Description

Dryer for garbage}

The present invention relates to a food waste dryer, by quickly drying, sterilizing, and lightening food waste containing a lot of moisture from the discharging stage at home, small, large restaurants, and group catering centers. By reducing the amount of waste and waste to be collected, it has a purpose and structure to quickly block the occurrence of secondary environmental pollution (surrounding pollution due to leachate, odor due to decay, difficulty in collection and transportation, etc.) and increase resource recycling.

The inventors have been devised and disclosed in Patent Registration No. 731904, Patent Registration No. 874164, and Utility Model Registration No. 440555. However, although the previously disclosed food waste dryer has a relatively simple structure and has an advantage in terms of economical production and use, the evaporation time increases due to the large amount of waste water accumulated in the large amount of food waste such as large restaurants and group catering centers. It is very difficult for hot air to reach the middle part of the accumulated food waste, so the overall drying is slow. Therefore, the temperature and humidity tend to be perishable for a long time, and accordingly, a considerable amount of long-term odor and partial decay and incompleteness of the middle part of the accumulated food waste As drying occurs, more drying time is required, and overheating energy consumption occurs. In other words, some disadvantages have been pointed out in terms of drying efficiency such as drying time, and moreover, when the Ministry of Agriculture and Food took effect on October 1, 2017, when recycling leftover food waste, the moisture content should be 14% or less, and heated at 100℃ or higher for 30 minutes or more. As related laws such as treatment have been revised and announced, it is necessary to improve the performance of food waste dryers that can be safely dried even at high temperatures.

The present invention was proposed to solve the disadvantages of the food waste dryer according to the prior art, and improved the food waste dryer disclosed by the inventors of the above patent registration 731904, patent registration 874164, and utility model registration 440555. will be.

The object of the present invention is to shorten the drying time safely and quickly until reaching the appropriate standard and temperature required for the particularly revised related laws and drying treatment of large amounts of food waste, and another object of the present invention is applied for drying. By placing upper and lower control barriers on the heater and the newly applied upper and lower outlets, and controlling both or each appropriately, power waste is reduced and the device is not overwhelmed. In particular, food waste is relatively low in the lower part. Since it contains a lot of wastewater and moisture, it quickly dehydrates and discharges a lot of wastewater contained in food waste to the outside, significantly shortening the drying time, improving drying efficiency and thermal energy efficiency, and moreover, quality leftover food. The goal is to provide a food waste dryer that quickly dries garbage to produce high-quality food waste recycling resources.

The food waste dryer according to the present invention; Including a stirring rod and stirring blades that allow easy transportation of the dried food garbage when it is collected and discharged, and then promptly dehydrates and discharges the wastewater to the sewer before heating and drying. A cylindrical body; A blower disposed in communication with an upper side of the cylindrical body; A duct including a first circulation passage and a second circulation passage through which hot air circulation is connected from the blower to the upper and lower portions, and an upper discharge port which is a passage through which odor and water vapor generated by hot air drying are discharged; A deodorizing container connector for exchanging, removing and attaching the odor removal container to the upper outlet; An ultraviolet sterilization lamp for sterilizing spoilage and harmful bacteria of food waste inside the cylindrical body, which is disposed in communication with another side of the upper portion of the cylindrical body; A sensing sensor for sensing temperature, pressure, and humidity inside the cylindrical body is provided; And a mesh compartment for supporting food waste disposed in communication with the lower side of the cylindrical body; The high-temperature hot air extends to the second circulation passage below the mesh compartment and connects, and the sewage of the introduced food waste passes through the mesh compartment by the action of the stirring blades included in the cylindrical body, and quickly dewaters the wastewater into the sewage pipe. After discharge is made and sufficiently discharged, internal circulation of high-temperature hot air is performed under the mesh compartment, in which case, the stirring blade operation continues inside the cylindrical body from the lower part of the cylindrical body to the inside of the upper part of the cylindrical body. It helps a lot in circulation. However, since debris and the like are trapped in the mesh compartment and dry foreign matter is blocked, the function of the ventilation circulation at the lower side may be deteriorated. Therefore, it is natural that it must be easy to attach and detach to the outside for easy cleaning from time to time. In addition, the lower outlet is disposed to protect the mesh compartment; At the same time, it facilitates the connection of discharging food waste to the sewage pipe, and at the same time, it is connected so that hot air circulation to the lower part is well established under the mesh compartment, and when the dried waste is collected and transported to the outside, it is connected to the collection box. There are three connection functions. Accordingly, the lower discharge port includes a sewage pipe connector that helps to connect with the sewage pipe connection lake so that food waste and wastewater are easily discharged to the sewage pipe; A lower ventilation connector connecting the lower hot air circulation under the mesh compartment; Includes a blocking plate at the entrance of the collection bin to easily put it in the collection bin when the dried garbage is transported outside. The collection bin entrance blocking plate is used by opening the dried garbage only when the external collection bin is inserted. Preferably, a separate upper control blocking plate is placed between the upper discharge port and the deodorization tube connector; In the lower side, a separate lower control barrier plate was also placed between the lower outlet for discharging sewage and dried waste and the sewer pipe connector; In addition, each of the heat transfer heaters is internally mounted in the first circulation passage and the second circulation passage of the duct connected from the blower. Therefore, through the information of the composite sensor, the two electric heaters and the upper and lower control barrier plates can be selectively controlled or respectively. Therefore, from the beginning of food waste input, the waste wastewater is quickly discharged to the outside, and then the hot air circulation drying is performed while increasing the internal temperature by quickly blocking the external cold air, reducing the loss of hot air to the outside, and increasing the internal pressure and drying temperature. Drying efficiency can be quickly increased, and drying can be proceeded with safe and appropriate control. In addition, when the danger of high temperature and high pressure increase occurs when the food waste dryer is operated for a long time, the temperature, pressure, and humidity sensing sensors can be selectively turned on/off to prevent and prevent the danger. A stirring motor and a control unit were placed on the outer side to input control operation.

