The present invention relates to a drying apparatus, and more particularly, to a drying apparatus that allows to dry quickly and uniformly using hot air and microwaves while moving a drying object at an appropriate speed.

As a conventional drying apparatus using microwaves, there is a pre-registered patent No. 414935 of the present applicant, which disperses the microwaves evenly on the inner wall surface of the drying chamber in which the entry and exit ports are opened or closed manually or automatically by the door. When the member is placed and the object to be dried is brought into the drying chamber, the loading and unloading ports are closed, and then the microwaves generated by operating the magnetron installed at the outside of the drying chamber are brought into the interior of the drying chamber through the waveguide, and the whole interior of the drying chamber is opened by the dispersion member. By evenly dispersing to evenly to the dry object (照射) to be uniformly irradiated (照射) by the friction heat generated by the water molecules of the water absorbed by the drying object is evaporated by the moisture to evaporate to dry.

By the way, the above-mentioned registered patent has a door before the magnetron is operated in order to prevent the microwaves from leaking to the outside through the loading and unloading port when the drying object is carried in the drying chamber and then the magnetron is operated. Since it is configured to close first, the drying step is interrupted in the process of importing and exporting the drying object, and the drying step is intermittently performed. As the drying step is performed in a single drying room, all the water absorbed by the drying object is evaporated. Since it takes a long time to remove, there were problems such as a decrease in drying efficiency and a decrease in productivity per unit time.

In addition, since each door must be opened and closed every time the object to be dried is brought into the drying chamber or taken out through the outlet after completion of drying, additional equipment for opening and closing the door is required. In addition to the overall complexity, there was also a problem such as an increase in manufacturing cost due to the increase in the number of parts and assembly due to additional equipment.

The present invention has been invented in view of the above-described problems of the applicant's prior registered patents, and an object thereof is to provide a drying apparatus in which the drying efficiency is greatly improved per unit time, thereby greatly increasing productivity and reducing manufacturing costs.

Another object of the present invention is to provide a drying apparatus that can be used to dry various kinds of objects.

The above objects of the present invention, the drying step is carried out in the first to third steps by using hot air and microwave in the process of moving the drying object at an appropriate speed and at the same time do not open and close the entrance and exit to the door It is achieved by providing a drying apparatus configured to prevent the microwaves from leaking to the outside even if the drying apparatus is installed between the inlet and the outlet of the base in turn, and the first drying chamber and the hot air, which firstly dry the object to be dried using hot air. And is installed between the front and rear ends of the base to be rotated through the interior of the second drying chamber and the third drying chamber to dry the third using hot air and the third drying chamber using the hot air. Hot air to the first and third drying chambers and the conveyer which moves the object from the loading part through the 1-3 drying chamber to the carrying out part When installed and operated on both sides of the hot air fan for supplying and the outer surface of the both side walls of the second drying chamber, it comprises a magnetron for supplying microwaves to the inside, and when used, on the carry-in side of the conveyer is rotated at an appropriate speed When it is placed up, it moves and passes through the 1-3 drying chamber in sequence. In this process, the first drying step is performed to evaporate the moisture on the outer surface with hot air in the first drying chamber, and inside the second drying chamber by hot air and microwaves. The second drying step is performed to evaporate all the water absorbed in the third drying chamber, and the third drying room evaporates the hot air if there is water remaining on the outer surface of the water from the inside during the second drying step. Drying efficiency per unit time is greatly increased because the step is performed and completely dried. It has a characteristic such that as soon the drying time is greatly reduced at the same time.

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

It is a wavelength diagram showing an enlarged wavelength of the microwaves reflected by the phase is generated differently, Figure 7b is a state diagram in which each of the microwaves having the same phase is irradiated to each site of one sterilization object.

The drying apparatus according to the embodiment of the present invention includes the first to third drying chambers 20, 30 and 40, which are sequentially installed between the carrying-in part 11 and the carrying-out part 12 of the base 10, and the agent. Distribution ports 21, 31 and 31 formed in the transverse direction at each lower portion of the partition walls 30a and 30b partitioning between the front and rear walls 20a and 40a of the first and third drying chambers and the 1-3 drying chamber. A conveyor 50 installed between the front end and the rear end of the base to pivot through the '41' to move the drying object from the loading part through the 1-3 drying chamber to the loading part; 1-3 Hot air blowers 60 for supplying hot air into the respective drying chambers through supply ports 22, 32 and 42 formed at the bottom of the drying chamber, respectively, and do not face each other outside the walls on both sides of the second drying chamber. The magnetron 70, which oscillates microwaves incident to the interior of the second drying chamber when installed and operated at the position, is installed at each of the distribution ports and leaks of the microwaves through the distribution ports. It comprises a shield member 80 to block the.

