Automatic Coffee Roaster: Solar 2 Kg

 

 

 

Solar coffee roaster was launched in 2006 as the third generation of our innovative Shop Roasters project. 

The cutting-edge machine showed early promise and became since the most common piece on our manufacturing tables. Hundreds of Solar coffee roasters were sold worldwide to very happy customers. These years of experience helped us to reach perfection. We now can confidently claim that the Solar falls no short of being the best roaster in every way.
The Solar excels in its superb roasting quality, plug-and-play operation, compact design and exceptional reliability with no maintenance needed. Thanks to these features, it’s no wonder it was adopted by many micro roasting startups, specialty shops and coffee bars. Until now, no other shop roaster was able to challenge the Solar – the most advanced shop roasting machine in the world.

The Solar Unique Technology – Planner’s Perspective

Solar was designed according to a long list of requirements and constrains derived from our extensive study and experience. The roaster had to be capable of roasting a pre-blended coffee at the highest level. Another precondition was to make it 100% electrical using low consumption 230V, single phase. This in order to save the user of the “pleasure” in dealing with gas (we know, some people believe they need to have gas even for their shop roaster… we can talk about that later). Having said we specified this particular roaster to work in shops, we wanted it to be safe, quiet, clean, easy to maintain, automatic and produce the lowest possible amount of pollution. We also wanted to eliminate the risk involved with having an outer cooling unit with accessible agitation blades. It had to be compact with the option for countertop placement and above all – maintenance free! That is why the chaff blower needs no cleaning as opposed to any other shop roaster where cleaning is needed weekly or monthly. Solar needs no greasing or any other special maintenance other than emptying the chaff bucket and cleaning the duct.

 

The Secrets of Solar Roasting Quality

The only traditional thing about the Solar is the outer shape, all the rest is a well studied unique Coffee-Tech technology.
The solar is the only machine in the world that combines between "drum roasting method" to "fluid bed roasting method". Laboratory tests proved that inserting few seconds of fluid bed roasting every few minutes of drum roasting produces superb uniformity in the batch, thanks to the exact ratio between conductive heat to convection heat transformation. This with the Infra-Red radiation treating not only the beans that are with direct contact with the drum, but also the "flying" beans. 
This means that in the solar roasting process, we activate no less than four heating methods at once, being a great help for achieving uniformity, full aroma and flavor developing.
The "in drum cooling" is so powerful and effective even more than the outer cooling group, this ensure blocking the roasting cycle immediately, preserving the maximal amount of sugar, oil, aroma and flavor, the "in drum cooling" reduces the drum temperature to the correct point for inserting new batch.
The drum and the heaters have minimal thermal mass, so they loose the heat as soon as the cooling starts.
You can always decide to end the roast manually and use the outer cooling group in the Solar.

About the Automation

In fact, you may call it a manual machine, but with good repeatable memory for your most successful setting, isn't it something really nice to have?
The Solar is featured with very smart dual temperature controller, allowing you to set the temperature you desire to start the roast and the temperature you would like to end it, in between the Solar also featured with small computer loaded with our advanced "roasting management software", to take care of the rest, the options are almost endless.
Our Roasting management Software was developed in our laboratory, based on our years of experience in coffee processing machines design-coffee roasting-cupping-enthusiasm, baked by extensive laboratory tests of the results in the cup. 

Writing the automation software was a very easy job; because of the high technology of this machine, the Solar needs no manipulations to produce top quality batches time after time, as we explained earlier, the machine thermally treats every single coffee bean "personally" in a few methods, the machine is accurate, well calibrated in its nature, efficient and represent the next generation in the roasting world, most traditional gas roasters are "wild" in their nature and needs to be manipulate in order to achieve decent result while the Solar gets higher and further by pressing only one push button. 

As one of our customers reported soon after upgrading to Solar: " we were doing coffee by rotating barrel on flames, now we are Roasting!"
