Field of the Invention The present invention relates to the preservation and distribution of fresh products, such as fruits and vegetables, which are stored for a long period of time while maintaining a high fresh state, and the shipping time is adjusted from demand and supply. .

[0002]

2. Description of the Related Art Fresh commodities such as fruit and vegetables are harvested based on their growth and ripeness as evaluation criteria, and are collected and sorted by agricultural cooperatives. Then they are packed in a case and immediately shipped to supermarkets and other retail stores or fruits and vegetables market by truck. Generally, the time from harvesting to arranging in a store is at most about three days. Japanese Patent Publication No. Hei 7-117076 discloses a technique relating to such an automatic computerized wholesale auction system using a futures communication bidding for fresh and life products. This system will be described with reference to a system configuration diagram of FIG. 10 and a flowchart of FIG. In FIG. 11, reference numeral 111 denotes an input / output device modem 112, a fax adapter 113, and an OCR.

[0005]

As described above, even when a farmer or an agricultural cooperative tries to store fresh products in a normal refrigerator, the freshness quickly deteriorates, the storage period is short, and the shipping period cannot be freely selected. Even if the automatic computerized wholesale system using data communication lines is adopted as described above, the freshness of perishables is maintained for at most a few days. Even if it is not possible to maintain freshness for a long time,
There was a problem that it was far from stabilizing prices. In other words, there is a problem that the price of fresh products is simply determined by the current market price, and the profit of the producer is affected by the harvest time, and stable management cannot be performed. Also, computerization is a technology for extending the conventional wholesale market, and it does not provide a measure for fresh products when there is a large amount of collection, that is, when there is a harvest, assuming the existence of sellers and buyers. However, there was a problem that this system would not work if there were no items for sale. In addition, there is a problem that it is difficult to deal with the loss of commodities because the consumption side of fresh produce is also affected by trends such as seasonal feelings and advertisements. On the other hand, fresh produce such as fruits and vegetables is maintained at a low temperature as a method for maintaining high freshness, or a negative ion gas or a mixture of negative ions and low-concentration ozone gas as disclosed in JP-A-10-295344. A technique for suppressing the growth of microorganisms by using a gas is known. In recent studies, for example, it has been reported that the aging phenomenon of fruits is affected not only by ethylene but also by water supply. However, there is a problem that there is no technique for practically utilizing these effects.

[0006] The present invention solves the above-mentioned problems, and relates to a technique for maintaining the freshness of a produced fresh product and preventing the loss of the product, thereby stably distributing the product.
Further, the present invention proposes a fresh product preservation and distribution system in which many consumers in many regions can obtain fresh products of various seasons and in different amounts depending on the region at appropriate prices. .

In FIG. 2, reference numeral 38 denotes a cool air supply device for circulating air cooled inside the refrigerator 1, and 31 denotes a connection terminal and an open / close switch of the electric wiring 34, a connection portion of the water distribution pipe, and a water distribution pipe 35 which are attached to each container type refrigerator 15.
A control box having a valve device for turning on and off the flow of water, 32 is a power board to which a wiring 34 for supplying electricity is connected, 33 is a water supply tank to which a water distribution pipe 35 for supplying water is connected, and 36 is inside the refrigerator 1 The container-type storage 15 transported by the cooler 27 on the container-type storage 15 stacked and accommodated therein is electrically connected to the electric wiring 34 by being installed at a predetermined position on the refrigerator shelf 36 by a crane (not shown). A water supply pipe 35 for water supply is connected, and generation of ozone and negative ions by power supply and humidification by water supply are performed by a control device in a control box. The shelves 36 are provided with a ventilation space so that air can be sufficiently circulated in the refrigerator 1 so that cool air circulates in the refrigerator 1 and indirectly cools the inside of the refrigerator 1 through the wall surface of the container type storage. It is a shelf provided with. In this way, the fresh product is stored in a container provided with an opening and closing door, and is preserved while maintaining freshness.

