Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for controlling humidity in a storage such as a deconditioner for thawing, aging and fermenting frozen bread dough.

[0002]

2. Description of the Related Art For example, a so-called deconditioner is one of the devices that can efficiently provide freshly baked bread in stores and the like. In this method, frozen bread dough is thawed for a predetermined time in a refrigerator so that the bread can be baked at a desired time, and then aging for improving the fermentation state and a proofer for actual fermentation are sequentially performed. It is. According to this, for example, a series of processing such as thawing, aging, and proofing of frozen bread dough can be automatically performed in advance at night when no workers are present, so that workers can immediately start baking bread from the early morning. Becomes possible.

[0003] In such a deconditioner, in order to perform thawing and fermentation without deteriorating the quality of the dough, it is necessary to determine not only the temperature in the refrigerator but also the humidity in accordance with the type and process of the dough. It is important to keep the appropriate condition. For this reason, for example, a frozen bread dough maker may provide an optimum humidity at the time of storage for each kind of bread dough, a so-called nominal optimum storage humidity in the form of a recipe.

It is desirable that the humidity control in the deconditioner be performed so that the humidity in the refrigerator matches the set value and that condition is maintained for a predetermined time. But,
Actually, it is unavoidable that the humidity in the refrigerator fluctuates in a certain range up and down across the set value. For this reason, it is customary to determine a center value of the target storage humidity and control the fluctuation range of the actual in-housing humidity detected by the humidity sensor to fall within a certain range from the center value. That is, the set value of the inside humidity in each step of the deconditioner means a central value of the inside humidity that varies in a certain width.

[0005]

However, even if the center value is adjusted to the above-mentioned nominal optimum storage humidity in setting the humidity in the refrigerator, the influence of the state of the wind flowing in the refrigerator, the condition before and after storage, etc. There is a problem that the storage state of the dough in each process is not always optimal. Specifically, for example, even if the storage humidity is set to the nominal optimum storage humidity, the bread dough may not be able to be maintained in a good state depending on the state of the wind flowing in the refrigerator. Also, the value of the optimum humidity at the time of storage may vary depending on the time during which the dough was kept outside the storage before storage, or the length of time from being taken out of the storage to baking. As described above, the actual working conditions such as the type of the deconditioner used and the amount of time the bread dough is outside the storage before and after storage vary depending on the individual user or the store. Even if the set value of the humidity in the refrigerator is adjusted to the nominal optimum storage humidity determined by assuming the conditions, the bread dough cannot always be stored in an optimum state.

[0006] As a method of avoiding the above-mentioned problem, the inside humidity is not always adjusted to the nominal optimum storage humidity when setting the inside humidity, but the inside humidity is set so that an optimum state is obtained for each case. May be changed. However, it is difficult to determine concretely the set value of the humidity in the refrigerator in accordance with each work environment and work conditions without a considerable skill or experience. Even if the humidity in the refrigerator is set to an appropriate value in this way, workers who are not very familiar with the operation of the deconditioner, for example, workers such as part-timers and part-time workers, will not be able to set the humidity in the refrigerator. Is different from the nominal optimum storage humidity described in the recipe, it is often anxious about itself.

Therefore, while the set value of the humidity in the refrigerator is set to the value of the nominal optimum storage humidity, the ratio of the on / off time of the humidifier provided in the deconditioner, that is, the duty ratio is changed to change the ratio. The humidity in the refrigerator may be substantially corrected by appropriately adjusting the humidification amount.
However, at present, for example, the humidifier is arranged in the machine storage space at the top of the deconditioner main body, and besides directly operating the operation unit of the humidifier in a place where it can not be easily operated from the outside Since there is no means for adjusting the humidification amount, there is a problem that the operability at the time of adjusting the humidification amount is extremely poor.

As described above, in order to provide the user with a sense of security, it is necessary to adjust the apparent set value of the internal humidity to the nominal optimal storage humidity. On the other hand, in order to properly thaw and ripen frozen bread dough, it is important not to always keep the actual humidity in the refrigerator at the nominal optimum storage humidity, but to appropriately correct it according to individual circumstances. It is necessary to easily adjust the volume. In addition, as described above, the problem is not limited to the case of the deconditioner, but may be applied to other types of storage such as a refrigerated (frozen) storage or a hot storage that requires keeping the humidity in the storage in a predetermined state. Can naturally occur.
The present inventors have proposed the present invention from such a viewpoint.

[0009] That is, an object of the present invention is to substantially adjust the humidification amount of a humidifier so as to obtain a desired storage state without changing the humidity in the refrigerator one by one. It is an object of the present invention to provide a humidity control device in a storage, which can be corrected or fine-tuned, and in which such a humidification amount can be adjusted more easily than in the past.

[0010]

The present invention is characterized in that a device for controlling the humidity in a storage such as a deconditioner for defrosting, aging and fermenting frozen bread dough is constructed as follows.

