Description

{AGRICULTURAL PRODUCTS DRYER} WITH DRY Waste Heat Recycling Function [

The present invention relates to a dryer for drying agricultural products, aquatic products and forest products (hereinafter referred to as agricultural, water, and forest products), and more particularly, The present invention relates to a rotary type agricultural and marine product drier having a function of uniformly drying both upper and lower layers at the same time, recovering heat from the discharged hot air stream, heating external inflow air, and recycling dry heat as dry heat.

Generally, in order to commercialize agriculture, water and forest products, it is necessary to dry after harvesting. The representative crop is pepper.

Conventionally, a dryer for drying agricultural, horticultural and forest products using hot air has been developed. Conventionally, a dryer for drying agricultural, horticultural, and forestry products houses agriculture, water, and forest products in a shelf disposed inside a case, To provide hot air to dry agricultural, water and forest products.

However, most dryers that simply provide hot air to the inside of the case to dry the crops may not be able to uniformly provide hot air to the drying troughs arranged in multi-stages, or interfere with the hot air stream after drying between the drying troughs, Uneven drying occurs.

In recent years, some drying element parts have been improved to somewhat improve the problem of nonuniform drying, but the problem of nonuniform drying has not been solved fundamentally.

The dryer, which is operated without the solution of the above problems, needs to supply more energy to the case than the energy required to dry the agricultural, water and forest products, which causes the energy to be consumed more than necessary, And the drying quality of agricultural, water and forest products is low.

In order to increase the heat efficiency of the dryer, there is a product for drying the agricultural products, aquatic products and forest products with the heat recovery device. However, since the additional space must be secured separately from the dryer, the volume is increased and the efficiency is also low.

Recently, a circulating hot air dryer (registered utility model: 20-0403913) has been proposed as a structure for rotating the entire drying tray (drying table) in order to solve the problem of interlayer uneven drying of the multi- However, the problem of nonuniform drying between dry bed layers is not solved.

The reason for this is that the waste air air outlet for discharging the waste heat air from which the laundry is dried is disposed at a lower portion of the dryer (not shown) The drying hot air can not flow uniformly into the respective trays and the tilting phenomenon occurs toward the waste heat air outlet port, thus failing to solve the problem of drying the interlayer unevenness of the drying towers. In addition, there is a problem in that the heat recovery efficiency can not be improved because a heat recovery device for recovering heat from the waste heat air after drying is not provided.
