Abstract
The present invention is a kind of production technique of edible magnesium chloride, it is characterized in that, its step is as follows: get bittern and make raw material, add the biological enzyme discoloring agent and adsorbed 30-60 minute in bittern, filter with plate-and-frame filter press then, place settling bowl at 70-80 ℃ of following standing sedimentation 30-60 minute filtrate, get supernatant liquor and be heated to 120-130 ℃ of evaporation, mother liquor insulation postcooling crystallization in 30-90 minute, crystallization is tied sheet with flaker, pulverize, get product.The auxiliary separation and purification bittern of technology utilization biological enzyme of the present invention makes the food grade edible magnesium chloride, and its method is simple, and is workable, can remove heavy metal element, organism, impurity and insolubles effectively.
Description
Technical field
The present invention relates to the production technique of a kind of production technique of magnesium chloride, particularly a kind of edible magnesium chloride.
Background technology
China is maximum in the world magnesium chloride resource big country, and numerous inland brine lake magnesium chlorides, white clouds ore are not only arranged, and inexhaustible seawater magnesium chloride resource is arranged simultaneously.But because technical reason is not fully utilized so far as yet, products such as the magnesium oxide of developing, magnesium chloride are low owing to reason product specifications such as production technique, and added value is not high, and the comprehensive utilization of resources degree is insufficient.Edible magnesium chloride is the white plates body, and quality is hard, is easy to deliquescence, no-sundries.Edible magnesium chloride can be used for replenishing the necessary magnesium elements of human body, can be widely used in industries such as bean product making, medicine, textile auxiliary agent, foodstuff additive.Contain a large amount of harmful heavy metal element, organism, impurity and insolubles or the like in the technical grade magnesium chloride.Therefore, in the production process of edible magnesium chloride, how to remove the above-mentioned nuisance particularly important that seems.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, provides that a kind of technology is simple, workable, the production technique of the edible magnesium chloride of good product quality.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of production technique of edible magnesium chloride, be characterized in, its step is as follows: get bittern and make raw material, add the biological enzyme discoloring agent and adsorbed 30-60 minute in bittern, filter with plate-and-frame filter press then, place settling bowl at 70-80 ℃ of following standing sedimentation 30-60 minute filtrate, get supernatant liquor and be heated to 120-130 ℃ of evaporation, mother liquor insulation postcooling crystallization in 30-90 minute, crystallization is tied sheet with flaker, pulverize, get product.
In the production technology scheme of above-described edible magnesium chloride, the time that adding biological enzyme discoloring agent adsorbs in the bittern is preferably 45 minutes; Filtrate places settling bowl preferably 75 ℃ of following standing sedimentations 45 minutes; Supernatant liquor preferably is heated to 128 ℃ of evaporations, and mother liquor preferably is incubated postcooling crystallization in 45 minutes.
Biological enzyme discoloring agent described in the technical solution of the present invention can be disclosed any biological enzyme discoloring agent (flocculation agent) that the decolouring function is arranged in the prior art, it also can be commercially available any biological enzyme discoloring agent, for example: the green cyclisation worker in Henan company limited is on sale, CompanyAddress: road in the liberation of Henan Province's Jiaozuo City.
Compared with prior art, the auxiliary separation and purification bittern of technology utilization biological enzyme of the present invention makes the food grade edible magnesium chloride, and its method is simple, and is workable, can remove heavy metal element, organism, impurity and insolubles effectively.The technical indicator such as the following table of the edible magnesium chloride that makes with the inventive method:
