Loading characteristics of in-mould steaming process for dark-green brick tea
摘要
Abstract
To further optimize the parameters of the in-mould steaming process for dark-green brick tea,we fit the equivalent load in the suppression process using experimental data and established a model based on the AMESim and MATLAB software platforms.The simulation results indicated that the pressing process of high-quality dark-green brick tea takes 5.5 s,an increase of 1.5 s compared to the unloaded process,with a single cycle time of 116.8 s;in a mould with a structure of infinite number of columns,the maximum and minimum thickness of the finished tea bricks produced in single,double,triple,and quadruple pieces modes is 11.0 and 10.6 mm,respectively.By reducing the pump speed to 40%of the power frequency,the thickness deviation can be controlled within 0.2 mm,while the pressing process increases by 0.5 s.The maximum pressure during the pressing process of high-quality dark-green brick tea reaches 19.5 MPa,and the its pressure drop is faster than that of the old dark-green brick tea.Experimental verification showed that the thickness of the finished dark-green tea bricks is consistent with the simulation results,and the production capacity is slightly lower than the theoretical value.This fast simulation model with easily modifiable parameters effectively shortens the development cycle of the dark-green brick mould and lays a theoretical foundation for the establishment of a dark-green brick tea expert production system.关键词
