<One Embodiment>
An embodiment of the present invention will be described with reference to FIGS.
1. FIG. 1 is a side view of the electric continuous baking machine 10, and FIG. 2 is a plan view of the electric continuous baking machine 10. The electric continuous baking machine 10 continuously uses a confectionery material (a mixture of powdered or liquid starch mixed with shrimp or squid pieces) in a baking chamber 30 in the main casing 20 using a lower conveyor 40. Then, it is sandwiched and baked by two upper and lower heating plates 55 and 75.

  Hereinafter, a specific configuration of the electric continuous baking machine 10 will be described. 1 and 2 (the longitudinal direction of the main body casing 20 and the feeding direction of the conveyors 40 and 60) are defined as the X direction throughout this specification, and the vertical direction of FIG. 2 (the depth direction of the main body casing 20). The direction perpendicular to the X direction) is defined as the Y direction.

  The electric continuous baking machine 10 presses the upper heating plate 75 of the upper conveyor 60 downward so as to overlap the main body casing 20, the lower conveyor 40, the upper conveyor 60, and the lower heating plate 55 of the lower conveyor 40. The pressing device 90 for heating and the heating device 100 for heating the upper and lower heating plates 55 and 75 are mainly configured.

  The main body casing 20 has a long shape in the X direction, and includes a frame 23 in which L-shaped steel materials (angles) are assembled into a frame shape, and a closing plate 25 that closes a window 24 of the frame 23.

  Steps are provided on the front and rear of the main casing 20, and raw materials arranged on the lower conveyor 40 described below are put into the firing chamber 30 in the main casing 20 on the front wall 20 </ b> A of the front step portion. Therefore, a raw material inlet (not shown) is provided. In addition, an outlet (not shown) is opened in the rear wall 20B of the rear stepped portion, and the baked baked confectionery (shrimp rice cracker or squid rice cracker) is discharged. Further, a dispenser 29 is provided at the rear part of the main casing 20 so that the baked confectionery that has passed through the outlet and out of the main casing 20 is discharged from the lower conveyor 40.

The lower conveyor 40 is attached to the lower side of the main casing 20. The lower conveyor 40 is a so-called chain drive type, and a drive shaft 41 is attached to the rear end portion of the main body casing 20, and a driven shaft 43 is attached to the front end portion of the main body casing 20 via a support member 87. A sprocket 42 is attached to both sides of the drive shaft 41, and a disc wheel 44 is attached to both sides of the driven shaft 43, and an endless chain 45 (“first” of the present invention is used to bridge them) . Equivalent to “Chain”) . The conveyor belt (conveyor belt) 50 of the lower conveyor 40 has a configuration in which a plurality of lower heating plates (cast iron plates) 55 are connected in a band shape, and both end portions of each lower heating plate 55 are connected. Are connected to the corresponding links 46 of the chain 45 (see FIGS. 3 and 5).

From the above, when the drive shaft 41 is rotated by the power unit 80, the conveyor belt 50 in which the lower heating plate 55 is connected in a belt shape by chain driving is circulated and driven in the X direction in the main body casing 20. The power device 80 includes a motor 81 and a transmission mechanism 83 that transmits the power of the motor 81 to the drive shaft 41. The support member 87 supports the driven shaft 43 so as to move back and forth while applying a certain elastic force to the driven shaft 43. Also, without providing the sprocket to each driven shaft 43, reason for providing a disc wheel 44 is for the purpose of allowing the thermal elongation of the lower heating plate 55, when this sprocket, the chain by engagement failure of the teeth This is because there is a risk of detachment. The power unit 80 and the lower conveyor (excluding the conveyor belt 50) 40 correspond to the “first drive unit” of the present invention.

  As shown in FIG. 3, a pair of first rails 57 extending horizontally in the X direction are attached to both sides in the Y direction, and the roller 47 of the chain 45 rolls on the upper surface thereof. It has become. By doing in this way, it becomes possible to keep the posture of the lower heating plate 55 forwardly fed horizontally.

The upper conveyor 60 is attached to the upper side of the main casing 20 and faces the lower conveyor 40 vertically. The upper conveyor 60 is a chain drive type like the lower conveyor 40, and a drive shaft 61 is attached to the rear end portion of the main body casing 20, and a driven shaft 63 is attached to the front end portion of the main body casing 20 via a support member 87. Yes. A sprocket 62 is attached to both sides of the drive shaft 61, and a disc wheel 64 is attached to both sides of the driven shaft 63. An endless chain (the “second chain” of the present invention is used to bridge them). Is equivalent to 65 ) . And the conveyor belt (conveyor belt) 70 of the upper conveyor 60 has a configuration in which a plurality of upper heating plates (cast iron plates) 75 are connected in a band shape, and both end portions of each upper heating plate 75 are connected to it. They are connected to the links 66 of the corresponding chains 65 (see FIGS. 3 and 6).

