Description

Food waste shredder

The present invention relates to a food waste crushing apparatus, and more particularly, the food waste collected in a restaurant or at home is automatically crushed and stirred sequentially so that no residue remains, and such agitates are completely extinguished through the microbial fermentation process. The present invention relates to a food waste pulverizing device (Food-scrap pulverator) which deodorizes odor generated from food during fermentation and is discharged to the outside to greatly contribute to preventing environmental pollution.

In recent years, food waste has increased due to the improvement of consumer's income level and the diversification of dietary culture.As a result, households and large amounts of food waste are generated in Korea to solve the serious environmental pollution problem. It is required to install food waste reduction facilities in restaurants, etc., and is actively promoting ways to reduce garbage by implementing a waste-based system.

In the conventional waste disposal method of a home or a restaurant, the garbage containing foods is first collected in a bag for collection, and then stored in a common waste storage room around the house, and the garbage disposal worker is repeatedly transported to a predetermined place. It is classified as recyclables and incinerated waste. Then, the sorted waste was recycled by reducing the volume with a compressor and then recycled or incinerated or landfilled at a predetermined place.

If the food waste collected as described above is stored in a collection bag or a garbage storage place for a predetermined time, it causes an environmental pollution by causing a bad smell. Also, if the food waste is landfilled in the process of processing the collected food waste, However, sediment water will flow into the groundwater and cause soil and water pollution.

In addition, if you want to dispose of food waste collected in the same way as above, even if you want to dispose of it in a facility suitable for disposing of food waste, you need to go through several steps. This causes a problem that the economic efficiency is greatly reduced.

In addition, when the food waste is incinerated, there is a problem that the environmental pollution caused by the emission of pollutants due to the smoke and landfills generated during incineration.

Therefore, the present invention was devised to solve the above problems, and the food waste collected at home or in a restaurant is automatically extinguished at the same time as the collection, thereby eliminating unnecessary workforce and equipment or processing time delay due to food waste disposal. The purpose is to provide a food waste shredding device that is conducive to the reduction of economic costs by contaminating pollutants and contributing to the prevention of environmental pollution.

Another object of the present invention is to enable the food waste shredder of the present invention to be manufactured in various sizes according to the amount of garbage collection such as a general home or a restaurant to achieve the ease of installation and ease of use.

Referring to the operation state of the food waste crushing device according to the configuration in detail as follows.

In order to dissipate the food waste collected at home or restaurant, first open the hopper 12 provided in the extruder (A) as shown in Figure 1 and then put the food waste.

Then, when driving the motor 14 of the extruder (A) shown in Figure 1 by the rotational force of the pulley 17 of the motor 14, the screw conveyor 13 connected to the belt 18 is rotated, The rotating screw conveyor 13 horizontally transports the introduced food waste into a predetermined amount and feeds it into the pulverization container 20 of the crusher B provided at the outlet end of the extruder A.

The food waste falling into the grinding container 20 in a continuous operation causes the multi-stage grinding blade 22 shown in FIG. 2 to rotate as the motor 23 of the grinder B rotates the rotary shaft 21. do. At this time, the solid material that is dropped while the primary grinding blade 31 provided on the upper side of the rotary shaft 21 is horizontally rotated is cut into an appropriate size, and the grinding material that is cut and dropped is dropped on the secondary grinding blade 32 using centrifugal force.
