However, the device applies force on both sides to allow the upper pressure plate to move downward, so that the upper pressure plate can pressurize the raw materials in the filter layer to achieve the purpose of filtering. When the upper pressure plate is applied on both sides, there is no thrust in the middle of the upper pressure plate.
