Method for producing liquid edible salt through brine extraction of well and rock salt and liquid edible salt

Abstract

The invention relates to a method for producing liquid edible salt through brine extraction of well and rock salt. The method comprises the steps: (1), injecting fresh water in a mine for brine extraction to obtain brine; (2), purifying the brine obtained in the step (1) to remove impurities; (3), evaporating and concentrating liquid salt obtained in the step (2) to ensure that the concentration of sodium chloride reaches 20-36 wt percent; (4), adding the concentrated liquid salt of sodium chloride in the step (3) in potassium iodate or algae iodate, uniformly mixing and stirring; and (5), sub-packaging the liquid edible salt obtained in the step (4). According to the method, the liquid salt is directly prepared through the brine extraction of well and rock salt without being evaporated and concentrated into solids, thus energy can be saved. The salt is loaded in a plastic container which is marked with scales and provided with an extruding nozzle or provided with an extruding nozzle with fixed spraying amount every time, thus the salt adding amount can be precisely controlled, and the condition that the food is too light or too salty due to excessive salt or insufficient salt is prevented.

Description

technical field [0001] The invention relates to a method for producing liquid edible salt by extracting brine from mine salt and the liquid edible salt obtained by the method. Background technique [0002] Salt is an essential trace element for the human body, and it is also the first of all flavors. It is closely related to people's daily life. Salt is the carrier of salty taste and is the most used condiment. It is the basic flavor and can be prepared into many flavor types, known as the "King of Hundred Flavors". According to the resources used in production, salt can be divided into: sea salt, lake salt, well mine salt; according to the processing method, salt can be divided into: raw salt, refined salt, sun-dried fine salt, crushed washing salt; according to the use of salt, it can be divided into : Edible salt, food salt, industrial salt, multi-variety salt, etc. At present, common edible salts include iodized refined salt, iodized crushed washing salt, low-sodium sa...

Problems solved by technology

[0007] The disadvantage of the above-mentioned invention is that the first patent is to dissolve solid salt in drinking water, and then add potassium iodate or potassium iodide solution. When adding potassium iodate or potassium iodide solution, the ratio of element iodine to salt is different It is easy to control, and the solid salt that has been evaporated and dried is restored to liquid salt, which is not conducive to energy saving

The second patent is the extraction of liquid edible salt from seawater, the process is relatively complicated
