DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic food heating and baking method, and more particularly, to a method for baking automatically with little modification to a conventional baking apparatus.

[0002]

2. Description of the Related Art Generally, regardless of Japanese confectionery and Western confectionery foods, most confectioneries and foods are continuously heated and baked by mass-production baking equipment after dough adjustment, and are automatically mass-produced. Various types of mass-production sintering apparatuses have been proposed and implemented.
It is of the type described in JP 36883. In this type, a plate is mounted on an endless track that runs continuously or intermittently, or the plate itself is formed in an endless shape, and an endless end that runs continuously or intermittently is used. The dough is placed on the track, and the firing zones are arranged above and below the endless track. This firing zone is equipped with an electric heating element or a gas burner, and is heated by the upper and lower firing zones while the cloth placed on the endless track runs continuously or intermittently. The dough is fired automatically.

[0003] In the case of baking in this manner, the baking conditions differ depending on the type of confectionery or food, and various methods have been devised in order to set the baking conditions. It is done manually. For this reason, when the confectionery or food to be baked changes, the conditions of the gas burner and the electric heating element of the baked zone are all adjusted until the steady conditions are reached and all subsequent operations are performed. The work is extremely complicated, and particularly, this work is sometimes exposed to a high temperature, so that the degree of fatigue is extremely large, and improvement thereof is desired.

[0004] In view of the above, the present inventor has previously divided the upper and lower firing zones into at least three firing zones as disclosed in Japanese Patent Publication No. 63-66496.
We proposed a baking apparatus that changes the heating element of the fin. That is, this baking apparatus forms the first, second and third baking chambers by dividing the confectionery baking zone into at least three along the traveling direction of the common moving band, and is placed on this moving band. In the confectionery baking apparatus in which the confectionery dough is baked while sequentially passing through the respective baking chambers, the first baking chamber is provided with gas burners above and below the moving zone, and the second baking chamber is provided with the moving zone. This is a confectionery baking device in which a gas burner is provided in the lower part while an electric heating element is provided in the upper part, and an electric heating element is provided in the upper and lower part of the moving zone in the third baking chamber.

[0005] However, this apparatus is intended to bake according to the type of confectionery while making use of the characteristics of the confectionery by changing the heating element of each baking zone. That is, there is a great advantage in expanding the range of confectionery to be targeted. However, taking one confectionery as an example, the setting of the conditions for baking the confectionery all depends on the manual operation, and there is no substitute for the setting described above, and there is a need for improvement.

[0006] Therefore, it is conceivable to apply an electric computer technology to these manual operations to make them unmanned or automated. In these applications, it is necessary to improve the firing apparatus itself and to apply it according to the improvement. However, since all of the conventional firing apparatuses have been developed on the premise of manual labor as described above, it is almost impossible to apply them as they are.

[0007]

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned drawbacks and can be applied to conventional baking apparatuses without any modification, and can be applied to the baking conditions of food or confection to be baked. The present invention proposes an automatic food heating and baking method that can be controlled by using computer technology, with little dependence on manual work.

[0008]

That is, according to the method of the present invention, upper and lower firing zones are formed above and below an endless track that runs continuously or intermittently from an inlet to an outlet in a horizontal firing furnace, Each of these upper and lower firing zones is divided into at least two blocks, and at least two heating elements are arranged in each of these blocks, while these heating elements are individually activated by a command from the control storage device. In an automatic food heating and firing method in which food placed on an endless track is automatically heated and fired,
In the control storage device, a reference temperature for each block set according to the food to be baked and a buffer temperature range set based on the reference temperature are input and stored in advance, while each heating element in each block is stored. An operation pattern in which the operation mode is individually determined is input and stored in advance, and thereafter, during the food baking operation, the operating temperatures of the upper and lower blocks are detected and input to the control storage device, and the control storage device is operated. In the above, the food is heated and baked by calculating based on the detected temperature and the operating pattern, the reference temperature and the buffer temperature range preliminarily input and stored, and giving an operation command to each heating element to control the heating element. It is characterized by.

Hereinafter, the configuration as the means of the present invention and the operation thereof will be described as follows.

