Description

MULTIPURPOSE DRYING DEVICE OF AGRICULTURAL PRODUCTS}

The present invention relates to a multi-purpose drying device for farm products, and more particularly, to a multi-purpose drying device for producing a variety of agricultural products produced in a farm by using a hot hot air for multi-purpose.

As is well known, conventionally, agricultural products produced in farms have been dried using solar heat, but machine drying using a drying apparatus has been popularized due to the increase in production and the reduction of labor due to the development of agricultural technology.

At present, a circulating drying device developed for drying rice, or an airtight drying device for drying shiitake or red pepper, has been developed and used among conventional agricultural products.

However, conventional circulation drying apparatus or hermetic drying apparatus has a disadvantage in that it is not possible to effectively dry various kinds of agricultural products such as steamed rice, siraegi, fern, radish, bellflower, jujube, beans and the like.

In the case of steamed rice, it is soft like rice, so it is not possible to dry it with the conventional circulation drying device manufactured to dry rice, and there is a risk of burn because the temperature is over 300 ° when steamed rice is removed from the steamer. Dried shiitake or chili peppers in a closed dryer made to dry it becomes difficult to dry.

In addition, agricultural products such as siraegi, fern, radish, bellflower, jujube and soybeans also have different drying characteristics. Becomes difficult.

Therefore, agricultural products such as rapeseed, fern, radish, bellflower, jujube and soybeans are dependent on manual sun drying. When the agricultural products are sun-dried as described above, ultraviolet rays penetrate and become gray or black, thereby degrading the value of the product or impregnated by wind, and thus improper hygiene.