The first drying chamber 20 is installed in a rectangular shape in which the upper part is opened immediately behind the carrying-in part 11, and is buried on the outer surface of the drying object carried in through the distribution port 21 of the partition wall 20a and passes through the inside. The primary drying step is performed so that the moisture is evaporated by the action of the hot air supplied through the supply port 22 formed in the bottom.

Then, the open upper part of the drying chamber 20 is opened and closed by the cover 23, and the moisture and residual heat evaporated from the drying object by the hot air during operation, the exhaust pipe 13 to which the exhaust port 231 of the cover is connected. Through the outside.

The second drying chamber 30 is installed in a rectangular shape in which the upper part of the second drying chamber 30 is opened immediately after the barrier rib 30a at the rear of the first drying chamber 20 and passes through the distribution port 31 to pass through the interior. A second drying step is performed to dry the object by microwaves that are oscillated by the operation of the magnetron 70 installed on the outside of the hot air supplied through the supply port 32 formed on the bottom and both side walls 33.

Then, the open upper part of the drying chamber 30 is opened and closed by the cover 35, and the moisture and residual heat evaporated from the object to be dried by performing the secondary drying step by hot air and microwaves during operation are exhaust ports 351 of the cover. ) Is discharged to the outside through the exhaust pipe 13 is connected to at the same time to prevent the leakage of microwaves.

Inside the both side walls 33, a dispersing member 34 is installed when the magnetron 70 installed on the outside is actuated and diffuses the microwaves incident to the inside of the second drying chamber 30 to evenly distribute the microwaves. do.

The dispersion member 34 is made of a material that reflects microwaves, such as aluminum, and divides the full width F into six equal parts in equal widths so as to ideally disperse the microwaves in consideration of the wavelength of the microwaves. Are the same, but have six reflecting portions 34a having different lengths (l).

Each reflector 34a comprises a horizontal plane 341 and a vertical plane 342 connecting the horizontal planes to each other. When microwaves are incident, the reflecting parts 34a collide with the surfaces of the reflecting parts of the dispersing member 34 facing each other to be reflected and distributed to each other. Since the process of hitting each reflecting part of the member and reflecting and returning again is repeated, it is evenly distributed throughout the inside of the second drying chamber 30.

In this way, the traveling waves and the reflected waves of the microwaves are generated microwaves (ae) having different phases according to the difference in the length of the reflector 34a, as shown in Figure 7a, these microwaves are irradiated to one drying object (1) Each part is different as shown in FIG. 7B, but since the sum of the irradiated parts becomes the whole part, the microwave is uniformly irradiated onto the whole part (a + b + c + d + e) of the object to be dried.

On the other hand, when the dispersing member 34 is installed inside the two side walls 33, the total length of the wall surface is longer than the full width F of the dispersing member, so that the plurality of dispersing members 34 are vertically installed in parallel with the total length of the two side walls. Just do it.

However, if necessary, such as mass-producing a drying apparatus of the same standard, the dispersion member 34 made of a single body such that the six reflecting portions 34a are set in proportion to the total length of both side walls 33 so that they can be repeated repeatedly. In this case, in consideration of replacement due to partial damage or easy molding of the reflecting part, which is caused by long-term use, it is possible to use a structure having only one set of six reflecting parts. It is preferable.

By dispersing the microwave evenly by installing the dispersing member 34 as described above, water is deposited on the outer surface because it is evenly irradiated to all parts of the drying object that is carried through the distribution port 31 and passes through the interior of the drying chamber 30. Of course, the water molecules of the water absorbed therein are evaporated due to the increase in frictional heat generated by the vibration of the microwaves, and all of them escape uniformly at the same time, so that drying occurs quickly and completely.

On the other hand, the dispersion member 34 may be installed only on both walls 33 when the internal space of the drying chamber 30 is not large, but in the possible positions of the top and the bottom when the internal space is large. Of course, the installation number and position of the magnetron 70 can also be adjusted as needed.

In addition, it is preferable to install a diaphragm 36 made of a material through which microwaves are transmitted, such as a heat-resistant resin, on the inner side of both walls 33 so that the dispersion member 34 is not exposed to the inside. In addition to the damage that may be caused by hitting the reflecting portions 34a of the dispersing member during the movement process, foreign substances may be caught between the reflecting portions, and the like, such that the shortening of lifespan is prevented and Washing etc. becomes easy.

In addition, in the drying chamber 30, since the object to be dried is a substantial drying step performed by hot air and microwaves, the total length is longer than that of the first and third drying chambers 20 and 40, and the amount of evaporation of moisture is rapidly discharged. In order to achieve this, it is preferable to provide a plurality of exhaust ports 351.

