Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food freshness maintaining device applied to refrigerators, refrigerating showrooms, cooking rooms and the like.

[0002]

2. Description of the Related Art There are various kinds of foods from so-called fresh foods to various processed foods and frozen foods, and foods are usually preserved by low temperature control. Refrigerators and freezers are convenient means for controlling low temperature at home.

A refrigerated showcase is required to have a function as a refrigerator for keeping products at a low temperature in a retail store and a function as a display case for displaying products. Especially in showcases of sushi restaurants, it is required to maintain a high degree of freshness of sashimi so that customers can immediately respond to their orders.

[0004] Food is stored at low temperature in order to suppress the growth of microorganisms such as bacteria and bacteria and prevent spoilage and poisoning of food. And the reproduction of microorganisms cannot be completely suppressed. When stored below -10 ° C, microbial growth almost stops, but when food freezes, the tissue is destroyed. Therefore, the freshness and quality are inferior to the fresh foods, but the frozen foods further deteriorate significantly in the freshness and quality if the thawing method is wrong.

As a method for storing foods and the like without losing their freshness, Japanese Patent Publication No. 58-79006 (refrigerator) has introduced a method using fine water droplets. This method draws out a gas such as air or an inert gas in a refrigerator, contacts it with water droplets of a low-temperature liquid generated from a gas-liquid spray contact device to form a low-temperature humidity saturated gas, and then drops water droplets from the low-temperature humidity saturated gas. Is removed, and this gas is sent into the refrigerator to cool the inside.

According to this refrigerating apparatus, the air in the refrigerator is kept at a low temperature and saturated humidity, there are no extra water droplets, and bacteria are removed. Therefore, fresh foods such as vegetables and fresh fish are never dried, Can be stored for a long time.

The reason why the bacteria in the refrigerator can be removed by using the refrigerating apparatus is that the water droplets generated from the sprayer and the gas sucked from the refrigerator are in contact with each other by gas-liquid contact to catch dust or bacteria with small water droplets. It is described that the air is purified by dropping it, but it is clarified that this is a generation effect of air ions in a later study (Japanese Patent Laid-Open No. 4-141).
179).

In recent studies, negative ions contained in the air have a dust removing effect, a bacteria removing effect, a deodorizing effect, a gas component removing effect, a humidity controlling effect, an antistatic effect, and a favorable effect on the growth of animals and plants. It became clear that negative ions were caused by the negative ions.

Conventionally, as a method of artificially generating negative ions, a negative ion generator of the type in which positive and negative ions are generated by utilizing corona discharge and the positive ions are captured and the negative ions are taken out has been used. When using this method,
It was found that ozone and nitrogen oxides, which are harmful to the human body, are generated as by-products.

In Japanese Unexamined Patent Publication (Kokai) No. 4-141179, negative ions are generated by splitting water to generate fine water droplets and removing water droplets having a particle size of 1 μm or more from the air containing the fine water droplets to generate anions. A method and apparatus is disclosed.

[0011]

This method is intended to faithfully realize the Leonard effect by combining the generation of air ions generated when a water drop collides with a metal plate and the selection of the particle size of the water drop. Although the mechanism is extremely simple, the technical meaning of fragmentation and the technical meaning of separation have not been clarified, and negative ion generation may occur depending on the concept of combination of water droplet breakup and water droplet size selection. The amount depends on the jet pressure of water and the performance of the cyclone separator that is a separator.To increase the amount of negative ions generated, use a high-pressure pump, enlarge the cyclone separator, and use a powerful pump and fan. There is no choice but to increase the water injection pressure and increase the sorting capacity. In addition, just generating fine water droplets from water as a more fundamental issue does not necessarily mean that water droplets are effectively ionized, just as the generation of water droplets depends on the height of the waterfall and the shape of the rocks. There is no guarantee that it will be done.

Maintaining the freshness of food is a matter of time, and is not the only problem with refrigerators at home and refrigerated showcases in stores. Fresh food is transported from the production area to a refrigerating warehouse by a refrigerating carrier or a refrigerating vehicle, and the quality of the fresh food deteriorates every moment during the storage in the refrigerating warehouse and during the transportation from the refrigerating warehouse to the store. Go on. Preserving the freshness of fresh foods can be said to be a problem that must be addressed from the production area to the kitchen or kitchen.

