In general, with the increase of population, the acceleration of economic development and the increase of the national income, the standard of living of the people is improved, but the pollution of the environment is accelerating, among which the treatment of food waste is a serious problem.

The food garbage contains a large amount of water, has a toxic odor, and is difficult to treat, such as propagation of insect pests. Therefore, it has been disposed of in the sea or buried in soil.

As described above, there is a problem in that the method of filling the food garbage and treating it is costly, but the environment around the landfill is severely damaged due to pollution of the soil and groundwater due to leachate and odor.

Moreover, in recent years, marine dumping, such as leachate of food waste, has been banned by the law and the treatment has become very demanding.

In order to solve the above-mentioned problems, conventionally, food waste is put into a chamber and heat is applied to completely remove moisture, and then the food waste is buried or burned to be buried or burned, and a food garbage disposal apparatus is provided.

Recently, there has been provided a food garbage disposal apparatus in which pellets are made of processed powder and the garbage can be recycled as a raw material for treating food garbage, thereby drastically lowering the processing cost.

Conventional food garbage disposal apparatuses have been disclosed in Korean Patent Registration Nos. 0702602, 849672, 1125024, and 20140-0012499.

However, the conventional food garbage disposal apparatus has the following problems.

(2) Even when a large amount of fuel and energy is applied, the treatment rate is significantly lowered, and therefore, there is a limit in treating a large amount of fuel.

In order to solve the above-mentioned problems, the present invention is characterized in that a tank for collecting food waste is formed, a breaker for breaking food waste supplied from the tank is formed, and foreign matter is removed from the food waste broken in the breaker An input device in which a particle eliminator is formed and a crusher for crushing while removing foreign matter from the food waste broken in the crusher is formed;

A boiler for burning pellets to form a burner for generating a heat source and generating steam by the burner;

A chamber in which food waste is injected from the charging device is formed, a space for supplying steam to the periphery of the chamber is formed, a steam pipe for supplying steam is formed in the center, and steam is supplied to the periphery of the steam pipe A plurality of drying coils are formed, and the steam pipe and the drying coil are configured to rotate by a motor;

A pelletizing device formed at a lower end of the dryer to pressurize the dried food waste to form pellets;

And a gas processing device connected to the dryer and connected to the steam and the gas discharged from the dryer by a transfer pipe,

And the dryer is operated in a low vacuum state in a sealed state.

According to the food waste pelletizing apparatus using the low vacuum of the present invention, the following effects are produced.

(1) Since the treated food waste is re-manufactured into pellets and used as fuel, it is energy-efficient and requires no additional cost.

(2) Because it is operated in a low vacuum, the water vapor generated from food waste quickly dries out, drying time is significantly reduced.

A wastewater tank for storing wastewater discharged from food waste is separately formed in the lower portion of the tank 210. Wastewater from the wastewater tank is introduced into the chamber 110 by a pump and a connection pipe.

The breaker 220 is formed to tear the wrapping paper containing the food wastes so that the food wastes can be separated.

The pulverizer 230 is formed to pulverize the food waste and cut into granules so that the food waste can be dried well in the dryer 100.

The boiler 300 has a boiler body 320 and a burner 310 is formed at one side of the boiler body 320 to pass through the inside of the boiler body 320.

The boiler body 320 is formed by the burner 310 to generate steam.

The burner 310 has an inner chamber 311 formed with a helical frame part 311a in front and a combustion burner 312 passing through the inner chamber 311 is formed at the rear of the inner chamber 311, A pellet injection pipe 313 into which pellets are injected is formed at an upper end of the chamber 311 and is projected from the rear of the inner chamber 311 so as to disperse the pellets falling from the pellet injection pipe 313, A dispersion rod 314 is formed.

A plurality of air holes 311a are formed in a peripheral wall of the inner chamber 311 and a blowing portion 315 surrounding the periphery of the inner chamber 311 and air is flowed by a plurality of blowers 315a is formed do.
