Abstract
The technology of processing longan powder using a drum dryer was studied. Effect of the excipient in addition, roller rotating speed, roller temperatuar on the technology was analyzed with response surface methodology, and film foeming ability of drum dryer were taken as response values. For design of process requirement, optimum conditions were as follows:excipie addition was 20%, roller temperatuar was 137℃, roller rotating speed was 3.0r/min, film foeming ability was 96.39%.
