[0043] Working principle:

[0044] In use, the food waste is put into the feeding pipe 2, and the food waste enters the separation box 1 through the feeding port.

[0045] Starting the first motor 4, the output shaft of the first motor 4 rotates forward. The lead screw 6 rotates to drive the connecting plate 7 to move downward, the long rod 5 slides through the top surface of the separation box 1 to move downward, and the pressing plate 16 slides downward on the outer surface of the filter cylinder 14.

[0046] The pressing plate 16 drives the four movable plates 15 to move downward together, and the bottom end of the movable plate 15 will first contact the food waste. Then the pressing plate 16 continues to move downward, the pressing plate 16 drives the hinged end of the movable plate 15 to move downward, so that the movable plate 15 gradually tends to be horizontal, and the torsional spring is twisted.

[0047] The pressing plate 16 continues to move downward, and the pressing plate 16 and the movable plate 15 will together extrude the food waste downward, so that the water in the food waste passes through the filter holes on the filter cylinder 14 into the filter cylinder 14.

[0048] During the extrusion of the pressing plate 16, food waste can be added to the separation box 1 through the feeding pipe 2. The food waste falls on the top of the movable plate 15.

[0049] Starting the water pump 8, the water in the filter cylinder 14 enters the water inlet pipe 19, and then enters the inside of the centrifugal cylinder 18 through the water outlet pipe 17.

[0050] Starting the second motor 9 to rotate the centrifugal cylinder 18, so that the water falls on the filter plate 13, and then flows to the bottom end of the filter box 11. Starting the drainage pump 12 can drain the water at the bottom end of the filter box 11.

[0051] After the extrusion of the pressing plate 16 is completed, the first motor 4 is started, and the output shaft of the first motor 4 reverses. The lead screw 6 rotates to drive the pressing plate 16 to move upward, and the hinged end of the movable plate 15 moves upward.

[0052] The movable plate 15 moves upward, and at this time, under the action of the gravity of the food waste, the movable plate 15 rotates downward, so that the food waste falls to the bottom end of the separation box 1.

[0053] After the food waste falls, under the action of the torsional spring, the movable plate 15 is driven to rotate, so that the movable plate 15 is in an inclined state to facilitate the continuation of the extrusion work.

[0054] After use, the maintenance door 10 is opened to clean the centrifugal cylinder 18 and the filter plate 13. The discharge baffle 3 is opened to move the pressed food waste in the separation tank 1 out.
