Embodiment 1

[0027] A method for preparing snowflake-shaped edible salt from mineral salt: after dissolving mineral salt conforming to the grade of edible salt with water into mineral bittern with a sodium chloride content of 285 g / liter, transfer it to the original bittern pool to obtain clean bittern; The material pump pumps clean brine into the evaporation pool, keeps the brine liquid level 10 cm from the top of the pool, heats and evaporates, controls the evaporation temperature of saturated brine at 85°C, and controls the temperature of supplementary brine at 70°C, continuously adding brine to keep the liquid in the evaporation pool The surface is constant; during the evaporation process, every 10 hours, the solid salt on the surface of the evaporation pool is fished out, and brine is replenished immediately to keep the liquid level of the evaporation pool constant; , let the water seep out freely, and control the leaching time to more than 20 hours; transfer the damp salt after the le...

Embodiment 2

[0038] A method for preparing snowflake-shaped edible salt from mineral salt: adding water to dissolve mineral salt that meets the grade of edible salt into bittern with a sodium chloride content of 300 g / L, and then transferring it to the original bittern pool to obtain clean brine; The material pump pumps the clean brine into the evaporation pool, keeps the brine liquid level 15 cm from the top of the pool, heats and evaporates, the evaporation temperature of the saturated brine is controlled at 93°C, and the temperature of the supplementary brine is controlled at 78°C, and the brine needs to be continuously added to keep the liquid in the evaporation pool The surface is constant; during the evaporation process, every 8 hours, the solid salt on the surface of the evaporation pool is fished out, and brine is replenished immediately to keep the liquid level of the evaporation pool constant; , let the water seep out freely, and control the leaching time to more than 20 hours; tr...

Embodiment 3

[0042] A method for preparing snowflake-shaped edible salt by using bittern: after extracting bittern with a sodium chloride content of 300 g / L, it is input into the inclined plate settler, and a caustic soda solution with a mass percentage concentration of 25% is added to adjust the pH value If it is 8, add saturated food-grade calcium chloride solution that reacts excessively with sulfate radicals in the brine until the sulfate radical content in the brine is detected to be lower than 5 grams per liter, then input the brine into the sedimentation tank, add a certain amount of coagulant, and transfer to the sedimentation tank after precipitation. Put the clean brine into the original brine pool to obtain clean brine; put the clean brine into the evaporation pool through the feeding pump, keep the brine liquid level 10 cm from the top of the pool, heat and evaporate, control the evaporation temperature of saturated brine at 82 ℃, and control the temperature of supplementary brin...

Abstract

The invention relates to a method for preparing snowflake edible salt by using mineral salt or mineral brine, which comprises the steps of: heating in an evaporation tank, brine acquisition and treatment, evaporation for crystallization, salt fishing, shower control and drying. Since a raw material used for production is mirabilite mineral salt or mineral brine, the cost of the raw material is lower. Since the existing steam resources generated during mineral salt production can be fully used as steam used for production, a steam boiler is not required to be additionally built, the method is safe, environmental-friendly and energy-saving and the mass production in a mirabilite mineral salt area can be realized more easily. The snowflake edible salt does not contain any anticaking agent, looks like snowflakes, is white and crystal, has the characteristics of nature, high purity, low sodium content, looseness and delicious taste, is a new high-level seasoning product and is optimally suitable for cold vegetable dish in sauce, fried vegetables and soup. When the snowflake edible salt is used, the salt can be dissolved rapidly, the effect that dishes are easily salted can be achieved,the taste buds can be stimulated easily, the salty taste is increased, the acceptable daily intake of sodium ions is reduced and the body health is promoted when the salt is eaten for a long term.

Description

[0001] technical field [0002] The invention belongs to the field of condiments, in particular to a method for preparing snowflake-shaped edible salt by utilizing mineral salt or mineral bittern. [0003] Background technique [0004] Salt is the carrier of salty taste, and it is the most widely used condiment. It can be said that people can’t do without it in every meal, and with it as the basic taste, many flavor types can be prepared, known as the "king of all flavors". According to the resources used in production, salt can be divided into: sea salt, lake salt, well mine salt; according to the processing method, salt can be divided into: raw salt, refined salt, sun-dried fine salt, crushed washing salt; according to the use of salt, it can be divided into : Edible salt, food salt, industrial salt, multi-variety salt, etc. At present, common edible salts include iodized refined salt, iodized crushed washing salt, low-sodium salt, zinc-added salt, calcium-added salt, se...
