Description

[Detailed explanation of the invention] <Technical field of the invention> This invention relates to an automatic bread maker that can easily make bread at home, and is particularly designed to make bread that always tastes good whether it is winter or summer. The purpose of this invention is to provide an automatic bread making machine with

<Technical background of the invention> To bake bread, the ingredients such as flour, yeast, a small amount of butter, and sugar are kneaded together with water and subjected to primary fermentation, and after degassing, secondary fermentation is performed.
After degassing and forming and fermenting, it is finished by baking.

It is said that the most important factor that affects the taste of finished bread is the process of making the dough. In other words, the ideal method for making bread dough is to knead the dough for about 15 to 16 minutes until the temperature of the ingredients reaches around 27°C, and then finish the kneading process in this state to obtain the ideal bread dough. In order for the temperature of the dough to be around 27°C after kneading for about 15 to 16 minutes, it is desirable to keep the initial temperature of the ingredients at a constant temperature of, for example, around 15°C, regardless of summer or winter.

One way to keep the temperature of the ingredients at a constant level at the beginning of kneading is to cool the water that is added to the ingredients, using ice, for example, to 4-5℃, and then use this cold water to mix flour, yeast, butter, sugar, etc. By adding it to a material consisting of , it is possible to maintain a certain temperature range.

However, in winter, the ambient temperature can be 10°C or lower, and in summer, the ambient temperature can be around 30°C, so there is a large difference in ambient temperature. For this reason, when water cooled to 4-5℃ is added to the ingredients, there will be a slight difference in the temperature of the ingredients in winter and summer, and this temperature difference will cause a difference in the time it takes for the dough to reach about 27℃. arise. Therefore, the kneading time tends to be shorter in summer than in winter, which has the disadvantage that the quality of the bread tends to be worse in summer than in winter.

For these reasons, it is difficult to consistently make delicious bread using an automatic bread maker.

<Purpose of the invention> The purpose of this invention is to provide an automatic bread maker that can always make delicious bread no matter what the ambient temperature is.

<Summary of the invention> In this invention, the temperature inside the bread maker is controlled so that the ambient temperature when making bread dough is always a constant temperature of, for example, 15℃, and thereby the temperature of the ingredients at the beginning of kneading is always constant. The temperature of the bread dough is adjusted so that the time it takes for the dough to reach the optimum temperature of 27°C is constant, so that delicious bread can be made at any time.

<Example of the invention> An example of the invention is shown in the figure. In the figure, numeral 11 indicates a case that covers the entire bread making machine. Inside the case 11 are a material container 12, a water tank 13, a controller 14,
It houses the temperature control means 15.

The material container 12 has an upper lid 12a, and this upper lid 1
2a, the upper half of the case 11 is used as an opening/closing lid 11a, and when opening/closing lid 11a is opened, the upper lid 12a is opened.
By removing the container, ingredients such as flour, butter, yeast, and sugar can be added to the ingredient container 12.

A recess is formed in the upper lid 12a of the material container 12,
A small hole 12b is formed in this recess, and this small hole 12b
The structure is such that water can be injected from the water tank 13 through the tank. That is, a valve 16 is attached to the water tank 13, and a pipe 17 is connected through the valve 16. For example, an electromagnetic plunger 18 is attached to the valve 16,
The plunger 1 is activated by a command signal from the controller 14.
6 is activated, and water is injected from the water tank 13 into the material container 12 at a desired time. In other words, bread production generally takes about 3 to 4 hours because fermentation takes time.
For this reason, in order for the bread to be ready by 7 a.m., the operation must begin around 3 or 4 a.m. This control is performed by the controller 14, and when the finishing time is specified, the operation start time is automatically calculated, and at this time, the plunger 18 is controlled and water is injected into the material container 12.

A rotary blade 19 is provided on the bottom surface of the material container 12, and the rotary blade 19 is rotated by a motor 21 to knead the material into which water has been injected within the material container 12. 22 indicates a fixed blade, and this fixed blade 22 and the rotating blade 1
9 shows a case in which a kneader is constructed in which the material can be kneaded efficiently even when the rotational speed of the rotary blade 19 is lowered, and no noise is generated. A heat sensitive element 23 is attached to the axis of the rotating blade 19, and the temperature of the bread dough is measured by this heat sensitive element 23.

Reference numerals 24 and 25 indicate heaters disposed above and below the material container 12, and these heaters 24 and 25 heat the material container 12 to, for example, about 180° C. to 200° C. to bake bread.

In this invention, a temperature control means 15 is provided inside the case 11. This temperature control means 1
5 can be composed of a refrigerator 26 and heaters 24 and 25. The refrigerator 26 includes a compressor 28 driven by a motor 27, a condenser 29 that cools and condenses the refrigerant compressed by the compressor 28, and an expansion valve 31 that expands the refrigerant condensed by the condenser 29. The evaporator 32 absorbs ambient temperature by passing the expanded refrigerant. The condenser 29 is attached to the outside of the case 11 and releases the heat absorbed within the case 11 to the outside.

<Operation of the invention> The controller 14 injects water from the water tank 13 into the material container 12 at a predetermined time and activates the rotating blades 19 to start the kneading operation. Before starting this kneading operation, the controller 14 measures the temperature inside the case 11, and if the temperature inside the case 11 is higher than 15°C, it operates the refrigerator 26 to absorb the heat inside the case 11 and create a condenser. 2
Heat is released from 9 to the outside, and the temperature inside case 11 is increased.
Control to maintain around 15℃.

On the other hand, the temperature inside case 11 is 15 as in winter.
℃ or below, a preheating current is applied to the heaters 24 and 25 to heat the heaters 24 and 25, and the case 1
Control the temperature inside 1 to around 15℃. This temperature control operation is performed by adding bread ingredients to the material container 12 the day before.
The temperature control means 15 may be started from the time when the temperature control means 15 is set to 1, or the temperature control means 15 may be started several hours before the kneading operation for obtaining bread dough is started. The point is that the temperature of all ingredients, including water, should be around the predetermined 15°C at the beginning of kneading. Further, the temperature control may be stopped either at the start of kneading or at the end of kneading.

<Effect of the invention> As mentioned above, according to this invention, the temperature inside the case 11 of the automatic bread maker can be adjusted at any time regardless of the season.
Since it operates to maintain a constant temperature of about 15°C, the conditions for kneading bread dough can always be close to ideal. Therefore, it is possible to provide an automatic bread maker that can always make delicious bread.

<Modified embodiment of the invention> In the above, when the temperature inside the case 11 is lower than 15°C, a preheating current is applied to the heaters 24 and 25, and the case 1 is heated.
1 is configured to maintain the temperature inside the case 11 at 15°C, the refrigerator 26 is reversed and the evaporator 32 inside the case 11 is operated as a condenser to absorb heat from the outside air. It can also be configured to heat.