The third drying chamber 40 is installed in a rectangular shape in which an upper portion thereof is opened immediately after the barrier rib 30b at the rear of the second drying chamber 30, and the object to be dried is carried in through the distribution port 31 ′. In the process of passing through the second drying chamber, if water absorbed therein is completely escaped by the action of hot air and microwaves and remains on some outer surface when evaporated, it is supplied through the supply port 42 formed at the bottom. A third drying step is performed in which hot air is evaporated.

Therefore, in the case of a drying object that is completely dried only by the first and second drying steps because the content of moisture is not high, the third drying step may not be performed. Accordingly, the third drying chamber 40 may be selectively operated.

In addition, the open upper portion of the drying chamber 40 is opened and closed by the cover 43, and the moisture and residual heat evaporated from the drying object by the hot air during operation is through the exhaust pipe 13 to which the exhaust port 431 of the cover is connected. Allow to be discharged to the outside.

On the other hand, the supply port 22, 32, 42 and the exhaust port 231, 351, 431 are each attached to the shield plate formed with a myriad of small pores of the size that the microwave can not pass to prevent the microwave from leaking, Rather than forming only one in consideration of the floor area of the drying chambers 20, 30, 40, the supply port is not only to provide a uniform supply of hot air, but also easy to manufacture and attach a shielding plate to prevent microwave leakage. It is preferable to form a plurality to be partitioned into a predetermined size for this purpose.

In addition, the upper and lower intervals of the distribution ports 21, 31, 31 'and 41 may be adjusted so that they can pass even when the thickness or volume thereof is different depending on the type of the drying object. The front and rear walls 20a and 40a and the partition walls 30a and 30b may be provided in a structure capable of elevating the upper side portions of the distribution ports within a predetermined range.

The conveyor 50 has a motor 51, rollers 52 and 52 ', which are respectively condensed to the front and rear ends of the base 10 and rotated by the driving of the motor, and are engaged with the rollers and upward. The portion that passes through the first to third drying chambers 20, 30 and 40 on the upper surface of the base and the downward portion is composed of a belt 53 rotated to pass through the lower portion of the base.

Power of the motor 51 is transmitted by the chain gear on the motor shaft and the chain 54 on the chain gear on the roller 52 'shaft to rotate the roller, the belt 53 is If a general flat belt is used or if hot air supplied to the interior of the drying chambers 20, 30, 40 through each supply port 22, 32, 42 is diffused more quickly, do.

The belt 53 is supported by the support roller 55 which is condensed to the upper surface of the base 10 at predetermined intervals, and the portion that is moved upwards in addition to the rollers 52, 52 'is the portion that is moved downward. The sagging is prevented from occurring by the guide rollers 56 which are condensed at predetermined intervals with different lengths in the lower part of the base.

The hot air blower 60 is installed below the base 10 and supplies hot air to the drying chambers 20, 30, and 40 through a supply pipe 61 connected to each of the supply ports 22, 32, and 42. Will be supplied to

Of course, the hot air supplied to each of the drying chambers 20, 30 and 40 may be supplied to one hot air fan 60. However, when it is necessary to supply hot air of different temperatures to the respective dry air chambers, the hot air air blowers may be installed. You may also

The magnetron 70 is provided with a plurality at predetermined intervals in positions not facing each other on the outer side of the two side walls 33 of the second drying chamber 30, the microwaves oscillated during operation is a dispersion member provided on the inner side of the both side walls It enters into the inside of the drying chamber through the waveguide 71 which is piped so as to penetrate through portions not facing each other of (34).

The magnetron 70 receives power through the transformer 82 and heat generated during operation of the transformer causes the cooling fan 83 to cool, so that the transformer and the cooling fan are proportional to the number of magnetrons installed. Is installed.

Although the waveguide 71 may use a circular or rectangular straight tube, in this case, when the microwave oscillated by the operation of the magnetron 70 passes through the inner end of the waveguide and enters the second drying chamber 30, it is almost diffused. Therefore, the range that is reflected by hitting the dispersion member 34 is relatively reduced, so that the dispersion efficiency of the microwave is reduced.

Therefore, the waveguide 71 has a spreading range when microwaves oscillate from the antenna of the magnetron 70, rather than a straight tube, and as the interval between the inner and outer ends 711 goes from the outer end 711 to the inner end 712, as shown in FIG. It is preferable to form a funnel inclined at an angle r of about 12-17 ° to be gradually widened.

In this case, since the microwaves oscillated by the operation of the magnetron 70 pass through the inner end 712 of the waveguide 71 and enter the second drying chamber 30, the microwaves are maximally diffused and thus impinge on the dispersion member 34. The area and the reflecting range are enlarged to greatly improve the dispersion and working efficiency of the microwave.

