Abstract

The tea physical properties and quality are often influenced by the rolling pressure in the tea production. In this paper, the tea rolling modeling in the barrel rolling machine is established by analyzing the force situation of the tea leaves in the barrel rolling machine. The joint rolling curve synthesis of the pressure and rolling disk speed are formulated as a convex optimization form that can be efficiently solved by existing numerical methods. The rolling process automatic control technology is used to control the pressure and the speed parameters in real time. To make the curly tea leaves, the values of tea crowded force are properly changed by measured the values of the barrel internal pressure and the rolling disk speed. The test results show that: the barrel tea rolling machine which has the adjustable speed limit is 60rads/min; the adjustable pressure limit is 800N and the barrel diameter is 550mm, when the rolling tea weight is between the 500g to 4000g, its the tea breakage rate is less than 10%.
