Abstract

PURPOSE: To bring a dough under collision condition to the side wall to make the whole dough hardly rotate and to perform eventually enough kneading by providing a kneading blade at a proper lengthwise position on the bottom part in a kneading container formed into a rectangular parallelepiped. CONSTITUTION: A kneading blade 16 with approximately the same size as the narrow side width of a kneading container 15 is provided at the center or at a lengthwise eccentric position from the center on the bottom part in a kneading container 15 formed into a rectangular parallelepiped with a rectangular plane. When a motor 4b is driven, the kneading container 15 is not rotated but only the kneading blade 16 is rotated to perform kneading motion of the content in the kneading container 15. When a dough is put into the kneading container 15 and the kneading blade 16 is rotated, as there exists room for a space in the lengthwise direction of the kneading coontainer 15, the dough tends to extend to a lengthwise wide space side and even if it tries to be rotated, a condition where this collides with the side wall is kept and it hardly rotates as the whole, and kneading inside is mainly performed and the whole kneading is eventually enough performed.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an apparatus for kneading bread dough and the like.

(Conventional technology) When making delicious bread, temperature control and time control are important in each process, but for example, the kneading process of kneading bread mix such as strong flour, sugar, and salt with water and dry yeast is also extremely important. is important.

Conventionally, the first kneading device used in this kneading process was
As shown in FIG.
It is known that the dough is rotated at rotational speeds of 00r, p, and m to knead the dough placed in the kneading container a.

(Problems to be Solved by the Invention) However, the conventional apparatus described above has the disadvantage that sufficient kneading is not necessarily performed.

This inconvenience occurs because as the kneading progresses, gluten is formed, which increases the viscosity and adheres to the kneading blades and becomes a single piece, forming a ball-like shape and rotating.

Therefore, it is conceivable to provide a convex part on the inner surface of the side wall of the kneading container a so that the dough hits this and acts as a resistance, preventing the dough from rotating as a unit when kneading the blades.
In particular, when the dough is kept in the kneading container a and the steps from kneading to baking are performed continuously, there is a problem that the appearance of the finished bread is deteriorated due to the influence of the protrusions.

(Means for Solving the Problems) The present invention aims to provide an apparatus that eliminates the above-mentioned disadvantages, and is intended to provide a device in which kneading blades are attached in the longitudinal direction at the bottom of a kneading container formed into a rectangular parallelepiped in plan view. It is characterized by being installed at the appropriate location.

(Function) When you put bread dough into a kneading container and rotate the kneading blades,
Since there is plenty of space in the length direction of the kneading container, the dough tends to stretch toward the wide space in the length direction, and even if you try to rotate it, it will collide with the side wall and the dough will not rotate as a whole. As a result, while internal kneading is mainly performed, overall kneading is sufficiently performed in the end.

(Example) Next, an example in which the apparatus for kneading bread dough or the like of the present invention is housed in a hot air oven equipped with a microwave oven will be described based on the drawings.

In Figures 1 to 3, (1) shows the main body of the cooking device, inside the main body (1) there is a door (2) at the front, a circulation fan 3) at the rear, and a turntable (4) at the bottom. )・The kneading blades of the kneading container a@ (1! i + heating chamber (5) equipped with a drive shaft (4a) for driving, and the gas burner 0 which is the heat source (6) on the lower side of the heating chamber (5) Combustion chamber (7'

and is provided.

A turntable (4) driven by the drive shaft (4a)
) is mainly used in a high-frequency cooker using a high-frequency oscillator ω, and its drive shaft (4a) is connected to a transmission member (I
A constant speed motor (
4b).

As shown in FIG. 4, the drive shaft (4a) has an upper end formed into a cross-shaped support section when viewed from above, and the turntable (4) has an upwardly facing support section provided on each of the six pieces of the support section. It was designed to be supported by the convex portion (4a-1). In this case, the rotation speed of the turntable (4) is lor, p, 1st, so it is sufficient to support it only on the convex part (4a-1), but if there is a fear of slipping, the turntable (4) It is preferable to provide a recess into which the projection (4a-1) is inserted at the bottom.

