Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rapid drying apparatus using microwave and hot air,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying device capable of rapidly drying food waste, and more particularly, to a drying device capable of rapidly drying food waste, The present invention relates to a device for drying food waste quickly by providing a three-dimensional stirring device for allowing a user to quickly dry food waste.

Food waste refers to the various types of garbage and residual food residues that arise from food production, distribution, and cooking processes in homes and restaurants. This amount increased to about 28% of municipal waste. Currently, a food waste disposal system is being implemented that pays disposal costs depending on the amount of food waste, and it is necessary to reduce the amount of food waste due to various environmental problems such as odor. In addition, food waste is more complicated than other garbage, and its influence on the environment is large. Therefore, studies are being conducted on methods of reducing food waste and easily treating it for various reasons such as protecting the living environment and improving living environment.

FIG. 1 is a table summarizing the processing methods, advantages and disadvantages of the conventional food waste drying apparatus. Conventional food garbage drying devices are classified into four types as hot air drying method, crush drying method, enzyme decomposition method and microwave method.

In the case of the hot air drying method, a drying method such as a waste food or the like is dried by using a hot air blower in a method widely used in general dryers. Such a hot air drying method is used in a small product because the product is easy to design with low failure, low product cost. However, there is a disadvantage that the drying time is long and the residue treatment is difficult.

In the pulverization and drying method, the food waste is crushed to a small size and hot air is used to remove moisture from the laundry. In case of the pulverization drying method, since it is pulverized and dried, the drying efficiency is higher than the general warm air drying method and the time required for drying is shorter. However, there arises a problem that the residue after grinding attaches to the grinding blade. Also, product design is complicated and product price is high.

In the case of the enzymatic pulverization method, the food waste is decomposed through the decomposition reaction of a specific enzyme to treat the food waste. In the case of such an enzyme crushing method, the microorganisms must be periodically replaced, and bad odors are generated. In addition, decomposition efficiency varies depending on the type of food waste.

Drying of food wastes using microwave is short in processing time and various food processing is possible. However, there is a problem that microwave shielding, applicability,

As described above, the food waste disposal apparatus has not yet developed a food waste disposal apparatus that can solve such problems. Also, in the case of a rapid drier, it is too expensive to be used at homes, farmhouses and restaurants, and takes a long time to dry.

In addition, the existing food garbage drying apparatus is the biggest problem to be used in the home, and odor is generated. Since the conventional food waste drying apparatus has a long processing time, it is impossible to exhaust both odor and water vapor generated during the processing. There is also a method of using a filter such as activated carbon to remove odors, but there is a disadvantage that periodic replacement is necessary because the efficiency of the filter decreases with time. Since there is a structure for sealing only from the outside of the food waste drying apparatus, there is a difficulty in preventing the leakage of the odor generated during the drying process.

In the method of injection, the food waste is processed by directly introducing general food or by adding an apparatus for grinding. When the general food is directly introduced, it is convenient for the user to use but the drying efficiency is lowered because the exposed surface area is small. After the grinding, the drying process is carried out through the apparatus. However, since other apparatuses are used in the grinding process, there is a problem in that the size of the entire food waste drying apparatus is increased and power consumption is increased. There is also a problem in the durability of the pulverizing apparatus.

The heat source also has a disadvantage in that the drying efficiency of the drying apparatus is higher than that of other heat sources (near infrared rays, microwave, laser, etc.) by using hot air with low efficiency and the drying time is long.

Microwave and the like are advantageous in that the drying time is shortened. However, in the conventional microwave devices, since the food waste is heated in a state in which the food waste is stacked in the container, There is a problem that it can not be removed quickly because it is blocked by the food waste.

An object of the present invention is to solve the above-mentioned problems of conventional food waste, and to maximize the convenience of use and drying efficiency of food waste that can be used for household use. In addition, the object of the present invention is to develop a rapid treatment apparatus for domestic household garbage which uses hot air and microwave simultaneously as a heat source.

In addition, the apparatus for drying food waste according to the present invention has an object of using the apparatus more easily, safely and effectively than other apparatus for drying food waste. It is intended to improve the drying efficiency by spraying the hot air directly onto the food waste, to continuously mix the food waste through the three-dimensional stirring action, and to change the area exposed to hot wind and microwave, thereby enabling quick and efficient drying.

