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.

(Prior Art) In general, bread making at home can only be achieved successfully by using a kneading machine, a fermenter, a rolling pin, an oven, etc., and by skillfully managing difficult temperature and time. In order to automate this bread-making work, which requires skill, electrically like a rice cooker,
Conventionally, an electric bread maker 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 baking chamber 6, and belts 9, 10,
The kneading blades 7 are rotated at a reduced speed via 11. Also,
A lid body 13 having an inner lid 12 is formed in the baking chamber 6 so as to be openable and closable, and a water supply device 14 for supplying the kneading container 8 is further provided.

Reference numeral 15 denotes a temperature detection section for detecting the temperature of the kneading container 8, and reference numeral 16 denotes a control device for controlling the motor 3, heater 4, water supply device 14, etc., and the control conditions are set from an input device (not shown).

In the conventional bread making machine configured in this way, when the bread ingredients except water are put into the kneading container 8 and the desired baking time and control conditions are inputted 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 is stopped and the fermentation process begins. In the fermentation process, the temperature is controlled by the heater 4 according to the temperature of the kneading container 8, and the degassing process by the rotation of the motor 3 is repeated to advance the fermentation, and after a predetermined period of time, the heater 4 is energized. The baking process begins, and bread making is completed after a predetermined period of time.

(Problems to be Solved by the Invention) In such a conventional bread making machine, in order to bake at a desired time, the ingredients are placed in the kneading container 8 from the time the ingredients are put into the kneading container 8 until the bread making actually begins. Therefore, for example, if you set the baking time to bake the next morning and supply water to the ingredients the night before, yeast fermentation will begin before the kneading process begins, and the baking process will begin. becomes completely impossible. For this reason, a separate water supply device 14 is provided to supply water at the same time as the kneading process begins, but this requires a large water tank and a water supply drive device, which inevitably increases the size of the entire bread making machine. It is becoming. 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 is high, which increases the activity of the yeast 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.
It was necessary to take measures such as creating an insulated structure for the engine and adopting a cooling system in the summer.

In addition, if you start the kneading process with yeast added, the temperature of the dough will rise at the same time as fermentation starts, so if you do not adjust the kneading process time according to the temperature at the beginning of kneading the dough, The temperature of the bread dough may rise too high or become too low, and there is a risk that bread making will fail. Conversely, if you control the kneading start time so that the dough temperature is the optimum temperature, the fermentation time will change each time, which may result in over-fermentation or under-fermentation, resulting in bread-making failures. It was hot.

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 objects in an electric bread maker,
The solution is to have a kneading process at least twice before adding the yeast, and a standing process between each kneading process, and further to adjust the temperature of the bread baking mold to a predetermined temperature at least for a certain period of time before the final kneading. This problem is solved by a configuration that includes a control mechanism to

(Function) With the above configuration, the present invention kneads 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 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, 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 a kneading blade 30 which is rotated by a blade shaft 29 inside. Reference numeral 32 denotes a bread baking mold stand which pivotally supports the large pulley 25, pulley shaft 26 and lower connector 33, and at the same time, detachably fits and supports the upper connector 34 at the bottom of the bread baking mold 31. Further, a temperature sensing portion 35 is elastically pressed against the inner wall of the firing chamber 27 .

Furthermore, an inner lid 36 is provided on the inner surface of the upper part of the firing chamber 27.
A lid body 37 that elastically supports is formed to be openable and closable. When the lid body 37 is closed, the lower surface of the inner lid 36 comes into contact with the upper surface of the firing chamber 27, and the firing chamber 27 is closed. Completely sealed.

Furthermore, a yeast container 38 having an opening at the bottom for storing yeast is provided in the lid 37 above the bread baking mold 31, and is opened and closed by an actuator 40.

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.
8. This is performed by driving the actuator 40 and the like.
Note that 41 is a back plate, and 42 is leg rubber.

In the electric bread making machine of the present invention constructed as described above, first, a bread baking mold 31 equipped with a kneading blade 30 and filled with bread making ingredients such as flour and water excluding yeast is set 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 of the bread from a switch panel (not shown) in this state.
The leaving time of the bread ingredients is determined according to the set baking time, and when the predetermined time comes, the motor 22 is driven to the lower connector 33 via the drive system of the small pulley 23, belt 24, and large pulley 25.
is rotated, 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 via the blade shaft 29.

After that, kneading is performed several times as necessary.
During the final kneading, the actuator 40 drives the opening/closing plate 39 to open it, and the yeast is dropped from the yeast container 38 into the bread baking mold 31, and the bread ingredients and yeast are kneaded. Based on the input information from the temperature detection unit 35, each process such as primary fermentation, degassing, forming fermentation, and baking is automatically controlled based on the process control of the control device to determine the temperature of the bread dough at the set time. The bread is baked.

FIG. 2 is a diagram showing each of the above steps, with the horizontal axis representing time and the vertical axis representing 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 when yeast is added.

In other words, in the same figure, for example, when the room temperature is at the level of the broken line a, kneading b, c, etc. is performed several times during the standing time of the bread dough, and at the time of kneading, the bread dough has a certain temperature rise d, e, etc. However, once the kneading is completed, the temperature will gradually drop to room temperature a. Therefore, the present invention is designed to reduce the final kneading f when the room temperature is low.
By controlling the temperature of the bread dough for a certain period of time t before kneading, the dough at the time of final kneading f is adjusted to an optimal kneading temperature that prevents over-kneading or under-kneading. The subsequent bread-making process can also be controlled within a fixed time period, resulting in bread of stable quality and good quality. Note that, of course, if the room temperature is sufficiently high, the temperature control mechanism will not operate during the temperature control, 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.

(Effects of the Invention) As is clear from the above detailed explanation, the present invention kneads the bread dough at least twice during the standing time of the bread dough (including ingredients) determined by the set baking time. By adding yeast during the final kneading process and controlling the temperature of the bread dough from a certain period of time before the final kneading process, the temperature of the bread dough can be adjusted to ensure a sufficient temperature throughout the summer and winter without having to consider the activity of the yeast. Can be kneaded,
The final kneading time after adding yeast can be shortened, keeping the temperature of the dough low in the summer, and in the winter, by controlling the dough temperature before the final kneading, optimal kneading is possible even in a short time, so the temperature remains constant. The kneading time and temperature of the kneading process can be ensured, and the time and temperature control for subsequent processes can be kept constant, making it possible to maintain good baked quality throughout the year.
