Description

With the brand new Solar Coffee Roaster you can discover for yourself the advantages of roasting coffee with the sun’s rays. Because this coffee roasting machine uses the sun’s energy instead of gas to heat the coffee bean drum. 100% renewable and ecological energy. Coffee roasters around the world have long been looking for ways to minimize energy consumption and their ecological impact. For a few years now, some companies have decided to power their roasters with renewable energy. Thus, to heat the roasting ovens, the electricity produced by the solar panels housed on the roof is used.

But from today we can roast coffee directly from the sun’s rays instead of transforming solar energy into electricity. To roast coffee we use motorized mirrors that automatically change the inclination based on the change in the position of the sun. With this system we manage to keep the sun’s rays focused on the roasting drum for the entire day. Of course, the energy needed to move the mirrors is self-created using solar energy.

How the Solar Coffee Roaster Works

We created an eco-friendly coffee roasting system that uses mirrors to concentrate heat from the sun on a rotating coffee drum. The roaster is 100% self-sufficient and requires no external power to operate. Of course, there are small disadvantages to using a solar roaster for large businesses. First of all, you have to rely on the sun and it is not possible to plan a long-term roasting program. Because you can’t rely on the solar roaster if it’s cloudy and raining. The second point against is a question of space. You must have a plot of land exposed to the sun capable of hosting 30 mirrors with a diameter of 400mm each. While the mirrors must necessarily be placed outdoors, the drum can be mounted inside a shed. All you need is a glass opening in the building that allows sunlight reflected by the mirrors to pass through.

Roasting Coffee with the Sun’s Rays is Healthy and Sustainable

Roasting coffee by irradiation with sunlight offers numerous advantages compared to roasting in an electric or gas oven. First of all, it is able to produce greater roasting uniformity. This is because this method uses the electromagnetic energy of light emanating from the sun and roasts the entire bean evenly. While traditional roasters work by heating the rotating drum which in turn heats the air inside it. So the hot air heats the coffee beans, but only on the surface. This often results in beans with the center still raw while the surface is always a little burnt.

Second, using sunlight instead of gas or electricity has a significant environmental impact. Suffice it to say that to roast 1000 Kg of coffee you need 200 cubic meters of methane with a classic roasting system. That is, with solar torrefaction you avoid producing and releasing 400 Kg of CO2 into the atmosphere. As you can see, you also have great savings on your energy bill. We are aware that roasting coffee with the sun’s rays is not for everyone. But it can be interesting for a roastery with moderate production, especially if located in sunny areas. It’s an interesting idea and definitely worth pursuing to reduce the environmental impact of coffee.

Why Roast Coffee Using the Sun

Compared to classic coffee roasting technology, roasting with the sun is extremely advantageous. First of all, solar coffee roasting is 100% ecological because it uses the sun to reach the roasting temperature. Secondly you save a lot of money on gas bills, because the gas oven is a thing of the past. Third, our solar coffee roaster is 100% independent. You can also install it in areas without an electricity or gas network. Because the only energy it uses is that of the sun.

Fourth, thanks to heat transfer technology, the coffee receives the energy to roast more efficiently. In fact, the method of roasting coffee with the sun’s rays allows you to achieve 100% uniformity and avoid damage or burning of the beans. The coffee beans are roasted by the sun’s electromagnetic rays and not by metallic contact with the drum. In fact, in conventional roasters it is the drum that is heated with gas and which transmits the heat to the coffee beans. Fifth, since there are no combustion fumes, you will get a clean, bright coffee flavor. This is why solar roasting technology is ideal for roasting full-bodied espresso coffees. And last but not least, our solar coffee roaster requires no maintenance as there are no moving parts except the rotating drum.

Solar Roasting Can Increase the Earnings of Coffee Farmers in Remote Areas

Most coffee farmers are located in remote, non-industrialized areas of South America, Africa and Asia. And they sell their coffee beans as harvested and only a little dried. This is why their selling price is very low compared to the final price that consumers pay for the coffee.

Roasting, in fact, is the activity that gives the true value to coffee. But these farmers are not able to install a classic roasting system and make more profit from the sale of roasted coffee. This is because standard roasters rely on electricity or gas, all energy sources that are not available in rural areas. But from today even farmers in the most remote locations have the opportunity to increase the value of their coffee. And consequently increase your income. They can install this economical roaster that runs completely on solar energy. In fact, in this coffee roaster the sun’s rays heat the drum to a temperature of 250ºC. The standard temperature that is reached in gas roasters.
