Far infrared ray food dryer {FAR INFRARED RAY DRYER}

The present invention relates to a far-infrared ray food dryer, and more specifically, by placing a far-infrared ray heater rod inside the main body in a longitudinal direction, which is the arrangement direction of the tray, to evenly irradiate the radiated far-infrared ray to all trays and forcibly circulate heat inside the body. It increases the drying efficiency of each object to be dried inside the body, and increases the amount of far-infrared rays irradiation to the object to be dried in the tray as it has a reflecting plate inside the body and the tray is made of a material capable of reflecting far-infrared rays. It relates to a far-infrared food dryer to further increase.

In general, far-infrared rays are a kind of electromagnetic wave that has a longer wavelength than infrared rays and has a large thermal action.When the human body is exposed to far-infrared rays due to its strong absorption and penetrating power when reaching an object, the far-infrared rays penetrate deep into the skin to create heat. This thermal action is known to have an action to eliminate bacteria that cause various diseases, and to expand capillaries to help blood circulation and the creation of cell tissues. Therefore, due to the various effects of far-infrared rays on the human body, many kinds of products for using far-infrared rays in daily life are on the market.

On the other hand, in products using such far-infrared rays, dryers for artificially drying various agricultural and marine products such as peppers, radish, mushrooms, ginseng, medicinal herbs, dried persimmons, shrimp, anchovies, etc., are known. Dryers are well known in which a tray is opened in layers to arrange the objects to be dried, and direct or indirect heat is applied to dry them.

These dryers have multi-stage trays for hanging objects in the dryer enclosure, and include a hot air fan, electric heater, petroleum burner, and controller, so that the high-temperature heat heated by an electric heater or petroleum burner inside or outside is converted into a hot air blower. It is a method of forced circulation and drying. These bulk-type dryers dry agricultural and marine products by continuously discharging the high-temperature and high-humidity air generated during drying to the outside and introducing fresh air from the outside again to apply heat.

1 to 11, a far-infrared food dryer 100 according to an embodiment of the present invention includes a body 110, a far-infrared heater rod 120, and a hot-air circulation guide 130.

The main body 110 forms the outer shape of the far-infrared food dryer 100 according to the present invention. In particular, the main body 110 includes a drying chamber 111 so as to be stored therein to dry the object to be dried, and a door 112 that can open and close its front so that the object to be dried can be put into or taken out of the drying chamber 111.

In addition, the main body 110 is provided with a tray 114 in the drying chamber 111 to place the object to be dried. At this time, the tray 114 is arranged to be spaced apart at a set interval along the height (longitudinal) direction of the main body 110. Of course, the tray 114 can be deformed into various shapes.

In addition, the main body 110 has an inlet 116 to allow the inflow of outside air, and the door 112 has an outlet 118 to allow the moisture vapor generated in the object to be discharged during the drying process. Of course, the outlet 118 may be formed in the body 110.

The main body 110 includes a filter 117 to purify the outside air introduced through the suction port 116. The filter 117 can be applied in various ways, and is detachably installed on the main body 110 in various ways.

Meanwhile, the far-infrared heater rod 120 generates heat when power is applied from the outside and emit far-infrared rays and heat, respectively, and is provided so as to be erected in a longitudinal direction inside the drying room 111, and a plurality of trays arranged in the longitudinal direction ( 114) Far-infrared rays can be evenly irradiated throughout. At this time, it is assumed that a plurality of far-infrared heater rods 120 are provided in the storage chamber 111 of the main body 110.

In particular, a plurality of far-infrared heater rods 120 may be disposed on both sides of the drying chamber 111, respectively. For convenience, it is assumed that the far-infrared ray heater rod 120 is erected in the center of both inner sides of the body 110 provided with the door 112 as a reference. Of course, the far infrared ray heater rod 120 may be fixedly installed on the main body 110 in various ways.

Since the far-infrared heater rod 120 is provided to be erected along the arrangement direction of the tray 114, the object to be dried contained in each of the trays 114 is exposed to far-infrared rays uniform from both sides by the facing far-infrared heater rods 120.

