PROCESS DESCRIPTION
Coffee beans are roasted, ground and then an extraction with water is carried out. The "coffee" produced in this way is first concentrated in a vacuum through removal of water, and the coffee concentrate is subsequently dried in a spray tower. For this purpose, hot air is introduced into the spray tower to withdraw the spray droplets of remaining water. The coffee powder thus obtained is packed with nitrogen as a protective gas and can then be stirred into hot water at any time and served as a finished coffee.
