In the daily use of coffee machines, internal parts face the dual challenges of long-term high temperature and coffee acid and alkali corrosion. However, through clever design and high-quality material selection, these parts can maintain stable performance in harsh environments and continue to provide users with high-quality coffee.As one of the core components, the boiler of the coffee machine undertakes the key task of heating and storing water. In a long-term high temperature environment, the choice of boiler material is crucial. Stainless steel is an ideal choice for boilers due to its excellent high temperature resistance and corrosion resistance. It can not only effectively resist the thermal stress caused by high temperature, but also prevent the acidic substances in coffee from corroding the inner wall of the boiler. At the same time, the interior of the boiler is treated with a special coating to further enhance its corrosion resistance and extend its service life.The piping system of the coffee machine is also faced with the test of high temperature and acid and alkali corrosion. In order to ensure smooth water flow and no pollution, the pipes are usually made of high temperature and corrosion-resistant copper or stainless steel. Copper pipes have good thermal conductivity, which helps to improve heat exchange efficiency, but it should be noted that they are easy to react with acidic substances in coffee. Therefore, some coffee machines have been specially treated on the surface of copper pipes to form a protective film, which effectively isolates the direct contact between coffee and pipes. Stainless steel pipes, with their excellent corrosion resistance, have become a more stable choice, and can keep the inner wall of the pipe smooth and clean during long-term use.The seals of coffee machines play an important role in preventing coffee leakage and external contaminants from entering. Under high temperature and acid-base environment, seals are prone to aging, deformation and other problems, resulting in reduced sealing performance. To solve this problem, coffee machine manufacturers use high-quality rubber or silicone materials to make seals. These materials have good high temperature resistance and corrosion resistance, and can maintain stable elasticity and sealing in harsh environments. At the same time, the design of the seals has also been carefully optimized to ensure that they are closely matched with the coffee machine interior parts, effectively preventing coffee leakage and the intrusion of external contaminants.As key components for filtering coffee grounds and impurities, the filter and filter element of the coffee machine also need to cope with the challenges of high temperature and acid-base corrosion. The filter is usually made of stainless steel, and its fine mesh can effectively intercept coffee grounds and has good corrosion resistance. The filter element uses special filter materials, such as activated carbon, ceramics, etc. These materials can not only effectively remove impurities and odors in coffee, but also resist the erosion of coffee acid and alkali substances. Regular replacement of the filter and filter element can ensure that the filtering effect of the coffee machine is always kept in the best condition.Through reasonable material selection, special design and regular maintenance, the coffee machine interior parts can maintain stable performance under long-term high temperature and coffee acid and alkali corrosion. This not only provides users with a high-quality coffee experience, but also extends the service life of the coffee machine and reduces the cost of use.
