Embodiment 1

[0035] Example 1 : Preparation of Vegetable Salt Containing Sea Salt and Rhodiola Rosea Extract

[0036] step 1 , brine to remove heavy metals

[0037] (1) Precipitation filtration

[0038] Filtration: Take coastal brine, the content of tungsten ions is 26mg / L, the content of lead ions is 20mg / L, and the content of nickel ions is 22mg / L. Put the brine into the sedimentation tank and settle for 7 hours.

[0039] Mechanical filtration: the brine from which heavy metal ions have been removed is mechanically filtered to remove large solid impurities and mechanical impurities; the turbidity of the brine after filtration is 2NTU.

[0040] Nanofiltration: The mechanically filtered brine is subjected to nanofiltration treatment. The nanofiltration temperature should be controlled at 22°C and the pressure should be controlled at 0.6MPa.

[0041] A reducing agent is added to the nanofiltration process, and the reducing agent used is sodium sulfite, and the amount of the redu...

Abstract

The invention provides sea salt and rhodiolarosea extract containing plant salt. The sea salt and rhodiolarosea extract containing plant salt comprises sea salt and a rhodiolarosea extract. In the sea salt and rhodiolarosea extract containing plant salt, the total content of rosavin is 0.3%-2%, and the content of rhodioloside is 0.25%-1.5%. The invention also provides a method for preparing the plant salt by using a preheating enrichment crystallization process. The method comprises the step of removing heavy metals with brine; the step of removing heavy metals with brine includes the step of removing the heavy metals with an aeration method; in the step of removing the heavy metals with the aeration method, the brine is aerated by using ozone, and the aeration time lasts for 20-40 min. By using the special process provided by the invention, a prepared bio-adsorbent is enabled to have good removal effects on heavy metal ions, and the removal effect of the bio-adsorbent on lead ions is 10%.

Description

technical field [0001] The invention relates to a plant salt containing sea salt and rhodiola rosea extract and a method for preparing the plant salt by adopting a preheating concentration crystallization process, belonging to the technical field of plant salt. Background technique [0002] Plant salt refers to a balanced salt that is extracted from plant organisms, uses purely physical processes and techniques, meets low-sodium salt and various mineral trace element groups, and the ratio of various elements meets the requirements of the human body. It is a new type of edible salt that can promote function regulation, metabolism and health. [0003] The biological activity of plant salt depends on the selection and combination of raw plant species and the amount of inorganic salt they contain, the content and ratio of elements, and the biologically active components related to plants; People with a sodium diet, and people with metabolic disorders, functional decline and fun...
