Description

[0001] DRYING APPARATUS WITH A PLURALITY OF EJECTOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying apparatus having a plurality of ejectors, and more particularly, to a drying apparatus having a plurality of ejectors for grasping a drying state of a drying subject and discharging dried objects after drying.

Drying apparatuses for removing moisture from objects are used in various forms throughout the industry. It is also used in the pelletization process of livestock, etc., and also in the manufacture of wood plywood. It is widely used for the drying of fruits, meat, fish and shellfish, etc., and a microwave oven is also included in such a drying device on a daily basis.

The drying apparatus removes moisture from the object by applying energy to the object. A drying device using microwaves is actively used because moisture can be removed without significantly deforming the object.

Microwave drying devices include conveyor drying devices and vacuum drying devices. The conveyor drying apparatus operates in such a manner that an object to be charged is dried while passing through the drying apparatus along the conveyor. Such a conveyor drying apparatus can continuously dry the object, but since the length of the object is long enough to dry the object, the volume occupying space becomes inevitably large. Also, as the length of the conveyor becomes longer, a large number of microwave generating devices are required, and the drying efficiency is relatively reduced because drying is performed in one conveyor line. On the other hand, the vacuum drying apparatus has a problem that the drying efficiency is considerably high but it is expensive.

1 is a schematic side view of a drying apparatus according to an embodiment of the present invention.
FIGS. 2A to 2D are schematic side views for explaining the state of the drying apparatus of FIG. 1 according to the drying process.

Hereinafter, a drying apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to FIG. 1, a drying apparatus 100 according to an exemplary embodiment of the present invention includes a heater 110, a transfer line 120, a vertical transfer unit 130, and a discharge unit 140.

The object to be dried, which is an object to be dried, may be introduced into the interior space of the drying apparatus 100 through the inlet 102 opened to one side along the conveyor 101 exposed to the outside. The material to be dried may be directly supplied by the user through a separate pretreatment process or may be delivered from a separate process line for performing the pretreatment process.

Meanwhile, a sensor (not shown) for detecting the laundry to be introduced may be disposed in the loading port 102 to determine whether the laundry is put in and input. Thus, the drying apparatus 100 can be automatically operated when the object to be dried is put in, and each of the structures can be controlled based on the amount of the object to be dried.

The inlet 102 is preferably disposed on the upper side in order to feed the object to be dried to the uppermost stage, but it is also possible that the object to be dried is conveyed to the uppermost stage through a separate conveying device.

On the upper side of the drying apparatus 100, a heater 110 is disposed, and electromagnetic waves are irradiated to the inner space. The heater 110 may be disposed outside the inner space and configured to radiate electromagnetic waves inward. The volume of the internal space, the weight of the object to be dried, and the like can be appropriately selected. Particularly, it is preferable that a plurality of heaters 110 are arranged widely so that electromagnetic waves can be uniformly irradiated, and electromagnetic waves may be irradiated from a single heater 110 in a plurality of directions.

The electromagnetic waves radiated from the upper side to the lower side are surrounded by the body (not shown) in the inner space of the drying apparatus 100, and can be directly or indirectly transmitted to the entire inner space. The body accommodates the heater (110) and the transfer line (120) therein and blocks leakage of electromagnetic waves irradiated from the heater (110) to the outside. Electromagnetic waves confined within the body by the body can reach the laundry on the lower transfer line 120. The irradiated electromagnetic waves can continuously apply heat to the plurality of transfer lines 120 instead of applying heat only to the single transfer line 120. As described above, the electromagnetic waves applied to the laundry on the single transfer line 120 are used for drying in the lower transfer line 120, thereby increasing the drying efficiency and saving energy.

The heater 110 may include a magnetron that generates microwaves. The microwave irradiated from the heater 110 is transferred to the drying object transferred on each of the plurality of the transfer lines 120, so that drying can proceed more efficiently.

