Problems solved by technology

[0003] 1. The material will generate heat during the crushing and homogenization process, which will cause the material to heat up and lose water
The temperature rise of the material causes the accuracy of the near-infrared detection results to decrease, and the loss of water means that the measured moisture result can only represent the measured moisture value of the material after homogenization, but cannot reflect the real moisture value of the material before pretreatment, thereby affecting Detection results of protein components of key closed-loop control indicators
[0004] 2. The lost water vapor condenses in the measurement channel and mixes with the material powder to produce paste, which adheres to the inner wall of the pretreatment equipment, which is difficult to clean and easily blocks the pipeline, causing equipment failure

The near-infrared analysis system comprises a near-infrared analysis instrument, smashing equipment, temperaturecontrol equipment, stirring equipment, a first valve, a detection chamber and a second valve, wherein the smashing equipment is used for smashing the solid material, and conveying the solid materialto the stirring equipment; the temperature control equipment is used for temperature T in the smashing equipment to prevent moisture from condensing; the stirring equipment is used for mixing a powdery material conveyed by the smashing equipment; the first valve is arranged at the outlet of the stirring equipment; the detection chamber is used for containing the powdery material conveyed by the stirring equipment, and the near-infrared analysis instrument is used for detecting parameters of the powdery material in the detection chamber; the parameters comprise dry basis protein B1; the secondvalve is arranged at the outlet of the detection chamber. The near-infrared analysis system has the advantages of accurate detection and the like.

Description

Technical field [0001] The invention relates to solid material analysis, and particularly relates to a near-infrared analysis system and method for object materials. Background technique [0002] In the intelligent automated production process of food and feed, when the online near-infrared system measures uneven solid materials such as food and feed, a pretreatment system is generally installed to crush and homogenize the material to be tested to obtain a stable The detection result is conducive to closed-loop control. The system has the following problems: [0003] 1. The material will generate heat during the crushing and homogenization process, which will cause the material to heat up and lose water. The heating of the material causes the accuracy of the near-infrared detection result to decrease, and the loss of water dispersion means that the measured moisture result can only represent the moisture value of the measured material after homogenization, and cannot reflect the ...