FIG. 3 shows a description of the configuration schematically shown in FIG. 2 is a panel forming the wall surface of the refrigerator 4 inside the refrigerator 1, 9
Is a temperature sensor, 10 is a negative ion / ozone generator, 11
Is an ozone concentration control device, 13 is a humidity sensor, and 14 is a humidifier. The cool air supply device 38 includes a cool air fan 8 that circulates through the refrigerator 1 and a heat exchanger 7 of the refrigerator 6. The refrigerator that generates cold heat is disposed outside the compressor, and has a compressor, condensed gas, and an expansion valve. And a heat exchanger 7 serving as an evaporator in the refrigerator, and a cool air fan 8 for blowing air to the heat exchanger and circulating air as indicated by arrows. Reference numeral 5 denotes an object to be stored stored in the storage box 3 in the container-type storage 15, which is a fresh product of fruits and vegetables.
In the container type storage 15, there is a hole opened inside the storage box 3 so that ozone, negative ions and moisture penetrate from each side, and the container 3 does not damage the skin of the fruit. A plurality of storage boxes supported on a flat surface are stacked. The temperature signal of the temperature sensor 9 is output to the refrigerator through the control box 31 and the refrigerator is controlled so that the temperature becomes a predetermined value.

In order to preserve fresh products for a long time, this refrigerator takes measures against temperature, humidity, ozone and negative ions. In other words, the physical changes that cause deterioration and spoilage of food, such as evaporation, evaporation, and drying due to the loss of water due to sublimation, loss, shrinkage,
It is necessary to suppress surface shrinkage hardening, enzymatic or chemical decomposition and oxidation, and quality deterioration due to propagation of microorganisms. First of all, the lower the temperature, the longer the preservation period of the quality is, but the lower the temperature is, the lower the freezing point is, the lower the freezing point, the more the internal moisture will generate ice crystals, causing problems in freshness and taste. Don't go below C. The temperature of perishable products does not fall to 0 ° C.
Maintain the temperature inside the container at -5 ° C and indirectly cool from outside the container in order to prevent the cold air directly dried from hitting the preservation material and locally cooling the surface or evaporating and changing the moisture in that part. ing. Next, sufficient water is supplied to prevent aging due to water supply of fresh products such as fruits from trees. 9 relative humidity
Since the freshness retention days increase at 0% or more,
The humidifier 14 is adjusted while the humidity sensor 9 detects 95% or more of the humidity so that the surface of the stacked objects can always maintain this humidity. The higher the relative humidity, the better, but if water condenses on the surface of the food, it becomes water droplets and deteriorates the quality. Therefore, it is practically desirable to adjust the relative humidity to 95-97%. It is desirable that the humidifier 14 employs a steam humidifier that boil water that has a small water content to generate steam reliably, but it is preferable that an ultrasonic humidifier or the like be used without limitation. Is natural.

Although low temperature and high humidity are effective for maintaining the freshness of fresh products, when the humidity is high, mold is generated and quality is impaired. The negative ion / ozone generator 10 includes a blower that sucks and sends air in a container into a housing, a filter provided in the air passage for removing dust, and a fine wire electrode and a ground electrode connected to the air passage from which the dust is removed. A voltage is applied between these two electrodes to generate a corona discharge, causing a chemical change in oxygen in the air, and generating a mixed gas of negative ions and ozone near the fine metal wire electrode. Negative ions have a short life such as a half-life of several tens of seconds, and do not need to be controlled because they are generated as much as possible. In the case of negative ions, they escape when they are grounded, so the container may be kept in an insulated state. on the other hand,
Ozone has a half-life of about half a day and accumulates even at a small concentration. Ozone is highly concentrated and has a large bactericidal effect, but deteriorates foods and has an effect on the human body. In the case of ozone, the life is long, so that it diffuses and the concentration in the container becomes uniform. Since ozone has a strong oxidizing effect, take measures against metal rust.

As data on the effect of ozone and negative ion treatment on Staphylococcus aureus, which is a food poisoning bacterium, the sterilization rate is 9.3 in the case of treatment at 20 ° C. for 3 days and only 0.05 ppm ozone. Percent, 6 of 10
The germicidal rate is 9.8% when only the negative ion treatment of ions / cubic cm of the power is used, but when this ozone and negative ion are combined, the germicidal rate is about 10 times that of the case of each treatment alone, which is effective. It has been confirmed that proper sterilization is performed. In order to maintain the freshness of fresh produce for three months or more, for example, a cold and high humidity environment is used. Mold and bacteria generated in this environment are suppressed by negative ions and low-concentration ozone, and sterilization is performed. By doing so, the quality is maintained. From the above, for example, preservation of fruits with high freshness and storage for more than 5 times longer than before is possible. If timely shipment according to market price fluctuations not only leads to increase in sales, but also Can provide what you want. In addition, the refrigerator of the present invention can store and unload small articles and store fruits having different storage periods without affecting other items, and can use the equipment efficiently. In addition, a system that uses containers from the production site to the retail store and is safe and does not cause product loss can be obtained.

