Abstract
The invention discloses a process for producing food-grade magnesium chloride. The process comprises the following steps: taking 100 grams of crude crystal magnesium chloride; mixing the crystal magnesium chloride with 35 milliliters of water; heating the mixture to between 80 and 100 DEG C so as to obtain saturated magnesium chloride solution; adding condensing agent to the saturated magnesium chloride solution; condensing and filtering the crystal to obtain magnesium chloride crystal; and evaporating and drying the magnesium chloride crystal to obtain food-grade magnesium chloride with a purity above 99 percent.
Description
Technical field
The present invention designs a kind of production technique of food-grade magnesium chloride
Background technology
Food-grade magnesium chloride is the important source material of foodstuff additive, the content requirement of its magnesium chloride reaches more than 99%, the most of manufacturing enterprise of China continues to use traditional magnesium chloride thermosol cold crystallization technology always at present, the heat energy consumption of this explained hereafter Repone K is big, product purity is not high, equipment corrosion is serious, so the cost height of product.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of production technique of food-grade magnesium chloride is provided.
Technical scheme of the present invention is: a kind of production technique of food-grade magnesium chloride, get magnesium chloride 100 grams of coarse crystal, add 35 milliliters in water and mix post-heating to 80 ℃～100 ℃, obtain the magnesium chloride saturated solution, add condensing agent and obtain the magnesium chloride crystal, obtain purity after the revaporization drying and be the food-grade magnesium chloride more than 99% through condensation, filtering for crystallizing.
The present invention has the following advantages: pollution-free, rate of recovery height has reduced product cost.
Specific embodiment
Embodiment: a kind of production technique of food-grade magnesium chloride, get magnesium chloride 100 grams of coarse crystal, add 35 milliliters in water and mix post-heating to 80 ℃～100 ℃, obtain the magnesium chloride saturated solution, add condensing agent and obtain the magnesium chloride crystal, obtain purity after the revaporization drying and be the food-grade magnesium chloride more than 99% through condensation, filtering for crystallizing.
