Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a dissolving machine for powder and granular materials, and particularly to a dissolving machine for protein powder and granular materials such as egg white powder, which belong to the food industry.

[Prior art]

In recent years, liquid proteins such as egg whites have been pulverized, the granules are stored, and later redissolved in water as needed to return to their original state before being used for food processing. This is widely practiced. However, the physical properties of these powdered proteins are not uniform, and even when they are redissolved, there are a wide range of proteins from poorly soluble to easily soluble. Dissolving machines with various ingenuity have been proposed for dissolving (
Special Publication No. 48-22511, Special Publication No. 54-2674
No. 8, Japanese Unexamined Patent Publication No. 48-40054). However, all conventional dissolvers adopt a type in which raw water is supplied as an annular membrane, so if more than a certain amount of powder or granules is supplied, the water membrane may break or it may be difficult to maintain an unbroken annular membrane. It has been difficult to prepare high-concentration liquid protein for several reasons, including the need to supply more than a predetermined amount of water. Furthermore, the more hygroscopic the powder or granules are, the more they adhere to the inlet and form a layer, and the growth of this adhering layer may clog the inlet.

Therefore, the present applicant has proposed a dissolving machine (patent application filed in 1983).
No. 7199, Japanese Patent Application No. 58-147387)
On the one hand, with regard to the preparation of high-moat liquid protein, we were able to almost achieve the desired goal, but on the other hand, we have not yet achieved sufficient results regarding the problem of stacking the powder and granules at the inlet. That is, the solvent supply pipe is opened in the center of the supply opening formed in the upper lid of the stirring chamber of the above-mentioned dissolver, and a supply passage for powder and granular material is formed surrounding this, and the above-mentioned A rotary disk that receives the supplied solvent and powder is supported so as to be rotatable in the horizontal direction, and a plurality of stirring blades are installed upright on this rotary disk through a narrow gap between the rotary disk and the upper lid. By doing this, we were able to sufficiently improve the dissolution of the powder and granules in the solvent and obtain the desired liquid protein. It is difficult to say that it is perfect to eliminate the harmful effects caused by the layering of powder and granules, and therefore, this layered powder and granules may form granules and mix into the adjusted liquid protein, causing non-homogenization of the liquid protein. There was a risk of being invited. One possible way to prevent this is to temporarily retain the heterogeneous product discharged from the stirring chamber, stir and dissolve it to homogenize it, and then discharge it as a final product. It is better to avoid post-treatment as much as possible, as there is a risk that the temperature of the protein will rise during stirring and adjustment, leading to spoilage of the product, and the viscosity will also increase at the same time as the temperature rise, deteriorating the fluidity.

[Summary of the invention]

The present invention was made in order to solve the above-mentioned drawbacks, and a stirring chamber for raw water and powder is defined in the dissolver, and by rotating this stirring chamber as a whole together with the stirring blade, This is designed to prevent particles from adhering and stacking inside the stirring chamber. Furthermore, in order to promote the discharge of the adjusted liquid protein into the storage tank, stirring blades were provided in the liquid protein discharge section below the rotating stirring chamber to promote the discharge of the liquid protein and prevent its temperature from rising. It is something.

[Embodiments of the invention]

The present invention will be explained below based on illustrated embodiments.

FIG. 1 shows a cross section of the main parts of the apparatus of this embodiment. According to the figure, there is a supply section (1) for powder and granular material and raw water, and an agitation/mixing section (2) for receiving and stirring and mixing these raw materials. and a discharge part (3) for discharging the stirred and mixed product.The stirring and mixing part (2) and the discharge part (3) are installed in the same cylindrical part, and are stored and fixed on the base (B). has been done.

The above-mentioned supply section (1) includes a chute (11) for supplying powder and granular material installed obliquely from the hopper outlet for supplying powder and granular material to a raw material receiving section of the melting machine, and this chute (11) for supplying powder and granular material.
) is a funnel (12) that supplies raw materials to the stirring/mixing section (2), which will be described later, and a water supply pipe (13) that supplies raw water.
It consists of.

This water supply pipe (13) is equipped with a bent resin hose (13a) and a pipe (13b) that covers the tip of the bent resin hose (13a), and this double pipe structure allows the surface of the pipe (13b) to be This prevents dew condensation on the surface, thereby minimizing the adhesion and stacking of powder and granules.

The funnel (12) for receiving the granular material has a straight body part (12a) and an expanded part (12b) expanded above the straight body part, and the straight body part (12a) is connected to the stirring and mixing part ( 2) Top lid (21)
It is fitted and connected to a cylindrical portion (21a') formed at the center.

The upper lid (21) is a large-diameter flat cylindrical member having the cylindrical portion (21a) in the center, and has a protruding step portion (21b) along the circumference of C± formed on its side wall. It is tightly fitted into the straight body part (31) of the discharge part (3).

Immediately below this upper lid (21), a stirring disk (22) with a slightly smaller diameter is arranged in parallel.
) through the connecting pin (23) to the rotating shaft (20
are connected to each other, and a driving source p (not shown) rotates the disk (22) via this rotating shaft (24). Furthermore, a plurality of curved stirring blades (25) are erected on the upper surface of the stirring disk (22) (see Fig. 3).
, raw water (1) subjected to centrifugal force on this disk (22)
It plays the role of increasing the dissolution efficiency of 1) and the powder (P) and promoting the flow and discharge of the obtained high-concentration liquid protein.

