Description

Pellet Agitator {FELIT AGITATOR}

The present invention relates to a pellet agitator.

In general, when organic waste such as food waste discharged from restaurants, organic waste generated at industrial sites, and livestock manure and human waste generated in livestock houses is discharged without treatment, serious environmental problems occur in soil and rivers.

According to the conventional method, a method of recycling organic waste as feed or compost of livestock through a specific treatment process, a method of landfilling in a certain area, or a method of dumping in the sea have been mainly used.

In this case, there is a problem of low economic feasibility in terms of installation cost and maintenance cost of the treatment device.

Therefore, in order to solve these problems, various systems for improving environmental problems such as composting or pellet fuel using food waste, organic waste, livestock manure and human manure generated in livestock houses are being developed.

On the other hand, in the case of the above-described food waste, organic waste, livestock manure and human manure generated in livestock houses, pyrolysis treatment is required due to high moisture content, and a large amount of cost is consumed in the process of pyrolysis treatment.

Therefore, in order to treat moisture such as food waste, organic waste, livestock manure and human manure, organic waste is used as food for living things such as earthworms and housefly larvae, and fecal soil discharged from insects and larvae is used to treat moisture. It produces feed, compost and pellet fuel.

In this case, the discharged fecal soil has excellent inefficiency, so it can be usefully used for cultivation of agricultural land, horticulture, orchards, etc. It is known that it plays a role in increasing plant growth and yield of products.

However, since the fecal soil of insects and larvae also contains about 12 to 20% of moisture, there is a problem that it is not suitable for directly producing combustible pellet fuel through the fecal soil.
