With the continuous development of our country economy, people's living standard and quality enhances unceasingly, dietary changes, such as rice and flour bulk varieties has can't satisfy people's consumption demand, people of green food, health food, rarity, more and more customers. Coarse grains, with their own nutrition, health care and green features, will be recognized by more and more people, which is of great significance to the development of coarse grains. So there is a variety of food color selection.
It can be widely used in agriculture, food industry, tea industry, industry, etc., to improve the quality of selected materials, increase its added value, and ensure the safety of consumption and use. The wide spread and use of omni-grain color selecting machine has replaced the large and tedious manual screening work, which has greatly accelerated the screening speed and efficiency, which is better than the artificial screening effect. After the selection of grain color selection of grain, after removing impurities, the value added. It is the new generation of food processing, agricultural machinery artificial intelligence color selection equipment, is the farmer screening and the good helper of getting rich.
The color selection machine is the mechanical equipment of the high technology photoelectric integration which is automatically divided into the different color particles in the granule materials by using the optical equipment. Taihe working principle of the photoelectric color separator is selected objects from the top of the machine into the hopper into the machine, through the vibration of the vibration device materials uniform will be assigned to the object selected materials along the material trough manger speed down to reach the separation chamber.
In the separation chamber CCD sensor for material color and shape information. The CCD camera sends the information to the FPGA + DSP architecture processor, processor through efficient image processing algorithm to distinguish between normal material defects in the material, and then by controlling the high frequency electromagnetic valve gear will be defective material into the cavity by waste material, the normal finished materials continue to fall into the hopper of cavity, so as to achieve the aim of eliminating defective material.
