Description

Food Waste Disposal Device {FOOD WASTE DISPOSER}

The present invention relates to a food waste treatment apparatus, and more particularly, to crush, dehydrate, and dry food waste more efficiently.

As is well known, food waste is a kind of waste that is generated by human life.

Food wastes contain 80 to 85% of water in large quantities and are discharged in a wet state, and because they are organic, they easily rot and generate odors and sewage. Therefore, the separate collection, transportation, and treatment are very difficult, and at the time of landfill treatment, a large amount of leachate and odor are caused to cause environmental pollution. In the incineration treatment, the heat generation amount was very low due to the lowering of the incineration temperature due to the high water content, and the efficiency thereof was extremely poor.

In recent years, the direct disposal of food waste generated in more than one unit area is prohibited by the Waste Management Act.

Therefore, food waste must be properly disposed so as not to cause environmental pollution, and appropriately recycled to generate economic benefits.

The safe treatment and recycling methods include fueling, fertilizing and feeding, and in order to smoothly achieve such treatment, it is necessary to first remove water contained in food waste as much as possible. In other words, in order to reduce and dehydrate food waste as much as possible, a series of grinding, dehydration and drying treatments should be performed.

Of course, the various food waste treatment systems and individual food handlers that are currently developed are processed by crushing and dehydrating and drying the food waste.

The reason why the food waste is pulverized before drying is to reduce the amount and to improve the uniformity of the particle size, the agitation, and the water elution so that a smooth dehydration and drying can be performed thereafter.
