The present invention relates to a method for drying and an agricultural and livestock product dryer using the apparatus.

The drying method of agricultural and marine products uses a variety of drying methods and various devices according to the drying method. The traditional method is to use the drying method by solar heat or the drying method by natural wind, which has a problem that it takes time and depends on the weather.

In general, the heat drying method is time-consuming and nutrients are considerably destroyed by heat, and a large amount of heat is required, which leads to high drying costs and labor costs.

With the development of civilization, the technology of using hot air by using a machine or removing moisture from dry matter has been developed day by day, ranging from solar drying to bulk drying (hot air drying) to freeze vacuum drying. Recently, most of the agricultural and aquatic products are dried by the bulk drying method, but the cost of drying is high due to the rising oil price, and the quality is much lower than that of freeze vacuum, and the freeze vacuum drying is the most perfect drying method.
