Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a preserving device for maintaining the freshness of fresh plants such as fruits, vegetables and flowers.

[0002]

2. Description of the Related Art When fresh plants and the like are stored for a long time in a storage room, the fresh plants are promoted by aging and aging due to ethylene discharged by respiration, and their freshness is impaired. Freshness equipment is used.

As shown in FIG. 2, a conventional preserving device is a mercury lamp that emits ultraviolet rays having peaks at wavelengths of 184.9 nm and 253.7 nm in a unit body 1 having an air inlet 5 and an air outlet 2, and an ultraviolet ray. An ozone generating means 6 including a lamp and the like, a metal catalyst such as activated carbon, manganese, iron, cobalt, and palladium, or an ozone decomposing means 7 including these metal oxidation catalysts, and a blower 3 are provided.

When electricity is supplied to the ozone generating means 6 and the blower 3 to operate them, the inside air containing ethylene discharged from the fresh plants stored in the refrigerator 4 enters the housing 1 through the air suction port 5. In the process of being sucked and flowing around the ozone generating means 6, the oxygen in the air inside the refrigerator is converted by the ultraviolet rays having a peak at a wavelength of 184.9 nm emitted from the ozone generating means 6. This ozone kills microorganisms, bacteria, etc. floating in the air in the refrigerator, decomposes offensive odor components, and at the same time oxidizes ethylene contained in the air in the refrigerator to convert it into ethylene compounds such as ethylene oxide and acetaldehyde.

The surplus ozone is decomposed into oxygen and nascent oxygen by the ultraviolet rays emitted from the ozone generating means 6 and having a peak at a wavelength of 253.7 nm. Oxygen in this nascent stage oxidizes ethylene remaining in the air in the refrigerator and converts it into an ethylene compound.

Next, during the process of the air flowing through the ozone decomposing means 7, the ozone remaining in the air is decomposed into oxygen, and the ethylene compound is adsorbed and removed. After this, this air is urged by the blower 3 to flow from the air outlet 2 to the refrigerator 4
Is blown out.

[0007]

Since the conventional preserving device is installed in the storage 4 and cannot be moved, it is not possible to preserve the fresh plant during its collection and delivery.

[0008]

The present invention has been invented in order to solve the above-mentioned problems, and the gist of the invention is that an ozone generating means, an ozone decomposing means, and a blower are provided inside. A unit body having an air inlet and an air outlet, a generator for generating electricity to supply the ozone generating means and the blower, and an engine for driving the generator mounted on a moving carriage. It is in a possible preserving device.

Then, the mobile carriage is moved to a place where fresh plants are accumulated, and the generator drives the engine there to supply the generated electricity to the ozone generating means and the blower.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the invention is shown in FIG. An ozone generating means 6, an ozone decomposing means 7 and a blower 3 are arranged inside a unit main body 1 having an air inlet 5 and an air outlet 2. The unit body 1, the generator 8 and the engine 9 are mounted on a moving carriage 10.

The moving carriage 10 is moved to a place where the fresh plants 11 are accumulated, and the cover 12 made of a vinyl sheet or the like covering the fresh plants 11 and the air suction port 5 are connected to the flexible suction duct.
The cover 12 and the air outlet 2 are connected by a flexible outlet duct 14.

Then, when the engine 9 drives the generator 8, the electricity generated by the generator 8 is supplied to the drive motor 15 of the blower 3 and the ozone generating means 6.

As a result, the air containing ethylene in the cover 12 is sucked into the unit main body 1 through the suction duct 13 and the air suction port 5, and flows from around the ozone generating means 6 to the ozone generating means 6. Ozone is generated in response to the irradiated ultraviolet rays, and ethylene is decomposed by this ozone.

The remaining ozone is decomposed in the process of passing through the ozone decomposing means 7. Next, this air is urged by the blower 3 and blown into the cover 12 from the air outlet 2 through the blowout duct 14.

When the fresh plant 11 is stored in a storage box of a warehouse or a truck, the suction duct 13 and the blowing duct 14 may be removed from the unit body 1.

[0016]

According to the present invention, the moving carriage is moved to a place where fresh plants are accumulated, and the electricity generated by driving the generator by the engine is supplied to the ozone generating means and the blower. Since the freshness preservation device can be operated by this, the freshness of the fresh plant during collection and delivery can be maintained.

If the duct for connecting the air intake port and the air outlet port to the cover for covering the fresh plant is detachably attached, the freshness of the fresh plant covered by the cover can be maintained.
