Sorting in Food Industry

Laser Technologies for Sorting in Food Production

Laser technology for sorting enables efficient quality control of optimized industrial processes. Its use in the food and beverage industry is widely spread in classifying fruits, vegetables and nuts on the basis of structural or color defects.

Monocrom laser sources come with various optics options and patterns projection to ensure the optimal performace and high accuracy. Applications include in-line detection or monitoring of target parameters such as dimensions, color, size at high speeds, where the targets are moving fast with a wide range of colors and levels of background ambient light. Wavelengths from 375 nm to 1550 nm  in a range of power between 1 mW and some watts.

  • Sorting in free fall
  • Quality control
  • Classification