FIG. 4 is an explanatory view of an ozone concentration control device for controlling the concentration of ozone from the negative ion / ozone generator 10 inside the container type storage. FIG. 5 is a characteristic diagram illustrating the relationship between the amount of ozone generated from the negative ion / ozone generator 10 and humidity. In the figure, 16 is an input / output unit, 17 is a calculation unit, 18 is an ozone generation target to be generated in the container according to the data such as the relationship between the ozone generation amount and the humidity described in FIG. A storage unit in which values and the like are stored is an input device 19 for inputting the type and amount of the stored object 5 to be stored. As shown in FIG. 5, as the humidity increases, the amount of ozone utterance decreases. First, the type and amount of the object to be preserved and the start of the ozone generator are input from the input device 19. Next, the input / output unit 16 inputs the signal of the temperature sensor 13 and transmits the signal to the calculation unit 17. Arithmetic unit 1
At 7, the storage unit 18 transmits the applied voltage and frequency of the AC voltage applied between the electrodes to the negative ion / ozone generator 10, which are the target values of the ozone generation amount, based on the humidity and the signal from the input device. The detection device may detect that the ozone generation amount has reached the target value, or may determine that the ozone generation amount has reached the target value by reaching the set time. In this case, it is possible to detect the ozone generation amount with high accuracy by setting the time and the target value stepwise at the time of startup. When the target value is reached, the calculation unit 17 reads out the applied voltage and frequency corresponding to the amount of ozone generated at which the ozone concentration in the container 15 becomes a constant concentration from the storage unit 18 based on the 13 signal of the humidity sensor, and via the input / output unit. To the negative ion / ozone generator 10. As described above, the ozone concentration control device 11 constantly detects the humidity and controls the ozone concentration according to the humidity.
As a means for controlling the ozone concentration in the container type refrigerator 15, an ozone concentration sensor may be installed in the container to control the negative ion / ozone generator.

In the negative ion / ozone generator, when the voltage between the thin metal wire electrode and the metal ground electrode is kept constant and the frequency is changed, the amount of generated ozone changes. Since ozone has a strong oxidizing effect, it is controlled at 0.03-0.1 ppm so that the concentration in the air does not become 0.1 ppm. Operation of the ozone generator at 1 kHz almost stops the generation of ozone and reduces the ozone concentration in the container to 0.03 pp.
m. On the other hand, the negative ion is 0.1 at 4 kHz.
The same is true for kHz, and the ozone generator can be controlled to turn on and off the generation of ozone while continuing to generate negative ions. The ozone concentration control device 11 is operated with this ozone generation amount, and controls at 0.05 ppm or less including the influence of humidity.

In the description of FIGS. 1 to 4, the container type storage 15 is used to keep freshness not only in the refrigerator from the time of shipment from the production side to the consumption side, but also in the refrigerator at the time of distribution. However, the distribution time is short, and the storage box 3 is not necessarily a closed container type storage 15.
The fruits and vegetables may be stored in a refrigerator and transported in a cool state by the cooler 27. By providing a humidifier inside the insulated car, a low temperature and high humidity state can be formed and fruits and vegetables can be transported fresh. Further, an ion generator may be provided inside the cold storage vehicle, but it is less necessary for short-time transportation. However, if negative ions are generated or applied to the storage box 3 in order to generate negative ions during the physical distribution or to enhance the negative ions in the refrigerator, it becomes a countermeasure against bacteria adhered by carrying the storage box or the like. The negative ion generating material is a composite that releases positive and negative ions by rare earth natural ore and silicon, rubber latex, etc., and suppresses positive ions and releases a large amount of negative ions. To the storage box 3 in the form of
In this way, when negative ions are generated from the storage box for storing fresh products, the short-lived negative ions generated from the ozone generator are difficult to penetrate. Negative ions are provided. Further, by providing a surveillance camera for monitoring the surface condition of the object to be stored stored in the container type storage, or an image means such as a retinal chip, the storage state of the product in the refrigerator or being transported is monitored. I can do it. It should be noted that data relating to the image in the container is transmitted from a transmitter provided in the control box 31. In addition, by transmitting and receiving the stored state by image communication such as the Internet, the consumer can also view the stored state, and can place a purchase order with peace of mind while looking at the thing.

