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. Technical data: Roaster capacity: 15 Kg. | Max. 19 Kg./ Cycle Roasting cycle: 9 Minutes 20 Raw coffee processing per hour: 60 Kg. 90 Installed electric power: 1,8 Kw | 380 Volt Threephase + Neutral 50 Hz Thermal power: 24,000 Kcal/h/ 29 Kw. (Natural gas or LPG) Main components: Hopper of charge in stainless steel Roasting drum Heating generator of new generation patented and complete of burner Ramp valves for gas safety and electric device to check flames ratified and complete of alarm signal. Cooling tank in stainless steel with door for cleaning operations Safety prevention system on the cooling tank Supporting frame for the over indicated components Electric control board to check and control the machine according CE rules, complete of PLC + Touch Screen for machine management and temperatures sight. Independent fans for the roasting drum and the cooling tank Independent motors for the roasting drum and the cooling tank Cyclone for chaffs collecting Details of components: Hopper of charge in stainless steel with manual in-let of coffee and door unloading system Roasting drum: made by a fixed element with double walls insulated for thermal protection and support of the rotating cylinder moving the product. Such cylinder, completely made in compound steel to overcome the thermal changes, is developed with a perforated plate for the containment and special blenders on the right and left side placed on different levels to get a perfect blending of coffee. At the end of the roasting cycle, a wide door with manual opening/closing system allows the product unloading. Heating gas generator of new concept, patented, complete of burner, ramp valves for gas safety and electronic equipments for flame control ratified and complete of signalling alarm (n2 flame levels) Cooling tank in stainless steel: wide surface perforated with 3 arms and crossed flows. Unloading mouth with hand drive. Supporting frame: mono-block, plate press-bended, steel made, supporting the elements previously described.
