Bry-Air Dehumidifier helps increase throughput of Spray Drying of instant coffee at HUL by 20%

Spray drying is the preferred drying process because of its economy, short drying time, and usefulness when dealing with the fine, rounded particles it produces. Spray drying is a simple process of evaporating the water content of a concentrate using hot air in a closed chamber. Ground coffee beans are first mixed with water to form a concentrate with 75-85% water content and is pressed through an atomizer. As the droplets fall through hot air, water evaporates. Dry crystals of coffee fall to the bottom of the chamber and are collected there.
