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.

[Prior Art] 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 to solve this problem, and the purpose is to provide a vegetable washing device that can clean vegetables without damaging them by washing vegetables with fog and high-speed airflow. .

[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 narrowed portion formed in the middle of the casing through which the vegetables pass, and a narrow portion provided on the vegetable insertion port side of the casing. and a nozzle that injects high-pressure water toward the narrowed portion.

[Effect]

In this device, when the high-pressure water injected from the nozzle is diffused in the casing in the form of a mist and narrowed down to the narrowed part, air is sucked into the casing through the vegetable insertion port, and the vegetables are mixed with the high-pressure water inside the casing. Since a high-speed airflow toward the outlet is generated, the vegetables can be washed by the fog diffused within the casing and the high-speed airflow.

〔Example〕

Figures 1 and 2 show an embodiment of this invention, and in the figure, 7 is a cylindrical casing, which includes a large-diameter cylinder 7a, a small-diameter cylinder 7b, and a narrowed part 7c that connects the two. It consists of 8 is the narrowing part 7
a conical aperture surface formed on the inner surface of c; 9 a vegetable outlet formed on the open side of the small-diameter tube 7b of the casing 7; and 10 attached to close the open side of the large-diameter tube 7a of the casing 7. The front plate 11 is a vegetable insertion opening 12 formed in the front plate 10.
The high pressure water inlet 13 is an annular water conduit installed inside the
is connected to dynamic injection (not shown). Reference numeral 14 denotes a plurality of nozzles (six in the drawing) arranged at equal intervals in the annular water conduit 12, each of which faces the narrowed portion 7c so that the injection center line passes through the virtual apex O of the aperture surface 8. .

Now, when high-pressure water is injected from each nozzle 14 all at once, this high-pressure water entrains the air inside the large-diameter tube 7a, becomes a mist, and is drawn into the narrowed part 7 by the conical aperture surface 8.
c, and is accelerated when passing through the constriction part 7c. When the degree of vacuum increases due to the acceleration at the narrowed portion 7c, air is strongly sucked in from the vegetable insertion port 11, and a strong high-speed airflow toward the vegetable removal port 9 together with high-pressure water is generated.

When vegetables are inserted into such a casing 7 through the vegetable insertion port 11, the vegetables are carried by the air sucked in from the vegetable insertion port 11 and are carried along with the high-speed airflow to the vegetable removal port 9 through the constriction portion 7c. The person simply puts vegetables in through the vegetable insertion port 11, and the washed vegetables come out from the vegetable removal port 9. In addition, the high-pressure water sprayed from each nozzle collides with each other in a mist-like state, which spreads the vegetables in the bundle, making it possible to wash the inside of the bundle.

As in the above embodiment, the nozzle 14 is connected to the vegetable insertion port 1.
Arrange multiple nozzles at equal intervals around 1, and each nozzle 1
By making the injection center lines of 4 coincide with the virtual apex O of the aperture surface 8, the high-pressure water hits the vegetables evenly around the vegetables, so that no parts of the vegetables are left unwashed. At this time, if the diffusion angle of the high-pressure water injected from the nozzle 14 is set to 30° to 40° and the high-pressure water is diffused in the form of a mist of large particles on the outside and small particles on the inside, the high-pressure water is restricted to the narrowed part 7c. The cleaning effect is improved, and the cleaning effect is improved because the cleaning effect is evenly distributed all around the vegetables.

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 device cleans vegetables using fog and high-speed airflow, so it has the effect of cleaning vegetables without damaging them.
