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

Utilize rock salt or ore deposit stew in soy sauce to be equipped with the method for flakes edible salt
 
Technical field
The invention belongs to field of seasoning, particularly a kind of method of utilizing rock salt or ore deposit stew in soy sauce to be equipped with the flakes edible salt.
 
Background technology
Salt is the carrier of saline taste, is with the most use in the flavouring, we can say that people meal all can't do without it, and serve as to distinguish the flavor of basically with it, can modulate many flavor types, is known as " kings of hundred flavors ".Salt can be divided into by producing its used resource division: sea salt, lake salt, well mine salt; Salt is divided and can be divided into by processing method: crude salt, purified salt, Exposure to Sunlight fine salt, pulverizing washing salt; Salt is divided and can be divided into by purposes: edible salt, food are with salt, industrial salt, many kinds salt etc.At present, common edible salt has the iodinating and refining of adding salt, add that iodine is pulverized washing salt, Cardia Salt, adds zinc salt, adds calcium salt, added selenium salt, riboflavin nutritive salt, add molysite, spirulina salt compounded of iodine, salt in a healthy and balanced way, flakes edible salt etc.
The individual shape of flakes edible salt is like snowflake, and is bright during color and luster is white, has natural, pure, low sodium, loose, delicious characteristics, is high-grade seasoning good merchantable brand of new generation, and the optimum cold vegetable dish in sauce uses during with cooking burning soup.
The flakes edible salt of selling on the market is to change into bittern by sea salt, filters through multiple tracks technology again, and high temperature evaporation, crystallization forms, and its production technology is not seen public reported.
The composition of sea salt is sodium chloride, calcium sulfate, magnesium chloride, magnesium sulfate, calcium chloride; The composition of saltcake type rock salt or ore deposit halogen is sodium chloride and sodium sulphate; Document " sea lake salt and chemical industry " 25 volumes the 4th phase " chemical analysis of saline saturated bittern is to the influence of sodium chloride crystallization process " and " chemical industry and engineering " 31 volumes the 2nd phase " additive is to the influence of sodium chloride crystallization " have reported that all the different ions in the sodium chloride crystallization process all has crucial influence to its crystal habit; Therefore, saltcake type rock salt halogen or ore deposit stew in soy sauce are equipped with flakes edible salt technology and traditional sea salt halogen processing parameter should be visibly different.
Utilize saltcake type rock salt or ore deposit stew in soy sauce to be equipped with the flakes edible salt; Solved the technical barrier of well mine salt producing region production flakes edible salt; Can make full use of the existing steam resource in well mine salt producing region; Save production cost, and cost of material being also low than sea salt, is very favourable to the market that enlarges the flakes edible salt.
 
Summary of the invention
The technical problem that solves:The present invention seeks to provides a kind of method of utilizing rock salt or ore deposit stew in soy sauce to be equipped with the snowflake edible salt to domestic abundant saltcake type rock salt resource, and this method is produced snowflake edible salt graininess such as snowflake, hanged down sodium, the interpolation of loose, pure, delicious, no anticaking agent.
Technical scheme:The object of the invention is achieved through following technical scheme.
This preparation method who does not contain the snowflake edible salt of anticaking agent the steps include:
(1) heating evaporation pond: make up the pond body with the corrosion resisting alloy plate, the pond adopts the bottom to lay the jet chimney mode of heating for dark 0.8 ~ 1.0 meter, can guarantee that the heating-up temperature of bittern reaches 100 ℃ in the pond, and can be with evaporating temperature control within the specific limits;
(2) brine collection and processing: after the extraction sodium chloride content is the ore deposit halogen of 280 ~ 310 grams per liters; Be input in the inclined plate settler; Adding mass percent concentration and be 25% ~ 35% soda bath adjust pH is 8 ~ 9; Add with bittern in the excessive saturated food-grade calcium chloride liquid of sulfate radical reaction after being lower than 5 grams per liters bittern is imported sedimentation basin to detecting in the bittern sulfate radical content, add a certain amount of flocculation aid, post precipitation changes former halogen pond over to and obtains clean bittern (as adopting rock salt halogen; After then can rock salt being dissolved as the ore deposit halogen that sodium chloride content is 280 ~ 310 grams per liters, changing former halogen pond over to and obtain clean bittern);
(3) evaporative crystallization: through feeding pump the bittern of cleaning is squeezed in the evaporation tank, kept the brine solution identity distance from 10 ~ 20 centimetres on top, pond, heating evaporation; The saturated bittern evaporating temperature is controlled at 82 ~ 95 ℃; Additional brine temperature is controlled at 62 ~ 80 ℃, need continue with halogen, keeps the evaporation tank liquid level constant;
(4) fishing: in evaporation process, per 8 ~ 10 hours, the solid salt on evaporation tank surface is pulled out, and replenished bittern immediately, keep the evaporation tank liquid level constant;
(5) control is drenched: the control that the salt of pulling out is put in down the infiltration hole is drenched in the container, lets water freely ooze out, and the control pouring time was controlled at more than 20 hours;
(6) drying: the damp salt that will control after drenching is transferred to the drying bed inner drying;
(7) cooling packing: with dried salt, fully after the cooling, be distributed into inner wrapping with the proper packing thing after, warehouse-in, anti-pressure.
Beneficial effect:
Compared with prior art, the present invention has following advantage: produce raw materials used be saltcake type rock salt or ore deposit halogen, its cost of material is lower.Produce when required steam can make full use of rock salt production and have the steam resource now, need not to build in addition steam boiler, safety environment protecting energy saving is easier to accomplish scale production in saltcake type rock salt producing region.
Flakes edible salt of the present invention does not add any anticaking agent, and the outward appearance shape is like snowflake, and is bright during color and luster is white, has natural, pure, low sodium, loose, delicious characteristics, is high-grade seasoning good merchantable brand of new generation, and the optimum cold vegetable dish in sauce uses during with cooking burning soup.Can dissolve fast during use, can reach easily tasty effect of dish, stimulate taste bud easily, salty sense strengthens, and reduces the sodium ion intake, long-term edible help healthy.