The transmission member (IO) includes a pulley (10a) connected to the drive shaft (4a), a pulley (10b) connected to the rotating shaft of the motor (4b), and a belt (10a) suspended between both pulleys (10a) (10b). 10c) and both pulleys (10c).
a) (10b) is a two-speed transmission type.

The control device (8) operates in conjunction with the operation of the operator (11) provided above the door (2), and controls combustion of gas burner 0, ON-OFF control of high-frequency oscillator ■, and circulation fan (3). ) operation control of the motor (8a) of the turntable (

In the figure, a indicates a temperature sensor, for example, a thermistor, installed on the ceiling of the heating chamber (5), and (1
3 indicates a disk-shaped fixing means which is loosely fitted to the drive shaft (4a) and attached to the bottom wall of the heating chamber (5), and 11Φ indicates a kneading container (at the bottom of the IS) formed into a rectangular parallelepiped in plane. The kneading device is equipped with a kneading device in which a kneading blade CIe of approximately the same size as the narrow width of the kneading container (ISl) is provided in the center as shown in FIG. 5, or eccentrically provided in the length direction from the center as shown in FIG. show.

According to the above-mentioned configuration, during normal cooking, when the operator a1 is operated to ignite the gas burner 0 and operate the circulation fan (3), the combustion chamber (7) is circulated in the heating chamber (5). The heat from the turntable (4)
) is heated and cooked. At this time, the gas burner 0 is controlled by the temperature sensor (+21) via the control device (8) to maintain the temperature inside the heating chamber (5) at the set temperature.

Moreover, if the high frequency oscillator (2) is activated, high frequency cooking will be performed, and if the gas burner 0 and the high frequency oscillator (2) are activated simultaneously, so-called complex cooking will be performed. In these cooking cases, the turntable (4) rotates to improve the distribution of hot air and high frequency waves to the food to be cooked.

Next, the operation of kneading bread dough will be explained.

At this point, place the kneading container (IS kneading feathers) containing the dough.
As shown in FIG. 4, the lower end of the IG shaft (16a) is formed into a cross bar-shaped connecting portion (IGa-1) when viewed from below, and this connecting portion (16a-1) is connected to the drive shaft (4a). ) is engaged from the side to transmit rotation.

When kneading bread dough, the turntable (4) in the heating chamber (5) is removed from the drive shaft (4a), and the kneading container (+51) is placed in the heating chamber (5) instead.
Connect the connecting part (16a-1) of the QO axis (16a) to the drive shaft (4
Both shafts (16a) are engaged with the convex portion (4a-1) of a).
(4a), and the convex part (15a) of the bottom plate of the kneading container a9 is engaged with the concave part (13a) of the fixing means a3, and the kneading container (+5) is connected to the heating chamber via the fixing means (13). 5) and then operate the motor (4b), the kneading container (+5) is not rotated and the kneading blades a
Only O is rotated to knead the contents in the kneading container (ISl).

In this case, as mentioned in the section above, the dough tends to escape and stretch into the space in the length direction of the kneading container, and it remains in a state where it collides with the side wall for a period of time and is rotated. The dough is thoroughly kneaded.

In addition, the rotation speed of the turntable (4) is 10r, p, n+
The rotation speed of the kneading blade aG is 300 r, p, 11
Therefore, the rotation speed switching device (+7
1 is required. For example, as shown in FIG. 7, the rotation speed switching device (+71) is a lever (181) whose both sides swing up and down around a shaft (18a), and one end of which is connected to the high-frequency cooking activation button agl. When the button 119 is turned on, the rod (20a) is connected to the rod (20a) of the cylinder (20a), which moves up and down when the button 119 is turned on, and the other end is connected to the drive shaft (4a). (4a)
moves upward, and the pin (4a-2) at the top engages with the large diameter pulley (10a-1) on the low speed side, causing the turntable (4a-2) to move upward.
) is rotated at low speed (10r, p, l11), and when the button (+9) is turned off, the rod (20a) moves upward and the drive shaft (4a) moves downward, causing the lower bottle ( 4
Kneading blades when a-3) is engaged with the small diameter pulley (10a-2) on the high speed side and the kneading container (I!i) is accommodated in the heating chamber (5) instead of the turntable (4) A device that rotates ae at high speed (300r, Lll) is used.