As described above, according to the method of the present invention, when the harvest time is not extended even if the harvest time is deviated by house cultivation or the like as in the case of conventional open-air products, the time when the fruits have the best tasting quality is improved. It can be shipped freely during the storage period while monitoring the market price and the amount of harvest, so that the profitable time and quantity can be selected by looking at the forecast data regardless of the harvest time. For example, 9
Assuming that the month is the harvest time of the field, the period from October to December is the preservation period and the sales period, and the demand at the end of the year is concentrated.
The harvest and sale of fresh produce can be freely shifted, with the condition that the freshness is preserved, for example, three months, so that it can be profitable for producers and consumers because it can be sold on the moon. I can do it. In addition, it is possible to constantly monitor the refrigerator for storing fruits and abnormalities during storage during distribution, and to promptly dispatch a maintenance service to obtain highly reliable storage and distribution of fresh products.

This concept will be described with reference to the flowchart of FIG. Fig. 6 shows an example of harvesting peaches at Wakayama and selling them in the Kansai area. In S01, a farmer in Wakayama can harvest the peaches at their own quality in July and send harvest information including images of peaches. I do. In S02, the storage / distribution company purchases the product, enters the refrigerator 1, sets a long-term storage system using low-temperature, high-humidity ozone negative ions, and transmits storage information together with a storage state image. In step S03, the computer 24 transmits data such as the temperature and humidity in the storage as information from the computer 22 in charge of the operation of the refrigerator to the communication line 26.
The storage quality is checked based on comparison with past data and the storage quality is checked (S04), and the storable period is determined to be until September, and this information is disclosed. In S06, the computer 24 estimates the yield of peaches in the other regions of August, especially in the Tohoku region, where many past records have been received in the Kansai region, based on information obtained by comparing the past harvest results with the current producers. Estimate this year's quantity and quality against the annual quantity and quality. According to information from producers in the Tohoku area in July, growth and harvest conditions are 4
Since the current situation until the month is low and the trend up to this time is not changed every year, it is predicted that the harvest in August will be slightly low, and will be -1 on a computer.

On the other hand, in S07, +1 is calculated from the fact that peach is preferred due to the expectation that the weather condition in the Kansai area will be hot in August and the past sales results of July and August and the user's reaction to the advertisement. Is done. In step S08, information indicating that the present condition is the same as that of the ordinary year is obtained from the computer 23 as the purchasing power information of the consumer, and 0 is recorded. In the prediction of the purchasing power of the consumer in S09, +1 remains. As a result, in S10, the demand side becomes +1 in the prediction that the demand in August will be strong, and the supply side becomes -1 from the prediction of the decrease in the yield in the Tohoku area. Since the selection of the selling time is considered first by comparing the timings, whether to sell immediately in S11 or S12 or to sell in August determines whether there is a relationship between supply and demand. In this case, August is +1-(-1) = + 2
Because supply greatly exceeds demand, the selling price is expected to rise above the relationship between demand and supply in July, which is the current month, and it can be concluded that the refrigerator will be shipped to consumers in August. If it is predicted from the past case that supply will exceed supply in August, then a determination for September is made in the same manner as above.

FIG. 7 shows a flowchart of the shipment timing judgment means for making a simple judgment based on the above example. In FIG. 7, the selling time is first set to August in S21. S22
Is determined to be within the storage period, and if August is different from the storage period, the product is immediately sold as in S34. If it is within the storage period, the harvest situation at the time of sale is predicted in S23. As a prediction, when S24 is the same as or increases from the previous year, S25 is a drastic decrease, S26 is a slight decrease, and B = + 1, -2, -1. . As a prediction, S28 is a case where it increases more than usual, S29 is the same, S30 is a case where it decreases, and A = + 1, 0, −1, and then AB>
Check if it is 0. If this result is positive with respect to the set sales time, that is, if the supply is predicted to decrease and the demand increases, it is determined that the sales will be performed at the set time. If the result is 0 or-, that is, if the demand and supply are in the same or worse direction as in the previous year, the selling time is again delayed and set again, and the same judgment is repeated. In addition, the numerical value described in FIG. 7 is intended to promptly process a perishable fresh product such as peach in order to quickly process it, so that the situation in which the harvest is greatly increased is determined immediately.
You can change this value depending on the type of fresh food,
Alternatively, the value may be increased during a time when the demand increases significantly, such as at sunset. Alternatively, it is easy to change the sales of a sale that has a large advertising effect, so that the content can be input using a keyboard so that the content is represented by a numerical value.

