[Detailed description of the invention]

[0001]

The present invention relates to a powder supply device for continuously supplying a powdery raw material to a heat treatment machine or the like. The present invention relates to a powder supply device that is most suitable for supplying powder having poor properties.

[0002]

2. Description of the Related Art In recent years, with the diversification of eating habits, many types of processed food materials and instant foods have been marketed. In such a food processing field, a powder heat treatment machine is used. This powder heat treatment machine is provided with a hot air preheating zone, a steam heating cooking zone, and a cold air drying zone in a processing vessel in order, and a transport belt for transporting the powder to be heat-treated is provided in these zones. Is supplied on the conveyor belt in a thin film form, and the powder is successively introduced into the hot air preheating zone, the steam heating cooking zone, and the cold air drying zone by the rotation of the conveyor belt to perform heat treatment.

[0003]

[Problems to be Solved by the Invention] By the way, in the above powder heat treatment machine, in order to make the quality of the final product uniform,
When supplying the powder onto the conveyor belt, it is important to supply the powder on the conveyor belt in the form of a thin film having a constant width and a constant thickness.

However, powders containing high fat, such as egg yolk powder, have many lumps (lumps) and poor fluidity.
It is difficult to supply a thin film having a uniform width and a uniform thickness on the conveyor belt. If the powder is not supplied on the conveyor belt in a uniform width and in the form of a thin film having a uniform thickness, the heat treatment will be insufficient in the thick part and the heat treatment will be excessive in the thin part, and the final product will not be heated. There is a problem that the quality varies.

[0005] The present invention has been proposed in view of the above-mentioned problems, and its purpose is to remove powder having many lumps (lumps) such as high fat content powder and poor fluidity by powder heat treatment. It is an object of the present invention to provide a powder supply apparatus which continuously supplies a thin film having a constant width and a constant thickness onto a conveyor belt of a machine or the like.

[0006]

According to the present invention, in order to achieve the above object, a rotor, which is rotationally driven by a suitable rotational driving means, is arranged in a casing so that its axial direction is perpendicular to the traveling direction of the conveyor belt. Along with disposing in a state, a plurality of agitating pipes for ejecting agitating air are arranged, and a plurality of rotating blades are fixedly mounted at equal intervals on the peripheral surface of the rotor, and further, a lower end opening of the casing is provided. And an upper feeder provided with a punched wire mesh in contact with the rotary blade, and a mesh wire mesh having a predetermined mesh size provided below the upper feeder, and the mesh wire mesh is vibrated in a horizontal direction by an appropriate vibration means. And a lower stage shifter.

[0007]

According to the present invention, the powder supplied to the inside of the casing of the upper feeder is provided with the powder in the casing.
The rotating blade provided on the
Lump is finely crushed by being pressed against the punched wire mesh
At the same time as the lower shift mesh wire mesh
Is distributed on the conveyor belt at a constant width, and
It is supplied in the form of a thin film having a constant thickness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A powder supply apparatus according to the present invention will be described based on an embodiment shown in the drawings.

FIG. 1 is a schematic vertical sectional side view of the device of the present invention, and FIG. 2 is a schematic vertical sectional front view.

As shown in FIGS. 1 and 2, the device of the present invention comprises an upper feeder (A) and a lower shifter (B).

The upper feeder (A) has a rotor (2) rotatably driven by a suitable rotary drive means such as a motor (not shown) inside a casing (1) made of metal (for example, stainless steel). In a direction perpendicular to the running direction of the conveyor belt (3), and a plurality of rotary blades (4) (4)... Are fixedly mounted at equal intervals on the peripheral surface of the rotor (2). In addition, stirring pipes (5) and (5) for ejecting air are respectively disposed on the upper right side and the left side of the rotor (2) in FIG. 1, and further, a punched wire mesh having a number of small holes formed by drilling. (6) is disposed at the lower end opening of the casing (1) so as to be in contact with the rotary blade (4).

In the lower shift (B), a mesh wire mesh (7) having a predetermined mesh size is disposed below the upper feeder (A), and an appropriate vibration means (not shown) is provided on the mesh wire mesh (7). Gives a horizontal vibration motion.

The device of the present invention is configured as described above.
Next, the operation of the device of the present invention having the above configuration will be described.

Casing (1) of upper feeder (A )
A lot of lump such as high-fat-containing powder and the poor fluidity of the powder are put into the stirring pipe (5).
It is stirred by the air jetted from (5) and falls by its own weight onto the punched wire mesh (6), where it is pressed against the punched wire mesh (6) by the rotation of the rotary blade (4), and the punched wire mesh (6).
More mass in the working of (lumps) is dropped onto the lower shift mesh screen (7) in (B) as a powder of fine particles are milled. Thereafter, the mesh wire mesh (7) of the lower shift (B)
The powder that has fallen on the top is evenly dispersed by the vibrating motion of the mesh wire mesh (7) and is continuously supplied onto the conveyor belt (3). As a result, the powder supplied on the conveyor belt (3) exhibits a thin film having a constant width and a constant thickness.

[0015]

As described above, according to the present invention, the lumps (lumps) are finely crushed by the upper feeder and are evenly dispersed by the lower shift.
Even powders with a lot of lump such as high-fat-containing powder and poor fluidity can be supplied as a thin film with a constant width and a constant thickness on a conveyor belt such as a powder heat treatment machine. . Therefore, uniform processing is performed over the entire area, and a remarkable effect is achieved in improving the quality of the final product as compared with the conventional one.
