Problems solved by technology

Due to the influence of conventional ideas and standards, it is very unreasonable to further remove calcium, magnesium, potassium, iron, copper, zinc and other metal ions as impurities in the scrubber. At the same time, because the washing process makes A large amount of crystallized salt is dissolved in brine and washed away, causing great waste
Increase energy consumption, consume water resources in vain, poor product quality, unfavorable personal health, high cost, and low economic benefit

Embodiment

[0045] The preparation method of the refined natural nutrient salt of the present invention uses the concentrated seawater as the basic raw material, imports the beach-dried seawater into the brine storage pool, uses the sun to make it into nearly saturated brine, and then passes it into a multi-layer sand filter for filtration. The brine from which solid impurities such as sediment have been removed is the basic raw material. The brine pre-stored in the brine storage tank is used as the basic raw material. When preparing materials for production, the basic raw materials are first put into the evaporation tank. After the evaporation starts, the basic raw materials are preheated by the preheater and then enter the evaporation tank. Dilute the salt slurry to keep the liquid level in the evaporation tank.

[0046] The gauge pressure of the evaporator is generally controlled at 2,94*100000 Pascals, 1.013*10000 Pascals, the brine evaporates to supersaturation and precipitates mult...

Abstract

The invention provides a method for preparing refined natural nutrient salt, which comprises the following steps: preheating and evaporating; separating and backflowing; secondary crystallizing, drying and sieving. According to the invention, seawater is taken as a raw material which is cheap, no raw material competitions with other manufacturers is generated. The secondary crystallization theoryis used so that the crystallization speed is fast and the output is raised. The process of the invention keeps macronutrients in natural seawater and contains trace elements like calcium, magnesium, potassium, iron, copper and zinc which are good to human body, the output multi-element crystals make a contribution for raising the health level of human body, and have high social benefit. During the production process, a lot of magnesium ions are contained in brine all along, salt scale on a heating pipe is loosening and easy to treat without production stop for removing a scale layer of the heating pipe. The product of the invention is a good flavouring, and a nutriment and fresh-keeping product with cheap price.

Description

technical field [0001] The invention relates to a method for preparing food or food material, in particular to a method for preparing refined natural nutrient salt as seasoning. Background technique [0002] At present, domestic edible refined salt is made of sea salt or rock salt as raw material, and is made by the following processing method: first dissolve sea salt or rock salt with water to make brine, hereinafter referred to as brine, and then remove sand, sand, etc. through a sand filter. Then go through the preheater to the evaporator, pass superheated steam into the evaporator, heat the saturated brine, crystallize sodium chloride, and make the large-grained salt only contain a small amount of calcium, magnesium, potassium, etc. to remove impurities. Then drain the brine through a centrifuge, and dry to obtain the refined salt product. In addition, the beach-dried large-grained salt is crushed and then sent to the scrubber, washed with water or treated with chemical...
