Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixing agitator mainly used when adding frozen surimi, which is a raw material for a pastry product such as urahoko, and additives to make a mixed product before molding. It is something.

Conventional mixing agitators can be roughly divided into agitators J, which have a horizontal stirring blade e structure installed on a vertical rotation axis d, as shown in Figure 4, and an agitator J, which has a horizontal stirring blade e structure installed on a horizontal rotation axis f, as shown in Figure 5. The stirrer K has a vertical stirring blade g structure, and the stirrer J has a horizontal stirring blade structure. Although it is highly efficient, it is necessary to invert the stirring vessel h when discharging the stirring raw material, and it is difficult to remove the stirring raw material that adheres to the inner surface of the stirring vessel h when inverting, so the work efficiency is reduced. was extremely low.

In addition, the stirrer K with the other vertical stirring blade structure
(Japanese Patent Application Laid-open No. 51-28252) has high work efficiency because it has a vertical input/discharge structure that utilizes gravity to input and discharge raw materials, but it has a stirring blade g in a direction parallel to the gravity direction of input raw materials. Since the container i rotates, the flow of the raw materials is poor, and mixing from left to right in the container i is particularly poor, requiring long mixing times, resulting in extremely low mechanical efficiency.

The present invention was made by researching in view of the drawbacks of the conventional mixer and stirrer structure as described above, and completed a mixer and stirrer with a new structure that takes advantage of the advantages of both structures and eliminates the drawbacks. The purpose of this invention is to provide a mixing agitator that has high mixing and agitating efficiency (mechanical efficiency) due to the inclined agitating blade structure and spherical container structure, and high work efficiency due to the material dumping and discharging structure that utilizes gravity.

Next, the mixing agitator of the present invention will be explained in detail below with reference to an embodiment shown in the drawings.

First, as shown in FIG. 1, the rotating columnar container 1 has an inner surface structure similar to that of a sphere with good material flow, and has a two-part opening/closing structure for internal cleaning and blade replacement.

Next, the mixed raw material input port 2 is opened at the top of the rotating columnar container 1, and the input port 2 is provided with an opening/closing lid 3 having a sliding structure that matches the inner surface of the rotating columnar container 1 in the closed state. Equipped with

Further, the mixed product outlet 4 is opened at the bottom of the rotating columnar container 1, and the outlet 4 is also provided with an opening/closing lid 5 like the input port 2.

In the embodiment, the mixed raw material inlet 2 is opened wider than the mixed product outlet 4 to facilitate the input of the raw material, since a lump of frozen surimi may be input as the raw material.

Next, a low-speed rotating shaft 6 is arranged diagonally downward from the upper side of the rotating columnar container 1 toward the axis, and an electric motor 10 serving as a driving means is directly connected to the same shaft 6.

The scraping blade 7 is provided on the low-speed rotating shaft 6 in a bent shape so as to follow the inner surface of the rotating columnar container 1, and in the embodiment, as shown in FIG. and a bent attachment arm 7b, as well as an inclined scraping blade that guides the surrounding raw material to the inner surface.

Next, the high-speed rotating shaft 8 is disposed obliquely upward from the lower side of the rotating columnar container 1, facing the low-speed rotating shaft 6, and the coaxial shaft 8 is equipped with an electric motor (not shown) as a driving means. (not shown) are connected by belt transmission, and the coaxial 8 has a mechanical seal structure to withstand high-speed rotation.

A plurality of stirring blades 9 (three in the embodiment) are provided from the tip to the base end of the high-speed rotating shaft 8, and the blade surface of the blade 9 is the lower blade surface. As shown in FIG. 3, a plurality of S-shaped stirring blades 9 are arranged with the rotational direction phase shifted.

In the figure, 11 indicates the machine frame, 12 indicates the mixed raw material input hopper, 13 indicates the slide sealing material, and 14 indicates the machine frame.
is a V-belt wheel, 15 is a high-speed rotating shaft surrounding body, 16,
17 is a screw cap for attaching and detaching the blade, and 18 is a collar.

