BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food waste disinfection apparatus,

More particularly, the present invention relates to an apparatus and method for disinfection and drying a food waste remover which collects food waste discharged from a home, a restaurant, and a foodservice station, and then easily sterilizes and dries the treated food waste.

Due to the human dietary habit, a large amount of food waste is generated at home, restaurants, and group feeding halls. Food waste is a problem of disposal due to the problem of odor and leachate.

Recently, food waste has been reprocessed and processed to be used as livestock feed or fertilizer.

Conventionally, in order to process the food waste into feed, the collected food waste is firstly pulverized, the foreign material is removed, and then the second pulverization process is performed. Then, the food waste is mixed with a desiccant, sterilized with quicklime, and mixed with a footing agent to be supplied to the farmhouse. The feed of livestock fed in this way is a wet state in a dead state.

Wet livestock feeds are not as clean as they can be seen by the naked eye, they can cause bad odors and cause the livestock to be inedible and, in some cases, cause disease to the livestock.

Further, in order to process food waste into feed, a process of sterilization at a temperature of 100 ° C or more for 30 minutes or more is required. The disinfection process and the drying process are separately performed in different apparatuses in the process of treating food waste, so that it is troublesome to transfer food waste.

The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

FIG. 1 is a perspective view showing an external configuration of a food waste sludge sterilization and drying apparatus 1 according to the present invention, and FIG. 2 shows a process of drying food waste sludge A by a food waste sludge sterilization and drying apparatus 1 Fig. 3 is a cross-sectional view showing a cross-sectional structure taken along line AA in Fig. 1. Fig.

As shown in the drawings, the apparatus for sterilizing and drying food waste sludge according to the present invention comprises a sterilizing drying pot 100 for stirring and drying food waste A, a drum for applying a driving force to rotate the sterilizing drying pot 100, A driving unit 200, and a drum heating unit 300 for applying heat to the sterilizing drying pot 100. The apparatus for sterilizing and drying the food waste sludge according to the present invention can dry the food waste A at a low electric power with a simple structure. The food waste (A) dried in the food waste disinfection and dry processing apparatus (1) of the present invention can be processed into livestock feed through an additional process.

The sterilization drying pot 100 is formed in an elliptical shape in cross section and is disposed at a predetermined angle to the ground surface. The sterilizing drying pot (100) is rotated by the drum driving unit (200). The sterilizing drying pot 100 includes a pot body 110 having a space in which the food waste A is stirred, an opening and closing door 120 provided at the tip of the pot body 110 to be openable and closable, And a heat insulating cover 150 covering the outside of the cooker main body 110. As shown in FIG.

The sterilization drying pot 100 is formed of a metal material having a good heat transfer efficiency. The sterilization drying pot 100 quickly transfers the heat generated from the heat generating part 310 disposed at the lower part to the entire area so that the food waste A contained therein is dried.

The sterilization drying pot 100 is provided in an elliptical shape having a predetermined length. As shown in the drawing, the food inlet / outlet opening 111 is arranged at an angle to the upper side at a predetermined angle.

The opening and closing door 120 is openably and closably provided on the food inlet and outlet 111 side of the sterilizing and drying pot 100. The food waste A is supplied into the sterilizing and drying pot 100 while the opening and closing door 120 is opened and the opening and closing door 120 is closed during sterilization of the food waste A, (120) is opened. When the drying process of the food waste A is completed, the opening / closing door 120 is opened and the food waste A is discharged to the outside.

The stirring vane 130 is integrally joined to the inner wall surface of the cooker main body 110 to stir the food waste A. The stirring wing 130 is formed on the inner wall surface of the cooker main body 110 in a spiral shape along the axial direction. The food waste A may be introduced into the cooker main body 110 or the food waste A may be discharged to the outside of the cooker main body 110 along the rotating direction of the cooker main body 110. [

The stirring blade 130 is coupled to the inner wall surface of the pot body 110 as shown in FIG. 3, so that the central region of the pot body 110 becomes empty. Heat generated in the heat generating part 310 is transferred through the empty space and is contacted with the food waste A to sterilize and dry the food waste A.

