Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to yakisoba, fried rice,
It relates to a vertical-type food stirrer that is useful for cooking vegetables and stir-fried foods, and it evenly loosens and stirs the food itself.
In addition, it was devised so that it could be fried and cooked with good heat efficiency in a short time.

[0002]

2. Description of the Related Art As a commercial stirrer used for stir-fry cooking of this kind of foodstuff, a horizontal rotary drum type reminiscent of a clothes dryer is generally used, and its typical example is a utility model. It is disclosed in Registration No. 3040706.

In the structure of this known device, a comb-shaped partition plate (9) from which a large number of round bars (9b) protrude is attached and fixed to a part of the inner peripheral surface of the horizontal rotary drum (1), and lifted by this. The foodstuffs (soba and cooked rice) (13) to be moved are naturally dropped in an inverted shape as the rotation of the rotary drum (1) progresses, and the rotation of the rotary drum (1) is performed immediately after the foodstuffs (13) are dropped. The food (13) is temporarily stopped for only a second, and the food (13) is heated during the intermittent stop.

[0004]

However, the partition plate (9) of the above-mentioned known device is integrally attached to the horizontal rotary drum (1) and does not perform its own motion separate from the rotary drum (1). Therefore, when the food material (13) is noodles, the comb-shaped partition plate (9) remains entwined with 360
There is a risk that they will be accompanied.

On the other hand, when the food material (13) is cooked rice, it cannot be reliably lifted up to the 10 o'clock position of the clock hands, and only the limited lower position up to that point can be slid back and forth, thus being inverted. hard. In particular, such a phenomenon becomes more prominent due to the fact that the food (13) is accompanied by oil and water and the traits are changed by heating.

[0006] Even if the foodstuff (13) can naturally fall in a reverse shape as the rotation of the rotary drum (1) progresses,
The partition plate (9) for that purpose works only in a limited part (for an angular range of about 30 degrees) at a predetermined position from 10 o'clock to 11 o'clock of the clock hand, let alone along the thrust direction of the rotary drum (1). Since the foodstuff (13) cannot be expected to move, it is impossible to efficiently and uniformly loosen and stir the whole foodstuff (13).

[0007] In stir-frying work using a wok, it is the same as when the cook does not use a so-called ladle, but shakes the pan itself to invert the ingredients, without loosening or stirring. Only the surface of the food that remains as a partial nodule is heated.

[0008] As a result of not being heated to the inside, the foodstuffs do not evaporate water and oil sufficiently, and it is finished as a stir-fried cooked product. To prevent this, if the heating temperature is raised, the surface of the foodstuff will be charred. Occurs.

Also, in the case of the above-mentioned known device, the horizontal rotary drum (1) is stopped for a few seconds each time when the clock hands that the foodstuff (13) is inverted and dropped reach from 10 o'clock to 11 o'clock, Since the heating is repeated during the temporary stop, it is not only complicated to control the intermittent stop and heating during that time, but it is also true that it corresponds to the kind of food (13) and the traits. It's impossible.

Further, while the horizontal rotary drum (1) is rotated around the horizontal axis, the gas burner (8) is fixedly installed and faces a part of the circumferential surface of the rotary drum (1) from below. Therefore, the heating part of the rotating drum (1) that is temporarily stopped, the food (13) at the next moment.
It will rotate to a position where there is no. In other words, it means heating many unnecessary points as a whole,
Its thermal efficiency is also very poor.

Further, since the rotary drum (1) is a horizontal type, the opening (1b) is laterally oriented and has a narrow opening area narrowed by the taper portion (1a).
Moisture and oil evaporated from the food material (13) during heating are not released quickly and smoothly, and the inside of the rotating drum (1) serves as a steamer for the food material (13). In that sense as well, the result is that the stir-fried cooked product is finished in a sticky state with residual oil and water.

Further, the lateral opening area of the horizontal rotary drum (1) is small, and moreover, a comb-shaped partition plate (9) provided with a large number of protruding round bars (9b) on a part of its inner peripheral surface.
Since it is fixed and integrated, it is very difficult to take out the stir-fry cooked food from the inside of the rotary drum (1), and then to completely clean the inside of the rotary drum (1). It is also less convenient.

[0013]

The present invention intends to radically solve these problems, and as a vertical food stirrer useful for this purpose, a top-opening type supported on a mounting table is used. Of the foodstuff storage pan, a horizontal rotation drive mechanism for rotating the foodstuff storage pan around a vertical center line, a heater for heating the foodstuff storage pan during horizontal rotation from below, and the inside of the foodstuff storage pan Equipped with a drive mechanism to loosen and stir the ingredients that are put into

A pair of left and right loosening / stirring arms forming the loosening / stirring arm drive mechanism are inserted into the above-mentioned food container from above so that the middle portions of both loosening / stirring arms are in opposite directions. The eccentric position of the rotationally driven rotating disk is pivotally connected to the eccentric position by a revolving spindle having a difference in length so as to maintain a constant front-rear distance, and the upper ends of both loosening / stirring arms are also pivotally connected so that they can be opened and closed. By doing so, both of the loosening / stirring arms are moved inside the foodstuff storage pan so as to draw an almost symmetrical elliptical locus.

After withdrawing and evacuating, the storage box (3) of the horizontal rotation drive mechanism (B) for the ingredient storage pan is tumbled by the tumbling actuation cylinder (7) of the tumbling actuation mechanism (C), and the above is carried by this. It suffices to keep the food container (A) in a front-down inclined posture as shown by the chain line in the figure. In the same manner, it is possible to easily and conveniently clean every corner of the food storage pan (A) after the stir-fried cooked product is taken out, which is also useful for its workability.

In that case, in the illustrated embodiment, the food is loosened.
The stirrer arm drive mechanism storage box (40) is entirely lifted by the lift actuating cylinder (45) of the lift actuating mechanism (F), and both loosening / stirring arms (60a) are lifted.
(60b) is designed to be pulled out and retracted from the inside of the food container (A), but instead of installing such a lifting operation mechanism (F), both loosening and stirring arms (60a) are installed. (60b) Hand for picking up food (66
a) A core rod (62a) integrally attached with (66b)
(62b) is slidably and slidably inserted into the sheath tubes (61a) and (61b), both are assembled and fixed to a certain length by a knock pin (not shown), and the core pin ( 62a) (62b)
May be shortened so as to be stored inside the sheath pipes (61a) (61b), and may be set to retract upward from the inside of the foodstuff storage pan (A). Then, the storage pan (A)
This is because the stir-fry cooked food can be easily taken out and the above cleaning work can be carried out conveniently and completely.

It is to be noted that a tipping for foodstuff storage pan (A) including the bearing boxes (2a) and (2b), the pivots (4a) and (4b), the pivoting arm (6), and the tipping cylinder (7).
