Food Sorting Machine Introduction

Chapter 1: How to sort food by machine

With the progress of society and the development of science and technology, robots have begun to enter the production process and daily life. Various types of sorting machines are playing an increasingly important role in specific working environments. Common solid sorting equipment can perform sorting according to the different physical and chemical properties of the product. Such machines are often fully automatic sorting equipment. You can choose different sorting machines according to your needs.

Chapter 2: How food sorting machine works

Color sorting machine is mainly composed of a feeding system, an optical detection system, a signal processing system and a separation execution system. A device that automatically sorts out heterogeneous particles in granular materials based on the differences in optical characteristics of the materials. The selected materials enter the machine from the hopper on the top, and the selected materials are transmitted along the channel through the vibration of the vibrator device. Enter the observation area in the sorting room and pass between the sensor and the background board. Under the action of the light source, according to the intensity of the light and the color change, the system generates an output signal to drive the solenoid valve to blow out different-colored particles to the waste hopper, and the good selected materials continue to fall to the finished hopper, thereby achieving the purpose of sort.

Chapter 3: Installation and commissioning of food sorting machine

The color sorting machine must be installed at an overall level. It should be installed in a place without vibration to avoid vibration and reduce the accuracy of color selection. Do not install the color sorter in a place where it can be directly exposed to sunlight, as it will affect its photoelectric system to collect signals. Do not install the color sorter in a humid, hot, dusty place. If possible, install it in a separate and isolated room, and install air conditioning maintenance. As for the color sorter commissioning, senior engineers generally need to work on site, because work experience and professional knowledge are required.

Chapter 4: Repair and maintenance of food sorting machine

Open the upper and lower sorting boxes, and clean the inside of the upper glass, the surface of the lower light source, the lens of the lower camera, the double-sided double-sided lower camera reflector and its lens, and clean the high-precision parts of the camera. To be careful and slight, consider using a cotton ball alcohol to wipe off the dust, and finally close the sorting box cover tightly. Check whether there are screws inside or outside the machine, and the terminals are loose, such as the screws near the vibrator and the terminals in the sorting box. For greaseable bearings, consider adding butter. For the wearing parts, if the small belt of the cleaning brush is worn out, you need to consider whether to replace it. Test each valve. If abnormal, repair or consider replacing the solenoid valve. Depending on the conditions of use, the use time of the filter element varies, and it is generally replaced once a year.

Chapter 5: Technical parameters of food sorting machine

RGB full color tri-chromatic CCD image acquisition system. High camera resolution 5340 pixel identifying tiny defects up to 0.01mm2. High quality ejector with 5-10 billion ejections life low air consumption. Most unique intelligent LED with cold shadowless light source and super long life span, high lighting efficiency.

International high-end full-color line scan technology, DSP+FPGA processing the international forefront of technology, combining a variety of colors and shapes model complex algorithms, to provide "color selection shape selected" function for different materials.

Chapter 6: Application of food sorting machine

The automatic sorting machine can directly replace the manual sorting work to achieve the purpose of improving production efficiency, improving accuracy and reducing labor, and reducing enterprise operating costs and labor costs. The automatic sorting machine can select product combinations with different weights, sizes, colors and other characteristics to select the working line, eliminating the financial and time of manual operation, and more accurate and precise. Widely used in food sorting, fruit sorting, food sorting, ore sorting, garbage sorting and other industrial product sorting industries.

Chapter 7: Factors for evaluating food sorting machine

The main purpose of the color sorter is to select high-quality materials. Therefore, the net selection rate is one of the main technical indicators for evaluating the performance of the color sorter. The rejection rate refers to the ratio of the heterogeneous particles removed from the material to the heterogeneous particles contained in the product before color selection after the material is sorted. The higher the rejection rate, the cleaner the selection. In the case of a certain amount of processing, the higher the selection rate of the color sorter, the higher the sensitivity of the color sorter, instead of blindly increasing the sensitivity to complete it. Of course, stable machines and timely after-sales service are also key factors in evaluating machines.

Chapter 8: Technical development trend of food sorting machine

The color sorting machine evolved from single-sided to double-sided, and the sensor was upgraded from CMOS to CCD. Sorter technology is constantly improving. China has mastered the core technology of producing color sorters, and its products have gradually occupied more than 70% of the global market share. As industry companies continue to increase the amount and proportion of R & D investment in color sorting machinery, and promote technological innovation capabilities, product performance gradually catches up to and even exceeds similar foreign products. In the future, the technology will tend to be large-volume, intelligent, high-precision, and multi-purpose Innovative technology.
