The utility model adopts countercurrent extraction technology. The grass jelly material is conveyed from one end of a screw conveyor to the other end, while the grass jelly extract moves in the opposite direction to achieve countercurrent extraction of the grass jelly material with high extraction efficiency. Water sieve holes are provided on the blades of the screw conveyor to facilitate the flow of the extract. At the same time, the extract can fully contact the grass jelly material for more complete extraction. A multi-stage extraction device is adopted.

The countercurrent tank (17) is auxiliary limited, the support frame (35) is placed on the top of the second fixed base (44), one end of the second infusion tube (34) is clamped and installed inside the liquid inlet (37), the first cover plate (23) is placed on the top of the first countercurrent tank (14), the first cover plate (23) is limited to the top of the first countercurrent tank (14) by the first anti-slip gasket (24), and the extraction liquid is transported to the inside of the first countercurrent tank (14) through the feeding pipe (25); In the second step, the first servo motor (20) is powered by one set of electric control boxes (45), and the hydraulic cylinder (29) is powered by the other three sets of electric control boxes (45), so as to start the first servo motor (20), drive the first rotating rod (21) to rotate, drive the first stirring blade (22) to rotate, stir and mix the material and the extract placed in the first countercurrent tank (14), and transport the extract to the inside of the second countercurrent tank (15) through the first liquid infusion pipe (26) on the outer wall of the first countercurrent tank (14), and respectively place the three sets of second cover plates (27) in the second countercurrent tank (15), the third countercurrent tank (15), and the fourth countercurrent tank (15). (16) and the top of the fourth counterflow tank (17), the three sets of second cover plates (27) are limited to the tops of the second counterflow tank (15), the third counterflow tank (16) and the fourth counterflow tank (17) by the second anti-slip gasket (28), the hydraulic cylinder (29) is started, the hydraulic push rod (30) is driven to move downward, the first pressing plate (31) is driven to move downward, the damping spring rod (33) is pushed downward, the first pressing plate (31) and the second pressing plate (32) are supported by the damping spring rod (33), the extract is squeezed three times, and the extract is transported through the two sets of first infusion tubes (26); In the third step, the extract in the fourth countercurrent tank (17) is transported to the inside of the filter tank (18) through the second infusion pipe (34), the extract transported by the second infusion pipe (34) is filtered three times through the fixed circular plate (41), the second servo motor (38) is started to drive the second rotating rod (39) to rotate, the extract is auxiliary stirred, and the filtered extract is output through the liquid outlet pipe (36).
