Introduction

A spray dryer is an essential piece of equipment in various industries, particularly in the food and pharmaceutical sectors. It is used to produce dry powder from a liquid or slurry by rapidly drying with a hot gas. Understanding its purpose and functionality is key to optimizing production processes.

Purpose of a Spray Dryer

The primary purpose of a spray dryer is to convert liquid feed into dry powder. This is achieved by spraying the liquid into a hot drying medium, typically air. It offers several benefits, including the production of dry powder with uniform particle size and enhanced shelf life of the material. Spray dryers are widely used for preserving the characteristics of heat-sensitive materials.

The Spray Drying Process

The spray drying process involves feeding liquid material through an atomizer to create a fine mist. This mist comes in contact with hot air in a drying chamber, leading to evaporation of the liquid and formation of dry particles. The process parameters significantly affect the quality of the powder produced.

Key Parameters in Spray Drying

• Inlet Temperature: Typically ranges between 150°C to 220°C. Higher temperatures increase drying rate but can degrade heat-sensitive materials.
• Atomization Pressure: Ranges from 200 psi to 1000 psi. Affects particle size and uniformity.
• Feed Rate: Typically between 10 mL/min to 100 mL/min, impacting moisture content and drying efficiency.
• Airflow Rate: Should be sufficient to ensure complete drying, commonly set between 0.5 kg/hr and 5 kg/hr.