That is, as shown in FIG. 1, humidity detecting means A for outputting a signal indicating the current humidity in the refrigerator, humidity setting value input means B for inputting a set value of the humidity in the refrigerator, Humidifying means C for humidifying the air, and humidifying amount set value input means D for inputting a set value of the humidifying amount by the humidifying means C
Mode switching means E for switching between a mode in which a set value of the humidity in the refrigerator can be input and a mode in which a set value of the humidification amount can be filtered; and setting of the humidity set value and the humidification amount in the refrigerator. Display means F for displaying the values; storage means G for storing the input set values of the in-compartment humidity and the humidification amount and a predetermined standard humidification amount;
And a control means H for controlling the humidification means C.

The control means H receives the outputs from the humidity detecting means A, the humidity set value input means B, the humidification set value input means D and the mode switching means E, and switches the display on the display means F. It has become. Then, in a state where the settings of the in-compartment humidity and the humidification amount are completed, the control means H reads out the contents stored in the storage means G, and when the set value of the humidification amount indicates the standard humidification amount, The humidification amount of the humidification unit C is controlled so that the actual humidity in the refrigerator matches the set value. When the set value of the humidification amount does not indicate the standard humidification amount, the humidification amount is set in advance according to the set value of the humidification amount. The humidification amount of the humidification unit C is controlled so that the actual in-compartment humidity becomes larger or smaller than the set value by a predetermined amount.

[0013]

In the humidity control apparatus according to the present invention, the set value of the humidity in the refrigerator can be inputted by the humidity set value input means B in a mode in which the humidity of the refrigerator can be inputted. When the mode is switched to a mode in which the set value of the humidification amount can be input by the mode switching means E from the state, the set value of the humidification amount can be input by the humidification amount set value input means D. The set values of the in-compartment humidity and the set value of the humidification amount thus input are respectively stored in the storage means, whereby the respective settings of the in-compartment humidity and the humidification amount are completed.

When the setting is completed, the control section H reads out the contents stored in the storage means, and when the set value of the humidification amount indicates the standard humidification amount stored in advance in the storage means, the control section H reads the actual humidification amount. The humidification amount of the humidification unit C is controlled so that the humidity in the refrigerator matches the set value. Also,
When the set value of the humidification amount does not indicate the standard humidification amount, the actual internal humidity is set to be larger or smaller than the set value by a predetermined amount predetermined according to the set value of the humidification amount. , The amount of humidification of the humidifier C is controlled.

Thus, according to the present invention, both the setting of the humidity in the refrigerator and the setting of the humidification amount can be performed only by switching to the predetermined mode and inputting each set value. Therefore, the operation of adjusting the humidification amount can be performed extremely easily as compared with, for example, a conventional deconditioner in which the humidification amount is adjusted by directly operating the humidifier. In addition, even if the set value of the humidity in the refrigerator is substantially changed by adjusting the humidification amount, for example, the humidity in the refrigerator set in accordance with the nominal optimum storage humidity described in the recipe is apparently the same. Since the set value of the humidity in the refrigerator is displayed as it is on the display means F without being changed, there is no concern for a person who is not very familiar with the operation of the storage such as a deconditioner.

Then, after the mode on the screen is switched to the next predetermined mode via the control unit 19, the setting items in the switched mode can be input. The mode switching means 24 in the present invention is constituted by the mode button 24.

Next, the operation of setting the above-mentioned internal humidity and the like will be described. Mode button 24 in setting value input section 17
Is pressed to select, for example, a mode (hereinafter, referred to as a humidity setting mode) that enables input of a set value of the humidity in the refrigerator with respect to the operation of the upper chamber, and the screen of the display unit 16 displays
As shown in FIG. 4, predetermined setting items and setting values are displayed, and a specific one of them (in the example, the internal temperature) waits for a setting value. The item waiting for the input of the setting value is indicated by, for example, a cursor being placed on the setting value or a flashing of the setting value. Then, the user operates the up button 21 and the down button 22 of the set value input unit 17 while looking at the screen to input the set value of the item waiting for input. After that, when the set button is pressed, the input set value is determined, and the set value of the next predetermined item (in the example, the humidity in the refrigerator) waits for input, so that the desired set value ( For example, enter the nominal optimal storage humidity). When the input of all the setting values is completed in this way, the mode button 24 is pressed. Thereby, the setting of each item in the humidity etc. setting mode is completed, and the screen is switched to a predetermined mode. At this time, the set value of the in-compartment humidity is stored in the first storage area 18a of the storage unit 18 described above.

