Summary of the Invention

Problems to be Solved by the Invention

[0004] Although the above-described powder mixing apparatus discloses a mixing apparatus that improves the mixing efficiency by changing the return flow direction of the powder to be mixed, it is considered that there is room for further improvement.

[0005] Therefore, an object is to provide a powder processing apparatus that can improve the mixing efficiency.

Means for Solving the Problems

[0006] In order to solve the above problems, the present invention includes a storage container for storing powder particles, a vertical rotating blade disposed vertically inside the storage container, and an inclined rotating blade disposed inclined inside the storage container. The vertical rotating blade is disposed offset from the axis of the storage container in the vertical direction and in a plan view. An inverted truncated cone shape that narrows towards the base The inclined rotating blade is disposed inclined from the bottom to the side of the storage container. Upward in a direction And, The inclined rotating blade is disposed inclined from the bottom to the side of the storage container. Middle section in a direction Ascending at an angle that penetrates and protrudes The inclined rotating blade is disposed inclined from the bottom to the side of the storage container. death,The present invention provides a powder processing apparatus that, when powder or granular material is stored inside the storage container, agitates the powder or granular material by the rotational operation of the vertical rotating blades and the inclined rotating blades that are immersed in the powder or granular material. [Effects of the Invention]

[0007] The powder processing apparatus of the present invention stores powders and granules. An inverted truncated cone shape that narrows towards the base The device comprises at least a storage container, vertical rotating blades arranged vertically inside the storage container, and inclined rotating blades arranged at an angle inside the storage container. When powder or granular material is stored inside the storage container, the rotational operation of the vertical rotating blades and the inclined rotating blades, which are immersed in the powder or granular material, stirs the material. This allows for stirring of the powder or granular material stored in the storage container in different directions of circulation, thereby increasing the mixing efficiency.

[0008] Furthermore, the vertical rotating blades are positioned vertically and in a plan view from the axis of the storage container. Upward Because the vertical rotating blades are positioned offset from each other, the distance between the vertical rotating blades and the storage container becomes uneven. Under this structure, the vertical rotating blades rotate and the powder and granular material are stirred, so a different stirring effect can be expected compared to stirring under a uniform structure where the vertical rotating blades are positioned at the axial center of the storage container. In addition, the inclined rotating blades are positioned from the bottom to the side of the storage container. Middle section Towards Ascending at an angle that penetrates and protrudes Because the container is positioned at an angle, the powdered material stored in the container is agitated against gravity from the bottom of the container toward the sides, which is thought to improve mixing efficiency.

Embodiments for Carrying Out the Invention

[0010] It is implemented as a food powder particle processing device that introduces multiple types of flour into a storage container for processing (stirring).

Examples

[0011] First, the configuration of the powder particle processing device will be described according to FIGS. 1 to 4.

[0012] The powder particle processing device (1) includes at least a storage container (10) capable of storing a certain amount of powder particles, An inverted truncated cone shape that narrows towards the base a vertical rotating blade (21) and an inclined rotating blade (22) installed inside the storage container (as shown in FIGS. 1 to 3).

[0013] The vertical rotating blade (21) is offset from the axis of the storage container (offset upward from the axis shown in FIG. 4) and is arranged vertically inside the storage container (FIG. 4). Top view shifted (shifted upward from the axis shown in FIG. 4) and disposed vertically inside the storage container (FIG. 4).

[0014] Regarding the rotation direction of the vertical rotating blade (21), in this embodiment, both forward rotation and reverse rotation are possible.

[0015] The inclined rotating blade (22) is arranged to slope upward from the bottom of the storage container (10) toward the middle of the side surface At an angle of penetrating protrusion (see FIG. 3).

[0016] The inclined rotating blade (22) is provided so as to project through the middle of the side surface of the storage container (10) (see FIG. 3).

[0017] Next, the operation of the powder processing apparatus will be described according to FIGS. 5 to 11.

[0018] Open the outer lid (31) of the supply port of the powder processing apparatus, press the inner door (32) with a packaging bag (the tip portion of which has been previously opened) containing the first flour (41), and supply the flour in the packaging bag (see FIGS. 5 and 6).

[0019] In order to suppress the scattering of powder particles to the outer periphery of the supply port, the inner door weight (33) is structured to move upward in conjunction with the pressing of the inner door (32) (arrow in FIG. 5).

[0020] The first flour (41) supplied from the supply port is conveyed along the inclined rotating blade by the rotation of the inclined rotating blade (22) and introduced into the interior of the storage container (10) (see FIG. 7).

[0021] Thereafter, press the inner door (32) with a packaging bag (the tip portion of which has been previously opened) containing the second flour (42) of a type different from the first flour, and supply the flour in the packaging bag (see FIGS. 8 and 9).

[0022] The second flour (42) supplied from the supply port is conveyed along the inclined rotating blade by the rotation of the inclined rotating blade (22) and introduced into the interior of the storage container (10) (see FIG. 10).

[0023] Subsequently, by rotating the vertical rotating blade (21) in the forward direction, the submerged portions of the first flour (41) and the second flour (42) stored in the storage container (10) are stirred under the aforementioned non-uniform structure (arrow in Figure 11).

[0024] Furthermore, the rotation of the inclined rotating blade (22) (Tilting rotation) This also causes the first flour (41) and the second flour (42) stored in the storage container (10) to be stirred in the portion that is submerged (arrow in Figure 11).

[0025] The rotational operation of the vertical rotating blade (21) and the inclined rotating blade (22), which are immersed in the first flour (41) and the second flour (42), stirs the flour, thereby increasing the mixing efficiency by performing stirring in different directions on the flour stored in the storage container.

[0026] In this embodiment, we have described a food-type powder processing apparatus that introduces first and second flours into a storage container, but we believe that powder processing apparatuses that introduce other powders into a storage container will operate similarly. [Industrial applicability]

[0027] The present invention is an excellent powder and granular material processing apparatus capable of improving stirring performance and has industrial applicability. [Explanation of Symbols]
