Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kneader used for stirring and kneading powdery or granular materials such as wheat flour, meat and chemicals or bricks.

[0002]

2. Description of the Related Art Conventionally, a kneading machine for kneading wheat flour or the like has a rotary blade provided inside a container having a semicircular bottom at the bottom, and the rotary blade is driven to rotate by a motor, so that the added flour and water, etc. Was kneading.

[0003]

However, since the conventional kneader for kneading wheat flour or the like has only one rotary blade inside, when a material having a relatively high viscosity is kneaded, the material is a rotary blade. There was a problem in that the kneading property was poor and the parts were not partially kneaded, resulting in the parts being unkneaded. Furthermore, when attempting to sufficiently knead the raw materials, the kneading will take a long time, resulting in unnecessary power loss and further heat generation of the raw materials. There was a problem that it had to be done. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a kneading machine having good kneading properties and capable of kneading in a short time.

[0004]

A method according to the above-mentioned object.
The kneading machine described is a pair of stirring blades that are connected to a drive source and that are arranged parallel to the meshing distance by changing the mounting phase angle.
An outer plate having a bottom portion having a bicircular cross section formed with a small gap from the outer locus circle of the pair of stirring blades, and a stirring container having an upper opening provided with a flat side plate connected to the outer plate; A kneading machine comprising: the stirring blade, which is cantilevered, is rotatably attached to the opposing flat side plates via respective drive shafts, and the stirring blade has an end portion of the drive shaft. A horizontal rod that is mounted parallel to the flat side plate in close proximity to the flat side plate, and a vertical rod that is connected to the end of the horizontal rod in parallel with the drive shaft and has an outer peripheral portion that forms the outer locus circle. Moreover, the pair of stirring blades are rotationally driven in the same direction.

[0005]

In the kneading machine according to the first aspect of the present invention, the stirring blade is cantilevered and is rotatably attached to the opposing flat side plates through the drive shafts, and the vertical rods parallel to the drive shaft direction are provided. Since it has a horizontal rod arranged in parallel with the flat side plate, when both stirring blades are rotated in the same direction, the raw material is pushed by the vertical rod arranged on the outer side, and the bi-circular motion occurs. do. Then, the raw material inside one of the stirring blades is pushed by the other vertical rod that meshes with the stirring blade and is stirred, so that the raw material is stirred inside the stirring blade without being stagnant. Since the stirring blades are attached to the opposing flat side plates in a cantilevered state, respectively, the effective stirring volume increases and the raw materials arranged near the flat side plate are also stirred.

The stirring blades 12 and 13 are mounted at right angles with their mounting phase angles shifted, and the respective drive shafts 23 have their axial centers sufficiently close to each other.
2 and 13 rotate while meshing with each other.

The power transmission mechanisms 14 and 15 are adapted to rotate the drive shaft 23 in a predetermined direction.
Bearings 28, 2 for rotatably supporting the drive shaft 23

A plurality of 3 are provided. This further improves the stirring efficiency.

It is preferable that the inside of the stirring container of the kneading machine and the surfaces of the stirring blades in the above-mentioned examples are all subjected to Teflon processing to improve the separation of the raw materials. The shape of the stirring blade may be modified as long as it stirs the raw material in the kneading container. Further, the drive mechanism of the stirring blade is not limited to this embodiment, and may be any drive mechanism as long as it is rotationally driven in the same direction at a predetermined speed.

[0015]

As is apparent from the above description, the kneading machine according to the first aspect of the present invention is such that the stirring blade is cantilevered and is rotatably attached to the opposing flat side plates through the drive shafts. A horizontal rod that is disposed in parallel with the flat side plate and is connected to the end of the drive shaft, and a vertical rod that is attached to the end of the horizontal rod in parallel with the drive shaft. Therefore, when both stirring blades are rotated in the same direction, the raw material is pushed by the vertical rod arranged on the outer side, makes a bi-circular motion, and is uniformly stirred. Further, the raw material inside one of the stirring blades is pushed by the other vertical rod which meshes with each other and stirs while giving shearing force. Therefore, stirring of the charged raw materials can be efficiently performed within a short period of time, and the raw materials can be made sticky.
