Abstract

An object of the present invention is to develop a mechanism capable of more effectively performing processing such as emulsification, dispersion, dissolution, atomization, mixing, or stirring on a processing object with fluidity using an atomization device including a rotor-stator type mixer while an inside of a processing tank is maintained in a pressured state, at atmospheric pressure, or in a vacuum state, and occurrence of a negative pressure state on a center side (inner diameter side) of a rotor is actively suppressed or prevented.
An atomization device comprises a rotor-stator type mixer in a processing tank. The atomization device performs processing such as emulsification, dispersion, atomization, mixing, or stirring on a processing object with fluidity using the rotor-stator type mixer while an inside of the processing tank is maintained in a pressured state, at atmospheric pressure, or in a vacuum state. The atomization device has a mechanism in which the rotating rotor makes the processing object flow at a predetermined pressure or higher.

First claim

The invention claimed is:

1. An atomization device comprising, inside a processing tank, a rotor-stator type mixer including:
a stator having a plurality of openings in a peripheral wall thereof; and
a rotor disposed inside the stator with a predetermined gap in a radial direction between the rotor and an inner peripheral surface of the stator, wherein
the atomization device performs any one or more of emulsification processing, dispersion processing, dissolution processing, atomization processing, mixing processing, and stirring processing on a processing object with fluidity using the rotor-stator type mixer while an inside of the processing tank is maintained in a pressured state, at atmospheric pressure, or in a vacuum state,
the atomization device has a mechanism in which the rotating rotor makes the processing object flow at a predetermined pressure or higher,
the mechanism in which the rotating rotor makes the processing object flow at a predetermined pressure or higher is a mechanism in which, in the rotating rotor, the rotating rotor makes the processing object flow at a predetermined pressure or higher by disposing an additional rotor in the vicinity of an outer periphery of a rotating shaft of the rotor and rotating the additional rotor, and
the additional rotor comprises a stirring blade, wherein
the stirring blade is inclined at an angle with respect to a plane being orthogonal to a direction of the rotating shaft, wherein said angle is between 15 to 70°,
a height of the stirring blade in an axial direction of the rotating shaft is at least 0.32 times as long as the diameter of the rotor.

2. The atomization device according to claim 1 , wherein
the mechanism in which the rotating rotor makes the processing object flow at a predetermined pressure or higher is a mechanism that makes the processing object flow in a direction orthogonal to a rotational direction of the rotor inside the rotor in a radial direction.

3. The atomization device according to claim 1 , wherein
the mechanism in which the rotating rotor makes the processing object flow at a predetermined pressure or higher is a mechanism in which, in the rotating rotor, the rotating rotor makes the processing object flow at a predetermined pressure or higher by further disposing a draft tube in the vicinity of an outer periphery of the rotating shaft of the rotor.

4. The atomization device according to claim 1 , wherein
the rotor-stator type mixer is a rotor-stator type mixer in which a portion in contact with the processing object in an outer side of the rotor in a radial direction is covered with a lid member.

5. A method for manufacturing a product with fluidity, comprising performing any one or more of emulsification processing, dispersion processing, dissolution processing, atomization processing, mixing processing, and stirring processing on a processing object with fluidity using the atomization device according to claim 1 .

6. The method for manufacturing a product with fluidity according to claim 5 , wherein the product with fluidity is a food or drink, a medicinal product, or a chemical product.