In order to achieve the above object, the present invention provides an apparatus for quickly drying an object including moisture and an organic material, comprising: a drying space in which a material to be dried is received and dried; A microwave supply unit for supplying a microwave to the drying space to dry the laundry contained in the drying space; A hot air supply unit for supplying hot air to the drying space to dry the laundry contained in the drying space; An air outlet for discharging air containing steam from the drying space to the outside of the drying space; And a stirring part for repeatedly moving the drying object accommodated in the drying space in the vertical direction.

Unlike other food waste drying apparatuses, the household rapid food waste drying apparatus according to the present invention simultaneously uses microwave and hot air as a heat source for treating foods at a higher speed than other food waste drying apparatuses.

In order to feed the food, the food is not directly fed into the food waste drying device, but is put into the food waste drying container and put into the food waste drying device. In this case, the food waste can be introduced after the pulverization by the method proposed by the present invention or by various other methods before being put into the drying container. In the present invention, the food waste is directly crushed by the user by using a cutting board and a multi blade having a multi blade that can be placed on a drying cylinder. The pulverized food waste can be easily agitated by a three-dimensional stirring apparatus during the drying process. Also, since the surface area increases, the area exposed to the hot air and the microwave increases, thereby maximizing the drying efficiency. Of course, it is possible to crush using various methods such as crusher.

The heat source of the food waste drying apparatus according to the present invention uses hot air and microwave at the same time. Microwaves consist of magnetrons, high-voltage transformers, high-voltage diodes, high-voltage capacitors, and waveguides, just like conventional microwave ovens and dryers. The microwave means a frequency of about 1000 MHz to 30 GHz, and a typical household microwave uses a microwave of 2.4 GHz. The microwave generates rotational motion by molecular orientation in the moisture of the subject, and drying proceeds through intermolecular frictional heat. Unlike other drying methods, the microwave exhibits high drying efficiency because it directly acts on the moisture in the laundry. By exposing hot air to the surface of the object to be dried, it is possible to quickly remove water vapor on the surface which may occur during drying, and to rapidly remove water vapor in the air.

Hot air is put into food waste in a different way from other food waste drying equipment. The three-dimensional stirring blade which agitates the food waste can design the internal structure so that the hot air can be inputted into the blades itself, and the hot wind can be directly exposed to the food waste during the drying process. In particular, since the hot air discharged through the agitating blade through the food waste discharges the hot air to the contact surface with the agitating blade, the food waste can be dried at a higher efficiency than other dryers. In addition, since the food waste is crushed, the area exposed to the hot wind is wide, so that the drying efficiency is higher than other food waste drying apparatuses.

Even if the microwave and the hot air are used in combination, if the food waste is fixed in the drying chamber in one place, the efficiency of the drying process tends to be lowered. In addition, there is a drawback in that the moisture of the laundry is evaporated, and the laundry is fixed to the place where the laundry is located, which makes it difficult to post-treat. Therefore, the drying efficiency of the hot air can be improved by changing the position of the object to be dried and mixing it. It is possible to efficiently dry the food waste through the hot air blown out directly from the hot air discharge nozzle.

One of the biggest limitations in using food waste drying equipment is the odor generated during food drying. The odor generated in the food drying apparatus can be prevented by eliminating the water odor generated in the air while simultaneously removing water vapor in the air. Water vapor and odor can be discharged by connecting a blower or a compressor that can produce air pressure. The discharged water vapor and odor can be discharged to the bottom of the U-trap of the sewer to prevent backflow. In hot air removal, a structure for preventing backflow is attached. In this case, hot air, odor, and steam can pass in one direction but do not flow back to the other side. In addition, it can be attached to a drying box, and a deformable lid is used to connect the hot air outlet and the hot air-tight sealing device, thereby effectively removing the odor generated during the drying process of the food garbage drying device.

When there is sewage or sewage for the discharge of odor in the vicinity of the installation site of the food garbage drying device, it is effective to exhaust the odor by forcibly discharging the odor. However, if the installation site lacks the facility for such odor discharge, the odor filter can be used to remove the odor, such as other food waste dryer. When the filter is used as described above, the volume of the food waste drying apparatus can be reduced, and the apparatus can be used without any space for discharging odor. Also, there is no need to change the installation or work for installation. Thus, the malodor removing method can be selectively applied according to the user's environment.

