Description

[Detailed Description of the Invention] Technical Field This invention relates to a powder sifter for sifting out powder such as American flour.

Purpose of the invention The purpose of this invention is to provide a powder sifter that can efficiently and easily sift out powder such as American flour.

EXAMPLE An example embodying this invention will be described below with reference to the drawings.

A sieve net 3 is attached to the bottom of a sieve container 1 which is cylindrical and has reinforcing ribs 2 formed around its center.

A bearing 6 extending vertically is arranged on the inner circumferential surface of the sieve container 1, and the stirring part 4 is rotatably supported by the bearing 6 at an intermediate shaft part 5.

The stirring section 4 includes a stirring section 7 extending parallel to the sieve net 3 on the upper surface of the sieve net 3 and constituting a stirring member, and a stirring section 7 extending from the upper end of the shaft section 5 to the outside of the sieve container 1 and extending downward from the outside of the sieve container 1. It consists of a handle 8 extending laterally from near the vertical center of the container 1, and a grip handle 9 made of synthetic resin is fixed to the handle 8.

Note that 10 indicates a hook fixed to the grip handle 9, and this hook 10 is for hanging this powder sifter when not in use.

The sieve container 1 has a substantially fan-shaped configuration with the shaft portion 5 as the center and the length L of the stirring portion 7 as a radius.

Note that the sieve container 1 is constructed by bending a metal plate,
As shown in FIG. 3, a concealing material 12 made of synthetic resin is fixed to the joining portions of both ends.

Further, a protrusion 13 is formed approximately in the center of the concealing material 12.

Now, in order to sift powder using the powder sifter configured as described above, all you have to do is put flour into the sieve container 1, hold the grip handle 9, and shake the sieve container 1 from side to side.

In this way, as shown by the two-dot chain line in FIG. The powder in 1 is filtered through a sieve net 3 while being stirred.

In this case, in this powder sifter, the sieve container 1 is formed into a substantially fan shape centered on the center of rotation of the stirring section 7, so the stirring section 7 rotates on the upper surface of the sieve screen 3 with almost no gap. As a result, the powder is evenly stirred in the sieving container 1, and efficient powder sieving can be performed.

In addition, since the sieve container 1 is formed into a substantially fan shape, the mass of the portion of the sieve container 1 away from the center of rotation is large, and the centripetal force of the sieve container 1 causes the container 1 to swing from side to side. It becomes easier.

On the other hand, as shown in Figure 4, the conventional powder sifter
Since the sieve container 21 is formed in a cylindrical shape, there is a portion located outside the rotation range of the stirring portion 22 as shown by diagonal lines in FIG. It becomes less efficient.

In addition, in the powder sifter of this embodiment, since the grip handle 9 is arranged at an intermediate position between the upper and lower sides of the sieve container 1,
The sieve container can be stably shaken in a substantially horizontal plane.

In other words, if the grip handle is located at the upper end of the sieve container, the shaking of the sieve container causes the sieve container to swing like a pendulum around the grip handle 9.

Further, a protrusion 13 formed on the concealing material 12 is used to hook a grommet 15 provided at the opening of a bag 14 for storing the sifted powder, as shown in FIG. .

In the rope rope manual, the fan shape includes one in which the arc is approximately 180 degrees long.

Further, in the above embodiment, the stirring part 7 and the handle part 8 are integrally formed, but the stirring part and the handle part may be formed separately.

That is, the stirring part is rotatably supported on the sieve container at its base end, and the handle is rotatably attached or fixed to the sieve container.

Effects of the Invention As exemplified in the examples, this invention has the advantage that powder sieving can be carried out efficiently with simple operation by configuring the sieving container in a substantially fan shape centered on the center of rotation of the stirring member. It has a great effect.
