PROBLEM TO BE SOLVED: To perform both inactivation treatment of oxidase and caffeine reduction treatment on fresh tea leaves while suppressing equipment cost, and even if the amount of hot water is reduced to reduce operating cost. Provided is a tea leaf processing apparatus capable of reducing a large amount of caffeine from tea leaves. SOLUTION: In the tea leaf processing apparatus 1 of the present invention, a supply port 5 for a fresh tea leaf T, a supply port 6 for steam V, and a supply port 7 for hot water H are provided on one end side, and the fresh tea leaf T, A pipe body 2 having a discharge port 8 for steam V and hot water H at the other end, and a stirring means 3 for stirring fresh tea leaves T, steam V, and hot water H passing through the pipe body 2. The lower end A of the discharge port 8 can be positioned above the inner lower end B of one end of the tubular body 2, or the lower end A of the discharge port 8 is the same as the inner lower end B of one end of the tubular body 2. It is possible to position it at the height of. [Selection diagram] Fig. 2
