Description
The present invention relates to a highly efficient multifunctional dehumidifying drying apparatus used to dry food, herbal medicines, agricultural and marine products.
In particular, the present invention relates to a highly efficient multifunctional dehumidifying drying apparatus for minimizing heating energy and forming optimum evaporation conditions in order to obtain high quality dry materials at low cost.
More specifically, the present invention uses a thermoelectric element that performs cooling and heat dissipation at the same time to utilize all of the cooling capacity generated from the thermoelectric element for the dehumidification effect, and the heat radiated to heat the dehumidified air By using all of them, it is to provide a highly efficient multifunctional dehumidification drying apparatus in which all electric power is consumed for cooling and heat dissipation by a simple structure.
In general, various kinds of dried foods to be dried include a variety of products such as forest products such as mushrooms and herbal medicines, agricultural products such as peppers and grains, and seafood products such as seaweed and anchovy.
In addition, a drying process is performed for the purpose of effectively storing, distributing, storing, and reducing the forest products, agricultural products, and marine products as described above.
Here, the definition of the drying, the dry refers to all means for appropriately reducing the water contained in the dry matter. In addition, the moisture of the dry matter can be classified into being present inside the cell of the dry matter and present in the outer wall of the cell. The moisture present in the outer wall of the cell can be removed relatively easily through a process such as dehydration. Since the moisture present inside is made through the cell wall, there are several conditions to be met.
First, the heat of evaporation must be applied from the outside so that the moisture inside the cell can evaporate. Second, the condition that the saturation vapor pressure is large is required by reducing the external moisture content than the moisture content inside the cell.
Methods for providing the above conditions include heating, ventilation, dehumidification, decompression, etc. Among these, heating is a means for conducting heat to the dry matter to vaporize the water in the body, and decompression lowers the boiling point of the water to lower the cell temperature. It is a method of boiling and evaporating moisture inside, and ventilation is a method of equilibrating the density of moisture between the inside of the cell and the air.
The decompression is a method of increasing the variation of the saturated vapor pressure inside and outside the cell and lowering the boiling point of water to induce rapid evaporation. Dehumidification is also a method of increasing the evaporation rate by increasing the variation of the saturated vapor pressure.
Therefore, having all these listed conditions is how to make a good quality building, but it is difficult to meet the conditions of decompression at the production site.
As the drying method described above, various methods such as natural drying, reduced pressure drying, low temperature drying, freeze drying, and high temperature drying are used.
The natural drying refers to drying in the sun and wind, which is naturally obtained solar energy.
However, such a natural drying method is a slow drying rate, and also subject to a lot of restrictions due to external conditions such as rain, it is intended to solve this problem under reduced pressure drying, low temperature drying, freeze drying, high temperature used in a general factory, etc. Drying and the like have been proposed.
Among the drying methods are reduced pressure drying or freeze drying. The reduced pressure drying refers to a method of drying the dried product in a pressure reducer, etc., and the freeze drying refers to a drying method of freezing and drying the dried product at the same time as drying.
The reduced-pressure drying and freeze-drying can obtain a good quality product, but in order to realize this, expensive facilities such as a pressure reducer and a freezer are required.
Therefore, in view of this point, the most commonly used drying method is a drying method by heating. However, the heat drying also requires a lot of energy costs, and excessive heating in the heat drying method causes the protoplasts of the dry matter to expand, resulting in a change in the form of the material contained in the cells due to cell rupture, thereby making it impossible to obtain a high quality dry matter.
In addition, in order to facilitate drying, a dehumidification effect of removing moisture from the air introduced is very important. In order to achieve such dehumidification, a conventional dehumidifier uses a refrigeration compressor or the like to reduce the cooling fins and pass wet air therethrough. A simple dehumidification method has been used, but this dehumidification method is not suitable for a process that assumes drying.
The present invention solves the problems of the conventional drying method described above.
That is, it is an object of the present invention to provide a highly efficient and multifunctional drying apparatus for heating the dehumidified air obtained by exerting the optimum dehumidifying effect in the air flowing into the outside in an optimal state.
Another object of the present invention is to provide a multifunctional dry dehumidifying apparatus which can be realized at a low cost and a facility without the need for the above-described reduced pressure drying and freeze drying.
In addition, another object of the present invention is to reduce the cost of energy in the above-mentioned heat drying method generally used most widely, and in particular, to obtain a high-quality dry material that does not destroy the protoplasm of the dry object by excessive heating It is to provide a dry dehumidifier.
Further, another object of the present invention is to provide a multifunctional dry dehumidifying apparatus which removes harmful microorganisms inhabiting a dry matter, while providing a deodorizing means for removing odor generated in a drying process.
In order to achieve the above object, the present invention includes the following means.
That is, the dehumidifying and drying apparatus of the present invention includes one or more cooling plates for dehumidifying condensation of moisture contained in the air introduced therein, one or more heat sinks for heating the dehumidified air, and one attached between the cooling plates and the heat sinks. And a blower for discharging the heated air.
