A Spray Type Fruit Juice Dryer (specifically for banana and other fruits) is a high-tech machine that converts liquid pulp or juice into a fine, shelf-stable powder.  For banana powder, this is the preferred method because it preserves the fruit's nutrients and flavor better than drum drying.

1. The Banana & Fruit Juice Drying Process

1. Preparation: Ripe bananas are peeled and mashed into a smooth pulp. Fruit juices are filtered to remove large fibers.
2. Carrier Mixing: Fruits like banana and pineapple are naturally "sticky" due to high sugar content. A carrier (usually Maltodextrin, 10–20%) is mixed into the liquid to ensure the powder doesn't stick to the machine walls.
3. Atomization: The liquid is fed into the dryer and turned into a fine mist using either a Rotary Disc Atomizer (better for thick pulps like banana) or a Pressure Nozzle.
4. Instant Drying: These tiny droplets meet a spiral of hot air 160 C  to 180 C The water evaporates in seconds, leaving behind solid particles.
5. Collection: The powder falls through a Cyclone Separator where it is cooled and collected in bags.

Critical Tip for Banana Powder

If you are specifically making Banana Powder, ensure your dryer has a Dehumidified Air System at the collection point. Banana powder is extremely "hygroscopic" (it absorbs moisture from the air instantly). If your packing room isn't dry, the powder will turn into a hard block within minutes.
