[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting and stirring raw materials used for kneaded products such as kamaboko.

[0002]

2. Description of the Related Art Conventionally, as a kneading material stirring device, for example, a device provided with a cutter which is rotated inside a container by a cutting drive motor and a stirring blade which is rotated along the inner periphery of the container by a stirring drive motor is known. Are known.

[0003] In this conventional apparatus, the frozen surimi stored in a container is cut into small pieces by a cutter and, at the same time, is stirred and kneaded by stirring blades. In this case, the stirring drive is performed by a hydraulic two-stage switching motor, a two-stage transmission motor,
Alternatively, since a constant speed motor is used, the control is performed at a low speed and a high speed or at a constant speed. In the case of the hydraulic type,
The hydraulic motor automatically changes the rotation speed according to the rotation resistance.
Utilizing the speed property, when shredding the rotation resistance is maximized
In some cases, the stirring blade was rotated at a low speed.

[0004]

By the way, the frozen surimi gradually increases in viscosity as it is shredded, so that the load gradually increases, reaches a peak, and then decreases again.

In order to sufficiently stir the material, it is necessary to rotate the stirring blade at a high speed in a state where the raw material is fine and sufficiently knead the material.

[0006] From this, when two-stage switching or a two-speed or constant-speed motor is used for the agitation drive motor as in the conventional apparatus, the cutting drive motor is rotated at high speed while being subjected to the largest load at the peak. It is necessary to set the motor capacity so that it can respond.

[0007] Therefore, in the conventional apparatus, excessive power is consumed at the peak time.
There is a problem that a large motor having a large motor capacity must be used and the life of the motor is shortened. Further, in the apparatus using the hydraulic motor,
Not suitable for food machinery due to the risk of oil leaks
In some cases, hydraulic pressure sources and their installation locations, piping equipment, etc.
Is required separately, and additional maintenance and inspections are required
It is necessary and inefficient in facilities.

[0008] The present invention has been made in view of the above problems, and has been made so that there is no oil leakage related to hygiene.
Above, the cutting drive motor and the agitation drive motor are exchanged according to the cutting state of the raw material, so that a kneaded material that uses a low-capacity motor as the cutting drive motor and can sufficiently stir and knead the raw material. It is an object to provide a stirring device.

[0009]

In order to solve the above-mentioned problems, a kneading raw material stirring device according to the present invention comprises a cutter rotating inside a container by a cutting drive motor, and a cutter rotating along the inner periphery of the container by a stirring drive motor.

Configuration with a sequencer.

[0010]

The frozen surimi raw material stored in the container is finely cut by the rotation of the cutter driven by the cutting drive motor, and at the same time, the stirring blades driven by the stirring drive motor drive along the inner periphery of the container. The mixture is stirred and kneaded by rotating.

Since the stirring drive motor is provided with a rotation speed switching means, the rotation speed switching means can switch the rotation speed in accordance with the cutting state of the raw material by the cutter.

Therefore, when the raw material sticks and the load reaches a peak, the power consumption can be reduced by setting the rotation speed of the stirring drive motor low by the rotation speed switching means. Can be used as a cutting drive motor, and as the load decreases, the number of revolutions can be increased to shorten the stirring time and increase the stirring efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing a kneading raw material stirring device of an embodiment. In the figure, reference numeral 1 denotes a container, which is formed in a two-part structure including a main body 10 and a lid 11. The container 1 is rotatably supported by the frame 2 and the raw material is charged in a downward and oblique posture, the raw material is stirred and kneaded in an upward and diagonal posture (the posture shown in the figure), and the raw material is reversed and turned in a horizontal posture. Is discharged and cleaned.

A cutting drive motor 3 is mounted on the bottom surface of the main body 10. A cutting rotary shaft 30 directly connected to the cutting drive motor 3 is provided inside the container 1. A knife-shaped cutter 31 is provided.

A stirring drive motor 4 is mounted on the upper surface of the lid portion 11. A stirring rotary shaft 40 directly connected to the stirring drive motor 4 faces the cutting rotary shaft 30 inside the container 1. A container 1 is provided on the stirring rotary shaft 40.
A stirring blade 41 that rotates along the inner circumference of is provided.

Further, the stirring drive motor 4 is provided with rotation speed switching means 5 so that the rotation speed can be switched according to the cutting state of the raw material by the cutter 31. In this case, in the embodiment, the rotation speed switching means 5 includes an inverter 5a for controlling the rotation speed of the stirring drive motor 4 by changing the frequency, and a sequencer 5b for controlling the frequency of the inverter 5a with the passage of time. Have.

In the sequencer 5b, the relationship between the time and the rotation speed of the stirring drive motor 4 is as follows. In the embodiment, the set current of the cutting drive motor 3 is a rated current, and the set current is 70 amperes. The rotation speed of the stirring drive motor 4 is set to 45 rpm, and when the rotation speed exceeds 70 amps, the rotation speed is reduced to 10 rpm, which is the minimum rotation speed. Thereafter, every 5 seconds, the rotation speed is increased by 5 rpm, and the maximum rotation speed is quickly increased. The exchange is repeated to stabilize at a certain 45 rpm.

Next, the operation of the embodiment will be described. The frozen surimi raw material stored in the container 1 is finely cut over time by the rotation of the cutter 31 driven by the cutting drive motor 3, and at the same time, the stirring blades 41 driven by the stirring drive motor 4. Is rotated and kneaded along the inner periphery of the container 1 to be stirred and kneaded.

In this case, the rotation speed of the stirring drive motor 4 is increased by 5 rpm every 5 seconds by the sequencer 5 b of the rotation speed switching means 5. Will be switched.

Therefore, when the raw material sticks and the load increases, the rotation speed of the stirring drive motor 4 is kept low, so that the power consumption is reduced accordingly. Conventionally, the rated current was 115 amps with the motor 37 kw, but this time, the rated current is 70 amps with the motor 22 kw. In addition, since the number of rotations increases as the raw material becomes finer, the raw material can be sufficiently stirred and kneaded by the stirring blade 41.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this embodiment. For example, the time setting and the rotation speed setting of the sequencer can be determined as appropriate.

[0022]

[Effect of the Invention] As described above, in the kneading raw material stirring device of the present invention, there is no oil leak or the like concerning sanitation.
After that, since the rotation speed of the stirring drive motor can be switched according to the cutting state of the raw material, a low-capacity motor can be used for the cutting drive motor, so that power consumption is small and the load on the motor is reduced. Since the motor can be reduced in size, the life of the motor is prolonged, and the raw materials can be efficiently and sufficiently stirred and kneaded.