The purpose of the present invention is to clarify the mechanism of negative ion generation as functionally as possible and efficiently perform each function to maintain an atmosphere containing negative ions necessary for maintaining the freshness of fresh food. To provide a device.

[0014]

In order to achieve the above object, the food freshness maintaining apparatus according to the present invention is a food freshness maintaining apparatus having a storage chamber and a negative ion generator, wherein the storage chamber is fresh. Preservation and transportation of foods that should maintain

[0020]

In the present invention, the storage room means a room in which foods that need to be kept fresh are stored, and is a container for vehicles, a cargo hold of a ship, a warehouse, a refrigerator, a showcase, a cooking room, a defrosting room. , Including a fostering room.

FIG. 1 shows the basic system of the present invention.
In FIG. 1, according to the present invention, a negative ion generator 1 is attached to a storage chamber 8. The negative ion generator 1 is roughly divided into a combination of a centrifugal force / Coriolis force generator 2 and a gas-liquid separator 4. The centrifugal force / Coriolis force generator 2 is functionally an ion dissociation mechanism, a droplet activation mechanism, and a vaporized molecule ionization mechanism.

The centrifugal force / Coriolis force generator 2 is supplied with the water in the tank 9 pumped up by the pump 10.
The air in the storage chamber 8 is sucked and supplied by the fan 3.
The gas-liquid separation device 4 separates the negative ion-containing air output from the centrifugal force / Coriolis force generation device 2 from water droplets and sends the air into the storage chamber 8 under pressure. When the storage room 8 is a refrigerator, it is convenient to attach a refrigerator 19 to the tank 9 to cool the circulating water, but a refrigerator may be provided in the storage room to control the temperature. However,
In the present invention, the freezing function is not always necessary to maintain the freshness of food.

Although FIG. 1 shows a state in which the storage chamber 8 is connected to the input side of the fan 3 and the output side of the gas-liquid separation device 4 by piping, the negative ion generator is not always stored. It does not mean that it is installed outdoors. A negative ion generator may be installed in the storage chamber 8 and the intake port of the fan 3 and the air supply port of the gas-liquid separation device 4 may be opened indoors.

The mechanism of negative ion generation is functionally an ion dissociation treatment performed by an ion dissociation mechanism, a droplet activation treatment and a droplet activation treatment by a gas molecule ionization mechanism, and a gas molecule ionization treatment. The gas-liquid separation process performed by the gas-liquid separation mechanism is sequentially executed, but each process is not always clearly distinguishable. The technical meaning of each process will be described below.

Ion Dissociation Treatment Ion dissociation treatment is a treatment for dissociating water.
When high energy is given to liquid (water), water (H ₂ O)
Is ion-dissociated like H ₂ O → H ⁺ + (OH) ⁻ to form a charge double layer in the liquid as shown in FIG. 2, and an oriented dipole is formed on the surface of the liquid in contact with air. Negative ions will be arranged outward,
More negative ions are attracted near the liquid surface. If the liquid is mechanically divided into small water droplets by some method here, the net charge of the water droplets becomes negative, and the positive ions are left as large particles in the liquid or neutralized through grounding. Will be done (Static Handbook,
P104. (See Ohmsha, edited by The Static Electricity Society).

High energy as the ion dissociation treatment is
It can be applied mechanically, electrically, electromagnetically, optically, or by irradiation. The water droplet splitting is a mechanical ion dissociation treatment. However, if the ion dissociation treatment is performed prior to the splitting, the amount of water molecule-added negative ions generated can be increased by 2 to 5 times.

The liquid droplet activation process is a process in which high energy is applied to the ion-dissociated liquid particles to accelerate them.
Since high energy is applied to the liquid particles, ionic dissociation is further promoted, fragmentation progresses, aerodynamic transport is carried out at high speed, and the droplet interface is activated.

In the present invention, the liquid droplets are split in a high-speed air stream, and the centrifugal force and Coriolis force are applied to activate the interface in a short distance and in a short time. A method of applying a centrifugal force to the droplet particles is to cause the droplet particles to make a swirling motion. Coriolis force is one of apparent forces acting on a moving object in a rotating coordinate system. When the angular velocity of rotation is ω and the mass and velocity of the mass are m and v, the Coriolis force is 2m × ω × v
Given in. The Coriolis force due to the rotation of the earth works in the opposite direction in the northern and southern hemispheres, and in the northern hemisphere, it becomes to the right with respect to the traveling direction. Set the turning direction. By effectively applying the Coriolis force, it is possible to obtain energy at a distance of several cm when a droplet drops by several hundred meters.

