Product Introduction
1. Product Introduction of Near-Infrared Moisture Meter for Flour Production Line
The near-infrared online moisture meter is aNon-contact, non-destructive, continuous real-time moisture content detection equipment, based on the principle of near-infrared spectral absorption-diffuse reflectance of water molecules. The probe is installed above belt conveyors, chutes, or dryer discharge outlets. No sampling or material contact is required, with millisecond-level real-time moisture reading. It can directly interface with PLC and DCS control systems to achieve closed-loop automatic control of drying and humidification processes, eliminating the lag of offline laboratory analysis, stabilizing product moisture content, and reducing drying energy consumption. It is a dedicated instrument for intelligent moisture management in industrial production lines.
The entire equipment consists ofDetection probe + control host + signal cableComposed of three parts; supports multi-material curve storage, temperature and dust compensation, adapting to harsh workshop conditions such as dust, high temperature, and high humidity, with 24-hour continuous operation.
Core principle: Water molecules absorb specific bands of near-infrared light. The instrument emits a light source to irradiate the material surface, receives reflected light signals, and calculates the material moisture content value through built-in algorithm models. Detection processNo damage to materials, no consumables.
