BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LED substrate having a near-

The present invention relates to a method and apparatus for preventing the destruction of cell membranes during the drying process of agricultural and marine products, the storage of vaporizable substances in agricultural and marine products, the dissipation of near infrared rays that preserve the nutrient protection and flavor of agricultural and marine products, And an LED substrate having a near infrared ray diverging function for drying agricultural and marine products, which prevents deterioration.

Conventional methods for drying agricultural products such as red pepper and anchovy include sun drying, house and polyethylene film coating drying, thermal drying, hot air drying, and cold air drying. However, both of the former methods require a long time to dry agricultural and marine products , And the rate of corruption was also high, which was not practical.

In this method, hot air drying is a method of evaporating moisture of a material by blowing hot air into an airtight space. Since hot air drying directly applies high temperature to the dried material, nutrient destruction is high, and the state of the dried material becomes flat, Drying efficiency was significantly lower than that of red pepper seeds.

In the thermal power drying, the temperature in the dryer is raised by using an electric heater, a fired heater directly burning and heating gas or oil, etc., and the moisture in the dried material is evaporated using a high temperature air and a blower in the drying apparatus However, the evaporated moisture is discharged out of the dryer together with the air in the drying apparatus, and the dried material is dried. The most widely used means for generating thermal power in thermal drying is an electric heater with a simple temperature control in the dryer. However, electric heaters have contributed greatly to the power surge in summer due to excessive electricity use. In addition, there is a disadvantage that the color of the dried material is considerably lower than that of natural drying when the drying is performed in an enclosed space. Furthermore, thermal power generation using a combustion heater is avoided in dry countries in advanced countries due to the seriousness of the global warming problem caused by carbon dioxide gas.

In recent years, in order to overcome the problems of the conventional dryer described above, development of environmentally friendly alternative fuels such as biofuels is progressing, and a drying LED chip technology which has the maximum drying effect with minimum power has been developed.

However, the dryer using the conventional drying LED chip merely merely thermal-drying the drying target agricultural and marine products using the heat generated incidentally at the time of the light generation, and the color of the drying agent is changed by the general light including the visible light of the LED chip, The conventional LED chip drier minimizes the power loss consumed in the drying process, and the drying effect of the agricultural and marine products is not so different from that of the heating type dryer such as the electric heater.

In addition, the LED chip installed on the inner wall of the drying chamber of the large dryer has formed an LED substrate structure in which a large number of LEDs are assembled on a substrate basis. However, the LED substrate had to be manufactured in various forms according to the area and shape of the inner wall of the drying chamber to be installed. In addition, since the LED substrate is installed so as to cover the inner wall of the drying chamber, moisture in the drying chamber, which is increased due to the humidity of the agricultural and marine products having humidity, seeps between the LED substrate and the inner wall of the drying chamber, .

As a result, the conventional LED chip has less drying efficiency than the heating type dryer, and thus the LED chip has not received a favorable response in the agricultural and marine products dryer business field.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, It will be possible. The present invention is capable of various modifications and various forms, and specific embodiments are illustrated in the drawings and described in detail in the text. It should be understood, however, that the invention is not intended to be limited to the particular forms disclosed, but on the contrary, is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view schematically showing a dryer provided with an LED substrate according to the present invention, and FIG. 2 is a block diagram showing the structure of the dryer shown in FIG. 1, and will be described with reference to FIG.

The LED substrate of this embodiment is installed in a dryer 100 equipped with a drying chamber for drying objects such as agricultural and marine products. Hereinafter, the dryer 100 will be briefly described. Referring to FIG. 1, the dryer 100 includes a housing 110, a LED substrate 120 for radiating radiant light in a near infrared range, and a suction fan 130 for forcibly introducing air into the drying chamber. A sensor for sensing at least one of a temperature, a humidity and a brightness of the inside of the drying chamber; a sensor for sensing the amount of light emitted from the LED module 120 and the suction fan 130; The switch 160 for controlling the operation intensity of the exhaust fan 140 and the ON and OFF of the exhaust fan 140 and the ON and OFF states of the LED substrate 120, the intake fan 130 and the exhaust fan 140, And includes a controller 170 for controlling the switch 160 to control the intake fan 130 and the exhaust fan 140.

