Description

Food-wastes processing apparatus

The present invention relates to a food waste treatment apparatus, and in particular, to crush, dehydrate, and dry foods containing a lot of water to simplify the treatment while reducing the cost of treatment, and to recycle the processed food waste as feed or compost. And, because the use of water in the treatment process relates to a food waste treatment apparatus that can be managed cleanly.

As the population growth and the industrial development are highly developed, the food waste that occurs rapidly as the national income increases, the life is improved, the standard of living is improved, and the food is diversified has become a social problem.

These food wastes contain a lot of moisture and easily decay, causing odors to harm the surrounding environment, and in the case of decay, it is impossible to recycle them by feed or compost, resulting in waste of resources and handling due to heavy weight. In order to solve this problem, many food waste treatment apparatuses have been developed in the related art. However, since conventional food waste treatment apparatuses mainly treat by incineration, a lot of smoke is generated, and during this smoke, dioxin is produced. Since harmful gases, such as gas, are generated and harmful to health, and odors are generated during incineration, the treatment device must be installed in a limited place, which is cumbersome for transporting waste, and also takes a lot of time to dispose, resulting in high power consumption. And costly problems to manage The fermentation and heating method of drying method produces a bad smell during treatment and the cumbersome process of culturing microorganisms for fermentation. Residues) and the time required for organic decomposition takes more than 3-4 hours, so the processing time is long, and waste of hard materials such as bones or shells of livestock could not be treated.

The water supply means 8 has both ends communicating with a drain container 33 of the hopper 10 and the dewatering means 5. Inlets 8a connected to each other and water flows in the flow paths The water supply pipe 8b is formed to supply the water supplied from the outside through the inlet 8a to the hopper 10 and the drain container 33 so as to clean the hopper 10 and the drain container 33. And a nozzle 8c installed at both ends of the water supply pipe 8b to inject water into the hopper 10 and the drain container 33. The water supply means 8 is formed by the hopper 10. The waste to be supplied is easily supplied to the crushing means (4), and to wash the drain container 33 and the filter 34, by installing a valve (8d) on both sides of the inlet (8a) to interrupt the flow of water It is preferable to supply water intermittently as needed during the waste disposal process. The food waste treatment apparatus of the present invention is controlled by a control 53 installed in the hopper 10, which is shown in FIG. As described above, it is understood that each function of the circuit breaker 54 and the timer device 55 to prevent a short circuit is performed. It is equipped with a lamp 56, an alarm 57 for notifying a failure or the end of work, a supply lever ON / OFF, a conversion lever 58 for converting a shredding device and a dehydration device, and other necessary functions can be added or subtracted. These functions are controlled by the microcomputer. Next, an example of the use of the food waste processing apparatus of the present invention configured as described above will be described. When power is supplied by the control of the control 53, the main motor 49 and The motor 12 of the waste supply means 3 is driven and the main motor 49 supplies power to each of the power transmission members 50, 51 and 52 connected thereto, so that the dehydration means 5, The shafts of the shredding means 4 and the drying means 6 are rotated, and the power transmission member feeding shaft 11 is rotated. When the treatment apparatus is driven as described above, food waste is supplied to the hopper 10. The garbage thus supplied is fed downward by the rotation of the feeding shaft 11 and supplied to the housing of the shredding means 4. Accordingly, the crushing shaft 19 rotated by the driving means 7 rotates at a high speed to finely crush the garbage flowing between the cutter 18 and the receiving groove 25. In such a crushing process, foreign matters such as chopsticks spoons may be introduced into the garbage, but in this case, the control 53 is rotated to rotate the main motor 49 in the reverse direction to open the foreign material removal window 24 formed in the housing, and the foreign matters. After the crushing process, the waste is dropped and supplied to the housing of the dewatering means 5, and the conveyor shaft 31 of the dewatering means 5 transfers the supplied waste to the outlet 28. At this time, since the outlet 28 of the housing 29 is closed by the outlet pressurizing device 32, the conveyed waste becomes compressed and the contained water is discharged, and the discharged water is filtered out of the filter 34. After being drained to the outside through the drain container (33). When the compressive force overcomes the elasticity of the elastic member 40 of the outlet pressurizing device 32, the door 39 rotates to open the outlet 28 and supplies the hopper 10 of the drying means 6 through the outlet. do. At this time, since the discharge protrusion 31a of the conveyor shaft 31 rotates at the outlet 28 of the dewatering means 5 through which the waste is discharged, the waste is smoothly supplied to the drying means 6. As described above, the dewatering process When the finished waste is supplied to the drying means 6, the drying means 6 transfers the waste to which the rotating conveyor shaft 45 is supplied to the outlet 44 and discharges the waste to the outside. Since the housing maintains a high temperature state by heating the heater 46, the moisture contained in the conveyed waste evaporates. In the above food processing process, the hopper 10 is provided even though the feeding shaft 11 is provided. When the waste is not smoothly supplied or the surroundings of the drain container 33 become dirty with the drain water, the waste water supply unit 8 may be used to smoothly supply the waste and the waste container 33 may be cleaned. Same process as above Beating the food waste treatment are finely shredded by the shredding means 4, and a lot of water removed from the dewatering means (5), since since moisture is evaporated in the drying means (6) is dry.

The food waste treatment apparatus of the present invention configured as described above can be automatically processed when the waste is continuously supplied to the hopper 10, so that the processing time is short and a large amount can be continuously processed. As the food waste is shredded and dried at the same time, the shape and size of the cutter can be adjusted to handle various wastes such as cattle bones, shells or fruit seeds.

In addition, because water is used in the treatment process, not only can the treatment apparatus be cleanly managed, but also the waste to be processed is food containing a lot of salt, so that the amount of salt can be removed by adjusting the amount of waste to be recycled as feed or fertilizer. It does not generate soot or odor, so it has the advantage of protecting health and the environment and being not restricted by the installation site.
