The present invention relates to a dryer, and more particularly, to a stationary far-infrared dryer which can not only uniformly dry in a multi-stage drying box but also double dry using a far-infrared radiation plate to obtain high-quality agricultural products.

Generally, it distinguishes the multi-purpose dryer that can dry a wide range from agricultural products other than grains such as pepper, mushroom, tobacco, ginseng, herbal medicine to aquatic products such as anchovy, seaweed, and seaweed, from grain (rice, barley, wheat, etc.) dryers. It is called agricultural product dryer. In this agricultural product dryer, the dry product is put into a multi-stage drying box (porous plate) in a drying chamber and forced hot air indirectly heated into the drying chamber by using a burner and a heat exchanger, whereby hot air passes through the dry product. After the recirculation or dehumidification to go out of the drying room to dry by the artificial drying method has a merit that can produce a high value of dry agricultural products in a short time compared to the drying using the sun drying.

Such a agricultural product dryer has a stationary type in which a drying box is placed on a shelf and a circulation type in which the drying box is circulated. Here, briefly, the stationary dryer is the most widely used agricultural product dryer, which puts the dried goods in a drying box and puts them on a shelf to dry them until the end of drying. have. However, there is a problem that non-uniform drying occurs between the upper and lower layers because the under wind type feeds hot air under the drying chamber. The newly developed method to solve this problem is side-winding.

1 is a view schematically showing such a side wind dryer. Referring to FIG. 1, the side wind dryer 10 is divided into a heat exchange chamber 30 and a drying chamber 50 in a housing 20 having a rectangular box shape. The heat exchange chamber 30 is provided with a burner 32 and a blower 34, and when hot hot air is sprayed to the lower side of the drying chamber 50, the hot air is returned to the upper side to form a circulation. The drying chamber 50 is provided with a drying rack 60 in which a drying box 62 having a hole in the bottom surface is installed in multiple stages. The hot air suction path 66 is formed on the side of the drying rack 60 to suck the hot air introduced into the lower side of the drying rack 60. At this time, the hot air inlet hole (not shown) is formed on the side of the drying rack 60 so that the hot air is moved from the hot air suction path 66 to the lower side of the drying box 62.

The operation state of the side wind dryer 10 formed as described above will be briefly described. When hot air heated by the burner 32 of the heat exchange chamber 30 is sprayed to the lower side of the drying chamber 50 by the blower 34, the hot air Is introduced through the lower portion of the hot air suction path (66). As such, the hot air introduced into the hot air suction path 66 is again introduced into the respective drying boxes 62 through the hot air injection holes. The hot air introduced into the drying rack 60 dries the dry items placed on the upper part of the drying box 62 while passing through the drying box 62. The hot air which dried the to-be-constructed object is convection to the upper side of the drying table 60, and it circulates again to the heat exchange chamber 30.

However, the dryer thus formed has a problem in that the dry items in the upper drying box are dried more than the dry items in the upper drying box, although not as much as the downwind dryer, since the hot air passing through each drying box is moved upward by convection. .

 The present invention has been made to solve the above-mentioned conventional problems, by installing a far-infrared radiation plate between the drying box in the drying rack to block the hot air to move to the upper side and suck the hot air dried on the dry object in the hot air suction path By providing a suction duct, it is possible to provide uniform drying in each drying box, as well as to provide a fixed far-infrared dryer which can obtain high quality agricultural products by double drying using a far-infrared radiation plate.
