Embodiment 1

[0031] Edible salt preparation process of the present invention

[0032] 1. Yantian production process

[0033] (1) Arrangement of drainage in Yantian

[0034] The mining area of ​​this test is selected in the eastern section of the Chaerhan Salt Lake, including the eastern section of the Chaerhan section and the Hobson section. The geographical coordinates are: east longitude: 95°23′22″-95°47′28″, north latitude: 36°41′39″-37°02′49″, with an area of ​​503.28km 2 . According to the function, the salt field is divided into three types: sodium-salt pool, carnallite pool, and adjustment pool. water arrangement.

[0035] (2) Irrigation of brine: the raw brine collected through the brine mining channel is transported to the sodium salt pond for solar evaporation; as much brine as possible is collected for irrigation; the brine is evaporated in the salt field, and the salt precipitation sequence is NaCl→ NaCl+KCl MgCl 2 ·6H 2 O→MgCl 2 ·6H 2 O (see attached figure 1 ).

Embodiment 2

[0080] A method for extracting nutritional green edible salt from a salt lake mining area, the specific steps comprising the following steps:

[0081] Step 1, Yantian production process:

[0082] S1, Salt pan drainage layout: Salt pan is divided into three types according to functions: sodium salt pool, carnallite pool, and regulating pool. The direction of the carnallite pool is arranged for water flow;

[0083] S2, brine irrigation: the raw brine collected through the brine mining channel is transported to the sodium salt pool through the brine delivery channel for solar evaporation; collect as much brine as possible to irrigate the brine;

[0084] S3, guide brine: according to the analysis results of the actual sampling brine components and the Baume degree measured on site, use the test analysis results and phase diagram analysis to conduct brine guide; specifically, when the brine is guided from the sodium salt pool to the adjustment pool, Controlled at 320-32.50Be', wh...

Abstract

The invention relates to the technical field of edible salt extraction, in particular to nutritional type green edible salt extracted from salt lake mining areas and an extraction method thereof. The method specifically comprises the steps of salt pan production, a test for removing trace heavy metals in a solid sample, a test for improving the dissolution rate of the solid sample and a test for changing components of the edible salt solid sample. According to the method, in the salt pan sampling and washing work, used equipment is light and handy, and the operation is relatively simple; physical washing is adopted and does not pollute brine in the salt pan, and washing tail liquid is discharged into the salt pan and does not affect carnallite production in the salt pan; the whiteness, granularity, sodium chloride, water-insoluble substances, lead, arsenic, fluorine, barium and other related hygienic and chemical indexes after washing completely meet the national edible salt standard; trace heavy metals in the solid sample are further reduced by an alkali washing method; the solid sample can be dissolved within about 6 seconds at the fastest rate; and in addition, operations such as road construction, drilling, groove exploration, pit exploration, well exploration and the like which damage the soil surface do not exist in the test process.

Description

technical field [0001] The invention relates to the technical field of edible salt extraction, in particular to a nutritional green edible salt extracted from a salt lake mining area and an extraction method thereof. Background technique [0002] Edible salt is an indispensable condiment in people's daily life, and it is also one of the essential nutrients to maintain the normal excitement of human muscles and brain nerves, maintain the balance of acid-base and electrolytes in the human body, and promote the normal metabolism of the human body. [0003] Edible salt can be divided into sea salt, lake salt, and mine salt according to the source of raw materials; refined salt, sun-dried salt, and crushed washing salt according to the processing method; common table salt and multi-variety table salt according to the function. Different sources and different processing methods have led to the possibility that edible salt products may be affected by pollutants from water bodies, s...
