Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a control device for a bread making machine that automatically controls the steps necessary for bread making such as kneading, fermentation and baking.

Conventional technology Traditionally, bread making involves kneading, fermentation, and 9 fermentation steps.

A firing process was required. Bread making machines that automatically control each of these steps to make bread have also been put into practical use. The configuration of this general bread making machine will be explained with reference to FIG. That is, a rotary blade 2 for kneading the bread ingredients is provided at the inner bottom of a container 1 containing bread ingredients such as flour and water, and this rotor blade 2 is driven by a motor 3. Also, container 1
Yeast 7 is heated by a heater 4 which is a heating means, and is charged into the container 1 from a yeast charging device 6 which is driven to open and close by a renoid 6. A signal from the thermistor 8 that detects the temperature inside the container 1 is input to an A/D converter 9, converted into a digital signal, and then input to a microcomputer 10 that controls each process. Furthermore, the microcomputer 10 controls the ON/OFF state of the switching elements 11 to 13, controls the energization of the heater 4 via the contacts 14a of the relay 14, and controls the energization of the heater 4 through the contacts 15a and 1es of the relay 16.
energization control of the motor 3 and furthermore, energization control of the solenoid 6 was performed via b.

Next, the control of the microcomputer 1o is shown in FIG.
This will be explained using a). First, the microcomputer drives the motor 3 to knead the bread ingredients in the container 1 in the kneading process. After mixing for a predetermined time, the solenoid 6 is driven to operate the yeast charging device 6, and the yeast 7 is charged into the container. After adding this yeast and kneading for a specified time,
Move on to the primary fermentation process. In this step, the microcomputer 10 controls the power supply to the heater 4 based on the signal from the thermistor 8, and controls the temperature inside the container 1 to a temperature T (approximately 28° C.) suitable for fermentation. After a predetermined period of time has elapsed, the rotary blade 2 is driven by the motor 3 to remove gas.

After performing secondary fermentation, degassing, and tertiary fermentation in the same manner, the set temperature is set from T1 to T2 (T2>T1), and shaping fermentation is started. When this shaping fermentation is completed, a baking process is started in which the heater 4 is energized to a temperature T3 suitable for bread baking, and the bread is baked.

Problems to be Solved by the Invention However, in conventional bread making machines, fermentation takes a long time, and it takes about 4 hours to bake bread.

As a result, there is a long wait time before eating freshly baked bread, and it is necessary to put bread ingredients into the bread maker and start operation well before the time to eat the bread. This had the problem of not being able to make it in time to eat.

In view of the above problems, the present invention shortens the time until the bread is baked, reduces the waiting time until the bread is baked, and provides a shortened course that can sufficiently cope with the case where the start of operation is delayed. It is an object of the present invention to provide a control device for a bread making machine which allows a user to select and use a shortened course and a regular course according to his/her wishes.

Means for Solving the Problems In order to achieve the above object, the control device for a bread making machine of the present invention includes a rotary vane driving means for driving a rotary vane that stirs the contents of a container containing bread ingredients; A heating driving means for driving a heating means for heating the container, a temperature detecting means for detecting the temperature inside the container, a first reference temperature signal generating means for generating a reference temperature signal of a normal fermentation temperature, and a first reference temperature signal generating means for generating a reference temperature signal of a normal fermentation temperature. a second reference temperature signal generating means for generating a reference temperature signal higher than the fermentation temperature; and an output of the temperature detecting means and the first reference temperature signal.
Alternatively, a comparison means for comparing the output of the second reference concentration signal generation means, and kneading and fermentation.

and a process storage means that stores the contents of each process such as baking, and the process storage means controls the rotary blade drive means and the heating drive means to control the process, and in the fermentation process, the comparison means The heating driving means is manually controlled by the output of the fermentation device, and is configured to be able to select whether to perform heating control at a normal fermentation temperature or at a temperature higher than the normal fermentation temperature.

Effect According to the above configuration, the fermentation process can be controlled at a temperature higher than the normal fermentation temperature, so the time required for the bread dough to rise to a predetermined size through fermentation can be reduced. As a result, the fermentation process time can be significantly shortened, and the total time required to bake the bread can also be significantly shortened. In addition, in the above configuration, it is possible to select whether to perform heating control at the normal fermentation temperature or at a temperature higher than the normal fermentation temperature, so the shortened course can be selected according to the user's wishes. and the regular course can be selected and used at will.

EXAMPLES Hereinafter, examples of the present invention will be explained based on FIGS. 1 to 3.

