As the weather gets hotter, many people are considering buying ice cream machines, but so many manufacturers, how to choose ice cream machine has become the most headache for most people. I have been operating the refrigeration industry for many years and put forward the following suggestions: The most important components of an ice cream machine are the motor and the compressor. The motor is the heart of the ice cream machine. The compressor is the brain of the ice cream machine. These two sets of accessories are essential! Most of the ice cream machines on the market use domestically produced engines. The compressor market is also made in China. However, because of the limited level of technology in China, the life of the compressors produced is only 3 to 5 years. Of course, domestically produced. The compressors are also good, such as Dongbei, Qianjiang, and the other two brands are not so good. With the improvement of people's living standards, some powerful manufacturers have begun to prefer to import compressors from abroad, such as the Italian imported compressors of Ruiqi ice cream machines. This compressor is a fully enclosed compressor, which has better cooling effect and more energy saving. And the use of longer, the average life of Italian compressors is more than 15 years.
