Commercial coffee roaster NM

A specialised range of roasters for torrefacto coffee, a process where the green coffee bean is roasted with sugar, and sometimes other additives. 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. The torrefacto coffee cooler has a single cooling cylinder. Roasting capacity of 180–1,700 kg coffee per hour. TTA Series/NM 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/NM equipment operates with sugar levels of up to 33% in standard configuration and 75% for special technical characteristics. Capacity of 60–560 kg coffee per cycle. Single roasting drum. 180–1,700 kg torrefacto coffee roasted per hour Furnace with electronic progressive gas or diesel burner; low emissions Cylinder cooler with chaff-removing agitator paddles Chaff collector PLC control panel and SIEMENS/AB colour touch screen Smoke afterburner with or without catalyst The TTA Series/NM range is designed to almost exclusively roast torrefacto coffee, with various levels of added sugar and the potential to use other additives. Roast time in TTA Series/NM range roasters is 20–35 minutes.
