The heat pump dehydrator combines the best features of both conventional and energy efficient drying systems in one device. It offers excellent humidity control in the dryer chamber. The unit uses a dual and reversible airflow design to ensure strong, even heat distribution throughout the entire drying chamber. The system can also be controlled remotely. Nyle Systems FD series has an intuitive touch screen controller programmed with flexible drying scheduling software. Drying schedules can be saved, modified and easily retrieved for future use.
Atmospheric freeze-drying (AFD) combined with a properly designed heat pump is an energy-efficient drying method that can compete with traditional vacuum freeze-drying. It is suitable for high-throughput drying of food products. It has a lower production cost and produces a porous product similar to that produced by vacuum freeze-drying.
Various studies have been conducted to evaluate the performance of heat pump drying. Its effectiveness was compared with other drying methods including vacuum drying, convection drying, and radiation drying. The results showed that the quality of the dried product was comparable to those of vacuum freeze-drying. A heat pump drying system can be used for the dehydration of many different types of foods and crops.
Traditionally, most fruits and vegetables are dried outdoors or in commercial drying machines using gas or electricity as heating sources. However, successful outdoor drying requires good weather conditions. Furthermore, excessive temperatures can damage the nutrient content of the product. Consequently, it is crucial to explore alternative heat sources. heat pump dehydrator
