Description

  The present invention provides a device in a container in order to maintain the freshness of the fruit and vegetables packed in the container when the fruit and vegetables are stored or shipped in a container for storage or shipment. The present invention relates to an improvement of a freshness maintaining apparatus.

  When producers pack and store fruits and vegetables in storage or shipping containers, such as phytoncide gas extracted from the leaves of conifers such as birch leaves that have a freshness-keeping function Biogas released from zeolite powder by placing a freshness-keeping agent made by adsorbing aromatic biogas onto zeolite powder at a position next to fruits and vegetables in the container Thus, the means for maintaining the freshness of the boxed fruits and vegetables has been conventionally performed.

  However, this means that the effect of maintaining the freshness is remarkable and that the effect is not so much, and there are cases where molds and spoilage occur in the fruit and vegetables shipped in a box, and the effect is surely obtained. There is a problem that cannot be expected.

  In particular, when the container is packaged under high-humidity environmental conditions that cause condensation on the surface of fruits and vegetables, the freshness-preserving agent charged in the container will hardly function. First, mold and rot occur frequently.

  Conversely, in a dry environment where the humidity is extremely low, the inside of the container is in a dry state, and when a freshness-preserving agent is inserted and used together with fruits and vegetables, the effect of keeping freshness does not increase, The surface of fruits and vegetables dries and the quality is lowered.

  This means that the freshness-preserving agent is placed in a container packed with fruits and vegetables so that the freshness of the packed fruits and vegetables can be maintained. If the atmosphere is not adjusted and maintained at an appropriate humidity, the effect of maintaining the freshness cannot be surely obtained.

  The fruits and vegetables stuffed in the box are alive and living, and therefore, the fresh and fresh state of the fruit and vegetables are kept by the freshness-preserving agent. The environment inside becomes dry or changes to a wet state.

  Therefore, in order to obtain the effect of maintaining the freshness by loading this freshness-keeping agent in the box in which fruits and vegetables are stuffed, the inside atmosphere and environment in the box are dried. When equipped, a humidifier that releases moisture and raises humidity and a dehumidifier that absorbs moisture and lowers humidity when humidity rises are equipped, It is necessary to adjust the atmosphere / environment in the box to humidity and dryness adapted to the daily reactions and functions of the fruits and vegetables packed in the box.

  However, this container for storage or shipping is used in a disposable state, and it is costly to equip it with a humidifier and dehumidifier because it is loaded with a freshness-preserving agent. There is another problem that is too burdensome and unrealistic.

In addition, this means is that the freshness-preserving agent is a gaseous aromatic substance extracted from the leaves of conifers such as birch leaves adsorbed on zeolite, and its diffusion / release from the zeolite that is the adsorption / support is quick. There is a problem that the function of maintaining freshness will soon be lost due to scattering.

  The problem to be solved by the present invention is that the fruit or vegetable to be shipped is stored in a container for storage or shipping so that it can be kept fresh during storage or shipping. In the boxed state, the environment inside the container was adjusted to and maintained in a state adapted to the living reactions and functions of fruits and vegetables, and loaded inside as a freshness-keeping agent, and was adsorbed on zeolite. A freshness maintaining device for maintaining the function of maintaining the freshness by phytoncide gas can be configured as a state having both a humidifier and a dehumidifier with little cost burden.

And in this invention, as means for solving this problem,
A container (1) in which fruits and vegetables are packed and stored or shipped and formed into a square bag shape that can be inserted into the container (1) by an airtight sheet, and dropped into the container (1). Place the square bag (2) on the bottom of the square bag (2) with the floor covering (3) with multiple newspapers to be laid, and the floor covering (3). Between the cover (5) with a plurality of newspapers placed on the fruit and vegetables (4) to be stuffed and between the lower surface side of the cover (5) and the upper surface side of the stuffed fruits and vegetables (4) The freshness-keeping agent (6) in which the biogas placed and placed on the zeolite stone particles is adsorbed on the zeolite stone particles and filled in the mesh bag, and the band (7) that closes and closes the mouth (20) of the square bag (2) ) And a freshness maintaining device for containers for storing or shipping fruits and vegetables.
Is to raise.

  The freshness maintaining device for containers for storing or shipping fruits and vegetables according to the present invention comprises a floor covering 3 and a cover 5 in which a plurality of newspapers to be installed in a square bag 2 are stacked. Newspaper is made of pulp material that is not exposed to water, and has good moisture absorption and release characteristics. If the atmosphere in the square bag 2 is excessively humid, it absorbs moisture. It acts as a dehumidifier that can function as a humidifier that releases moisture when the humidity drops and becomes dry, and the atmosphere of the inner cavity of the square bag 2 The humidity and dryness conditions are adjusted to the state of life and function, and are kept in that state, so the freshness-retaining agent loaded together with fruits and vegetables will function effectively. , Fresh fruits and vegetables I would like to hold on.

  And the freshness maintenance agent 6 which made the biogas adsorb | suck to the zeolite stone particle | grains was mounted on the upper surface of the stuffed fruit and vegetables, when the biogas was a gas heavier than air and was released from the zeolite. Since it begins to sink from the position and spread throughout the entire area, the effect of maintaining the freshness is fully exhibited.

  In addition, when the filling of fruits and vegetables and loading of the freshness-preserving agent into the predetermined position is completed, the opening of the square bag is connected to a vacuum pump, the air in the square bag is degassed, the opening is closed, By binding with a string or rubber band, the biogas of phytoncide gas adsorbed on the zeolite stone particles of the freshness-retaining agent is replaced with ethylene gas generated from fruits and vegetables, By being released, biogas will be released from the zeolite stone as much as ethylene gas is generated, so as to effectively suppress aging and deterioration of fruits and vegetables And the effect of maintaining freshness is improved.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.
