Coffee and tea processing — machinery overview
Coffee and tea are the world's most widely traded beverage commodities. The processing machinery required differs between the two crops. For roasted and ground coffee: green coffee bean reception and cleaning; destoning; optical sorting (colour sorter to remove defects); roasting (drum roasters, hot-air roasters, continuous rotary roasters); cooling; degassing (roasted coffee off-gasses CO₂ for days after roasting); grinding (for ground coffee); packing (degassing valves are essential on roasted whole-bean and pre-ground coffee packaging). For instant coffee: standard roasting; extraction (hot water percolation through roasted ground coffee); concentration; spray drying or freeze drying to produce instant coffee powder; agglomeration for granule texture; packing. For tea: fresh leaf reception; withering (moisture reduction); rolling (CTC — cut, tear, curl — or orthodox leaf rolling); fermentation/oxidation (for black tea); fixing/kill-green (for green tea); drying; grading and sorting; packing.
Frequently asked questions
What green coffee characteristics should I specify when buying a roaster?
Coffee roasters must be specified for the green bean input. Key parameters include: the range of green bean densities and moisture contents (different origins and processes produce beans with different bulk density and moisture); the batch size or continuous feed rate required; the roasting profile control requirements (artisan roasters prioritise precise, programmable temperature profiles; high-volume commodity roasters prioritise throughput consistency); the cooling method (air cooling is standard; water quench is used for some commodity roasting but is controversial in specialty coffee); and chaff collection and fire risk management (coffee roasting produces combustible chaff and VOC-rich exhaust — appropriate ventilation and spark arrestor systems are required). Do not make claims about flavour outcomes — these depend on many variables beyond the roaster.
