Etc. are removed and washed.

Next, the operation of the caramelizing heater 100 will be described with reference to FIGS.
Referring to FIG. 3, in the caramelizing heater 100, when the electric motor 102e is turned on by the operator on the control / operation panel 101a, the electric motor 102e is activated and the drive pulley 102c is rotated. The conveyor belt 102a advances so as to circulate counterclockwise on the paper surface, and proceeds from the start point side to the end point side in the direction of the white arrow on the paper surface in the transport unit 102a1. In parallel with this, in the control / operation panel 101a, the traveling speed of the conveyor belt 102a is set by the operator, and the conveyor belt 102a advances at the set speed.
In the control / operation panel 101a, when the operator turns on the first heating device 111, the second heating device 112, the third heating device 113, and the fourth heating device 114, the first heater unit 111a, Electric power is supplied to the heater unit 112a, the third heater unit 113a, and the fourth heater unit 114a, and the heaters 111d, 111e, 112d, 112e, 113d, and 114d generate heat, and heat rays are irradiated downward. In parallel with this, on the control / operation panel 101a, the operator sets the heat generation temperatures of the first heater unit 111a, the second heater unit 112a, the third heater unit 113a, and the fourth heater unit 114a.

  Furthermore, the first heater unit 111a and the second heating device 112 of the first heating device 111 are set so that the temperature detected by the first temperature sensor 121 becomes the first predetermined temperature t1 ° C. by the operator of the caramelizing heater 100. The heating temperature and the vertical position of the second heater section 112a are adjusted. That is, the operator adjusts the heat generation temperatures of the first heater unit 111a and the second heater unit 112a so that the temperature detected by the first temperature sensor 121 is close to the first predetermined temperature t1 ° C. Further, the operator holds the first handle portion 111c of the first heating device 111 and the second handle portion 112c of the second heating device 112 so that the detected temperature of the first temperature sensor 121 becomes the first predetermined temperature t1 ° C. Operate to adjust the vertical position of the first heater part 111a and the second heater part 112a. Therefore, in the temperature adjustment described above, the adjustment of the heat generation temperature of the first heater unit 111a and the second heater unit 112a is used for temperature adjustment over a wide range, and the adjustment of the vertical position is used for fine adjustment of the temperature. ing.

Similarly, the third heater unit 113a and the fourth heating of the third heating device 113 are adjusted so that the temperature detected by the second temperature sensor 122 becomes the second predetermined temperature t2 ° C. by the operator of the caramelizing heater 100. The heating temperature and the vertical position of the fourth heater portion 114a of the device 114 are adjusted.
The second predetermined temperature t2 ° C is set lower than the first predetermined temperature t1 ° C. The first predetermined temperature t1 ° C and the second predetermined temperature t2 ° C are based on the material of the wafer 1, the traveling speed of the conveyor belt 102a, and the like. Is set. For example, in the present embodiment, the first predetermined temperature t1 ° C. is 220 ° C., and the second predetermined temperature t2 ° C. is 160 ° C.

At this time, the wafer 1 that has been transported by the spreader 14 and on which the sugar seasoning 2 (see FIG. 4) has been spread is spread from the spreader 14 to the beginning of the transport section 102a1 of the transport conveyor 102 adjacent thereto. The sheet is conveyed and conveyed by the conveyor belt 102 a in the direction of the white arrow on the paper surface, which is the conveying direction, and passes through the heating space 103 a inside the heating chamber 103.
In the heating space 103a, the wafer 1 sequentially passes below the first heating device 111, the second heating device 112, the third heating device 113, and the fourth heating device 114, and in the process of passing below these, The heating device 111, the second heating device 112, the third heating device 113, and the fourth heating device 114 are sequentially and continuously heated.

  In the process of passing under the first heating device 111 and the second heating device 112, the sugar seasoning 2 (see FIG. 4) on the wafer 1 is heated at a first predetermined temperature t1 ° C., which is a higher temperature, After melting and becoming liquid or gel and spreading over the entire upper surface of the wafer 1, it is in a caramel state, and the surface is baked and characterized to form the sugar layer 3. At this time, in the sugar layer 3, a characterized layer generated by scorching the sugar is formed on the surface portion. Therefore, below the first heating device 111 and the second heating device 112, the sugar seasoning 2 is melted on the surface of the wafer 1, and the sugar layer 3 whose surface is characterized is formed.

  When the wafer 1 is transported from below the first heating device 111 and the second heating device 112 to below the third heating device 113, the second predetermined temperature t2 ° C, which is lower than the first predetermined temperature t1 ° C. Is heated. For this reason, in the process of passing under the third heating device 113 and the fourth heating device 114, the wafer 1 is baked while suppressing the progress of scorching on the surface of the sugar layer 3, and the inside of the sugar layer 3. Is also characterized, whereby the entire sugar layer 3 is characterized. Therefore, under the third heating device 113 and the fourth heating device 114, the finish firing inside the sugar layer 3 is performed in the wafer 1.

  Even when the wafer 1 and the sugar layer 3 are heated at the first predetermined temperature t1 ° C. and the second predetermined temperature t2 ° C., the wafer 1 depends on the ambient environment such as air temperature and humidity, the traveling speed of the conveyor belt 102a, and the like. The speed at which the upper sugar layer 3 is characterized changes. For this reason, in the process in which the wafer 1 passes through the heating space 103a, the operator outside the caramelizing heater 100 and the wafer 1 passing under the second heating device 112 from the first observation window 103f and above the wafer 1 The state of the sugar layer 3 is confirmed, and the state of the wafer 1 passing under the fourth heating device 114 from the second observation window 103g and the state of the sugar layer 3 thereon are confirmed.