Furthermore, the coating disk (2
6) to form a stirring chamber for the powder (P) together with the stirring disk (22), and in the center of this covering disk (26) is an inlet (28a) having approximately the same inner diameter as the upper cylindrical portion (21a). ) is bored and its outer peripheral edge is bent to face the outer peripheral end of the stirring disk (22) to form a ring-shaped outlet for the adjusted liquid protein. Furthermore, a plurality of pins (27) are suspended from the lower surface of the covering disk (26), and these pins (27) are attached to the stirring disk (26).
It is fitted into the drilled hole 2) to prevent relative movement between the two. Therefore, when the stirring disk (22) is rotated, the covering circle ffi (2Ei) also rotates.
The stirring chamber itself will rotate.

In addition, since the gap between the inlet (28a) of the coating disk (2B) and the lower end of the funnel body (12a) is small as shown in the figure, the powder (P) or adjusted liquid protein that is atomized during stirring is will not escape through this gap, and even if the powder (P) tries to adhere to the lower end of the straight body (12a), it can be prevented by the rotational force of the inlet (28a). Therefore, there is no possibility that grain agglomerates caused by adhering powder particles will be mixed into the adjusted liquid protein.

Such adjusted liquid protein reaches the bottom plate (31) of the discharge part (3) from the ring-shaped scarlet outlet of the stirring chamber, but this bottom plate (
31) is sloped, and the discharge port (32) is located below this slope.
), the adjusted liquid protein flows down by its own weight,
It is designed to be discharged into a storage tank (not shown). Note that a cylindrical portion (31a) protruding from the center of the bottom plate covers and protects the rotating shaft (20).

Next, the operation of the dissolving machine having the above configuration will be explained. The powder and granules stored in the hopper are transferred from the hopper outlet to the chute (
11) flows in the direction of the first arrow P, flows down into the funnel <12), and reaches above the stirring disk (22). At this time, even if the granular material contains a large amount of water and is likely to form granular agglomerates, a vibrator (not shown) crushes the granular agglomerates, ensuring that the granular material is placed on the shoe (11). (P) is supplied.

On the other hand, the raw water (W) flows through the water supply pipe (13) in the direction of arrow W by a pump (not shown), and flows through the inlet (28a) of the coating disk.

) is applied with centrifugal force by the stirring disk (22), and is scattered along its upper surface to the outer periphery together with the powder (P).

At this time, the powder is atomized in the stirring chamber under the action of the plurality of curved stirring blades (25), and the dissolution of the powder (P) into the raw water (Ill) is promoted. At this time, the straight body part (12a) of the funnel
A part of the powder (P) adheres to the lower end, but since this is constantly removed by the inlet (2B'a) of the rotating coating disk, the granules falling onto the rotating disk (22) are It does not grow and is supplied as a homogeneous high-concentration liquid protein to the lower discharge part (3) through the guide part (28b) of the coated disk, and then to the inclined bottom plate (31) of the discharge part and the discharge port (3).
The highly concentrated liquid protein is discharged into a storage tank (not shown) via step 3).

2 to 4 show another embodiment of the present invention, which differs from the above embodiment in that a discharge rotor is attached to the liquid protein discharge section (3).

This discharge part (3) is formed as a cylinder, in which a plurality of discharge rotary blades (30) are attached to one rotation shaft (35) (see Fig. 4), and this rotation shaft (35) is a drive shaft. (3

It is connected to the large gear (41) in this gear box (0) via a key (42).The above-mentioned rotating shaft (20) is mounted in this drive shaft (3θ) for relative movement. , the stirring disk (22) is driven to rotate.Furthermore, the large gear (4) meshes with a small gear (42) in contact with the PII, and is mounted below this small gear (42). The rotation i (34) is attached to the rotating shaft (35) through its inner end, and its lower end is connected to the lower end of the rotating shaft (35). It is fixed to a rotating plate (35b) extending outwardly along the discharge part bottom plate (31) so as to define a space above the rotary plate (35b).

Note that FIG. 3 shows a partially cutaway view of FIG. 4.

As a result, the small gear (42) is driven in parallel with the dissolution of the powder (P) into the raw water (W), and the large gear (41) meshing with the small gear (42) and the drive shaft (36) connected thereto. The rotating shaft (35) is driven through the rotating plate (35) to discharge the adjusted liquid protein on the rotating plate (35). At this time, the space above the rotary plate (35) is divided into a plurality of chambers by a plurality of rotary blades (34), and the liquid protein between each rotation E (34) is sequentially discharged from the discharge port (33).
) and can promote the excretion of liquid protein. However, if the rotation speed of the rotary plate (33) is increased beyond a certain level, the opening time of each compartment to the discharge port (33) will be shortened, and the amount of liquid protein discharged may be inhibited due to its viscosity. It is necessary to adjust it accordingly. By promoting discharge in this way, it is possible to prevent the temperature of the liquid protein from rising, and it is possible to maintain it at a low temperature without damaging its quality.Furthermore, there is no increase in viscosity due to temperature rise, and it is possible to prevent the temperature of the liquid protein from increasing. It is effective in promoting
