The present invention relates to a facility capable of effectively removing the odor and sewage generated from the moisture removal by the dryer and the food waste by the main operation of compression by the compression cylinder and grinding by a pulverizer / mixer or cutting edge. Composting facilities using existing enzymes have the following disadvantages, which is not the ultimate food waste treatment method. First, expensive equipment that requires a budget of several hundred billion won is required. Secondly, a large number of operating personnel are needed, mainly technical workers. Third, in order to process hundreds of tons of food waste per day, at least 10,000 pyeong of land is required, which requires a large treatment facility. Fourth, conventional composting facilities using enzymes require at least a full processing time. Fifth, a large number of personnel are required because foreign matters other than food must be separated / removed. Sixth, food waste obtained through composting facilities in the domestic food culture is not suitable for composting because it contains high concentrations of salt. Finally, a large amount of sawdust is required in the composting process, which increases the volume after treatment, making it difficult to prepare a large place for loading. In addition, the facility itself is not sealed, and when using a composting device using enzymes due to the moisture contained in the food, there is a high possibility of complaints due to the generation of odors and bugs, so it is very difficult to put to practical use.

In contrast, when using the food waste treatment facility by the compression / grinding and drying method according to the present invention, it has the following advantages over the conventional composting facility using the enzyme. First, it can be installed at a relatively low budget compared to the existing composting facilities using enzymes. Second, while existing composting facilities using enzymes are mainly managed by a large number of skilled workers, only three or four small operating personnel are needed, and because it is a fully automated facility, management is more efficient and surveillance cameras are placed in the right place. All the situation of the facility can be controlled from the central control room for convenience in maintenance and repair. The third treatment facility can be installed on a site of about 1,000 pyeong, and there is no need to separate / remove foreign substances other than food, thus eliminating the need for additional personnel. In addition, odors and sewage generated during the treatment of food waste are continuously collected during treatment, purified through wastewater treatment facilities and sanitation, and discharged to the outside of treatment facilities, thereby eliminating the possibility of complaints.

Hereinafter, the operation and step-by-step processing characteristics of the food waste treatment facility according to the present invention will be described briefly.

Food waste treatment facility according to the present invention is a feature that is not affected by the food culture of people while maintaining the existing collection system. This facility loads food waste into the transport tank by the transport truck and puts it into the hopper. The input food waste mass is first crushed by a crushing blade and removes water accumulated in a plastic bag or a pile of trash. Garbage moved to the part with multi-stage cutting edge by conveyor is secondary grinding and water removal and compressed to remove water. The vertical and horizontal compression is performed sequentially to extract most of the water contained between the food wastes. The extracted water passes through the air purifier or the wastewater treatment device through the odor / water suction device, It is designed to be converted to water and discharged out of the treatment plant.

And most of the dehydrated food waste is broken down into completely small granules through a grinder and mixer several times. The very small grains of the broken food waste are delayed by passing through the stagnation and drying chambers, causing the moisture contained in the small grains to come to the surface and then removed by heating and repeatedly removing water. Even the small amount of water left in the stomach can be removed. Most of the water-removed small particles of food waste are made into a convenient form for transporting again or a certain form to facilitate the post-treatment process.

The food waste treatment facility by the compression / crushing and drying method according to the present invention is completely sealed in order to reduce the possibility of complaints such as odors and is equipped with a fully automated facility, so that all situations related to the facility are controlled in the central control room. It is designed to be possible.

Hereinafter, the food waste treatment method using the facility according to the present invention will be described with reference to the accompanying drawings.

1 is a conceptual diagram of the input of the food waste and the primary crushing unit of the equipment according to the present invention (1) is a food transport tank, (3) left and right transporter, (6) left and right transporter frame, (7) hopper, (8) is the primary conveyor, (11) the cutting edge, (13) the grinding blade, (15) the odor / water suction device, (16) the input / crusher catch basin, (17) the secondary conveyor, 20 is a vertical compression cylinder.

