Claims (5)

In the dryer for drying food waste,
The dryer and the casing to form an appearance; A plurality of disks arranged and rotated side by side at a predetermined interval inside the casing, and a disk in which hot steam circulates; A wing member formed on an outer circumferential surface of the disk to guide movement of food waste introduced into the casing; And a driving unit providing a driving force to rotate the disk.
The wing member is formed on the outer peripheral surface of the disk to guide the food waste in the direction of the flow of food waste, and the reverse blade formed on the outer peripheral surface of the disk to guide the food waste in the direction of the flow of food waste Including,
The drive unit includes a drive motor for providing a driving force for rotating the drive shaft, and a drive shaft connected to the drive motor at one end and the disk on the outer surface,
The forward wing is installed to have an angle of 20 to 70 degrees with the drive shaft when the dryer is viewed from the front, the reverse wing is installed to have an angle of 120 to 160 degrees with the drive shaft when the dryer is viewed from the front,
Since the food waste moves in the opposite direction to the flow direction of the food waste by the reverse wing, it is possible to slow down the passage speed of the food waste in the casing, thereby increasing the period in which the food waste is adjacent to the disk.
The wing member is formed on the outer peripheral surface of the disk further comprises a middle wing for stirring food waste,
The intermediate wing has a drying efficiency of the dryer with a forward and reverse blades, characterized in that installed horizontally with the drive shaft when viewed from the front of the dryer. delete The disk of claim 1, wherein the disc is
Ring type circular tube having a different radius is arranged to the outside at a predetermined interval, the vertical tube is connected to the circular tube in communication with the forward and reverse blades, characterized in that the drying efficiency is increased. A shredding compression unit for shredding, sorting and compressing food waste to remove food waste water; A drum separator for separating food wastewater separated from the shredding compression unit into a solid component and a liquid component; A dryer for drying the food waste from which the food waste water is removed from the shredding compression unit; A cooler configured to cool the food waste discharged from the dryer by using the liquid separated from the drum selector as cooling water; And an oil / water separator for separating the liquid discharged from the cooler into oil and water.
The dryer of claim 1 is used, and since the liquid separated in the drum separator is used as cooling water of the cooler and heated, the dryer is introduced into the oil / water separator so that the separation efficiency of oil and water from the liquid is improved. Food waste recycling apparatus equipped with a dryer having a forward and reverse blades, characterized in that the drying efficiency is increased. 5. The method of claim 4,
The drum sorter includes a filter drum in which the food waste water is introduced and a plurality of liquid discharge holes are formed on an outer surface thereof; A driving unit to rotate the filter drum and move the solid component separated inside the filter drum; Located at the outside of the filter drum at a predetermined interval, the high pressure washing nozzle for spraying a high pressure washing liquid toward the liquid discharge hole for a predetermined period; includes,
The high-pressure washing nozzle is located at the outer side of the filter drum at a predetermined interval, the washing liquid inlet pipe connected to the washing liquid supply device and the washing liquid is supplied, and a plurality of through-holes are formed at a predetermined interval on the outer surface of the washing liquid inlet pipe to wash the washing liquid. A washing liquid spraying hole for spraying the washing liquid inside the inflow pipe toward the liquid discharge hole,
As the filter drum is rotated by the driving unit, the liquid component of the food wastewater introduced into the filter drum is discharged to the outside of the filter drum through the liquid discharge hole, and only the solid component remains inside the filter drum. The high-pressure washing nozzle has a forward and reverse blades, characterized in that the solid component is prevented from being caught in the liquid discharge hole by spraying a high-pressure washing liquid toward the liquid discharge hole for a predetermined period of time to increase the drying efficiency. Equipped food waste recycling device.