By simultaneously using microwaves and hot air, the drying efficiency can be maximized. The microwave vibrates the moisture inside the object to be converted into water vapor. The generated water vapor is deposited inside the chamber or on the surface of the object to be dried, which can be dried using hot air. By removing the hot air, it is possible to remove the odor and steam generated in the food drying process. By removing the odor during the drying process, it is possible to efficiently solve the most problematic ambient environment and odor problem in the conventional household food waste drying apparatus.

The device for drying food garbage according to the present invention can simplify the product by simplifying various structures and reduce the manufacturing cost. Also, by using a combined heat source of microwave and hot air, moisture is effectively removed. The microwave is applied heat from the inside of the food garbage and the inside moisture moves to the surface. And the water that has moved to the surface is efficiently discharged into the water vapor in the air by the hot wind. The water vapor, together with the hot air, travels to the discharge device and is discharged or passed through the filter. As the process is repeated, the drying efficiency is further improved.

The three-dimensional stirring blades repeatedly mix food waste in the drying tub to continuously circulate hot air and areas exposed to microwaves. Continuous interaction is possible because the three-dimensional stirring blade continuously contacts the food waste. The agitating blade has an open shape through which hot air can pass, thus enabling efficient drying.

In addition, since each component can be decomposed and assembled, it is easy to clean and post-treat after drying food waste. The dried food waste can be processed by easily removing the food container. In addition, since the food drying drum rotates only the agitating blade in a fixed state, vibration and noise are less than those of a food waste drying apparatus using other stirring apparatuses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the accompanying drawings, embodiments of a rapid food garbage drying apparatus according to the present invention will be described below.

FIG. 2 is an operational flowchart of a rapid food waste drying apparatus using a three-dimensional stirrer 62 capable of inputting hot air and a combined heat source of microwave and hot air according to the present invention. First, after the drying cylinder 31 is taken out, the manual crushing board 41 is placed in the drying cylinder 31. Then, the drying tub 31 is placed on a flat surface, such as a sink, and then the food waste is crushed using a multi blade 43 composed of a plurality of blades. After all of the food waste has been put through manual pulverization, the food waste drying tub 31 is put into the food waste drying apparatus. After the drying tub 31 is inserted and food waste is put into the drying tub 31 of the food waste drying apparatus according to the present invention, a deformable upper blocking plate is connected and the drying tub 31 is closed. Then, the front part (165) is sealed and the drying process proceeds.

After the sealing is completed, hot air starts to be discharged and the stirring blade starts to rotate. Then, the magnetron 191 that emits microwaves starts to operate. These three parts work to dry food waste. At the same time, it is necessary to remove hot air and generated water vapor during the drying process. The hot air and water vapor discharge pump is operated and hot air and steam are discharged through the discharge path. During the course of drying, hot air is injected directly into the drying chamber 106 through the nozzles. The microwave is also emitted into the drying chamber 106 to heat the food waste from the inside. At this time, hot air, water vapor and odor generated in the drying process must be discharged to the outside.

After the drying is completed, the food garbage drying cylinder 31 is unlocked and then the cylinder is taken out first. Then, the dried food waste is discarded. Since the agitating blade can be attached and detached, it is possible to clean the food waste drying cylinder 31 and the agitating blade. After the post-treatment process is completed, the agitation blade is assembled again to assemble the food waste drying tub 31. Then, the next time the food waste is put into use, the drying process is carried out.

3 is a schematic view showing a drying cylinder 31 as one of the key components of a rapid food waste drying apparatus using a three-dimensional stirring apparatus 62 capable of inputting hot air and a combined heat source of microwave and hot air according to the present invention. The wall surface of the food garbage dryer tub 31 is cylindrical and the lower portion is elliptical. Therefore, the garbage is gravitated to the center by the shape. As the three-dimensional stirring apparatus 62 rotates, the food waste moves to the outside again. Therefore, the food garbage is continuously moved, and the food garbage is dried without being stagnated and fixed at one portion. The lower portion of the drying cylinder 31 is composed of three or four food waste drying basin lower fixing pins 34, a ratchet driving bearing joint plate 32 and a ratchet 33 for transferring the drying cylinder driving force. A three-dimensional stirring blade capable of introducing hot air is coupled into the drying cylinder 31. A ratchet structure 33 is connected to drive the stirring blade. The ratchet is transmitted to the driving force of the lower motor. Since the ratchet must be rotatable, the bearing joint plate 32 for ratcheting is used. And the food waste drying cylinder 31 should be placed on a flat plate for manual crushing. It is possible to use two or four food wastes drying basin lower fixing pins 34. The position of the drying tub 31 is fixed through the contact of the drying tub 31 with the shape of the interior of the drying tub 31. [

