[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model involves adding crushed debris into an extraction and separation tank, then adding high-concentration ethanol into the extraction and separation tank. A heater heats the water in a hot water tank. The second and first solenoid valves are opened, and a third water pump draws water from the hot water tank and injects it into a first heating shell. The hot water in the first heating shell heats the extraction and separation tank, promoting the chlorophyll in the debris to dissolve in the high-concentration ethanol. After a period of dissolution, a fourth water pump draws the ethanol concentrate from the extraction and separation tank into a concentration tank. Then, medium-concentration ethanol is added to the extraction and separation tank to dissolve some of the slightly more polar small molecule impurities in the debris, releasing and extracting the chlorophyll that has fused with them. The fourth water pump then draws the ethanol concentrate from the extraction and separation tank into a concentration tank. Finally, low-concentration ethanol is added to the extraction and separation tank to remove water-soluble impurities such as pectin from the debris, facilitating the extraction of chlorophyll. The fourth water pump then draws the ethanol concentrate from the extraction and separation tank into a concentration tank.
[0015] 2. In this invention, the first and second solenoid valves are closed, while the third and fourth solenoid valves are opened. Hot water from the hot water tank is drawn into the second heating shell by the third water pump. The hot water in the second heating shell heats the solution in the concentration tank in a water bath. The concentration tank is evacuated by a vacuum pump to create a low-pressure state. When the pressure is low, the boiling point of the liquid in the concentration tank decreases, and the hot water in the second heating shell boils and concentrates the liquid in the concentration tank.

[0032] In use, the device is controlled by an external controller. The raw material to be processed is added into the crushing shell 3.
