Drying of andrographis paniculata with hot air controlled with artificial intelligence

This article presents the development of drying Andrographis paniculata with hot air controlled by artificial intelligence system together with infrared rays. The tools used in the research are Andrographis paniculata drying cabinet with hot air controlled by artificial intelligence system together with infrared rays. The part consists of an oven with a width of 1204 millimeters and a length of 380 millimeters. A 65-watt blower fan serves to blow air to move heat evenly into the dryer. The source of heat release uses a heating coil, Fin Heater/fin heater. Voltage size 220 V 1,000 W, length 450 mm, metal weave size 11 mm, fin size 31 mm. Heat with a thermocouple was checked to compare with the temperature set. In the event that the temperature in the Andrographis paniculata dryer has not decreased, the thermal camera will turn on the ventilation fan to carry the heat outside. and ordered to reduce the temperature of the heater. The measured temperature data will be saved to the Raspberry Pi server. Research found that the machine can dry Andrographis paniculata according to the machine's operating conditions. And can dry Andrographis paniculata at a temperature of 40 °C according to the value specified in drying. The humidity before drying was 100 % and after drying – 0.73 %. The weight before drying was – 30g and after drying – 8.1g. The drying rate was 1.37 and the average temperature – 60 °C according to the value specified in drying. Moisture before drying was 100 % and after drying – 0.79 %. Weight before drying was 60g and after drying – 12.6g. Drying rate was 1.27. The system also uses a low heat source with a power of 1 kW. Electrical voltage – 220 V
