The tea color selection machine analyzes the appearance of the surface of the tea material through the photoelectric system
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.
Color choose 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 the 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.
Tea color separator using photoelectric technology dedicated to eliminate different color material, through the photoelectric system analysis on the surface of the tea material appearance color, to distinguish, inclusions and the tea tea, can solve the routine use of screening and winnowing and picking equipment cannot be achieved by the tea stalk separation effect. Don't indoor color choose pause several narrow channel, the channel exit is equipped with high stability of light source, when tea material via vibration feeding system evenly through the chute channel into the area, material through the detection area, before falling by gravity and the speed of each tea in a straight line pattern, falling into a photoelectric measure in turn.
Each chute has 2 high resolution camera, plus data processing hardware, from either side of the check, when material through determining chromaticity, photoelectric sensor measured the amount of light reflection and projection, and compared with the amount of reflected light reference color plate, its differential signal amplification processing, when the signal is greater than the predetermined value, drive injection system at the ends of the tank nozzle (material) with compressed air to blow out the different color material.
Tea color separator used a new generation of digital signal processor (DSP) to replace the traditional industrial control, and USES the fuzzy logic algorithm and support vector machine (SVM) algorithm, the background plate Angle and feed speed automatic adjustment, achieve the automatic control of the color machine, the performance of the machine automatically at work at the same time to achieve the optimal state.
