Generally, food processing methods are based on landfill and incineration, but landfill depletion and environmental problems are generated, and the amount of final disposal is reduced, but there are environmental problems such as dioxins generated during incineration and high cost problems have.

The best way to deal with food waste is to reduce emissions as much as possible. To this end, the government recently amended the relevant laws to charge fees differently depending on the weight of food waste discharged in relation to the discharge of food waste.

In order to reduce the amount of food waste, it is preferable to dehydrate and dry the food waste. In particular, food waste can be recycled as an organic material, but it requires a desalination process.

Salinity in food waste causes environmental problems when landfilling or incineration, and when the salinity is above 1%, the growth disorder of the plant due to the osmotic phenomenon and the replacement of Na with Ca and Mg in the soil, It is impossible to compost the food waste without removing the salt because the oxygen supply becomes difficult due to the badness of the ventilation and drainage due to the disintegration of the food waste. The content of salt in the product is regulated to 1% or less.

Accordingly, various household food and beverage processing machines are commercially available but are not satisfactory in order to efficiently process the food and to reduce the amount of the generated food.

However, since the conventional desalination technique requires a large-scale system, it is inadequate to treat food waste generated in small quantities in each home or business, and a method for effectively treating desalination in each household has been required.

In the "Small Capacity Food Drying Processor " of Korean Patent Laid-Open Publication No. 10-2012.0140376 dated December 3, 2012, food waste is cut by a cutter formed into a double cutter and crossed with a circular stationary plate, And the residue is less than the hole of the perforation is dropped down by the rotational motion of the cutter fixed to the rotary shaft and is compressed and dewatered by the lowered interlocking rotating impeller, The opening / closing disk is opened, and the impeller rotates to fall into the drying cylinder of the drying unit. On one side of the drying cylinder there is a hot air blowing the heated heat to the inside of the drying cylinder by the fan, The dried residue is rotated by the cutter at the lower end of the stirring shaft in the center of the drying cylinder. Up and down a lower outlet of the drying cylinder by moving the piston is configured to be housed therein disclosed fall into opened.

However, in the above-mentioned patent, there is a problem that dehydration can not be performed smoothly due to the food being caught in the hole in the dehydration process, and desalination can not be effectively performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown.

1 to 5, a food garbage disposal apparatus 1 according to an embodiment of the present invention includes a dehydration unit 10 for desalting and cutting food garbage at an upper portion thereof, And a crushing unit 40 for crushing and discharging the food waste discharged and desorbed from the dehydrating unit.

The dewatering unit 10 includes a dewatering tank 11 as a case, a sieve net 12 having a multi-mesh network structure disposed inside the dewatering tank 11, A sweeper 13 arranged to rotate in contact with the inner side of the sieve to sweep the inner side of the sieve in order to solve the deteriorated problem, and a safety inlet 14 connectable to the drain of the sink.

A plurality of protruding portions 15 extending radially inward are formed in the input port 14 so that the protruding portions 15 do not enter into the protruding portions when the user inserts his or her hand.

The sieve net 12 is provided with a plurality of holes in the form of a cylinder formed on the side and bottom and supported by a support provided in the dehydration tub at the center of the bottom surface, And the dehydrated food waste that has entered the filtering net through the inlet is dehydrated while being rotated at a high speed by the extended output shaft of the main motor 44 which drives the cutter 41 of the filter.

The water sprayed from the plurality of nozzles 18 provided on the dehydrating tub side portion in the dehydrating process drops off from the side of the filtering net toward the food garbage attached to the inner side of the tub by the centrifugal force when the tub is rotated, The dilution of salt and the dehydration by water spray from the nozzles are repeated so that the desalting action of the food waste is improved.

An end portion 23 of the bottom of the sieve net constituting the outlet is formed to be in close proximity to the bottom surface of the dewatering tank, preferably in a range of 0.2 to 0.5 mm The food garbage on the bottom of the sieve net is caught by the centrifugal force to the side of the side of the sieve net as well as the open side of the sieve net bottom, The food waste is subjected to dehydration and desalination by being pushed into the sieve by the inclined end 23 of the open outlet of the sieve at the high speed rotation of the sieve. As an alternative to the inclined end portion, a sloped spatula portion of a silicon material may be formed.