The heat insulating cover 150 covers the outside of the cooker main body 110 so that heat generated in the heat generating part 310 is directed to the cooker main body 110 without being discharged to the outside. 2 and 3, the heat insulating cover 150 is spaced apart from the cooker main body 110 by a predetermined distance.

Since the heat generating part 310 is disposed at one side of the lower part of the cooker main body 110, the heat locally stays in a part of the cooker main body 110. The heat insulating cover 150 covers the periphery of the cooker main body 110 so that the heat generated by the heat generating part 310 is not released into the atmosphere but covers the cooker main body 110. The heat H generated in the heat generating part 310 is dispersed by the heat circulating fan 320 and stays in the space between the heat insulating cover 150 and the cooker main body 110, Circulated through the circulation path that is returned to the pot circulating fan 320 and then into the pot body 110.

On the other hand, an ultraviolet sterilizing lamp 117 may be attached to the food inlet / outlet 111 of the cooker main body 110 to sterilize food. At this time, the ultraviolet sterilizing lamp 117 is fixedly coupled to the lower portion of the detachable funnel net 160.

The detachable funnel net 160 is formed in a funnel shape and inserted into the pot body 110 as shown in FIG. At this time, an ultraviolet sterilizing lamp 117 is disposed below the detachable funnel net 160. The detachable funnel net (160) is formed in a mesh net shape to block the food from being discharged outside the pot body (110) when the sterilization process is proceeded with the opening and closing door (120) opened.

The ultraviolet sterilizing lamp 117 irradiates the ultraviolet rays with the food during sterilization and drying of the food to increase the sterilization efficiency of the food.

The drum driving unit 200 causes the sterilization drying pot 100 to rotate so that the food waste A therein is continuously stirred. Since the sterilizing and drying pot 100 is rotated by the drum driving unit 200, the food waste A containing a large amount of moisture is continuously stirred and the heat is uniformly transferred to the entire area and the drying efficiency is improved.

The drum driving unit 200 includes a driving motor 210 for generating a driving force and a driving roller 220 for transmitting the driving force of the driving motor 210 to the pot body 110. The driving roller 220 is rotated in contact with the lower part of the cooker main body 110 to allow the cooker main body 110 to rotate.

In some cases, a driving gear may be used instead of the driving roller 220, and in this case, a coupling gear may be formed along the outer circumference of the cooker main body 110.

A bearing 230 is provided between the cooker main body 110 and the fan receiving pipe 330 to support the cooker main body 110 so that the cooker main body 110 rotates. Accordingly, the pan receiving pipe 330 is fixed in position, and only the pot body 110 can be rotated.

The drum heating unit 300 applies heat to the pot body 110 so that the food waste A contained in the pot body 110 is dried. The drum heating unit 300 includes a heat generating unit 310 generating heat, a heat circulating fan 320 circulating heat, a fan receiving pipe 330 accommodating the heat circulating fan 320, And a heat circulation pipe 340 connecting the fan 150 and the fan receiving pipe 330.

The heat generating unit 310 may be provided as an electric heater such as a heater, or may be provided by directly burning butane gas or methane gas. The heat circulation fan 320 supplies the heat transferred through the heat circulation pipe 340 to the pot body 110 again.

The heat generated in the heat generating part 310 heats the cooker main body 110 itself and is transferred into the cooker main body 110. The heat is moved along the empty space in the center of the cooker main body 110 and comes into contact with the food waste, thereby sterilizing and drying the food waste.

The heat generated in the heat generating unit 310 moves along the heat insulating cover 150 and moves to the thermo-circulating fan 320 through the heat circulating pipe 340 and then to the pot body 110 again.

The maximum heating efficiency can be obtained by the local heating by the structure of the drum heating section 300 and the structure of the heat insulating cover 150.