First, in FIG. 1, reference numeral 1 denotes a horizontal firing furnace, in which a firing zone is formed. An endless track 2 is disposed through the firing zone, and this endless track 2 is, for example, as shown in FIG.
It travels continuously or intermittently from the inlet to the outlet, on which confectionery or food dough is placed and fired. In the firing furnace 1, upper and lower firing zones 3, 4 are formed vertically above and below the endless track 2 running in such a manner, and these upper and lower firing zones 3, 4 are vertically arranged. Each is divided into at least two blocks in the running direction by a corresponding partition (see FIG. 1). Incidentally, in the example shown in FIG. 1, the upper sintering zone 3 is divided into three blocks 31, 32 and 33 by two partitions, and corresponds to the upper and lower partitions which divide the upper sintering zone 3 vertically. The lower firing zone 4 is divided into three blocks 41, 42, 43 by two partition walls. Each of the upper and lower blocks 31, 32, 33, 41, thus divided,
Heating elements 311, 312, 32
1,322,323,324,331,332,33
3, 411, 412, 413, 414, 421, 42
2, 431, 432 are provided, and the dough such as confectionery and food placed on the endless track 2 is heated from above and below by these heating elements and is continuously baked.

In addition, each of the blocks 31, 3
In 2, 33, 41, 42, and 43, for example, an operating pattern for each heating element such as a gas burner or an electric heating element is described based on the operating mode and use conditions.
The operation patterns are individually set, and the set operation patterns are input to the control storage device 5 in advance as information of each heating element.

That is, the upper and lower blocks 31, 3
The reference temperatures of 2, 33, 41, 42, and 43 are obtained from the temperature curves required for confectionery and food to be baked, and are provided inside the upper and lower blocks 31, 32, 33, 41, 42, and 43. With respect to the heating element, the operation pattern is set based on the operation mode or the use condition, and is input to the control storage device 5. For example, when baking a shoe of a shoe cream, each block 31, 32, 33, 41, 4
The reference temperatures of 2, 43 were 160 ° C., 170 ° C., 2
The temperature is set to 00 ° C., 200 ° C., 180 ° C., and 160 ° C., and input to the control storage device 5. At this time, a buffer temperature range is defined for each block around the set reference temperature, and the block is input to the control storage device 5. The buffer temperature range is determined according to the confectionery or food to be baked, but is usually set to ± 5 ° C. or less. For the individual heating elements arranged in the upper and lower blocks, the operation patterns of A, B, C, D, and G are set as follows based on the operation mode and use conditions. These are input to the control storage device 5 in advance as information of each heating element. A: No matter what the detected temperature of each of the upper and lower blocks is, the operating pattern is such that the heating operation is continuously performed regardless of the value. B: The detected temperatures of the upper and lower blocks are stored in advance. An operation pattern in which the operation is turned off and the heating operation is stopped when the temperature reaches the buffer temperature range of a certain reference temperature. C: The buffer temperature of the reference temperature in which the detected temperatures of the upper and lower blocks are stored in advance. An operation pattern in which the heating operation is stopped when the vehicle enters the area; D. An operation pattern in which the operation is turned on / off from a request for temperature adjustment regardless of the detected temperatures of the upper and lower blocks. G: An operation pattern in which the heating operation is completely stopped during the operation, that is, even if the heating element disposed in the block is provided with this pattern, the operation pattern is not used during firing. Table 1, for example, shows an example of baking of a screen, which is also referred to as a screen cream skin. That is, it is not preferable to strongly heat the shoe entering from the entrance side of the firing furnace 1 by the heating elements 311 and 312 of the first upper block 31, and it is not necessary to heat much. The upper block 31 is heated to the reference temperature 16
It is sufficient if the temperature can be maintained at 0 ° C. For this reason, the operation mode of each of the heating elements 311 and 312 in the upper block 31 is set to G, and this G information is input to the control storage device 5 in advance, and
During the firing, the heating from the heating elements 311 and 312 is stopped. On the other hand, the lower surface of the shoe needs to be brought into contact with the endless track 2, that is, the baking plate as a product, and must be strongly heated from the beginning and burned. From this point, the reference temperature of the block 41 is set as high as 200 ° C. Block 4
3 heating elements 411, 4 out of 4 heating elements in 1
The operating patterns of 12 and 414 are both set to A, the operating pattern of the heating element 413 is set to C, and the A and C operating patterns are given to these heating elements. It is input to the control storage device 5. Therefore,
In the first upper block 31 and lower block 41,
When starting, the heating elements 411, 412, 413, 4
14 is turned on, and when the blocks 31 and 41 approach their respective reference temperatures, the control operation by the control storage device 5 is started. At this time, lower block 4
When the detected temperature of 1 enters the buffer temperature range determined based on the reference temperature of 200 ° C., the operation of the heating element 413 to which the operation pattern C is applied is stopped. On the other hand, as long as the lower block 41 is maintained within the reference temperature (200 ° C.), the temperature of the upper block 31 is maintained at the reference temperature (160 ° C.) To be retained in this manner, an actuation pattern is provided to the heating elements in block 41 below. However, even when such an operation pattern is provided, the temperature in the upper block 31 may be lower than the reference temperature, and the reference temperature may not be maintained. At this time, the paragraph [00]
17], when the operation pattern is changed again, the block 31 can be maintained at the reference temperature of 160 ° C.

