1 Scope

Part 8 of China's national standard for compressed tea, covering mi zhuan or rice brick tea. Rice brick is the finest-textured member of the compressed tea family and the one made from the smallest material: its raw tea is sieved black tea, the fine particles and fragments that are separated out in grading other teas, which is what gives the brick its dense, smooth, almost uniform appearance and its name. It is pressed harder than the coarse bricks and carries a moulded design on its face - the traditional bricks were pressed with characters and patterns - which the fine material takes cleanly where a stemmy tea would not. Its production is correspondingly short: sieving, steaming, pressing and drying, without the extended piling and fermentation that the dark teas require, since the raw material is already finished black tea. This part specifies the requirements, test methods, inspection rules, marking, labelling, packaging, transport, storage and shelf life for rice brick tea.

GB/T 9833 provisions of this part of the meter brick requirements, test methods, inspection rules, marking, labeling, packaging, transportation, storage and security Shelf. This section applies to black tea as raw material, rice brick sieved, vapor pressure developing type, drying, product packaging and other processes made.
