15 kilo: STA Impianti Roaster

STA IMPIANTI 15K ROASTERSTA is a manufacturing group in Italy - that is made up of seasoned engineers from most of the big old Italian roasting machine makers - so their scope of knowledge and history is fantastic. Basically - their claim to fame is hot air introduced into the top of the roasting chamber . . . being pulled through the turbulating coffee and exiting through drum perforations into the bottom.

First, that makes it really friendly to blending formulas and second it makes for smaller chaff - as the turning coffee beats it up a little and thus the roast comes out more clean than the old days of some solid drums . . . so it is different - which does not make it better - but if you have a background on Jabez Burns . . then you will really love this production. Big naturally developed beans - very even roast.

Following is the manufacturers specs and we will be glad to discuss more in-depth as you have questions.

Roasting machines line particularly suitable for artisanal specialized activities in medium batches of high-quality roasted coffee, such as artisan market or coffee shops. Technologically advanced, confirms themelves as ideal tool for roasting companies specialized in selected coffees of higher quality.

Made with the same requirements for reliability and security features of the bigger and more sophisticated industrial roasting machines, are available with heating generator type gas or diesel-fuel burner at multiple levels of flame and manual or automatic control system.
