ABSTRACT:
A large scale, industrial system and method for dehydrating fruits, nuts or other produce. The system includes two long air tunnels which are placed end-to-end. Each air tunnel has a conveyor which is used to transport the produce through the air tunnel. As the produce exits one air tunnel, it is dropped from one conveyor onto the other, thus permitting the produce to be turned over before it enters the second air tunnel. Each air tunnel is divided into a number of separate air chambers in which the heated, circulating air is confined so as to reduce heat loss, thus increasing the energy efficiency of the system, and also providing for separate control of the air temperature and humidity levels in each air chamber. Countercirculation of air between adjacent air chambers aids in confining the air through the separate air chambers, as well as the use of resilient flaps which are used to enclose the ends of each air chamber through which the conveyor enters and exits. A high volume rate of air flow is directed generally parallel to the direction in which the produce is transported through the air chamber, thereby enhancing the dehydration process.