The food waste transferred from the food waste collection truck to the transport tank 1 is transported by the elevator 2 to the place where the left and right transport apparatus 30 is located, and the left and right transporters 3 lift the transport tank 1 directly from the hopper 7. The transport tank transporter, which is transported from the food waste truck to the left and right transporters 3 via the elevator 2, can be selectively used according to the installation area, so that the space can be installed vertically when the space is narrow. Otherwise, the equipment itself is installed horizontally, eliminating the need for the elevator 2. The food waste mass or bags put into the hopper 7 are first cut by the grinding blade 13, rather than being cut into small portions. This is to remove the liquid components remaining in the food waste, that is, the grinding blades 13 cross each other to remove the water accumulated in the food waste bag. Using the blade, the bag or lump is scratched to remove the liquid and the garbage bag is cut at regular intervals.In this way, the waste is removed and the crushed food waste is cut by the primary conveyor (8). 11. The food waste passing through the cutting edge 11 is discharged back to the input / crusher catch port 16, and at the same time, the food waste is secondly crushed by the cutting edge 11 and the secondary conveyor ( 17) All these processes are designed to be monitored in the central control room 75 by installing a closed circuit camera.

The secondary conveyor 17 moves the secondary crushed food waste and sends it to the portion where the upper and lower compression cylinders 20 are located. The food waste sent here is continuously arranged to release a large amount of water contained in the food waste itself by the compression cylinders 20 and 21 (see FIGS. 2 and 5).

2 is a conceptual diagram of the compression and crushing unit of the installation according to the present invention. (20) is the up and down compression cylinder, (21) is the left and right compression cylinder, (22) is the up and down compression cylinder, (23) the compression / crushing part collecting device, (26) the lower feed guide tube, and (27) the compression / The grinder catcher, 29 is a left grinder, 30 is a right grinder, and 32 is a compression / crusher mixer. When the food waste, which has passed through the cutting edge 11 and the secondary conveyor 17, passes through the right inlet of the upper and lower compression cylinders 20 and collects in the passage part where the upper and lower compression cylinders 20 move, a predetermined amount is collected into the control circuit. The signal is transmitted and the up and down compression cylinder 20 starts to move down to compress the food waste. The compressed food waste is again compressed by the left and right compression cylinder 21 to the left of the compression / crushing portion collecting device 23 to remove most of the water contained in the food waste. The water generated by the compression is guided by the transport guide tube 26 at the bottom of the collecting plate through the compression / crushing unit collecting device 23 to be collected at the compression / crushing unit collecting port 27, and the dirty water discharged through the collecting unit is discharged to the wastewater. Sent to the treatment plant. In addition, all wastewater from the food waste treatment facility by compression / crushing and drying method was sent to the wastewater treatment plant to be reduced to clean water.

Since the food waste compressed to the left by the left and right compression cylinder 21 is in a compressed state, it is agglomerated, and thus breaks up the food waste agglomerated in the downward direction with the grinders 29 and 30 by the up and down conveying cylinder 22 of the crushing unit. Boosted. The food waste thus pushed through the left grinder 29 and the right grinder 30 is subjected to the third grinding, and is further broken while being mixed by the compression / crushing mixer 32. At this time, the thing to note is that the food waste is designed to stagnate by varying the rotational speed of the grinder (29,30).

3 is a conceptual diagram of the primary drying unit by the hot air of the equipment according to the present invention. Reference numeral 34 denotes a dryer hot air, 37 a conveyor belt, 41 an intermediate turnover, 45 a final turnover, and 48 a dryer mixer. Most of the water contained in the food waste was removed by the left and right compression cylinders 21, but since a small amount of water is contained in each of the waste grains, a stagnation / secondary drying unit is also installed in the next step if the process is to remove it. It was designed to remove all remaining small amount of water continuously. This is a process for removing the moisture accumulated on the surface of the waste grains by applying hot air to the dryer hot air blower (34). The food waste mixed and crushed through the compression / crusher mixer 32 passes through the conveyor belt 37, and removes moisture by using hot air from the dryer hot air blower 34. The inside and the outside of the food waste is turned over so that the transported waste can be evenly removed moisture. Then, after the surface moisture is removed by hot air, it is crushed into small grains again by the dryer mixer 48. In this process, all the granules which were not broken during the previous grinding process are also reliably cut.

