Description

Drying Apparatus For Agricultural-Ocean Products

The present invention relates to an apparatus for drying grains or aquatic products, and more particularly, to a drying apparatus having a high drying efficiency and minimizing a decrease in freshness.

In order to preserve grain and aquatic products for a long time, a drying method is used. Drying grains and seafood is small even if stored for a long time. Such drying methods are roughly classified into natural drying, also referred to as sun drying, and artificial heating drying, which is artificially dried using various heat sources. The former natural drying is a method of drying grains and seafood using solar heat and wind as a traditional drying method. This method has the advantage of not having fuel costs, but it takes a long time to dry and has a big disadvantage of quality change according to climate change. Artificial heating drying requires a lot of expenses on equipment and heat sources, but it has the advantage of short drying time. The artificial heating drying method is natural ventilation drying method, hot air drying method, and film drying method. Among these, a hot air drying type dryer is mainly used as a cabinet type dryer as shown in FIG. 1, and a film drying type dryer includes a drum type dryer as shown in FIG. 2.

Referring to FIG. 1, a cabinet type dryer includes a shelf 4 in which dry items are stored, a heater 10 for generating heat, a fan 14 for circulating heat generated from the heater 10, and a shelf. (4), the heater 10 and the fan 14 are provided therein, and are provided with the set housing 2 in which the inlet port 6a and the exhaust port 6b are formed. In the shelf 4, the washed dry items are stored in a predetermined amount for each floor. The fan 14 is installed between the suction port 6a and the heater 10 to supply cold air flowing from the suction port 6a toward the heater 10. The ventilation controller 12 is installed between the fan 14 and the heater 10. Ventilation regulator 12 serves to adjust the amount of air flowing from the fan 14 toward the heater 10. The heater 10 generates heat in accordance with the current signal supplied to it. The heat generated from the heater 10 dries the dry items stored in the shelf 4. Heat and moisture passing through the shelf 4 are discharged to the outside through the exhaust port 6b.

Cabinet-type dryers such as Figure 1 has a problem that the moisture generated during drying is introduced into the lower layer or another layer of the upper layer. Accordingly, the cabinet type dryer has a disadvantage in that drying of the dried material takes a long time of about 2 to 4 days because of poor drying efficiency. In addition, in the cabinet-type dryer, the dry items are placed on the shelf 4 so that heat is not evenly supplied to every corner.

Referring to FIG. 2, the drum type dryer includes a raw material supply pipe 24, heating drums 22a and 22b through which a dry matter is supplied from the raw material supply pipe 24, and a raw material supply pipe 24 and heating drums. 22a and 22b are provided with the set housing 30 installed inside. The heating drums 22a and 22b are heated from a heat source (not shown) installed below and rotated in opposite directions. On the surfaces of the heating drums 22a and 22b, a dry matter 26 in a liquid state, particularly a paste state having a low viscosity, supplied from the raw material supply pipe 24 is adsorbed. The dry object 26 having a film formed on the surfaces of the heating drums 22a and 22b is dried by the heat of the heating drums 22a and 22b. The dry object 26 dried by the heating drums 22a and 22b is separated from the heating drums 22a and 22b by the blade 28.

The drum type dryer as shown in FIG. 2 has the advantage of being suitable for drying the liquid raw material by forming a film of the dry matter on the heating drums 22a and 22b. However, the raw material dried in a state where the basic shape is maintained, for example, pepper is difficult to dry, the drum-type dryer has a problem that there is a limit to the raw material selected as the dried material. In addition, since the drying object is dried only depending on the heat of the heating drums 22a and 22b, the power consumption of the heat source for heating the heating drums 22a and 22b outside the heating drums 22a and 22b is large and the drying efficiency is high. There is a low problem. In addition, the drum type dryer dries the dried product in the form of a film at high heat, thereby deteriorating the freshness of the dried product, such as altering the taste and aroma of the dried product.

Accordingly, it is an object of the present invention to provide a grain and aquatic product drying apparatus which is high in drying efficiency and minimizes a decrease in freshness.
