In general, food waste is a waste that is necessarily generated in large quantities accompanied with human eating habits.

Such food wastes contain a large amount of water and are discharged in a wet state. Since they are made of organic materials, they are easily decayed and generate odor and sewage.

As a result, food waste is difficult to separate, transport, and process. In the landfill process, a large amount of leachate and odor are generated to cause environmental pollution. In incineration treatment, the incineration temperature is lowered due to a high water content, There is a problem that the efficiency is extremely poor.

Recently, according to the Waste Management Act, it is prohibited to directly incinerate food waste generated in areas over the city.

As a result, food waste has been appropriately treated so as not to cause environmental pollution, and at the same time, a method has been sought to enable economic benefits by recycling the food waste. In order to safely dispose of food waste and recycle it, And feed conversion. To do this, it is first necessary to remove the water contained in the food waste as much as possible. In other words, in order to maximize the reduction and dehydration of food waste, it is necessary to carry out a series of pulverization, dehydration and drying processes. Therefore, the various food waste treatment systems and individual food waste treatment apparatuses Lt; / RTI >

The reason for crushing the food waste before drying is to reduce the amount of the food waste, and to improve the uniformity of the particle size, the agitation and the water leaching property so that the dehydration and drying can be performed smoothly thereafter.

In relation to such a technique, a conventional food waste disposal system is disclosed in Korean Patent Laid-Open Publication No. 2009-75916. As shown in FIG. 1, the food waste disposal apparatus 300 includes a waste disposal unit A first crusher 20 disposed at a rear end of the trash inlet 10 for crushing the introduced food waste into two rotary blades at a first stage and a second crusher 20 installed at a rear stage of the first crusher 20, A roller unit 30 for compressing primary food pulverized at a predetermined pressure and discharging the food waste to the next stage, and a pressurizer for loading food waste passed through the roller unit 30, A plurality of water discharge ports 41 are formed at the center of the motor 100 and a screw 110 for pushing the food waste by rotation of the motor 100 is inserted through the compressor 40, Is installed on the end of the 40 comprises a dryer 50, in which the moisture is removed, the food waste is dried crude product.
