DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat generating and evaporating apparatus for evaporating (spraying) a medicine and heating food and the like using heat generated by a chemical reaction, and a method therefor. In more detail, water vapor is supplied to a substance that causes an exothermic reaction by water vapor, and the generated heat heats food in a short time, or evaporates a transpirable drug in a short time, and is used for agricultural use in a room or other limited space. The present invention relates to an apparatus and a method for controlling pests, sanitary pests, fungi, odors, etc., and evaporating (spraying) fragrances and fragrances.

2. Description of the Related Art Conventionally, as a method of exterminating insect pests by emitting a pesticide or the like in a short time, a so-called method of mixing a medicine and a burning agent to emit the medicine by the combustion heat and smoke of the burning agent. A method using a smoker, a formulation prepared by mixing an organic foaming agent with a drug, indirectly heats the product by the heat of reaction between calcium oxide and water to decompose the organic foaming agent, and emits by the gas generated and the heat of reaction (Japanese Patent Publication No. 59-49)
No. 201, Japanese Patent Publication No. 60-55481).

[0003] The above-mentioned method using a smoking agent has the following problems. That is, in order to quickly evaporate a large amount of smoking chemicals, it is necessary to burn a burning agent, but the gas generated during this burning has a toxic or undesirable effect on animals and plants. There is also a risk of fire. In addition, there is a thermal decomposition of the drug due to the heat of combustion and a reduction in the effective volatilization rate of the drug (that is, a reduction in the effect due to the loss of the drug).
In addition, there may be risks when producing smokers,
The process is also complicated.

[0004] A preparation containing the above-mentioned drug and an organic foaming agent is heated indirectly by the heat of reaction between calcium oxide and water to decompose the organic foaming agent and emit the drug by the gas generated and the heat of reaction. There are the following problems in such a method. That is, the amount of gas generated when the organic foaming agent is decomposed is small, and the amount of diffusion gas necessary to emit the drug is insufficient, so that when used in a large space such as an agricultural house, a large amount of gas is used. Requires transpiration. Further, the gas generated by the thermal decomposition of the organic foaming agent often has an unpleasant odor. Further, since the exothermic reaction between calcium oxide and water is used, the exothermic temperature does not become higher than about 260 ° C. Therefore, it cannot be used for the evaporation of a drug having a high evaporation temperature. Further, in order to realize a predetermined heat generation temperature, it is necessary to supply a certain amount of water accurately to a certain amount of calcium oxide at the start of heat generation, and the control thereof is difficult or complicated. This often makes complete evaporation of the drug impossible or difficult. As in the case of the other methods, there may be danger in the production of the preparation, and the process is complicated.

Another example of the first heat generating means capable of generating water vapor is a combination of a heat source (for example, a heater or a fuel heater) and water. Specifically, a heat source, for example, a heating wire such as a nichrome wire, a sheet heater, a heater using a semiconductor, or the like is disposed adjacent to the water storage container, and electricity is supplied to generate water vapor from the water storage container. In order to generate steam of 2 liters or more per minute, the capacity of the electric heater is preferably about 100 to 300 watts.

The first heat generating means capable of generating water vapor and the second heat generating means containing a substance which generates heat by reacting with water, the water vapor generated by the first heat generating means reacts with the water of the second heat generating means. It is arranged to generate heat by reacting with a substance that generates heat.
Usually, above the first heat generating means, a second heat generating means separated by a gas-permeable partition wall material made of a flame-retardant or non-combustible material is arranged, and the steam generated by the first heat generating means is naturally discharged. Or the water is pressurized by the water vapor to rise and react with a substance which reacts with water and generates heat by reacting with water in the second heat generating means disposed above, thereby generating heat. The arrangement method is not limited to these. For example, the first heat generating means capable of generating water vapor may be arranged above the second heat generating means.

As the partition wall (3) made of a flame-retardant or non-combustible material having air permeability, water vapor (and other gases) generated from the first heat-generating means easily passes through the second heat-generating means. It has air permeability enough to come into contact with “a substance that reacts with water and generates heat”, and has a high temperature, for example, about 400
C., preferably about 500 ° C.,
In addition, any water can be used as long as the water (liquid water) supplied to the first means can be prevented from coming into direct contact with the “substance that reacts with water and generates heat” in the second means. . For example, glass fiber cotton, glass fiber cloth, metal mesh, perforated plate (for example, ceramic, metal (for example,

The “material that reacts with water and generates heat” particularly suitable for use in the second heating means is steam (water).
Any substance can be used as long as it has a particle size that allows water vapor (or a mixture of water vapor and another gas such as hydrogen) to easily pass. The following are specific examples.

