Abstract

PURPOSE:To completely and quickly eliminate foamy particles included in powdery bodies incorporated in mixed liquid by supporting a perforated plate for forcedly passing a stirred flow along a rotary shaft to the outer periphery of the rotary shaft in an axial flow stirrer wherein rotary blades are provided to the rotary shaft supported in a liquid tank. CONSTITUTION:In case of introducing the housing liquid 16 to be mixed into a liquid tank 1 and rotating a rotary shaft 2 to actuate an axial flow stirrer 4, a stirring flow by reflux or convection is caused in the housed liquid 16. At this state, in case of introducing powdery bodies, these are stirred together with the housing liquid 16, the fine particles of the powdery bodies are wetted with the housing liquid 16 and made to mixed liquid. At this time, foamy particles are formed by one part of small massive powdery bodies. In case these foamy particles are transferred with the stirred flow and forcely passed through a perforated plate 5 for forceful pass, they are finely divided, crushed and eliminated because the diameter of the foamy particles is larger than the pore diameter of numerous holes of the perforated plate 5. Then respective fine particles included in the foamy particles are wetted respectively with the housing liquid 16, mixed and made to uniform mixed liquid of powdery bodies.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to an apparatus for mixing soybean flour and the like for tofu production with a liquid such as water in a water tank.

``Prior Art'' Conventionally, an apparatus that supports an axial flow stirrer in a water tank and mixes water and soybean flour by introducing them into the same water tank has been generally used in the production of tofu. The above-mentioned flours include not only soybean flour but also wheat flour, skim milk powder, etc., and can be used in food manufacturing industries other than tofu manufacturing. As shown in Figure 6, the above-mentioned powder forms foam-like grains, and since the powder inside the foam-like grains is difficult to dissolve in water, the foam-like grains are scooped out, aggregated, and broken up manually. However, it was difficult to completely eliminate the foamy particles.

"Problems to be Solved by the Invention" The present invention aims to provide a liquid/powder mixer that can almost completely and quickly eliminate foam particles encapsulating powder in a mixed liquid.

"Means for Solving the Problems" The present invention provides an axial flow agitator in which a rotating shaft supported in a liquid tank is provided with rotating blades, and a perforated plate for forced passage of stirring flow along the rotating shaft. It consists of a liquid/powder mixer supported on the outer periphery.

"Operation" Therefore, when the mixing liquid 16 is stored in the liquid tank 1 and the rotating shaft 2 is rotated once to rotate the rotating blades 3 and the axial flow stirrer 4 is operated, the stored liquid 16#i flows along the rotating shaft 2. After flowing, it flows in the opposite direction along the inner surface of the liquid tank 1, and flows again along the rotating shaft 2, producing an agitation flow due to circulation or convection. In this state, when the powder is introduced, the powder is stirred with the storage liquid 16 by the stirring flow, and the fine particles of the powder are mixed with the storage liquid 1.
6 and becomes a mixed liquid. However, when the powder is introduced, the L1 small lump powder forms nominal grains 11, but these foam grains 11 also flow along the rotating shaft 2 with the stirring flow and forcibly move the porous plate 5. When passing through the porous plate 5, the diameter of the foam particles 11 is
The bubble-like particles 11, which are larger than the pore diameters of the countless pores, are subdivided, crushed, and dissolved, and each fine particle is wetted by the contained liquid 16 and mixed into the same wave 16. .

``Example'' A liquid tank 1 is supported on a t@ frame, a reduction motor 7 is provided on a support frame 6 installed at the upper end opening, and the output rotating shaft 2 of the motor 7 is extended to the bottom of the liquid tank l. Two screw rotary vanes 3.3 are provided at the bottom of the rotary shaft 2 via rllglI.

Immediately below the upper rotary blade 3, there is a boss portion 10 of a perforated plate 5, which is made of a circular outer frame 8 with a wire mesh 9 stretched over it as shown in FIG.
A rotary vane-shaped perforated plate 5 as shown in FIGS. 1 and 4 can be provided between the two vanes 3.3.

Although the mesh of the wire mesh 9 of the perforated plate 5 shown in FIG. 3 can be selected and designed as appropriate, a mesh or mesh having a diameter smaller than the diameter of the foam particles 11 shown in FIG. 6 is used. In place of the above-mentioned wire mesh 9, a perforated punched board or a lath may be used.
The boss 81SlO is fixed to the rotation shaft 2 with the set bolt 12 [g1 is rotated together with the rotation shaft 2, or the boss portion 10 is freely supported on the rotation shaft 2, and the outer frame 8 is fixed with a horizontal arm (not shown). It may be supported by a liquid [1 or a stirring flow 11JFJ13. The perforated plate 5 may be formed in the shape of a bottomed basket with an open top end, as shown in FIG. 5, or the bottom surface of the liquid tank 1 may be formed into an inverted conical hopper. Note that 14 in the figure is a mixed liquid discharge pipe, and 15 is an on-off valve provided in the intermediate pipe 14.

``Effects'' As described above, the present invention has the structure L4, so that the countless foam particles encapsulating the powder formed by the powder added to the liquid contained in the chamber forcefully move the porous plate along with the stirring flow. Since the foamed particles are crushed and dissolved by the passage, a powder mixture without foamy particles can be quickly obtained.
