Orthodox Tea Long Tea. Different Grades Is Tgfop, Gfop & Fop For Long Tea. Orthodox tea leaves are heavily rolled either by hand or mechanically on a cylindrical rolling table or a rotor vane. The rolling table consists of a ridged table-top moving in an eccentric manner to a large hopper of tea leaves, of which the leaves are pressed down onto the table-top. The process produces a mixture of whole and broken leaves, and particles which are then sorted, oxidized, and dried. The rotovate consists of an auger pushing withered tea leaves through a vane cylinder which crushes and evenly cuts the leaves.Crush, tear, curl is a production method developed by William McKercher in 1930 which uses machines with contra-rotating rotors with surfaces patterning that cut and tear the leaves producing a product popular for use in tea bags. The rotovate is often used to pre-cut the withered tea prior to the CTC and to create broken orthodox processed black tea