The structure of the mixing agitator according to an embodiment has been explained above, and the mixed raw material inputting device is equipped with a rotating columnar container 1 having an inner surface structure of a rotating column similar to that of a sphere, and an opening/closing lid 3 opened at the top of the container 1. Mouth 2 and
A mixed product outlet 4 having an opening/closing lid 5 opened at the bottom of the container 1, a low-speed rotating shaft 6 disposed obliquely downward from the upper side of the container 1 toward the axis, and a low-speed rotating shaft 6 disposed on the same shaft 6. A scraping blade 7 having a bent shape along the inner surface of the container 1, a high-speed rotation shaft 8 disposed obliquely upward from the lower side of the container 1 facing the low-speed rotation shaft 6, and a tip end of the same shaft 8. The mixer is not limited to the configuration shown in the drawings as long as it has a plurality of stirring blades 9 provided from the to the base end, for example,
As long as the high-speed rotating shaft 8 is tilted diagonally upward, the inclination angle may be any suitable angle, and the axis does not necessarily have to be directed toward the axis of the rotating columnar container 1; 8 may be provided at a slightly shifted position.

Further, the high-speed rotating shaft 8 and the low-speed rotating shaft 6 may be driven by direct drive or indirect drive such as belt transmission.

Although not shown, the rotating columnar container 1 may have a double wall structure in which a heating medium or a cooling medium is sealed in the wall between them, or the rotating columnar container 1 may be connected to a vacuum pump or a pressure pump. It is also possible to connect them and mix and stir in a vacuum or pressurized state.

Further, a pipe may be provided around the upper end of the mixed raw material input hopper 12 to flow out in a shower state.
In this case, it is possible to prevent the raw material from adhering to the hopper 12.

Therefore, one example of use is to use the mixing agitator of the present invention to add frozen surimi, which is a raw material for a paste product such as urahoko, and additives such as water and starch, and to make a mixture of these raw materials before molding. To explain, first, the opening/closing lid 3
is opened and the raw material M is fed into the rotating columnar container 1 from the input port 2.
Insert it inside. Then, when the opening/closing lid 5 is closed and the high-speed rotating shaft 8 and the low-speed rotating shaft 6 are rotated, the raw materials M are mixed and stirred by the stirring blade 9 and the scraping blade 7. Next, by opening the opening/closing lid 5, most of the raw material M that has been mixed and stirred in a short time can be discharged to the outside from the discharge port 4 by the action of gravity. Due to the structure for dumping and discharging the raw material M used, there is no need for operations such as reversing the container, and the work efficiency is extremely high.

As shown in FIGS. 2 and 3, the mixing and stirring action of the raw material M is caused by low-speed rotation (in the example,
100 rpm), the scraping blade 7 moves directly to the stirring blade 9 at the bottom of the rotating columnar container 1 as shown by arrow a, and the gravitational force is applied to the stirring blade 9 at the side and top as shown by arrow b. The raw material M from the peripheral part of the rotating columnar container 1 is guided and supplied into the falling state (some mixing and stirring action is also performed at this time), and the raw material M supplied to the stirring blade 9 is then rotated at high speed ( In the example, the rotation speed is 1,500 rpm/3,000 rpm), and since it is arranged in an inclined state, it receives an effective mixing and stirring action, and the raw material M flows around the rotating columnar container 1 as shown by the arrow c. By repeating these operations, the raw material M is mixed and stirred in a short time while constantly flowing in the left-right direction and the up-down direction.

In other words, regarding the fluidity of the raw material, it has a spherical container structure that allows for good raw material flow, and a three-dimensional flow structure that utilizes the force and gravity of the scraping blades 7 and stirring blades 9 installed in an inclined state, so it is extremely fluid. In terms of mixing and stirring properties, the inclined stirring blade structure effectively mixes and stirs the flow of the raw material M in the direction of gravity. It shows high mixing and stirring efficiency.

The mixer of the present invention can also be used to mix and stir various materials such as wheat flour. Furthermore, although an embodiment is shown in which the scraping blades 7 and the stirring blades 9 rotate in opposite directions, they may rotate in the same direction.

Since the mixer of the present invention can be configured and used as described above, it has good workability and is effective in mixing and stirring various raw materials in a short time.
