Abstract: During operation of traditional tea rolling machines, tea leaves continuously rolling in rolling barrel, causing pressure on tea to fluctuate greatly and violently, making it difficult to quantify and accurately control pressure．In response to above problems, a real-time dynamic adjustment control method for rolling pressure was proposed, and hardware, algorithm, and program of control system were elaborated in detail．The system could quantify pressure value．Dynamic adjustment, real-time performance, and precise control of rolling pressure control have been ensured．Experiments have shown that tea rolling machine equipped with this system met industry standard requirements in terms of sliver formation rate, broken tea rate, and production efficiency．
