Curing salt and preparation method thereof

Abstract

The invention discloses a curing salt and a preparation method thereof. The curing salt is composed of the following components in parts by weight: 90-100 parts of crude salt and 2*10-5-5*10-5 parts of potassium iodate in iodine content basis. The preparation method of the curing salt comprises the following steps: firstly, taking saturated brine in a deep well; secondly, adding NaOH to a brine pool to remove impurities in the saturated brine; thirdly, standing the saturated brine for clearness; and fourthly, adopting a vacuum salt production technology to improve solid-to-liquid ratio in an evaporating pot, wherein the ratio of the solid to the liquid is 3:15-19, and the working parameters of the brine in a primary efficient heating chamber are as follows: working pressure is 0.3-0.35Mpa, working temperature is 133-139 DEG C, and working time is 3-4 hours; and working parameters of the brine in a secondary efficient heating chamber are as follows: working pressure is 0.2+ / -0.05Mpa, working temperature is 120+ / -2 DEG C, and working time is 3-4 hours. The curing salt of the invention has the advantages of rough and even granules, difficult moisture absorption, easy coating, dispersity, low dissolution, strong seepage force, good salting effects, long refreshing time and the like. The preparation method of the curing salt is realized by selecting the reasonable technological parameters on the existing equipment of vacuum salt production, thereby having the advantages of low investment and good effects.

Description

technical field [0001] The present invention relates to salt and its preparation method, more specifically to a pickling salt and its preparation method. Background technique [0002] Pickles are a traditional Chinese delicacy, well-known at home and abroad. The pickling of pickles is a science, and the quality of salt used to pickle pickles determines the quality of pickles to a large extent. The larger the grain size of the salt, the crispier and better the taste of the pickled pickles. Nutrition guaranteed. Although ordinary edible salt can pickle pickles, there are some defects in ordinary edible salt as the salt for pickling pickles: the thickness of the edible salt is uneven, easy to moist, dissolve quickly, and the penetration is not strong, so the effect of pickling pickles is not good enough , The preservation time of pickles is not long. For this reason, the special pickling salt of pickling pickles remains to be explored, and the preparation method of the pick...
