Problems solved by technology

None of these studies analyzed the changes in the temperature field during the de-enzyming process of the drum. After the temperature of the tea leaves changes during the de-enzyming process, the stress on the de-enzymed leaves will also change accordingly. These can be further analyzed by simulating the de-enzyming process.

Abstract

According to a discrete element particle model theory, the invention includes selecting a tea particle shape, a contact mechanical model and a contact judgment algorithm, and constructing a gas-solidcoupling equation between the fluid and the tea particles; based on a gas-solid coupling equation, verifying the influence of the roller rotating speed, the number of guide vane plates and the rollerinclination angle of the fixation machine on the porosity of tea particles, the water content of tea, the temperature rise rate and the dehydration rate in the fixation process; analyzing main factorsinfluencing the fixation effect to obtain a tea fixation optimization evaluation standard, and optimally designing the mechanical structure and motion parameters of the fixation machine.

Description

[0001] The invention relates to a method for optimizing the structure of a tea degreening machine device, in particular to a method for optimizing the structure of a tea degreening machine based on the discrete element principle. Background technique [0002] my country is the origin of tea trees, with a long history of tea production and a vast tea area. Green tea is made from suitable new leaves of tea trees without fermentation, and is made through typical processes such as greening, kneading, and drying. The dry tea color and the brewed tea soup and the bottom of the leaves are mainly green. Green tea has the highest output among various teas today, accounting for about 70% of the national tea output. Green tea is not only a large traditional product for my country's tea export, but also a leading product for my country's tea production and consumption. At present, domestic research on green tea processing technology and equipment is relatively backward, so the research o...
