What are the advantages and disadvantages of spray dryer?

The future development of spray dryer will develop and improve the spray dryer under the condition of in-depth study of dryer performance and material drying characteristics, and mastering the operating conditions of different materials. In addition, the basic trends in the development of dryers include chemical, high strength, high economy, and improved adaptability to raw materials and product quality. At the same time, the development of dryers also requires attention to energy conservation and comprehensive energy utilization, as well as the development of automatic control technology for dryers to ensure the realization of operating conditions.

Spray dryer is a device that can complete drying and granulation at the same time. It is suitable for drying heat sensitive materials. So, do you know the advantages and disadvantages of a dryer? Today, let me give you a detailed introduction.

1. Advantages of spray drying

(1) The spray drying system is applicable to the drying of heat sensitive and non heat sensitive materials, as well as the drying of aqueous solutions and organic solvent materials.

(2) The raw material liquid can be a solution, slurry, emulsion, paste or molten substance, or even filter cake, which can be processed.

(3) The spray drying operation has great flexibility. The spray capacity is several thousand grams to 200 tons per hour.

2. Disadvantages of spray drying

(1) The investment cost is relatively high.

(2) Spray drying is a convection dryer with low thermal efficiency, generally 30%~40%.

(3) The price of atomizers and powder recovery devices is relatively high.

(4) Low thermal efficiency and high heat consumption.