FIG. 4 is a schematic view showing a combination structure and a use method of the food waste drying tub 31 and the manual grinding board 41 for manual pulverization of the food waste according to the present invention. As shown in FIG. 4, the food waste drying cylinder 31 is engageable with the manual grinding board 41. The coupling is made through the manual finishing lower pin (42) for connecting the drying cylinder (31) on the back of the manual finishing board (41). In the pulverizing process, the drying tub 31 can be placed on various flat places such as a sink, a table and a table by the drying tub lower fixing pin 34 and can be manually pulverized. The food waste can be efficiently pulverized through the multi-blade 43 for improving the manual pulverizing efficiency. Multi-blades can be applied to the principle of leverage to reduce the force consumed in manual grinding in food milling process. The manual grinding knife rotating shaft 44 can be connected through the manual grinding knife rotating shaft connecting pin 45 as shown in FIG. Multi-blades can be used around the rotating shaft.

5 is a schematic view showing the multi-blade 43 in Fig. The multi-blade 43 is composed of a multiple blade 52 for efficient food grinding and a rubber plate 51 for grinding the food waste. On one side of the multiple blades 52, a rubber plate is connected by a pin shape 53 for connecting the rubber plates for the hair blades. A hole is formed in one side of the blade by punching, and a rubber plate 51 made of an elastic material (rubber, silicone, etc.) is sandwiched therebetween to feed the food into the drying cylinder. The multiple blades 52 are connected to one multi-blade handle 54. Each of the multi-blades 43 is disassemblable and can be assembled. Disassembly and assembling are possible, so that it is possible to remove food waste accumulated in the multi-blade 43 during pulverization. Of course, as for the pulverization of food waste, a pulverizer, a pulverizer and the like may be used as well as other food garbage dryer. As shown in FIG. 5, the multi-blade 43 has a manual pulverizing knife rotation shape 55, and the manual knife turning shaft 44 can be used as the central axis.

FIG. 6 is a schematic view showing a three-dimensional stirring apparatus 62 capable of improving the drying efficiency by mixing food in various directions inside the apparatus for drying garbage according to the present invention. The three-dimensional stirring device 62 is constituted by a plurality of sets of blades of the three-dimensional stirring device 62. In the illustrated embodiment, one set of agitating blades has an internal structure connecting three or four agitating blades with respective agitating blades. The three-dimensional stirring device 62 rotates about the central axis 61 of the three-dimensional stirring device. Particularly, the inner stirring blade 63 of the three-dimensional stirring device 62 is shaped like a bottom shape so as to maintain a tolerance of the same distance as the bottom shape of the food garbage drying tub 31 as shown in FIG. As shown in FIG. 6, the cross-section is streamlined so that the food waste 64 at the bottom of the bottom of the food waste drying tub 31 can be swept as the inner stirring blade 63 rotates. The other portion of the three-dimensional stirring device 62 except for the inner stirring rod is formed in a cylinder shape because it does not contact the bottom. Each of the agitating blades may consist of a bladder for hot air transfer and an internal structure for structural support.

The agitating blades are arranged in a circular shape as seen in the plan view of Fig. Therefore, the three-dimensional stirring device 62 rotates and not only rotates the food waste but also mixes the food waste with the upper and lower parts. The inner stirring blade 63 first comes into contact with the food garbage, moves on the stirring blade, and the food garbage falls again. The food garbage that has fallen is again brought into contact with the next stirring blade, and is exposed to hot air. Such repetitive movement and hot air exposure can maximize the drying efficiency. And the agitating blades have to be rotated but fixed in the case of the drying cylinder 31. [ Therefore, the drying cylinder 31 can rotate only the three-dimensional stirring apparatus 62 in a fixed state by using the bearing joint plate or the bearing 32 for driving the ratchet.

