A food dryer dehydrator is a piece of equipment that takes moisture out of different foods like nuts, fruits, and vegetables. By eliminating moisture from food using different heat sources, such as convection or radiation, a food dehydrator helps to preserve the food products. Hotking Scientific Instruments, one of the top food dryer dehydrator manufacturers in India, combines its expertise, know-how, and experience in the production of food dryer equipment. One of India's top manufacturers of food dryers and dehydrators.

Different fruits and vegetables would remain available for a longer period of time if their shelf lives were extended. To help with this, there are numerous post-harvest processing techniques available. The'shelf-life' of many fruits and vegetables can be extended in a reasonably practical method by drying them. Dried food items can be enjoyed for several months after freshly harvested regional produce has vanished from the local markets with the right treatment and storage.

These days, food dehydrators use heated air flow to lower the water content of food items while using low-power convection.