As described above, when an operation pattern is given to each heating element and input, the baking time determined according to the food or confection to be baked, the respective blocks 31, 32, 33, 4
Since the reference temperatures of 1, 42, and 43 and the traveling speed of the endless track 2 are input in the control storage device 5 in advance, each heating element is turned on / off by a command from the control storage device 5, and confectionery or food Is fired automatically.

That is, the dough is placed on the endless track 2,
By moving the endless track 2, each heating element is turned on and off according to a predetermined program.

More specifically, during operation, the operating temperature of each block is detected by the temperature detecting elements 61, 62, 63, 64, 65 and 66 from the blocks 31, 32, 33, 41, 42 and 43, respectively. This measured temperature is input to the control storage device 5 as operation information. In the control storage device 5,
Since the above information is input and stored in advance, the control storage device 5 calculates based on these stored information and measurement information, gives an operation command to each heating element, and classifies each heating element in advance by classification input. It is turned on and off within the range determined by the operation mode and use conditions, for example, A, B, C, D, and G.

For example, in the case where the baking time is set to 15 minutes and baking of the screen for a screen is performed, a baking apparatus as shown in FIG. 1 is used, and the moving speed of the endless track is determined from the baking time. , As shown in Table 1, the reference temperature of each block,
A pattern such as an operation mode of each heating element is determined, and these conditions are input in advance to the control storage device as information.

Therefore, when starting, the heating element 3
All the heating elements except for 11, 312, 432, and 433 are turned on to perform ignition heating, and thereafter, when it is determined that each zone has approached the reference temperature, the operation is shifted to automatic operation. When the operation is shifted to the automatic operation, for example, in the lower zone on the inlet side, the reference temperature of the first block 41 is 200 ° C., the buffer temperature range is set to ± 2 ° C., and these values are stored in the control storage device 5. Has been entered. Therefore, when the temperature detected by the temperature detecting element 64 reaches 198 ° C.,
Only the heating element 413 to which the operation pattern C is applied is turned off by a signal sent from the control storage device 5. By turning on / off the heating element 413, other heating elements 411,
Although the blocks 412 and 414 are turned on and heated, the block 41 can be maintained at the reference temperature of 200 ° C. On the other hand, the detected temperature of the block 41 is lower than the buffer temperature range determined by the reference temperature, for example, 197.
When the temperature reaches ℃, the heating element 413 to which the operation pattern C is applied is turned on, the temperature rises again, and is maintained at the reference temperature. During this time, the temperature of the block 31 on the inlet side of the upper zone 3 can be maintained at the reference temperature of 160 ° C. by the upward flow from the lower block 41 immediately below. In order to satisfy such conditions, the operation patterns of the heating elements 411, 412, 413, 414 are selected and set based on the reference temperatures of the blocks 31 and 41. However, as described above, the temperature of the upper block 31 may not always be maintained at the reference temperature even if selected and set in this manner. At this time, the heating element 411,
412 and 414 operating patterns and other heating elements 413
The operation pattern is further examined, and if necessary, the buffer temperature range for each reference temperature is examined to change the operation pattern.

Each of the heating elements may be a gas burner or an electric heating element.
In addition, a gas burner or an electric heating element can be used in addition to an electric heating element in part.

The reference temperature of each block can be determined according to the type of food or confection to be baked. In addition,
In FIG. 1, reference numerals 71 and 72 are energy adjusting devices for each heating element.

At this time, each of the upper and lower firing zones is divided into at least two blocks, and a reference temperature determined in accordance with the firing conditions of the food to be fired in each of the blocks and a reference temperature related to the reference temperature. In addition to setting a buffer temperature range determined in advance, these are input and stored in the control storage device as temperature information in advance,
The operating mode of each heating element of each block is individually defined as an operating pattern, and these operating patterns are previously input and stored in a control storage device.
