How to recognize the high quality sea salt and inferior sea salt?
From what respects analysis?
The answer:
sea salt quality good or bad From the following several aspects to identify:
Firstly on the appearance:
Good sea salt uniform grain appearance、drying、in quicksand shape、no obvious visible impurities.
Secondly,detection of soluble salt water velocity:the sea salt soluble in water and RO water。soluble speed fastly.the solution of water insoluble substance and all impurities,no precipitation.
Indicate:Sea salt dissolution time mainly depend on the quantity of salt dissolved.
For example: 1Kg sea salt dissolved 301 Fresh water,the process of agitation 3-5 minutes
completely dissolved as well.
1 tons sea salt dissolved 30 cubic water in the process of pump agitation 12 hours
completely dissolved as well.
The third aspect:Testing PH value Good sea salt PH value stability,Salinity normal ,
No phosphate and nitrate.
