Abstract
A method and system for extracting fluids from plant parts is provided. Plant parts are placed into a filter bag that is placed within a fluid impermeable holder, which is generally a non-stick holder such as wax paper or parchment. The fluid impermeable holder is placed into a press that is operable at an elevated temperature. The press applies pressure at a predetermined temperature for a predetermined time to the fluid impermeable holder and filter bag to compress the plant parts and squeeze or extrude the fluid from the plant parts. After a predetermined time, the press is opened and the fluid impermeable holder is removed. The filter bag, with residual plant parts, is removed from the fluid impermeable holder. The fluid impermeable holder is manipulated to collect the fluids, which manipulation may include freezing the fluids and peeling the fluids from the inner surface of the bag.
