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, an object of the present invention is to provide a grain and aquatic product drying apparatus that is high in drying efficiency and minimizes the deterioration of freshness.

The front door 41 allows the user to open or close the doors 35 and 52 of the hopper 34 and the drum 38 and to detach the unloader 46 from the front of the set housing 40. Is installed.

The drying process and operation of the grain and aquatic product drying apparatus according to the present invention are as follows. First, the user pours the object 100 into the hopper 34 as shown in FIG. 5 and rotates the hot air supply shaft 50 and the drum 38 by using the handle 48 and the raw material inlet of the drum 38. The raw material outlet of the hopper 34 is opposed. When the raw material inlet of the drum 38 and the raw material outlet of the hopper 34 face each other, the doors 35 and 52 are opened to open the raw material inlet and the raw material outlet. At this time, the object to be dried 100 is moved into the drum 38 in the hopper 34. When the object 100 is inserted into the drum 38, the user operates the keys of the control box 32 to drive the hot air blower 36 and the motor 42. Then, the hot air supply shaft 50 and the drum 38 rotate, and the hot air is supplied into the drum 38 through the perforations 50a of the hot air supply shaft 50. In this way, the dry object 100 in the drum 38 begins to dry due to the hot air supplied into the drum 38 and is completely dried after a predetermined time. While the dry object 100 is dried while the drum 38 rotates as described above, the stirring blades 39 rotate together with the drum 38 to mix the dry object 100 as shown in FIG. By blowing the dry object 100 in the internal air, the dry object 100 is allowed to dry evenly within a short time. On the other hand, in the case of the dried product 100 that is dried after being steamed, such as anchovy, the dried product 100 is dried at the same time as steaming by increasing the temperature of the hot air blower 36. Moisture and heat generated during drying of the object 100 are discharged to the outside of the drum 38 through the perforations 38a of the drum 38 and then discharged to the outside by the discharge fan 44. When the drying is completed, the user uses the handle 48 to face the raw material inlet of the drum 38 to the unloader 46 and then open the door 52 to unload the dried object 100 inside the drum. It is made to store in 46.

On the other hand, the unloader 46 located between the drum 38 and the discharge fan 44 may be taken out to the outside during drying to increase the discharge efficiency of the moisture and heat discharged from the drum 38.