The housing 110 forms an isolated drying chamber which constitutes a space in an environment different from the external environment. In addition, a door (not shown) for opening and closing the drying chamber is formed in the housing 110 to allow the agricultural and marine products to be dried into and out of the drying chamber. Subsequently, the housing 110 of the present embodiment includes a partition 110 'for the compartment of the drying chamber. A plurality of partition walls 110 'may be formed to form a plurality of spaces in the drying chamber. On the other hand, for smooth ventilation in the comparted drying chamber, the partition wall 110 'is provided with an intake pipe, and at each position of the partition 110', a ventilation opening 111 for opening the intake pipe is formed.

The LED substrate 120 includes a near-infrared LED 121 that emits radiation in the near-infrared range. Conventional dryers with LEDs are merely expecting economical effects that the power consumption of LEDs is low, and LEDs, such as electric heaters and heating type dryers such as combustion heaters, Function. However, the LED substrate 120 according to the present invention does not dry the agricultural and marine products as heat. In the process of drying the agricultural and marine products with the near-infrared rays emitted by the near-infrared LED 121 and operating the LED substrate 120 to irradiate the radiation, The incidental heat is merely to heat the temperature inside the drying chamber. For reference, thermal drying of agricultural and aquatic products causes destruction of cell membranes of agricultural and marine products, destruction of nutrients and loss of flavor, while the drying of near infrared rays according to the present invention significantly reduces cell membrane destruction and maintains nutrients and flavor. Therefore, the near infrared ray drying according to the present invention is expected to provide a drying effect similar to natural drying, unlike thermal drying.

The drying effect using the near-infrared LED 121 of the present invention will be described in more detail. Since the simple hot air method has a limitation in the uniform energy transfer, the drying object has a browning phenomenon frequently. However, The browning phenomenon is very insufficient. In addition, the flavor of the agricultural and marine products is greatly reduced due to the vaporization of the food ingredient due to damage to the cellular tissues of agricultural and aquatic products caused by the general hot air drying process, and the flavor comparable to that of the natural light dried food can be expected. In addition, since the microbial killing effect for enhancing the shelf life of dried food is far superior to the near-infrared drying method, the dry food of the dried agricultural and fishery products of the present invention can greatly increase the storage period and improve the hygiene.

The wavelength of the light emitted by the near-infrared LED 121 of this embodiment is 700 to 1500 nm, preferably 700 to 950 nm, and the output is 0.1 to 3.0 W, which is the near infrared ray wavelength band.

The LED substrate 120 may include an ultraviolet LED 122 for sterilizing agricultural and marine products to be dried as well as for sterilizing the inner wall of the housing 110. Since the germicidal function of the ultraviolet rays emitted by the ultraviolet LED 122 is a well-known technology, a detailed description of ultraviolet rays is omitted here.

The LED substrate 120 of the present embodiment may further include a red light LED 123 emitting red light. The red light of the red light LED 123 allows the user to visually confirm whether the dryer 100 is operating. The red light LED 123 of the present embodiment emits light having a wavelength of 630 nm which is a range of a red wavelength, but is not limited thereto.

As described above, the LED substrate 120 includes a near-infrared LED 121 and, in addition, an ultraviolet LED 122 or a red light LED 123. [ The LED substrate 120 may be installed on the inner wall of the housing 110 and the partition 110 'to provide a drying environment inside the drying chamber, or may be installed in a separate container. A more detailed description of the LED substrate 120 according to the present invention will be described below with reference to embodiments.

The suction fan 130 and the exhaust fan 140 perform ventilation of the inside of the drying chamber of the housing 110. To this end, the intake fan 130 is installed at the intake port of the housing 110, and the exhaust fan 140 is installed at the exhaust port of the housing 110. An exhaust pipe 141 for exhausting the exhaust fan 140 can be connected to the exhaust port of the housing 110. Although not shown in the drawing, an intake pipe (not shown) for inserting the intake fan 130 is provided in the intake port of the housing 110 ) Can be piped. Although the suction fan 130 and the exhaust fan 140 of this embodiment are located at the lower end of the drying chamber, it is preferable that the suction fan 130 and the exhaust fan 140 are disposed at positions where the air circulation inside the drying chamber efficiently occurs.

