A food waste solids collection and recycling system for recycling food waste into compost by composting through agitation.

In general, when food waste generated in homes or restaurants is left unattended for a long time, pests are generated and the environment of the house is deteriorated, so food waste generated when food is consumed is disposed of at a designated place.

In particular, in the case of food waste generated at home, due to the inconvenience of repeatedly dumping food waste in a designated place, a device for drying food waste in the home or pulverizing food waste installed in a sink has been developed, and these devices are It is stored in the installed food processor collection device and taken out to treat food waste.

Patent Document 1 relates to a conventional food waste and livestock manure processor. Referring to this, a hollow housing, a shaft installed horizontally in the housing and forming a plurality of paddles spaced apart at predetermined intervals on the outer surface thereof, and an inner bottom of the housing A discharge unit installed on the surface of the housing that transports food waste stirred in the housing and discharging it to the outside of the housing, and a dehumidification unit installed on the upper part of the housing that separates the liquid from the wet air generated in the housing and supplies dry air into the housing consists of units.

Here, food waste is introduced into the space through the inlet of the housing, and in that state, a shaft is rotated by a driving motor so that paddles formed on the shaft stir the food waste in the space.

At this time, the paddle formed on the shaft is composed of a second paddle wing formed on the outer surface of the shaft and a first paddle rod extending from the outer surface of the shaft toward the inner circumferential direction of the space of the housing and forming the first paddle wing at its end.

That is, as the second paddle blade is rotated by the rotation of the shaft, food waste close to the shaft axis is rotated in a forward or reverse direction while agitating, and at the same time, the first paddle blade formed at the end of the first paddle rod is the inner circumferential surface of the housing. Food waste accommodated in the space is uniformly agitated by rotating and agitating the food waste adjacent to the food waste in the forward or reverse direction.

In addition, as food waste is stirred in the housing, wet air is formed in the space, and the wet air is supplied to the liquid separator through the exhaust pipe of the dehumidifying unit, and the liquid contained in the wet air is separated in the liquid separator. The dry air separated from the liquid is re-supplied into the housing through the supply pipe.

Then, the dry air is continuously introduced into the housing, and thus, the food waste accommodated in the housing is dried by the dry air.

Thereafter, the food waste dried in the housing is supplied into the discharge unit. At this time, the screw driver rotates the screw, and the dried food waste is transported in the direction of the discharge pipe by the screw and discharged through the discharge pipe.

However, Patent Document 1 as described above has the inconvenience of separately separating water from food waste and inputting it into the housing, and when food waste containing water is introduced into the housing as it is, the moisture contained in the food waste is removed. It takes a long time to evaporate, and in the process of drying food waste containing moisture, an excessive amount of wet air is supplied to the dehumidifying unit, making it difficult to separate the liquid contained in the excessive amount of wet air with a liquid separator. The function of the liquid separator is lost due to wet air, and there is a possibility that wet air will flow into the housing as it is, and the drying time of food waste is frequently changed according to the amount of food waste in the housing, so the drying time of food waste is irregular. There is a problem in that the garbage drying performance is lowered and the reliability of the product is lowered.