The laundry which has passed through the inlet 102 and is introduced into the drying apparatus 100 is conveyed by the conveying line 120 disposed at the uppermost stage. The transfer line 120 disposed at the uppermost stage transfers the dry matter containing a relatively large amount of moisture as compared with the other transfer lines 120. Accordingly, the uppermost conveyance line 120 can smoothly convey the laundry by regulating the tensile force of the conveyor belt constituting the uppermost conveyance line 120 and applying a relatively large force as compared with the other conveyance lines 120.

The transfer line 120 transfers the material to be dried in the lateral direction under the heater 110. These transfer lines 120 include a plurality of transfer lines 120 arranged in the vertical direction on the lower side of the heater 110. As shown in the drawing, the plurality of transfer lines 120 are arranged so as to overlap with each other, so that the remaining transfer lines 120 except for the uppermost transfer line 120 are indirectly reflected by reflecting the electromagnetic waves on the body and the like.

The laundry is introduced into the uppermost transfer line 120 of the plurality of transfer lines 120. It is preferable that the laundry is transferred to the uppermost transfer line 120 closest to the heater 110 to receive more energy because the laundry is contained in a large amount of moisture in the laundry.

The conveying direction of each of the plurality of conveying lines 120 may be opposite to the conveying direction of the conveying line 120 adjacent to the upper and lower sides. That is, the plurality of transfer lines 120 can pass the lower side of the heater 110 several times while conveying the dried material in zigzag form. At this time, the objects to be dried are sequentially transferred from the upper transfer line 120 to the lower transfer line 120 by the upper and lower transfer devices 130, and a description thereof will be described later.

The laundry is gradually moved away from the heater 110 every time it passes under the heater 110 while being sequentially transferred by each of the plurality of transfer lines 120. [ The lower the amount of heat transferred through the electromagnetic wave is reduced. However, if the water content is low, the drying efficiency can be maintained even if a small amount of heat is applied, so that the dried material dried from the upper transfer line 120 can still be dried with considerable drying efficiency.

The conveyance line 120 disposed at the lowermost stage carries the laundry containing relatively less moisture than the other conveyance lines. Accordingly, it is possible to control the tensile force of the conveyor belt and to reduce the energy required to transfer the laundry by applying a relatively small force as compared with the other transfer lines 120.

Each of the plurality of transfer lines 120 may be constituted by a conveyor. Thereby, the drying object can be continuously dried, thereby reducing the drying time and increasing the drying efficiency. Meanwhile, the belt constituting the conveyor may be made of Teflon. This makes it possible to prevent a part of the drying object from sticking to the belt when drying the drying object.

Each of the plurality of conveyance lines 120 may be constituted by one conveyor having a wide width, but two or more conveyors may be arranged side-by-side, if necessary, such as providing a path for electromagnetic waves and a path for air .

On the other hand, the laundry can be transferred from the upper transfer line 120 to the lower transfer line 120 by the upper and lower transfer units 130. The upper and lower conveying lines 130 are disposed at both ends of the plurality of conveying lines 120 to convey the laundry conveyed by the upper conveying line 120 to the adjacent two conveying lines 120 to the lower conveying line 120 do. That is, the upper and lower conveying lines 120 and 120 are moved in the direction in which the upper conveying line 120 approaches the lower conveying line 120, Is disposed between the transfer lines (120). As a result, the upper and lower transporters 130 are arranged one after the other from left to right.

Referring to FIG. 2 (a), the upper and lower transporters 130 may be inclined such that the upper surface thereof faces the inner transfer line 120. As shown in FIG. 2 (b), the material to be dropped from the upper conveying line 120 to the upper conveying line 130 can be conveyed downwardly to the lower conveying line 120 by being inclined upward. Or may be transferred to the lower transfer line 120 through a separate conveyor as shown in FIG. 2 (c). Particularly, in the case of the wooden plywood, the object to be dried may not be smoothly transported when it is simply dropped from the upper transfer line 120 to the lower transfer line 120 and then transferred smoothly. In this case, ), It is possible to prevent the hanging of the object to be dried and to carry the upper and lower transfer more easily. In addition, the occurrence of a failure can be reduced by carrying out vertical transfer with a simple structure.

