Description

Technical Field

[0001] This utility model relates to the field of sugar alcohol production technology, and in particular to an automatic refractive index detection device for quality control points. Background Technology

[0002] Refractive index, as an important indicator of the optical properties of materials, is increasingly widely used in chemical analysis, biological detection, food processing, and petrochemical industries. The technology for measuring refractive index has evolved from early manual operations to modern automated equipment, but this process has not been without its challenges. Early methods relied primarily on optical instruments and manual readings. While these methods could provide results to some extent, their accuracy was difficult to guarantee due to limitations imposed by the operator's skill level and subjective judgment. With the introduction of automation technology, refractive index measurement has begun to develop towards automation and intelligence; however, existing automated equipment still has many shortcomings in practical applications.

[0003] Existing refractive index measurement technologies, especially those applied in the production of sugar alcohols, generally suffer from complex operation and low efficiency. For example, in the purification process of sorbitol, the sample needs to be taken first, and then measured manually, approximately once an hour. The requirement is to measure the refractive index of six samples from six tanks within one minute. The operator needs to manually adjust the instrument, add the sample, and read the scale value through the eyepiece. This process is not only time-consuming but also easily affected by factors such as operator fatigue and distraction, resulting in large fluctuations in the measurement results.

[0004] In addition, existing refractive index measurement equipment often requires regular manual cleaning and maintenance. This cleaning method is not only time-consuming, but also increases the complexity of operation and reduces the efficiency of testing.

[0005] Given the existing technology, the key technical issues that this solution aims to address are mainly focused on improving the detection efficiency, accuracy, and stability of refractive index measurement. Utility Model Content
