Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a mixing device for a plurality of ingredients, for example, a rotating device for mixing a plurality of ingredients to prepare so-called mixed rice or sushi rice such as gomokumeshi.

[Conventional technology]

2. Description of the Related Art Conventionally, as a rotary mixing device for mixing two or more types of raw materials such as foods, the one disclosed in Japanese Patent Publication No. 62-57371 is known.

The rotary mixing device disclosed in this publication has a cylindrical rotating container that is elongated in the direction of the rotational axis, and has a raw material inlet and an outlet, and has a partition plate inside the rotating container that is obliquely perpendicular to the rotational axis. Due to the partition plate, two or more rotating raw materials are mixed homogeneously in a short time by adding movement in the axial direction to the movement in the circumferential direction. be.

[Problems to be Solved by the Invention] However, when the above-mentioned conventional rotary mixing device is used to prepare so-called mixed rice such as sushi rice and gomoku rice, it has the following problems. (1) Since a partition plate is used as a member for stirring the raw materials, the pressure on the raw materials tends to be strong, and it is unavoidable that, for example, a portion of cooked rice may be kneaded more than necessary.

(2) On the other hand, there was also the unavoidable inconvenience that some of the viscous cooked rice would stick to the partition plate and form a ball. The present invention was made in view of the above-mentioned problems of conventional devices, and includes a method for preparing viscous cooked rice and ingredients for mixed rice.
To provide a mixing device for a plurality of foodstuffs capable of uniformly mixing vinegar and the like in a short time.

[Action 1] First, by operating the operating handle, the rotating container is erected so that its opening faces directly upward.

In this state, remove the lid that is attached to the opening, put the cooked rice and vinegar, or ingredients for mixed rice, and other ingredients into the rotating container, and then attach the lid again. Seal the rotating container.

Then, by operating the operating handle again, the rotating container is horizontally hung so that its axis of rotation becomes horizontal. When the motor is driven to rotate the rotating container in this state, the cooked rice and vinegar or ingredients in the rotating container are uniformly mixed by the stirring member that rotates as the rotating container rotates.

In other words, as agitation members in the rotating container, multiple stirring bars arranged at predetermined intervals are built in parallel over two stages, so that they rise and fall as the rotating container rotates. The above-mentioned plurality of foodstuffs, which repeat this process repeatedly, collide with each stirring bar during the process and are crushed, thereby exhibiting an excellent stirring effect.

During this time, when the blower is activated and air is blown into the rotating container through the air pipe facing the air blowing and exhaust hole in the lid of the rotating container, the air circulates inside the rotating container and is exhausted to the outside through the air blowing and exhaust hole. .

By cooling the surface of the rice grains and forming a film in this way, delicious and glossy sushi rice and mixed rice can be obtained. [Example] Hereinafter, an example of the present invention will be described based on the drawings.

Reference numeral 1 denotes a cylindrical rotating container with an opening 1a at one end.

Reference numeral 2 denotes a support ring which is inserted approximately at the center of the outer periphery of the rotary container 1 with a slight gap, and a plurality of rollers 3 (four in the embodiment) are mounted on the front end surface of the support ring at equal intervals. supported,
The rotating container 1 is rotatably supported by the rollers 3.

Reference numeral 4 denotes a U-shaped frame fixed to both sides of the support ring 2, and horizontal support shafts 5 are provided protruding from the rear of the support ring 2 of the frame 4.

On the other hand, a drive box 6 for the rotary container 1 is fixedly installed on one side of the rear surface of the frame 4.

Reference numeral 7 denotes support columns installed on both sides of the upper surface of the base plate 9 with casters 8, and support shafts 5 protruding from both sides of the frame 4.
is rotatably supported above the support column 7.

A manual handle 10 is attached to the outer end of one (right side in the figure) of the support shaft 5, and by rotating the handle 10, the support ring 2 is supported via the roller 3. The rotational position of the rotating container l is adjusted by about 90 degrees.

