Salt production method

The main results are as follows: 1. There are ten methods to prepare salt: sun salt, boiling evaporation, filtering water to make salt, dripping crystallization method, frozen salt extraction method, electrolysis method, hot water dissolution method, icing method, distillation method and microbial method.

2. The production method of salt is to collect raw materials, evaporate concentration, crystallization, repeated purification and so on. The raw materials for collecting raw salt are generally collected from sea water, lake water or well water, among which seawater salt is the most common. After brine collection, impurities need to be removed by filtration first.

3. Salt is made by evaporation. Usually, salt is extracted from sea water or lake water. First of all, introduce sea water or lake water into shallow water areas such as salt fields, shallow ponds or salt ponds. With the exposure of the sun and the action of the natural wind, the water body gradually evaporates, leaving salt.

4. The production methods of salt include sun salt method, salt burning method, evaporation crystallization method, compression crystallization method and so on. In the sun-drying method, natural sea water or underground salt water is poured directly into a flat salt field, allowing the water to evaporate, leaving behind sun-dried salt. This is the most primitive method of making salt and one of the simplest methods.

How is salt made?

The main results are as follows: 1. The commonly used methods are moisture absorption, brine production, crystallization, salt collection and salt washing. The crude salt obtained after evaporation is dissolved, precipitated, filtered and evaporated to get refined salt, and finally other elements are added according to the actual situation. Take the tide. Moisture absorption is actually a raw material extraction process for the production of raw salt.

2. At present, the methods of salt include evaporation of sea water, mining, chemical synthesis of salt and so on. The method of evaporating sea water collects sea water into a large pond or tank, then evaporates it with solar or thermal energy, leaving salt at the bottom. This is one of the oldest and most common ways of producing salt.

3. The salting method uses the heat of the sun. By building salt paddies and putting in the right amount of sea water, the heat emitted by the sun is used to evaporate the water in the sea water, and the rest is sea salt. The salt boiling method uses artificial boiling of the sea water to make the water in the sea water evaporate and eventually leave salt.

4. At present, salt is made by sea water salting method and vacuum evaporation method. Seawater salting method refers to the evaporation of water in seawater to get sea salt through a series of processes. To use this method, it is necessary to select a large area of flat seaside shoals in areas with mild climate and sufficient light to build salt fields.

5. Lake salt is divided into primary salt and regenerated salt, mainly by mining method or beach drying method. As far as mining is concerned, some lakes can be directly fished without processing after long-term evaporation and salt precipitation at the bottom of the lake. For example, the salt lake in the Qaidam Basin has formed a dry lake after tens of millions of years of changes, and its salt is exposed on the surface.

6. Salt can be extracted by evaporation, boiling salt and freezing. Evaporation is the oldest way for human beings to obtain salt crystallization, which refers to the use of solar radiation to evaporate to table salt, which can be applied to sea salt, lake salt and pond salt. Also known as boiling method, is the use of firepower evaporation to concentrate brine to produce salt.

How to make salt?

Common salt production methods: sun salt method, salt burning method, evaporation crystallization method. In the sun-drying method, natural sea water or underground salt water is poured directly into a flat salt field, allowing the water to evaporate, leaving behind sun-dried salt. This is the most primitive method of making salt and one of the simplest methods.

The production methods of salt are collecting raw materials, evaporating concentration, crystallization, repeated purification and so on. The raw materials for collecting raw salt are generally collected from sea water, lake water or well water, among which seawater salt is the most common. After brine collection, impurities need to be removed by filtration first.

The methods of evaporating sea water, mining and chemical synthesis of salt are used to make salt. Evaporation of seawater: collecting sea water into a large pond or tank, then evaporating it with solar or thermal energy, eventually leaving salt at the bottom, which is one of the oldest and most common ways of producing salt.

Evaporation of seawater: this method involves storing sea water in a large pond or tank, using solar or thermal energy to remove water and leave salt. This is a salt production method with a long history.

The production methods of edible salt include accepting tide, drying mud, making bittern, drying salt, collecting salt and so on. Tide-bearing seawater is the main raw material for salt production. Whenever the sea is at high tide, the whole salt field will be flooded. When the sea water recedes and the soil is soaked in sea water, it is filled with salt. The ponds dug by salt workers in the salt fields will be filled with sea water.

The production methods of salt are: sun salt method, boiling salt method. The salting method uses the heat of the sun, through the construction of salt fields, put in the right amount of sea water, use the heat emitted by the sun to evaporate the water in the sea water, and the rest is sea salt.

Preparation method of edible salt

1. There are several methods to make edible salt: sun salt method, salt burning method, evaporation crystallization method, compression crystallization method and so on. In the sun-drying method, natural sea water or underground salt water is poured directly into a flat salt field, allowing the water to evaporate, leaving behind sun-dried salt. This is the most primitive method of making salt and one of the simplest methods.

2. The salt in the sea water is turned into edible salt through the following steps: evaporation: the sea water is introduced into the salt field, and the water is gradually evaporated by sunlight and wind, so that the salt crystals precipitate. Crude salt: the crystallization of evaporated sea water is crude salt, which contains a variety of impurities and water, which will produce bitter taste.

3. The production method of edible salt: accepting tide, making bittern, crystallization and collecting salt. Moisture absorption is actually a raw material extraction process for the production of raw salt. Seawater is the raw material for the production of salt industry. In order to ensure the normal production, we must do everything possible to ensure the supply of raw materials.
