The invention relates to the technical field of feed quality control, in particular to an intelligent feed processing quality control method and system. According to the method, the operation parameters and the environment temperature and humidity of the production equipment are acquired in real time, and the environment and equipment state parameter set is established, so that the influence factors of the production conditions are quantified, and an accurate basis is provided for parameter adjustment of the subsequent processing flow. In the production process, the adaptive processing flow threshold value is calculated based on the operation stability of equipment and the change trend of raw material components, and unstable product quality caused by raw material fluctuation or equipment state change is avoided. And whether key indexes in the production process are in an adaptive range or not is dynamically judged by combining the change conditions of the steam absorption rate and the granulation pressure, so that the processing flow control is finer. For trend deviation possibly occurring in the production process, the stability of the production process is analyzed by analyzing the equipment load level, the energy consumption change synchronism and the abnormal trend of processing flow parameters.
