Chen Zongmao of researcher of institute of tea of academy of sciences of agriculture of academician of Chinese Academy of Engineering, China introduces, since putting forward cleanness to change the concept that tea produces 2002 oneself, tea produces an industry to obtain progress in this respect nowadays, many provinces yield tea already built a batch of treatment businesses that accord with cleanness to change a requirement, these enterprises already were close to or achieve international advanced level. But from tea manufacturing whole journey looks, the cleanness of whole journey changes management to still remain to perfect.
Chen Zongmao points out, change from the cleanness of tea garden environment in light of, the choice of tea garden should consider the segregation of tea garden and factory, mining area, residential area, other farm. The soil that should choose the ground to drafting, air, fountainhead undertakes detecting, the contaminative degree of the pesticide in mastering its, heavy metal and other contaminant, development should consider around potential pollution source more when organic tea garden. The cleanness that cultivates from tea is changed in light of, be pesticide remain and the control that heavy metal pollutes and soil mainly is improved. Should reasonable choose pesticide, want to understand the origin that different area lead pollutes at the same time, specific aim ground adopts measure to reduce pollution.
Change from the cleanness that machines a process in light of, the construction of tea factory wants the design of referenced food factory, want to have segregation room, the requirement that manufacturing staff should machine by food factory undertakes sanitation defends. Tea treatment is used as far as possible turn water product line continuously, come true not be born production, reduce the pollution that artificial operation brings. Converting manufacturing plant continuously without conditional implementation, can pass among join equipment development. Should convert in addition clean fuel, use the clean fuel such as liquefied petroleum gas, derv, report to do the sources of energy.
