Production of coffee• PLANTINGA coffee bean is actually a seed. Since coffee production is seasonal, traditional sun drying is quite tough. After removal of the pulp, the green coffee beans are dried, cleaned and packed – typically in 60 kg bags – and stored until they can be roasted and, if required, decaffeinated. The physical-chemical evaluations of the drying and storage conditions showed that washed coffee presents better quality when compared to the product in its natural form. The study revealed that the quality of the coffee was unaltered over the temperature range studied. The coffee … Roasting coffee beans to perfection is an art as much as a science, since they may react differently to the roasting process, depending on the soil and weather conditions in which they were grown and the processing method used. Decaffeination is the process of extracting caffeine from green coffee beans prior to roasting. Brazil is the largest coffee producer in the world, with an average production of 2.5 million tons per year. The final link in the flavour chain is roasting. production process.
