Description

Pressure Resistance Type Fumigation Facility for Fruit Sterilization

The present invention relates to a pressure-resistant fruit fumigation disinfection facility, and more particularly, to a fumigation disinfection facility for a pressure-resistant fruit, and more particularly, When the fumigation gas is exhausted, air of constant temperature and humidity is supplied to the inside of the fumigation booth while operating the exhaust fan, thereby preventing the discoloration and damage of the fruit due to the high temperature and high humidity and preventing the fumigation disinfection door The present invention relates to a pressure-resistant type fumigation disinfection facility which is configured to be hermetically closed and provided with a pit cover on the door so as to prevent gas from leaking to the outside when fumigation is disinfected, .

In case of importing or exporting grain and dried agricultural products, timber, fruit, vegetables, seeds, etc., the import and export quarantine disinfection treatment regulation, which is administered by the Agriculture, Forestry and Livestock Quarantine Headquarters, do.

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 fruit box 290 loaded on the pallet 280 is opened to form the opening 290-1, After wrapping the fruit box (290), fumigation is performed by spraying gaseous fumigant (hereinafter referred to as "fumigant gas") inside the tent.

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 fruit box 290 must be closely arranged in the fumigation booth 170 as shown in FIG.

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 ".

As shown in FIG. 4, the conventional fume disinfection apparatus includes a plurality of fumigation booths 170 each having a concrete base part at the bottom and having an airtight wall and a roof at the upper part thereof, A door 310 provided at one side of the fountain 170 for allowing the work vehicle loaded with the fruit box 290 to pass therethrough and allowing airtightness to be maintained; A burner type vaporizer 30 for heating and vaporizing the liquid chemical liquid supplied from the chemical liquid tank 10 and a vaporizer for vaporizing the fumigated gas vaporized in the vaporizer 30 from the fumigant booth 170 And an air supply line 90-1 for supplying air into the inside of the fumigation booth 170. The fumigation gas is supplied to the fumigation booth 170 through the fumigation gas supply line 50, And an exhaust line 110-1 for exhausting the exhaust gas Wherein the fumigant gas is supplied into the fumigant booth 170 after the pressure inside the fumigant booth 170 is reduced to negative pressure and the fumigant gas is supplied to the fumigant gas supply line 90-1 A plurality of fumigant gas spray nozzles 50-1 provided at the ends of the fumigant booths 170 are provided on one side of the fumigation booth 170 on the respective passages between the fruit boxes 290.

According to the above-described structure, since the inside of the fumigation booth 170 is formed into a negative pressure state and the fumigant gas is sprayed, the fumigant gas can be rapidly diffused even if the fruit boxes are closely arranged.

Accordingly, it is possible to shorten the time required for fumigation disinfection and to minimize the amount of the expensive chemical solution.

The conventional fume disinfection apparatus shown in FIG. 4 is disposed on the inner side of the fumigation booth 170 so that the fumigated gas sprayed from the fumigation gas spray nozzle 50-1 is discharged to the inside of the fumigation booth 170 A lower horizontal circulation fan 210 disposed on the bottom of the fumigation booth 170 to circulate the fumigation gas horizontally and a lower horizontal circulation fan 210 disposed on the opposite side of the vertical circulation fan 200, And a horizontal circulation fan 220 for circulating the fumigated gas in the horizontal direction.

The vertical circulation fan 200 is provided on a plurality of fumigant gas spray nozzles 50-1 provided on one side of the fumigation booth 170 and the lower horizontal circulation fan 210 is installed on a stacked fruit box (290). ≪ / RTI >

The horizontal circulation fan 220 is provided on the opposite side of the vertical circulation fan 200, and a plurality of vertical circulation fans 220 are provided for each passage between the stacked fruit boxes 290.

According to the above-described structure, the fumigant gas is sprayed from one side of the lower portion of the fumigation booth, and then the plurality of vertical circulation fans and the horizontal circulation fan are operated, so that the fumigant gas can be circulated smoothly even if the fruit boxes are arranged tightly in the fumigation booth.

However, when the present applicant constructed the fumigation disinfection apparatus shown in FIG. 4 and actually used it, it was found that when the fumigant gas is discharged to the outside after the fumigation is performed, the fruits are discolored by the high- .

When the fumigation gas is exhausted after the completion of the fumigation disinfection, the first control damper 90 is opened, the air supply fan 80 is operated, the second control damper 110 is opened, .

