The performance of solar tunnel dryer was tested at no load and with load condition. Maximum average temperature was observed during no load test in solar tunnel dryer was 45.6 °C and solar
Solar Tunnel Dryer 5 Speed of drying by open air-drying and Solar Tunnel Dryer 6 Benefits of solar drying . Can open new markets and income and is a good start-up technology. It improves the bargaining position of farmers. Sometimes farmers sell at very low prices during the harvest season ; You can have up to 50 more productivity in agriculture
Lutz et al. [27] developed a multipurpose solar crop dryer comprised of a solar air heater and a tunnel dryer for drying various agricultural products (Fig. 3).As compared to the traditional sun drying methods, the drying time and mass losses were reduced significantly with the payback period of 1–3 years.
SUNLIT Solar tunnel Drier is an enclosed chamber which is used for drying of various crops using Green House effect. It helps to preserve the food and also increase the shelf life of the product. It is covered with multi wall Polycarbonate sheet which traps solar energy and has an insulation effect, thereby maintaining high temperature for a
The solar tunnel dryer performance is evaluated by using single, double and three layers of mint, and compared with open sun drying. Predicted and experimental moisture ratio of mint leaves using developed solar tunnel dryer were compared through several models of thin-layer drying. The effect of embodied energy of the developed hybrid solarA multi-purpose solar tunnel dryer, orginally developed for the use in arid zones, was modified to enable operation under tropical weather conditions. This type of dryer consists of a small centrifugal blower, a collector and a tunnel drying chamber. To prevent penetration of water into the construction and subsequent flooding, the solar dryer HDj21YF.