As shown in FIG. 1, the configuration of the control device of the bread making machine in this embodiment includes a rotary blade 2 for stirring the contents of a container 1 containing bread ingredients, a heater 4 for heating the container 1, and a heater 4 for heating the container 1.
These rotary blades 2 and heaters 4 are connected to rotary blade drive means 16. It is driven by heater drive means 17. Also,
A temperature detection means 18 such as a thermistor that detects the temperature inside the container 1, and a first temperature detection means 18 that generates a reference temperature signal of the normal fermentation temperature.
The output from the reference temperature signal generating means 19a is the comparing means 2o.
has been entered. Further, the output of the second reference temperature signal generating means 19b, which generates a reference temperature signal higher than the normal fermentation temperature, is also input to the comparing means 2o. The comparison means 20 then outputs the difference between the actual temperature inside the container 1 and the reference temperature to the process storage means 21. This process storage means 21 is composed of a microcomputer, and inputs a signal from a timer means 22 that generates a reference time signal for measuring the passage of time, and performs kneading, fermentation, and baking based on this signal. Controls the time of each process. Process storage means 2o
stores the control details of each process, and controls the rotary blade drive means 1e and the heater drive means 17 based on this content.

Next, the control of the shortened course in the process storage means 21 will be explained with reference to FIG. 2 and FIG. 3(b).

That is, when the operation is started, the rotary blade driving means 16 is turned on to perform a kneading process of kneading the contents of the container 1. When time t1 has elapsed, the yeast charging device is operated to charge yeast into the container 1, and the heater driving means 4 is turned on to continue kneading while warming the inside of the container 1.

When time t2 has elapsed, the rotary/motor stage 16 is turned off, the kneading process is completed, and the process proceeds to the primary fermentation process. In this case, the signal from the temperature detection means 18 and the normal fermentation temperature in the normal course shown in FIG.
The comparing means 20 compares the signal of the set temperature T4 (approximately 33.5° C.) of the second reference temperature signal generating means 19b, which is set higher than the temperature T4 (about 33.5° C.), and adjusts the temperature inside the container 1 to T4. The heater drive means 17 is controlled accordingly. After t3 hours have elapsed, the rotary blade drive means 16 is turned on to remove gas. Thereafter, a secondary fermentation process is performed while controlling the temperature inside the container 1 to T4. After t4 hours have passed, vent the gas again,
Further, the temperature inside the container 1 is controlled to T4, and the process of shaping fermentation is started. Then, when the time t6 has elapsed, the process moves to a baking process in which the heater driving means 17 is controlled to the baking set temperature T6, and after 16 hours, the baking is completed.

As mentioned above, the fermentation temperature is set to T1, the fermentation temperature of the normal course.
By setting the higher temperature T4, the dough made of bread ingredients will reach the desired size by fermentation faster, and therefore the total fermentation time for primary, secondary and shaping fermentation will be significantly reduced. You can bake bread in the same way as before. By shortening the fermentation time, the baking time for conventional bread, which required 4 hours, can be shortened to 2 hours and 46 minutes in this embodiment. In addition, the number of degassing operations was previously 3 times, but 2 times.
Since fermentation is carried out only once, it is possible to further shorten the fermentation time.

In addition, when the user selects the normal course, when moving to the primary fermentation step, the signal from the temperature detection means 18 and the fermentation temperature set to the normal fermentation temperature in the normal course shown in FIG. 3(a) are detected. The comparing means 2o compares the signal of the set temperature T1 (approximately 28° C.) of the reference temperature signal generating means 19a of No. 1,
Heater driving means 17 so that the temperature inside the container 1 becomes T1.
control. As a result, the normal course control shown in FIG. 3(,) is performed.

As described above, in the embodiment of the present invention, the user can select between the shortened course and the regular course according to his/her wishes, but in the case of the shortened course, the flavor of the bread is generally better than that of the regular course. However, even if the user desires such bread, in the embodiment of the present invention, bread with different tastes and textures can be made according to the user's preference. can be easily obtained.

In the above embodiments, a heater is used as the heating means, but a heating source based on combustion of gas or the like, a heating source using high frequency waves, or the like may also be used.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
Since it is configured so that it is possible to select whether to perform heating control at the normal fermentation temperature or at a temperature higher than the normal fermentation temperature, the user can select between the shortened course and the normal course depending on the user's wishes. can be done arbitrarily. In this case, if you select the shortened course, the fermentation process will be controlled at a higher temperature than the normal course, so the time it takes for the dough to rise to the desired size by fermentation will be shorter. Moreover, since the fermentation time is a large proportion of the total time required to bake bread, the total time can be significantly shortened.As a result, it is very useful when you want to make bread in a hurry, and it also depends on the user's preference. Bread with different tastes and textures can be easily obtained depending on the type of bread.
