The Solar Powered Air Dryer is new and innovative technology basing on blending Solar Thermal and Solar Photovoltaic Technologies.
Applications:
The Solar dryer can be used to dry a variety of agricultural products and food items such as:
- Fruits (Grapes, bananas etc.)
- Vegetables (Potatoes, Onions etc.)
- Grains (Paddy, Wheat, Maize etc.)
- Spices (Ginger, Garlic, Chills etc.)
- Cash crops (Coffee, Herbs, Flowers etc.)
- Fish and Meat
- Mushrooms
Advantages:
- Solar thermal power is trapped, resulting in a higher temperature around the food items. This decreases the drying time.
- Higher conservation of nutritional value.
- Animals and dust do not have access to the food items.
- In rainy periods, rain will not slow down the drying process.

Working principle:
The Solar radiation passes through the transparent glass window, located on the top of the cabinet, which is oriented to south with a tilt angel equal to the latitude to collect maximum radiation. The cabinet made of anti-corrosive material and of modular nature to meet the varying sizes and loading capacities of products, ranging from 8 to 50 kgs and above.
The ambient air enters from the bottom of the cabinet and gets heated up with Solar radiation incident from the top window. The heat energy is trapped in the cabinet and heats up the air. As a result the wavelength of Solar radiation shifts to infrared region, causing green house effect. The hot air passes through the trays, carries the moisture from the product to the space below the glass. Then, Solar Photovoltaic fans exhaust it. The forced air circulation of air in the cabinet is achieved through this Solar fan. The electrical heaters are provided as standby to meet any exigencies on non-sunny days.
The figure illustrates the SOLAR POWERED AIR DRYER. It has a capacity to evaporate 15 Kgs of water per day from the processing product and a maximum loading capacity of 50 Kgs of wet products.
We design commission and install the industrial Solar drying systems as per the customers' needs and requirements. System details can be sent to the Customer upon receipt of specific requirements from the customer.
