Business Coffee Machine
The ideal temperature for coffee is 185 degrees. Anything that is hot, over 100+ degrees is very hot and should be handled with caution. Restaurants are or should be around the same temperature. There are some places I've gotten coffee where it's probably been around 160 degrees. So, temperature sensor is the key point for coffee machine.

The Working Principle of Business Coffee Machine
The current coffee machine often stores heat in advance by increasing the thickness of the electric heating plate, and uses a thermostat or a relay to control the heating, and the heating overshoot is large, so it is necessary to install an NTC temperature sensor to strictly control the temperature accuracy.
When the NTC temperature sensor judges that the temperature is lower than 65°C, the heating device will heat at full power; Switch back to 20% until it is heated to the heat preservation state; this preheating process makes the temperature of the electric heating plate rise rapidly in the early stage, and slowly heats up in the later stage, so that the temperature can be raised quickly, and the temperature accuracy can be well controlled to ensure that the electric heating plate will not be caused by The temperature hysteresis of the temperature sensor leads to the overheating of the electric heating plate, which can ensure the temperature accuracy at the moment before the coffee is dispensed, and reduce the variable factors in the coffee dispense process.
