The lifespan of a fruit drying machine can vary depending on several factors such as the quality of the machine, the frequency of use, and the maintenance and care given to the machine. Generally speaking, a well-maintained fruit drying machine can last anywhere from several years to a decade or more. However, if the machine is not properly maintained or used frequently, its lifespan may be shorter. It's important to follow the manufacturer's recommended maintenance procedures and ensure the machine is cleaned and inspected regularly to ensure it operates at its best and to prolong its lifespan.
