Photoelectric color separator is used for bulk material quality detection and classification of a non-destructive sorting equipment, in food, food, pigment chemical industry has a wide range of applications, It has remarkable sorting effect on difficult recycled plastic sheets, plastic particles, corn, all kinds of beans, all kinds of rice, ore, pepper, pepper, garlic rice, melon seeds, raisins, seeds, Traditional Chinese medicine, sea rice, shrimp skin, clove fish, and special materials.
According to the difference of optical properties of materials, the use of photoelectric detection technology will automatically sort out the heterochromatic particles in granular materials. Photoelectric color separator is used for bulk material quality detection and classification of a non-destructive sorting equipment, in food, food, pigment chemical industry has a wide range of applications. It can separate plastic, glass, metal, same color rod and other malignant impurities in grain, reaching the international leading level. As a typical opto-mechatronics system, color sorter involves the innovation and application of opto-mechatronics software in various fields, and its upgrading speed is very fast. It is a typical innovative scientific and technological product. Color sorter consists of four systems, feed = transmission = detection = sorting! Let's really know the performance of the color picker:
1. Limited capacity of color selecting machine
(1) The color separator is not a classifier, which mainly completes the removal of a few defective materials in most normal materials; The ability to classify materials with similar proportions is limited and cannot be completed at a time like selecting rice.
(2) color separator is mainly through the surface color of the object color selection, normal materials and defective materials must have a certain color difference; The smaller the color difference, the more difficult the color selection, the worse the performance index.
(3) the capacity of the color separator is directly related to the quality of the raw grain. The impurity content of 2% and 20% has a great influence on the performance index of the color separator.
(4) There is no 100% elimination rate.
2. Objectively evaluate the relationship between yield, color selection effect and take-out ratio
The three indexes have mutual influence and restriction. After the normal debugging of the machine, improve the sensitivity, the better the color selection effect, the greater the ratio will be brought out; The yield also directly affects the effect of color selection and take out ratio. In the actual commissioning should be based on customer requirements and raw grain conditions to compromise, in order to achieve the maximum satisfaction of customers. A few principles should be grasped:
(1) In the case that the color selection effect can meet the requirements, the lower the sensitivity, the better.
(2) excessively improve the sensitivity, the improvement of sensitivity will lead to the electromagnetic valve blowing too much into the protection state, may make the color selection effect worse.
(3) It is necessary to ensure that the materials returned to the raw grain are similar to the raw grain.
(4) Pay attention to communicate with customers and understand their requirements.
3. Correct understanding of color selection of non-rice materials
Coarse grains vary widely and there is no certain standard. Therefore, customers should be advised to provide raw grains to the factory for testing and sealing samples.
