Description

Food Waste Crusher {APPARATUS FOR GRINDING FOOD WASTE}

The present invention relates to a food waste crushing device, and more particularly, is installed in a sink of a restaurant or a general household, and finely crushes the generated food waste by a crushing device having a rectangular parallelepiped structure, and then, by the drying unit of the collecting unit. The present invention relates to a food waste crushing apparatus capable of pulverizing food waste quickly by sequentially crushing the food waste while discharging the dried food waste by a separable container in the crusher.

In general households or restaurants, food waste is inevitably generated. In the case of such food waste, various kinds and properties of the food waste are very difficult to dispose, causing various environmental pollution.

Therefore, in order to solve this problem, many devices for efficiently treating food waste have been developed and put into practice.

The prior art for the food waste treatment apparatus is largely divided into a screw type, a spin type dehydration type, and a hot air type drying unit.

The compaction device is simply dehydrated and compressed in a manner that the food waste is inconvenient in processing due to the volume of the finally produced waste, and frequent failure occurs when the screw is caught in food waste such as vegetables.

Unlike other devices, dewatering devices are noisy and are not suitable for home use because of their large appearance.

In order to improve this problem, a dry device has emerged, but a dry device also has problems such as consuming a lot of time, an imbalance in a dry state, and occurrence of odor.

Various food waste treatment apparatuses have been developed to overcome the problems in the single configuration of the apparatuses, and the conventional food waste treatment apparatus (Korean Registered Utility Model No. 0252432) has also attempted to solve this problem.

Specifically, the prior art has taken a small space, but combines the grinding means and the drying means to treat a large amount of food waste, remove odors, and extend the life of the machine.

However, there was a problem in this design, and since there is no drainage means, the function of the drying means cannot be fully maintained in the situation of moisture, and even in such a case, if you want to use such a device, separate efforts should be made to remove the water in advance. Entering, there is a problem that the grinding means is fixed in one form, there is no efficient grinding effect according to the type of food waste.

Another prior art is a food waste crushing treatment device (Korean Registered Utility Model No. 0319914). This invention is characterized by having a lifting unit for moving the grinding unit up and down to improve the problem of the conventional grinding means.

However, due to the direct connection with the drive motor, there is a possibility of cracking due to heat damage of the spline shaft in case of long-term use, and frequent failure due to the generation of shearing stress.

In addition, because it is designed to crush the food waste after the dehydration process, the grinding effect can be significantly reduced if the dehydration process is not performed, and food waste such as fiber is pulverized because the crushing means is fixed in one form as described above. It could be entangled in the means and cause a breakdown.

An object of the present invention for solving the problems according to the prior art, is installed in the sink of a restaurant or a general home, by crushing the generated food waste by a crushing device having a rectangular parallelepiped structure by the drying unit of the collecting unit The dry food waste is discharged by a separable container from the crusher, so that the hygienic treatment is possible, and the food waste crusher can be crushed in order to crush the food waste quickly.

The food wastes pulverized in the primary crusher 200 are more finely pulverized through the secondary crusher 300.

In addition, the secondary crushing unit 300 functions to squeeze the moisture remaining in the food waste while the food waste flows downward by the spiral grinding blade 310.

Here, the discharge valve 320 for discharging the crushed food waste to the outside is fastened to one side of the lower end of the spiral grinding blade 310, by opening and closing the discharge passage 322 by the operation of the discharge valve 320 To be discharged.

The discharge valve 320 is formed in the discharge passage 322 in communication with the collecting unit 500 on the lower side of the outer circumferential surface of the second grinding unit 300, the discharge passage 322 is inclined downward toward the collecting unit 500 side. Bring it out and discharge it smoothly.

This, the discharge valve 320 is operated by locking and opening, in the locked state the inflow path of the collecting unit 500 is blocked so that food waste does not flow out, in the open state discharge path 322 Discharge the food waste crushed to the collecting unit 500 side through.

In addition, the oil hole tube 330 inserted into the secondary grinding unit 300 in the longitudinal direction of the spiral grinding blade 310 is a direct structure associated with the drainage unit 400 and drains residual moisture. To form a plurality of flow holes 332 to be discharged to the side (400).

The water hole 332 has a function of discharging the residual moisture of the food waste crushed by the secondary crushing unit 300 to the drainage unit 400, the residual moisture introduced into the drainage unit 400 is water and Together with the drain pipe 20 of the sink.

The hole pipe 330 is configured on the lower side of the input unit 100 to collect the moisture of the food waste through the secondary crushing unit 300 through the moving air pipe 334, to flow into the water hole 332, The hole pipe 330 is in communication with the drain pipe (20).

Here, in one embodiment may be composed of a fine filter net 336 so that the food waste crushed through the water hole 332 does not flow into the drain 400.

At this time, the secondary crushing unit 300 has a predetermined moving space 334 that can move the residual moisture through the water hole 332 is located in the center of the cylindrical hole tube 330 inside the spiral grinding blade 310. It is to prepare on both sides.

In addition, the secondary crushing unit 300, the food waste is squeezed while flowing downward by the spiral grinding blade 310 is introduced into the oil hole tube 330 through the water hole 332 is drained.

As such, the secondary crushing unit 300 has a cylindrical body having a spiral crushing blade 310 on the inner circumferential surface, and is inserted into the secondary crushing unit 300 to have a small cylindrical oil hole 332.