The fumigant gas in the fumigation booth 170 is exhausted to the outside of the facility through the exhaust line 110-1 and the exhaust treatment unit 130. [

4, although the air supplied to the air supply fan 80 is air inside the facility 100, the facility 100 itself is a huge warehouse (see FIG. 3) 100) is not significantly different from the temperature and humidity of the air outside the facility.

That is, the air supplied into the fumigation booth 170 through the air supply fan 80 in the fumigation disinfection apparatus shown in FIG. 4 is practically no different from the air outside the facility 100, that is, the atmosphere.

Accordingly, hot and humid air is supplied to the inside of the fumigating booth 170 in winter, and cold air is directly supplied to the inside of the fumigation booth 170 in the winter.

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 fruit box pallet 280 is arranged at 8 × 13 (see FIG. 4), it takes about one hour for the exhaustion of the fumigation gas to be completed. In this process, The quality of the product is deteriorated.

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 fruit box 290.

That is, at the time of fumigation disinfection, the fruit box 290 is not completely opened and disinfected. Instead, as shown in FIG. 2, the fruit box 290 having the opening 290-1 formed therein is inserted into the pallet 280, As shown in FIG. 3, disinfecting is performed in a state where a plurality of pallets 280 are loaded in the fumigation booth 170.

Accordingly, there is a problem that it is difficult for the fumigant gas to infiltrate into the fruits contained in the fruit box 290.

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 conventional fumigation booth 170 is not completely closed, the fumigation gas 170 flows out to the outside of the fumigation booth 170, so there is a limit to increase the pressure inside the fumigation booth 170.

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.

The conventional fruit or vegetable quality control apparatus shown in Fig. 1 comprises a partition wall 2 installed in the interior of the storage room 1 and arranged to stand in the interior of the storage room so as to partition the flow control room 4 and the flow path 3, A plurality of suction fans 8 installed on the partition 2 and a plurality of suction fans 8 arranged on the partition wall 2 such that one end thereof is provided on the upper part of the partition wall 2, And a cover member (9) covering an upper surface of the box and an opposite surface of the box on the side opposite to the partition wall (2), wherein a side surface of the box (6) partially closed by the cover member Is introduced into the central passage through the air vent holes 7 on both sides which are formed so as to smoothly perform the internal air circulation and then sucked toward the partition wall 2 by the suction fan 8, To the air ventilation port 7 side by an air circulation path It is.

However, the apparatus for managing the quality of fruits or vegetables shown in FIG. 1 is not for the fumigation disinfection apparatus of the present invention but for maintaining the quality of fruits or vegetables during storage.

Then, the first control valve 20 of the chemical liquid tank 10 is operated to supply the liquid fumigant to the burner-type vaporizer 30.

The second control valve 40 is operated to supply the fumigant gas through the fumigant gas supply line 50 after the liquid fumigant is vaporized in the gas state by the burner type vaporizer 30 to generate the fumigant gas.

Then, the gaseous fumigant gas is injected into the fumigation booth 170 through the fumigant gas injection nozzle 50-1.

The fumigant gas injected into the fumigation booth 170 through the injection nozzle 50-1 is diffused to the lower portion of the fumigation booth 170 by the operation of the vertical circulation fan 200 installed on the upper part thereof.

4, the fumigant gas is diffused to the left portion of the fumigation booth 170 by the operation of the lower horizontal circulating fan 210 provided on the bottom surface of the fumigation booth 170. As shown in FIG.

The fumigant gas is diffused to the right portion of the fumigation booth 170 by the horizontal circulation fan 220 installed in the vertical direction on the left side of the fumigation booth 170.

When it is determined that the fumigation disinfection is completed, the first control valve 20 for supplying the fumigant is closed and the operation of the vaporizer 30 is stopped.

Then, after the first control damper 90 is opened, the blowing fan 80 is operated and the second control damper 110 is opened, and then the exhaust fan 120 is operated.

Then, the harmful fumigant gas is purified by the exhaust treatment unit 130 provided on the exhaust line 110-1 and then discharged to the outside of the facility.

When the concentration of the harmful fumigation gas in the fumigation booth 170 becomes lower than the allowable reference value, the door 310 is opened and the working vehicle is introduced to transport the fruit box 290 to a predetermined place.

Next, the characteristic parts of the present invention will be described with reference to Figs. 5 to 13. Fig.