At this time, for example, when the surface of the sugar layer 3 on the wafer 1 confirmed from the first viewing window 103f is in a liquid or gel state without being characterized, the operator The first heater unit 111a or the second heater unit 112a of the second heating device 112 is lowered downward to reduce the distance to the transport unit 102a1, and the heating temperature of the wafer 1 is increased. Further, when it is necessary to greatly increase the heating temperature of the wafer 1, the heat generation temperature of the first heater unit 111a or the second heater unit 112a is also increased in parallel.
On the other hand, when excessive scorch is formed on the surface of the sugar layer 3, the operator raises the first heater part 111a or the second heater part 112a upward to increase the distance from the transport part 102a1, The heating temperature of the wafer 1 is lowered. Further, when it is necessary to greatly reduce the heating temperature of the wafer 1, the heat generation temperature of the first heater portion 111a or the second heater portion 112a is also lowered in parallel.

In addition, when excessive scoring is formed on the surface of the sugar layer 3 on the wafer 1 confirmed from the second viewing window 103g, the operator can use the third heater portion 113a of the third heating device 113 or the fourth heating by the operator. The fourth heater unit 114a of the apparatus 114 is raised upward to increase the distance from the transport unit 102a1, and the heating temperature of the wafer 1 is decreased. Further, when it is necessary to greatly reduce the heating temperature of the wafer 1, the heat generation temperature of the third heater portion 113a or the fourth heater portion 114a is also lowered in parallel.
On the other hand, if the surface of the sugar layer 3 is not sufficiently burned, that is, if the state of caramelization is not a predetermined one, the third heater portion 113a or the fourth heater portion 114a is lowered downward to increase the distance from the transport portion 102a1. The heating temperature of the wafer 1 is increased. Further, when it is necessary to greatly increase the heating temperature of the wafer 1, the heat generation temperature of the third heater portion 113a or the fourth heater portion 114a is also increased in parallel.

  Therefore, in the heating space 103a of the heating chamber 103, the wafer 1 is subjected to a stepwise heating process provided for melting the sugar seasoning 2 (see FIG. 4) and forming the characterized sugar layer 3. The sugar layer 3 whose surface and inside are uniformly characterized is formed.

The wafer 1 that has passed under the fourth heating device 114 is transported to the outside of the heating chamber 103 by the conveyor belt 102a, and is sent to the adjacent second mesh conveyor 16 at the end of the transport section 102a1.
In addition, the sugar seasoning 2 (see FIG. 4) melts by heating in the heating chamber 103 and may adhere to the conveyor belt 102a by spilling from the wafer 1 onto the conveyor belt 102a in the process of characterizing. On the top, debris such as burrs on the periphery of the wafer 1 may fall and adhere. The fragments of the wafer 1 and the sugar seasoning 2 adhering to the conveyor belt 102a are washed away by the cleaning liquid flowing in the cleaning tank 101b when the conveyor belt 102a passes through the cleaning tank 101b.

  As described above, the caramelizing heater 100 according to the present invention is for firing the sugar seasoning 2 sprayed or applied to the wafer 1. Further, the caramelizing heater 100 includes a transport unit 102a1, and heats the transport unit 102a1 and transports the wafer 1 along the transport unit 102a1, and changes the distance between the transport unit 102a1.

  As a result, the first heating device 111 and the second heating device 112, and the third heating device 113 and the fourth heating device 114 adjust the distance from the transport unit 102a1, thereby the wafers transported in the transport unit 102a1. The temperature at which 1 is heated can be adjusted. Furthermore, since it heats using the 1st heating apparatus 111, the 2nd heating apparatus 112, the 3rd heating apparatus 113, and the 4th heating apparatus 114 which were provided along the conveyance part 102a1, the sugar seasoning on the wafer 1 is carried out. 2 can be heated for a long time, whereby the heating temperature can be kept low. Therefore, the sugar seasoning 2 is heated without excessively degrading its quality, and the wafer 1 under the sugar seasoning 2 is excessively heated without degrading its quality. 2 can be heated to form a uniform caramelized sugar layer 3. Therefore, the caramelize heating machine 100 allows the sugar seasoning 2 on the wafer 1 to be baked without impairing the quality of the sugar seasoning 2 and the wafer 1.

  In the caramelizing heater 100, in particular, the heating temperature by the first heating device 111 and the second heating device 112 positioned on the upstream side in the transport direction of the transport conveyor 102 is increased, and the third temperature positioned on the downstream side. By reducing the heating temperature by the heating device 113 and the fourth heating device 114, the sugar seasoning 2 on the wafer 1 can be uniformly baked over its surface and inside.

  The third heating device 113 and the fourth heating device 114 generate a lower amount of heat than the first heating device 111 and the second heating device 112. Thereby, since the heating temperature by the 3rd heating apparatus 113 and the 4th heating apparatus 114 can be adjusted lower, a saccharide seasoning is suppressed, suppressing progress of baking of the surface of the saccharide seasoning 2 on the wafer 1. 2 can be sufficiently fired.
