Spray dryers are industrial drying systems that combine atomization and heating processes to dry liquid materialsn into powder quickly.
Technological innovation: fast drying speed. The feed liquid can evaporate 95% - 98% of water in a flash in the high temperature airflow, and the drying time is only a few seconds. Spray drying is characterized by fast heat transfer, rapid water evaporation, and short drying time. Besides, the product has good quality, crisp texture, and good solubility, which can improve the dissolution rate of some preparations and is suitable for thermosensitive drugs. In addition, spray drying can also be used to prepare microcapsules.
The parallel flow spray drying can make the droplets flow in the same direction as the hot air. Although the temperature of the hot air is high, the hot air enters the drying room and immediately contacts with the spray droplets. The indoor temperature drops sharply, while the wet bulb temperature of the material basically remains unchanged, so it is also suitable for drying thermosensitive materials.
Spray drying is a method of systematic technology applied to powder material drying. After atomizing the diluent in the drying chamber, the moisture will vaporize rapidly in the contact with hot air to obtain the dry product. This method can directly dry the solution and emulsion into powder or granular products without evaporation and crushing.
Drying characteristics: the drying process is very fast;
The fluidity can be directly dried into powder;
The drying conditions and product quality standards could be easily changed and adjusted;
Due to instantaneous evaporation, the selection of equipment and materials is not strict;
The drying room has a certain negative pressure, which ensures the sanitary conditions in production, avoids dust flying in the workshop, and improves the product purity; High production efficiency and few operators.
Advantages of spray drying over other industrial drying equipment include controlled particle size, enhanced flow characteristics of the dried solids, evaporative cooling, reduced corrosion and short residence times.
The industrial drying equipment market is now getting more competitive and there are numerous spray dryer manufacturers, so customers are likely to experience headaches when choosing a supplier. This blog provides an overview of the top 7 spray dryer manufacturers in 2022 and beyond, in order to help you make a better choice.
You are now more familiar with some of the popular spray dryer manufacturers around the world, but you must still research each company, compare their products, ask the right questions, and choose the one that best suits you and your needs.
