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 pastry products such as kamaboko, and additives to make a mixed product before molding. It is.

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 uses 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. Because 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 also has high working efficiency due to the raw 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, the long spheroid container 1, as shown in FIG.
It has a long spherical inner surface structure that allows for good raw material flow, and has a two-part opening/closing structure for internal cleaning, blade replacement, etc. Next, the mixed raw material inlet 2 is opened at the upper part of the elongated spherical container 1, and the inlet 2 is equipped with an opening/closing lid 3 having a sliding structure that matches the spherical inner surface of the elongated spherical container 1 in the closed state. are doing.

Further, the mixed product outlet 4 is opened at the bottom of the elongated sphere 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 elongated sphere container 1 toward the center of the elongated sphere, and an electric motor 10 serving as a driving means is directly connected to the coaxial shaft 6.

The scraping blade 7 is provided on the low-speed rotating shaft 6 in a semi-elliptical arc shape along the inner surface of the long spherical container 1, and in the embodiment, as shown in FIG. 7a and a semi-long arc attachment arm 7b, and is an inclined scraping blade that guides the surrounding raw material inward.

Next, the high-speed rotation shaft 8 is disposed obliquely upward from the lower side of the elongated spherical container 1, facing the low-speed rotation 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 hopper, 13 indicates the slide sealing material, and 14 indicates the V.
Belt pulley, 15 is a high-speed rotating shaft surrounding body, 16, 17
18 is a screw cap for attaching and detaching the blade, and 18 is a collar.

The configuration of the mixing agitator according to an embodiment has been explained above, and the configuration includes a long spherical container 1 having a long spherical inner surface structure, a mixed raw material input port 2 equipped with an opening/closing lid 3 opened at the top of the container 1, and the same. 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 diagonally downward from the upper side of the container 1 toward the elongated spherical center, and a low-speed rotating shaft 6 provided on the same axis 6. A half-elongated arc-shaped scraping blade 7 that runs along the inner surface of the container 1 and the low-speed rotating shaft 6 that extends from the lower side of the container 1
a high-speed rotating shaft 8 disposed obliquely upward facing the;
The configuration is not limited to the one shown in the figure, as long as it is a mixing agitator consisting of a plurality of stirring blades 9 provided from the tip to the base end of the coaxial shaft 8. For example, the high-speed rotating shaft 8
As long as it is inclined diagonally upward, the angle of inclination may be any suitable angle, and the axis does not necessarily have to be directed toward the long spherical center of the spherical container 1, but the coaxial 8 may be slightly shifted. It may be provided at any location. Further, the transmission of the driving means to the high-speed rotating shaft 8 is not limited to belt transmission, but may be transmission using a direct connection structure or a coupling structure.

Further, the drive of the low-speed rotating shaft 6 is not limited to direct drive, but may be indirect drive such as belt transmission.

Although not shown, the long spheroid container 1 may have a double wall structure and a heating medium or a cooling medium may be sealed in the wall between them, or a vacuum pump or a pressure pump may be connected to the long spheroid container 1. A mixing/stirring configuration may be used in a vacuum or pressurized state, and in these configurations, since the spheroidal container 1 is used, the pressure-resistant structure is preferable.

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

Therefore, an example of the use of the mixer of the present invention is to add frozen surimi, which is a raw material for a pastry product such as kamaboko, and additives such as water and starch, and to make a mixture of these raw materials before molding. To explain, first, open/close lid 3
is opened and raw material M is introduced into the elongated sphere container 1 through the input port 2. Then, when the opening/closing lid 3 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, as described above. Due to the structure for dumping and discharging the raw material M using gravity, 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 bottom of the long spherical container 1 falls directly onto the stirring blade 9 as shown by arrow a, and the side and top portions are subjected to gravitational action as shown by arrow b and fall to the stirring blade 9. In this state, the raw material from the peripheral part of the long spheroid container 1 is guided and supplied (some mixing and stirring action is also performed at this time), and then the raw material M is supplied to the stirring blade 9, which rotates at high speed (example). Well then
1500rpm/3000rpm) and is arranged in an inclined state, it receives an effective mixing and stirring action and flows the raw material M around the periphery of the long spheroidal container 1 as shown by arrow c. By repeating this process, the raw materials M are mixed and stirred in a short time while constantly flowing in the horizontal and vertical directions.

In other words, regarding the fluidity of the raw material, it has a long spherical container structure that allows for good raw material flow, and it has 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. It has good fluidity, and in terms of mixing and stirring properties, it has a tilted stirring blade structure that effectively mixes and stirs the flow of the raw material M in the direction of gravity, so it has good mixing and stirring properties. It exhibits high mixing and stirring efficiency depending on its properties.

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.