4 is a conceptual diagram of the stagnation secondary drying unit of the installation according to the present invention. (50) is the top feed screw, (51) the top stirrer, (54) the stag / dryer mixer, (59) the bottom feed screw, (62) the bottom feed guide plate, and (69) the transfer workpiece heating. It is wealth. The moisture is removed by the cylinders 20 and 21 and the drying unit hot air blower 34, but it cannot be said that all the moisture contained in the grains of food waste has escaped. Therefore, the process of transporting food waste grains broken into small particles is carried out with time delay, and the transfer processing heating part 54 is placed in this section to apply heat to remove the moisture contained in the grains to the surface. have.

The food waste grains flowing into the upper right side of the upper feed screw 50 are transferred at a slow speed. During the transfer, the food waste particles are repeatedly installed to apply heat and blow dry air to cool the heat. It is designed to completely remove the moisture of food waste by repeatedly adding. In addition, the water treatment process is made in multiple stages, and is designed to be selectively processed according to the type or amount of food waste to be treated. This figure illustrates an example of removing water using a feed screw composed of two stages as one example. After the food waste passes through the upper feed screw 50, the food waste is mixed well while passing through the stagnation / drying part mixer 54 and continues to be conveyed by the lower feed screw 59. Transfer material heating part 69 is repeatedly installed even during the movement of the lower part to continuously carry out water removal activities as in the upper part, and the feed material heating part 69 at the lower part is installed in a smaller number than the upper part to remove food waste. When the temperature goes out through the lower transfer guide plate 62. And the food waste conveyed along the lower transfer guide plate 62 is made in a convenient form for transporting while passing through the presser 74, which is the last process, to be moved to another place using the treatment carrier 64 or the treatment carrier. do. (See also Figure 21)

5 is the food waste collection and input preparation unit, (1) the food transport tank, (2) the elevator, (3) the left and right transporter, (4) the left and right transporter motor, (5) the lifter, (6) is the left and right carrier frame. When the vehicle carrying the toweled food waste is waiting at the entrance of the treatment plant, the food waste is transferred to the food conveying tank 1 by the situation instruction of the control room. Food waste transported in the food transport tank 1 is transported to the upper part of the treatment plant by an elevator 2 operated by the lifter 5, and the transported food transport tank 1 is caught by the left and right transporters 3. . The left and right transporters 3 serve to move the food transport tank 1 to the inlet of the hopper 7 while the left and right transporter motor 4 is operated to move left and right along the left and right transporter frame 6. The food transport tank 1 moved to the inlet of the hopper 7 is to wait until the instruction to insert. One of the characteristics of the present invention is that it can be used even if foreign matter is added to the food compared to the conventional composting equipment using the enzyme. This has a significant meaning, meaning that the food waste that is put in the bag at home or in a restaurant can be disposed together with the bag. Therefore, there is an advantage that the existing method can process the entire collection bag and food as it is compared to generate another garbage called the collection bag. (See Figure 3)

6 is a detailed view of the food waste input preparation unit. (1) the food transport tank, (3) the left and right transporter, (4) the left and right transporter motor, (5) the lifter, (6) the left and right transporter frame, (76) the left and right transporter hanger, (77 ) Is the transfer hook. The transport hanger 77 of the food transport tank 1 carried by the lifter 5 to the upper part of the processing plant is connected to the left and right transport hangers 76 of the left and right transporters 3 and is operated by the left and right transport motors 4. It is conveyed to the inlet of the hopper 7 along the left and right transport frame 6. (See Figure 3)

7 is the input and crushing portion of food waste. 6 is a left and right transport frame, 7 is a hopper, 12 is a grinding motor, 13 is a grinding blade, and 19 is a hopper surveillance camera. Food waste transported by the jaw transporter 3 along the left and right transporter frame 6 is introduced into the hopper 7. The inside of the hopper is sent to the control room by the hopper monitoring camera 19, and the input speed and the input amount of food waste from the control room are adjusted. The injected food waste is primarily pulverized by the grinding blade 13 driven by the rotation of the grinding motor 12. Since the food waste is located inside the bag by the collection bag, it is first necessary to dismantle the collection bag. When the bag is ruptured by the crushing blade, the food waste inside is taken out of the bag together with the sewage, and the food waste is crushed. The food waste which is thrown into the hopper and crushed is transferred to the next treatment process, the conveying and grinding process.

