As the core component of the milk warmer, the heating plate of the milk warmer is usually made of highly efficient heat-conducting materials, such as stainless steel or aluminum alloy. It has the characteristic of rapid heating. After being powered on, it can heat up in a short time and accurately maintain the appropriate heating temperature of the milk, generally with very little fluctuation between 37℃ - 45℃, effectively avoiding overheating of the milk and destroying the nutrients, and providing the baby with warm and appropriate food at any time. Its surface is often specially treated, smooth, easy to clean, and corrosion-resistant, ensuring stability and safety for long-term use.
