The invention discloses a tobacco leaf temperature anomaly prevention method for leaf feeders. The method includes: 1, acquiring data by a PLC (programmable logic controller); 2, comparing acquired steam pressure to a process requirement; if the steam pressure does not reaches the process requirement, and sending out an alarm message; 3, comparing acquired adjusting steam flow to a theoretical flow; if the steam flow is lower than the standard flow, sending out an alarm message; 4, after one batch of production, counting average opening of adjusting valves; comparing the average opening to an ideal area; if opening distribution exceeds the ideal area, and sending out an alarm message; 5, calculating a total score; if deduction exceeds a set score; sending out an alarm message. The method has the advantages that the status of a temperature control system is monitored in real time, the whole temperature control system is assessed by means of feature curves of key parts and a health assessment ...
