 The present invention relates to a bulk-type far-infrared dryer, and more specifically, to install a far-infrared radiation plate in which far-infrared wavelengths can be emitted through direct electric energy or indirect hot air supply between the cabinets mounted in multiple stages in the drying chamber. In addition, a heat recovery device having a dehumidification means for recovering, dehumidifying the waste heat discharged from the drying chamber and supplying it back to the dryer, a moisture exhaust fan for primarily discharging the humid air generated at the beginning of the drying operation, and the heat recovery. Hot air supply duct with multi-stage hot air supply nozzle is applied to supply hot air discharged from the device between each tray and far-infrared radiating plate. It is possible to improve the flavor of the dry matter and remove odor, as well as long-term From, in, it can also reduce the dependence of the drying when hot air through the effect of far-infrared rays can be pursued in the advanced quality with low temperature drying may be one to pursue energy saving due to the shortening of time to dry.

In general, infrared rays are a kind of electromagnetic waves with a longer wavelength and a greater thermal effect than the red region of visible light.

Infrared rays in the region with long wavelengths within this infrared wavelength range are called Far Infrared Rays. Far infrared rays are longer than infrared rays. Due to the far infrared rays in the human body, heat penetrates deeply into the skin to create heat. This thermal action removes bacteria that cause various diseases and expands capillaries to help blood circulation and cell tissues. It is known to work.

Therefore, due to various effects of the far infrared rays on the human body, many kinds of products for using the far infrared rays in daily life have been released to the market.

On the other hand, products using far-infrared rays such as pepper, radish, mushroom, ginseng, medicinal herbs, dried persimmon, shrimp, anchovy, etc., are known for drying dryers. Bulk-type dryers are well known in which a layer layer is formed inside to arrange dry matters and dry the dry matter by applying direct or indirect heat.

Most known bulk dryers are equipped with multi-stage hooks for hanging dry items in a dryer enclosure, including a hot air fan, an electric heater, a burner and a controller, and are heated by an electric heater or an oil burner internally or externally. It is a method of forcibly circulating high temperature heat with a hot air and drying it, and it is a method of drying agricultural and marine products while continuously discharging the hot and humid air generated inside the dryer to the outside and reintroducing fresh air from outside. .

However, such a conventional dryer continuously discharges the high temperature and high humidity air inside the dryer to the outside, thereby increasing the consumption and waste of thermal energy and inflowing the external air into the dryer without removing moisture contained in the dryer. Therefore, the drying rate is very slow, and especially when the weather is cloudy or rainy, humid air is introduced, causing a burden on the energy cost for heating.

In addition, the drying effect is deteriorated due to forced drying by heat and wind, resulting in deterioration of quality, color discoloration, loss of taste and nutrients, and deterioration of product value due to easy decay or deterioration of dry matters during storage and distribution.

In addition, in the conventional dryer, a structure in which hot air rises from a tray located at the bottom to a tray located at the upper part, that is, the hot air rises and passes through a plurality of trays, has mostly been designed to dry the dried object.

Thus, in a structure in which hot air passes through a plurality of trays from below to dry the dried matters, the drying speed of the dry goods placed on the lower tray is fast and the drying speed of the dry goods placed on the upper tray is slow and uniform. Not only was it difficult to dry, but the drying efficiency was also poor.

The present invention is devised to solve and solve all the problems caused by the existing structure as described above,

The purpose of the present invention is to sterilize the dried products by far infrared rays, which makes it possible to dry more hygienically, to improve the flavor and remove odors of the dried products, and to store them for a long time. It can be lowered to pursue the high quality of the quality through low-temperature drying, and to provide a bulk type far-infrared dryer that can seek energy savings by shortening the drying time,

In order to achieve the above object, the present invention installs far infrared radiation plate through which direct infrared energy can be emitted through direct electric energy or indirect hot air supply between multiple stages installed in the drying chamber and discharged from the drying chamber. A heat recovery device having dehumidification means for recovering and dehumidifying waste heat to be supplied to the dryer, a moisture exhaust fan for primarily discharging humid air generated at the beginning of the drying operation, and hot air discharged from the heat recovery device. It can be achieved by applying a hot air supply duct having a multi-stage hot air supply nozzle to supply transversely between each tray and the far infrared radiation plate,

<Not shown in the drawing>

(C) shows an electrical connector that is optionally applied to a far infrared radiation plate.

If described in detail the operation of the subject innovation is configured as follows.

The shape of the support rail 21 in the present invention is represented in the same manner as the tray hanger (3), and any structure that can be mounted on the flat far-infrared radiating plate 20 stably satisfies any shape and limited to a specific structure Make sure it doesn't work.

In addition, the far-infrared radiation plate 20 is a form in which a sheet-like member capable of emitting far-infrared rays is tightly fixed in a rectangular frame of a conductive material, as shown in FIG. 4, to directly heat the sheet-like member using electrical energy. In this case, as shown in FIG. 4, when the electric connector C is coupled to supply power, and indirectly using only a separate hot wind, only the application of the electric connector C is excluded as shown in FIG. 5. do.