The dried object to be dried is discharged to the outside through one of the plurality of discharge units 140 disposed on the side of the transfer line 120. The discharger 140 may be connected to the upper and lower transporters 130 disposed on one side with respect to the plurality of transfer lines 120. When the object to be dried which is approaching to the Shanghai transfer device 130 is dried to a predetermined water content or less, the discharge device 140 can take the material to be dried from the transfer device 130.

2 (a) to 2 (c), the discharger 140 is spaced apart from the upper and lower sides of the upper and lower distributors 130 in the non-operation state, The upper and lower sides of the upper and lower sides of the upper and lower sides of the upper and lower sides of the upper and lower sides of the upper and lower sides, respectively. First, when one end of the object to be dried comes into contact with the discharge unit 140, the object gradually rises and falls to the discharge unit 140 side. The discharge device 140 draws the object to be dried up and discharges the object to the discharge port 103 side before the object to be dried falls down the inclined upper surface of the upper and lower transporters 130 and again enters the transfer line 120.

Meanwhile, the structure of the discharger is not limited to that shown in the drawings, and various known structures capable of discharging the dried material from the transfer line 120 to the outside can be freely adopted.

Above the plurality of transfer lines 120, a pressure belt 150 may be provided to apply pressure to the material to be transferred on the transfer line 120. The pressurizing belt 150 presses the laundry downward so that the laundry is transported in an ordered state when the laundry is introduced into the transfer line 120 from the inlet 102 or the upper and lower distributors 130. As a result, it is possible to prevent the other objects from being hindered when the laundry is introduced into each of the transfer lines (120).

Meanwhile, the drying apparatus 100 according to an embodiment of the present invention may further include a blower (not shown) for supplying outside air to the inside. The blower is disposed below the plurality of transfer lines 120 and blows air upward to push upward the water vapor from the laundry. An exhaust port may be provided on the upper side of the plurality of transfer lines 120 to discharge the water vapor to the outside. It is possible to remove the water vapor in the inner space of the drying apparatus 100 to the outside, thereby continuously drying the laundry, thereby improving the drying efficiency.

The dried object to be dried is discharged to the outside of the drying apparatus 100 along a conveyor 104 exposed to the outside through an outlet 103 opened to the opposite side of the inlet 102. The material to be dried may be directly discharged by the user through a separate post-treatment process, or may be delivered to a separate process line for performing a post-treatment process.

On the other hand, each of the inlet 102 and the outlet 103 may be provided with an electromagnetic wave shielding filter (not shown) for preventing leakage of electromagnetic waves to the outside. Since the interior space of the drying apparatus 100 is difficult to be completely sealed due to the input and discharge of the object to be dried, the electromagnetic wave is restrained by the electromagnetic wave shielding filter in the inner space, thereby preventing the user from being exposed to electromagnetic waves.

The drying apparatus 100 according to one embodiment of the present invention may further include a control module (not shown). The control module controls the input amount of the laundry, the irradiation amount of the electromagnetic wave from the heater 110, or the feeding speed of the feeding line 120 based on the temperature and humidity of the space inside the drying apparatus 100.

In addition, the drying apparatus 100 according to one embodiment of the present invention may further include an input / output module (not shown). The input / output module may include a touch screen panel capable of simultaneously performing input and output operations.

The input / output module can display the temperature and humidity of the interior space of the drying apparatus 100, the input amount of the object to be dried, the electromagnetic wave irradiation amount by the heater 110, and the transfer speed of the transfer line 120 as images. The input amount of the object to be dried, the irradiation amount of the electromagnetic wave by the heater 110, and the control information on the conveying speed of the conveying line 120 can be inputted through the input / output module.

