By the way, looking at such a device, there is a problem that can be pulverized and dehydrated for the general food, but can not be processed for food with a high viscosity.

In other words, foods with high viscosity, such as bananas and sweet potatoes as compared to general foods, are adhered to the filter net during the processing through the screw shaft, resulting in the formation of mucous membranes. There is a problem that can not be discharged back through the back flow.

This problem not only pollutes the odor, but also pollutes the surrounding environment, causing mechanical failure.

The present invention has been made in view of the above-mentioned conventional problems, and its object is to spray back into the housing and feed water to food waste during dehydration to prevent backflow of water, which lubricates between the filter network and the screw shaft, thereby preventing backflow of odor. In addition, to provide a food waste disposal apparatus that can prevent mechanical failure in advance.

Another object of the present invention is to prevent the backflow of water that is sprayed into the housing when the hole of the strainer is blocked in the process of processing the food waste such as sweet potato, potato or bananas and hongsi containing a large amount of fiber in food waste. It is to provide a food waste disposal apparatus that prevents, but detects this in the reverse flow and automatically cut off the water supply to reduce mechanical failure and to effectively treat food waste.

An object of the present invention is a housing connected to the sink, and a crushing unit which is built in the housing and composed of a pair of grinding rolls to crush the food waste introduced into the housing. The food processing device is composed of a dehydration unit consisting of a screw shaft for transporting the food waste pulverized in the crushing unit and pressing to remove moisture, so that the screw shaft is installed in the state of being assembled to the front plate of the housing, A plurality of through holes are provided on the outer side, and the through holes are a cylindrical network whose inner diameter of the front side through holes is gradually reduced, and is integrally assembled or fitted to the distal end of the cylindrical network, and the tapered net has a plurality of through holes formed on the outer side thereof.

The scrapers 230 and 240 of the crushing unit are configured to be sandwiched between the crushing blades of the crushing rolls 210 and 220 in the state in which the crusher 230 and 240 are installed in the housing 100 so that the food sticking therebetween is detached.

In addition, the deodorization unit 300 is installed on the water outlet pipe is inclined in the front side, and consists of a screw shaft 310, the screw 311 is formed on the outer circumference.

The screw shaft 310 is a metal or synthetic resin injection molded configuration, the inclined portion 312 is provided on the front side, the lower side is connected to the transmission unit 400 in a state fitted to a bearing installed in the housing 100 It rotates and the screw 311 of the spiral protrudes on the outer periphery.

The screw 311 is configured such that the pitch gradually narrows as it reaches the front side from the rear, so that the food can be pressed by the interval of the pitch as the food moves forward.

The strainer 500 is composed of a cylindrical net 510 and a tapered net 520, each of which is to be made of synthetic resin or non-ferrous metal, they are integrally or prefabricated.

At the outer circumference of each of the cylindrical network 510 and the tapered network 520, a plurality of through holes 511 and 521 are formed at equal or irregular intervals, and the through holes are gradually smaller from the rear side. It consists of a composition.

In other words, the strainer 500 has a large opening at the start of the dehydration and a small opening at the end of the dehydration, which has a large inner diameter because the food waste is not pressured to exit the opening at the beginning of the dehydration. In the end part of the dehydration to which pressure is applied, the inner diameter of the through hole is made small to prevent food waste from escaping.

Preferably, the rear end of the cylindrical network 510, that is, the through hole at the beginning of the dehydration is configured to about 3.5mm, the interval is small by 0.5mm, for example, the end is formed less than 1mm through the end.

In addition, one end of the cylindrical network 510 is connected by the connecting portion 512 in the longitudinal direction, and the connecting portion has a single layer so as to form a path 513 through which food can be transported by the thickness of the single layer. According to the food is configured to move. This is to allow the screw shaft to be installed in the state closest to the remaining portion except the transfer path.

In other words, the outer diameter of the screw shaft 310 is configured to be substantially the same as or slightly smaller than the inner diameter of the cylindrical network 510 and the tapered network 520, so as to be assembled inside thereof, between the cylindrical network and the screw shaft 310 By minimizing the space to prevent food from being trapped inside the cylindrical network 510, the moving path 513 is provided downward to enable smooth movement.

On the other hand, the outer end portion of the cylindrical network 510 is provided with a flange 514 to be fitted to fit the front plate 110, the back flow prevention hole 530 is formed on the front side of the flange.

