Is widely applied in many fields of grain color separator
Color machine widely used in many fields, such as the food industry of rice, grains (beans) and grade of tea class for color choose, some industrial chemical industry (plastic sheet, plastic pellets, salt, etc.) can also be used to. Machine material images taken by microcomputer, intelligent sorting according to the pictures.
Application of color machine in our country, first of all in the rice industry rapidly expand, then in seeds, oil, fruit, etc. Recently, our country take the lead in successfully chose color technology is applied to the larger flour processing industry, enable it to produce a higher level and quality of a material more pure high-grade food special flour, excellent market reaction. Due to the effect of color separator is valued by many people of insight to color machine market in recent years has been bullish, producers have a good profit, and the color machine market is more and more big.
Color separator type sensor is mainly divided into the traditional sensor (photocell, silicon photocell, etc.) and CCD (or MOS) sensor type two kinds. Sensor is composed of optical system and photoelectric conversion device, its role is to make the different color particles accurately identify from the high-speed movement of logistics, through configuration of other injection to clear from a rapid response. Early color machine adopts photocell, photoelectric diode and the silicon photocell to detect the light signal, its the biggest advantage is low cost, production, easy debugging and production, the subsequent signal processing circuit is simple, the matching of the optical system using simple electric eye, is composed of two pieces of simple lens, do not need to adjust, the cost is low. Its defect is low resolution, with ailment of particles and light impurities recognition ability is poor. Because this kind of color separator corresponding to each slide only USES a sensor, it was observed that the ramp within the scope of the general optical signals, and can't separate to shed at the same time a slide several rice or wheat color. A grain of rice, for example, there are both a black and a white spot on, so its signal is a normal not black not white m signals, and light yellow disease spot meters signal can be other colors brighter grain signal average by identification. At the same time, its optical system imaging quality is poor, the light path can't adjust, poor consistency, a direct impact on the performance of color separator, the limit color machine production capacity and color choice.