On the other hand, the structure of the heat recovery device 50 is applied to the present invention is known in the present invention is to play a role as a component having one independent function.

The hot air supply nozzle 63 of the hot air supply duct 60 has a long width over the entire width of the vertical portion 62.

The present invention is open the door (6) of the drying chamber (2) and when the operation switch of the dryer is turned on in the state to fill the dry object 3 to be mounted therein, the electrical connector of the far infrared radiation plate 20 Power is applied to (C) to radiate far infrared rays, and at the same time, the heat recovery fan 56 of the heat recovery device 50 is driven.

When the heat recovery fan 56 is rotated, the air in the drying chamber 2 is introduced into the heat recovery unit 50 through the inlet port 51 through the waste heat recovery port 40, and the introduced air is introduced into the electric heater through the exhaust port 53. The air transported to (4) and heated by the electric heater 4 is supplied to the drying chamber 2 through the hot air supply duct 60 again to repeat the process of drying the dry matter, more specifically. Detailed drying process is as follows.

In the drying process of the present invention as described above, at the initial stage of drying, the moisture contained in the dry matter is evaporated to the maximum, so that the air in the drying chamber 2 contains a large amount of moisture. In addition to heat recovery operation, moisture must be discharged and removed as quickly as possible for a certain period of time due to deterioration of the temperature of hot air and excessive consumption of electrical energy, and deterioration of drying efficiency. When the moisture discharge fan 30 is driven by using), the humid air sucked through the suction port 31 in communication with the drying chamber 2 is discharged to the outside of the dryer body 1 through the discharge port 32.

Therefore, the humid air in the drying chamber 2 can be rapidly reduced through dehumidification by forced discharge through the moisture discharge fan 30 together with dehumidification by the recovery of the heat recoverer 50 to prevent temperature reduction of the hot air. It can improve the drying efficiency and block the waste of electrical energy.

On the other hand, when the air introduced into the heat recovery unit 50 through the waste heat recovery port 40 and the connection pipe 52 by the operation of the heat recovery unit 50 hits the filter body 57, most of the moisture turns into water and dehumidifies. Some dehumidified moisture is discharged to the outside through the moisture outlet 54 and heat in the air is stored in the filter body 57 and recovered by the heat recovery fan 56 and at the same time, the air inlet 55 and the filter body ( The air heated by the electric heater 4 is transferred to the electric heater 4 through the exhaust port 53 in a state of being mixed with the outside air introduced in a dehumidified state through a considerable amount of dehumidification through the hot air supply duct 60. Through the hot air supply nozzle 63 through the horizontal portion 61 and the vertical portion 62 of the re-supply to the drying chamber (2) as shown in FIG. 2 and between each tray 3 and the far-infrared radiation plate 20 It is supplied transversely to heat the far-infrared radiation plate 20 and the object to be dried at the same time.

Since the time for moving the hot air to the upper end of the vertical portion 62 is shorter than the hot air is discharged to the supply nozzle 63, it is possible to uniformly heat the front panel 3 and the far infrared radiation plate 20 at the same time. The speed and efficiency of the drying operation can be improved.

On the other hand, in the far-infrared radiation plate 20 which is heated by a power source or by hot air, a unique vibration wavelength is generated to penetrate deeply into the object to be dried, thereby heating the object in addition to the heating of the hot air. Effective drying proceeds.

The present invention as described above, even when the outside air is introduced by the filter body 57, the moisture is dehumidified by a considerable amount, so that only the dried air is introduced, thereby enabling effective drying regardless of the weather and temperature.

On the other hand, the inner wall of the drying chamber 2 of the present invention is provided with a far-infrared coating layer 70 using a far-infrared radiation material having a predetermined thickness, so that it is possible to directly radiate a large amount of far-infrared rays to the building through heating by hot air during the drying process. The far-infrared efficacy is thus directly and abundantly supplied to enable fast drying and high quality dry matter.

In the above, an embodiment of the present invention has been described, but modifications and variations within the scope without departing from the technical spirit of the present invention by those of ordinary skill in the art belong to the scope of the present invention Of course.

As described above, the far-infrared dryer of the present invention is capable of sterilizing the dry matter by the far-infrared rays radiated from the far-infrared radiation plate, which enables more hygienic drying, improves the flavor of the dry matter, removes odors, and also allows long-term storage. Since the effect of far-infrared rays can lower the dependence of hot air in the drying process, excellent drying effect can be expected even at low hot wind temperature.

Through the heat recovery device, the waste heat can be recovered and reused, and the dehumidification function of the inlet air can be used to reduce the drying time and reduce the energy. It is a useful design having the effect of improving the drying rate and drying efficiency of the dried material by making the hot air supply uniform and stable.
