Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a vegetable washing device used, for example, to remove mud from radish.

[Conventional technology]

A conventional vegetable washing device of this type will be explained with reference to FIG. In the figure, 1 is a casing, which has a vegetable insertion port 2 and a vegetable removal port 3. 4 are two rotating brushes mounted on shafts within the casing 1;
They are arranged so that the radish 5 can pass between them. 6 is a water injection nozzle provided in the casing 1.

Now, when both rotating brushes 4 are rotated to spray water from nozzles 6 and radish 5 is inserted through vegetable insertion port 2, radish 5 can be washed with water by both rotating brushes 4.

[Problem that the invention attempts to solve]

In the conventional vegetable washing device as described above, since the two rotating brushes 4 pinch and scrub the radish 5 from both sides, the entire circumference of the radish 5 cannot be rubbed evenly, making it impossible to remove mud sufficiently. but also
There was a problem that the radish 5 would be damaged and the product value would drop.

This invention was made in order to solve this problem, and aims to provide a vegetable washing device that can clean vegetables without damaging them by washing vegetables with fog and high-speed swirling airflow. purpose.

[Means for solving problems]

The vegetable washing device according to this invention includes a cylindrical casing having a vegetable insertion port and a vegetable removal port, a narrowing portion formed in the middle of the casing to allow vegetables to pass through, and a narrow portion around the vegetable insertion port of the casing. A plurality of nozzles are arranged and each nozzle injects high-pressure water toward the narrowed part so that each injection center line is sequentially shifted in the same direction at a predetermined angle in the circumferential direction on a virtual circle inside the narrowed part. It is prepared.

[Effect]

In this design, when the high-pressure water injected from the nozzle becomes a vortex of mist inside the casing and narrows down into the constriction, air is sucked into the casing from the vegetable insertion port and high pressure is created inside the casing. Since a swirling high-speed airflow toward the vegetable outlet is generated together with water, the vegetables can be washed by the mist diffused within the casing and the swirling high-speed airflow.

[Example of idea]

Figures 1 to 3 show an embodiment of this invention, with Figure 1 being a longitudinal side view, Figure 2 being a view of Figure 1 seen from the left, and Figure 3 being a line taken along the line in Figure 1. FIG. In the figure, 7 is a cylindrical casing;
It is composed of a large-diameter tube 7a, a small-diameter tube 7b, and a narrowed portion 7c that connects both. 8 is a conical constriction surface formed on the inner surface of the narrowed portion 7c; 9 is a vegetable outlet formed on the open side of the small-diameter tube 7b of the casing 7; and 10 is the opening side of the large-diameter tube 7a of the casing 7. 11 is the vegetable insertion opening formed in the front plate 10; 12 is the front plate 10;
It is an annular water conduit provided around the vegetable insertion opening 11 inside the container, and is connected to a dynamic jet (not shown) through a high-pressure water inlet 13. Reference numeral 14 denotes a plurality of nozzles (six in the drawing) arranged at equal intervals in the annular water conduit 12, and the injection center line a is set at a predetermined angle in the circumferential direction (θ = e.g. 15 degrees) in the same direction, and are each opposed to the narrowed portion 7c.

Now, when high-pressure water is injected from each nozzle 14 all at once, this high-pressure water entrains the air in the large-diameter cylinder 7a, becomes a vortex of mist, and is narrowed down into the narrowed part 7c in a spiral shape by the conical aperture surface 8. , and the narrowing part 7c
is accelerated when passing through. When the degree of vacuum increases due to acceleration at the narrowed portion 7c, the vegetable insertion port 11
Air is strongly sucked in, and a swirling high-speed airflow heading towards the vegetable outlet 9 together with high-pressure water is generated even more strongly. When vegetables are inserted into such a casing 7 through the vegetable insertion port 11, the vegetables are inserted into the vegetable insertion port 1.
The operator rides on the air sucked in from the vegetable insertion port 1 and carries the vegetables along with the spiral high-speed airflow through the constriction part 7c to the vegetable removal port 9.
Just by putting the vegetables in from 1, the washed vegetables come out from the vegetable outlet 9. In addition, the high-pressure water sprayed from each nozzle 14 is dispersed in a mist and forms a vortex, which improves the degree of diffusion of the high-pressure water, helping to spread out the bundles of vegetables and cleaning the insides of the bundles. I can do it.

In the above embodiment, each nozzle 14 is sequentially shifted to the right, so that the spiral progresses clockwise, but it may also be made counterclockwise by shifting each nozzle 14 to the left.

In the above embodiment, if the pressure of the high-pressure water spouted from the nozzle 14 is set at a maximum of about 35 kg/cm ² and can be adjusted to a low pressure, the pressure of the high-pressure water can be adjusted according to the type of vegetables, so the pressure of the high-pressure water can be adjusted to suit the type of vegetables. Effective cleaning can be performed without causing damage.

In the embodiment described above, mud etc. dropped from vegetables can be naturally discharged to the outside from the vegetable outlet 9 of the small diameter cylinder 7b together with pressure water.

[Effect of idea]

As explained above, this invention has the effect of cleaning vegetables without damaging them because they are washed using fog and high-speed swirling airflow.