8 is a conveying and crushing part of food waste. (8) is primary conveyor, (9) transfer motor, (10) pulley, (11) cutting edge, (14) cutting edge surveillance camera, (15) odor / moisture suction device, (16 ) Is an input / crusher catchment port, 17 is a secondary conveyor, and 18 is an idle roller. The conveying and crushing unit is fed through the hopper 7 and driven by the conveying motor 9 and the pulley 10 so that the food waste crushed by the crushing blade 13 is compressed by the compression cylinder 8. ) And the secondary conveyor 17 is the portion to be transferred. The food waste is pulverized more finely by the cutting edges 11 arranged in multiple stages while the food waste is transported, and the sewage with the food is conveyed to the wastewater treatment plant through the input / crushing part catch port 16. Then, the odor and the moisture intake device 15 is purged through the purifier odor and moisture contained in the air is discharged to the outside. Each conveyor maintains the tension of the conveyor by the idle roller 18. (See Figure 3)

9 is a detailed view of the primary conveyor portion for the transport of food waste. (9) is the transfer motor, (10) is the pulley, (8) is the primary conveyor, (18) is the idle roller, and (78) is the roller. Food waste introduced through the hopper 7 is a portion to be conveyed after being crushed by the grinding blade (13). When the feed motor 9 is operated, the primary conveyor is operated by the rotation of the pulley 10 and the roller 78, and the food waste is placed on it and transferred to the receiving and crushing unit (see FIG. 3).

10 is the odor / water removal unit. Denoted at 15 is an odor / water suction device and at 17 is a secondary conveyor. The finer the food waste is, the more the surface is in contact with air, so much of the odor and gas that existed inside are released to the outside. After the second grinding is performed by the cutting edge 11, a large amount of odor and gas generated from the food waste transferred by the secondary conveyor 17 is sanitized by the odor / moisture suction device 15 and then outside the treatment plant. Is released. Through the secondary conveyor 17, the food waste is transferred to the compression unit, which is the next process, to forcibly remove water by using a compression cylinder (see FIG. 3).

11 is a process of adding and grinding food waste. (7) is the hopper, (8) the primary conveyor, (9) the transfer motor, (10) the pulley, (11) the cutting edge, (12) the grinding motor, (13) the grinding blade, (14 ) Cutting edge surveillance camera, (15) odor / moisture suction device (16) input / crusher catch port, (17) secondary conveyor, (18) idle roller, (19) Hopper surveillance camera. The food waste contained in the food transport tank 1 carried by the left and right transporters 3 waits at the inlet of the hopper 7 and receives a control signal and is introduced into the hopper 7. The input is made by the hopper monitoring camera 19, the amount of waste put into the hopper and the input speed, the situation inside the hopper is sent to the central control room and checked by the manager 71. Food waste can be a cause of many complaints because it can cause hygiene and pollution due to the presence of a large amount of gas with a bad odor. Thus, the entire treatment plant is isolated from the outside. Therefore, in order to increase the internal operating situation and processing efficiency of the treatment facility, the entire operation is remotely controlled by using a computer in a control room outside the treatment plant using multiple surveillance cameras. That is, the treatment facility is fully automated to operate at an optimum value according to the amount and type of food waste generated, and when the situation changes, the internal situation sent to the manager 72 through the monitoring camera is manually adjusted. Hopper surveillance camera is one of them. Since the food waste is contained in the collecting bag, it is crushed by the crushing blade 13 driven by the crushing motor 12 after being put into the hopper 7. The bag is passed through the crushing blades rotated around different axes, and the bag is broken by the crushing blade, and the food waste is squeezed while notifying the gap between the crushing blades. At this time, the moisture present between the food waste particles is easily released. Korea's food culture often contains a lot of moisture, so a large amount of moisture inside the bag will be spilled. Therefore, the water that was in the food waste while moving together with the crushed food waste is collected in the wastewater treatment plant through the input / crushing part catch port 16. Food waste is more finely ground by the cutting edge (11). At this time, in order to increase the efficiency of the compression in the next step by using the multi-stage cutting edge (11) to crush the food waste as fine as possible. In addition, various odors and gases from the food are collected separately by the odor / water suction device 15, and the collected odors and gases are deodorized by the deodorizer and discharged to the outside of the treatment plant. Through this process, water and odors containing food waste are firstly removed, and finely pulverized by the grinding blade 13 and the cutting edge 11, and then collected in the next process of compression by a compression cylinder. As described above, the treatment facility according to the present invention continuously collects sewage and odor generated during each treatment process and then completely purifies or discharges it to the outside of the treatment facility after treatment using a dust collecting facility, thereby preventing environmental pollution and generating complaints. Fewer possession of (see Figs. 1 and 23).

