Instant coffee is coffee powder that is produced by coffee beans that have been brewed at a higher ratio of coffee to water as compared to the regular coffee. In the production of instant coffee, there are two methods for drying coffee including spray drying and freeze-drying. In spray drying method, a spray device is used, in order to dry the coffee extract. The device transfers the hot air into the container and converts the product into fine powder.