That is, when stirring or taking out food a, the rotary container l is placed horizontally so that the axis of rotation is horizontal as shown in Figure 1, while when adding food a, the rotating container l is hung horizontally as shown in Figure 3. The rotating container l is placed upright so that the part 1a faces upward. Next, reference numeral 11 denotes a lid body that is attached to the opening 1a of the rotary container 1 in a sealed state, and a plurality of lids (
In the embodiment, four fastening fittings 12 are used to allow for removal, and a ventilation/exhaust hole 13 is opened in the center.

A taper 13a projecting outward is formed on the periphery of this ventilation/exhaust hole l3 to prevent the food material a from sticking out during stirring.

14 is a stirring member which is a main component of the present invention, and is removably housed in the cylindrical rotating container 1. That is, a plurality of (five in the example) stirring bars 14a
A pair of stirring members 14 are arranged in parallel at a predetermined interval so as to be substantially parallel to the rotation axis of the rotating container, and the front and rear ends of the stirring members 14 are connected by support bars 14b. The entire structure is assembled by inserting the bars 14b into an annular holder 14c in parallel with each other at a predetermined interval. Therefore, the outer diameter of the holder 14c is made to substantially match the inner diameter so that it fits in the rotating container 1, and
The length of the stirring bar 14a is made to substantially match the length of the rotating container 1 so that it touches the inner bottom of the rotating container 1, and the distance between the pair of stirring members 14 is set so that the inner wall of the stirring container 1 is in contact with the inner bottom of the rotating container 1, as shown in FIG. It is desirable to make all the intervals approximately equal. Further, the positional relationship between the pair of stirring members 14 may be such that the upper and lower stirring bars 14a are completely overlapped as shown in FIG. 6, but as shown in FIG.
It is desirable that the positions a are different from each other.

A Teflon coating (not shown) is applied to the inner wall of the rotating container 1 and each stirring member 14. Next, the rotational drive mechanism of the rotating container 1 will be explained.
Inside the drive box 6 fixed to the rear surface of the frame 4,
A motor 15 is housed, and the driving force of the motor 15 is transmitted via various gear mechanisms 16 to a rotating shaft 17 protruding from the center of the bottom of the rotating container 1, thereby moving the rotating container 1 at a predetermined speed in the direction of the arrow in the figure. It is designed to rotate.

Next, 18 is a blower mounted on a platform 19 on the base plate 9, and a substantially L-shaped blower pipe 18a is connected to the blower opening at the tip. When in use, the tip of the blow pipe 18a is placed close to the center of the blow and exhaust hole 13 of the lid 1l of the rotary container 1, but when not in use, it is removed to the side as shown in FIG. It is configured so that it can be rotated.

Note that 20 in the figure indicates an operation box provided at the upper end of one of the support columns 7. [Advantageous Effects of the Invention 1] As described above, the device for mixing multiple foods according to the present invention includes a pair of stirring members l4 that rotate together with the rotating container 1, which is rotated so that the axis of rotation is horizontal. Each stirring member 14 has a configuration in which a plurality of stirring bars 14a are arranged in parallel in a straight line at a predetermined interval and are arranged oppositely in two stages. As the food material a repeatedly rises and falls, it hits each stirring bar 14a and breaks, thereby exhibiting an excellent stirring effect.

In other words, compared to a fixed rotating container where only the stirring plate rotates and actively stirs the ingredients inside, the stirring and mixing method uses the natural fall method of the ingredients, so for example, cooked rice, which is inherently viscous, is not required. I don't want to get too involved.

Also, the cooked rice will not stick to the stirring plate and become lumpy. Thus, according to the mixing device of the present invention, it is possible to uniformly mix a plurality of ingredients in a short time, and it is particularly useful as a mixing device for mixing cooked rice and vinegar, which is difficult for amateurs to prepare, that is, for mixing sushi rice.