Of course, the far-infrared ray heater rod 120 can be deformed into various shapes.

In addition, the far infrared ray heater rod 120 emits heat. This heat circulates inside the drying chamber 111 and increases the temperature of the outside air introduced through the suction port 116. To this end, a hot air circulation guide 130 is provided.

The hot-air circulation guide 130 serves to evenly transmit the heat radiated from the far-infrared ray heater rod 120 throughout the tray 114 while inducing circulation in the drying chamber 111.

Accordingly, the entire object to be dried contained in the tray 114 receives far-infrared rays and heat together, thereby maximizing drying efficiency and shortening the drying time.

In detail, the hot air circulation guide unit 130 includes an inner lower panel 132, an inner upper panel 134 and a blower 136.

The inner lower panel 132 is provided over the entire inner upper side of the main body 110. Thus, the interior of the main body 110 is divided into a drying chamber 111 at a lower portion and a space at an upper portion based on the inner lower panel 132. In addition, the inner lower panel 132 forms a first circulation induction tool 133a and a second circulation induction tool 133b to circulate the heat of the drying chamber 111. For convenience, outside air and heat flowing from the body 110 to the upper portion of the inner lower panel 132 are supplied to the drying chamber 111 through the first circulation induction tool 133a, and the heat inside the drying chamber 111 2 It is assumed that it circulates to the upper part of the inner lower panel 132 through the circulation induction tool 133b.

In addition, the inner upper panel 134 is provided on the upper side of the inner lower panel 132 inside the main body 110 to form a sealed space 135 between the inner lower panel 132 and the inner lower panel 132. So, heat is supplied from the closed space 135 to the drying chamber 111 through the first circulation induction tool 133a, and from the inside of the drying chamber 111 to the closed space 135 through the second circulation induction tool 133b. As it flows, the degree to which heat is reduced by the closed space 135 is reduced.

The inner upper panel 134 forms an outside air inlet 133c to guide the outside air introduced through the suction port 116 formed in the main body 110 to the drying chamber 111 through the closed space 135.

Of course, the first circulation induction tool (133a), the second circulation induction tool (133b), and the outside air inlet (133c) are not limited to the number, size, and shape.

The blower 136 is provided on the inner upper panel 134. Thus, durability is increased as the blower 136 is not directly exposed to heat.

The blower 136 forcibly guides the heat inside the closed space 135 and the outside air toward the first circulation induction tool 133a, so that the heat inside the drying chamber 111 naturally passes through the second circulation induction tool 133b. It is introduced into the closed space (135).

At this time, the blower 132 and the first circulation induction tool (133a) is a closed cover so that the blower 132 can guide the intensive flow of the heat inside the closed space 137 and the outside air toward the first circulation induction tool (133a). It can be connected to (139).

Further, the upper part of each of the far-infrared heater rods 120 is inserted into the inner lower panel 132 and supported by the inner lower panel 132. In particular, the sealing cover 139 covers the far-infrared heater rods 120 that are inserted and supported on both sides of the inner lower panel 132, and the heat and outside air cover the first circulation induction tool (133a) and the second circulation induction tool (133b) It serves to allow flow only through. Of course, the sealing cover 139 can be deformed into various shapes.

In addition, as the wet air inside the drying chamber 111 of the main body 110 is discharged through the outlet 118 of the door 112, the main body 110 has a suction port 116 in order to allow outside air to flow into the closed space 135. ) Is formed, and the outside air introduced through the inlet 116 is guided into the closed space 135 through the outside air inlet 133c of the inner upper panel 134. In particular, since the blower 136 is exposed to the outside air in a state before flowing into the closed space 135, the blower 136 is prevented from being heated by the natural cooling method.

In addition, the inner lower panel 132 may include an angle distribution plate 137 extending downward from the edge of the first circulation induction tool 133a and inclined toward the inner side of the body 110.

The outside air and heat introduced (circulated) into the drying chamber 111 through the first circulation induction tool 133a by the angular spray plate 137 are carried out by the angular dispersion plate 137 along the corresponding main reflecting plate 140. By being transmitted to the bottom of the lower part 111, the heat is transmitted to the object to be dried contained in the lowermost tray 114. Of course, the angle distribution plate 137 is formed in various shapes.