[0015] The present invention further provides a first method capable of generating steam.
The water vapor generated by the first heat generating means includes a heat generating means, a second heat generating means including a substance which generates heat by reacting with water, and an object to be heated. material"
And a heating device configured to heat the object to be heated by the heat. Also in this heating device, a second heat generating means separated by a gas-permeable partition wall material made of a flame-retardant or non-combustible material is arranged above the first heat generating means, and further above the second heat generating means. By arranging the object to be heated (evaporative medicine or food), the water vapor generated by the first heat generating means rises naturally or by being pressurized by the water vapor, and rises by the second heat generating means disposed above. It reacts with “a substance that generates heat by reacting with water” to generate heat.

The object to be heated includes food (eg, instant food, beverages such as tea, coffee, and sake) and transpirable substances (eg, insecticides, fungicides, repellents, rodenticides, deodorants, aromas). Agents, perfumes). More specifically, a vapor-generating flame-retardant material or a substance (2) that reacts with water and generates heat when reacted with water is placed in a container (10) made of a flame-retardant or non-flammable material. It is housed through a partition (3) made of noncombustible material, and the object to be heated (4) is placed above the substance (2). The object to be heated (4) is contained in a bag made of a packaging material, for example, a synthetic resin film (for example, a heat-shrinkable synthetic resin film) or the like, or contained in a capsule made of gelatin or the like. After being adsorbed by an adsorbent such as diatomaceous earth or zeolite, it is packaged with the above packaging material and placed above the substance (2). In the steam generating means (1),
When a predetermined amount of water is supplied from the outside (or the inside of the container), steam (and other gases) is generated. The generated steam (and other gas) naturally or by the steam and the gas pressure passes through the partition (3) and reacts with the substance (2) to generate heat. The object to be heated (4) is heated by this heat generation. In the case where the object to be heated is a transpiring drug, if the packaging material of the object to be heated is made of a heat-fusible or heat-destructible material, the packaging material is melted by heat and the container is destroyed. The drug spreads on substance (2) and is heated and evaporates into the atmosphere. When steam is generated by the reaction between the substance (2) and steam, it is considered that the evaporation of the drug is promoted by a kind of steam distillation mechanism. In addition, the exothermic temperature is controlled by adding an arbitrary amount of water and a surfactant (eg, polyoxyethylated castor oil, polyoxyethylene nonylphenyl ether, calcium stearate) and the like to the drug to form a hydrate. However, it is possible to prevent the drug from being thermally decomposed due to an excessively high heat generation temperature.
The substance (1) and the substance (2) are reacted in a container capable of withstanding a sufficient pressure (30 kg / cm ² ) and the substance to be heated and evaporated, and a nozzle (diameter of about 0.01 to 2 mm) provided in the container is provided. It is possible to scatter the medicine or the like intensively even in the gap between the objects by releasing from the tube.

[0017]

According to the present invention, when the water vapor is brought into contact with the "substance which generates heat by reacting with water", it is much higher than when the liquid substance is brought into contact with the "substance which generates heat by reacting with water". It has been completed based on the finding that an exothermic temperature can be obtained. Therefore, it is possible to spray (evaporate) a medicine having a high boiling point, which has been difficult in the past, and it is possible to sufficiently heat food, which was insufficient with the conventional apparatus. It is desirable that the heating temperature can be arbitrarily controlled during the heating of food or the evaporation of the drug, particularly the evaporation of the drug. In the present invention, an arbitrary amount of water or water and a surfactant (eg, polyoxyethylated castor oil, polyoxyethylene nonylphenyl ether, calcium stearate, alkyl (C8-C14) sulfate (Na), polyethylene) Glycol (molecular weight 4000-6000), fatty acid ester,
By adding carboxymethylcellulose, gum arabic) and the like to form a hydrate, the exothermic temperature can be reduced, and the medicine can be efficiently vaporized (sprayed) while preventing the decomposition of various kinds of drugs. In addition, the generated water vapor helps to evaporate (spray), and when other gas (for example, hydrogen) is generated together with the water vapor, these gas and the water vapor are used to quickly spread the material to be heated and transpired. As it works, the pressure inside the container increases, helping to deliver the drug faster. Further, since oxygen (air) in the container (10) is replaced, decomposition of a drug which is easily decomposed by heating in oxygen can be suppressed.