On the other hand, when the mode button 24 is pressed to switch to a mode in which a set value of the humidification amount can be input (hereinafter, referred to as a humidification amount setting mode), the screen of the display unit 16 is displayed as shown in FIG. , Automatic operation (automatic thawing, aging,
The set value of the humidification amount of the humidifier 15 into the compartment a by the humidifier 15 is displayed as an item to be set in the operation mode in which the humidifier 15 is operated. In this example, the set value of each humidification amount is
On the basis of the value 0 at the center of the scale displayed on the screen of the display unit 16, from the scale 1 on the + side (the side increasing the humidification amount) and the − side (the side decreasing the humidification amount), Up to 3 can be adjusted by a predetermined amount in three steps. When inputting the set value of the humidification amount, the user operates the up button 21 or the down button 22 of the set value input unit 17 to move the cursor on the screen to any scale, and then presses the set button 23. Thus, the set value of the humidification amount input for the operation mode is determined. After setting the humidification amount in this way, if the mode button 24 is pressed, the setting is completed, and the screen is switched to a predetermined mode.
At this time, the input set value of the humidification amount is stored in the second storage area 18b of the storage unit 18 described above.

In addition to the above, in the in-compartment humidity control device of the present invention, the control unit 19 is configured to perform the following control on the humidifier 15. That is, when the mode button 24 is pressed, the control unit 19
When receiving the signal indicating the completion of the setting operation output from
The contents stored in the first to third storage areas 18a to 18c of the storage unit 18 are read out, and the set value of the humidification amount stored in the second storage area 18b is stored in the third storage area 18c. It is determined whether or not the specified standard humidification amount is indicated. When the set value of the humidification amount indicates the standard humidification amount, that is, when the set value of the humidification amount in FIG.
The humidification amount of the humidifier 15 is controlled so as to match the set value (set value of the humidity in the refrigerator) stored in 8a. Also,
When the set value of the humidification amount stored in the second storage area 18b does not indicate the standard humidification amount, that is, when the set value of the humidification amount in FIG. Controls the humidification amount of the humidifier 15 such that the actual in-compartment humidity becomes larger or smaller than the set value by a predetermined amount predetermined according to the set value.

According to the deconditioner 1 configured as described above, the mode is switched by the mode button 24 as appropriate, so that the interior humidity and the like are set in the interior humidity setting mode shown in FIG. In the humidification amount setting mode shown, the humidification amount can be set. At this time, the set value of the chamber humidity is stored in the first storage area 1 of the storage unit 18.
The setting value of the humidification amount is stored in the second storage area 18b of the storage unit 18. When the setting in each mode is completed, the control unit 19 reads out the contents stored in the storage unit 18 and controls the humidification amount of the humidifier 15 based on the contents.

In this case, the set value of the humidification amount stored in the second storage area 18b of the storage unit 18 is 0 (when the humidification amount is set to the median value of 0 on the screen of the humidification amount setting mode). ), The control unit 19 stores the set value in the storage unit 1
Then, the humidifier 15 is determined to indicate the standard humidification amount stored in advance in the third storage area 18c, and the humidifier 15 is controlled so that the humidified air corresponding to the standard humidification amount is supplied to the inside a of the refrigerator. Thereby, the inside humidity is adjusted so as to be a preset humidity. Therefore, for example, when it is desired to keep the inside a in the state of the nominal optimum storage humidity, the inside humidity may be set to the nominal optimum storage humidity, and the humidification amount may be set to zero in the humidification amount setting mode.

On the other hand, the second storage area 18a of the storage section 18
When the set value of the humidification amount stored in the humidification amount is not 0, that is, the humidification amount is set to + side or-
If the value is set to any value on the
No. 9 determines that the set value does not indicate the standard humidification amount. Then, whether the humidification amount supplied from the humidifier 15 to the inside of the storage a is larger than the standard humidification amount by a predetermined amount predetermined according to the set value (when the humidification amount is set to the + side), Alternatively, the humidifier 15 is controlled so as to decrease the amount (when the humidification amount is set to the negative side). As a result, the inside humidity is smaller than the set value stored in the first storage area 18a of the storage unit 18, that is, the apparent inside humidity set value displayed on the screen in the inside humidity setting mode. It is adjusted to be higher or lower by a predetermined amount.

[0031]

As described above, according to the present invention, both the setting of the humidity in the refrigerator and the setting of the humidification amount can be performed only by switching to the predetermined mode and inputting each set value. The work of adjusting the humidification amount can be performed easily as compared with the conventional deconditioner. Further, by simply changing the setting of the humidification amount, the humidity in the refrigerator can be substantially corrected or finely adjusted within a predetermined range without apparently changing the set value. That is, even if the set value of the humidity in the refrigerator displayed on the screen is not changed, the humidity in the refrigerator is substantially changed so that the desired humidity in the refrigerator can be obtained only by changing the set value of the humidification amount. Can be fine-tuned. Therefore, for example, even when a person who is not very familiar with the operation of the deconditioner finely adjusts the humidity in the refrigerator,
Since it is not necessary to change the set value of the in-compartment humidity displayed on the screen, it is also possible to eliminate anxiety that is remembered when changing the set value of the in-compartment humidity.
