Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixing agitator that is mainly used when adding frozen surimi, which is a raw material for pastry products such as kamaboko, and additives to form a mixed product before stratification. be.

As shown in Figure 4, conventional mixing agitators can be roughly divided into:
The stirrer J has a horizontal stirring blade structure installed on the vertical rotation axis d, and the stirrer J has a horizontal stirring blade structure installed on the horizontal rotation axis f as shown in FIG. Stirrer J is highly mechanically efficient because the rotating stirring blades act effectively against the flow of input raw materials in the direction of unilateral gravity, but when discharging the stirred raw materials, the stirring vessel is reversed. In addition, it is difficult to remove the stirring raw material adhering to the inner surface of the stirring vessel during inversion, resulting in extremely low work efficiency.

In addition, the other stirrer K (Japanese Patent Application Laid-Open No. 51-28252) with a vertical stirring blade structure has high work efficiency because it uses gravity to input and discharge raw materials in a vertical direction. Stirring blade 1j in the direction parallel to the gravity direction of the raw material
Since g is a rotating device, the flow of the raw material is poor, and especially the left and right sides of the container i are poorly mixed, so it is necessary to mix for a long time, and the mechanical efficiency is extremely low. In view of the drawbacks of conventionally structured mixing agitators, we have completed a new structure mixing agitator that takes advantage of the advantages of both structures and eliminates the drawbacks.The purpose of the present invention is to The object of the present invention is to provide a mixing agitator having a high mixing and agitating efficiency (mechanical efficiency) with a blade structure and a spherical container structure, and a high working efficiency with a raw material dumping and discharging structure using gravity.

The cap, 18 is a collar 0. The configuration of the mixer stirrer of the embodiment-example has been explained above. A mixed raw material inlet 2, a mixed product outlet 4 having an opening/closing opening 1fi5 opened at the bottom of the container 1, and a low-speed rotating shaft disposed obliquely downward from the upper side of the container 1 toward the center of the elongated ball. 6, a half-elongated arc-shaped scraping blade 7 provided on the same axis 6 that follows the circle dj of the container l, and a scraping blade 7 that extends from the lower side of the container 1 to the low-speed rotating shaft 6.
The configuration is not limited to the one shown in the figure, as long as it is a mixing/stirring device consisting of a high-speed rotating shaft disposed diagonally upwards i facing the mixing shaft 8, and a plurality of stirring blades 9 provided from the tip to the base end of the shaft 8. For example, if the high-speed rotating wheel 8 is tilted diagonally upward, the tilt angle may be any suitable angle, and t
The axial center of the spherical container 1 does not necessarily have to be directed toward the long spherical center of the spherical container 1, and the coaxial 8 may be provided at a slightly shifted position. The transmission is not limited to transmission, and may be transmission using a direct connection structure or a coupling structure. Furthermore, the drive of the low-speed rotating shaft 6 is not limited to direct drive, but may be indirect drive such as belt transmission.
