Description

[Detailed Description of the Invention] The present invention relates to a potato sterilizer, and particularly to a potato seed sterilizer.

Conventionally, the quality of potato seed potatoes in particular has affected subsequent growth and yield, and if seed potatoes with disease are used, the yield will be halved. In other words, there are various types of potato diseases, including those with abnormalities on the surface of the potato such as lesions, soft rot, and mold, and those with abnormalities inside the potato such as discoloration, cavities, and blackening.

For this reason, seed potatoes harvested in the fall are stored until transplanted in the spring of the following year, but the seed potatoes must be disinfected before being stored.

In the unlikely event that disinfection is not performed, even a small amount of seed potatoes with the late blight disease will spread the bacteria to healthy seed potatoes during the storage period, promoting the onset of the disease. Note that this disinfection can be performed in early spring.

Conventionally, the method of sterilizing this kind of potato was to put a prescribed chemical solution in a bathtub and manually soak the container containing the potatoes in the bathtub. However, this method required a large amount of labor, was time-consuming, and had the disadvantages that the chemical solution quickly became contaminated with dirt and other substances adhering to the potatoes.

The present invention was created in view of this point of view, and an object of the present invention is to provide a potato sterilization machine that makes it possible to disinfect potatoes extremely easily.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are a plan view and a side view of the present invention.

The figure shows a frame 10 in which the bathtub section 8 and the wind tunnel section 9 are integrated, a conveyor 3 that quickly transfers the container 2 containing the potatoes 1 from the bathtub section 8 to the wind tunnel section 9, and a system that uniformly distributes the chemical solution 7 to the potatoes 1. It is composed of a chemical liquid distribution device 4, a pump 6, a chemical liquid circulating section such as a storage tank 11, and the like.

In the present invention, the container 2 for storing the potatoes 1 used has a mesh-like side plate and a bottom plate,
The container 2 is configured so that the chemical solution 7 contained therein is quickly discharged to the outside.

The frame 10 consists of a bathtub part 8 and a wind tunnel part 9, and a partition plate 12 is provided between them. This bathtub part 8 is filled with the chemical solution 7 through a circulation part, and while the container 2 containing the potatoes 1 is transferred through the circulation part, the drug solution 7 can be applied uniformly to the potatoes 1.

The wind tunnel section 9 is for drying and draining the potatoes 1 processed in the bathtub section 8, and is equipped with a blower 1.
Compressed air is blown onto the potato 1 by a blowing nozzle 14 connected to the tube 3. Further, the lower plate of the wind tunnel section 9 is inclined, and a ventilation hole 15 is provided above the storage tank 11 so that a small amount of the chemical solution 7 separated from the potato 1 flows through the wind tunnel section 9.

The frame 10 configured as described above is provided with legs 17 to which wheels 16 necessary for moving the disinfection machine of the present invention are attached.

Moreover, the conveyor 3 smoothly transfers the container 2 containing the potatoes 1 from the bathtub part 8 to the wind tunnel part 9, and the bathtub part 8 is installed inside and the wind tunnel part 9 is installed in the upper part.

The method of installing the conveyor 3 in this bathtub section 8 is to install a gentle downward slope so that the lower part of the container 2 is gradually immersed in the chemical solution 7 from the entrance.
The central part where the chemical solution 7 is sprayed from above the container 2 is horizontal, and the wind tunnel part 9 side has a gentle upward slope.

Note that the conveyor 3 in the wind tunnel section 9 is configured horizontally.

Containers 2 on the downhill and horizontal conveyor 3 are moved lightly by hand, so a roller conveyor, foil conveyor, etc. without a power source is used, and the uphill section is forcibly moved by a drive device 18 such as a motor. A conveyor belt or the like is used to transport the material.

In the illustration, the upward slope conveyor 3 is a belt conveyor, but it may also be a roller conveyor, a foil conveyor, or the like.

The chemical liquid circulation section is configured to uniformly spray the chemical liquid 7 onto the potato 1 from above, as shown in FIG. A cover 19 is attached above the center of the bathtub section 8 of the frame 10, and a chemical solution spraying device 4 is installed above the inside.

The chemical solution spraying device 4 is provided with a plurality of discharge ports 20 at positions where the chemical solution 7 can be discharged toward the container 2 in which the potatoes 1 are stored.
is connected to a pump 6 inside a storage tank 11 containing a chemical solution 7 through a hose 5.

The storage tank 11 is separate from the frame 10 and is located below the frame 10, and its upper surface is open and the chemical solution 7 flows down from a drop port 21 provided on the lower plate of the bathtub portion 8 of the frame 10. The bottom plate 22 of the storage tank 11 is inclined, and the mud 23 and the like attached to the potatoes 1 are allowed to settle at the lowest part thereof.

Moreover, the pump 6 inside the storage tank 11
This is a configuration in which the suction port 24 is arranged in a position where the settled mud 23 on the bottom plate 22 is not sucked in, and the chemical solution 7 is pushed out to the chemical solution spraying device 4.
The chemical solution 7 flowing out from the discharge port 20 is sprayed onto the potato 1, temporarily accumulates in the bathtub portion 8, returns to the storage tank 11 through the drop port 21, and circulates.

When the valve 25 is adjusted so that the flow rate of the discharge port 20 is higher than the flow rate of the drop port 21, the chemical solution 7 accumulates inside the bathtub section 8, and the water level gradually rises to the lower end of the extraction hole 26 provided in the side plate of the frame 10. When the chemical liquid 7 reaches the water level, it flows down from this hole 26 into the storage tank 11, and the water level is maintained and the chemical liquid 7 flows out from the frame 10.
will not leak out.

As is clear from the above explanation, in the present invention, the conveyor 3 is installed in the potato sterilizer 1, and the chemical solution 7 can be attached to the potatoes 1 while the container 2 containing the potatoes 1 is being moved. Compared to the method of making and soaking in the drain, it requires less labor and can be processed in a shorter time.

In addition, since the bathtub part 8 and the storage tank 11 are separated, the mud that has separated from the potato 1 is transferred to the storage tank 11.
This invention relates to a disinfectant machine having a simple structure, which has the advantage that the chemical solution 7 inside the bathtub part 8 is always clean because it is collected at the bottom of the bathtub part 8.
