Gas Pressure Control：
Gas pressure controls the fire flame strong or weak, we use the high quality gas meter and knob switch for controlling the gas volume to roaster.
Press “Heating” button, the solenoid valve opened to connect gas, if burner produces fire flame, then LED button light up; if the burner doesn’t produce fire flame in 10 seconds, the solenoid valve will automatically close the gas, the buzzer gives an alarm.
Constant-Temperature Control ：
Temperature value can be preset, when the actual temperature is up to it ,machine automatically cut off gas and stop heating up; when temperature drops below the preset value, it ignites the fire to heat up automatically, the temperature keeps in same preset value all the time.
Roaster Drum: It is made of 304 food level stainless steel and mixing blades attaches inside the drum by TIG welding, clean and low noise.
Gas Burner： High performance burner produces strong fire flame to help you easy control your roast, fuel saving. Temperature rise can be reached 20C/minute to fit your ever-changing roasting requirements.
Insulation Layer: Even for our smallest coffee roaster, we still use the very thick insulation layer, maximum reduce the heat loss.
Omron Temperature Controller
“SV” (The green color digital number) is the preset temperature.
“PV” (The white color digital number) is the actual temperature .
“°C ” is for degrees Celsius, it can convert to “°F” Fahrenheit degree.
Example : Preset temperature is 230 Celsius degree, when real-time temperature is up to 230°C, the machine automatically shuts off the gas to burner; and switches on the gas and ignites the fire on burner when temperature drops below 230°C .
Machine equipped with an automatic gas detection system for flame off. If the flame is off in unexpected condition, the machine will automatically cut off the gas, the buzzer gives alarm.