According to the present invention, after the food waste is put into the safety inlet, a significant amount of food waste and water contained in the food waste is first dehydrated from the beginning through agitation operation, so that the waste water that accumulates in the dryer is deliberately collected in the lower part and unnecessarily heated and dried. Instead, it discharges wastewater sufficiently quickly to the sewage pipe connector through the mesh compartment and the lower discharge port arranged in communication with the lower side. Therefore, power consumption and waste of heat energy more than necessary are reduced, and then both the upper and lower control barrier plates are closed, and the two electric heaters, blowers, and stirring operations are operated to proceed with full-fledged drying, which is the initial stage of food waste input. The pressure and temperature inside the food waste dryer are rapidly increased from the start. At this time, the inputted food waste is continuously stirred, and the hot air is continuously circulated up and down quickly, making it evenly mixed with the wet food waste, simultaneously up and down. The hot air heating and drying are evenly achieved. Therefore, it is possible to eliminate unnecessary waste of preheating power for a long time, and to reduce the waste of high-temperature hot air energy flowing out. Furthermore, through the complex sensing sensor, the pre-set internal temperature, pressure, and humidity are judged to proceed with drying of the food waste.The two built-in electric heaters and the upper and lower parts are prevented from the danger of internal high temperature and high pressure during drying operation. It is natural that the overall safety of use and drying efficiency of the dryer are more convenient and improved because all or each of the control barriers are controlled to prevent or prevent danger. In addition, it is for connection of three functions, such as a passage for discharging wastewater from food waste to the sewer through the lower outlet, a lower connection passage for hot air under the mesh compartment, and a passage for collecting dried food waste. It is used, but simplifies the complex installation structure, which is advantageous for the manufacture and management of the dryer. In particular, when the dried food waste is transported to the outside by using the stirring function, it is easy to put it into the container. , Close all of the lower control barrier plates to block access to various pests, and operate the UV sterilization lamp installed inside the upper side to reduce the occurrence of odor and surrounding pollution by killing internal decay bacteria and harmful bacteria in advance. It has the effect of increasing resource recycling by producing high-quality resources by reducing the spoilage of leftover food waste as quickly as possible.

