Tea as a special industry in the food industry, and was a livelihood of the people of the economy, and the tea and T has a strong seasonal crops, high labor intensity, low efficiency, to take up farming more problems, these problems restrict the further development of tea industry.
Rely on scientific and technological progress, therefore, to strengthen the research and development of tea production machinery, realize the mechanization of tea production, tea from extensive to intensive changes, not only is to improve the tea quality, the key to modernize the tea, but also to improve productivity, save labor and reduce the labor intensity, improve the market competitiveness of China's tea industry, promote the rural construction, agricultural efficiency and farmers' income and promoting the healthy development of tea industry.
Especially in the current shortage of rural labor resources in China, it is not only significant but also urgent to develop the mechanization of tea production. "To do a good job, must first sharpen his", in order to realize mechanization of tea, the first thing to strengthen and perfect the tea machinery standardization construction, change the tea machinery are of variable quality, science and technology content is low, low heat energy utilization, a series of problems. This is the requirement of improving the technological content of tea processing machinery, food sanitation and safety, and establishing intensive society.
In the process of tea processing, it is a time-consuming and critical process to pick up the stems, which is the bottleneck of quality and cost control in the refined tea. Because of mechanical properties, such conventional equipment as terraced and static sorting machines, the picking effect is not ideal. If the black tea is picked and collected by multiple machines, hand picking is still needed, and the cost of hand-picking tea is 10% to 15% of the refined cost of black tea.
In recent years, the quality of artificial plucking of tea leaves has decreased and the number of mechanical tea picking has increased, and the number of picking stalks has increased in the processing of tea leaves, and the industry has been looking forward to the technological breakthrough of tea picking equipment. Tea color separator technology refers to the use of special recognition to capture material surface elements like signals, collecting material light transmittance and other components of information, and use the PLC control and the CPU processing, realize the photoelectric signal exchange, and compared with standard signal analysis of the quality of the material out, using compressed air to the inferior material to eliminate set light, electricity, gas, machine in one high-tech integrated technology, color optional equipment is now widely used in agriculture, food industry, GongKuangYe etc.
