Abstract

PURPOSE:To enable maintaining freshness in the case of a long-time transportation by providing a means for controlling a gas environmental condition detected by oxygen and carbon dioxide content detectors and nitrogen and air feeders regulated by the control means. CONSTITUTION:A product, which has been stored in a refrigerator, is carried in a container and nitrogen gas and air are respectively supplied from a nitrogen feeder 1 and air feeder 2 until oxygen and carbon dioxide contents in the container reach those fit for storing the product, while the oxygen and carbon dioxide contents in the container are monitored by oxygen and carbon dioxide content detectors 4 and 5. When the oxygen content decreases and a predetermined carbon dioxide content is exceeded during the storage and transportation, nitrogen is supplied and carbon dioxide is discharged to reach the predetermined content. When the oxygen content falls below a predetermined content, the supply of nitrogen is interrupted and air is supplied to maintain the predetermined oxygen content. When the gas environment is regulated by a gas environmental control means 6 to that fittest for the storage, the respiration of the product is suppressed also by the gas environment so that the product can be transported for a long period of time as it maintains its freshness.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a freshness-keeping container suitable for transporting products such as vegetables, fruits, and flower petals, and a method for transporting products using the container.

[Prior Art] Conventionally, as a method of transporting vegetables, fruits, flower petals, etc., these products were packed in cardboard or plastic boxes and transported by truck, freight car, etc. However, with this method, it is impossible to maintain the freshness of the product, and therefore the range of transportation is limited. Recently, products such as vegetables, fruits, and flower petals are packed in cardboard or plastic boxes and stored at low temperatures in refrigerated or frozen containers, basically suppressing their physiological effects to maintain their freshness. Transport began to take place over greater distances.

Products such as vegetables, fruits, and flower petals have physiological effects even after they are harvested, and in order to maintain appropriate freshness, it is necessary to understand the physiological effects of each product, especially after harvest. be. For example, if tomatoes are harvested at full ripeness, they will become overripe, red in color, soft in flesh, and less marketable. Freshness preservation here is achieved by preventing overripening. On the other hand, cucumbers, broccoli, asparagus, bamboo shoots, etc. are harvested before they are fully ripe, and continue to grow even after harvest. The preservation of freshness here is achieved by suppressing ripening, flowering, growth, etc., and it is difficult to control these in a similar manner. However, one effective method for suppressing the physiological effects of these products after harvest is a method of suppressing the respiratory effects of the products.

This is achieved by providing an air supply device and an optional carbon dioxide gas supply device.

The effective gas environment for maintaining the freshness of products is not uniquely determined because it depends on the type of product, but it is recommended to set the oxygen concentration to 0.5 to 15% and the carbon dioxide concentration to 1 to 15%. is effective.

When the oxygen concentration is higher than 15%, the effect of respiratory depression is small, and in hypoxic conditions lower than 0.5%, the product enters anaerobic respiration, which does not require oxygen, resulting in the release of alcohol, acetaldehyde, and acetic acid. This is undesirable because it will result in the generation of such substances, which will actually degrade the quality. Carbon dioxide gas not only lowers the partial pressure of oxygen and assists in suppressing respiration, but also has the function of suppressing the aging of plants, but at a concentration of 1%.
No such suppressive effect was observed at lower concentrations, and 15
If the concentration is higher than %, it is not preferable because it causes hypercarbonic gas damage such as internal browning in the product.

In order to adjust the oxygen concentration and carbon dioxide concentration in a container, it is usually done by supplying or stopping the supply of nitrogen gas or air using a nitrogen supply device or an air supply device. Adjustment can also be made by installing a supply device and supplying and stopping carbon dioxide gas from the device. These gas environmental conditions are controlled by the control means in accordance with the detection results of the oxygen concentration detector and the carbon dioxide concentration detector.

Since the nitrogen gas generated by the PSA device is in a dry state, it is used after being humidified by a conventional method. The PSA device is not particularly limited, but since it is attached to a container, its size is naturally limited, and a device with a nitrogen supply rate of 50 to 4000 J per hour can be used.

The products stored in the refrigerator are loaded into a container equipped with the PSA device, and then the oxygen concentration and carbon dioxide concentration inside the container are monitored by the oxygen concentration detector 4 and the carbon dioxide concentration detector 5. Nitrogen gas is supplied from the PSA device, air from the air supply device 2, or carbon dioxide gas from the carbon dioxide gas supply device 7 until the internal oxygen concentration and carbon dioxide concentration reach concentrations suitable for storing the product. At this time, if the capacity of the container is large and it takes a long time to replace the gas, if necessary, after bringing in the product, use another large nitrogen gas supply device and carbon dioxide gas supply device, such as a collective cylinder, to supply nitrogen gas and By supplying carbon dioxide gas, the time required to create a predetermined gas environment inside the refrigerator (pulldown) can be shortened. Further, when carbon dioxide gas generated by the respiration of the product is used as carbon dioxide gas, it is not necessary to provide a carbon dioxide gas supply device. Afterwards, during storage and transportation, if the oxygen concentration decreases and the carbon dioxide concentration increases and exceeds the prescribed carbon dioxide concentration, the PSA device is operated to supply nitrogen and exhaust carbon dioxide to reach the prescribed carbon dioxide concentration. Let it be the concentration. Furthermore, when the oxygen concentration falls below a predetermined concentration, nitrogen from the PSA device is stopped and air is supplied to maintain the predetermined oxygen concentration. In this way, the gas environment control means provided in the container adjusts the gas environment to be optimal for storing the product.