5 and 6, the pressure-resistant fruit fumigation disinfecting facility according to the first embodiment of the present invention includes a plurality of fumigation booths 170 provided inside the facility 100, and the fumigation booth 170 A chemical agent tank 10 provided outside the facility 100 and containing a fumigant for disinfecting fruit, and a liquid chemical agent supplied from the chemical agent tank 10, A fumigant gas supply line 50 for supplying the fumigated gas vaporized in the vaporizer 30 to the inside of the fumigation booth 170 and a fumigant gas supply line 50 for supplying fumigant gas to the facility 100, the exhaust fume disinfection system according to the present invention is characterized in that the front, rear, left and right side walls, the ceiling and the bottom of the fumigation booth 170 are all formed of a concrete wall C .

According to the present invention, the fumigation booth 170 serves as a kind of pressure vessel by the concrete wall C and the steel plate S.

With the above pressure-resistant structure, the fumigation booth 170 can be continuously injected with the fumigant gas without having to form the pressure of the fumigation booth 170 as a negative pressure before fumigation disinfection can be performed.

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.

However, according to the present invention, since the fumigation booth 170 itself is of a pressure-resistant type, it is not necessary to form the pressure inside the fumigation booth 170 to be negative (negative pressure) before the fumigation disinfection is performed, Can be increased.

That is, the fumigation booth 170 can inject fumigant gas regardless of the internal pressure to increase the pressure. Therefore, it is possible to perform the fumigation disinfection without regard to the kind of the fruit and the kind of the fumigant.

In particular, even in the case of fruits packed in vinyls such as bananas, the fumigant gas can be well penetrated into the interior of the fruit box.

In addition, fumigants such as ethyl formate, which are increased in volume by a pressure increase, can be used without limitation.

According to the present invention, since the door 310 of the fumigation booth 170 is constructed to be completely hermetically sealed (as will be described later), it is possible to prevent leaking of fumigant gas to the outside during fumigation disinfection.

The pressure-resistant fumigation booth according to the present invention is economically advantageous compared to the conventional sandwich panel fumigation booth, considering the shortening of the fumigation disinfection time and the reduction of the expensive drug, though the initial facility cost is increased.

As shown in FIG. 5, a pressure regulator 180 for regulating the pressure inside the fumigation booth 170 is provided outside the fumigation booth 170.

The pressure inside the fumigation booth 170 can be easily controlled by the pressure regulating device 180 according to the type of the fruit and the type of the fumigant.

Further, since the pressure-resistant fumigation booth according to the present invention has a structure for preventing leakage of fumigant gas, it is possible to easily adjust the concentration of the fumigant gas to meet the inspection standard, and to prevent excessive use of fumigant.

 The present invention further includes a constant temperature / humidity control unit 500 for supplying air of a predetermined temperature and humidity into the fumigation booth 170 when the fumigant gas is exhausted after the completion of the fumigation disinfection.

Accordingly, air having a predetermined temperature and humidity can be supplied into each of the fumigation booths 170 through the air supply fan 80.

It is preferable that the vaporizer 30 for heating the liquid chemical liquid to produce a gaseous fumigant is an electric heater vaporizer or a boiler vaporizer.

Conventional burner type carburettors have a high risk of fire, require a gas supply line and a burner for supplying combustion gas, and have to be separated from each other by using refractory bricks or the like, so that the structure is complicated.

However, if the electric heater type or the boiler type vaporizer is installed as in the present invention, the problems of the above-described conventional techniques can be solved.

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.

Accordingly, the door 310 and the sealing member 630 are completely separated from each other, and the door 310 is maintained in a vertical position.

When the driving motor 620 is rotated clockwise in this state, the door 310 integrated with the assembled rack 610 moves leftward.

According to the second embodiment of the present invention, a rack is provided on the door and the door is driven by a pinion, thereby greatly simplifying the door driving method.

Particularly, since the rack provided at the upper portion of the door moves along the axial direction of the pinion, and the shaft provided at the lower portion of the door also slides in the same direction while riding on the rotary roller, can do.

Further, since the second pusher provided on the wall side pushes the door toward the outside before sliding the door, the door and the sealing member can be easily separated from each other.

Further, since the guide member is provided on both sides of the pit, the door moving along the pit can be stably slid.

In other words, according to the door apparatus according to the second embodiment of the present invention, it is possible to easily slide the sliding door even in the case of a door having a heavy weight, and to easily close the door toward the wall side and to easily push the door toward the outside have.

Thus, breakage of the door driving device and the sealing member can be prevented.
