Online detection method for oil stain pollution of materials in tobacco primary processing

The invention belongs to the technical field of tobacco manufacturing and provides an online detection method for the oil stain pollution of materials in tobacco primary processing. According to the method, oil stain detection is carried out on to-be-processed raw materials, processed raw materials and to-be-rolled raw materials; a detection result is calculated through a near infrared spectrum and a plurality of calculation means; model correction and result recording are employed; and therefore, the accuracy and full utilization of the result can be ensured. The quality of products can be effectively improved; oil-stained tobacco is controlled in a raw material stage; and a timely and reasonable basis is provided for the improvement of a production process through the effective storage of the result. 本发明属于烟草制造技术领域，具体涉及一种用于制丝物料油渍污染在线检测方法，通过对原料加工前、原料加工后以及卷包前的原料进行油渍检测，并采用近红外光谱结合多种计算手段进行检测结果的计算，并结合模型修正和结果记录，保证的结果的准确和充分利用。有效提升了产品质量，同时将油渍烟控制在原料阶段，并通过结果的有效保存为生产工艺改进提供了及时合理的依据。