7 is a schematic view showing a method of connecting the three-dimensional stirring apparatus 62 of FIG. 6 with the drying cylinder 31 and transmitting the driving force. First, the central axis 61 of the three-dimensional stirring apparatus is connected to a connecting device 71 for stirring blade connection. The connecting shaft 71 is connected to the bearing joint plate 32 for ratchet driving. The drying cylinder 31 may be fixed through the bearing joint plate 32 and a connecting device 71 for connecting the stirring blade connected to the ratchet 33 for transmitting driving force to the drying cylinder 31 is connected. The ratchet 33 for transmitting the drive force to the drying cylinder is connected to the lower ratchet 73 for transmitting the driving force of the lower portion. The lower ratchet 73 for transmitting driving force is connected to a motor 74 for generating driving force. The pin 72 for connection with the three-dimensional stirring device 62 is constituted by a triangle to match the number of agitating blades. And can be coupled with the three-dimensional stirring device 62 in a fitting manner. Also, the pin 72 for connection and the three-dimensional stirring device 62 can be fitted in three planes. Since there is no directionality, it can be inserted in any direction.

8 is a schematic view showing the assembling method according to FIG. 7 in a front view. The three-dimensional stirring apparatus 62 is located at the uppermost position in the connection order. The drying cylinder 31, the ratchet driving bearing joint plate 32, the ratchet 33 for transmitting driving force to the drying cylinder side, the lower ratchet 73 for transmitting driving force, and the motor 74 for generating driving force are connected in this order do. In the case of the drying cylinder 31, it is fixed. The driving force starts from the motor 74 and is transmitted to the connecting device 71 for connection between the lower ratchet 73 and the upper ratchet 33 and the three-dimensional stirring device 62 to rotate the three-dimensional stirring device 62 . The three-dimensional stirring device 62 and the connecting device 71 are connected to the connecting pin 72 for connection as shown in the right side of FIG. The connecting device 71 is connected to the groove of the center shaft 61 of the three-dimensional stirring device in a shape of a letter. The connection pin 72 moves upward / downward and then moves in parallel. Here, the connection pin movement path for the agitating blade connection is indicated by 82. [ And can be fixed using a ball joint 81 for connecting the stirring blade so as to be fixed after being moved in the shape of a figure. The equilibrium movement is in the opposite direction to the rotation direction, so that the three-dimensional stirring apparatus 62 can be used without being released even if it is rotated. The separation proceeds in the opposite direction to the mounting of the three-dimensional stirring apparatus 62. [

The food waste drying tub 31 must be fixed and the ratchet 33 connected to the drying tub 31 and the ratchet 73 connected to the motor 74 must be connected to each other. This can be connected through the drying tub insertion guide 91 inside the food waste drying tub 31 and the lower portion 92 of the food waste disposal apparatus. An example of the connection method is shown schematically in FIG. As shown in FIG. 9, the drying tub insertion guide 91 and the lower portion 92 of the food garbage disposal apparatus are connected to each other in the food waste drying tub 31. The food garbage drying cylinder 31 and the lower ratchet 73 for transmitting driving force are connected through the connecting portion. Also, the food waste drying tub 31 is fixed so as not to move.

A method of putting the food waste drying tub 31 is as shown in Fig. And the food garbage drying tub 31 is inserted along the drying tub insertion guide 91. [ Since the drying cylinder 31 is inserted along the guides 91, the movement is easy. But fixing is not perfect. In order to prevent rotation after inserting the food garbage drying bin 31, one food garbage drying bin lower fixing pin 34 and two food garbage drying bin lower position adjusting pins 35 are used under the drying bin 31 . Of course, the number of pins 34, 35 is adjustable. A lower fixing pin 34 is located at the innermost position and a drying drum fixing pin connection device 93 is installed at a lower portion of the drying tub 31 so that the fixing pin 34 can be inserted, have. When two pins are connected, it is only possible to rotate around the pin. The other two positioning pins (35) are located on the opposite side of the drying cylinder fixing pin connecting device (93). The two positioning pins 35 are deformable and elastically joined in the radial direction as shown in Fig. The elastic structure of Fig. 9 has an oblique shape and can move a small amount in the radial direction. It is possible to easily locate the drying tub 31 when it is put into the food waste drying apparatus. In order to completely fix the drying tub 31, it is necessary to fix the movement in the direction (longitudinal direction) in which the drying tub 31 is inserted. For this purpose, the drying tub 31 must be placed in the lower portion 92 of the food waste disposal apparatus, and then a pressing force from above must be applied.

