Commercial coffee roaster MI

A specialised range of roasters for natural coffee and torrefacto, a process where the green coffee bean is roasted with sugar, and sometimes other additives. No sugar or additives are used in the production of natural coffee. Coffee is roasted in a drum with swinging motion and unperforated sides to ensure effective air flow and airtightness during product processing. The roaster components and drum are manufactured from food grade stainless steel. TTA Series/MI range roasters are equipped with two independent coolers: one for natural coffee and the other for torrefacto. Roasting capacity of 420–1,700 kg coffee per hour. TTA Series/MI roasters can operate at half or full nominal load, at the same roasting temperature and producing the same roast profile. To achieve this, the PLC allows unlimited roast profiles that are automatically adjusted so they can be replicated exactly from one cycle to the next. Heat is mainly transmitted by convection during operating stages where no sugar is present, and by conduction when sugar is added. TTA Series/MI equipment operates at sugar levels of up to 33% in standard configuration. Capacity of 140–500 kg coffee per cycle. Single roasting drum. 420–1,700 kg torrefacto coffee roasted per hour Furnace with electronic progressive gas or diesel burner; low emissions Cylinder cooler with chaff-removing agitator paddles Circular cooler for torrefacto coffee Chaff collector PLC control panel and SIEMENS/AB colour touch screen Smoke afterburner with or without catalyst