Hereinafter, a process of drying the object to be dried by the drying apparatus 100 according to an embodiment of the present invention including the above-described components will be described.

When the type and amount of the object to be dried are determined, the transfer speed of the transfer line 120 is determined in consideration of the time required for drying the object to be dried and the amount of heat supplied from the heater 110.

Control information such as an output value of the heater 110 and a conveying speed of the conveying line 120 is inputted through the input / output module before the drying apparatus 100 is operated. Such control information can be changed automatically or manually by observing the drying process in real time.

When the preparation is completed, the laundry is put into the inlet 102 and the drying apparatus 100 is operated. The charged dried material is heated by the microwave irradiated from the heater 110. The dried material absorbs the most heat on the conveying line 120 disposed at the uppermost stage, and drying proceeds with the highest drying efficiency.

The dried material having passed through the uppermost transfer line 120 is transferred to the lower transfer line 120 through the upper and lower transfer units 130. The articles to be dried dropped from the side of the upper conveying line 120 descend along the inclined surface of the upper conveying machine 130 and are conveyed to the lower conveying line 120.

While the drying is progressing in the lower transfer line 120, the drying object is continuously put into the uppermost transfer line 120 and dried. On the other hand, although the object to be dried in the second transfer line 120 receives microwaves whose intensity is weaker than that in the uppermost transfer line 120, since the object is already dried to some extent while passing through the uppermost transfer line 120, the drying efficiency is drastically low It does not support.

In the same manner, the drying of the laundry is carried out on the third transfer line 123. As the temperature goes down, the intensity of the microwave transmitted decreases, but the drying efficiency can be maintained at an appropriate level considering the residual water amount.

There is a case where the drying object is dried while being conveyed and having a water content equal to or lower than a preset value. Since the moisture content at the time of charging is different for each material to be dried, it is possible to reach the target dry state before reaching the lowermost transfer line 120.

At this time, the object to be dried is discharged to the outside through the discharger 140 reaching the predetermined moisture content immediately after drying. First, the moisture content is measured by a sensor (not shown) capable of measuring the amount of water contained in the object to be dried when the object reaches the side end. At this time, when a value exceeding a preset moisture content is measured, the laundry is transferred to the lower conveying line 120 by the upper and lower transporters 130. However, when the measured value is less than a predetermined moisture content, the discharger 140 is lifted up and withdraws the object to be dropped from the vertical transfer device 130 to the discharge port 103 as shown in FIG.

By drying the dried object in advance, it is possible to prevent the dry object from being excessively dried to be deformed or deteriorated, and it is possible to prevent unnecessary transfer of the heat to the dried object to be dried, Can be increased.

The dried material that has not been discharged by the discharger 140 is continuously dried on the transfer line 120. As described above, the drying of the dried object after the water content is measured again is discharged to the outside by the discharger 140. The remaining dry matter is conveyed to the lowermost conveyance line (120), dried, and discharged to the outside through the lowermost discharge port.

In summary, through the drying apparatus 100 according to an embodiment of the present invention, the object to be dried is conveyed to pass the lower side of the heater 110 for irradiating the microwave more than twice, And when the drying is completed in the middle, it is immediately discharged to the outside by the discharger 140, and the drying of the remaining dry matter is further progressed.

In this manner, instead of drying the objects to be dried by disposing the heaters individually on the transfer lines arranged long in a single line, the heaters 122 are arranged on one side and the transfer lines 120 are arranged so as to overlap vertically below the heaters 122 So that the object to be dried can absorb the microwave irradiated from the heater 110 as much as possible. Accordingly, the amount of power consumed when drying the object to be dried can be minimized, and a relatively small number of the heaters 110 can be used.

Although the embodiments of the present invention have been described in detail with reference to the accompanying drawings, it is to be understood that the present invention is not limited to those embodiments and various changes and modifications may be made without departing from the scope of the present invention. . Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
