If a pest is found in the export-import plant, it is necessary to disinfect the fungus by disinfecting the fumigation, heat treatment, immersion of the chemical, etc., and carry out the customs procedure.
Of the above import and export plants, fruits such as orange, banana, and pineapple are generally sterilized with gaseous fumigants to kill pests (hereinafter, such fumigation is referred to as 'fumigation').
Since the fumigant used for the fumigant disinfection contains harmful toxic substances to the human body, the fumigant disinfection must satisfy the requirements stipulated in the disinfection treatment standard.
For example, the disinfection of the above-mentioned fumigants should be carried out in the presence of an engineer with a certain qualification requirement, and there are also limitations on the processing temperature of the fumigant disinfection, the processing time, and the amount of fumigant used.
In addition, fumigating workers should wear protective equipment such as respirators, protective clothing, etc.
However, according to the conventional fumigation disinfection method, as shown in FIG. 2, a part of the
The fumigation disinfection method has a problem in that it takes a long time to install a tent and a vinyl sheet, resulting in an increase in labor costs.
In addition, since the fumigant gas is heavier than air and sinks to the floor when fumigation is disinfected, there is a high possibility that the fumigant gas is discharged to the outside of the tent on the floor surface during fumigation.
In addition, since it is difficult to accurately grasp the concentration of the harmful fume gas to be injected into the tent, the pest is not killed by the use of the fumigant gas or the fumigant gas is excessively used.
Further, when the tent is dismantled after the disinfection of the fumigant, harmful fumigant gas poses a threat to the health of the operator.
As a method for solving the above-mentioned conventional problems, the present applicant has filed an application for a "device for disinfecting ornamental fumigation using an enclosed facility and an external control device" of Application No. 10-2013-143619.
The above-described fume disinfection apparatus can prevent fume disinfection inside the enclosed facility and direct exposure to the harmful fumigation gas by controlling the fumigation disinfection outside the facility.
However, the conventional fume disinfection apparatus has a problem that the fumigant gas injection nozzles are disposed on the upper part of the facility, and the fumigant gas is not circulated evenly inside the facility when the fruit or vegetable boxes are closely arranged.
In order to reduce the amount of the expensive medicines, the
However, according to the fumigation disinfecting apparatus, the fumigant gas is not supplied smoothly between the fruit boxes, so that the effect of fumigation disinfection is deteriorated.
In order to solve this problem, it is possible to enlarge the interval between the fruit boxes, but in this case, the number of fruit boxes to be loaded in the fumigation booth is reduced, and the fumigation disinfection time is lengthened and the amount of high-
In order to solve such a problem, the present applicant has filed a Korean Patent Application No. 2014-17553 as a "apparatus for sterilizing or purifying fuels of greenhouse using fixed facilities ".

In particular, when hot and humid air comes into contact with fruits directly in summer, fruits such as bananas become easily discolored and the merchantability is deteriorated.
In the case of the fumigant booth in which the
In addition, in the conventional fumigation booth in which the wall is formed of the sandwich panel, in order to spread the fumigant gas evenly, the pressure inside the fumigation booth is lowered to form a negative pressure (negative pressure) state before the fumigation gas is injected, .
As a result, it takes a long time to disinfect fumigation.
If fumigation gas is injected in the fumigation booth of the sandwich panel without forming the internal pressure as negative pressure, the fumigated gas does not penetrate well into the fruit contained in the
That is, at the time of fumigation disinfection, the
Accordingly, there is a problem that it is difficult for the fumigant gas to infiltrate into the fruits contained in the
In order to solve this problem, there is a method of increasing the pressure of the fumigant gas. The conventional fumigation booth formed of the sandwich panel can not withstand this pressure.
In addition, since the
Accordingly, there is a problem that the time required for fumigation disinfection is delayed, resulting in an increase in the amount of high-priced medicines used.
In addition, recently, ethyl formate, which is widely used for fumigation of banana, has a feature of increasing the volume when the pressure is increased, so that it is difficult to increase the pressure inside the fumigation booth made of sandwich panels .
In addition, the conventional fumigation booth has a problem that it is difficult to control the concentration of the fumigated gas injected into the fumigation booth due to leakage of the fumigation gas.
Meanwhile, Korean Utility Model Application No. 20-2010-0012752 discloses a device for controlling the quality of organs and fruits.

According to the pressure-resistant fumigation booth according to the present invention, it is possible to withstand the pressure of 2,000 to 3,000 mmAq, so that fumigation can be performed without regard to kinds of fruits or fumigants (for reference, , The internal pressure should be increased to 50 mmAq and the pressure after 5 minutes should be 5 mmAq or more).
Conventional fumigation booths formed with sandwich panels are not completely enclosed and can not increase the internal pressure beyond a certain level.
For this reason, in the conventional fumigation disinfection facility, the internal pressure is set at a negative pressure (negative pressure) before the fumigation disinfection is performed, and then the fumigation gas is injected.

According to the conventional door device in which the pits P are formed at the doorway, it is difficult for the work vehicle such as a forklift to pass through the doorway pit. Therefore, a separate pit lid must be laid on the pit P to enter the inside of the facility.
When the work is completed and the door is closed, the door must be closed after removing the pit cover.
However, according to the door apparatus of the present invention, when the door is opened, the door cover automatically covers the entrance pit, so that the driver of the vehicle can quickly enter the inside of the fumigation booth.
According to the pressure-resistant fruit fumigation disinfection facility of the present invention, as shown in FIG. 6, the side wall and the ceiling of the fumigation booth are all made of a concrete wall C, and the iron plate S is hermetically provided on the inside thereof.
Further, since the door device is constructed in a completely closed type, the fumigation booth itself serves as a kind of pressure-resistant vessel.
Accordingly, since it is not necessary to form the pressure of the fumigation booth as negative pressure (negative pressure) before the conventional fumigation disinfection as in the prior art, the time required for fumigation disinfection can be drastically shortened and the use amount of the expensive medicine can be reduced .
The pressure-resistant fumigation disinfection facility according to the present invention can withstand a high pressure of 2,000 to 3,000 mmAq, so that it can be easily fumigated without regard to kinds of fruits and fumigants.
In other words, since the pressure inside the fumigation booth can be maintained at a high pressure, fumed fruits such as a banana can be easily fumigated.
Also, fumigants such as ethyl formate, which increase in volume by increasing pressure, can be used without limitation.
Conventional fumigation booths formed by sandwich panels are not completely hermetically sealed, so that it is difficult to maintain the pressure inside them at a high pressure.
However, according to the present invention, since the wall and the ceiling are made of a pressure-resistant type and the door device is constructed in a completely hermetically sealed type, the pressure inside the fumigation booth can be maintained at a high pressure.
In addition, since there is no leaking of the fumigant gas, even if the size of the fumigation booth is large, it is possible to quickly reach the predetermined pressure.
As a result, it is possible to shorten the time required for fumigation disinfection and reduce the amount of high-price medicine.
In addition, since the fumigation disinfection can be performed by adjusting the pressure and the concentration of the fumigant gas by the pressure regulating device installed on the outside of the fumigation booth, the fumigation disinfection operation becomes very simple.
In addition, since the structure prevents the leakage of the fumigant gas by the closed door device, the concentration of the fumigant gas injected into the fumigant booth can be easily controlled and the excessive use of the fumigant can be prevented.
In addition, when the fumigant gas is exhausted after completing the fumigation, the air having a predetermined temperature and humidity is supplied to the inside of the fumigation booth by the constant temperature / humidity control unit, so that the hot, It is possible to prevent discoloration or damage.
