Question:
For a spray drying plant, which of the following design layout is most suitable ?
For a spray drying plant, which of the following design layout is most suitable ?
Show Hint
Because spray drying towers rely on a vertical gravity fall of droplets, the plant building must be designed as a multi-level structure, often reaching heights of \(4\) to \(6\) storeys.
Updated On: Jul 21, 2026
- Zero level
- Single level
- Two level
- Multi level

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
The design and layout of a dairy processing building depend on the height, gravity flow, and spatial requirements of the equipment.
Step 2: Detailed Explanation:
A spray dryer consists of a tall, vertical drying chamber, often \(15\) to \(30\) meters in height.
This vertical design is necessary because the atomized milk droplets must fall through the hot air stream by gravity, drying completely before they reach the bottom of the chamber.
Additionally, the plant requires other auxiliary equipment installed at different heights:
- High-pressure feed pumps and feed pre-heaters are located near the top.
- Cyclones, bag filters, and wet scrubbers are positioned at intermediate levels.
- Fluidized bed dryers, powder packaging systems, and transport conveyors are situated at the bottom.
To accommodate this vertical equipment and facilitate gravity flow, a multi-level (multi-storey) structural design layout is essential.
Single-level or two-level designs are not tall enough to house a commercial spray drying tower.
Step 3: Final Answer:
A Multi level design layout is most suitable for a spray drying plant.
