Solar energy is a kind of renewable clean energy, which has the advantages of easy development and use, no pollution, and a huge total amount. Nowadays, most of the heat sources of dryers use electricity, gas, coal, etc. These methods are mostly adopted by some large factories and businesses. Although these heat sources can generate a large heat value, they are not suitable for some places that lack power resources and whose output is not large. In some areas with sufficient sunshine and lack of electricity, using solar energy to dry can not only greatly reduce the drying cost of users, but also more convenient and practical.
Economic benefit comparison
Last year, our solar dryers were exported to Fiji. Fiji is an island country located in the Pacific Ocean. The island has sufficient sun conditions and abundant fishery resources. Our customer, MR. Alan, after a full conversation with our technicians, bought an SL-A model solar drying oven. This model of solar energy dryer adds an electric heating device, which can dry continuously all day long.
After a period of use, the customer gave us a very high evaluation. This dryer can not only solve his daily food drying needs, but also can sell the dried food to the local market to obtain income.
After talking with customers, we made a cost statistics table for drying 200kg dried fish with electricity and solar energy respectively (the electricity fee used in this case has been reduced and exempted by the customer for the second purchase ), let’s see how much economic benefit solar energy can bring to customers.
| Comparison of economic benefits between solar drying and electric drying | ||
|---|---|---|
| Drying method | Solar drying | 電氣乾燥 |
| Material drying capacity | 300kg | 300kg |
| 乾燥時間 | 8h | 8h |
| Electricity consumption | 4.44kW·h | 184kW·h |
| Energy prices (vary according to different regions) | 2.2F$ | 2.2F$ |
| Operating cost | 9.768F$ | 404.8F$ |
It can be seen that in the case of drying the same amount of materials, the operating cost of the solar air collector is very low. It only consumes the cost of the circulating fan and the dehumidifying fan during the operation of the system, and no harmful substances will be produced during the operation. Under the sun, everything is a place to dry up.
Introduction of our solar energy dryer
Our small mobile solar dryer is a new product suitable for families, individuals, and small producers. Its temperature can be automatically controlled and adjusted by an intelligent temperature controller. The working temperature range is adjustable between 30-90 degrees. It can be used to dry vegetables, fruits, grains, meat, fruits, etc.
This product is small and flexible, avoids the influence of dust, rain, and other factors that are inevitable in traditional open-air drying, improves the drying speed, and the quality and color of the dried product are also better. Moreover, heat energy is generated by collecting sunlight, which saves a lot of dry electric energy. It is suitable for power-deficient areas and is an economical, green and energy-saving product.
