Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electric bread maker for home use that is capable of making bread on a timer similar to an electric rice cooker.

(Conventional technology) Generally, bread making at home involves two kneaders and two fermenters.

Success is achieved only through skillful and difficult control of temperature and time using a pan or oven.

In order to electrically automate this bread-making work, which requires skill, like a rice cooker, an electric bread-making machine for home use as shown in FIG. 3 has been proposed.

That is, FIG. 3 is a sectional view showing a conventional electric bread maker (hereinafter simply referred to as a bread maker), in which 1 is a main body case, which has a chassis 2 inside, a motor 3, a heater 4, and a A firing chamber 6 equipped with a heat insulating material 5 is fixed. A kneading container 8 having kneading blades 7 is detachably attached to the firing chamber 6, and belts 9.1 and 12 are driven by the motor 3.
The kneading blade 7 rotates at a deceleration speed of 0.11. Further, the baking chamber 6 is provided with a lid 13 having an inner part 12 that can be opened and closed, and is further provided with a water supply device 14 for supplying water to the kneading container 8.

15 is a temperature detection unit that detects the temperature of the kneading container 8;
16 is motor 3. This is a control device that controls the heater 4, water supply device 14, etc., and its control conditions are set from an input device (not shown).

In the conventional bread making machine configured in this way, when bread ingredients except water are put into the kneading container 8 and the desired baking time and control conditions are entered from the input device (not shown), the desired baking time and control conditions are input. At a predetermined time, the operation of the water supply device 14 and the motor 3 is started according to a timer, and the kneading process proceeds while the temperature of the kneading container 8 is detected by the temperature detection section 15 until it reaches a predetermined temperature or At a predetermined time, the motor 3 stops and the fermentation process begins.In the first fermentation process, the temperature is controlled by the heater 4 depending on the temperature of the kneading container 8, and the degassing process by the rotation of the motor 3 is repeated, and fermentation progresses. After a predetermined period of time has elapsed, the heater 4 is energized to begin the baking process, and after a predetermined period of time, bread making is completed.

(Means for solving the problem) In such a conventional bread making machine, in order to bake at a desired time, from the time the ingredients are put into the kneading container 8 until the bread making actually starts, the materials are kept in the kneading container 8. Therefore, for example, the night before, if you set the baking time to bake the next morning and supply water to the ingredients, the kneading process will start ^II, the yeast will begin to ferment, and the bread will be made. I can't do it at all. For this reason, a water supply device 14 is separately provided to supply water at the same time as the kneading process begins, but this requires a large water tank and water supply drive device, so the drawback is that the entire bread making machine is inevitably large. It has become. In addition, if a separate water supply device 14 is provided in this way, the water temperature increases in the summer, so the water supply temperature during the kneading process becomes high, which increases yeast activity too much, making it impossible to make satisfactory bread. In some cases, the activity of the yeast weakens, and in some cases, the yeast dies, making it impossible to make bread, or in extreme cases, the water dispenser 14 freezes. Therefore, countermeasures such as adopting a cooling configuration were necessary.

In addition, if you start the kneading process with yeast added, the temperature of the dough will rise at the same time as fermentation begins, so unless you adjust the kneading process time according to the temperature at the beginning of kneading the dough, the temperature of the dough will increase. The temperature may rise too high or become too low, which may result in bread making failure. Conversely, if you control the kneading start time so that the temperature of the dough is at the optimum humidity, the fermentation time will change each time, which can lead to over-fermentation or under-fermentation, resulting in bread-making failures. there were.

The present invention aims to solve the various problems mentioned above in electric bread making machines.

(Means for Solving the Problems) The present invention achieves the above-mentioned purpose of an electric bread maker by kneading the dough at least twice during the dough standing time set by inputting it from a human-powered device. This is solved by a configuration in which yeast is mixed into the bread dough from a yeast introduction device immediately before or during the kneading, and a control mechanism is provided to bring the temperature of the bread baking mold to a predetermined temperature at least for a certain period of time before the final kneading.

(Function) With the above configuration, the present invention kneads the bread dough at least twice during the required standing time, adds yeast at or during the final kneading, and Since the temperature of the bread dough is controlled and adjusted to a predetermined temperature from a certain period of time in advance, the temperature of the bread dough after adding yeast can always be kept at a constant temperature that is optimal for bread making, regardless of the season. Since the baking process can be kept constant during the bread making process, automatic baking of bread becomes possible easily, simply, and in a good manner.

(Example) Hereinafter, the present invention will be explained in detail with reference to Examples.

