Spray drying systems are widely used in food & beverage, pharmaceutical, chemical, and many other industries to produce fine and uniform micron size particles. Spray Dryer requires large quantities of hot air for drying. The quality of the final product (powder) is affected by the quality of inlet air entering the dryer.
The Spray Dryer mixes hot air with an atomized (sprayed) liquid stream in a drying chamber/atomizer which leads to evaporation and produces free-flowing dry powder. The inlet air has to be fresh and dry, free of contamination, and odourless. Since the ambient air changes throughout the year, the humid air can also enter the Spray Dryer, affecting its process.
Thus, the drying temperature and time inside the dryer needs close monitoring to restrict loss due to varying humidity levels.
These varying inlet conditions need to be monitored by an experienced operator to adjust the parameters for consistent output.
Due to high humidity, the powdered material tends to stick to the hopper conveyors and packing machine, leading to frequent breakdowns in the conveyor drive mechanism. This hinders the free flow of powders/granules, making many downstream operations (e.g., packaging, filtering, and handling) difficult and expensive.
Some of the common problems faced by powder manufacturers are:
Bry-Air has specially developed high-performance dehumidifiers for spray dryers for supplying controlled and consistent dehumidified air to the inlet point. This enables higher performance and output from spray dryers and improves the quality of the powder. Moreover, it reduces dependence on the operator for a constant adjustment of parameters on account of varying outside environment. It also reduces the energy consumption for heating the inlet air up to the required temperature. Dehumidifying the inlet air increases its temperature, as a result of which the heater has to do less work to heat up the air to the required temperature.
Moisture control for spray drying helps slurry to dry fast and allows smooth and free flow operations. Bry-Air Dehumidifier is recommended for humidity control as it continuously feeds dry air to the chamber, regardless of the ambient conditions, at a very low dew point. Bry-Air Desiccant Dehumidifier has successfully achieved the throughput in coffee powder spray drying unit. Our range of Dehumidifiers provide optimum drying at low temperatures for all powder. It can also be installed during the packaging and storage of powder to increase its shelf life.
High humidity can affect powder quality, cause powder to stick to spray dryer walls and conveyors, lead to frequent equipment breakdowns, extend drying cycle times, and reduce throughput. Spray drying humidity control helps maintain consistent drying conditions, minimise these issues, and improve overall process efficiency.
A dehumidifier for spray dryers supplies controlled, dry air to the inlet point, helping maintain consistent drying conditions regardless of changes in ambient humidity. This can improve powder quality and support higher spray dryer performance.
Excess moisture can prevent powders from flowing freely and may cause them to stick to equipment and packaging machinery. Effective moisture control for spray drying helps support smooth powder flow and consistent product quality.
Yes. Dehumidifying the inlet air can increase its temperature before heating, reducing the work required by the heater to reach the required drying temperature.
Bry-Air’s dehumidifiers for spray dryers are used across food powder applications such as coffee, spices and seasoning, fruit and vegetable concentrates, herbal food, milk, tea, and spray-dried eggs, as well as industrial applications like ceramic material, paint pigments, and chemicals, and pharmaceutical applications including antibiotics, encapsulation, enzymes, and vitamins. Bry-Air’s desiccant dehumidification has successfully supported throughput in coffee powder spray drying operations.
