Description

Electric food grater {ELECTRIC FOOD GRATER}

The present invention relates to an electric food grater, More particularly, the invention relates to an electric food grater capable of easily making a dessert or a baby food by scraping off foods such as vegetables, fruits or boiled grains through a grating roller.

Generally, household grinder grinds food through a rotating blade at high speed, so that the vitamins contained therein are destroyed. The tough fibers and the husks remain as large particles (grates) I can not. In order to overcome such disadvantages, a juice blender has recently been adopted which adopts a filter screening method, which is configured to filter the rough juice filtered through the screen by filtering it through the screen. However, in the filter screening type mixer, only the small particles that can be filtered out through the filter screen come out, and the coarse and thick juice remains in the filter screen. After all, a large amount of liquid juice is left intact inside the sieve, so it can not be consumed.

Further, a juice juice for domestic use to which a screw is applied is disclosed in Korean Patent No. 10-0755440. The vertical juice juice dispenser of Patent No. 10-0755440 includes a lid 10 having an inlet 11 formed at an upper portion thereof and having a rotary shaft hole 12 formed at the center thereof, A housing 50 provided at a lower portion of the housing 10 and formed with a dust outlet 51 and a juice outlet (not shown) at a lower outer end thereof and a waterproofing cylinder 52 at a central lower end thereof; A vertical screw 20 rotatably inserted into the hole 12 and having a plurality of screw spirals on the outer surface thereof, a wall drum 20 having a net structure for discharging the juice, and a plurality of wall blades formed on the inner surface thereof in a vertical direction, A rotary brush 30 mounted between the housing 50 and the net drum 30 and having a brush holder mounted thereon so as to continuously sweep the net drum 30 and the housing 50 while rotating, 40 through the through holes of the waterproof cylinder 52, And a driving unit 60 for rotating the screw 20 at a low speed. Therefore, since the housing 50 accommodating the screw 20 is vertically fixed on the upper side of the driving unit 60, the food material introduced through the inlet 11 is compressed and crushed through the screw 20, Respectively.

However, in the juice juice unit disclosed in the above-mentioned Patent No. 10-0755440, the food materials are crushed to be juiced, and the soft fruits such as tomatoes and oranges are juiced, while in the case of hard materials such as soybeans and pomegranates, There is also a disadvantage that the residue is much more than expected and its efficiency drops. In particular, the fibrous component of the foodstuff is largely discarded as debris. In addition, even when the vegetable juice is squeezed, the juice extraction is not smoothly carried out in the stem due to the large amount of the residue. This is because the juice is made by crushing the material through the extremely short process distance which is finished by two to three rotations of the vertical screw to be.

The present invention has been made to solve such a problem, An object of the present invention is to provide an electric food grater which is rich in fiber and can be produced smoothly by eating, as well as being able to feel the natural texture of a food material by scraping and discharging a food material to be injected in the form of an appropriate size .

(At this time, the user can continuously push the ingredients through the push stick 500 (see FIG. 2).) The ingredients are scratched by the grating cutters 320 of the grating roller 300 and become fine pulp, which is discharged to the outside through the discharge port 220.

More specifically, as shown in FIG. 11, as the grating roller 300 rotates, the inputted ingredients are scratched by the grating cutters 320. And the scraped food particles are agglomerated again between the inner wall of the housing-drum 200 and the wall surface of the rotating grating roller 300. The soft and fine pulp (roughly slush form) I get out through. Particularly, the brushing teeth 230 (see FIG. 7) arranged on the inner wall of the housing-drum 200 continuously sweep between the dividing grooves 321 (see FIG. 9) of the grating cutters 320, (Not shown). Further, the brushing protrusions 260 provided on the inner wall of the lower portion of the housing-drum 200 adjacent to the rear portion of the discharge port 220 sweep the wall surface of the grating roller 300 once again, so that the introduced food material is efficiently scratched and broken And is discharged downward through the discharge port 220 in the form of a slush containing a lot of juice. When food ingredients are put into the electric food grater according to the present invention, they are discharged into a pulpy slush containing a large amount of liquid juice. Therefore, the present invention can be utilized for making fruit ice cream or baby food.

Meanwhile, when the electric food grater according to the present invention is used, the housing-drum 200 coupled by a twist lock method is rotated by a predetermined angle in the open direction, The housing-drum 200 is easily separated from the drum seating portion 120. [ Subsequently, the sealing cap 400 and the grating roller 300 can be sequentially removed from the housing-drum 200 and disassembled (refer to FIG. 5). When the grinding roller 300 and the sealing cap 400, which are disassembled here as well as the housing-drum 200, are cleaned directly by the washing water and then assembled in the reverse order of decomposition, the cleaning of the electric food grater according to the present invention Is completed. In particular, the housing-drum 200 in which the grinding roller 300 and the sealing cap 400 are accommodated can be easily disassembled and assembled in the main body 100 without any special knowledge or tools.
