Problems solved by technology

If iodized salt is produced, an iodized device for dripping iodine solution is provided before entering the drying bed, but long-term production practice has proved that the iodine solution attached to the wet salt boils in the drying bed. It is volatile at ℃, and it will make the edible salt "green" and affect the quality of the edible salt

Embodiment Construction

[0034] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0035] A green standard salt preparation process has the following steps:

[0036] One), carry out brine mining in the mine, and store in the original brine barrel;

[0037] 2), purify and pre-treat the original halogen in the original brine barrel, and store in the refined brine barrel after removing calcium and magnesium ions;

[0038] 3) Use evaporative salt-making equipment to evaporate and crystallize the purified brine in the brine barrel, extract the salt slurry, and use the condensed water produced by the evaporative salt-making equipment to mine brine;

[0039] 4) The salt slurry is discharged from the salt leg of the evaporative salt making equipme...

Abstract

The invention relates to a preparation process and a special device for salt with green food label. The device comprises mine brine mining equipment, an original brine barrel, a brine pretreatment system, a refined brine barrel and evaporation salt-making equipment, which are sequentially arranged. A salt slurry outlet of the evaporation salt-making equipment is sequentially provided with a centrifugal machine and a drying device, while a condensed water outlet of the evaporation salt-making equipment is communicated with the mine brine mining equipment; a refined brine countercurrent device for refined brine countercurrent backwashing salt slurry is arranged between the evaporation salt-making equipment and the centrifugal machine; and an outlet of the drying device is provided with a sieving machine, and a sieving machine outlet is provided with packaging equipment. The salt is prevented from caking by physical molecular structure of sodium chloride through improving production process and production equipment, optimizing process indexes and obviating potassium ferrocyanide and other anticaking agent. Qualification rate of iodized salt manufactured with the invention is 100%, the utilization rate of potassium iodate is 95%, the iodide content of finished product salt is steady and reliable; and the fluctuation range is within 5 mg / L.

Description

technical field [0001] The invention relates to the technical field of edible salt preparation equipment, in particular to a green-label salt preparation process and special equipment. Background technique [0002] Edible salt is an indispensable substance in people's daily life, and it is also an important industrial raw material. In modern times, the production and sales of salt are one of the important indicators to measure the degree of industrialization of a country. [0003] Edible salt must be produced from natural seawater, salt lake brine and natural salt mines. Any chemical by-product sodium chloride cannot be used as edible salt. Edible salt can be divided into refined salt, crushed washing salt, and solar salt according to its production and processing methods. [0004] In the national standard of edible salt in my country, there is only one index of anti-solidification agent that is allowed to be used, which is the addition of potassium ferrocyanide in the pr...
