The food waste inside the drying unit 60 measured by the food detection sensor 12 has a predetermined reference capacity (in this case, the reference capacity is determined according to the processable capacity of the drying unit 60). When exceeding, the operation of the screw driving motor 51 is temporarily stopped under the control of the microcomputer to prevent the food waste inside the secondary screw housing 40 from flowing into the drying unit 60 any more. Let's do it.

Thereafter, when the food waste inside the drying unit 60 measured by the food detection sensor 12 is less than or equal to the predetermined reference capacity, the screw driving motor 51 is operated again under the control of the microcomputer. Let's do it.

This prevents stagnation of the food waste in the food waste processing apparatus due to the excess amount of the food waste processing capacity of the drying unit 60, thereby enabling a smooth food waste treatment without adding excessive force to the apparatus.

Food waste treatment process and effect according to the present invention

The processing movement path of the food waste and the water contained in the food waste by the food waste processing apparatus of the double rotating screw structure according to the present invention is as follows.

As shown by the solid arrow in FIG. 3, the food waste introduced into the inlet 10 is first crushed and compressed in the primary screw housing 30 provided with the primary rotating screw 31 via the inlet 10. And dehydrated, followed by secondary grinding and compression of the secondary screw housing 40 with the secondary rotating screw 41 and dehydration, followed by drying through a food outlet formed in the secondary screw housing 40. It moves to the part and / or the receiving part.

At this time, the moisture contained in the food waste, as indicated by the dotted arrow in Figure 3, the food waste is crushed and compressed in the primary screw housing 30 provided with the primary rotating screw 31 It is dehydrated through the process to be discharged through the water outlet 35 formed in the primary screw housing. In addition, moisture, which is not discharged from the primary screw housing 30, is crushed and compressed again in the secondary screw housing 40, and dehydrated to dehydrate the primary screw housing 30 or the secondary screw housing 40. It is discharged through the water outlet 35 formed in).

Next, the operation process, operation and effects of the present invention food waste disposal apparatus of the double screw structure will be described in detail.

First, food waste is introduced into the primary screw housing 30 through the food inlet 10.

The food waste inside the secondary screw housing 30 is transferred toward the partition 33 by the forward rotation of the primary rotating screw 31 which rotates by the forward rotation of the screw drive motor 51 and is crushed. Compressed and dehydrated.

At this time, the dehydrated water is removed through the water discharge hole 36 formed in the primary screw housing 30.

The food waste, which is crushed, compressed and dehydrated by the forward rotation of the primary rotating screw 31, is closely adhered to the partition 33 and compressed, and the food waste is formed through the food inlet 34 formed in the partition 33. Flows into the primary screw housing 40.

In this process, the food waste that has passed through the food inlet 34 formed in the partition 33 is more finely cut by the rotation of the cutting blade 43 and finally into the secondary screw housing 40. Inflow.

The food waste introduced into the secondary screw housing 40 is transferred toward the discharge surface 46 by the forward rotation of the secondary rotating screw 41 and is crushed and dehydrated again.

The dehydrated water flows down into the primary screw housing 30 through the food inlet 35 formed in the partition 33 and then opens the water discharge hole 36 formed at the lower end of the primary screw housing 30. Is removed. If the water discharge hole 36 is formed at the lower end of the secondary screw housing 40, the dehydrated water may also be removed through the water discharge hole 36.

The food waste, which has been crushed, pressed and dehydrated in duplicate by a double screw of the first and second screws 31 and 41, has a discharge groove 49 formed in the discharge surface 46 and the food discharge port 45. It is introduced into the drying unit 60 through).

At this time, when the food waste is introduced into the drying unit 60 by the food sensor 12, the heater and the stirring motor 63 start to operate, apply heat to the food waste, and dry and stir the work. Proceed.

In this case, the blowing fan 66 is operated together to blow the internal air of the drying unit 60 to further promote the drying of the food waste.

Finally, the food waste that has been dried and stirred in the drying unit 60 flows into the storage unit 80 installed at the lower end of the drying unit 60, thereby collecting the food waste. .

As described above, the food waste treatment apparatus of the double screw structure according to the present invention, as compared to the conventional food waste treatment apparatus having a single screw structure is subjected to a double-crushing compression and dehydration process to a low power and It has the effect of maximizing the drying efficiency by doubling the food waste disposal capacity with high efficiency and at the same time drastically reducing the drying time.

In particular, the conventional food waste treatment apparatus having a single screw structure takes 12 to 24 hours in the drying process and causes a bad smell, whereas the food waste treatment apparatus of the double screw structure according to the present invention has a drying process. This will end in 2 hours and the odor is also reduced by that much.

That is, by the food waste treatment apparatus of the double screw structure according to the present invention, it is possible to treat food waste with eco-friendly, low power and high efficiency.
