Abstract: The design and manufacture of roasted coffee beans storage system have been carried out, which is used to
reduce the deterioration of roasted coffee beans quality. The method of a coffee bean storage device using a
Peltier plate as a cooler and a DHT11 sensor for temperature readers is then controlled by Arduino Uno. The
results of the manufacture of the tool found that the device can store roasted coffee beans with a reference
temperature of 23 ? and humidity of 40% for a certain length of time. The tool can reach a set point with a
coffee load mass of 0 Kg, 1 Kg, 2 Kg, and 3 Kg at different times for no-load time to get a set point
temperature of 6 hours and humidity of 17 hours. Loading 1 kg of roasted coffee takes time to reach a set
point of the temperature of 7 hours and humidity of 18 hours. Then for the burden of roasted coffee, 2 and 3
kg reach the set point at 8 hours and 10 hours, while for humidity, the same 18 hours. Adding a fan to the
system increases the time the storage system reaches the set temperature of 23 ?. |