As described above, in the dehumidifying and drying apparatus of the present invention, a process of dehumidifying the introduced air with the cooling fins is performed, and the dehumidified air is heated by the heat sink. In addition, since the thermoelectric element is attached to the cooling plate and the heat sink at the same time, the heat source for cooling and heating is used as the single source of the thermoelectric element, thereby providing excellent thermal efficiency.
In addition, in the dehumidifying drying apparatus of the present invention, the thermoelectric element is structurally formed in a thin thin plate shape, and is very easy to attach the cooling plate and the heat sink to both sides, and the heat generated in the reversible reaction is generated in the cells of the dry matter. It is used as a means of replenishing the lost heat, which enables precise and effective dehumidification with low power compared to the cooling method by the conventional refrigeration compressor.
In addition, in the dehumidification drying apparatus of the present invention, in order to reduce energy consumption, the present temperature and humidity are measured to reflect the specifications in the cooling system to control the temperature.
In addition, the dehumidifying drying apparatus of the present invention includes an ultraviolet lamp for applying titanium dioxide to the surface of one of the one or more heat sinks and irradiating ultraviolet rays to the coated surface.
In the dehumidifying and drying apparatus of the present invention, all the power supply devices are arranged at the rear end of the heat sink, with the cooling plate and the heating plate as the boundary.
Moreover, the dehumidification drying apparatus of this invention forms the shape of the said cooling plate and a heat sink in a chevron shape, and sets it as the formation for trapping the air which injects at least one part of the said cooling plate and a heat sink.
That is, in the dehumidifying and drying apparatus of the present invention, the cooling plate can be effectively dehumidified only if the contact efficiency with the incoming air is high, and for this purpose, the structure of the cooling plate has a V-shaped Sevron shape.
In addition, in order to prevent re-evaporation of water droplets condensed on the cooling plate, pocket-shaped protrusions for trapping air are installed in the bent portion of the plate-shaped cooling plate so that the condensed droplets are collected. Effective dehumidification is achieved by allowing water droplets to flow down.
Cooling of the thermoelectric element must be sufficient heat dissipation at the hot junction, the plate-shaped heat sink attached to the hot junction is also formed in the Severon shape, the heat sink is a structure that is radiated by cold air from which moisture is removed. Further, photocatalyst titanium dioxide is applied to the surface of at least one portion of the heat sink, and ultraviolet rays including 184 nm are irradiated with an ultraviolet lamp. Therefore, the photocatalyst titanium dioxide oxidizes the odor component by ultraviolet rays by the ultraviolet lamp and makes it harmless, and generates a small amount of ozone to destroy the cell envelope of the dry matter to help release moisture inside the cell, Sterilize suspended pathogenic microorganisms to prevent rot and deterioration in advance.
Further, in the dehumidifying drying apparatus of the present invention, the dew point temperature is calculated by installing a temperature and humidity sensor at the external air inlet, and the calculated value is provided to the power supply of the thermoelectric element to control the supply current so that the appropriate dew point is maintained.
In addition, in the dehumidification drying apparatus of the present invention, a control unit is installed, and the control unit measures the amount of condensation and discharged water, obtains humidity data in the air from the temperature and humidity sensor, and determines whether the dry object is dried in an appropriate state. To operate.
As described above, the dehumidifying drying apparatus of the present invention provides a highly efficient multifunctional dehumidifying drying apparatus which heats the dehumidified air obtained by exhibiting the optimum dehumidifying effect in the air flowing into the outside in an optimal state.
Moreover, in the dehumidification drying apparatus of this invention, it can implement at low cost and a facility, without the need for pressure reduction drying, freezer, etc. which are necessary for pressure reduction drying and freeze drying mentioned above.
That is, in the dehumidification drying apparatus of the present invention, by installing the thermoelectric element, the dehumidification and heating are simultaneously performed by using the reversible reaction cooling and heating effect, thereby eliminating the need for a dehumidifier, a freezer, and the like. The facility realizes dehumidification drying.

Here, as described above, in drying the dry matter, the incoming air contains a large amount of moisture, and the function of dehumidification to remove such moisture plays a significant role in the drying process.
The function of the dehumidification will be described in more detail as follows.
A good drying method using less energy is a method of bringing the dehumidified air into continuous contact with the dry matter, which is a method of performing effective drying by supplementing the energy lost in the dry matter through the evaporation process.
This dehumidification is achieved by condensing and removing moisture in the air.
In general, the humidity in the air is divided into absolute humidity and relative humidity, where the concentration of the relative humidity is determined by the temperature, and expresses the ratio of the actual amount of water vapor to the amount of saturated water vapor at a given temperature as a percentage. In addition, saturated water vapor pressure is water vapor pressure when the maximum water vapor is included at a given temperature, and the relative humidity = (current water vapor pressure / saturated water vapor pressure) * 100 is calculated. Therefore, relative humidity at a specific air temperature is used as a basis for predicting the dew point, Table 1 below shows the relationship between the air temperature and the dew point according to the relative humidity. That is, Table 1 is the air temperature value and the relative humidity value measured in the drying chamber is used as the basic data to control the temperature of the dehumidifier cooling fin to an appropriate value, the dew point temperature measurement is a basic for reducing the cooling energy consumption more than necessary It is used as a resource.
