工厂杂质处理流程：从仓库到锅炉

The factory has an impurity storage warehouse. Impurities removed from the raw soybeans by the second and third lines will be directly transported from the production line to the warehouse. When the warehouse is full, the impurities will be transported to the boiler room and mixed with coal to be burned. The amount of impurities will be counted every time the warehouse is cleaned.