According to the experiment conducted by the inventor of the present application, the state of kneading the dough by changing the dimensions of the kneading container (ISl) at a room temperature of 21°C revealed that the flat surface of the kneading container aD as shown in the table below and FIG. It was confirmed that the state of kneading improves when the shape is made rectangular.

At this time, when observing the case of ■ where the kneading blade aO is placed in the center and the case of ■ where the kneading blade aO is placed eccentrically, it is found that in the case of ■, spaces exist on both sides in the length direction, and the powder that is blown outward is also Although it exists on both sides, it exists in the form of a mass of powder that is kneaded by the kneading blade (IQ) and extends into the space on one side.

Therefore, in this case, when the lump-like material moves from one space to the other from time to time, the powder there will adhere and be kneaded, and eventually the entire amount of powder will be kneaded. On the other hand, in the case of ■, the space exists on one side in the length direction, so some of the powder is blown to the outer side wall of the space on one side by the kneading blade (IO), and a part of the powder is blown away by the kneading blade (IO) to the outer side wall of the space on one side. Most of the powder that is collected exists in clumps that extend into the space.

The powder that is blown outward gradually adheres to this lump-like material and becomes unified, and finally the entire amount of powder is kneaded. In this case, since the powder blown outwards is on one side, it adheres to the lump-like object more quickly than when there is space on both sides.
It will be kneaded.

In addition, the space in ■ is larger on both sides in the longitudinal direction,
The flour tends to be blown out and become too watery at the start, making it difficult to form clumps, so we devised a way to put the flour and water into the kneading container (ISl). If you put something on both sides of the flour, the wateriness at the start will disappear, and after it forms a lump, the flour that has flown to both sides will be able to stick to both sides. It is also good to apply.

In other words, one that is eccentric and has a space on one side has a 100% difference compared to one that is located in the center and has a space on both sides.
The size of the two spaces becomes larger, and the trend is similar to the one in ■. Therefore, in this case, the water is kneaded by the blade ae.
It is best to put it on the side where there is no space.

In addition, the one with ■ uses the kneading blade aO shown in Fig. 9B, and according to this, even when the axis of the kneading blade aO is arranged as the center, the kneading blade aO has a lump-like shape compared to the ones with ■ to ■. Since the powder moves from one space to the other space many times, the powder from the rain space that is blown toward the outer side wall of the space will adhere to clumps at an earlier stage and be kneaded.

As shown in Fig. 9C, the kneading blades aO are arranged so that the - side extends parallel to the bottom of the kneading container (15+) and the other side extends perpendicularly to the bottom of the kneading container I'15 while rotating. It was confirmed that the condition of kneading becomes worse when

This is thought to be because in the case where the kneading blade (IG) is shaped to stand up, the dough rises along the kneading blade 00 and rotates with the kneading blade aO as in the conventional type.

(Effects of the Invention) As described above, the present invention is characterized in that the kneading device is formed by providing kneading blades at appropriate positions in the longitudinal direction at the bottom of the kneading container formed into a rectangular parallelepiped in plan view, so that the dough can be made into a long dough. This tends to stretch into the space in the horizontal direction, which collides with the side wall and rotates the entire dough, causing internal kneading to take place mainly and eventually kneading to a sufficient extent, as described above. There is no need to provide a convex part on the inner surface of the side wall, and the appearance of the finished bread can be maintained even when the dough is kept in the kneading container and the kneading process to the baking process is performed continuously. has.
