In the context of drying small spray dryers with high sugar content in Shanghai, it's crucial to address the unique challenges posed by organic solvents. These solvents are often flammable and explosive, necessitating the use of explosion-proof, closed systems. A laboratory-scale spray dryer is designed to operate within a closed drying system, filled with inert gases like nitrogen or argon. This setup prevents any contact between the solvent vapors and external oxygen, ensuring a safe production environment.
The small spray dryer operates using a nitrogen (or other inert gas) closed-loop circulation system. The entire system is sealed, and online monitoring of oxygen levels ensures safety. If the oxygen concentration reaches 2%, the system automatically stops and triggers an alarm. This makes it ideal for handling organic solvents, especially in lab settings where safety and ease of operation are paramount. It can manage flammable and toxic solvents effectively, thanks to the combination of nitrogen circulation and full solvent recovery, making it suitable for drying substances that are prone to oxidation.
Moreover, due to the low boiling point of organic solvents, this type of dryer allows for low-temperature drying, which is essential when dealing with heat-sensitive materials such as enzymes, live bacteria, or natural extracts. For instance, high-sugar content materials like fruit juice, herbal extracts, or natural product concentrates often have low melting points. When exposed to high temperatures, these materials tend to melt and stick to the walls of the dryer, resulting in poor-quality powders or granules. Similarly, enzyme preparations and live bacteria can easily lose their activity if exposed to excessive heat.
To address these issues, the inlet air temperature of the spray dryer can be adjusted downward, while maintaining an optimal outlet temperature to achieve better experimental results. The advantages of the small spray dryer are numerous:
1. **Fast Drying Speed**: The liquid is sprayed into fine droplets, increasing the surface area for rapid evaporation in a hot air stream.
2. **Low Droplet Temperature**: The drying process occurs at relatively low temperatures, preserving the quality of heat-sensitive materials. This minimizes damage such as protein denaturation, vitamin loss, or oxidation.
3. **Excellent Product Quality**: The final product retains a spherical shape, offering good dispersibility, fluidity, and solubility.
4. **Easy Operation and Control**: The process is modular and easy to manage, allowing for adjustments in particle size, bulk density, and moisture content.
5. **Environmental Protection**: The closed system prevents pollution and improves the working environment, especially when handling toxic or odorous materials.
6. **Scalability**: Suitable for continuous large-scale production, with integration options for post-processing equipment like coolers and wind power systems.