In the drawings, the food waste dryer according to the present invention is denoted by 100. In FIGS. 1 and 2, the food waste dryer 100 includes left and right plates 1 and 2 provided separately, a control unit 5 on which various switches are disposed, and a stirring motor 6. The food waste dryer 100 is a composite sensing sensor that senses temperature, pressure, and humidity disposed in communication with the food waste safety inlet 7 disposed in communication with the cylindrical body 11 and the upper portion of the cylindrical body 11 (8) And ultraviolet sterilization lamp (15) that kills spoilage and harmful bacteria, and separates and dehydrates the wastewater contained in a large amount of accumulated food waste in advance, blows hot air into the inside circulating evenly, and dry food A stirring rod 12 and a plurality of stirring blades 13 to facilitate external garbage collection, a blower 16 disposed in communication with the other side of the upper portion of the cylindrical body 11, and the blower 16 The arranged duct 21, the duct 21 includes three passages, one of which is an upper outlet 17 for discharging water vapor to the outside, and the upper outlet 17 has an upper outlet 17 for removing odor. A deodorizing container 18 and a deodorizing container connector 19 that facilitates detachment and attachment when cleaning and exchanging the odor removal container 18 are connected, and the upper discharge port 17 and the deodorizing container connector 19 Between ), there is an upper control barrier plate 20. In addition, the other two passages have an upper first circulation passage 23 and a lower second circulation passage 24 for circulating the hot air into the cylindrical body 11. In addition, it is composed of a heat transfer heater (23a) disposed in the upper first circulation passage (23) and the heat transfer heater (24a) disposed in the lower second circulation passage (24), the first circulation passage (23) is the cylindrical body (11) It extends to the upper center so that hot air circulates well from the upper side to the inner space of the lower side, and the second circulation passage 24 is well circulated from the lower side of the cylindrical body 11 to the inner space of the upper side. It includes a lower air blow connector 30 and a lower air blow connector 35 that extends and induces the lower air so as to be maintained. On the other hand, there is a mesh compartment 25 that supports food waste disposed in communication with the lower portion of the cylindrical body 11, the mesh compartment 25 separates and discharges wastewater contained in the food waste, sewage pipe connection lake 34 ), and also serves as a hot air circulation passage into the cylindrical body 11. And there is a lower outlet (26) that is arranged to protect the mesh compartment, the lower outlet (26) is especially for three functional connections, the first of which is a connection with the sewage pipe connection lake (34) through which sewage is drained. A sewage pipe connector (27) that helps easily, and the second is, the lower ventilation connector (35) is connected under the mesh compartment (25) to help the lower hot air circulation inducement connection, and the third is to dry All of the collection bin entrance blocking plates (33) are included to help connect and insert the used food waste into the external bin. Accordingly, the lower discharge port 26 includes a passage for discharging the food waste wastewater to the sewer, a lower hot air circulation connection passage, and an external transport collection passage for dried food waste, that is, all three passages are the lower discharge port. It is gathered at (26). In addition, a lower control barrier plate 20a is also disposed between the lower outlet 26 and the sewer pipe connector 27. Preferably, when the dried food waste is put into and transported to the outside container, the collection passage is opened by only opening the collection box entrance blocking plate 33 regardless of whether the lower ventilation connector 35 and the lower control blocking plate 20a are opened or closed. It has a simple structure that can be used. On the other hand, the control unit 5 senses the temperature, pressure, and humidity with the complex sensing sensor 8, so that the upper and lower control barrier plates 20 and 20a and the electric heaters 23a and 24a are all or each Efficiently controlled, but looking at the specific embodiments, the drying method is largely in two ways, depending on the installation location where the food waste dryer 100 can be installed, and the other is the installation location where there is no risk. The control method can be selected. First, the control method in a place where there is a risk is safe, since most of the food waste containing a significant amount of sewage is put into the dryer 100, the upper control barrier plate 20 is Closed, the lower control blocking plate (20a) is in the open state, the stirring operation is in progress, and the sewage is discharged to the sewage pipe connector (27) of the lower outlet (26) for about 10 minutes, and then, again, the upper and lower control Closing all of the blocking plates 20 and 20a, and operating the blower 16 and the two electric heaters 23a and 24a. At this time, as the internal temperature of the cylindrical body 11 starts to reach 45°C, the When the lower control barrier plate 20a is closed, only the upper control barrier plate 20 is opened to remove odor to the deodorization tank 18 and send water vapor to the outside, while the two electric heaters 23a and 24a ) Properly controlled, and after drying proceeds while maintaining the internal temperature of the cylindrical body 11 at 60 to 70° C., when the humidity inside the cylindrical body 11 is within 14%, the upper and lower control barrier plates 20, With all 20a) closed, the internal temperature of the cylindrical body 11 is maintained at 100°C or higher for 30 minutes, and then the two