FIG. 8 is a flowchart when the stock side purchases from the production side. First, the stock side presents the free information up to three months from the current state of the refrigerator storage space known by the computer 22 to the computer 24 of the storage and distribution company and the computers 20 and 21 of the farmers and agricultural cooperatives together with market information. I do.
However, this vacancy information is based on the shipping date and shipment quantity that has already been contracted with the consumer side, and the shipping date and planned quantity that has been presented to the consumer side before the contract but has already been presented to the consumer as a sales schedule. Is displayed. The inventory holding the refrigerator 1 may request the variety, price, and quantity of fresh products, or may freely present it from the producer. Here, based on the information from the consumer side, the refrigerated storage company presents to the producers, as guidelines, data that predicts the peach quality, price, and quantity conditions that are easy to sell, and data that predicts changes in sales prices during the peach storage period. It should be noted that the stock side may be performed by the department in charge of holding and operating the refrigerator, and may be performed by a storage and distribution company, a supermarket, or an agricultural cooperative. In that case, the producer will be a farmer or an agricultural cooperative. Several producers participated in the storage tender by presenting the quality, price, quantity, and available date of peaches that can be sold by communication to the free space of the refrigerator, and the stock side purchased quantity,
Determine the date and time, the place of purchase, and place an order with the producer. In this case, the stock side sometimes considers the operation of the refrigerator and sells to the consumer and accepts it under conditions that are worse than the first condition presented.

Next, FIG. 9 is a flowchart when the stock side sells to the consumer side. First, the stock side presents the storage information of the fresh product stored in the refrigerator, which is grasped by the computer 22, together with the harvest information to each consumer such as a supermarket or a retailer, including the image information. In this information presentation, prices and quantities predicted in chronological order from the current state to three months ahead are presented as guidelines. Each consumer responds to the purchase bid by presenting the quality, quantity, price, and delivery date of the fresh product to be purchased, for example, peach. It goes without saying that both good and bad conditions can be met. The stock contracts with each consumer individually, judging from the bidding conditions and harvest information.

It should be noted that a bid for a storage order from the production side is made on the side of the consumer side, such as a storage / distribution company or a supermarket, which owns the refrigerator of the present invention. On the other hand, as a position to receive a bid for a purchase order from the consumer side, the storage and distribution company or the agricultural cooperative having the refrigerator of the present invention will perform the process. In particular, from the standpoint of bidding as a third party, such as a storage / distribution company, it is necessary to establish transparency of information, and to publish harvest information, storage information, and market information, or to share the same harvest information. By storing the container as it is or shipping it to the market, information and goods can be treated as one and the transparency of the information can be improved. In addition, the ability to examine the received information and determine whether it is reliable, and the ability to use this information at a high level and process it like the shipping time determination means described above to obtain the reliability of predictions that do not cause failure loss Is needed, so that trust can be gained from both sides of the conflict.

As described above, the present invention maintains the freshness of a fresh product which is produced in large quantities due to the overlap of the harvests in each region, and which maintains its freshness in a low-temperature and high-humidity refrigerator for a long period of several months. This ensures stable distribution while preventing the occurrence of loss. Also, depending on the region, fresh products that are harvested in different seasons and in different amounts can be obtained at a low price by many consumers in many regions using long-term storage refrigerators located in various places. In addition, by using this long-term storage refrigerator and judging the shipping time based on harvest information and market information, the production side has more room for the choice of shipping of the harvested product, and it is possible for the consumer side to pursue profits. A system is obtained that allows the necessary quantities to be obtained at a reasonable price in time. This enables management from a long-term perspective in various business forms from production to consumption. In addition, producers such as farmers and cooperatives, as well as consumers such as supermarkets, retailers, and general consumers, can obtain necessary information at any time, and can participate in sales and purchases at their own risk with transparent information.