In particular, each of the tray 114 has a through hole 119 through the bottom surface. The heat circulating inside the drying chamber 111 is transmitted to the upper portion of the object to be dried through the open upper side of the tray 114 and transmitted to the lower portion of the object to be dried through the through hole 119. Therefore, the drying efficiency of the object to be dried is further increased. Of course, the number, size, and shape of the through hole 119 can be applied in various ways.

In addition, the main body 110 and the door 112 are provided with a main reflection plate 140 to reflect the far-infrared rays emitted from the far-infrared heater rod 120 toward the tray 114. In this case, the reflector 140 is made of a material having a high reflectance of far-infrared rays, and can be transformed into various shapes.

In addition, each of the trays 114 is mounted on the mounting bracket 115 inside the body 110. That is, in the main body 110, a plurality of mounting brackets 115 are disposed along the axial direction of the far-infrared heater rod 120 on both sides of the far-infrared ray heater rod 120. Thus, the tray 114 can slide in and out while being supported by the mounting brackets 115 corresponding to the lower sides of the tray 114. Of course, the mounting bracket 115 can be deformed into various shapes.

The mounting bracket 115 may be fixedly installed on the inner surface of the main body 110 or may be fixedly installed on the corresponding main reflective plate 140.

In addition, when the heat of the far-infrared ray heater rod 120 is directly transmitted to the object to be dried or directly transmitted to the tray 114, the object to be dried contained on the edge of the far-infrared ray heater rod 120 side of the tray 114 is burned. To prevent this, the sub-reflective plate 122 is disposed around the far-infrared ray heater rod 120 on the tray 114 side.

The sub-reflective plate 122 reflects the far-infrared rays of the far-infrared ray heater rod 120 to the adjacent main reflection plate 140, thereby increasing the reflection angle of the far-infrared rays from the main reflection plate 140 to cover a wide area of the tray 114. It serves to enable research. In addition, it serves to prevent heat from the far-infrared heater rod 120 from being directly transmitted to the tray 114 by being reflected by the sub-reflecting plate 122.

Of course, the sub-reflective plate 122 can be applied in various shapes.

In particular, the circumferential surface of the main body 110 itself may serve as a reflection of far-infrared rays, but the main reflecting plate 140 is spaced apart from the circumferential surface of the main body 110 by a predetermined distance, so that the main body is heated by the heat inside the drying chamber 111. By preventing the circumferential surface of 110 from becoming hot, safety accidents such as burns are prevented.

In addition, the tray 114 may be made of an aluminum material to promote circulation while reflecting the far-infrared heat emitted from the far-infrared heater rod 120. Of course, the tray 114 may be made of various materials whose circumferential surface can reflect far-infrared heat.

As a result, the far-infrared heater rod 120 evenly transmits far-infrared rays and heat to the object to be dried in the tray 114 in the body 110, thereby maximizing the drying efficiency of the object to be dried.

In addition, the inside of the drying chamber 111 of the main body 110 may be provided with an ozone lamp 150 for deodorizing odors generated during the drying process of the object to be dried and sterilizing bacteria therein. The ozone lamp 150 may be installed on at least one of the main body 110, the inner lower panel 132, and the inner upper panel 134. Thus, the heat circulates inside the drying chamber 111 while containing ozone.

In particular, since the far-infrared heater rod 120 is provided in a firmly erected state inside the drying room 111, the far-infrared wavelength is irradiated evenly between the trays 114 stacked in the vertical direction and between the trays 114 and the trays 114 As a result, as the drying time of the object to be dried is shortened due to the circulation of the far-infrared wavelength and heat, it is possible to quickly dry the object to be dried at a lower temperature than before, so that the nutrients of the object are less destroyed.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is only illustrative, and those of ordinary skill in the field to which the technology pertains, various modifications and other equivalent embodiments are possible. I will understand. Therefore, the true technical protection scope of the present invention should be determined by the following claims.
