Spray Drying
Spray Drying is a common method used in the food industry to turn liquid products into powder form. Think of it like turning milk into powdered milk, or coffee into instant coffee. The process involves spraying a liquid food product into a hot chamber where it quickly turns into powder. Companies use this method because it helps make food products last longer, easier to transport, and simpler to store. This is especially important for products like powdered milk, instant coffee, powdered eggs, and some seasonings. Food companies often look for people who understand this process because it's widely used in large-scale food production.