12 is a process of compressing food waste. Denoted at 20 is a vertically compressed cylinder, at 21 at the left and right compression cylinders, and at 22 at the crushing unit. When a predetermined amount of food waste transported in the previous step is hydraulically operated up and down compression cylinder 20 is lowered by the control circuit to compress the food waste, and horizontally compressed again by the left and right compression cylinder 21 to the left Will be transferred. The food waste is mainly reduced by the left and right compression cylinder 21. The food waste conveyed to the left is conveyed to the grinder and mixer by the vertical conveying cylinder 22. In this process, the food waste is greatly reduced in volume because most of the moisture contained in the food waste is removed while being compressed by the cylinders.

The compressed food waste is conveyed down through the compression mill collecting device 23, and then crushed by a pulverizer and a mixer driven by a motor. The process of crushing food is monitored in the central control room 75 by the crush monitoring camera 28. The left grinder 29 and the right grinder 30 driven by the grinding / mixing motor 31 have different rotation speeds to prevent food waste from being caught between them. Compressor / crusher mixer 32, driven by mixer motor 33, crushes and shreds the food waste pulverized in the above step again and passes to the next step. (See Figure 9 of Iron.)

When the food waste conveyed to the compression and crushing unit is accumulated by a control circuit, the food waste is first compressed by the upper and lower compression cylinders 20 and then transported downward, and the transported food waste is moved to the right again by the left and right compression cylinders 21. Water is removed and the volume is reduced. Moisture generated by the compression cylinders is collected through the compression / crushing part collecting device 23 through the conveying guide pipe 26 to the compression / crushing collecting hole 27. The food waste aggregated by the compression of the cylinder is then passed through the grinding and mixer, and the food waste is crushed by the left grinder 29 and the right grinder 30, and crushed by the compression / pulverizer 32 Food waste is mixed.

The food waste conveyed by the conveyor belt 37 is twisted by the intermediate turnover 41 driven by the intermediate turnover motor 42 and dried to the moisture in the inside. This process is monitored in the central control room 75 by an intermediate turnover surveillance camera 40 attached to the dryer separator 39. The odor / moisture suction device 43 installed in the transfer passage absorbs the odor that may occur when the garbage is dried and passes through the liquid to remove it. At the end of the transport passage, the food waste is mixed once by the final turnover 45 driven by the final turnover motor 46, which is also in the central control room 75 by the final turnover surveillance camera 44. Is monitored. The food waste past the final turnover 45 is mixed again by the dryer mixer 48 and then transferred to the next step. This process is also monitored in the central control room 75 by the mixer surveillance camera 47. The conveyor belt 37 is provided on the upper plate of the conveyor support 35 supported by the conveyor support beam 36.

