Instant coffee comes in three different forms, freeze dried, spray dried and liquid concentrate. Although the initial brewing process is the same for all methods they vary greatly with the methods used to produce the final coffee product. Typically the coffee beans chosen for instant coffee production are from the lower end of the quality scale, since many of the subtle flavours and aromas of the more expensive types are lost in the production process. Freeze dried coffee was discussed in a different article, so here we concentrate on the production of Spray Dried Coffee.

Stage One – This stage involves the production of large quantities of freshly brewed coffee using industrial bulk brewers. Freshly ground coffee is put into contact with hot water in industrial brewers until the desired degree of extraction has occurred. The process can either be the drip filter method that many use in the home or an industrial version of the coffee percolator. Much waste product is produced in the initial brewing chambers in the form of used coffee grounds. However these days they are recycled for use in animal foods, used as organic fuels or proccessed as compost. Stage Two – The resulting coffee liquor liquid is then concentrated through an evaporation process where some of the volatile aroma components are removed and stored to be returned later prior to packing.

This stage produces a thick more viscous coffee liquid that is then ready for the next stage in the making of spray dried instant coffee. Stage Three – The concentrated liquid coffee is then sent to the spray-drying tower where it is turned into powder. This is achieved pumping the coffee concentrate through an atomizer where it is broken into small droplets. The falling droplets lose their water content rapidly as they come into contact with the drying gases. They are suspended in the drying air and typically seperated by centrifugal action.
Additional Information

Spray-dried liquid coffee extract is used to make spray-dried coffee, which uses current technology to maintain the rich coffee flavour. Coffee powder that has been spray-dried is extensively used around the world and is easy to use on a routine basis. Spray-drying solid solvents preserve their greatest constituents.