The device for sterilizing and drying food waste remnants according to the present invention may further include a mixing ball 400 installed inside the pot body 110 to improve the sterilization and drying efficiency of the food waste A contained in the pot body 110, .

4 is an exemplary view showing various forms of the mixing ball 400 of the present invention. The mixing ball 400 may be formed of metal or stone. The mixing ball 400 is disposed on the bottom surface of the pot body 110 due to its heavy weight when the pot body 110 is rotated as shown in FIG. Thereby preventing the food waste A from contacting the pot body 110 directly.

When the garbage A in the gel state is in direct contact with the hot pot body 110, it is burnt or pressed. The mixing ball 400 is disposed on the bottom surface of the pot body 110 to prevent the phenomenon from occurring. In addition, the mixing ball 400 is rotated together with the food waste A so that the foods are mixed with each other and the heat is transferred well.

Meanwhile, the mixing ball 400 may be formed of a ceramic material that emits far-infrared rays when heated. When the pot body 110 is heated and heat is applied to the mixing ball 400, the mixing ball 400 emits far infrared rays to sterilize the surrounding food waste A.

In addition, the mixing ball 400 may be formed of a metal material. The mixing ball 400 is heated to a high temperature from the outside and supplied into the cooker main body 110. The mixing ball 400 is stirred with the food waste A and contacts the food waste A to heat and dry the food waste A .

In some cases, the mixing ball 400 may be provided to generate heat itself. That is, the mixing ball 400 may be provided in such a form that sodium chloride, activated carbon or the like comes into contact with oxygen to generate an exothermic reaction.

4, the mixing balls 400 may be formed in a circular shape or an elliptical shape, or may have a shape in which a hole 410 is penetrated on a surface thereof, or a shape in which sharp-pointed protrusions 420 are provided .

The apparatus for sterilizing and drying a food waste sludge according to the present invention may further comprise a device for directly feeding the food waste A into the pot body 110 according to the moisture contained in the food waste A, It can be put in the state that it is put in.

The juicy food waste (A) is in the form of porridge. When the food garbage A in the gel state is directly injected into the cooker main body 110 and heat is applied at a high temperature, the food waste A is burnt in a state where the metal sticks to the inner wall surface of the cooker main body 110 do. In other words, it is not dried and burned, so it can not be recycled as feed for livestock.

The capsule ball 500 receives the food waste A therein and is introduced into the cooker main body 110 so that the high temperature heat applied by the drum heating unit 300 is prevented from being directly transmitted to the food waste A .

The food waste A contained in the capsule ball 500 is dried at a relatively lower temperature than the cooker main body 110 and discharged to the cooker main body 110.

5 (a) is a cross-sectional view showing a sectional configuration of the capsule ball 500 of the present invention. The capsule ball 500 includes a capsule ball body 510 forming a receiving space 520 in which the food waste A is received and a receiving space 520 extending from the surface of the capsule ball body 510, And a food inlet pipe 530 formed with a predetermined length toward the bottom of the body.

The capsule ball body 510 is formed into a spherical shape by superimposing two types of thin metal materials 511 and 513 having different thermal expansion coefficients. A first exhaust hole 511a and a second exhaust hole 513a are formed at positions corresponding to the first metal material 511 and the second metal material 513, respectively. Since the first metal material 511 and the second metal material 513 are not inflated with each other in a state in which no heat is applied as shown in FIG. 5 (b), the first discharge hole 511a and the second discharge hole The hole 513a is kept closed without being opened. As a result, the food waste A in the capsule ball body 510 is not discharged to the outside.

On the other hand, when the heat inside the pot body 110 is applied to the capsule ball body 510, the first metal material 511 and the second metal material 513 are expanded at different ratios. The capsule ball body 510 is bent while the first discharge hole 511a and the second discharge hole 513a are opened. As a result, the food waste A in a dried state in the capsule ball body 510 within a certain range is discharged into the pot body 110.

