The examples are for a clear understanding of the present invention and the present invention is not limited thereto.

FIG. 1 shows an embodiment of a food garbage disposal apparatus according to the present invention.

Referring to FIG. 1, the food waste disposal apparatus 10 includes an inlet 11 through which food waste is introduced; A first crusher (12) installed below the inlet (11) for crushing food waste by a pair of opposing crushing blades (121); A second crusher 13 installed at the bottom of the first crusher 12 and having a discharge hole 131 capable of crushing and discharging the crushed food waste to a predetermined size; Conveying means (14) provided below the second crusher (13) for discharging moisture while conveying the crushed food waste to a predetermined size; A first drying device (15) for drying the food waste discharged by the conveying means (14); A second drying device (16) for drying the pulverized food waste conveyed from the first drying device (15) while conveying the slurry through the inclined moving blade (161); A discharge device 17 disposed below the second drying device 16; And a driving device M for the operation of the first and second pulverizers 12 and 13. The driving device M operates when a predetermined range of pressure is applied to the first pulverizer 12 It stops.

The processing apparatus 10 can be installed in a place where a certain amount or more of food waste is discharged such as a restaurant such as a restaurant handling food or a collective garbage processing place in a multi-family house, . The processing apparatus 10 according to the present invention is not particularly limited to an installation site, and a plurality of processing apparatuses 10 may be installed in one place as required.

The input port 11 may include a stopper 112 for limiting the range in which the opening and closing door 111 and the opening and closing door 111 are rotated downward. The opening and closing door 111 is formed in a two-plate shape and each one of the edges thereof can be opened and closed in a hinged manner. Specifically, the opening and closing door 111 may have a structure that is opened by the weight of the food and is restored by an elastic means such as a spring. The opening and closing door 111 may have any shape known in the art, and the present invention is not limited thereto.

The stopper 112 may have a function of preventing the foodstuff from flowing down the opening and closing door 111 so that the odor of the lower portion does not rise upward. The degree to which the opening and closing door 111 is opened by the stopper 112 can be limited.

The food waste introduced along the direction indicated by the arrow A through the inlet 11 can be first crushed in the first crusher 12. The first crusher 12 includes a rotating shaft 122 installed below the loading port 11 and rotated by a driving device M such as a motor and a crushing blade 121 formed along the rotating shaft 122 can do. The driving device M may be a motor and the driving force of the driving device M may be transmitted to the rotating shaft 122 by a power transmitting means 123 such as a gear or a belt.

The crushing blade 121 arranged along the rotation axis 122 may be in a separated form. The separate form means that each of the crushing blades 121 is installed independently of the rotating shaft 122 and one end portion is not connected to the other end portion. To make the crushing blade 121 into a separated form, the food waste initially put through the inlet 11 may include such as a lump, for example, such as a wooden chopstick or a metal cutlery. Each of the separate-type crushing blades 121 may be made of a material having a high strength while being formed to have a constant thickness. In addition, each crushing blade 121 may be formed with slanting or other types of crushing projections or grooves. In this way, the separate-type crushing blade 121 having the constant strength is made so that the foreign matter contained in the lump-shaped food waste or the solid food waste can be crushed.

On the other hand, the first crusher may have a structure in which the pair of crushing blades 121 are engaged with each other or alternately arranged to rotate. Specifically, the pair of rotation shafts 122 are disposed in parallel to each other, and the crushing blades 121 are engaged with each other on the rotation shafts 122 or alternately arranged so as to be crushed.

If a foreign matter which can not be crushed by the first crusher 12 designed to have a predetermined strength is injected and thereby excessive pressure is applied to the first crusher 12, the first crusher 12 can be stopped have. In other words, if the first crusher 12 is subjected to a pressure exceeding a predetermined range, the operation of the drive device M can be stopped. To this end, a torque limiter may be installed in the drive M. For example, when a large load or torque is applied to the first crusher 11, the release switch for blocking the connection of the ring is moved by the elastic action to cut off the power supply and stop the operation of the driving device M. For example, the rotating shaft 122 may be rotated in the reverse direction by a driving device M such as a motor capable of reversely rotating, or manually. On the other hand, one end of the first crusher 12 can be made in a detachable form for the removal of foreign matter.

Various structures for stopping the operation of the drive device M or enabling the reverse rotation of the drive device M when the load or torque outside the certain range is caught by the first crusher 12 are the same (10) and the present invention is not limited to the embodiments shown.

The food waste which has been primarily crushed by the first crusher 12 can be delivered to the second crusher 13. The second crusher 13 may function to move the crushed food garbage in the first crusher 12 to a sufficiently small size while moving it downward.

As shown in FIG. 1, the second crusher 13 may include a crushing blade formed to correspond to the outer diameter of the crushing blade 121 of the first crusher 12, and a transfer hole 131. The food located above the second crusher 13 is crushed again by the rotation of the first crushing blade 121 and can be moved downward through the feed hole 131 when crushed to a predetermined size. The transfer hole 131 may have a proper diameter in consideration of the type of food or the degree of grinding. The second grinder 13 may be rotated as necessary, or a grinding blade may be provided just above the transfer hole 131 so that grinding can be performed. In addition, an induction guide 132 for guiding the food waste in a predetermined direction may be provided below the transfer hole 131. The induction guide 132 may have a function of preventing the food waste from leaking into the gap of the processing apparatus 10, for example.

