The present invention relates to a method for processing tea tree product, in particularly, a method for processing tea flower. The process comprises of the following steps: picking, dehydrating, steaming, drying, quick-freezing and pulverizing of the tea flowers. The picking step is preferably carried out in the time interval beginning from 2 - 3 days before the pollination of the tea flower to 2 - 3 days after the pollination of the tea flower. Hollow baskets made of bamboo or plastics are used to accommodate the picked tea flowers during the picking and the said tea flowers must be immediately graded and spread. In the dehydrating step, the said tea flowers should be spread at a thickness of 2 - 5 cm on bamboo mat or cement floor and should be gently turned over once every 1 hour. The time of dehydrating for the spread fresh flowers does not exceed 10 hours and the most preferred spreading time is 6 hours. Having been dehydrated, the tea flowers are steamed. A steamer for tea preparation is used directly and the temperature heating the flowers is controlled in a range of 80 - 100 DEG C; The drying step is carried out in several times and most preferably in 3 - 4 times. The temperature of drying is controlled in a range of 60 - 180 DEG C. The thickness of the flower on the baking plate of the dryer is in the range of 2 - 3 cm. After every drying, the tea flowers are taken out of the dryer and spread until cool. The time for spreading cool should be getting longer and longer each time. In the quick-freezing step, the tea flowers are quick-frozen at -20 DEG C to -40 DEG C for 20 minutes. In the pulverizing step, the quick-frozen flowers are taken out of the freezer and immediately put into pulverizer to be pulverized. The whole production process is conducted in a natural way and no chemical reaction or chemical extraction is involved. Therefore natural nutrients and different kinds of effective ingredients of the tea flowers could be preserved to a maximum degree.
