[0002] A plant beverage refers to a beverage product processed or fermented from plants or plant extracts (except tea and coffee) as raw materials (roots, stems, leaves, flowers, seeds of non-fruit and vegetable plants, or the sap secreted by bamboo or trees themselves, such as grains, edible fungi, edible algae and ferns, cocoa, chrysanthemum, etc.).

[0003] In the prior art, the patent number is CN222821512U, and the name is a spice processing filtration and purification device, which includes a preparation cylinder.

Since the diameter of the vertical rod (31) is smaller than the diameter of the vertical groove (30), the juice flows to the bottom of the lifting block (29) through the vertical groove (30). The piston rod (32) drives the lifting block (29) to descend, so that the lifting block (29) presses down the juice in the squeezing chamber (37) again. The end of the connecting pipe (25) is provided with a filter screen, so that the filtered juice enters the feeding pipe (20) through the connecting pipe (25).