The food waste is crushed by the second crusher 13 to a size smaller than a predetermined size or to be able to pass through the feed hole 131 and the crushed food waste is conveyed to the conveying means 14 along the direction indicated by the arrow B . The conveying means 14 may comprise a conveying passage 141 formed on the rotary shaft 142 and the rotary shaft 142 and may include a coupling device 143 for transmitting the power of the driving device M. [ The conveying means 14 can be operated through the connecting device 143 by the operation of the driving device M. [ Alternatively, the conveying means 14 can be operated by a separate driving device. The conveying means 14 may be, for example, a device such as a rotary screw, but is not limited thereto. In the process of being conveyed by the conveying means 14, pressure is applied to the food garbage, whereby the moisture can be separated. Can be discharged through the water discharge hole 152 through an appropriate path formed in the transfer means 14 and sent to the sewage pipe or collected in a separate storage tank.

The pulverized food waste, which is compressed and primarily discharged as moisture, can be delivered to the compression device 151. The compression device 151 may be, for example, a compression device such that the food may be squeezed and the water may be secondarily separated and discharged into the water discharge hole 152. A filter may be provided above the water discharge hole 152 as needed. The filter can be cartridge-type and can be installed in a replaceable structure. The secondarily removed moisture can be treated in the same or similar way as the primarily separated water.

The pulverized food waste whose moisture has been removed from the compressing device 151 at the second time can be transferred to the first drying device 15 through the discharge passage 153.

The first drying device 15 is, for example, a device for making a lump of food waste in the form of a lump by compression using a stirring device or the like, a function of drying the food by introducing heat, And an outlet for discharging the generated heat to the outside. The first drying apparatus 15 may have a function of drying food by using waste heat, and supplying a certain amount of food waste to the second drying apparatus 16.

The first drying apparatus 15 can supply a predetermined amount of primary dried food waste to the second drying apparatus 16 through the transfer passage 155. When a certain amount of food waste is supplied to the second drying device 16, the transfer passage 155 can be closed. Thus, the first drying device 15 may have a function of a storage device for food waste.

The second drying device 16 corresponds to a device that dries the food waste primarily dried through the transfer passage 155 from the first drying device 15 while moving the same. The second drying device 16 supplies hot air for drying the food waste moving along the moving blade 161 and the moving blade 161 for moving and drying the food while rotating along the rotating shaft 162 A hot air device 163 may be included. In addition, the second drying device 16 may include a temperature sensor for determining whether the hot air device 163 is operating.

When the food waste supplied through the discharge passage 153 is supplied to the moving blade 161, the rotating shaft 162 rotates at a sufficiently slow speed and the moving blade 161 rotates accordingly. The moving blade 161 may be arranged such that a plurality of the moving blades 161 are inclined in a plate shape. By forming the moving blade 161 so as to be inclined, the food waste falls downward along the feeding path due to gravity. The moving speed of the food waste can be adjusted by adjusting the inclination of the conveying path. The transfer path may be, for example, a half-tubular shape or a plate-like shape with a curved edge. If the housing in which the moving blade 161 is housed is cylindrical or rectangular, one moving blade 161 is formed to extend from one end to the other and the other moving blade 161 extends from one end to the other . In this manner, the second drying apparatus 16 can be composed of a plurality of moving blades 161, and each moving blade can have an inclined shape. On the other hand, the movable blade 161 is rotated by the rotary shaft 162, so that the food waste located in the upper moving blade 161 falls downward in the oblique direction by the moving blade 161 located below.

The hot air device 163 for drying the food waste conveyed from the moving blade 161 may be composed of, for example, a fan and a heater. When the internal temperature is raised by the hot air dryer 163, the food waste moving along the moving blade 161 can be dried secondarily. When the internal temperature of the second drying device 16 is raised to a certain level, the operation of the hot air device 163 can be stopped and the waste heat can be supplied to the first drying device 15. On the other hand, if the internal temperature of the drying device 16 falls to a certain level, the hot air device 163 can be operated again. In this way, a temperature sensor may be installed inside the second drying device 16 to determine the operating conditions of the hot air device 163 according to the internal temperature. A condition control device for adjusting the conditions inside the second drying device 16 may be provided and for example a dehumidifier or a pressure control valve may be installed in the second drying device 16. [

The food waste finally dried in the second drying apparatus 16 can be collected in the storage device 17 through the discharge passage 164. And the garbage collected in the storage device 17 may be transferred to another suitable food garbage collection means. Alternatively, the storage device 17 itself can be, for example, a food waste collection container, and the storage device 17 can be made detachable from the processing device 10. [

Referring to FIG. 1, a cleaning and control device for operation of the processing apparatus 10 according to the present invention may be installed. The cleaning and control device may include, for example, a cold water and hot water control device 18. The cold water and hot water control device 18 will be described below again. The cleaning and controlling device may also include such as an operating switch, a temperature setting means of the drying device, a rotating means of the driving device, or means for controlling the opening and closing of the control door. The treatment apparatus 10 according to the present invention needs to be cleaned to remove odors or internal dirt when the treatment of food waste is completed. The cleaning and control device can wash such as the first crusher 12 and the second crusher 13. Alternatively, the water for washing may be tap water. The washing may be performed by injecting water into the inlet 11.

The treatment apparatus 10 according to the present invention can be installed in the base B and the base B can have a moving means R such as a wheel or a fixed leg L for fixing in a fixed position. Various moving means R and fixed legs L can be applied to the processing apparatus 10 according to the present invention.
