The contradiction between measurement accuracy and measurement speed has not been resolved in the field of moisture detection; Provide an instrument with a drying method structure for rapid determination of moisture in response to this situation. The starch moisture analyzer adopts the German HBM weighing system for accurate weighing; Circular infrared heating source for rapid drying of samples; During the drying process, the starch moisture analyzer continuously measures and displays the% lost moisture content of the sample in real time. After the drying program is completed, the final measured moisture content value is locked and displayed. Compared with the oven heating method, infrared heating can uniformly and quickly dry the sample at a certain temperature, and the surface of the sample is not easily damaged. Its detection results have good consistency with the oven method, are replaceable, and the detection efficiency is much higher than that of the oven method. Intelligent operation, and the determination of general samples can be completed in just a few minutes, making it a new type of rapid detection instrument.
