Spray drying is not only flexible to be use in different products, but it also provides a lot of advantages. It is a process involving both particle formation and drying. It has high performance due to low resistance time, turn a solution or slurry into a dried powder in a single step which can be very advantageous for process simplification and profit maximization. The water evaporation cools down the droplets, thus allowing the use of a high drying temperature.
It provides an excellent presentation of the product, continuous process, constantly monitored and controlled and installation operated by only one worker. It has also a full automation, a 24 hour day operation and can produce a homogenous product. Actually, spray dryer tower is used to convert a liquid solution or suspension to a dry, free flowing powder.
Another advantage is its quality control. The method produces powder of the overall quality and controllable particle size. Other characteristics are also manipulated during the process including a degree of crystallinity, bulk density and residual solvent levels. Being able to control the parameters also make the entire method desirable for industries like pharmaceuticals, where an absorption of the drug depends on the particle size.
The selection and operation of the atomizer is of extreme importance in achieving an optimum production and operation of top quality powders. There are actually many reasons why the tool is essential for any given application. The dry particle sizes can also be controlled by certain atomization and the designs of the hot gas inlet. Once the process is done properly the spray dryer techniques and designs can also increase the yields of products that require classification.
The shape of the spray dried particles is also spherical, which can provide for fluid like flow properties. This makes a lot of downstream operations such as pressing, packaging, handling and filtering easier at lesser cost. It also produces homogenous products for multiple solutions. Most of the particles will be of the same composition.
The mass and heat are transferred during the procedure and may occur in the air and vapor films surrounding the droplets. The vapor protects and keep the particles at its saturation temperature. Every surface area can also be produced by the atomization and enables a short gas resident depending on its application which allow the use of the process without any thermal degradation.
To understand more the process, one example is the milk. In many countries around the globe, refrigeration is not a normal idea for many regions, like in Europe. The ability to keep huge quality of products including milk is also limited. So, powdered milk can only be used if needed and may increase its shelf life.
Most of the fat soluble vitamins in most powdered nutrient premix can also be done by using the tool and process of the nutrients and adding them to the premix. Most of these dryers also give an immediate method for drying product than other methods.
Recent research is not recommending that the use of these techniques may be a good alternative method for crystallization during the process since the temperature effects may be significant depending on residence times.
