Description

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

[Prior Art 1] Conventionally, as a rotary mixing device for mixing two or more types of raw materials such as foods, the device disclosed in Japanese Patent Publication No. 62-57371 is known.

The rotary mixing device disclosed in this publication has a cylindrical rotary container that is long in the direction of the rotation axis, and is provided with a raw material inlet and an outlet, and has a partition plate inside the rotary container that is obliquely perpendicular to the rotation axis. Because of 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 gomokumeshi, the following problems arise.

(1) If you do not blow cold air into the rotating container when mixing ingredients such as fish, vegetables, etc. with cooked rice at a high temperature, the rice will become sticky and will not have a good flavor and gloss.

(2) Since a partition plate is used as a member for stirring the raw materials, the pressure on the raw materials tends to be strong, making it unavoidable that, for example, cooked rice may be kneaded more than necessary.

(3) Since the rotating container is large and heavy, handling is extremely inconvenient when loading and unloading raw materials or cleaning operations.

The present invention was developed in view of the above-mentioned problems of conventional devices, and is capable of uniformly mixing freshly cooked rice and ingredients for mazegohan in a short time, and also uses a rotating container for cooling air. The purpose of the present invention is to provide a mixing device for a plurality of ingredients that can obtain mixed rice with an overall good flavor and gloss by adopting an internal circulation system.

[Operation] Remove the disc lid from the tip of the stirring container, stand it upright with the opening facing upward, and put freshly cooked rice and various ingredients for mixed rice inside.

After adding the appropriate amount of rice and ingredients in this way,
After closing the disc lid again, place the container on the base box, which is a stirring container, so that the pinion and the rack around the outer periphery of the container engage with each other.

Next, the motor in the base box is driven to rotate the rotating shaft via the chain.

As the rotating shaft rotates, the stirring container rotates via a pinion fixed to the rotating shaft and a rack meshed with the pinion.

When the stirring container rotates in this manner, the cooked rice and ingredients in the stirring container are repeatedly transferred from the state shown in FIG. 6 to the state shown in FIG. 7, and from FIG. 7 to the state shown in FIG. By being stirred at the same time, they are mixed uniformly in a short time.

During this time, when the blower is operated and air is blown into the stirring container through the ventilation/exhaust hole, the air is circulated within the stirring container and exhausted to the outside through the ventilation/exhaust hole.

By cooling the surface of the rice grains and forming a film in this manner, delicious and glossy mixed rice can be obtained [Example J Examples of the present invention will be described below with reference to the drawings.

In the figure, 1 is a cylindrical stirring container with an opening 1aL at the tip, and inside it is a two-stage stirring bar 2 obliquely intersecting the rotation axis.
are supported by the bracket 3 and arranged in parallel.

As shown in FIG. 4, this two-stage stirring bar 2 has a plurality of (eight in this example) branch rods 2b protruding from one side of a main body rod 2a that is directly connected to a bracket 3 at a predetermined interval. The distance β between each branch rod 2b is approximately 4 mm, which is equivalent to 1 grain of rice.
~4.5 mm is appropriate.

Note that the surface of each stirring bar 2 is treated with Teflon.

Further, a disc lid 4 is removably attached to the tip opening 1a of the stirring container 1 by a fastening fitting 5, and a ventilation/exhaust hole 6 is opened in the center of the disc M4.

A taper 6a is formed at the periphery of the air blowing/exhausting hole 6 so as to project outward, to prevent the raw material from spilling out during stirring.

The opening 1a at the tip of the stirring container 1 is used as a hole for inserting and removing ingredients for cooked rice R and mixed rice.

Next, the rotational drive mechanism of the stirring container 1 will be explained.
is a base box, and a motor 8 for driving the stirring container 1 is installed at the inner bottom of the base box.

On the other hand, a pair of bearings 9 are provided on both sides of the upper surface of the base box 7.
．． 9 is mounted, and a rotation axis lO is supported by bearings 9.9 on both sides in parallel with the rotation axis of the stirring vessel 1. A gear 11 is fixed to the center of each rotary shaft IO, and these gears 11 are connected to two gears 12 fixed to the drive shaft 8a of the motor 8 via a chain 13. It is an interlocking connection.

Also, on both sides of each rotation axis lO, there are pinions 14 and 14.
are fixedly installed, and the above-mentioned stirring vessel 1 is connected to them and Nion 14.1.
It is rotatably supported by 4.

That is, an annular rack 1 is provided on both sides of the outer periphery of the stirring container 1.
5 is fixed in an extrapolated state, and both racks 15 are placed in contact with the binions 14.14 on the base box 7, so that the racks 15 and the binions 14.14 are engaged with each other,
The driving force of the motor 8 is transmitted through a chain 13 and a rotating shaft 10 to rotate the stirring container 1 in the direction indicated by the arrow in the figure.

Note that projecting edges 15a are formed on both sides of both racks 15, and the pinions 15a are formed on both sides of the racks 15.
It is designed to prevent disengagement from engagement with 4.

Next, reference numeral 16 in the figure is a blower supported by a support arm 17 on the base box 7, and the blower port 16a at the tip faces the blower/exhaust hole 6 of the shaft of the stirring container 1 at a slight distance. .

Note that this blower 16 is provided with an air volume adjustment mechanism (not shown). Additionally, a cooler may be built in to send cooled air.

[Effect of the invention 1 As described above, the device for mixing multiple ingredients according to the present invention is equipped with the stirring vessel l having the stirring bar 2 diagonally intersecting with respect to the rotation axis, so that the mixing device for mixing multiple ingredients according to the present invention is equipped with the stirring vessel l having the stirring bar 2 diagonally crossed with respect to the rotation axis. It is possible to uniformly mix a plurality of ingredients such as cooked rice and vinegar in a short time without making the rice grains sticky.

In addition, the blower 16 is placed close to the ventilation/exhaust hole 6 of the stirring container 1, and a system for circulating air within the stirring container 1 is adopted, so that the cooling effect on the cooked rice R is extremely large and the cooling effect is excellent. This allows you to obtain mixed rice with a rich flavor and a glossy texture.

Furthermore, since the entire device is small and easy to clean, it is superior to conventional devices not only in terms of handling but also in terms of hygiene and cost.