  A transmission mechanism 85 is provided between the drive shaft 61 and the motor 81 of the power device 80, and the power of the motor 81 is transmitted to the drive shaft 61. From the above, when the motor 81 of the power unit 80 is driven, the drive shaft 61 rotates to drive the chain, so that the conveyor belt 70 that connects the upper heating plate 75 in a belt shape is X in the main body casing 20. Circulate drive in the direction. The power device 80 and the upper conveyor (excluding the conveyor belt 70) 60 correspond to the “second drive device” of the present invention.

  Further, as shown in FIG. 3, a second rail 77 is attached in the main body casing 20 so as to be positioned above the first rail 57. Like the first rail 57, the second rail 77 extends horizontally in the X direction, and a pair of second rails 77 are attached to both sides in the Y direction. The roller 67 of the chain 65 rolls on the lower surface of the second rail 77. By doing in this way, it becomes possible to keep the posture of the upper heating plate 75 fed forward in a horizontal manner.

  The upper conveyor 60 and the lower conveyor 40 are synchronously driven (because the motor 81 is commonly used), and when the conveyors 40 and 60 are driven, the lower heating plate 55 is driven. The upper heating plate 75 is sent so as to overlap the upper surface. In the present embodiment, the upper heating plate 75 is pressed downward by a pressing device 90 described below.

  A plurality of (in this example, five) pressing devices 90 are provided in the longitudinal direction of the second rail 77. Each pressing device 90 includes a holding member 91 fixed to the main body casing 20 and a shaft member 93 that is coupled to the holding member 91 with a screw and has a pressing spring 95 at the tip. The pressing device 90 is located above the second rail 77, a pressing spring 95 at the tip is abutted against the second rail 77, and presses the second rail 77 downward. By adopting such a configuration, it becomes possible to hold down the upper heating plate 75 that is sequentially fed so as to overlap the upper surface of the lower heating plate 55, and it is possible to maintain the superposition state of both the heating plates 55 and 75. ing. The reason why the holding member 91 and the shaft member 93 are coupled by a screw is to adjust the pushing force of the upper heating plate 75 by the pressing device 90 by adjusting the screwing amount.

  Next, the heating device 100 will be described. The heating device 100 includes a plurality of lower heaters 110 and a plurality of upper heaters 120. Both heaters 110 and 120 are ceramic heaters in which a heater resistor is provided inside a ceramic plate excellent in electrical insulation. As shown in FIG. 9, the lower heater 110 is mounted in the main body casing 23 with the heating surface facing upward (specifically, via a support member 118 fixed to the main body casing 20). Attached). The lower heater 120 is configured to heat the lower heating plate 55 from below. On the other hand, the upper heater 120 is attached above the lower heater 110 with the heating surface facing downward (specifically, it is attached via a support member 128 fixed to the main body casing 20). ). The upper heater 120 is configured to heat the upper heating plate 75 from the upper side. In this embodiment, the surface temperatures of both heaters 110 and 120 are approximately 650 ° C., and both heating plates 55 and 75 are heated to approximately 180 ° C.

  Then, as shown in FIG. 5, the lower heater 110 is arranged in a line on both ends in the Y direction of the lower heating plate 55, and both ends in the Y direction of the lower heating plate 55 that are sequentially fed in the X direction. It is the structure which heats. Further, as shown in FIG. 6, the upper heater 120 is arranged in a line at both ends in the Y direction of the upper heating plate 75, and heats both ends in the Y direction of the upper heating plate 75 fed forward in the X direction. It has a configuration.

  By adopting such a heater arrangement, it becomes possible to apply the heat of the heaters 110 and 120 almost continuously to both ends of the heating plates 55 and 75 sent in the X direction. Both ends can be heated intensively. In other words, both end sides of the heating plates 55 and 75 are difficult to cool. For example, as shown in FIG. 7, when the heaters 110 and 120 are oriented in the same direction as the heating plates 55 and 75, the entire heating plates 55 and 75 can be evenly heated by the heaters 110 and 120. However, the heat of the heaters 110 and 120 is only intermittently applied to the heating plates 55 and 75 sent in the X direction. Since the heating plates 55 and 75 are cooled from both ends between the heaters, in the case of the arrangement shown in FIG. 7, the temperature tends to decrease on both sides of the heating plates 55 and 75. In this embodiment, since the heaters 110 and 120 are disposed at both ends of the heating plates 55 and 75, it is difficult to cool both ends. Therefore, the plate temperatures of the heating plates 55 and 75 can be made substantially uniform over the entire width in the Y direction.

