Embodiment 1

[0047] A. Dissolve edible potassium chloride in water to form a saturated solution, evaporate and concentrate at 105°C for a period of time, and then add potassium chloride seed crystals with a crystal size of 0.6mm in proportion to 100% of the potassium chloride mass in the saturated solution , Forming a thick slurry;

[0048] B. Place the concentrated slurry obtained in step A in an ordinary crystallization tank to cool to 35°C for crystallization for 5 hours, and then separate and dry the crystals obtained in the crystallization tank to obtain the potassium chloride product, Example 1.

Embodiment 2

[0050] A. Dissolve food grade potassium chloride in water to form a saturated solution, evaporate and concentrate at 100°C for a period of time, and then add potassium chloride seed crystals with a crystal size of 0.6mm in proportion to 100% of the potassium chloride mass in the saturated solution , Forming a thick slurry;

[0051] B. Place the concentrated slurry obtained in step A in an ordinary crystallization tank to cool to 35°C for crystallization for 60 minutes, and then separate and dry the crystals obtained in the crystallization tank to obtain the potassium chloride product, Example 2.

Embodiment 3

[0053] A. Dissolve edible potassium chloride in water to form a saturated solution, evaporate and concentrate at 100°C for a period of time, and then add potassium chloride seed crystals with a crystal size of 0.5 mm in proportion to 60% of the potassium chloride mass in the saturated solution , Forming a thick slurry;

[0054] B. Place the concentrated slurry obtained in step A in an ordinary crystallization tank to cool to 30°C for crystallization for 30 minutes, and then separate and dry the crystals obtained in the crystallization tank to obtain the potassium chloride product (Example 3).

Abstract

The invention discloses a salt-compound product and a preparation method thereof and concretely relates to an edible potassium-chloride product and a preparation method thereof; the mass of potassium-chloride crystal particles with the granularity of more than 0.5mm in the potassium-chloride product accounts for more than 80 percent of that of the potassium-chloride product; and the average granularity of the crystal particles in the potassium-chloride product disclosed in the invention is larger, so that when potassium chloride is used for preparing edible salt, particularly low-sodium salt, the potassium-chloride crystal particles and sodium-chloride crystal particles in the edible salt are more uniformly distributed, and furthermore, the intaking amount of the potassium chloride is more uniform when people use the edible salt each time.

Description

Technical field [0001] The invention relates to a salt compound product and a preparation method thereof, in particular to an edible potassium chloride product and a preparation method thereof. Background technique [0002] Potassium chloride is an inorganic salt compound whose molecular formula is KCl, which is composed of potassium ions and chloride ions; potassium chloride can be used as an industrial raw material for the production of various potassium salts such as potassium hydroxide and potassium sulfate , Potassium nitrate and potassium chlorate, etc.; potassium chloride can also be used as a daily necessities, used as an auxiliary ingredient in low-sodium salt or mineral water, so as to provide a certain amount of potassium ions for the human body; potassium chloride can also be used to prepare medicine Industrial diuretics and drugs for preventing and treating potassium deficiency. [0003] Most of the potassium chloride crystal particles in the existing potassium chlori...
