っている。(Prior art) Conventionally, when importing fruits such as papaya from overseas, fumigation treatment is required to prevent pests and pests from entering the fruit.
Fumigation is usually carried out by gas treatment using methyl bromide, aluminum chloride, etc. However, with this method, there is a problem that fumigants such as methyl bromide remain in the fruit, so recently steam at around 40°C is introduced into the container containing the fruit, etc. to kill pests and their eggs. I am doing it.
(発明が解決しようとする課題)
前記の高温水蒸気で燻蒸を行なう場合、果実等の品質が
劣化し、蒸気によって濡れるため切り口からいたみが生
ずる問題があった。(Problems to be Solved by the Invention) When fumigating with the above-mentioned high-temperature steam, there is a problem in that the quality of fruits etc. deteriorates and spoilage occurs from the cut ends because they become wet with the steam.

続したもので構成するようにした。(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, the atmosphere in which fruits and other plants are placed is first made into a vacuum state, and then high-temperature steam is introduced to maintain the atmosphere at atmospheric pressure for a certain period of time. After that, the moisture is removed and the plants are vacuum-cooled again. To carry out this method, a fumigation device is installed in an airtight container containing fruits and other plants to generate high-temperature steam. It consists of a tank, a blower, a cold trap, and a vacuum pump connected to each other.

入したのち植物類を気密容器から取出す。(Function) First, the inside of an airtight container containing plants such as fruits is brought to a vacuum state of, for example, about 5 Torr using a vacuum pump. Then, for example, about 4
Fumigation is performed by introducing high-temperature steam at 0°C until it reaches atmospheric pressure, and maintaining that state while operating a blower for a certain period of time until the pests and their eggs die. Thereafter, the introduction of high-temperature steam is stopped, and the high-temperature steam in the container is rapidly removed by a vacuum pump via a cold trap. By quickly removing the high-temperature water vapor attached to the plants, the latent heat of vaporization is taken away from the plants, and the plants are rapidly cooled in vacuum, and the cut ends are dried, preventing a decline in quality. . Ethylene, which promotes aging and ripening of plants, is also removed from the inside of plants through this vacuum cooling. When the temperature of the plants reaches a predetermined temperature, the vacuum cooling is stopped, the atmosphere is introduced, and the plants are removed from the airtight container.

で安価に製作出来る等の効果がある。(Effects of the Invention) As described above, when using the method of the present invention, the atmosphere of plants is evacuated and then a high-temperature steam atmosphere is created, so the steam penetrates into the inside of the plants and fumigation can be performed quickly. Because the time of exposure to high-temperature steam is shortened, there is less deterioration in quality, and by fumigating in a vacuum, there is less risk of bacteria entering from the outside air.Then, the product is rapidly cooled by vacuum cooling, so there is no damage caused by temperature. As the amount decreases, the cut ends become dry and the damage from the cut ends disappears.
Effects such as being able to efficiently remove ethylene from the inside of plants, preventing aging and ripening of plants and making them last longer can be obtained. Furthermore, when using the apparatus of the present invention, the above method can be carried out by appropriately operating a high-temperature steam generation tank connected to an airtight container containing plants, a blower, a cold trap, and a vacuum pump, and its configuration is relatively It has the advantage of being easy and inexpensive to manufacture.
