Small, wet and sticky materials in rice threshed mixtures could be easily to adhere to the surface of metal jitter plate in cleaning device. A method to reduce the adhesion of wet sticky rice materials and metal jitter plate by interface heating was proposed. The Galvanized plate and stainless steel plate were used as test parts. The small wet sticky rice material was processed by crusher. Firstly, the model of adhesion interface between wet sticky rice material and metal jitter plate was constructed. The capillarity of water film was an important reason for the formation of adhesion interface. The anti-adhesion mechanism of interface heating of metal jitter plates was revealed. Secondly, loading and heating anti-adhesion test was carried out with electronic universal testing machine. The anti-adhesion rate curve models of Galvanized plate and stainless steel plate were obtained. The results showed that wet sticky rice materials were effectively inhibited to adhere to the surface of test parts through interface heating. The anti-adhesion rate of two kinds of metal jitter plates were respectively 61.81% and 61.33% when the temperature was 50℃. Then, vibrating and heating anti-adhesion test was carried out by using linear vibration test bed. The results showed that anti-adhesion rate was influenced by vibration strength of metal jitter plates. When the temperature of metal jitter plate was 40℃, the vibration frequency was 6Hz, and the amplitude was 40mm, the anti-adhesion rate exceeded 65%, which met the actual operation requirements. Finally, the verification test showed that the application of hot flow heating was an effective interface heating way to reduce adhesion between wet sticky rice materials and jitter plate in actual cleaning process.