The dried food waste A dried in a certain range is stirred without being burnt in the pot body 110 and dried.

On the other hand, the food inlet pipe 530 is used to supply the food waste A to the capsule ball 500 from the outside of the food waste sludge sterilization and drying apparatus 1. The food inlet pipe 530 is inserted and fixed inside the capsule ball body 510. The food inlet pipe 530 is formed of a material that is not deformed even when heated. The food inflow pipe 530 is formed in the shape of a straight pipe and the side of the outlet 533 for discharging the food into the accommodation space 520 is formed in a curved shape.

By this, although the food can be moved from the inlet 531 to the outlet 533 by the pressure to put the food from the outside, the movement of the food from the housing space 520 toward the inlet 531 side can be controlled by the structure of the tube . Therefore, the food waste A contained in the capsule ball 500 is prevented from being trapped by the bimetal structure of the capsule ball body 510 until the first discharge hole 511a and the second discharge hole 513a are opened by heat And is then primarily dried in a state that it is accommodated in the container.

Meanwhile, the capsule ball 500 may be provided in a mesh shape as shown in FIG. 6 as well as a ball shape as shown in FIG. Food waste may be in the form of a gel with a lot of moisture, but it may be a form in which a lot of vegetables are mixed together. In this case, food waste is put into the pot body 110 as shown in FIG. 6 to secure the porosity between the food waste.

When the heat is applied, the food waste is crumbled as the water flows. The waste food waste, which is broken inside the mesh pipe, is discharged to the pot body 110, and further drying process proceeds.

7 is an exemplary view showing an operation structure of another embodiment of the capsule ball 500b. The capsule ball 500b of another embodiment opens and closes the discharge hole 561a by the bimetallic structure as in FIG. However, the second metal material 563 located under the first metal material 561 is provided with a blocking protrusion 563a for blocking the discharge hole 561a.

If heat is not applied, the blocking protrusion 563a closes the vent hole 561a as shown in Fig. 7 (a). When heat is applied in this state, the second metal material 563 is bent by heat and the blocking protrusion 563a moves downward. As a result, the discharge hole 561a and the blocking protrusion 563a are opened at a predetermined distance d, and the negative water residue A, which is primarily dried inside the capsule ball 500b at this interval d, And is discharged to the pot body 110.

Here, the food waste sludge drying apparatus 1 according to the present invention is dried until the moisture content of the food waste A is about 20%. When the food waste (A) is dried, it sticks together to form a lump. The food waste (A) dried in the 20% moisture range is discharged to the outside, and after the necessary nutrients are added to the livestock, it is post processed in the form of pellets.

In order to facilitate such additional processing, it is preferable that the dried food waste A is supplied in a pulverized state in the form of powder. To this end, the food waste sludge drying apparatus (1) of the present invention further includes a crushing ball (600).

FIG. 8 is a view showing various forms of the crushing ball 600, and FIG. 8 is an example of a process of crushing the food waste A after the crushing ball 600 is inserted.

The crushing ball 600 is provided with a sharp surface on its surface so as to contact the food waste A and grind the food waste A as shown in Figs. 8 (a) to 8 (c). For this, a polygonal shape, a star shape, and an irregular sharp shape are provided.

The crushing ball 600 is made of metal or stone, and the edges are sharpened.

The mixing ball 400 and the capsule ball 500 in the pot body 110 may interfere with each other when the food waste A is crushed using the crushing ball 600 or may be interfered with the mixing ball 400 by the crushing ball 600, The capsule ball 500 may be damaged. To this end, the food waste A, the mixing ball 400 and the capsule ball 500 dried before the grinding process are discharged into the pot body 110, the mixing ball 400 and the capsule ball 500 are separated, Only the food waste (A) and the crushing ball (600) are injected.

Meanwhile, the crushing balls 600c and 600d may be formed in a circular or oval shape as shown in (d) and (e) of FIG. 8. In this case, the crushing ball is formed of a heavy material such as stone or metal, and the dried food (A) is crushed by pressurization.