The prevention hole 530 has an inner diameter of at least 6 mm, the inner diameter of which the size of the mucosa that prevents the opening by at least the viscosity of the fiber or food waste does not occur.

In other words, the general food waste is finely crushed and moved through the grinding and dehydration process, but the food waste with high intrinsic viscosity blocks the through-holes to prevent the discharge of water to be described later.

For example, when sweet potato is put into water and heated, it gradually changes as the temperature rises. At first, these starch particles undergo a hydration process that absorbs water and absorbs a lot of water at a constant temperature of about 60 ~ 70 ℃. The swelling phenomenon, which becomes bulky several times, occurs, and the viscosity increases, resulting in a translucent paste.

This increased sweet potato blocks the through hole formed in the net in the process of moving along the cylindrical network 510 through the screw shaft 310 in the water combined state, wherein the prevention hole 530 is larger than the other through holes It does not cause mucous membranes or blockages, and allows the discharge of water to prevent backflow.

Of course, the water flowing out through the prevention hole flows into the flow path through the outlet hole 112 along the outlet pipe 130.

In addition, the prevention hole 530 is preferably formed on the end side of the cylindrical network 510 closest to the flange 514 assembled to the front plate 110, the food in the dehydration process of the screw and dehydration net This is because the garbage is located under the least pressure so that it does not leak out.

On the other hand, the water supply pipe 600 is to facilitate the dewatering of food waste by supplying water to the inner space 102 of the housing 100, the water is a general fluid or a separate fluid stored in the heavy water and the reservoir. Can be.

The water decomposes the food wastes that are pressurized through the crushing rolls 210 and 220 and lubricates the food wastes that are dehydrated under pressure between the screw shaft and the strainer.

The present invention made of such a structure is difficult to discharge water when it is difficult to drain water due to blockage of the perforated mesh in the processing of bananas with high fiber, viscous sweet potato, potato or hongsi in the process of crushing and dehydrating food waste. The operation process of preventing backflow is as follows.

First, when food is introduced through the drain trap 10, the motor 410 of the transmission unit 400 is operated by a user's arbitrary operation or monitoring sensor, the power is transmitted by the chain 430 and at the same time the grinding unit 200 and the dewatering device 300 is rotated to rotate. As they rotate, the food is pulverized by the grinding blades 211 and 221 while passing through the grinding rolls 210 and 220.

The crushed food is dropped into the space 102, the food waste dropped into the space is mixed with the water supplied through the water supply pipe 600 is introduced into the filter mesh 500 by the screw shaft 310 to be dehydrated.

The food waste moving forward by the screw shaft 310 is pressed between the screws as the pitch of the screw 311 decreases, so that the water is discharged through the through holes 511 and 521. As it flows down, the dehydrated food waste is moved to the discharge member 330 side.

In the process of treating sweet potatoes, potatoes or bananas containing a large amount of fiber, such as high viscosity, they are mixed with the water supplied to the housing 100 and expanded, and the viscosity is high, so that the through hole of the strainer 500 511 and 521 are blocked, so that the water supplied through the water supply pipe 600 is not discharged through the through hole.

In this case, the prevention hole 530 formed in the strainer 500 of the present invention discharges water that is not discharged through the through-hole to the discharge pipe 130 side, and the water flows through the drain hole 112 along the discharge pipe 112. It flows into) side to prevent backflow of water.

6 is a view showing another embodiment of the present invention, when the amount of water supplied is greater than the amount of water discharged through the backflow prevention hole 530, the water is filled in the internal space 102 of the housing 100. It senses and closes the valve installed in the transmission and pump or water supply line.

In other words, by installing the water level sensor 700 in the inner space 102 of the housing to detect the amount of water filling, and according to the signal of the sensor 410, pump 540 or valve (not shown) The control unit 710 for controlling the

As described above, the present invention, when food waste with high viscosity or food mixed with a large amount of fiber in the processing of food waste blocks the perforation of the filter cloth, water sprayed to the food waste to facilitate dehydration to prevent the backflow It is designed to prevent the occurrence of odor and mechanical failure due to the backflow in the water in advance, by providing a backflow prevention hole.

In addition, the present invention is to devise the water to be supplied to the inside of the housing when the water level is filled above a certain level, by detecting this, the motor and the water supply of the electric water to prevent the reverse flow and prevent mechanical failure in advance.
