In-line ice cream quality monitoring using multi-modal imaging and polarization
A cutting-edge solution for monitoring ice cream quality using RGB and NIR imaging combined with partial Mueller-matrix polarimetry, enabling real-time assessment of pigment distribution, air void fraction, and crystalization properties.
Overview
The in-line ice cream quality monitoring system is an innovative solution designed to enhance the manufacturing process by providing real-time, non-contact assessments of key quality metrics. By integrating RGB and near-infrared (NIR) imaging with partial Mueller-matrix polarimetry, this technology offers precise evaluations of an ice cream's pigment distribution, air void fraction, and crystallization properties. This ensures consistency in product texture and color, crucial for maintaining brand standards and consumer satisfaction.
Technical specifications
Key features:
