We Craft Elegent Solutions with Powerful TechnologySolar Dryer Parabola Dome is the result of 30 years of research by Dr. Serm Janjai of Silpakorn University. The dryer works with the principles of greenhouse drying for agricultural products such as bananas, tomatoes, chili, coffee, cocoa, spices and herbs, etc.
Their parabolic shape allows the best use of solar radiation, and rain water runs off easily. The polycarbonate sheets used to cover the dome creating the greenhouse effects are made of high-value, high-quality Covestro polycarbonate, and are coated with a UV protection layer. Being shielded from UV, agricultural produce keeps its vibrant colors and valuable nutrient values. This results in higher valued final products. The dryer is easy to transport, and is installed locally. It reduces significantly the risk of spoilage and hygiene concerns caused by dust, water contamination, and livestock animals. |

We Promise You the Best Solution in DryingDRYERS TYPE:
Conventional/Traditional Drying (Open Sun Drying) Electrical/Mechanical Dryer Solar Dryer (PE: Polyethylene) Solar Dryer (PC: Polycarbonate) Conventional Drying/Traditional Drying (Open Sun Drying) Advantages Low cost, widely practiced and could dry higher capacity. Disadvantages Unhygienic (food contamination), labour intensive, poor food quality and flavour Atmospheric Moisture Uncontrolled Warranty None Electrical/Mechanical Dryer Advantages Faster drying time, more hygienic and an option to conventional drying. Disadvantages High operating cost, high electricity cost makes products economically unfeasible. Atmospheric Moisture Controlled Warranty on Machine Mostly one to two years on mechanical parts and costly to change Solar Dryer (PE: Polyethylene) Advantages No electricity required, hygienic Disadvantages Requires space, low durability (PE has to be changed every 3 yrs) high investment cost for individual farmers and requires LPG if high altitude No electricity required or low maintenance cost, hygienic and UV protection for better food colour and quality. Atmospheric Moisture Moderately Controlled Warranty on PE Covering - 3 years (Need to be changed after 3 years) Solar Dryer (PC: Polycarbonate) Advantages No electricity required or low maintenance cost, very hygienic Disadvantages Requires space, high investment cost for individual farmers and requires LPG if high altitude Atmospheric Moisture Highly Controlled Warranty on Polycarbonate Covering PC sheet has 10 yr warranty SOLUTION - SOLAR DRYER DOME USING COVESTRO POLYCARBONATE COVERING |
