COST EFFECTIVE FOOD PRESERVATION
Grekkon offers solar dryers in Kenya for agriculture to meet food drying needs by growers, processors, and consumers. Our solar dryers are available in the eat African region to commercial farmers who sell dried foods to international markets and local retail outlets. These low cost solar dryers are constructed from food grade material- from the structural system to the cover. They are environmental friendly, enhance energy conservation and dry four to five times faster than open air draining. Our solar dryers for agricultural products are an effective means of food preservation, and add value to highly perishable foods.
Natural solar dryers in Kenya for agriculture utilize sunshine to heat up air that dries the food product in it. It is an easy way to add value to food crops and meat which is beneficial in reducing wastage of excess agriculture production. Open air drying faces many challenges such as;
- degradation of food value by ultra violet rays (UV)
- susceptibility to insect pests and rodents
- dirt contamination
Grekkon Limited’s solar dryers are constructed on location for large fixed and portable sizes, or inpur store and later transported to site for small portable units
There are no standard sizes because each dryer is constructed on site according to the food material and volume to be dried per drying session. However, we do have common sizes by growers as per the tabulation below

How A Solar Dryer Works
Heat diffuses into the dryer from all sides heating up the air within. This air is allowed in through an inlet vent and once heated, it escapes with the collected moisture from an outlet vent and the cycle continues till all moisture is dried off from the food. Grekkon dryers are designed to preserve the original food color, taste, scent and full nutritional value. This is achieved by use of UV treated cover and floor material, and food grade zinc or aluminum galvanized structure
How To Use Solar Dryers For Fruits And Vegetables
i. Chop or slice the produce into smaller pieces. This increases the surface area for drying
ii. Place these pieces on the drying trays
iii. Keep the door closed always to avoid food contamination
iv. Every drying 3 hours, monitor the moisture content using a moisture meter
Solar Dryers in Kenya For Agriculture
1. What are the 2 types of solar dryers?
1.1. Passive solar dryers. They only utilise the sun’s warmth
1.2. Active solar dryers. These ar hybrid solar dryers that utilise both passive drying and biomass generated heat
2. How do you make a solar dryer?
Grekkon limited’s low cost solar dryers in Kenya are made from the following materials
2.1. A zinc or aluminum galvanised steel structure. It is rust free and easy to clean with plain water
2.2. UV treated greenhouse polythene with anti-drip properties. The UV treatment prevents food degradation by the sun’s UV rays. It ensures that the color, taste, scent, and nutritional value remains after the moisture is removed. The anti-drip treatment prevents moisture droplets from condensing on the paper and forming drop that will fall on the food. Such drops cause moulding
2.3. A heat absorbent floor. his one absorbs heat during the day, and releases it at night reducing tea variance between day and night temperatures. Dew formation and mould development is aggravated by a huge difference between day and night temperatures
2.4. A UV treated heavy gauge insect net to protect the produce from insect pests. This insect net covers the air vents