The activation of the interface means that the dipole moment of water causes the dipoles to be oriented to form a dipole double layer, and negative charges are released when the negative ions are arranged outward. is there.

H ⁺ : OH in infinitely fine droplets
^- it is, but are attracted to each other by van der Waals force, a powerful centrifugal force (mrω ²⁾ and Coriolis force (2mv
ω), the mass difference between H ⁺ and OH ⁻ (H ⁺ =
1, OH ⁻ = 17) makes it easier for OH ⁻ to orient outward, and releases a negative charge when the dipole is oriented.

Ionization Treatment of Gas Molecules The ionization treatment of gas molecules is an inevitable treatment after the activation treatment of the droplets.

Oxygen (O ₂ ) molecules present at the interface on the gas (air) side when the dipole is infinitely miniaturized while moving with high energy being obtained and the dipole is oriented on the surface of the water drop. the ^{_{ionized, O - 2 · (H 2}} O) minus that appears by n (negative) the ion molecular groups (see supra electrostatic Handbook P317). This negative (negative) ion molecule group is called a water molecule-added negative ion. As a result, water droplets will get the same amount of positive charge as the ions generated during fragmentation (see P27, Meteorology and Electronics).

Gas-Liquid Separation Treatment The gas-liquid separation treatment is a treatment for separating air containing water molecule-added negative ions from droplets. Gas-liquid separation must be performed quickly before recombination of positive and negative ions occurs. However,
The particles of the droplets are substantially separated by centrifugal force while swirling under the action of a strong centrifugal force, and further, the droplets are separated through a cyclone separator to store the air containing water molecule-added negative ions in the storage chamber 8 Blow inside.

The positive ions left in the droplets can be arbitrarily taken out if necessary, but when they are not needed, they are returned to the liquid tank and neutralized by grounding.

The dust, odors, bacteria, etc. floating in the storage chamber 8 are sucked by the fan 3 and captured in the liquid in the centrifugal force / Coriolis force generating device 2, and the centrifugal force / Coriolis force generating device 2 Negative ions and fine water droplets that are generated in large quantities at are filled in the storage chamber 8 by being extracted by the gas-liquid separation device 4 and form an atmosphere of high-humidity air at a low temperature and close to 100% inside the storage chamber 8. The ion-containing air directly acts on the food in the storage chamber 8 to prevent it from drying, sterilize bacteria and viruses adhering to the surface of the food to suppress the growth thereof, and substantially keep the room sterile. Suppress the deterioration of food quality. In the present invention, the fact that the temperature of the storage chamber is equal to or lower than room temperature means that heating is not included for storage. However, temporary heating for thawing is free.

To maintain the freshness of the food in the storage chamber 8, it is sufficient to maintain the atmosphere of high-humidity air containing substantially 1,000 / cc or more negative ions in the room. In order to maintain 1,000 ions / cc or more of negative ions, it is desirable to continuously supply while generating 10,000 ions / cc or more of negative ions in the source. By utilizing Coriolis force together with centrifugal force to activate the droplet, activation of the droplet and subsequent ionization of vaporized molecules can be realized within a small volume.

EXAMPLES Examples of the present invention will be shown below. In FIG. 3, in the embodiment, the negative ion generator 1 is provided outside the storage chamber 8.
An example in which is attached is shown. The negative ion generator 1 comprises a combination of a centrifugal force / Coriolis force generator 2 and a gas-liquid separator 4.

The centrifugal force / Coriolis force generator 2 has an intake port 5, a liquid suction port 6, and an exhaust port 7. A high-speed airflow generator 3 is connected to the intake port 5 to blow outside air, and an exhaust port 7 is provided. The air from which the liquid has been separated by connecting the gas-liquid separation device 4 is sent from the output port. A tank 9 is connected to the liquid suction port 6 via a pump 10 to supply the liquid in the tank 9. In the embodiment, the output pipeline of the gas-liquid separator 4 and the input pipeline of the high-speed airflow generator 3 are opened to the storage chamber 8 to form a circulation system. In addition, in the embodiment, the negative ion generator 1 is installed outside the storage chamber 8 and is connected to the storage chamber 8 through the conduits 11 and 12, but alternatively, the negative ion generator 1 is placed inside the storage chamber 8. When installed, the air supply port of the gas-liquid separation device 4 and the air intake port of the high-speed airflow generation device 3 can be opened to the storage chamber 8 and used as an indoor installation type.