The dryer 100 of the present embodiment includes both the suction fan 130 and the exhaust fan 140 but may constitute only one of the suction fan 130 and the exhaust fan 140.

The sensor senses the brightness, humidity and temperature of the drying chamber. To this end, the sensor includes a temperature sensor 151 for sensing the temperature of the drying chamber, an optical sensor 152 for sensing the brightness, and a humidity sensor 153 for sensing the humidity. Although the sensor of the present embodiment includes both the temperature sensor 151, the optical sensor 152, and the humidity sensor 153, it may include at least one or more of them.

The switch 160 adjusts the amount of light emitted from the LED module 120 under the control of the controller 170 and at the same time controls the operation intensity and the ON and OFF of the intake fan 130 and the exhaust fan 140.

The controller 170 controls the operation of the dryer 100 according to a user's operation and receives a sensing signal from the sensor and turns on and off the LED board 120, the intake fan 130 and the exhaust fan 140 OFF automatically.

FIG. 3 is a perspective view showing an embodiment of the LED substrate according to the present invention, and FIG. 4 is a plan view showing a plan view of the LED substrate shown in FIG. 3 (a).

3 (a), the LED substrate 120 of the present embodiment includes a plurality of near-infrared LEDs 121 mounted on a circuit board 124 to constitute one set, and the circuit board 124 Are arranged side by side so as to form through holes (S), and both ends are integrally connected by a pair of coupling bars (125). Here, the circuit board 124 is provided with a hydrophobic coating on the circuit board 124 so as to prevent the occurrence of leakage or short-circuiting or corrosion due to moisture generated during drying of drying objects such as agricultural products desirable. For reference, the hydrophobic coating is performed by performing atmospheric pressure plasma treatment on the surface of the inner reflection film and the drying table so as to exhibit strong hydrophobicity. Thus, the surface of the circuit board 124 has moisture removal effect and light reflection effect.

As a result, the LED substrate 120 of this embodiment exhibits a function as a planar light source while forming a plate shape in which the through hole S is formed. The through hole S serves as a vent hole passing through the LED substrate 120 so that the heat of the circuit board 124 itself generated during the light emission of the near infrared LED 121 is cooled, Near-infrared rays for irradiating a drying object at a portion to be covered by another site can be irradiated through the through-hole S. In addition, the through hole S minimizes the moisture generated by covering the predetermined area of the inner surface of the drier in order to form the surface light source of the LED substrate 120, thereby allowing the LED substrate 120 to operate in an electrically stable manner without generating sparks .

In the LED substrate 120 of the present embodiment, a plurality of near-infrared LEDs 121 are regularly arranged in line between the through-holes S, but may be irregularly arranged in multiple rows. On the other hand, the circuit board 124 of the LED substrate 120 can mount the red LED 123 in addition to the near-infrared LED 121. The red light LED 123 blinks together with the near infrared ray LED 121 so that the user can visually recognize whether the near infrared ray LED 121 that can not be seen is turned on. In addition, the ultraviolet LED 122 may be further reinforced to sterilize the inside of the drying chamber or the drying target agricultural product. However, the ultraviolet LED 122 may be installed separately at one point in the drying chamber without being mounted on the circuit board 124 of the LED substrate 120.

The LED substrate 120 is formed with a plug 126 for applying electricity to the LED of the circuit board 124 and the plug 126 is inserted into the socket 126 ' In this embodiment, it is preferable that the outlet 126 'is connected to the electric wire W for each outlet 126' so as to minimize positional restriction of the LED substrate 120. Since the plug 126 can be smoothly inserted and removed from the socket 126 ', the plug 126 can be replaced in units of the LED substrate 120 in the dryer, thereby facilitating maintenance and management of the dryer 100. The positions of the plug 126 and the socket 126 'may be changed with each other, and hereinafter referred to as a connector CO.

