Buy Spray Dryer: Things You Need To Know
Choosing a suitable small spray dryer is very critical for the later use of the laboratory. The author summarizes seven points that need attention when buy spray dryer.
Point 1: buy spray dryer considering laboratory space and materials’ amount
Considering your own laboratory space and the amount of materials that may need to be processed when buy spray dryer. Therefore, you could have a basic idea of what the handling capacity of the spray dryer should be, such as Hawach’ pilot scale spray dryer: CSD-3L with a handling capacity of 1.5-3L/H, and CSD-5L, 0.05-5L/H, etc.
Point 2: buy spray dryer based on your purpose, for teaching or scientific research
If it is for teaching, try to use a high borosilicate glass drying room to facilitate students to observe the experimental process. If it is for scientific research, glass or stainless steel can both be used. The mature process requires a more-durable stainless-steel spray dryer. And multiple materials requires the adjustment of process, which can be achieved by adding components of glass. Hawach has spray dryers with high borosilicate glass drying chamber and stainless steel coating, which is a perfect match for generally small tests and corrosion-resistant environments.
Point 3: buy spray dryer considering safety
If the ready-to-process material is an organic one, you should consider spray dryers with an inert gas circulation system, which has relatively-low oxygen concentration. The solvent can be recycled on the spot without any hidden danger.
Point 4: buy spray dryer according to the materials that may be used
If it is a sugar-containing material, such as Chinese medicine, it is best to choose a dryer that can provide low temperature, such as an inlet air temperature of 110 ° C, so that the material will not stick to the wall; if it is ceramic or catalyst, it is best to buy spray dryers by using which materials will have a wide particle size range (1-100um) after drying. For heat-sensitive materials such as probiotic enzymes, a vacuum spray dryer is recommended for its relatively-low working temperature.
Point 4: buy spray dryer that can be equipped with many other components
If your material is not sure, it is recommended to buy spray dryer that can be equipped with many other components for future use. For example, you can purchase a nitrogen circulation system to form an organic solvent spray dryer, and vacuum module to upgrade to a vacuum low-temperature spray dryer.
Different materials require different spray dryer. Buying a suitable spray dryer can accelerate your testing or researching process, and ensure you good results as well. When you decide to buy spray dryer, taking your laboratory space, material amount as well as material’s features into consideration. You can list the materials that you may use in future scientific research, whether it is an aqueous solution or an organic solvent, a relatively single material, or many types of materials. And you are also welcomed to communicate with our sales workers to decide which spray dryer is up to your specific needs.
