Spray Drying of Citric acid
Spray Drying of Citric acid with the Mini Spray Dryer B-290
Citric acid is a weak organic acid that is commonly used as a preservative and flavoring agent in the food and beverage industry. Spray drying has been used to produce dry powders of citric acid, which can improve its handling and storage characteristics.
During the spray drying process, a citric acid solution is atomized into fine droplets and dried in a hot air stream to produce a dry powder. The resulting powder has good solubility, flowability, and low hygroscopicity, making it ideal for various applications.
Areas of spray drying of citric acid include the selection of appropriate raw materials, formulation development, process optimization, and product characterization. The optimal processing conditions such as temperature, flow rate, and inlet/outlet conditions are determined to optimize the particle size, solubility, and other physicochemical properties of the resulting powder.
Spray-dried citric acid powders are commonly used in various applications such as powdered beverages, confectionery products, and pharmaceuticals. The use of spray drying technology ensures consistent quality and high production efficiency, making it a preferred method for producing citric acid-based dry powders.