The upper shaft power generating motor 49 rotates the upper feed screw 50. The dried food waste, which is smallly cut while being compressed / crushed by the upper feed screw 50, is partially dried while passing through the conveyed material heating unit 69, and odors and moisture generated during the drying of the food waste are top odors. / The water suction device 53 absorbs. After this process, the food waste is moved to a dry wind to cool the applied heat. This dehydration process by heating and dry wind is repeated in several steps in the upper feed screw 50 and the lower feed screw 59. (See Figs. 5, 7 and 8)

After the first stagnation / drying process, which is one of the multi-stage heating and dry air removal processes, food waste is removed to some degree of odor and water, and most of the food waste from which odor and water is removed is transferred to the upper screw. By 50 to the stagnation / dryer mixer 54. Food waste sent to the stagnation / dried mixer 54 is mixed evenly in this process to facilitate passage of the second stagnation / drying chamber, and the first stagnation / driving by the lower feed screw 59 for complete odor and water removal. Pass through the second stagnation / drying chamber which has the same structure as the drying chamber. In this process, the monitoring camera 52 is attached to the circumference | surroundings in order to monitor the operation | movement state of the stagnation / drying part mixer 54.

Food waste that has passed through the first and second stagnation / drying chambers removes even the moisture contained in the food by multiple stages of heating and dry wind. In this way, most of the food waste from which moisture is removed is received in the outlet guide hopper 63 by the guide of the lower transfer guide plate 62 attached to the lower transfer screw 59. Food waste contained in the outlet guide hopper 63 is compressed into a very small volume while passing through the presser 70. In this process, the food waste is made into a size that can be transported and processed, and is sent to the processed material transporting device 64. Food waste sent to the treatment conveying device 64 is moved to another place for post-treatment.

The food waste, which is cut into pieces through compression / crushing, enters this passage to remove moisture for the third time after drying by hot air. In this process, the part to heat food waste and the part to cool and dry heat by dry wind are repeated many times. In addition, the food waste, which is crushed finely, is repeatedly mixed through several upper stirrers 51 and lower stirrers 60 while the temperature rises and falls repeatedly, and this process is included in the food wastes through a multi-step process that is repeated several times. It also removes the moisture.

This figure describes the process of stagnation / drying in two stages, and when the actual system is manufactured, it can be configured in several stages depending on the type and amount of food. After the multi-step water removal process, the food waste goes through the first stagnation / drying process of the upper layer, and then mixes the food wastes by the stagnation / drying part mixer (54), and then passes through the second stagnation / drying chamber of the lower layer. Remove most of the moisture. In this process, the heating part and the cooling air through the dry wind, and the part to dry the moisture that has leaked to the surface is installed, most of the water is removed food waste is guided by the discharge guide plate (62) of the outlet guide hopper (63) It will be contained in. Food waste contained in the discharge guide hopper 63 is made in the size of a size that can be transported and processed through the presser 70, and then moved to another place for post-treatment after being sent to the processing material transport device 64. (See Figure 8)

In addition, the monitoring monitor 73 is designed to be able to check the dust collector or even the water removal device is designed to manage even the peripheral device of the food treatment device. The manager 72 records all these monitoring conditions and records on a weekly and monthly basis, and presents the problems of the food processing process so that the convenience of work and the replacement of workers can be solved. (See Figs. 5 and 7)

24 is a conceptual diagram showing the water removal process of the food waste particles. As food waste passes through the food waste processing facility, it can be divided into the following subsections. Firstly, the water between the particles of the food waste is forcibly removed by the compression force of the compression cylinder until the food is finely crushed inside the collection bag. The second process is to remove the moisture on the surface of food waste particles by the dryer. The third step is to finally remove the water present inside the food waste by heating. Through this process, the water contained in the food waste is almost removed (see FIGS. 25 and 26).

