Description

Drying device using near infrared rays {chassis frame for electric cars}

The present invention relates to a drying apparatus, and more particularly, to a drying apparatus using near infrared rays capable of drying agricultural products, marine products, etc. using near infrared rays.

In general, drying is performed by heating the air in the drying room or directly heating the product to be dried.

In the process of drying the dried product by this dryer, 50 to 80% of moisture is contained in the air flowing inside the dryer. There is a problem in that the circulation of air containing moisture in the air reduces drying efficiency and increases energy consumption for drying. In addition, in the case of products dried by a dryer, especially agricultural products, there is a problem in that turbidity increases or color changes due to surface oxidation caused by heat and air contact.

On the other hand, the dryer using near-infrared rays closest to the radiant heat of the sun uses short-wavelength rays in which heat is transferred in wavelength only to the product to be dried, thereby eliminating the risk of fire, harmless to the human body, and especially reducing the turbidity of the product to be dried. change can be reduced.

Republic of Korea, Registered Patent Publication No. 1379849 has posted an agricultural product dryer. The posted agricultural product dryer is installed via a lamp installation frame on the upper side of the transfer roller conveyor, and includes a near-infrared ray lamp unit to evaporate the moisture of the agricultural products transported through the transfer roller conveyor; A circulation fan that circulates air in the inner body in a direction opposite to the transport direction of agricultural products; It is composed of, etc.

Since this agricultural product dryer has a structure using a transfer roller conveyor having a predetermined length, the installation location is restricted, and the drying efficiency cannot be improved because the humidity of the internal air generated during the drying process is high.

And Korean Patent Publication No. 2019-0085651 discloses a rotary dryer using near-infrared rays. This dryer has a body with a near-infrared lamp; Drying means for accommodating trays in multiple layers on a drying frame and flowing air through a blower; A driving means for inducing rotation by connecting a geared motor to the drying frame.

Republic of Korea Patent Publication No. 2015-0040092 discloses a near-infrared cold and warm air pressure-reduced dryer. The posted dryer includes an upper partition wall that is located above the drying chamber in which the object to be dried is dried and forms an upper air circulation chamber for partitioning the space; a blower fan installed on the rear side of the upper air circulation chamber of the upper bulkhead to blow indoor air through the upper air circulation chamber to the front air circulation chamber at the front of the drying chamber, the drying chamber, and the rear air circulation chamber at the rear of the drying chamber; an evaporator and a condenser installed between the rear air circulation chamber and the blowing fan; and a near-infrared ray generator installed between the trays on which the drying object is dried to radiate near-infrared rays to the object to be dried.

Since the front air circulation chamber and the rear air circulation chamber are provided, the design freedom of the drying chamber cannot be increased. In particular, since the evaporator and condenser are installed between the rear air circulation chamber and the blowing fan, the structure is relatively complicated. In addition, since the chips stacked on the rotating tray have a structure in which they are stacked in a horizontal state, there is a problem in that the near-infrared rays generated from the near-infrared ray generator cannot be uniformly irradiated to the object to be dried.