The centrifugal force / Coriolis force generator 2 is a mechanism for performing ion dissociation processing, droplet activation processing, and gas molecule ionization processing. In the embodiment, in the horizontal aerodynamic force transfer tube 13, A spiral guide 14 is arranged along the axis, a nozzle pipe 15 is provided on the axis, and a water tank 16 is attached to the lower peripheral surface.

The water in the tank 9 is transferred to the water tank 16 by the pump 10.
The water in the water tank 16 is pumped up by the pump 17 and is sent to the nozzle pipe 15. The tank 9 is equipped with a refrigerator 19 and cools the supplied water to a required temperature.

The guide 14 guides an air flow in the aerodynamic force transfer pipe 13 to swirl the pipe axial direction in a spiral shape. The nozzle pipe 15 is at the axial center of the aerodynamic transport pipe 13, and the gas makes a swirling motion around it, so the guide 14 is not always necessary, but the guide 14 is used in the embodiment. Thus, the direction of the swirling direction of the airflow is regulated so that the Coriolis force points in the direction of the angular velocity vector of the rotation of the earth. However, if the gas feeding direction from the high-speed airflow generator 3 is set to be tangential to the inner circumference of the aerodynamic transport pipe 13, the swirling direction of the airflow is naturally set to the clockwise or counterclockwise swirling flow. To be done.

Nozzles 18 are opened along the axial center of the nozzle pipe 15 at important points on the circumferential surface.
The liquid supplied from 6 is jetted into the swirling airflow in the aerodynamic transport pipe 13. In the embodiment, the nozzle 18 is an ion dissociation mechanism. The water is ejected from the nozzle 18 at a high pressure, obtains energy, and is ionized. However, if the water that has been subjected to the ion dissociation treatment in advance is supplied into the pneumatic transport pipe 13,
Ion dissociation is further promoted.

The high-speed airflow generator 3 is a fan for blowing air. In the embodiment, the air in the storage chamber 8 is sucked,
The air is blown into the aerodynamic transport pipe 13 through the intake port 5.

The gas-liquid separator 4 uses a cyclone separator in the embodiment. The cyclone separator is effective for centrifugal separation of gas and liquid as long as the air flow containing fine water droplets discharged from the exhaust port 7 of the aerodynamic transport pipe 13 can obtain a wind velocity and wind pressure above a certain level. The air that has been separated into gas and liquid is introduced into the storage chamber 8 through the conduit 11.

In the embodiment, the high-speed airflow generator 3 is activated, the water in the water tank 16 is pumped up by the pump 17, and the swirling flow of the powerful airflow generated in the aerodynamic force transfer pipe 13 from each nozzle 18 of the nozzle pipe 15. Eject it inside.

The water jetted into the aerodynamic transport pipe 13 is subjected to gas pressure, is split in the swirling air current, and is dissociated into ions.
Fine water droplets are pneumatically transported in the pipe while swirling along the guide 14. During this time, water drops flow in the axial direction toward the tube wall under the action of the centrifugal force generated by the swirling flow of the air current and the Coriolis force, the interface of the water drops in contact with the gas is activated, and the surface of the water drops is bipolar. When the child is oriented, oxygen molecules existing at the gas side interface are ionized.

The air flow containing air ions is generated by the aerodynamic force transport pipe 1.
Water droplets remaining in the gas are removed from the gas-liquid separation device 4 through the exhaust port 7 of No. 3, and the gas containing air ions is subjected to laminarization treatment, and is supplied from the pipe line 11 into the storage chamber 8 as supply air. The air in the storage chamber 8 introduced into the
Is sucked into the duct 12 and supplied with the newly introduced outside air, and is again sent to the centrifugal force / Coriolis force generator 2 by pressure.

On the other hand, the water droplets adhering to the pipe wall of the aerodynamic transport pipe 13 and the water droplets separated by the gas-liquid separator are returned to the water tank 16. Since many positive ions are contained in this water droplet, the tube wall is grounded and neutralized.

As described above, in the embodiment, the horizontal centrifugal force / Coriolis force generator is shown, but the arrangement direction thereof is not limited at all.