  Further, the lower heater 110 is arranged in five stages as shown in FIG. 5, and the first to third stages corresponding to the head in the X direction have three places in the middle of the Y direction on both sides of the lower heating plate 55. The lower heater 110 is arranged on the front side. Further, the upper heater 120 has a four-stage arrangement as shown in FIG. 6, and the upper stage and the second stage at the head in the X direction are arranged at the upper and lower three positions in the middle of the upper side of the upper heating plate 75. A heater 120 is disposed.

  By setting it as such a heater arrangement | positioning, it becomes possible to prevent the fall of the temperature (room temperature) of the entrance part (refer FIG. 4) of the baking chamber 30 mentioned later. This is because when heated by a heater, moisture contained in the raw material of the baked confectionery evaporates and takes heat of vaporization from the surroundings. For this reason, if the heating power of the heaters 110 and 120 is weak, the temperature tends to decrease. In this regard, as described above, if a large number of heaters are arranged on the leading (first stage) side in the feed direction, the thermal power increases accordingly, so that a temperature drop can be prevented. Further, among the lower heaters 110, the heaters 110 on both sides in the Y direction are at the same position in the X direction if they are the same stage. On the other hand, as shown in FIG. 5, the heater 110 arranged in the middle is shifted in the X direction with respect to the heaters 110 on both sides (the same applies to the upper heater 120). By adopting such a configuration, the distance between the heaters 110 (distance to the heaters in the adjacent stages) is reduced, so that the whole of both ends from the center of the heating plate 55 can be heated with good balance.

  Further, reference numeral 150 shown in FIG. 4 is a preheating heater for preheating the lower heating plate 55. The preheater 150 is on the lower rear side of the disc wheel 44 and, like the lower heater 110, heats (preheats) both end portions in the Y direction of the lower heating plate 55 forwardly fed in the X direction. It has become. In the electric continuous baking machine 10, the preheating heater is provided only on the lower heating plate 55 side, but it may be provided on the upper heating plate 75 side in addition to the lower heating plate 55 side. Good.

  As shown in FIG. 8, for example, a foamed phenol resin-based or glass-based heat insulating material 27 is attached to the back surface of each closing plate 25 that closes the window 24 of the main body casing 20 (frame 23). When each closing plate 25 is attached to the window 24 of the main body casing 20 (frame 23), the heat insulating material 27 fits into the window 24 and the heat of the heaters 110 and 120 escapes from the window 24 as shown in FIG. It is the composition which prevents.

  Further, as shown in FIG. 9, a stainless steel lower shielding plate 115 is attached below the lower heater 110. Specifically, the lower heater 110 is fixed to the lower surface of a metal attachment member 113 with bolts. The lower shielding plate 115 extends horizontally in the Y direction, and collectively covers the lower portions of the two lower heaters 110 arranged in the Y direction. Both sides of the lower shielding plate 115 are stepped so as to avoid interference with the first rail 57, and the flange portion 115 a formed at the edge is in surface contact with the surface of the heat insulating material 27. In addition, an inclined wall 117 is provided at the center on the lower shielding plate 115. The inclined wall 117 is inclined downward from the center of the main body casing 20 toward both sides in the Y direction. The inclined wall 117 distributes dust carried on the surface of the lower heating plate 55 to both sides in the Y direction. Providing this inclined wall 117 makes it difficult for dust to collect in the center of the lower shielding plate 115, and improves maintainability.

  A stainless steel upper shielding plate 125 is attached above the upper heater 120. Specifically, it is fixed to the upper surface of a metal mounting member 123 for fixing the upper heater 120 with bolts. The upper shielding plate 125 extends horizontally in the Y direction, like the lower shielding plate 115, and collectively covers the upper side of the two upper heaters 120 arranged in the Y direction. Further, flange portions 125 a that are bent downward are formed on both sides of the upper shielding plate 125. In addition, the upper shielding plate 125 is bent into a V-shape (bent portion 125b) at a position inside the pressing device 90. By providing the flange portion 125a and the bent portion 125b, the heat of the heater 120 is easily directed downward, so that the heat is difficult to escape upward. In addition, a box-shaped central wall 127 is provided at the center of the lower surface of the upper shielding plate 125 so as to fill a space between the left and right heaters 120.

