Description

  In the present invention, a biogas (phytoncide gas) of an aromatic substance extracted from a bamboo leaf is adsorbed and held in a powdery or small block of zeolite, and the zeolite adsorbed with the biogas is loaded when storing fruits and vegetables. It is related with the improvement about the manufacturing method and manufacturing apparatus of the freshness-keeping agent used so that the freshness of fruit and vegetables may be kept.

  Gaseous aromatic substances extracted by supplying steam from pine and cedar leaves are adsorbed to zeolite (zeolite), and the adsorbent zeolite is used to store and preserve fruits and vegetables. In this case, means used as a freshness-preserving agent is known from Japanese Patent Publication No. 7-25647.

  The freshness-preserving agent used in this means is a gaseous fragrance that is extracted from the steamer with the steam by supplying steam generated by the boiler to the leaves of the conifers charged in the steamer. (Biogas) is guided to the gas-liquid separator and cooled to remove the mixed water vapor and separate only into the biogas, and this is supplied into the zeolite tank in which the zeolite is charged. Therefore, it is a freshness-preserving agent produced by adsorbing to the zeolite in the tank.

  The freshness-preserving agent obtained by this means is effective in maintaining the freshness of fruits and vegetables, but there is a problem that the freshness-retaining effect obtained varies with the product of the freshness-preserving agent produced. . This means that there is variation in the amount of biogas adsorbed on the zeolite of the product.

In addition, there is a problem that the biogas fed to the zeolite tank extracted and fed to the zeolite tank has a large adsorption loss to the zeolite and the production efficiency of the freshness-preserving agent is poor. This is because, if an exhaust port is provided in the zeolite tank so that the biogas extracted and supplied to the zeolite tank is continuously contacted with the zeolite in the tank, the zeolite adsorbed with the biogas In addition, when biogas that is continuously fed comes into contact, a part of the biogas is released from the exhaust port and scattered, increasing the loss and eliminating the exhaust port. If the zeolite tank is sealed, the biogas extracted and fed into the zeolite tank will flow back to the steamer when the gas pressure in the zeolite tank increases. This hinders the supply of biogas to the zeolite tank, causes external scattering from the steamer, and reduces the efficiency of biogas adsorption on zeolite. According to the to become that allow.

Let them collect.

  This bag-like body 5 is formed in a state in which the peripheral wall is folded and flattened from the state where the peripheral wall is folded flat, and the peripheral wall is opened by the gas pressure of the injected phytoncide gas. It is removed from the connection port 30, pulled out by the vacuum pump P, pressurized and packed in the cylinder B by the compressor C, transferred to the cylinder and stored.

Next, the process of adjusting the zeolite stone particles to adsorb the phytoncide gas will be described.
Zeolite ore that has been baked to about 400 ° C and formed into small granules with a diameter of about 5 mm is sieved and carefully selected to remove stone dust and debris and weighed to a predetermined unit weight (about 50 g). Zeolite ore is remarkably improved in adsorption function by firing. As for the granulation of the zeolite ore, the smaller the diameter, the better, but about 5 mm is desirable for handling.

  A weighed unit weight of zeolite stone is loaded into a mesh bag. The mesh of the mesh bag should be such that the filled zeolite stone particles do not flow out and be as breathable as possible. A large number of zeolites are prepared as packed in the mesh bag.

  Next, the process of adsorbing phytoncide gas to this zeolite will be described.

  The mesh bags packed with zeolite stone particles adjusted as described above are collected into a predetermined number of bundles, and the bundles are packed in a pressure cooker (vacuum cooker) 7 prepared separately and stacked in an appropriate number of stages. The kettle 7 is sealed.

  Next, the inside of the pressure cooker 7 is evacuated to a reduced pressure state by the vacuum pump P. This vacuuming lasts for more than 40 minutes, so that all of the zeolite adsorption surface is exposed to a vacuum degassed and depressurized atmosphere.

  When this predetermined period of time is over, phytoncide gas is supplied to the pressure cooker 7. In this supply, the phytoncide gas extracted from the bamboo leaf and stored in the cylinder is transferred from the cylinder B to the folded bag 5 and the mouth 50 of the transferred bag 5 is transferred. Is connected to a connection port 70 provided in the pressure cooker 7, and a valve provided in the connection port 70 is opened to allow the bag-like body 5 to communicate with the pressure cooker 7. The bag-like body 5 connected to the connection port 70 of the pressure cooker 7 may be directly connected to the bag-like body 5 before the collected gas is transferred to the cylinder B.

  As a result, the phytoncide gas in the bag-like body 5 is sucked in from the negative pressure in the pressure cooker 7 and is sent into the kettle 7, and the fed-in gas is the zeolite stone that is filled in the pressure cooker 7. It is adsorbed in contact with the grains.

  In order to sufficiently absorb the phytoncide gas to the zeolite stone particles, the step of connecting the bag-like body 5 filled with the phytoncide gas to the pressure kettle is continued for about 1 hour, and slowly And take sufficient time to adsorb.

  When this adsorption process is completed, the pressure cooker is opened, and the zeolite stone particles are quickly taken out for each mesh bag, and each bundled mesh bag is inserted into an airtight gas barrier bag, and the mouth of the gas barrier bag is sealed with a sealer. Seal and seal to make a product of freshness-preserving agent.

  When using this freshness-keeping agent, for example, when the producer of fruits and vegetables is used to hold the freshness of the boxed fruits when shipping the boxed fruits, etc. Open the gas barrier bag mentioned above, take out the mesh bag filled with zeolite stone particles adsorbed with phytoncide gas, put the mesh bag into a box filled with fruits, and seal the outer periphery of the box with airtightness. Wrap with strong wrapping paper and use to seal.