For reference, the size of the LED substrate 120 shown in FIG. 4 is merely an example, and other sizes of deformable designs are possible.

As shown in FIG. 3 (b), the LED substrate 120 'of the present embodiment is a set of a plurality of circuit boards 124' connected in series. In this embodiment, the circuit board 124 'has a rectangular shape or a long circular shape, and the neighboring circuit board 124' is mechanically and electrically connected via the electric wire W '. A connector 126 '' for energizing the external electric wire W is formed on the circuit board 124 'located in the terminal. As a result, the LED substrate 120' of the present embodiment has a long structure Respectively.

The LED substrate 120 'of the present embodiment can be installed in a congested section or a narrow section where the LED substrate 120' shown in FIG. 5 (a) can not be arranged, and the near infrared rays It enables effective investigation.

3, the near infrared LED 121 is not provided on the inner wall of the housing 110, but the LED substrates 120 and 120 ', which are a set of a plurality of LEDs 121, ) Can be installed. Therefore, when there is a problem in the operation of the near-infrared LED 121 or when the inside of the drying chamber 100 is cleaned, the LED substrates 120 and 120 'can be easily removed.

For reference, the circuit board 124 of the LED substrate 120 is preferably made of a material that does not deform even at 60 to 70 ° C and does not generate harmful substances, and uses lead-free solder for mounting the LED 121.

FIG. 5 is a block diagram illustrating a wiring pattern for each LED constituted on the LED substrate according to the present invention. Referring to FIG.

The LED substrate 120 of this embodiment electrically connects a plurality of near-infrared LEDs 121 mounted on the circuit board 124 electrically in parallel. Therefore, even if there is a problem with any of the near-infrared LEDs 121 of the plurality of near-infrared LEDs 121, the neighboring other near-infrared LEDs 121 normally turn on. At least one of the ultraviolet LED 122 and the red LED 123 may be reinforced together with the near-infrared LED 121 and electrically connected in parallel with the near-infrared LED 121.

5 (b), the ultraviolet LED 122, which is different from the drying function of the near-infrared LED 121, is separated from the channel of the near-infrared LED 121, So that the blinking can be separated. In the present embodiment, the near-infrared ray channel connector CO 'and the ultraviolet ray channel connector CO' are separated for channel separation. However, two channels of electric wires may be connected to one connector.

FIG. 6 is an exploded perspective view showing another embodiment of the LED substrate according to the present invention, and FIG. 7 is an enlarged view of the X portion of FIG.

The LED substrate 120 according to the present invention allows the assembly of the circuit boards 124 to be adjusted so that the number of the circuit boards 124 can be adjusted according to the situation where the LED board 120 is installed.

To this end, the LED substrate 120 of the present embodiment is formed such that the pair of coupling bars 125 'and 125' 'are paired with the circuit board 124 so that one pair of the coupling bars are connected to both ends of the circuit board 124, ) Between the binding bars 125 'and 125 "in accordance with the number of the binding bars 125' and 125 ".

And a magnetized body 125g of a magnetic material such as iron is formed around the second connection cord 125f by the magnetic force of the magnetic body 125b, The magnetization body 125g is dragged by the magnetic force of the magnetic body 125b and the second connection cord 125f can be easily connected to the first connection cord 125a when the second connection cord 125f is adjacent to the cord 125a .

Since the connecting bars 125 'and 125 " according to the present embodiment are connected or disconnected as required, the electrical connecting sections such as the first and second connecting cords 125a and 125f must be exposed to the outside, In order to minimize external exposure of the first and second connection cords 125a and 125f connected to each other and to provide insulation, the first and second connection cords 125a and 125f may be exposed to the circumference Shaped plugers 125c and 125h that surround the first and second connecting cords 125a and 125f can be reinforced. In a state where the first and second connecting cords 125a and 125f are connected to each other, a stable energized state is maintained without a short circuit or a short circuit.

The connecting bars 125 'and 125''of the present embodiment are configured such that one side thereof is integral with or detachable from the circuit board 124.
