Solar drying in Cambodia.
Solar drying of agricultural food products is one of the most attractive and cost-effective applications of solar energy.
As one kind of inexhaustible, safe, energy saving, environmental protective new energy, solar energy is getting more and more attention in this world.
Advance: time saving, weather resistance (wind and rain are not anymore an obstacle), higher hygienic standards is higher product quality and color & taste, less pollution, no fungus, no animal, higher nutrients value, inside temperature control & increase income.
In view of the high demand of energy resources and nonsustainability of conventional energy sources, such as fossil fuels, it is imperative to continue to explore alternative methods of drying in a sustainable and more effective and efficient way, making use of renewable energy sources.
Drying is simply a process in which agricultural products can be preserved for future use by removing enough moisture from the crops in order to avoid decomposition, since moisture in many categories of agricultural produce makes them prone to perish more easily, especially in tropical climatic conditions.
Solar energy remains a viable and economical means of preservation of agricultural products, since the heat from solar energy can be applied in either traditional open air drying or with specially designed solar thermal dryers to prevent post-harvest losses which are a common phenomenon in many developing countries.
What can you use Solar for?
For all vegetables that can be dried, herbs, seeds, carrots, spices and for all fruits. Anything that can be dried can be used for this.
The solar dryer decreased the mass of cassava from 30.8 kg to 17.4 kg within 13 and 9 h at average temperatures of 40 °C and 45 °C, respectively. The moisture content of cassava decreased from 61% (wet basis) to 10.5%, see the pictures of drying mango and jack fruit. Other products as chili, fermented cocoa beans, coffee berries, banana, papaya, sliced meat, seaweed, fish and it has great potential for application in the rural areas.
Our Solar dryers are covered with polycarbonate sheets at a parabolic-shape. The parabolic cross- sectional shape helps to reduce the wind load in case of tropical rain storms.
Polycarbonate has 100 percent protection from the sun’s harmful UV light.
- Economy; It is up to 4 times cheaper
- Resistance: It is virtually unbreakable; endures all hail; 200 times more resistant than
- Lightweight: Weighs 3 times less than the glass.
- Security: A traditional glass module released by wind or poor subject represents a great danger to people and materials by weight and
- Utility: flexible, easy to work, can be drilled and cut ea
Tray layers are made from HDPE nets (Products made from Type 2 HDPE recycled plastic are considered Eco–friendly because they are made mainly from post-consumer products and are recyclable at the end of their useful life. … HDPE plastic is the most environmentally stable of all plastics – giving off no harmful fumes into the environment.)
We are proud to present the Bangkok University developed solar dryers of Covestro where Baca-Villa is the exclusive distributor in Cambodia.
