Introduction

Optical sorting machines have revolutionized the way industries sort and process materials such as food, plastics, and metals. These machines rely on advanced camera and sensor technologies to rapidly identify and separate objects based on color, size, shape, and other characteristics. In this report, we will explore the role of cameras and sensors in modern optical sorting machines, as well as the companies leading the way in this industry.

Camera Technologies

High-Resolution Cameras

One of the key components of optical sorting machines is high-resolution cameras that capture detailed images of the materials being sorted. These cameras can detect even the smallest defects or impurities, ensuring that only the highest quality products make it through the sorting process. Companies like Key Technology and Bühler Group are known for their cutting-edge camera technologies that enhance the accuracy and efficiency of optical sorting machines.

Hyperspectral Imaging

Hyperspectral imaging is another advanced camera technology used in optical sorting machines. This technique captures images across a wide spectrum of wavelengths, allowing for more precise identification of materials based on their chemical composition. By analyzing the unique spectral signatures of different objects, hyperspectral cameras can differentiate between materials that may appear similar to the naked eye. Companies like TOMRA are at the forefront of incorporating hyperspectral imaging into their sorting machines to achieve unparalleled levels of accuracy.

Sensor Technologies

RGB Sensors

RGB sensors are commonly used in optical sorting machines to detect differences in color and intensity. These sensors work in conjunction with cameras to provide additional data points for sorting materials based on their visual characteristics. Companies like Satake Corporation and Allgaier Werke GmbH are known for their innovative use of RGB sensors in their sorting machines, allowing for precise color-based sorting in industries such as food processing and recycling.

Laser Sensors

Laser sensors play a crucial role in measuring the size and shape of objects passing through optical sorting machines. By emitting a laser beam and analyzing the reflections, these sensors can accurately determine the dimensions of materials in real-time. Companies like Cimbria and Binder+Co are leading the way in integrating laser sensors into their sorting machines, enabling precise sorting based on size criteria.
