Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic bread maker that can automatically bake bread simply by adding predetermined ingredients.

In the conventional automatic bread making machine, bread ingredients are kneaded and subjected to a long aging process as shown in Figure 4 (Ca) (B).

The process of adding yeast and kneading it again, fermenting it, degassing it, shaping fermentation, and baking it is done automatically, but conventionally when kneading bread dough, the temperature of the dough changes as it is kneaded. As it rises,
When the dough temperature reached approximately 28° C. or higher, this kneading operation was stopped to prevent the dough temperature from rising any further. This is because if the dough temperature rises too much during kneading, the bread will be unpalatable, so bread dough must be kneaded at at least 35°C or lower. but.

If the kneading operation is stopped midway due to temperature rise.

When the temperature is high, there is insufficient kneading time and less gluten is produced, which tends to result in sticky, dull, and tasteless bread.

Problems to be Solved by the Invention As described above, in the past, the kneading operation was stopped in order to prevent the dough temperature from rising, but this had the problem of insufficient kneading time.

The present invention solves this problem. Even after kneading is stopped once the temperature exceeds a certain level, kneading is performed for a while, and then kneading is performed again when the dough temperature drops to prevent insufficient kneading. The purpose of this invention is to provide an automatic bread maker that solves the problems.

Means for Solving the Problems In order to solve the above problems, the automatic bread maker of the present invention includes a baking chamber having a heater, a bread baking mold that can be detachably attached to the baking chamber, and an inner bottom part of the bread baking mold. a kneading device comprising a kneading blade provided in the kneading blade and a motor for driving the kneading blade; and a temperature detection means for detecting the temperature of the bread baking mold.

The temperature detection means detects that the temperature of the bread baking mold during pre-kneading has exceeded a certain temperature and stops the motor, and detects that the temperature of the bread baking mold has fallen below a certain temperature and restarts the motor. The heater is configured to include a control device that controls the heater and the motor so as to operate the motor and repeat this operation until the cumulative operating time of the motor reaches a predetermined time.

Effect: With the above configuration, even after the kneading has been stopped once the temperature exceeds a certain level, the kneading can continue for a while.

When the dough temperature drops, perform the kneading operation again.

To prevent insufficient kneading at high temperatures by extending the cumulative time of kneading time to a certain time or more, and to improve the finished product of bread.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

Figure 2 shows the entire automatic bread making machine used in the present invention,
Chassis 2 provided inside the main body 1 of the bread making machine
A motor 3 is fixed to the shaft of the motor 3, a small pulley 4 is fixed to the shaft of the motor 3, and power is transmitted to a large pulley 6 via a belt 5.

A heater 8 is provided in the baking chamber 7, and a bread baking mold 1 having a removable kneading blade 9 at the bottom is mounted on the heater 8.
0 is arranged, and the shaft 9a of this kneading blade 9 is fixed to the large pulley 6 and driven by the motor 3, and the kneading blade 9
and the motor 3 constitute a kneading device. An elastically supported temperature sensing portion 11 protrudes from the side surface of the baking chamber 7 and is pressed against the side surface of the bread baking mold 10 . The upper surface of the firing chamber 7 is sealed by a lid 12 that can be opened and closed and an inner lid 13 provided on the lower surface of the lid 12. 14
is a control device, and as shown in FIG.
The motor 3
and controls the heater 8. Reference numeral 16 denotes a yeast spout provided in the lid 12 for introducing yeast after the soaking process.

FIGS. 1(a) and 1(b) are process characteristic diagrams schematically showing changes in bread dough temperature and motor energization at each step in the automatic bread making machine of the present invention. The operation of the control bag Wi14 will be explained below with reference to FIG. first.

Start by adding ingredients other than yeast such as flour, water, butter, and sugar to bread baking mold 10.

Pre-kneading gradually increases the dough temperature.

If the temperature is low, pre-kneading is performed for 30 minutes, but if the temperature is about 25°C or higher, as shown in Figure 1 (a).

The dough temperature reaches 33° C. or higher within 30 minutes due to the pre-kneading, and at this time the motor 3 is stopped as shown in FIG. 1(b). When the motor 3 stops, the dough temperature gradually decreases, and when it becomes 33° C. or lower, the motor 3 starts the pre-kneading operation again. Repeat this operation until motor 3
When the cumulative operating time exceeds 40 minutes, the pre-kneading operation by the motor 3 is terminated and a boiling process for a certain period of time begins. After this resting time, yeast is added, and after kneading for about 15 minutes, fermentation begins. During this fermentation, degassing is performed three times as shown in Figure 1 (b). Firing begins approximately 50 minutes after the third degassing, and approximately 1
Bake at 50℃ for about 1 hour and the bread is ready.

In this example, a microcomputer was used to control the heater and motor and measure time.

Effects of the Invention As described above, the automatic bread maker of the present invention temporarily stops the pre-kneading operation when the temperature of the bread baking mold during pre-kneading reaches a certain temperature or higher, and resumes the pre-kneading operation when the temperature falls below the certain temperature again. By repeating the starting action, it is possible to secure sufficient time for pre-kneading without raising the temperature of the bread dough, and it is possible to make bread of good quality even when the room temperature is high.
