| 41 | FREE FLOWING 100-500 MICROMETER SIZE SPHERICAL CRYSTALS OF COMMON SALT AND PROCESS FOR PREPARATION THEREOF | US13689468 | 2012-11-29 | US20130087642A1 | 2013-04-11 | INDRAJIT MUKHOPADHYAY; PUSHPITO KUMAR GHOSH; VADAKKE PUTHOOR MOHANDAS |
| The present invention provides spherical shaped crystals of common salt having size distribution in the range of 100-500 μm and a process for preparation of the said salt. The above mentioned size range is relevant for many important edible and non-edible applications of salt. The salt is demonstrated to have superior flow properties compared to the cubic counterpart. The free flow property of the salt can be further enhanced through surface treatment with additive such as glycine. The salt is produced by cost-effective mechanical means and such production is amenable to scale up. | ||||||
| 42 | Compacted granular potassium chloride, and method and apparatus for production of same | US10838178 | 2004-05-03 | US20050036929A1 | 2005-02-17 | Del Ferguson; Rob Plosz; Annette Revet; Doug LaRocque; Peter Jackson; Carey Heinbigner; Dave Zirk; Scott St. Germaine |
| Apparatus and method are disclosed for the production of compacted granular potassium chloride with improved handling qualities. A binding ingredient such as sodium hexametaphosphate is blended with the potassium chloride feed material in advance of compaction. The product of this apparatus and method has improved handling, storage, strength and other qualities over compacted granular potassium produced using prior art methods. | ||||||

| The invention provides a common salt having the rounded-off savory taste of natural common salt and yet a reduced tendency toward deliquescence and coagulation and a process for producing the same. The invention further provides a method for fractional recovery of freshwater and raw materials for the above common salt from seawater in connection with the production of the same common salt. The common salt of the invention is a bittern-containing granular common salt with each of its grains consisting of a core comprised of a bittern-containing composition optionally containing NaCl and, as covering the grain, a coating layer comprised of a NaCl-containing composition optionally containing CaSO4 or bittern. The method for fractional recovery of freshwater and raw materials for the above common salt from seawater according to the invention comprises a step of treating seawater with a reverse osmosis membrane to fractionate it into freshwater and a salt-containing water and subjecting the salt-containing water to an ion exchange treatment to fractionate it into a NaCl-containing composition and a bittern-containing composition or a step of subjecting seawater to an ion exchange treatment to fractionate it into an aqueous NaCl-containing solution and an aqueous bittern-containing solution and subjecting each of the aqueous NaCl-containing solution and aqueous bittern-containing solution to a reverse osmosis membrane treatment to fractionate it into freshwater and either a NaCl-containing composition or a bittern-containing composition. | ||||||

| Method for producing salt grains in which the salt is dissolved in a liquid solvent inside a mixing tank so as to form a saline solution which is supersaturated with salt and which is then atomized inside a drying tower where a stream of hot air circulates; the atomizing process being designed to produce a plurality of drops of saline solution, all of approximately the same size, and the stream of hot air being designed to evaporate the liquid solvent contained in each drop so as to cause the salt present in the said drop to solidify into a salt grain of essentially spherical shape; given that the dimensions of the salt grains depend on the dimensions of the drops of saline solution, it is possible to obtain salt grains of the desired size by producing drops of saline solution of a suitable size during the atomizing process. | ||||||

| A water soluble dicarboxylic acid or an alkali metal salt thereof acts as a mold release agent for salt pellets when a salt-contacting surface of a roll-type briquetting press is coated with from about 0.02 to about 5 mg/cm.sup.2 of a powder of the acid or alkali metal salt just prior to a charge of salt. The coating is achieved by spraying an air stream entraining the powder onto the press rolls or by spraying a solution of the release agent onto the rolls and evaporating the solvent to leave the powder on the rolls. The acid has from 6 to 10 carbon atoms; adipic acid being preferred. Salt pellets having a layer of the powder on their surface may be used in water softening systems wherein the pellets sit in a brine reservoir and supply salt for the recharging of an ion exchange resin. There is no formation of an unsightly scum on the surface of the brine and on the sides of the reservoir. | ||||||

| A water soluble dicarboxylic acid acts as a mold release agent for salt blocks when it is sprayed as a fine powder into the block press mold box just prior to a charge of salt. The acid has from 6 to 10 carbon atoms; adipic acid is a preferred release agent. The salt block having a layer of the acid on it surface may be used in water softening systems wherein the block sits in a brine reservoir and supplies salt for the recharging of an ion exchange resin. There is no build up of an unsightly scum on the surface of the brine and on the sides of the reservoir as there has been with the use of calcium stearate as the release agent. | ||||||

| Process for the production of salt in which sodium chloride is crystallized in the form of spheres by evaporation of a sodium chloride brine and the spheres obtained are then broken up. The salt produced by the process is particularly suitable for the food industry. | ||||||

| Recrystallization of sodium chloride in the form of high-purity cubic crystals from a sodium chloride source containing calcium sulphate impurity by multieffect evaporation preceded by treatment of the hot sodium chloride saturated brine by flocculents and settling, to cause the undissolved calcium sulphate particles and any other suspended solids to agglomerate and settle out of the brine prior to recrystallization of the sodium chloride. The conventional requirement for filtering the hot brine is completely eliminated.
