Description

Hot Air Far Infrared Dryer {Far Infrared Ray Dryer by Hot Air}

The present invention relates to a hot-air far-infrared dryer, and more specifically, to the inside of the drying chamber of the conventional hot-air dryer with a ceramic coating to radiate far-infrared radiation by heat caused by hot wind to dry the agricultural products by applying hot air and far-infrared at the same time It is related with the produced hot air far infrared dryer.

In general, drying methods of harvested agricultural products include conventional methods and drying methods using fossil fuels such as oil. Conventional methods have the advantage of being able to receive high prices due to excellent merchandise by maintaining excellent quality by drying in a natural state exposed to sunlight, but has the disadvantage of being limited in terms of climate and space utilization.

Drying method using fossil fuel such as oil refers to a method of drying by generating hot air with heat generated by burning fuel. Although this drying method is widely used and widely used, such a hot air dryer is used for fuel consumption and It is uneconomical due to excessive power consumption, and it is difficult to produce high quality products because the quality is lowered when hot air drying of agricultural and marine products or other products.

In the current drying field, the above-mentioned hot air drying method is mainly used. In the hot air drying method, since the height of the drying system varies depending on the heating material, the heat transfer method by the hot air convection is very low in efficiency, regardless of which method is used. Degradation in quality has been pointed out as a problem.

On the other hand, far infrared rays are radiant energy emitted when the ceramic is heated above room temperature, and emits far infrared rays when heated by another heat source. Therefore, it is possible to radiate far-infrared rays by coating heating far-infrared radiation ceramics on the surface of heat-resistant material in the form of plate, tube, lamp, or coating in accordance with various heat treatment characteristics, and heating the far-infrared radiation ceramics as a heating source of heat transfer or other fuel. Has the characteristics.

Therefore, the present inventors have developed a method for drying agricultural products with economical and high-quality products by simultaneously using far-infrared rays emitted from ceramics using heat sources generated from a hot air dryer.

In the present design, the radiation energy is radiated by the far-infrared rays radiated from the ceramic coated in the drying chamber of the dryer to solve the excessive use of fuel or electric power, which is pointed out as a problem in the conventional hot air dryer, and the quality of the dried agricultural products. As it progresses, it reduces fuel consumption by about 10% and drying time by about 8% compared to hot air dryer, and improves the taste by improving the quality of agricultural products and foods and the taste of far-infrared rays, and improves the storage by the sterilization effect. The purpose is to provide a hot air far-infrared dryer that can be.

In addition, the present invention provides a hot air far-infrared dryer designed to minimize far-infrared shade by emitting more than 0.93 far infrared rays in the wavelength range of 4 ~ 20㎛ in a state that the temperature in the drying chamber 40 ~ 90 ℃ in the ceramic coated on the inner surface of the drying chamber. Its purpose is to.

30: machine room 40: drying room

50: exhaust duct 60: burner

70: year 80: box stand

90: drying box 100: control box

In order to achieve the above object, according to the present invention, the entire inner part of the existing hot air dryer is coated with a ceramic paint in the form of sandpaper, and then calcined, so that far infrared rays of 4-20 μm are emissivity of not less than 0.93 by 40 to 90 ° C. Radiating to minimize the far-infrared shade drying chamber 40, exhaust duct 50 is installed on the top of the drying chamber for moisture control, the burner 60 is installed in the front of the machine room, and the flue 70 is installed on the upper machine room And, it is characterized in that the hot wind far infrared dryer configured to be used for drying at the same time the hot air generated by the plurality of drying boxes 90 to the box stand 80 installed on the drying chamber and the entire drying chamber.

Hereinafter, with reference to the accompanying drawings for the hot air far infrared dryer of the present invention will be described in detail.

1 and 2 show a perspective view of a hot air far infrared dryer that can be used in the present invention, the control box 100 is capable of precise temperature control in a certain temperature range according to the drying characteristics of the agricultural products to be dried. The temperature is measured by a temperature sensor (not shown) built into the drying chamber, and the measured temperature can be confirmed by a temperature indicator.

Temperature control must be accurate when the produce is dried, because the temperature control of 40 ~ 90 ℃ must be accurate in order to emit far infrared rays from the ceramic coated inside the drying chamber. In addition, there is a reason that the drying characteristics are different depending on the agricultural products. In the case of red pepper is a method of drying at a high temperature range rapidly increased initially and gradually lowering the temperature, while in the case of mushrooms at a lower temperature than red pepper This is because the temperature is gradually raised and dried for a long time at the elevated temperature to obtain a good quality dry mushroom.

Therefore, the hot air far-infrared dryer of the present invention has a function capable of precisely controlling the automatic temperature controlled by the control box 100 so as to adjust the temperature of agricultural products such as red pepper, mushrooms, radishes, ginseng, herbs and aquatic products such as anchovies. Can be dried through and has a feature that can simplify the operation.

When the desired temperature is set in the control box, the burner 60 is operated and fuel is supplied from the fuel tank 110 to repeat the operation of turning on and off according to the set temperature.

Hereinafter, the drying process by the hot air far infrared dryer of the present invention will be described.

FIG. 3 is a cross-sectional view illustrating a drying process of the hot air far-infrared dryer shown in FIG. 1, in which a machine room 30 including a heat exchanger 10 and a blower 20 is disposed on the left side, and the air sucked in through the suction port 31 is shown. Heat exchange is made in the heat exchanger 10 to generate hot air, and the hot air generated by the blower 20 to the lower part of the dryer is sent to the drying chamber through a perforated plate formed at the bottom of the drying chamber 40 to the drying chamber side. Supported by the box rack 80 formed at a predetermined height interval is to be made to circulate while passing through the drying box that can be conveniently stored inside the drying chamber.

Figure 4 shows another embodiment of the hot air far-infrared dryer shown in Figure 1, the hot air generated in the machine room 30 of the dryer and sent to the lower drying chamber 40 is loaded in the drying box through a plurality of perforations formed on the side of the drying chamber It is a circulatory system that rises while the produce is dried and flows back into the machine room.

3 and 4, the hot air introduced into the drying chamber 40 is controlled by the temperature setting of the control box so that the temperature inside the drying chamber is maintained at 40 to 90 ° C. in the ceramic coated and coated throughout the drying chamber. The agricultural and marine products loaded in the drying chamber are dried together with 4-20 μm far infrared rays having an emissivity of 0.93 or more.

The ceramics coated and coated in the drying chamber are micronized ceramic materials including ZrO 2 , Al 2 O 3 , SiO 2 , TiO 2 , Al 2 TiO 5 , 2MgO, 2Al 2 O 3 , 5SiO 2, etc., which have excellent heat resistance and adhesion. Next, the base material is made, and then baked in the drying chamber for the whole.

In addition, when the ceramic coating is applied to the entire drying chamber, the coated surface is treated like sandpaper surface, causing diffuse reflection to minimize the far-infrared shade to even the energy density and temperature distribution to improve the dry condition of the dried product to obtain high quality agricultural and marine products. It will be possible.
