A Laboratory spray dryer uses a liquid stream, in this operation, there is a separation between the solvent or suspension as solid and the solvent to vapor.The solid is taken in a drum or cyclone. Solids form as moisture quickly leaves the droplets.
Spray dryers can dry a product very quickly compared to other methods of drying. They also turn a solution into a dried powder in a single step, which simplifies the process.
Spray drying is used to produce Amorphous Solid Dispensation in the manufacture of medicines.
1)For high carbohydrate-containing products (e.g. fruit juice, herbal medicine or natural product
extracts) or thermo-sensitive materials - Use models SD-18 ,SD-20 ,SD-8
2)For materials with an organic solvent or oxidizable materials— Use models SD-51, SD-15A, SD-8
3) For Conventional materials - Use our mini-spray dryer model SD-15

What is Spray Dryer?
Spray drying is a method of producing dry powder from a liquid or suspension mixture, by rapid and gentle drying of the liquid by spraying it in hot air.Laboratory spray dryers are specialized equipment designed to convert liquid substances into powder form through a process called spray drying. This method is widely used in industries such as pharmaceuticals, food and beverages, and chemicals.
Uses of spray drying
Spray drying is Useful for making powders in the food and beverage industry, extracts, food additives, pharmaceuticals and chemicals, cosmetics and detergents, polymers and resins, ceramics and special materials.In the pharmaceutical industry, pharmaceutical drugs and vaccines are dried.
Applications in Research and Development
Laboratory spray dryers play a pivotal role in advancing research and development efforts across various industries.
A. Pharmaceutical Industry
In pharmaceuticals, these dryers are crucial for creating easily dispersible powders from liquid drug formulations.
B. Food and Beverage Industry
The food and beverage industry utilizes laboratory spray dryers to produce powdered flavors, nutrients, and other essential ingredients.
C. Chemical Industry
In the chemical industry, these dryers are employed to process various chemical solutions into manageable powders.
How Does a Laboratory Spray Dryer Work?
The process is fascinatingly simple yet highly effective. Here’s how it works:
Liquid Feed: A solution is fed into the spray dryer through a pump.
Atomization: The liquid is atomized into tiny droplets via a nozzle.
Hot Air Introduction: Hot air is introduced into the drying chamber.
Drying: As the droplets mix with the hot air, moisture evaporates.
Powder Collection: The dry particles are collected in a separator.
This method ensures even drying, maintaining the integrity of sensitive materials.
How to influence particle size : The higher the solids content of the material, the larger the particle size;
the larger the nozzle, the larger the particle size;
the higher the atomizing pressure, the smaller the particle size.
