The emergence of tea color sorting machines has solved the labor-consuming and time-consuming problem of picking and removing stems in tea processing. The picking operation has become the bottleneck link of quality and cost control in tea refining. The number of mechanical picking of fresh tea leaves has increased, and the amount of picking stems in tea processing has also increased.

The working principle of tea color sorter

The tea color sorter machine toelectric technology to remove abnormally colored materials. It analyzes the appearance and color of the tea material surface through the photoelectric system to distinguish tea, stems and non-tea inclusions. It can solve the problems that cannot be solved by conventional screening, winnowing and sorting equipment. The best tea stem separation effect achieved. There are several long and narrow passages in the sorting chamber of the color sorter, and a highly stable light source is installed at the exit of the passage. When the tea material enters the sorting area evenly through the chute channel through the vibrating feeding system, before the material passes through the detection area, it relies on gravity and The falling speed causes each tea leaf to be arranged in a straight line and fall into the photoelectric detection chamber one by one. When the material passes through, check it from both sides to determine the abnormal color. The photoelectric sensor measures the amount of reflected light and projected light, compares it with the amount of reflected light from the reference color plate, and amplifies the difference signal. When the signal is greater than the predetermined value , drive the injection system to blow out the different-colored materials with compressed air. The tea Ccd color machine ses a new generation of digital signal processor (DSP) to replace the traditional industrial computer, and uses fuzzy logic algorithm and support vector machine (SVM) algorithm to automatically adjust the background plate angle and feeding speed, truly realizing color selection. Fully automatic control of machine selection allows the machine’s performance to automatically reach its optimal state during operation.
