In stock. Delivery time 1 to 4 days.
The roaster must have a defined temperature (typically in the “traditional roasting process” 100°C to 260°C) or a set temperature curve (readable via USB port with Artesan software – included in delivery). The energy supply from the roaster to the beans occurs either by electric heating in Model 1 or by gas heating (propane gas) in Model 2 through contact and convection. During roasting, the coffee must be constantly circulated to ensure even heating of the roasted material and an even degree of roasting. The water originally contained in the green coffee beans (between around 12 and 18 percent of the bean weight) evaporates, which is referred to as branding. During roasting, checks of color and other sensory criteria are often carried out, manually using a sampler or visually using a sight glass in the roasting drum. When the roasting process is finished, the coffee must be cooled quickly so that the beans do not continue to roast or burn from the inside. This takes place in the airflow of a cooling sieve outside the roaster.
Both roaster models are equipped with two powerful blower systems. One is used to circulate air in the roasting room, the proportionality is adjusted by the clear, adjustable mixing valve between circulating air and exhaust air, the second is used to cool the beans after the roasting process. Both aluminum-coated exhaust hoses are included in the scope of delivery.
The roasters are manufactured in China by our technology partner according to our specifications and specifications. They are tested in our company for technical flawlessness and roasting results, and connections and guidelines are adapted to European standards. We have been selling this type with further developments based on experience for almost 5 years. Spare parts deliveries are guaranteed. During these years we have not received a single complaint, which makes our roasting department very proud.
This roaster size (1 -1.5 kg) has the optimal capacity for roasting small quantities of coffee for test roasts, roasting according to customers' specific requests or simply to be able to offer customers freshly roasted coffee at short intervals. With roasters of this size, green coffee potential and its properties can be determined, coffee qualities can be produced for tasting in small batches and blends can be tested. Sample roasters are also a great help in determining and creating roasting profiles (optimal temperature and roasting time) for larger systems and in ongoing quality control.
Undertables for our roasters are not included in the scope of delivery. We would be happy to advise you with appropriate tables from our “Mobile Kitchen” range, mobile or stationary.
