Abstract
The rotary Lu'an Guapian baker was designed, according to the Lu'an Guapian traditional baking process. Far-infrared radiation heating unit was used in the tea baker, and an intermittent heating mode was used at the same time. The rotary table was droved by 0.5 kW AC motor, with the electric heating unit power 36 kW, heating and stopping time form 3 s to 5 s. The intermittent heating control system and the strong anti-jamming infrared light emitting and receiving circuit were designed in the study. Double 555 multivibrator is used as infrared emission circuit, and UPC1373 and audio PLL IC LM567 were used as a frequency selective receiver. The Lu'an Guapian baking experiment was done with the prototype. The results showed that the control of machine baking time and temperature was more precise, compared with artificial baking. This machine scores closed to the traditional manual baking tea when the control temperature was 68 ℃, and the machine baking score was higher than the traditional artificial baking when the control temperature was 73, 82 and 87 ℃ respectively.