10 is a schematic view showing a method of introducing hot air into the drying cylinder 31 and a method of discharging hot air. In one embodiment, hot air generated by the hot air generating device 164 can be introduced into the drying tub 31 by the hot air introducing tube 101. The hot air is introduced into the hot air diffuser 103 from the hot air introducing tube 101. The hot air is dispersed in the dispersing device 103 by the number of nozzles. In Fig. 10, three pieces are used as the number of stirring blades. The hot air is injected into the hot air introducing nozzle 105 from the dispersing device 103 and hot air is introduced into the food waste in the drying container through the nozzle. Each nozzle is located in the hot air inlet connecting plate 104 located above the drying chamber 106.

FIG. 11 is a schematic view showing the hot air injection method and the structure of FIG. 11 is a side view showing a method of introducing hot air. The nozzles may be arranged to have a vertical rotation angle and a horizontal rotation angle as shown in FIG. As the hot air is concentrated and discharged, the drying efficiency can be maximized through the interaction with the rotation of the stirring blade. In the case of the horizontal rotation angle, since the blades of the agitating device 62 are rotated as shown in Fig. 6 (refer to reference numeral 107), they are rotated in parallel with each other. And in the case of a nozzle, it is located inside the food waste drying cylinder 108. The nozzles are connected to the hot air dispersing device 103 as shown in the lower right part of Fig. In the case of the nozzle, the hot air inlet nozzle 109 is connected to the nozzle end so as to discharge the concentrated hot air. Depending on the height (h) and shape of the equilibrium portion, the shape of the hot air discharge may vary. In order to maximize the interaction with the agitating blade, it is preferable to discharge hot air strongly and concentratedly.

12 is a schematic view of an apparatus and method for discharging water vapor and odor in a food waste drying apparatus according to the present invention. Hot air discharge creates pressure from the outside to remove hot air inside the drying chamber 106. Hot air and steam generated during drying are low in density due to high temperature. It is therefore effective to remove hot air from above. 12 shows a tube connected to the detachable tube 122 from the detachable outlet 123 for hot air discharge and connected to the hot air outlet joint 121 and connected to the hot air discharge tube 102 and discharged therefrom. 12 is a schematic view showing an integrated hot air discharge method. The hot air is discharged in an integrated fashion without being divided into a plurality of tubes. 13 is a cross-sectional view showing the hot air discharge method of FIG. The drying chamber side hot air discharge path 131 is located in the drying chamber side blocking plate 125 and the hot air is discharged through the path.

FIG. 14 is a schematic view showing an annular lid 141 and a structure thereof for enabling efficient hot air discharge of the food waste drying apparatus according to the present invention. As shown in FIG. 14, the deformable annular lid 141 can be used to connect and seal the drying tub 31 and the hot air outlet. The annular lid 141 has a funnel shape that is downward biased as shown in Fig. In the case of such a structure, when the deformable annular lid knob 142 is tilted downward, the center of the annular lid 141 instantaneously expands to cause deformation and can be turned upwards. This is referred to as shape 143 after deforming the annular lid. Then, a post-deformation hot air contact point 144 is formed and connected to the drying chamber side blocking plate 125. The cross section is the same as the bottom right of Fig. When the annular lid 141 faces downward, it can be fitted to the drying cylinder 31 through the annular lid inner blocking plate 145. And is deformed (tilted) outwardly through the annular lid outer closure plate 146 after deformation.

FIG. 15 is a schematic view showing a cross-sectional structure and a connection method of the annular lid 141 which enables the efficient hot air discharge of FIG. When the drying tub 31 is inserted with the lid inserted, it is positioned as shown in the left side of Fig. At this time, when the handle 142 is turned down, the lid 141 is deformed to form a hot air outlet contact point 144 after the annular lid is deformed as shown in the right drawing, so that it comes into contact with the drying chamber side blocking plate 125. As shown in Fig. 15, a space for injecting hot air (nozzle position) is formed at the central portion, and a space for exhausting hot air is provided at the outer portion. A separate outlet 123 for hot air discharge may be located above the hot air outlet. The shape of the deformable annular lid after deformation is the same as the reference numeral 151. Also, the food waste annular lid 141 can prevent the food waste from being passed out of the drying tub 31 by the agitating blade 63 during the drying process.

