided on the entire chute 175, but may be configured to be provided only in the area that comes into contact with the intermediate processed material during transport.

[0114] The chute 175 has a flat chute bottom and chute side walls on both sides. The chute 175 is rotatably supported on a chute frame 178 by a rotation shaft 176. The chute frame 178 faces the first rotation support portion 119 of the base frame 117 of the first mixing processing section 103.

[0115] The chute frame 178 is independent of the base frames 117 and 162 of the first and second mixing processing sections 103 and 105. The chute frame 178 can also be moved relative to the first and second mixing processing sections 103 and 105.

[0116] As shown in Figures 6(A) and 6(B), when the intermediate processed material is transferred from the mixing treatment device 101, the chute 175 is inclined downward from the first mixing vessel 107 side to the second mixing vessel 111 side. In this state, the spout 179 of the tilted first mixing vessel 107 is positioned above one end of the bottom of the chute 175. The chute side walls are located on both sides of the spout 179 of the first mixing vessel 107, which is positioned above this end of the bottom of the chute. The bottom of the chute 175, which is inclined downward toward the second mixing vessel 111, has its tip protruding beyond the chute side walls and is inserted into the hopper portion 161 of the second mixing vessel 111. The chute side walls are located above the hopper portion 161.

[0117] As shown in Figures 7(A) and (B), when draining water from the agitation treatment device 101, the chute 175 is rotated about the rotation shaft 176, and is set to tilt downward toward the first agitation vessel 107. In this state, the spout 179 of the tilted first agitation vessel 107 faces the middle of the bottom of the chute 175. Chute side walls are located on both sides of the spout 179 of the first agitation vessel 107, which faces the middle of the bottom of the chute. A detachable cover 180 is attached to the upper end of the slope of the chute 175. The detachable cover 180 is used to prevent wastewater from splashing and is attached as appropriate when draining water.

[0118] [Manufacturing of processed materials] First, raw materials of granular or lumpy solid material and adhesive material are charged into the first stirring vessel 107 .

[0119] When the first agitator 109 is driven and controlled, the scraping blade rotates and revolves. At the same time, the gas heater 25 is operated under the control of the control box 126, and the first agitator vessel 107 is heated and controlled. In this state, the first agitator 109 is driven and controlled, and the raw material in the first agitator vessel 107 is agitated while being heated, and an intermediate processed product is produced.

[0120] At this time, the support rod covering portion and the mounting plate in the first stirring portion 109 Covering partAs a result, the high melting point adhesive material on the blade pipes and the like is prevented from growing as an adhesion, as in Example 1, and the same effects can be achieved.

[0121] Next, the heating control of the first stirring vessel 107 and the drive control of the first stirring unit 109 are stopped, and the stirring head 137 is rotated to move the first stirring unit 109 to one side above the first stirring vessel 107 .

[0122] Next, the hydraulic cylinder device 130 is driven to tilt the first stirring vessel 107 toward the second stirring vessel 111 as shown by the chain line in FIG. 6(B).

[0123] In the state shown in Figures 6(A) and (B), the tilting action of the first agitating vessel 107 causes the high-melting-point, fluid intermediate processed material in the first agitating vessel 107 to move from the spout 179 along the chute 175, be smoothly received by the hopper section 161, and be transferred into the second agitating vessel 111.

[0124] At this time, heating in the gas heating device 25 of the first stirring vessel 107 is performed from the bottom side, and there is a risk that the temperature of the spout 179 and the chute 175 will not rise sufficiently. For this reason, if the spout 179 and the chute 175 remain made of metal such as stainless steel, the intermediate processed product, which is a mixture of a molten high-melting-point adhesive material and a particulate solid in a stirred state, such as candy, will tend to cool and stick together as it moves.

[0125] However, spout 179 is made of fluororesin. Covering part The Chute 175 is lined with fluorine resin. Covering part Since it is lined with , the thermal conductivity of the surface is lower than that of metals such as stainless steel.

[0126] Therefore, even if the high melting point adhesive material adheres to the spout 179 or the chute 175, the low thermal conductivity prevents the high melting point adhesive material from losing heat. Covering part and shoot Covering partThe low coefficient of friction of the high melting point adhesive material prevents the adhered material from growing as an adhering substance.

[0127] Therefore, the grown deposits are prevented from peeling off and contaminating the product, thereby improving the quality of the product.

[0128] Furthermore, the time required for cleaning the spout 179 and chute 175 after production to remove deposits can be reduced, and a decrease in product yield can also be suppressed.

[0129] When the intermediate processing material is transferred into the second agitator vessel 111 as described above, the tilting operation of the first agitator vessel 107 is reversed, and cooling water is supplied from the water supply unit through the water supply piping to the fluid jacket 171. In this state, the second agitator is driven, and in the second agitator vessel 111, the intermediate processing material is agitated while being cooled as a post-stage agitation treatment.

[0130] During the stirring process in this second stirring vessel 111, the intermediate processed material is stirred and rotated in the vertical direction by the stirring rotation of the scraping blade, and the adhesive material coated on the solid material is cooled and solidified, thereby obtaining a processed material that is broken down into particles or lumps.

[0131] At this time, since the stirring rotation in the second stirring vessel 111 is in the direction of gravity rather than horizontally, the solids scraped up by the scraping blades fall within the second stirring vessel 111, which promotes the separation of the solids from each other as the surface coating gradually solidifies.

[0132] When carrying out continuous batch production, similar operations are carried out successively.

[0133] After production is completed, both the first and second mixing processing units 103 and 105 are cleaned. In particular, the first mixing processing unit 103 needs to be cleaned by removing any adhesive material or solid matter adhering to the inside of the first mixing vessel 107 or the first mixing unit 109.

[0134] During this cleaning, since the adhesive material is not solidified, it can be easily dissolved and removed in a short time using hot water.

[0135] The washing water remaining in the first agitating vessel 107 after the washing can be drained smoothly by tilting the first agitating vessel 107 toward the spout 179 as shown by the chain line in FIG. 7(B).

[0136] When draining, the chute 175 is rotated on the rotation shaft 176 and is set to tilt downward toward the first agitation vessel 107. In this state, the spout 179 of the tilted first agitation vessel 107 faces the center of the bottom of the chute 175.

[0137] 7(A) and (B), the cleaning water discharged from the first agitator vessel 7 strikes the chute 75 from the spout 79 and is guided downward by the chute 75 to complete the discharge. Even if a small amount of adhesive material adheres to the chute 75 due to the transport of the intermediate processed material, the contact of the drained water promotes cleaning.