The sweeper 13 disposed on the inner side of the sieve includes an annular lower ring member 25 connected by a plurality of horizontal support members 24 in a radial direction at the central portion thereof, And an upper ring member 27 integrally formed on the upper ends of the vertical support member 26 and the vertical support member 26. [

In order to rotate the sweeper, a top portion of the upper ring member 27 is formed with a toothed portion 36, to which gears 16, 16 'arranged at at least two opposed positions are engaged, The gear 16 is driven by a motor 17 provided outside the dewatering tub to rotate the sweeper and the gear 16 'disposed on the opposite side to the gear 16 is mounted idling inside the dewatering drum, So that the sweeper is stably rotated without being inclined to one side, and the sweeper is disposed so that the center portion of the bottom surface of the sweeper is rotatable about the center of the dewatering tank.

The sweeper is configured such that a vertical support member (26) vertically connecting the upper and lower ring members (25, 27) is in contact with the inner side of the water line to sweep the inner side of the water line when the sweeper is rotated to squeeze food waste So that the food garbage is not discharged into the dehydrator in a state where the debris is not desalted and dehydrated.

Further, the horizontal support member 24 radially formed in the lower ring member 25 of the sweeper is rotated close to the bottom of the sieve 12 during rotation of the sweeper. The cutter 28 is fixed to the horizontal support member of the lower ring member 25 and is rotated together with the sweeper to cut the food waste in the filter net as a pretreatment before crushing the food waste in the crushing unit 40 .

In the drain mode in which the food debris drained and desorbed in the drainage network is discharged to the crusher provided at the lower side, the drainage network is stopped and the sweeper is rotated at a low speed. At this time, the gate 30, which is openable and closable as a part of the bottom of the drainage trough, The horizontal support member 24 acts as a scraper for discharging the dehydrated food waste accumulated on the bottom of the sieve net to the crushing section 40 through the opened gate 30 of the dewatering cylinder.

For this purpose, the sweeper is kept stationary when the sewing network is rotated at a high speed for dewatering, but rotates at a low speed when the sewing network is stopped. As a result, when the sewing network is rotated at a high speed, The food waste is firstly cut by the cutter provided at the center of the horizontal support member. When the dewatering operation is completed and the sieving operation is stopped, the sweeper rotates at low speed and the vertical supporting member drops the food waste from the side of the sieve net to the sieve bottom floor, and the food waste on the bottom of the sieve net is formed on the lower side ring member And is discharged to the crushing section 40 through the gate 30 opened at a part of the bottom of the dewatering container by the scraping action of the horizontal support member 24. [

Thus, the sweeper can maintain the dehydration performance by preventing food debris from being removed from the inner side surfaces and the holes, thereby preventing food debris from being interfered with the dehydration operation.

The dehydrating tube (11) is provided with a dehydrating tube (19) for discharging dehydrated water from the tub, and a dehydrating tube (20) is disposed in the dehydrating tube to allow the dehydrating tube So that the food waste in the sieve net is desalted to improve the desalination efficiency.

The gate 30 provided at the bottom of the dewatering tank to be openable and closable is integrally formed at the upper end of the worm 33 on one side of the bottom surface and the worm 33 is mounted on the inside of the upper portion of the crushing section 40 And is rotated by the worm gear 34. When the worm 33 is rotated by the worm gear 34 by screwing the shaft 29 with a screw in the hole of the worm 33, the worm 33 ascends and descends around the shaft 29, And an open position for discharging the food waste downward. The shaft portion 29 is supported in an idling state at an extended output shaft of the main motor 44 driving the main cutter in the crushing portion 40 and is engaged with the worm gear 34 so as not to rotate at the time of driving the main motor, As shown in Fig.

As described above, the dewatering unit of the food garbage disposal apparatus according to the present invention has a sweeper disposed inside the sieve filter to clean the sieve filter to maintain the dewatering performance. Water is introduced from the water tank by the washing water injection nozzle, The discharged food waste can be recycled as compost or the like.

As shown in the cross-sectional view of the low-water cistern 20, a valve 35 is provided at a central portion thereof. The valve 35 includes a low-water cistern, and water is supplied to the dehydrator 19, Has buoyancy preset so as to be opened only to the above-mentioned water level without being opened until the rush. Thus, only when the dehydrated water becomes higher than the level of the dehydration discharge pipe 19, the valve 35 is opened and discharged from the reservoir 20. Therefore, the water in the dehydration reservoir, which is partially filled with water at the height of the dehydration discharge pipe, So that the desalting action can be performed more efficiently.

The crushing unit 40 disposed below the dewatering unit is provided with a cutter driven by the main motor 44 so as to desalinate and dewater in the dewatering unit on the upper side to crush the food waste flowing through the opened gate. The structure of such a crushing unit is partially shown in the drawing, but does not constitute the gist of the present invention, and thus a detailed description thereof will be omitted.
