トラップ13を順次作動させる。The operation of the container for transporting fresh plants constructed as described above will be explained below. First, a plurality of vacuum containers 1 and transport containers 9 are arranged in the necessary number at a harvesting area for fresh plants, and when vegetables, fruits, etc. are harvested, they are packed in boxes and placed in the transport containers. When the car 2 equipped with the vacuum cooling device 3 visits the vacuum container 1, the vacuum cooling device 3 is connected to the exhaust port 5 of the vacuum container 1, and the transportation container 9 containing fresh plants is transferred to the vacuum container 1. 1, and the vacuum pump 15 and cold trap 13 are operated in sequence.

ンテナ9を常温或いは低温で輸送する。[0008] As a result, the inside of the vacuum container 1 and the container 9 are evacuated, and the ethylene gas that ages and ripens the fresh plants is eliminated, and the moisture from the fresh plants evaporates, lowering the temperature and vacuum cooling. . After this vacuum cooling, a mixed gas of carbon dioxide gas and nitrogen gas at an arbitrary mixing ratio is introduced into the vacuum container 1 from the gas inlet 7 to bring it to atmospheric pressure, and the container 9 is transported at room temperature or low temperature.

った。During this transportation, by the action of the gas-selective permeable membrane 20 provided at the vent 21 of the container 9, carbon dioxide gas inside the container 9 is exhausted and oxygen from the outside is introduced. Since the concentration of carbon dioxide gas is kept constant, fresh plants can be transported to the market while maintaining their freshness without causing carbon dioxide damage during transportation.

蒸気透過性が悪い。However, in the above-described configuration and method, since the shipping container 9 does not have a cooling device, a separate low-temperature transport vehicle is required for low-temperature transport. Further, the shipping container 9 is a closed system, and the gas selective permeable membrane 20 provided in the vent 21 keeps the mixed gas of carbon dioxide gas and nitrogen gas introduced into the container 9 at a given mixing ratio constant.

In addition, due to the high humidity inside the container 9, various bacteria tend to grow and become unsanitary and smelly. Furthermore, since the shipping container 9 is a pressure-resistant container, it is very heavy and difficult to handle. Conventionally proposed containers and transportation methods for transporting fresh plants have had the above-mentioned problems.

Keep the humidity inside the container suitable for vegetables,
In addition, ozone prevents the growth of bacteria, deodorizes them, and decomposes ethylene gas emitted from fresh plants, thereby creating a container for transporting fresh plants such as vegetables and fruits without deteriorating their quality. The purpose is to provide.

。Furthermore, although the inner box 25 has a sealed structure, as mentioned above, moisture exceeding the saturated humidity escapes from the membrane module 27 due to the water vapor partial pressure difference inside and outside the inner box 25.
Condensed water does not adhere to the top surface of the inner box 25, and damage to soft fresh plants such as spinach and asparagus due to stuffiness caused by dripping of condensed water that occurs when the container is simply sealed can be prevented. Furthermore, the shipping container 23
has a double structure and can indirectly cool the fresh plants A without the cold air directly entering the inner box 25.
It can be transported in a fresh state without being dried.

Ethylene gas discharged from vegetables, fruits, flowers) permeates through the moisture permeable membrane 27a and enters the ethylene decomposition device 33.
The ethylene adsorbent 44 adsorbs the ethylene adsorbent. The ethylene gas adsorbed here is efficiently decomposed by the air ozonized by the ozone generating electrode 36 on the windward side. Therefore, the ethylene adsorbent 44 is constantly regenerated and does not need to be replaced.

It is safe because people are not exposed to ozone when the door 30 of the container is opened. In addition, due to the action of ozone, container 2
The air inside 3 is sterilized and deodorized.

The fresh plants A stored in the container are kept at moderately high humidity and low temperature without becoming stuffy, and ethylene gas, which has aging and ripening effects, is efficiently decomposed using an ethylene adsorbent and ozone. Category A can be stored and transported in a fresh state.

輸送することができる。Therefore, the shipping container 23 does not require a special truck for low-temperature transportation, unlike the conventionally proposed transportation method using the shipping container 9, and can be easily transported by an ordinary truck. Since a vacuum container 1 and a vacuum cooling device 3 are not required, transportation can be carried out at low cost. the current,
In many production areas of fresh plants that require pre-cooling (asparagus, lettuce, spinach, etc.), vacuum pre-cooling equipment or differential pressure pre-cooling equipment is installed in the production area, and fresh plants after pre-cooling are transported to the transport container 23. Freshness can be maintained by transporting the food.

ムレがほとんど生じない。The moisture-permeable membrane 27a allows water vapor to pass through it well, whereas the gas-selective permeable membrane 20 of the conventional example has a CA
Due to the use of a membrane material (such as polyethylene) for the storage atmosphere, the water vapor permeability is generally lower than that of the moisture permeable membrane 27a.
It's much worse than that. Therefore, in the conventional example, the humidity is too high and stuffiness occurs, but in the shipping container 23, stuffiness hardly occurs.
