The milk burning happens with different criteria under different circumstances. Various factors are causing this. There are two common types of milk burnt.

One is the sticking of milk content on the internal surface of the pan. 

It is a process of scalding in which the milk will get separated into water & protein content internally where the temperature is 181 F. 

If the temperature rises more than that, the water settles down, and milk foam spills out and burnt on the surface of the milk pan. Then milk will burn easily.

Next is, Sticking of milk content on the bottom of the pan or milk frother

This is the scenario that happens at the milk frothers. Here, when there is an uneven distribution of heating will cause the milk to stick at the bottom of the pan by concentrating locally. This causes the milk to burn easily rather than the former one.

When seeing the nature of material science, there are various types of steel material with various capacities of the rate of heat transfer. Also, the rate of heat transfer depends upon the thickness of the steel material.

The Nespresso milk frother is made up of stainless steel. Stainless steel has its capacity for heat transfer. When the milk frother is turned on, started to froth along with the heating.

The heating coil beneath the bottom plate of the frother generates heat. The same heat is transferred to the bottom plate of the frother. 

The burning of milk or any liquid will not happen when the intensity of heat flame produced in the coil transfers to the bottom plate through the same intensity.

But sometimes, unfortunately, due to the relation between the heat-conducting capacity of the heating coil in milk frother& the heat-conducting capacity of the stainless steel material, the intensity of heat flame producing at the coil is more than that transmitted through the bottom plate.

So higher the heat flame outside, the lower the heat which going inside the frother, the balance unabsorbed heat is instantly transmitted to the bottom plate of the frother by concentrating locally where it is feasible.

This causes the proteins and lactose in the milk to get burnt & coagulate each other and stick to the bottom plate of the frother.

Higher the thickness of the plate, the distribution of the heat at the bottom of the frother is uniform. Even though the intensity of the heating coil matters.

Before starting the frother on, we need to make the inside of the frother wet as much as possible. For that, we need to pour some cold water(or running water) into it and rinse it for few seconds. 

Also, let the cold water inside the jug for few minutes until it is cool inside to touch. Then drain the water & pour milk to begin frothing. This will prevent the instant heating of milk. 

The wet layer between the bottom plate and the milk forms the layer for distributing the heat uniformly over the bottom surface and acts as an anti-burning layer.

Tip 4:(Do not overdo or repeated froth cycles)

Although the Nespresso milk frother is water-resistant. Do not submerge the frother inside the water. 

Do not keep in contact with the frother’s heating coil(outside surface) with the dishwasher liquids. The heating coils beneath the bottom plate are not designed for dishwasher chemicals.