25 is a conceptual diagram showing the water content in each step in the water removal of food waste over time. The first section is where food waste is removed by the compression cylinder, where a significant amount of moisture in the food waste is removed. Moisture on the surface and inside of food is also removed, but mainly between food particles. In the second zone, water is removed by hot air conditions, and water on the surface of food waste is removed. Finally, it is the area where moisture inside food is dried by hot wire. Looking at the time taken for each step, the time taken for the removal by the compressive force, which is the first zone, is the shortest and the amount that is removed the most. The amount removed in the last zone is relatively small and the time required is relatively long. The division of the zones in this figure is based on the classification in FIG. 24 (see FIGS. 24 and 26).

26 is a conceptual diagram schematically showing each step of the food processing facility. Referring to the moisture of the food waste removed at each step as follows. The food waste collected by the collection vehicle is loaded in the food transport tank and waits at the inlet of the hopper 7 by the left and right transporters. In this process, a large amount of moisture is contained between the food waste particles and the surface particles. The food waste waiting at the inlet of the hopper 7 is firstly crushed by the crusher 13 and is conveyed between the processes by the conveyors 8 and 17 and placed in multiple stages before being transferred to the compression cylinders 20 and 21. By the cutting edge 11 is finely pulverized second. While crushed finely, the water located between the collection bags is leaked out and collected in the sump 16.

When food waste is conveyed to the compression cylinders 20 and 21 through the conveyors 8 and 17, water is forcibly removed by the high compression force of the compression cylinders. At this time, a considerable amount of moisture present between food waste particles is forcibly removed. After the compression is finished, the powder is more densely crushed by the grinders 20 and 30 and drying by the hot air 34 is started. In this process, the moisture on the surface of the food waste is removed, and is dried by the hot wire 69 while being transferred through the transfer screw and the stirrer. At this time, the water is almost dried up to the moisture existing in the food waste. The food waste thus treated is compressed / reduced by a compressed container to minimize its volume (see FIGS. 24 and 25).

When the food waste transported by the collection vehicle is located at the entrance of the treatment facility, the food transport tank 1 is transported by the lifter 5 to the upper portion of the treatment facility. The food transport tank 1 transported to the upper side waits at the inlet of the hopper 7 along the left and right transporter frame 6 by the left and right transporter, and feeds the food waste into the hopper 7 in response to a control signal. The injected food waste is pulverized and conveyed by the primary conveyor and finely crushed by the cutting edges 11 arranged in multiple stages. The crushed food waste is transported by the secondary conveyor and then compressed by the upper and lower compression cylinders 20 and the left and right compression cylinders 21. At this time, most of the moisture between the food waste particles is removed and some of the moisture that is located in the food particles is also removed. Removed. Compressed food waste is pulverized and mixed by a pulverizer / mixer driven by a pulverization / mixing motor 31, and a large amount of water discharged from the waste during compression is compressed / pulverized through the compression / crusher catcher 27. It is collected by a collecting device and purified from the wastewater treatment plant and discharged outside the treatment facility. The crushed / mixed food waste is dried by the dryer hot air blower 34, and is transported on the conveyor belt 37 to be mixed by an intermediate turnover 41 device over multiple stages to increase drying efficiency. This removes a considerable amount of water on the surface of the food waste, is mixed and pulverized again through the drying unit mixer 48 is conveyed by the upper feed screw 50 of the stagnation / secondary drying chamber is finally dried.

In this process, the heating unit by heating wire and the cooling unit by natural drying are repeatedly dried to moisture present in the food waste particles. Odor and moisture are removed by the upper odor / moisture inhalation device 53 in the middle of the conveyance screw is transported cleanly through a brower is discharged to the outside of the treatment facility. Since the time to remove water in the inside of food waste is relatively long, it is made over the top and the bottom and is fixed to the structure by the upper shaft support 55, and this process has a relatively long time, so the loading capacity is This is necessary given the big things. The dried food waste conveyed through the lower conveying screw (59) is introduced into the outlet guide hopper (63) via the lower conveying guide plate (62) and processed after being processed in a good state to be conveyed by the processing material conveying device (64). do. The lower feed screw portion is also supported by the lower screw support 67. All parts of the treatment plant are automatically controlled by automated equipment in the central control room 75.