16 is a schematic view showing the shape of the front part of the food waste drying apparatus according to the present invention. The food waste drying apparatus (drying apparatus) according to the present invention can insert and remove the food waste drying tub 31 by opening and closing a front door 165 on an elliptical cross section. Since hot air and microwaves are used in the drying process of the food garbage, it is necessary to seal the hot wind and the microwave in the front door (165). In particular, microwaves require complete shielding because they can cause many problems when exposed directly to the human body. For microwave sealing / shielding, a structure using a 90 degree bent pin used in conventional microwave ovens (microwave oven) (utility model 1986-0012035, etc.) can be used. By using the rectilinear portion as it is, the structure used for sealing can be simplified, and the parts used in the conventional microwave oven can be used as it is. In the case of the front part door 165, by using the front part door rotation shaft and the connecting pin 167 so as to make the rotation axis inside the front part door 165 as shown in FIG. 16, Portion 166. < / RTI > If the space is sealed with rubber or silicone, the odor and microwave can be sealed.

The overall structure of the food waste drying apparatus according to the present invention may be such that a food waste drying apparatus controller 162 is attached to the upper portion 161 of the food waste drying apparatus as shown in FIG. 16, thereby controlling and using the entire food waste drying apparatus. The magnetron 191 for microwave generation and various electronic products and the drying chamber 106 may be located inside the outer wall 163 of the food waste drying apparatus. A lower portion 92 of the food garbage disposal apparatus is located inside and a lower end portion 169 of the food garbage drying apparatus is located outside the food garbage drying apparatus. And a height adjustment dial 168 for adjusting the height of the food waste drying device is disposed therebelow. A hot air generator 164 and a hot air discharge device 181 may be positioned on the opposite side of the front door 165.

17 is a schematic view of an apparatus for adjusting the overall height and equilibrium state of a product of a food waste drying apparatus according to the present invention. The entire structure of the food waste drying device can be installed in various places such as inside of the sink, and above. Since the internal stirring blade rotates, it should be positioned in the proper position and leveled. Therefore, a height adjusting dial 168 for height adjustment and vibration absorption can be attached to the lower portion of the food waste drying apparatus. Three, four, or more, and the height can be adjusted by simply turning it. In addition, the lower part is made of a composite material for impact absorption, which can bring about height adjustment, vibration absorption, and noise reduction effect.

18 is a schematic view showing an apparatus and method for generating hot air and removing water vapor and odor in a food waste drying apparatus according to the present invention. The removal of water vapor and odor can be roughly divided into two methods. First, it removes water vapor and odor through forced exhaust. The water vapor and odor generated in the drying tub 31 and the drying chamber 106 are connected to the device 181 for discharging the hot air through the hot air discharge tube 102 inside the food waste drying apparatus. The apparatus 181 for generating hot air generates a pressure difference and takes out water vapor and odor in the drying tub through the hot air discharge pipe 182 to the outside of the food waste drying apparatus. The hot air discharge pipe 182 can be connected to the sewerage and U-trap underneath. When removing steam and odor through forced exhaust, the product should be installed near the bottom of the sewer and U-trap that can handle the discharged steam and odor.

As another method, it is possible to treat water vapor and odor by using a malodor removing filter 184 such as a conventional food waste drying apparatus. In this case, the water vapor is condensed and evaporated, and in the case of an odor, it can be passed through a malodor removing filter 184 composed of activated carbon or the like. The appearance of the odor eliminating filter 184 can be improved by using the odor eliminating filter case 183.

19 is a schematic view showing the internal structure and the construction of the food waste drying apparatus according to the present invention from the top. 19, the internal configuration and the position of each component can be arranged. The sectional shape of the product is an elliptical shape shifted to one side as described above. This offset is used to straighten the enclosed area 192 of the front portion. Of course, oval shapes other than straight lines can be used, and rectangular shapes such as conventional microwave ovens (microwave ovens) can also be used. On the right side, there are a magnetron 191 for generating a microwave, a hot air generating device 164 for constituting a fan and a heat source, and a hot air discharging device 181. And a control panel, a transformer, a capacitor, a diode, and the like for driving and controlling the product can be disposed therebetween. And a U-shaped microwave sealing (shielding) region 193 is formed in the inside. The microwave sealing region 193 refers to an internal heating chamber that is heated by a microwave generated through the magnetron 191. In general, metal shielding is used. Even in the food waste drying apparatus, the influence of heating by the microwave is limited within the drying chamber 106 and inside the microwave sealing region 193. And a lower portion 92 of the food garbage disposing device for putting the drying tub 31 and the drying tub 31 therein is located inside. The front portion, through which the user can put the food waste drying tub 31, is shielded by the front closed region 192. Above the drying chamber 106 is disposed an apparatus 181 for hot air supply and discharge. 19, the hot air supply tube 102 and the hot air supply tube 101 generate a connection passage that can not pass through the microwave in the microwave hermetically sealed region 193, Generating device 164 and the device 181 for hot air discharge. Although not shown in FIG. 17, a ratchet structure and a motor and a lower portion 92 of the food garbage disposing device are located below the drying tub 31 for fixing the drying tub 31, driving the three-dimensional stirring blade, and the like.

