If it is large quantities just leaving the salt well spread out in the sun for a few days will suffice.

If the laboratory scale brings the salt into the oven for 2 hours, it will work or at 65-75 ° C in the oven for 1 to 2 days.

To keep the salt dry put some rice in the jar it will absorb the ambient humidity

Yes, you can use a oven at 110ºC, during 24h for exemple!

According to my opinion you should dry them till the weight is constant.

 Oven 24 hr at 70C

Dear Colleague, 

Thanks a lot for this question. We can several several methods for drying salt, such as: hot air, oven, Infra red radiation, drying by conduction. We can alos the isotherm of adsorption of water on the surface of the salt. About the necessary time of drying, i think that the salt cannot change its quality even the time of drying is so long.

with my best regards!

Spray dryer can be used.

Dry everything in a drying chamber (dryer) at 100-110ºC for 24 hours, it will be more than enough.

How can design a flash dryer?

Would you please give me a plan?
