Why Should Coffee be Dried Before Processing
Coffee ranks as one of the most perishable crops. Coffee processing involves washing and pulping of the coffee berries before fermentation, and afterwards, coffee should be dried. Proper drying ensures that there is proper fermentation of the berries and also contributes to the flavour of the coffee. Additionally, coffee beans attract many insects and micro-organisms when left in a moist condition. These insects and micro-organisms introduce bacteria to the beans thus causing them to rot. Therefore, it is important that the farmer makes sure that coffee beans have been appropriately dried before storage using appropriate methods such as coffee solar dryers.
Traditional approaches to coffee drying
Traditionally, farmers would dry coffee berries on wooden raised table structures fitted with a wire mesh bed. The coffee cherries would be spread thinly and they are dried through direct solar radiation and wind movement. This process has several issues associated with it, such as:
- Firstly, the method is labour intensive since workers must turn the cherries over every 45 minutes to 1 hour to ensure even drying
- Additionally, farmers must cover the beds in the evening or on rainy days with a polythene cover to prevent moisture entry thus increasing the cost of coffee cherry drying.
- Quality degradation also occurs as a result of moisture entry, dirt, insect sand other contaminants.
- Furthermore, the method requires a lot of space because the beds cannot be arranged on top of each other
- Lastly, workers could fail to turn the beans over properly which would result in uneven drying.
Because of these challenges, coffee solar dryers have become the preferred alternative to traditional solar dryers for most farmers in Kenya.
What are Coffee Solar Dryers?
A solar dryer is a structure that is used to dry crop harvests such as coffee, vegetables, cereals and fruits. In most cases, the manufacturer equips coffee solar dryers with drying chambers, in addition to ventilation and insulation materials.
Aqua Hub Kenya’s coffee solar dryers are designed using various materials depending on the type of dryer a farmer needs. The dryers can consist of wooden or metallic structures covered with a polythene cover. This allows coffee solar dryers to withstand harsh weather conditions.
How a Solar Dehydrator Works
Solar radiation heats the air in the dryer that then comes into contact with the coffee. This causes the moisture in the coffee beans to rise. The ventillation system then expels this moisture. This process reduces accumulation of high moisture content in the structure. Consequently, the high temperature paired with adequate air circulation ensures the coffee beans dry evenly and at a much faster and convenient rate.

Coffee Solar Dryers Sizes and Prices
The cost of coffee solar dryers can range between KES 150,000 – KES 1,000,000 based on the size of the structure. The size of the dryer depends on the quantity of coffee a farmer intends to dry along with the location where it will be constructed. A small dryer of 3 meters by 3 meters by 2 meters can dry approximately 50 to 90 kilograms which a larger 8 meters by 30 meters dryer can handle over 700 kgs of coffee depending on the number of tiers in it.
The table below details the sizes and costs available at Aqua Hub Kenya
| Size of the dryer (Meters) | Cost (KES) |
| 3 x 3 x 2 | 150,000 – 175,000 |
| 5 x 8 x 2 | 280,000 – 320,000 |
| 6 x 6 x 2 | 280,000 – 330,000 |

Benefits of Coffee Solar Dehydrators
Coffee solar dryers have a number of benefits for Kenyan farmers e.g
- First off, workers do not need to turn over the coffee beans manually to ensure even drying thus cutting down on labor costs
- Moreover, there is balanced drying of the coffee beans as the hot air can dry each bean uniformly
- Additionally, no external moisture enters the coffee solar dryers which reduces the occurence of mould or mildew
- Coffee also dries within half the time or less than what it would take under direct sun drying which makes the drying process more efficient.
- There are no external contaminants such as dirt that can come into contact with the coffee since the cover effectively blocks them.
- Furthermore, the polythene cover is usually UV treated which preserves the quality of the cofee beans by blocking out UV radiation.
- The cover also has anti-drip attributes so dew does not form on it and drip onto the coffee
- Finally, coffee solar dehydrators use the space available efficiently as the drying racks can be stacked on top of each other.
How to Install Coffee Solar Dryers
There are several steps involved in the installation of coffee solar dryers. These are:
- First, we create raised tables from timber or galvanised steel less than 1 meter in width and the length can be extended as much as the site allows. These tables can be stacked up to 3 levels with vertical gaps of 0.75 meters to 1 meter between the levels
- Next, a food grade wire mesh is laid over the tables to hold the coffee. We can also use shade nets or insect nets for this. This is because the perforated membrane allows free movement of the drying air below the beans
- Afterwards, we construct the galvanised steel framework over the tables to a maximum height of 5 meters and lay
- lay the polythene paper over the frame.
- Finally, we can place an insect net at the air entry and exit points to prevent insects from entering the solar dryer.

Coffee Solar Dehydrators Maintenance
Maintenance of coffee solar dryers involves regular cleaning and inspection of the drying chamber to prevent contamination. Farmers should clean and remove dust on the polythene cover regularly, since accumulated dust can block sunlight from entering the structure. Regular inspection of moving parts such as fans, solar panels, the polythene cover and battery cells should also be done. Because solar dehydrators get made to last for a long time, they reduce ongoing costs for the farmers.
