Solar Collector Dryers to Increase Economic Value in the Community
Keywords:
Drying, Solar Collector, Solar energy, Solar Drying CabinetAbstract
The objective of this research is to develop, build and determine the efficiency of the Solar Collector dryer by comparing the percentage of moisture and weight of the products obtained from the Solar Collector dryer with the solar drying cabinet and drying by natural method The product used in the experiment was Nam-wa banana.
From the experimental results It can be concluded that the Solar Collector's solar dryer has an average hourly radiation that hits perpendicularly on an inclined plane at 633.06 W/m2. The efficiency of the solar collector panel at any time is between 18.18 - 47.75 %. The solar collector has transmits high solar radiation absorption values and prevents heat loss well.The efficiency of the solar collector panels that were created was 99%. The results of comparing the moisture percentage of the products from drying Nam- wa bananas, tested for 1 day and 5 days, calculated according to wet food standards, found that the average moisture percentage of Nam- wa bananas from The Solar Collector solar dryer can reduce humidity better than Nam-wa bananas from solar drying cabinets and from natural drying methods. Represented as 58.22, 56.02, 55.64 and 74.29, 72.99, 71.94 percent, respectively. The weight of Nam-wa bananas from drying 5 times, 5 days each time. The Solar Collector dryer was able to reduce the weight of Nam-wa bananas the most. From solar drying cabinets and from natural drying methods. The weight of Nam- wa bananas decreased on average to 0. 35 kg, 0. 37 kg and 0. 39 kg, respectively and when there is a production capacity of 20 kg/ time Will be able to payback the investment with in approximately 9 days, with a net income of 52,459. 68 per year.