  These lower shielding plate 115 and upper shielding plate 125 together with the heat insulating material 27 and the frame 23 that surround the sides of the heaters 110 and 120 form a firing chamber 30 (range indicated by dimension A in FIG. 9). Yes. That is, the two shielding plates 115 and 125 constitute the ceiling wall and the bottom wall of the firing chamber 30, and the heat insulating material 27 and the frame 23 constitute the side wall of the firing chamber 30, and the heater 110 is formed by these four walls. , 120 heat is confined so as not to escape to the outside.

  The lower shielding plate 115 is provided corresponding to each stage of heaters arranged in a row in the X direction. As shown in FIG. 10, the lower shielding plate 115 of each step abuts the front and rear ends, and is continuous in the X direction. Similarly, the upper shielding plate 125 is provided corresponding to each stage of heaters arranged in a row in the X direction. And as shown in FIG. 11, the upper side shielding board 125 of each step | part has faced the front-and-rear edge part, and is continuing in the X direction without a cut | interruption. By setting it as such a structure, the baking chamber 30 of each step | line is connected to one duct shape.

  A blower fan 130 is provided on the upper side of the main body casing 20 and in the center of the fourth stage of the upper heater 120. As shown in FIG. 12, the blower fan 130 is attached via an attachment member (not shown) with the blower surface facing downward. On the other hand, a circular communication hole is opened in the upper shielding plate 125 below the blower fan 130. Therefore, when the blower fan 130 is driven, air is fed into the duct-like firing chamber 30 through the communication hole, so that the duct-like firing chamber 30 faces in the front-rear direction as shown in FIG. Airflow (slightly weak airflow) is generated. With such a configuration, it becomes difficult for the confectionery raw material powder (salt content or glutamic acid) to enter the baking chamber 30 of the main body casing 20. For this reason, the heaters 110 and 120 are unlikely to deteriorate.

  In addition, since the temperature in the main body casing 20 is approximately 210 ° C. to 240 ° C., a heat dissipation measure is taken by covering the blower fan 130 with a metal case or a fan motor is installed outside the main body casing 20. It is preferable to carry out.

  Moreover, the code | symbol 28 shown in FIG. 9 is a reinforcement member, and the code | symbol 97 is a guide member. Reinforcing members (square tube-shaped pipes) 28 are formed on the left and right sides (both sides in the Y direction) of the frame 23 and are formed over the entire length of the frame 23 (the total length in the X direction). The frame 23 is connected to the front wall and the rear wall. The reinforcing member 28 functions to increase the rigidity of the frame 23. The guide member 97 guides the lower heating plate 55 and the upper heating plate 75 from both sides in the Y direction to prevent the heating plates 55 and 75 from being displaced in the Y direction. The guide member 97 has a disk shape when viewed from the plane direction, and is configured to rotate about the axis when both the heating plates 55 and 75 are sent in the X direction.

2. Operation and Effect of Electric Continuous Baking Machine 10 The raw material of the baked confectionery is fed from the raw material charging port formed on the front side of the electric continuous baking machine 10 to the baking chamber 30 in the main body casing 20 by the lower conveyor 40. Specifically, it is placed in a line at regular intervals on the upper surface of the lower heating plate 55 of the lower conveyor 40 and sent to the baking chamber 30.

  The upper conveyor 60 is circulated and driven in synchronization with the lower conveyor 40, and each upper heating plate 75 of the upper conveyor 60 is provided near each entrance of the baking chamber 30 on each lower heating plate 55 of the lower conveyor 40. Overlap. Therefore, the raw material of the confectionery is sent to the rear of the baking chamber 30 in the X direction while being sandwiched between the two upper and lower heating plates 55 and 75.

  The raw material sandwiched between the two heating plates 55 and 75 is heated and fired by the two heating plates 55 and 75 in the process of being sent through the combustion chamber 30. Thereafter, when the outlet of the baking chamber 30 is reached, the upper heating plate 75 overlapping the upper surface of the lower heating plate 55 is automatically separated. The baked goods arranged on the upper surface of the lower heating plate 55 are then paid out by a dispenser 29 provided behind the exit of the baking chamber 30.

  According to the electric continuous baking machine 10, by continuously charging the raw materials, it is possible to continuously produce baked confectionery such as shrimp rice crackers and squid rice crackers, and the production efficiency of baked confectionery is high. . Further, since the raw material (starch) is sandwiched between the two heating plates 55 and 75 and baked, it is possible to suppress the swelling of the raw material. Moreover, since the upper heating plate 75 is pressed by the pressing device 90 via the second rail 77, the effect of suppressing the swelling of the raw material is high, and the thickness of the baked confectionery can be made constant. Therefore, it is possible to produce a high quality baked confectionery, and the yield is good.