In Table 1, -5 ° C, 0 ° C, 5 ° C .. ... displayed horizontally indicates the temperature of the air, 90%, 80%, ... of the vertical indicates the value of the relative humidity, The value of the part intersected by the temperature of the air and the relative humidity immediately represents the dew point.
For example, in Table 1 below, when the air temperature is 40 ° C and the relative humidity at 90%, the dew point is 38.2 ° C, but the dew point drops as the relative humidity decreases due to dehumidification to remove moisture. When the relative humidity reaches 50%, the dew point drops to 27.1 ° C. When the relative humidity reaches 30%, the dew point drops to 18 ° C.
In this way, in order to control the appropriate relative humidity, it is necessary to adjust the temperature of the air.
In addition, when the relative humidity is lowered when the temperature does not change, the difference in the saturated steam pressure of the air becomes larger, so that the drying speed is faster.
However, the evaporation energy is required for the liquid to evaporate inside the cell, and a separate heating means is required to compensate for the consumption of energy during evaporation. Temperature can be maintained.
If the amount of heat supplied exceeds the amount of heat consumed, the temperature gradually rises, and the difference in saturation of water vapor in the air increases. Therefore, since the amount of water vapor required for saturation should also be increased, the moisture in the plant material is easily evaporated and the drying speed is increased. The more moisture is evaporated in the plant, the higher the humidity in the air.
In addition, the larger the flow rate of air, the faster the evaporation of moisture on the surface of the cell, the faster the flow rate of the air to quickly transfer the heat in the air to the dry to maintain the heat of evaporation. In addition, by quickly capturing and evaporating the moisture evaporated from the plant, fresh unsaturated air is quickly replenished to accelerate the evaporation of water on the surface of the plant. In general, the moisture evaporation rate is generally directly proportional to the wind speed in the wind speed range of 3 m / sec or less.
In addition, under normal pressure, the air pressure inside the cell and the outside air pressure are in equilibrium, so that the moisture in the cell evaporates relatively slowly, causing external diffusion. However, after such equilibrium is destroyed, the evaporation rate of the material that can be easily evaporated inside the cell is increased, the external diffusion is also accelerated, and the air pressure inside and outside the cell moves in the equilibrium direction to accelerate the drying speed. Using this principle, a method of accelerating the drying speed may be used by putting it under reduced pressure.
In addition, the cell and tissue structure is an important factor affecting the drying rate, the plasma membrane is dehydrated, contracted gradually by moisture osmosis while the cell membrane is preserved at room temperature, low temperature, and freeze drying, and the dehydration by the action of the cell membrane It slows down and slows down drying.
However, when the temperature rises to a certain portion in the heat drying, the plasma expands and the cell membrane is ruptured, which allows the material to dry faster than room temperature drying.
In addition, the primary cell wall of the dried material to be dried is relatively thin and the structure of the solid is relatively poor and the water content is high, so that the retention of moisture is relatively low. The solid arrangement is relatively dense, which has a certain inhibitory effect on water diffusion, resulting in a slower drying rate.
Principles such as relative humidity and temperature of air described above are fully understood and applied in the present invention, and are reflected in creating a more efficient drying technique.

Next, referring to FIG. 2, titanium dioxide is coated on at least one
The titanium dioxide receives photon energy to generate OH radicals, and the OH radicals have higher oxidation potential than ozone or hydrogen peroxide to oxidize most organic materials and convert them into water and carbon dioxide.
The titanium dioxide has the advantage of being biologically or chemically inert, stable to photo- or chemical corrosion, and decisively inexpensive.
In addition, the photocatalytic activity of the oxide semiconductor is TiO 2 (anatase)> TiO 2 (rutile)> ZnO> ZrO 2> SnO 2> V 2 O 3.
In general, when light is irradiated to a semiconductor, photons (hν≥Eg) having energy above the band gap of the semiconductor are absorbed to cause electronexcitation from the common band to the conduction band, where holes are formed in the shared band. In the conduction band, electrons are generated, which is called electron-hole pair generation, and the generated electron-hole pairs act on water molecules to generate OH radicals. And oxidize almost all materials.
Semiconductors with large band gaps, such as titanium dioxide, absorb only short wavelengths of light and do not absorb visible light.
The ultraviolet lamp used in the present invention is a water-sealed ultraviolet lamp that emits 184 nm and 254 nm. The ultraviolet light of 184 nm dissociates oxygen molecules in the air to generate ozone, and the released ozone is a microorganism inhabiting the cells of the dry matter. Sterilizes and damages the cell wall, helping to evaporate moisture.
