Abstract

(57) [Summary] [Purpose] Effectively stir the flaky or strip-shaped solid matter. [Structure] A flat plate is spirally wound around an outer periphery of a drive shaft that is vertically installed and rotatably formed to form a stirring blade. The radius of gyration of the stirring blade is made smaller toward the upper side so that the object to be stirred does not get entangled with the stirring blade.

[Detailed description of the device]

[Industrial applications]

 The present invention relates to an improvement in a stirrer for flake-shaped or strip-shaped solid matter.

[0002]

[Prior art]

 Conventionally, stirring of solid matter includes rotating the container, operating a stirring blade in the container, and the like. Specific examples include a "stirring screw" (actual fair 3-44254) in which the stirring blade is formed in a ribbon screw type, or a "vertical mixing device" (special fair 2-17218) in which an auxiliary blade is installed. be able to.

[Problems to be solved by the device]

 However, all of the agitators described above are intended for granular solids, and when a strip-shaped object is stirred, such as the kelp extraction residue containing water, the object to be agitated is left on the agitating blade. It became entangled dumplings and was not suitable for stirring these items.

In view of the present situation, the inventors of the present application have conducted earnest research and as a result, installed the stirring blade vertically, formed it into a spiral shape, and formed the rotating radius of the blade gradually smaller toward the upper side. The inventors of the present invention completed the present invention by discovering that the agitated material gradually drops downward as it rises and is not entangled in the agitating blade.

That is, according to the present invention, a stirring blade is formed by spirally winding a flat plate around the outer periphery of a drive shaft that is vertically installed and rotatably formed, and the rotation radius of the stirring blade is increased. It is a stirrer characterized by being configured in accordance with the above.

Means for Solving the Problem First, in FIG. 1, reference numeral 1 denotes a cylindrical container, the upper part of which is open. A stirring blade 2 is installed vertically inside the container 1 so as to be rotatable by a motor 3. The stirring blade 2 is composed of a drive shaft 4 connected to the motor 3 and a blade 5 formed by spirally winding a flat plate around the outer peripheral portion of the shaft 4.

As shown in FIG. 1, the blade 5 is formed so that the radius of rotation becomes smaller as it goes upward. The ratio of the maximum radius of gyration at the bottom to the minimum radius of gyration at the top is about 0.3 to 0.7, and the pitch is not particularly limited, and may be evenly spaced or unequally spaced.

With this structure, as the object to be stirred rises, the object to be stirred is surely removed from the stirring blade 5 and is not entangled with it.

Next, an example in which the device of the present application is applied to an extraction / drying device is shown in FIGS. In the present embodiment, the jacket 1 and the stirring blade 5 are provided with cavities 7 and 8 in the container 1 so that the heating source can be supplied and the indirect heating device is formed.

The bottom 9 of the container 1 is formed of a metal net or a perforated plate so that the extract can be discharged from the container 1. Reference numeral 10 is an extraction liquid container that stores the extraction liquid.

In carrying out this embodiment, first, hot water is poured from the upper part of the container 1, and the extract is extracted from the kelp that has been cut into pieces. Then, after extraction, it is dried, for example, for feed, and the device of the present application works effectively in this case.

That is, even if the sticky kelp extract residue contains a large amount of water, it is turned upside down as described above without being entangled with the stirring blade 5, dried by an indirect heating device, and then pulverized to be a product. To be done.

[0013]

[Effects of the Invention] In spite of the simple structure as described above, the present invention can stir the substance to be stirred without entwining it with the stirring root.