The operation of the apparatus for sterilizing and drying the food and beverage according to the present invention having such a configuration will be described with reference to Figs. 1 to 9. Fig.

The food waste (A) collected at a home or a restaurant is primarily subjected to foreign matter removal. Foreign materials such as vinyl, wood chips, hair, and the like are filtered through a conventional foreign matter removing device or the like.

The food waste A filtered by the foreign substance is introduced into the pot body 110 through the food inlet / At this time, the food waste A having a high moisture content is put into the capsule ball 500 and then introduced into the pot body 110. The food waste A is introduced into the outlet 533 through the inlet 531 of the food inlet pipe 530 of the capsule ball 500.

When the food waste A is put into the pot body 110, the mixing ball 400 is inserted. The input number of the mixing balls 400 is determined in consideration of the input amount and type of the food waste A, the size of the pot body 110, and the like.

Then, the detachable funnel net (160) is coupled to the food inlet / outlet (111).

At this time, the drum driving part 200 drives the driving motor 210 in a direction in which the stirring blade 130 puts the food waste A into the interior.

The heat generating part 310 generates heat when the opening and closing door 120 is closed. Then, the heat circulation fan 320 is driven. Heat is applied from the heat generating unit 310 and the heat circulating fan 320 circulates heat between the heat insulating cover 150 and the cooker main body 110. The heat is transferred to the pot body 110, which is made of a metal, and is moved along the center region of the pot body 110 and is evenly distributed to the entire food waste A inside. In this way, the food waste (A) inside is heated by heating for 30 minutes or more.

When the sterilization time for 30 minutes is completed, the opening and closing door 120 is opened and the drying process is performed. Heat is applied to the food, the water vapor discharged from the food is discharged to the outside through the food inlet / outlet 111, and the food waste is gradually dried.

The capsule ball 500 receives heat and the first discharge hole 511a and the second discharge hole 513a are opened as shown in FIG. 5 (b) And is discharged into the pot body 110. The food waste A stirred in the pot body 110 is sterilized and dried by far-infrared rays and heat applied from the mixing ball 400.

As the agitation continues, the food waste A in the pot body 110 gradually dries. When the moisture content of the dried food waste A reaches about 20%, the operator stops the driving of the drum driving part 200 and stops the driving of the drum heating part 300.

The drum driving unit 200 drives the driving motor 210 so that the stirring vane 130 rotates in a direction to discharge the dried food waste A therein. The dried food waste A, the capsule ball 500 and the mixing ball 400 are all discharged to the outside by the drive motor 210. The operator separates the capsule ball 500 and the mixing ball 400 from each other The food waste A is put into the pot body 110 again. At this time, the crushing balls 600 are put together.

The food waste A is further agitated together with the crushing balls 600, and the food waste A is crushed to a fine size. The finely ground food waste (A) is discharged to the outside of the sterilization drying pot (100), then the nutrients are replenished, processed into pellets, and supplied to the livestock feed.

As described above, the apparatus for sterilizing and drying food waste remnants according to the present invention dissolves heat only in one region of a sterilizing and drying pot and then dries the food. Accordingly, the amount of electricity or fuel required to dry food can be minimized.

At this time, since the mixing ball can be used to sterilize and dry the food, the drying time of the food waste can be shortened.

In addition, the gel-shaped food can be dried without burning using a capsule ball. At this time, since the food is discharged to the inside of the pot body in a state where the food is primarily dried in the capsule ball by using the bimetal principle, the drying efficiency of the food can be improved.

In addition, the disinfection and drying apparatus for food waste according to the present invention is characterized in that the disintegration ball without crushing device has a failure rate of the machine that is stronger than that of the crushing machine, It is to grind the food only by the turning force and the weight of the crushing ball which occurs during rotation of the main pot.

The embodiments of the device for drying sterilized food waste according to the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. .
