Description

Drying Equipment {AGRICULTURAL AND MARINE PRODUCT DRYER}

The present invention relates to a drying apparatus, and more particularly, to a drying apparatus that not only increases energy efficiency by using a combination of far-infrared irradiation and heater heating, but also does not cause nutrient destruction.

The conventional method of drying existing crops is a method of naturally drying by exposure to the sun for a long time. This conventional method has the advantage that the nutrients are preserved intact, but it takes too much time, and the farmer has had to hang and walk on his own for such a long time. In addition, these traditional methods are heavily influenced by the weather, so they often see rain or rain during the drying period.

In order to solve the problems of the conventional method, a drying apparatus adopting a heater heat-heating method for applying heat to dry using a heater has been widely used. However, the heater heating method has a problem in that excessive costs are generally required because electricity or oil is used as an energy source. Furthermore, the application of only the heater heating method for the entire drying time has the disadvantage of easily breaking down nutrients.

Therefore, recently, a device for irradiating and drying far-infrared rays on crops or marine products has been proposed. Korean Patent Laid-Open No. 10-2010-0013064 discloses a drying apparatus employing a far infrared lamp as a heating apparatus. The apparatus is provided with a moving device capable of moving a plurality of trays up and down in a drying chamber divided into a front chamber and a rear chamber and also moving the front chamber rear chamber. In addition, there is provided a lamp heating device made of a far-infrared lamp installed on the ceiling and a heating device made of an electrical panel installed on the side wall and the door wall. It also has a plurality of fin tubes for the circulation of heat.

The prior art disclosed patent has the advantage that the environmentally friendly drying operation without destroying nutrients can be performed in that the far-infrared lamp is employed as one of the heating devices. However, this apparatus has a problem that it is difficult to be practically distributed to farms by including too complicated mechanical components. First of all, the device itself is too expensive and the operating costs are excessive. In addition to the heaters, a moving device for moving the tray is installed so that the price of the device increases, and a large energy can be consumed to operate such a moving device. Moreover, since the components of the moving device are operated while being exposed, unnecessary contaminants may be generated by dust or lubricating oil.

Therefore, such a device may not be practically a farmhouse supply type, and may be considered to be suitable for carrying out a bulk drying operation. Indeed, it costs too much for the farm income earned by drying agricultural products.

In addition, this conventional apparatus has a problem that the user can operate correctly only in the state of knowing the unique drying conditions for each drying object. For example, a variety of crops, such as medicinal and special applications are produced in farms, and there is an optimum drying condition for each of these various crops, but in the above-described conventional apparatus, there is a problem that the user must manually set the temperature manually.

The present invention is to solve the problems of the conventional apparatus, and provides a drying apparatus that can achieve the optimum drying results for agricultural and marine products at a reasonable cost by using a combination of a far-infrared lamp and a heater heating unit as a heating unit.

The present invention also provides a drying apparatus that can automatically apply the optimum drying conditions for the individual drying objects according to the user's choice.

The present invention provides a drying apparatus, comprising: a drying chamber provided by a body and a door; A holder for supporting a plurality of channels in the drying chamber so as to be stacked with each other therebetween; A far-infrared irradiator including a plurality of far-infrared lamps installed in the drying chamber; A heater installed on the lower side of the drying chamber; A temperature sensor installed to sense a temperature inside the drying chamber; And a controller configured to store drying conditions for a plurality of types of objects to be dried, receive a detection value of the temperature sensor, and control the far-infrared irradiator and the heater to satisfy the conditions for drying the selected type of objects to be dried.