In addition, although the waveguide 71 shown in FIG. 5E has a rectangular shape, the waveguide 71 is not necessarily limited thereto and may be manufactured in a circular shape as necessary.

Shielding member 80 is made to have flexibility and resilience by coating a reflective material such as aluminum reflecting microwaves on one or both sides of the core material made of glass fiber, the upper end is integrally connected and the rest is compared with the upper and lower lengths It is divided into a plurality of narrow ribbons.

When the shielding member 80 is cut in proportion to the transverse lengths of the flow ports 21, 31, 31 ′ and 41, and the upper end portion is attached to each upper side of the flow port, the second The microwave dispersed in the drying chamber 30 is shielded from leaking to the outside through the distribution port, and the rest of the drying compartment is smoothly passed through the distribution ports because the remaining portion is narrowly divided.

Of course, in this process, the lower portion of the shielding member 80 is pushed in the direction of movement when the drying object passes, but when the drying object passes, it is immediately restored to its original state by its flexibility and restoring force, so the outlet is closed again. Is given.

On the other hand, although the water and residual heat discharged through each exhaust pipe 13 may be naturally discharged, it is preferable to force the discharge by installing a discharge fan for rapid drying and discharge.

The drying apparatus according to the embodiment of the present invention configured as described above is controlled by the control of a general automatic control system, and when the drying apparatus is operated, the drying object is placed on the carrying part of the rotating belt 53. do.

In this case, the object to be dried is moved into the first drying chamber 20 through the distribution port 21 while being moved by the rotating belt 53, and the inside of the first drying chamber is supplied with a bottom. Since hot air is supplied through the sphere 22, a primary drying step is performed in which the hot air heats the object to be dried and evaporates the moisture on the outer surface. The drying step is carried out through the distribution port 31. It continues until it is carried into the 2nd drying chamber 30. FIG.

Subsequently, in the first drying step, the object to be dried from which the moisture on the outer surface is removed is carried into the second drying chamber 30 and passes through the interior of the second drying chamber. At the same time as the hot air is supplied, the microwaves are oscillated by the operation of the magnetron 70 through the waveguide 71 and are evenly dispersed by the dispersion member 34. Moisture absorbed therein is performed by a secondary drying step in which all of the water molecules are evaporated and evaporated by frictional heat generated as the water molecules are vibrated by microwaves. Since it continues until it is brought into the third drying chamber 40 through it is dried up to the inside.

The object to be dried, which has undergone the second drying step, is carried into the third drying chamber 40 through the distribution port 31 ′ and passes through the inside of the third drying chamber. Since the hot air is supplied through), if some of the moisture escaped from the inside in the second drying step remains on the outer surface, a third drying step is performed to evaporate all of them. Since it continues until it is carried out from the 3rd drying chamber 30 to the carrying out part 12 through the sphere 41, a drying object is completely dried and carried out.

According to the operation as described above, 1 to be carried out in the process of passing through the drying chamber 20, 30, 40 in sequence only to put the object to be dried 11 on the carry-in part 11 side of the belt 53. The drying efficiency is drastically improved since it is completely dried by the third drying step and is continuously taken out to the carrying out portion 12. In addition, the moving speed of the object to be dried by the conveyor 50 is determined by the kind, volume or moisture. It may be adjusted according to the degree of content, of course, if there is no moisture on the outer surface or the moisture content is small, the first and third drying step may be omitted, and only the second drying step may be performed.

In addition, when the microwave used in the secondary drying step is irradiated to the dielectric, the rotation and vibration of the dipole in the molecule is generated to generate heat by friction, so in the case of bacteria, the water molecules inside vibrate to generate friction heat The internal temperature gradually rises, which causes bacteria to sterilize due to exothermic reactions, disrupts or destroys normal metabolic functions of cells, resulting in inhibition, stoppage and sterilization of bacterial growth, and at the same time RNA and DNA in cells These compounds are life-critical compounds, which can easily loosen or break hydrogen bonds in stable bonds between hydrogen bonds and a pair of OH groups, as well as disrupt the normal inheritance and reproduction of bacteria by inducing new arrangements of RNA and DNA. Because it has a biochemical action that makes it sterilized, especially when processing dry foods. It is characterized in that the use range is varied, such as being applied to dry various medical instruments, etc., which must be manufactured and managed in a sterilized state.

Such a drying apparatus according to the embodiment of the present invention is to go through the first to third drying step using hot air and microwave while moving the object to be dried, so that all the moisture absorbed inside as well as the outer surface is quickly evaporated and removed. There is a characteristic that complete drying, thereby achieving a drying efficiency as well as a significant increase in productivity.

In addition, since various pathogens are sterilized by the action of microwaves in the drying process, there is an advantage that the range of use is varied, such as being applied to the processing of dried foods or drying medical devices.