  Further, according to the electric continuous baking machine 10, as shown in FIG. 5, the lower heaters 110 are arranged in a row at both ends in the Y direction of the lower heating plate 55, and are sequentially fed in the X direction. The side heating plate 55 is configured to heat both end portions in the Y direction. Further, as shown in FIG. 6, the upper heater 120 is arranged in a row at both ends in the Y direction of the upper heating plate 75, and both ends in the Y direction of the upper heating plate 75 fed in the X direction are heated. It has become.

  By setting it as such a heater arrangement | positioning, the both ends of each heating plate 55 and 75 can be heated preferentially, and the temperature fall of both ends can be prevented. For example, as shown in FIG. 7, when the heater 110 is oriented in the same direction as the heating plates 55 and 75, the entire heating plates 55 and 75 can be evenly heated by the heater 110. However, since the heating plates 55 and 75 are cooled from both ends, the temperature tends to decrease on both sides of the heating plates 55 and 75 when arranged as shown in FIG. In this embodiment, since the heaters 110 are disposed at both ends of the heating plates 55 and 75, it is difficult to cool both ends, and it is possible to sufficiently heat (fire) the raw material at that portion. Therefore, almost no defective products that are insufficiently baked are produced, and the production efficiency (yield) of baked confectionery is high.

  When heated, the moisture contained in the raw material of the baked confectionery evaporates and takes the heat of vaporization from the surroundings. Therefore, if the heating power of the heaters 110 and 120 is weak, the temperature is likely to decrease at the entrance portion of the baking chamber 30. In this regard, according to the electric continuous baking machine 10, the lower heater 110 is arranged in five stages as shown in FIG. 5, and the lower heating plate is arranged in the first to third stages corresponding to the head in the X direction. The lower heaters 110 are arranged at three positions in the middle of 55 in the Y direction. Further, the upper heater 120 has a four-stage arrangement as shown in FIG. 6, and the upper stage and the second stage at the head in the X direction are arranged at the upper and lower three positions in the middle of the upper side of the upper heating plate 75 in the Y direction. A heater 120 is disposed.

  By adopting such a heater arrangement, the heating power of the entrance portion of the baking chamber 30 becomes strong, so that it is possible to prevent a decrease in temperature (room temperature). Therefore, the entire baking chamber 30 including the entrance portion is maintained at a temperature necessary for baking confectionery (for example, 210 ° C for squid rice crackers, 160 ° C for shrimp rice crackers, and 100 ° C for dough baking for twice-baked rice crackers). It becomes possible. Therefore, it becomes possible to increase the productivity of baked confectionery. Further, the number of heaters can be reduced and power consumption can be suppressed as compared with the case where three heaters are arranged for all stages.

Moreover, according to this electric continuous baking machine 10, the baking chamber 30 is formed by the shielding plates 115 and 125, the heat insulating material 27, and the frame 23, and the heat of the upper and lower heaters 110 and 120 is confined in the room. It is like that. Therefore, heat utilization efficiency is high, and it is possible to suppress power consumption.

The electric continuous baking machine 1 is capable of producing a variety other than shrimp crackers and squid crackers.

(2) In the above embodiment, with respect to the lower heater 110, the first to third stages corresponding to the head in the X direction are arranged with the heater 110 in the middle in addition to the both sides of the lower heating plate 55 (three places are arranged). did. In addition, for the upper heater 120, the first stage and the second stage, which are the head in the X direction,
In addition to the both sides of the upper heating plate 75, the heaters 110 are arranged in the middle (three places are arranged). It is only necessary that three heaters are arranged at least in the first stage in the X direction, and whether or not three heaters are arranged in other stages may be determined in consideration of the temperature distribution in the firing chamber. In addition, the reason for arranging three heaters in the first stage is that the heat of vaporization of moisture contained in the raw material is taken into consideration, so that the moisture contained in the raw material is small and the heat of vaporization is expected to be small. The central heater may be abolished or stopped.

  (3) In the above-described embodiment, the example in which the blower fan 130 is provided in the main body casing 20 has been described. However, if the deterioration of the heaters 110 and 120 is not taken into consideration, it can be eliminated. Further, if it is possible to suppress the swelling of the raw material by the weight of the upper heating plate 75, the pressing device 90 may be eliminated.
