This article introduced the background of the revision of the local standard"Longjing Tea Processing Technical Regulations"(DB33/T 239-2023)in Zhejiang Province,and interpreted the similarities and differences in content between the new and old versions of the standard.In particular,the new version of the standard refined the mechanical processing process flow based on the grade of fresh leaves,optimized and adjusted some mechanism processes and parameters,and added a pattern diagram.In response to the current production status of Longjing tea,it was proposed to choose a suitable process flow based on the grade of fresh leaves.The fresh leaf spreading should take into account the spreading time,water loss rate,and moisture content,as well as measures and suggestions such as grasping the supporting technology of mechanical processing.
