As shown in FIG. 3, the blower fan 600 is in-line coupled to the rotation shaft s together with the cutting blade 410 and the stirring blade 500 to generate wind power as it rotates to separate food and packaging materials. It serves to blow the air to the outlet 712 provided on one side of the fractionation container (700).

The blower fan 600 has a configuration in which a plurality of blower blades 620 are radially disposed on the outer peripheral surface of the shaft coupling part 610 that is shaft coupled to the rotation shaft s. Here, each of the blower blades 620 has a rectangular flat plate shape, and is configured by bending one end edge of one end in single or multiple steps in the direction of the outer circumferential surface of the rotation shaft s. Due to the blowing force and the shape of the inner peripheral surface of the fractionator 700, wind power, that is, a cyclone axial flow, is generated in the direction of the outlet 712 of the fractionator 700 from the mincing unit 400, so the packaging material in the fractionator 700 is discharged through the outlet ( 712) can be discharged.

On the other hand, the packaging paper for waste food and the food sorting device 100 according to the present invention is disposed under the sorting container 700 in the main body 200, as shown in FIGS. 1 and 2, and collects the food discharged from the sorting container.

The cover 720 includes a fixed cover 721 covering the upper side of the shredding unit 400 embedded in the semi-cylindrical 710, and the stirring blade 500 and the packaging material guide part 821 embedded in the separator 700. It may be composed of an opening/closing cover 722 that covers the upper side of the .

Here, the roll housing 310 is installed on the fixed cover 721 that cannot be opened and closed, and the opening and closing cover 722 that can be opened and closed is hinged to the body 200 and can be opened and closed as needed. It is useful when exchanging the internally built-in shredding unit 400, agitating blades 500, etc., and is also useful for removing foreign substances caught in the shredding unit and stirring blades.

In addition, the packaging material collection bin 820, the packaging material guide part 821, and one side wall of the main body 200 adjacent to them have wind exhaust for discharging the wind power generated in the fractionation bin 700 to the outside of the main body 200. Balls 820a, 821a, and 200a may be formed, respectively.

Hereinafter, the operation of the packaging paper for waste food and the food sorting device 100 according to the first embodiment will be briefly described.

When the packaged food to be discarded is put into the shredding unit 300, the packaged food that has been agglomerated while passing between the rotating pair of shredding rolls 320 is spread flatly and is primarily crushed by the crushing protrusion 322a. is made In particular, even in the case of tightly frozen packaged food such as frozen packaged food, even if it is put in immediately without thawing, the pair of crushing rolls 322a strongly crushes, thereby preventing damage to the shredding unit in advance.

Then, by the direction of rotation of the cutting blade 410 of the mincing unit 400 being rotated directly below the crushing unit 300, the primarily crushed packaged food is sliced in the longitudinal direction, so that the food and the packaging material are mostly separated. .

In this process, the lightweight packaging material is collected into the packaging material collection container 820 through the packaging material guide part 821 by the wind power of the blower fan 600 being rotated coaxially with the crushing unit 300, and the food is stirred by the stirring blade (500). ) is discharged to the discharge hole 711 formed in the lower part of the fractionation barrel 700 by the rotational pressure of the bin, and is collected by the food collection container 810 .

As described above, the separator 100 for packaged food of the first embodiment directly puts the packaged food in a hard state by freezing by the shredding unit 300 exerting a strong crushing force, without thawing the packaging material and the food. It has the advantage of being able to differentiate.

Next, a second embodiment will be described.

For reference, in the description of the second embodiment, the same numbers are assigned to the same components, and the overlapping configurations and functions will be replaced with the description of the first embodiment. Hereinafter, in comparison with the first embodiment, the parts having a structural difference will be intensively described.

7 is a perspective view of a packaging paper for waste food and a food sorting device according to a second embodiment of the present invention, and FIG. 9 is a plan view of a packaging paper for waste food and a shredding unit for a food sorting device according to a second embodiment of the present invention.

Referring to the above drawings, the packaging paper for waste food and the food sorting device 100 according to the second embodiment of the present invention is as shown in FIGS. 7 and 8 , a main body 200 , a crushing unit 300 , and a shredding unit 400 , as shown in FIGS. ), agitating blades 500 and a blowing fan (600). Here, the main body 200 , the crushing unit 300 , the stirring blade 500 and the blowing fan 600 may be configured. Since this configuration is the same as that of the first embodiment, other configurations not mentioned below are substituted for the description of the first embodiment.

The biggest difference from the first embodiment in the second embodiment is that the shredding unit 400 installed at the lower part of the crushing unit 300 is installed outside the main body 200, and a pair of shredding rolls 400a and 400b) The point is that they are installed to rotate symmetrically toward each other.

When the shredding rolls 400a and 400b are installed as a pair to be symmetrically rotated, the thinly shredded packaged food passing therebetween is shredded on both sides, thereby increasing the shredding efficiency compared to the first embodiment.

Each of the thinning rolls 400a and 400b may include a thinning shaft 401 and a plurality of thinning blades 410 fitted to the thinning shaft.

The fine cutting blade 410 includes a shaft coupling part 411 fitted to the fine cutting shaft 401 and a small cutting part 412 provided radially on the outer peripheral surface of the shaft coupling part, and the fine cutting part 412 ) may be composed of a root piece (412a) integrally formed with the shaft coupling portion (411), and a small piece (412b) detachably coupled to the end of the root piece.

In addition, the thin slices 412b and the other thin slices may be connected by a connecting bar 430 penetrating them.

In addition, a spacer 420 spaced apart between the cutting edges 410 may be interposed.

On the other hand, the chopping blades 410 between the two thinning rolls 400a and 400b may be alternately arranged to be shifted from each other by making a difference in the overlapping number of the spacers 420, and when viewed from the axial direction, the two thinning rolls 400a, A portion of the shredding blade 410 of 400b) is in a state of overlapping with each other, so that the packaged food passing therebetween can be effectively shredded.

In addition, the rotation speed of the two thin rolls 400a and 400b may be controlled to be different from each other. This was compared to the case when the speed of the two slicer rolls were the same, because the relatively slow slicer roll supports the packaged food, and the relatively high speed slicer roll drags the supported packaged food between the two slicer rolls. It can be a condition for more effectively dragging and entering packaged food.

Although the above-described embodiment has been described with respect to the preferred embodiment of the present invention, the present invention is not limited thereto, and it is specified that it can be changed and implemented in various forms without departing from the technical spirit of the present invention.
