Spray Drying Technique in depth 

Exact temperature I won’t be able to tell but just keep in mind the temperature should be below the degradation temperature of the molecule.

No sorry I don’t

Molasses are viscous right? If it is sprayable than it can be dried.

Yes we can but spray drying is an expensive technique. You should consider the business prospect of your product also.

Both can be simple air. Filtered air heated to a certain temperature. Compressed air.

Thanks for the question. Steam is water converted into vapours. When you cool it, it forms water droplets. Whereas hot air is just air with no water content. In spray drying we want to dry our product completely to remove moisture from it. So, we use electrically heated air in spray drying.

@@pharmacyindepth9715 thank you so much.....i am not a pharmaceutical student....i am CA student...but i always interested in food and pharmaceutical industry....

Well that depends on the product you are drying. It should be sufficient enough to dry the solvent of a droplet before it touches the wall of drying chamber.

@@pharmacyindepth9715 I am looking for maximum temperature of 40 Celsius. This is for spirulina micro algae drying.

If the solvent evaporates at that temperature than you can do it. Keep the feeder rpm low.

The particle hardness will depend on- 1. Spray pump rpm 2. Volatility of the solvent 3. Temperature of the drying chamber

Can you explain in what way it each points affects the hardness of particle

Because more the temperature, more will be the evaporation rate of your particles. Hence more moisture it will give.

@@pharmacyindepth9715 im going to need you to explain that with an analogy or something

No I don’t have.

that’s really rude