electric heaters 23a and 24a, stirring, and blower operation are all stopped. However, when new wastewater is generated due to food waste being introduced in the middle, the lower control barrier plate 20a is opened and closed for 5 minutes after discharging the wastewater, and then it is kept in the control state again. In the control method of, first, after inputting the operating time as an input amount of food waste in units of 1 hour, after inputting the food waste, in a state in which sewage was discharged for 10 minutes, the upper and lower control barrier plates 20 and 20a were removed. Close all, and as in the first method, when the internal temperature reaches 45°C, only the upper control barrier plate 20 is opened to discharge odor and water vapor into the deodorizing container 18, and then the internal temperature of the cylindrical body is 60 to 70°C. Drying is carried out while maintaining, and drying is operated until the end of the input time.If new food waste is introduced in the middle, likewise, when new food waste is introduced, only the lower control barrier plate 20a is opened for 5 minutes, and then the lower control barrier plate 20a is closed again and the rest Drying operation is completed until the end of the input time. At this time, the UV sterilization lamp 15 and the preset time are continuously operated without change. Naturally, the dry matter collected and transported by the second control method has a moisture content of 14% or less in the second process, and it is natural that it is used for resource recycling after passing all the heating conditions at 100°C for 30 minutes again. Therefore, it is consumed by a series of control operations, such as stopping the entry of cold air from outside early, and terminating the operation of the food waste dryer 100 when the temperature and humidity inside the cylindrical body 11 reach a set target. It reduces power waste, and the control unit opens all the upper and lower control barrier plates or forcibly stops the operation of the electric heater when the high temperature and high pressure reach a higher risk level than the set maximum, but the blower continues to operate regardless of this, All of these control operations, such as restarting when it reaches the normal range again, prevents and prevents the risk of high temperature and high pressure in advance, and furthermore, the continuous stirring operation of the stirring rod 12 and the stirring blade 13 The wastewater contained in the food waste is contained in the cylindrical body 11 from the beginning of the food waste input through the lower outlet 26 so as not to dry up to the wastewater stored unnecessarily, and the mesh compartment 25 and the lower outlet 26 ) And through the sewage pipe connector 27, a significant amount of wastewater is quickly separated and discharged to the outside of the cylindrical body 11. In addition, control transfer from the control unit to the upper and lower control barrier plates 20 and 20a is transmitted to the upper and lower control transfer rods 32 and 32a. Therefore, the drying process in a state where both the upper and lower control barrier plates are closed completely blocks the inflow of cold air into the cylindrical body 11 from the beginning, and the blower 16 and the first circulation passage 23 ) To induce the high-temperature hot air circulated from the top to the bottom, and at this time, the high-temperature hot air is evenly transferred from the top to the bottom by the stirring operation, and the lower blowing connection pipe 30 of the second circulation passage 24 ) And the high-temperature hot air that has been extended to the bottom of the mesh compartment 25 through the lower ventilation connector 35, and the cylindrical shape passing through the mesh compartment 25 through agitation action and internal hot air suction circulation action of the blower 16 It is guided to the inside of the lower part of the main body 11. In particular, since food waste contains a relatively large amount of wastewater and moisture in the lower part, the high-temperature hot air circulation to the lower portion of the cylindrical body 11 is emphasized, and high-temperature hot air is evenly distributed to the lower part of the food waste that is difficult to reach. While transferring, it is heated and dried at the top and bottom at the same time. Therefore, all of these operations, such as to quickly increase the internal drying temperature while reducing the loss of internal heat energy from the initial operation of the food waste dryer 100, are unnecessary for the preheating power waste and drying operation of the food waste dryer 100. It is natural to reduce the waste of power used and reduce the loss of unnecessarily discharging a lot of heat energy to the outside of the food waste dryer 100, and accordingly, the drying time is considerably shortened, so the overall drying efficiency of the food waste is increased. . Furthermore, the upper and lower control barrier plates 20 and 20a have an effect of blocking access to pests, etc. when the food waste dryer 100 is not operated. In addition, a mesh compartment opening and exiting opening 31 disposed in frontal communication with the outer surface of the lower portion of the cylindrical body 11 is shown, which is a process in which the mesh compartment 25 filters wastewater contained in food waste. Due to the occurrence of clogging of the ventilation hole of the mesh compartment 25 by drying in a state where debris, foreign matters, etc. are trapped, the discharge of sewage to the mesh compartment 25 and the ventilation function of the lower circulation of hot air may be significantly deteriorated. Therefore, in order to be able to frequently remove and clean the debris trapped in the mesh compartment 25 from time to time, the mesh compartment 25 is easily attached and detached, and a guard rail for smooth entry and exit of the mesh compartment 25 City) is included.
