Grainer Process
The Grainer evaporation process is a method of producing salt. This method uses shallow open pans with steam-heated immersion coils to evaporate the brine into salt. Sometimes it is paired with a partial-vacuum, to speed evaporation. See also * Alberger process The Alberger process is an industrial method of producing salt from rock salt. Method The Alberger process begins by heating brine under high pressure with a series of heaters. Impurities are removed using a tank filled with granite cubes called a ... {{industry-stub Industrial processes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. The open ocean has about of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food, including otherwise unpalatable food. Salting, brining, and pickling are also ancient and important methods of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, Greeks, Romans, Byzantines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

Brine
Brine is a high-concentration solution of salt (NaCl) in water (H2O). In diverse contexts, ''brine'' may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature). Brine forms naturally due to evaporation of ground saline water but it is also generated in the mining of sodium chloride. Brine is used for food processing and cooking (pickling and brining), for de-icing of roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalination, so it requires wastewater treatment for proper disposal or further utilization (fresh water recovery). In nature Brines are produced in multiple ways in nature. Modification of seawater via evaporation results in the concentration of salts in the residual fluid, a characteristic geologic deposit call ...

Alberger Process
The Alberger process is an industrial method of producing salt from rock salt. Method The Alberger process begins by heating brine under high pressure with a series of heaters. Impurities are removed using a tank filled with granite cubes called a graveler. When the pressure is released, salt crystals form in a steam heated evaporation pan. This results in a three-dimensional pyramid-shaped flake salt, which has low bulk density, high solubility, and good adhesion. According to a scientific article from 1946, the process results in salt of high purity but "is the least economical method for the production of a given quantity of salt." Production Cargill operates a plant in St. Clair, Michigan that is the only place in the United States that manufactures such salt using the Alberger process. Diamond Crystal Kosher Salt is a brand of salt produced using the alberger process. History The method was patented by Charles L. Weil on June 8, 1915.European Patent Office The European ...