The malodor and microwave sealing of the food waste drying apparatus according to the present invention is located in the space between the front door 165 and the trash drying device body. In case of malodor, the leakage of odor can be prevented through the front part (165). The drying chamber 106 is connected to the hot air discharge port so that hot air exits only to this portion. The microwaves may be generated through the magnetron 191 and then introduced into the microwave sealing (shielding) region 193 only. The front door 165, into which the drying cylinder 31 can be inserted, is used for sealing / shielding the microwave used in the microwave oven (microwave oven) in the front closed area 192, It is possible to seal by using a structure using a 90-degree bent pin used in a microwave oven (microwave oven).

FIG. 20 is a schematic view showing the outer appearance of a rapid three-dimensional food waste drying apparatus using a three-dimensional stirrer capable of introducing hot air and a combined heat source of microwave and hot air. Both the top and bottom and the internal structure are changeable. Of course, like a conventional microwave oven, a rectangular shape is possible, and a cylindrical shape is also possible.

21 is a schematic view for explaining a method of using the food waste drying apparatus of Fig. First, the front door 165 is opened and the drying cylinder 31 is taken out. After the drying tub 31 is taken out, the drying tub 31 is placed on a flat surface, and a manual finishing board is placed on the drying tub 31. Then, the food waste is manually pulverized by using the multi blade (43) enclosed with the product. At this time, when the food waste is pulverized and then put in, the drying efficiency is greatly improved. It is difficult to crush bones and solid food waste, so it is helpful to improve the product life by treating separately. Manual grinding can be easily performed by using the manual grinding knife rotating shaft in the manual grinding.

The food is manually pulverized, and the drying tub 31 is covered with a deformable annular lid 141 and put into the food waste. At this time, the lower drying basin 31 should be connected to the lower portion 92 of the food waste disposal apparatus. It is possible to prevent the hot air from remaining in one place by making the contact point with the drying chamber side blocking plate 125 by removing the handle 142 of the deformable annular lid after inserting the drying tub 31, .

In the drying process, the drying time can be determined according to the amount of food waste depending on the amount of food waste, and the amount of food waste can be predicted by measuring the weight of the food waste drying container 31 and the drying time can be determined accordingly have. If we have a weighing system in this way, the drying process can be terminated after the weight has decreased by a certain percentage (generally 85% moisture loss). During the drying process, the introduction of hot air is the first to prevent sticking of the agitation blade and food waste. And microwave can be operated to maximize drying efficiency. Also, the temperature of the food garbage drying tub 31 and the temperature of the food garbage are measured. When the temperature of the food garbage is raised too high, the microwave can be turned off to prevent the food from being carbonized.

After drying is completed, the food waste drying tub 31 can be taken out and the dried food waste can be discarded. The drying cylinder 31 is taken out and the stirring blade can be disassembled and cleaned. The interior of the food waste drying tub 31 is also washable. In the case of agitating blades, each agitating blade blade can be made assembled and made washable for each part.

Drying pails and upper clogging plates exposed to microwaves, a food waste drying unit lower part, and a stirring blade may be made of a polyethylene material which hardly absorbs microwaves. The microwave shielding area should be machined so that there are no sharp edges on the corners. The sharp edges of the metal are caused by sparks when exposed to microwaves. Also, in the case of microwave chambers, microwaves are not exposed when holes are made from 1/10 to 1/5 (12 mm to 24 mm) of the microwave wavelength (120 mm). Therefore, the chamber, the hot air inlet portion, and the discharge portion may be manufactured in this size.