FIG. 1 is a sectional view showing an electric bread maker according to an embodiment of the present invention. In the figure, 20 is a main body case of the bread maker (hereinafter simply referred to as the main body), 21 is a chassis, and a motor 22 is fixed. A small pulley 23 is fixed to one end of the shaft, and its rotation is transmitted to a large pulley 25 via a belt 24 to rotate a pulley shaft 26. Reference numeral 27 denotes a bread baking chamber, which houses a bread baking mold 31 having a heater 28 fixed to its inner bottom and rotatably provided with kneading blades 30 which are rotated by a blade shaft 29 inside. 32 is a bread baking mold stand with the above-mentioned large boo IJ25. Pulley shaft 26 and lower connector 33
At the same time, an upper connector 34 at the bottom of the baking mold 31 is detachably fitted and supported. Further, a temperature sensing portion 35 is elastically pressed against the inner wall of the firing chamber 27 .

Furthermore, a lid 37 that elastically supports an inner lid 36 on its inner surface is formed in the upper part of the firing chamber 27 so as to be openable and closable.By closing this lid 37, the lower surface of the inner lid 36 is
It comes into contact with the periphery of the upper surface of the firing chamber 27 to completely seal the firing chamber 27.

Furthermore, in the part of the lid body 37 above the bread baking mold 31.

Yeast 1 - A yeast container 38 having an opening at the bottom for accommodating bacteria is provided, and the actuator 40 is used to open and close the yeast container 38.
driven by.

The baking time of the bread, etc. is controlled based on input from a switch panel (not shown) and input information from the temperature detection section 35, and the motor 22. Heater 28. Actuator 4
This is done by driving 0 etc. Note that 41 is a back plate, and 42 is leg rubber.

The electric bread maker of the present invention configured as described above has the following features:
A bread baking mold 31 is equipped with a kneading blade 30 and filled with bread making ingredients such as flour and water excluding yeast.

Set the bread in the baking chamber 27, close the lid 37, put a predetermined amount of yeast in the yeast container 38, and set the baking time for the bread from the switch panel (not shown). Depending on the time of day, the time the bread ingredients are left out is determined.

When the predetermined time comes, the motor 22 moves the small pulley 23. The lower connector 33 is rotated through the drive system of the belt 24 and the large pulley 25, and the upper connector 34 fitted thereto is driven, and the first kneading is performed by the kneading blades 30 in the bread baking mold 31 through the single blade shaft 29. will be held.

After that, kneading is performed several times as necessary, and during the final kneading, the actuator 40 drives the rIIc11 plate 39 to open it, and the yeast container 38 is transferred to the bread baking mold 3.
Drop the yeast into a bowl and knead the bread ingredients and yeast. Based on the input information from the temperature detection unit 35, the temperature of the bread dough is automatically controlled and set based on the process control of the control device. Bread is baked on time.

Figure 2 is a diagram showing each of the above steps, with the horizontal axis representing time.

The vertical axis represents the temperature of the dough. In this figure, the temperature of the bread dough is controlled to a predetermined temperature for a certain period of time before the final kneading, and the temperature of the bread dough is maintained optimally during the final kneading in which the yeast 1 to bacteria are introduced.

In other words, in the same figure, for example, when the room temperature is at the level indicated by the broken line a, kneading, c, etc., are performed several times during the time the bread dough is left to stand, and at the time of kneading, the bread dough experiences a certain temperature rise d, e, etc. However, once the kneading is completed, the temperature of the bread dough will gradually drop to the room temperature a. Therefore, the present invention is designed to control the temperature of the bread dough for a certain period of time t before the final kneading f when the room temperature is low. By this, the dough at the time of final kneading is adjusted to the optimum kneading temperature without the risk of over-kneading or under-kneading. The subsequent bread-making process can also be controlled within a fixed time period, resulting in the baking of good-quality bread with stable quality. Note that if the room temperature is 1 minute higher, the temperature control mechanism during temperature control will of course not operate, and the final kneading f will begin.

The present invention has been described in detail using one embodiment, and the present invention is particularly an automatically controlled bread making machine that kneads bread dough while automatically controlling the temperature.

(Effect of the invention) As will be clear from the detailed description below, the present invention is as follows.

During the standing time of the bread dough (including ingredients) determined by the set baking time, the bread dough is kneaded at least twice, and during the final kneading, Y-s I-m is added, and the final kneading is performed. By controlling the temperature adjustment of the bread dough from a certain time in advance, sufficient kneading is possible throughout summer and winter without considering yeast activity, and the final kneading time after yeast is added can be shortened.
In the summer, the temperature of the dough can be kept low, and in the winter, by controlling the temperature of the dough before final kneading, optimal kneading is possible even for a short time, ensuring a constant kneading time and temperature, and controlling the subsequent process. Time and temperature control can be kept constant, ensuring good baked quality throughout the year.
