The invention discloses a 
system and a method for producing chili oil. The 
system comprises a stir-frying device, an airing device, a smashing device, a frying device, an 
ultrasonic device, a rectifying device, an extracting device and a separating device. The method includes stir-frying, airing, smashing, frying, ultrasonic treatment, extracting, separating and refining. The 
system and the method have the advantages that various 
processing devices are effectively connected with one another, accordingly, the chili 
oil can be basically automatically produced, large quantities of labor and materials can be reduced, and the production cost can be saved to a great extent; stir-fried chili is aired, accordingly, the uniform content of 
moisture in the chili can be advantageously controlled, and the oil yield of the chili can be increased; 
chili powder is subjected to ultrasonic treatment at first, accordingly, the extraction time of the 
chili powder can be shortened to a great extent, release of oil in cells can be enhanced under vibration effects of ultrasonic 
waves, a large quantity of 
oil can be extracted in a promoted manner, and the oil yield of the chili can be increased; peculiar smell in the chili 
oil can be effectively removed by means of rectifying treatment, and accordingly the quality and 
aroma of the chili oil can be improved.
