Cane Sugar Mill
A sugar cane mill is a factory that processes sugar cane to produce raw sugar or plantation white sugar. Some sugar mills are situated next to a back-end refinery, that turns raw sugar into (refined) white sugar. The term is also used to refer to the equipment that crushes the sticks of sugar cane to extract the juice. Production of raw sugar There are a number of steps in producing raw sugar from cane: # Harvest and transport to the sugar factory # Juice extraction (cane preparation followed by milling or diffusion) # Purification of the juice (remove suspended solids from the juice, typically mud, waxes, fibres) # Evaporation of water (to concentrate the juice to a thick syrup of about 65°brix) # Crystallization # Centrifugation (Separation of the sugar crystals from the mother liquor, done by centrifugal machines) # Storage of sugar and molasses These processing steps will produce a brown or raw sugar. Raw sugar is generally sent to a sugar refinery to produce white sug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inkerman Mill
Inkerman (; ; ) is a List of cities in Crimea, city in the Crimea, Crimean peninsula. It is ''de facto'' within the Federal cities of Russia, federal city of Sevastopol within the Russia, Russian Federation, but ''de jure'' within the Autonomous Republic of Crimea within Ukraine. It lies 5 kilometres (3 miles) east of Sevastopol, at the mouth of the Chernaya River (Ukraine), Chernaya River which flows into Sevastopol Bay, Sevastopol Inlet (also called the North Inlet). Administratively, Inkerman was subordinate to the municipality of Sevastopol, but since September 2023 it ''de jure'' became a part of Bakhchysarai Raion of AR Crimea. Population: The name ''Inkerman'' is said to mean 'cave fortress' in Turkish. During the Soviet Union, Soviet era, the area was known between 1976 and 1991 as ''Bilokamiansk'' () or ''Belokamensk'' (), which literally means 'white stone city', in reference to the soft white stone quarried in the area and commonly used for construction. In 1991 the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaching (chemistry)
Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent. Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size. Leaching can occur naturally seen from plant substances (inorganic and organic), solute leaching in soil, and in the decomposition of organic materials. Leaching can also be applied affectedly to enhance water quality and contaminant removal, as well as for disposal of hazardous waste products such as fly ash, or rare earth elements (REEs). Understanding leaching characteristics is important in preventing or encouraging the leaching process and preparing for it in the case where it is inevitable. In an ideal leaching equilibrium stage, all the solute is dissolved by the solvent, lea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifuge
A centrifuge is a device that uses centrifugal force to subject a specimen to a specified constant force - for example, to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids. It works by causing denser substances and particles to move outward in the radial direction. At the same time, objects that are less dense are displaced and moved to the centre. In a laboratory centrifuge that uses sample tubes, the radial acceleration causes denser particles to settle to the bottom of the tube, while low-density substances rise to the top. A centrifuge can be a very effective filter that separates contaminants from the main body of fluid. Industrial scale centrifuges are commonly used in manufacturing and waste processing to sediment suspended solids, or to separate immiscible liquids. An example is the cream separator found in da ...

Viscosity
Viscosity is a measure of a fluid's rate-dependent drag (physics), resistance to a change in shape or to movement of its neighboring portions relative to one another. For liquids, it corresponds to the informal concept of ''thickness''; for example, syrup has a higher viscosity than water. Viscosity is defined scientifically as a force multiplied by a time divided by an area. Thus its SI units are newton-seconds per metre squared, or pascal-seconds. Viscosity quantifies the internal friction, frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's center line than near its walls. Experiments show that some stress (physics), stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion. For a tube ...

Supersaturation
In physical chemistry, supersaturation occurs with a solution (chemistry), solution when the concentration of a solute exceeds the concentration specified by the value of solubility at Solubility equilibrium, equilibrium. Most commonly the term is applied to a solution of a solid in a liquid, but it can also be applied to liquids and gases dissolved in a liquid. A supersaturated solution is in a metastable state; it may return to equilibrium by separation process, separation of the excess of solute from the solution, by dilution of the solution by adding solvent, or by increasing the solubility of the solute in the solvent. History Early studies of the phenomenon were conducted with sodium sulfate, also known as Glauber's Salt because, unusually, the solubility of this salt in water may decrease with increasing temperature. Early studies have been summarised by Tomlinson. It was shown that the crystallization of a supersaturated solution does not simply come from its agitation ...

Inverted Sugar Syrup
Inverted sugar syrup is a syrup mixture of the monosaccharides glucose and fructose, made by splitting disaccharide sucrose. This mixture's optical rotation is opposite to that of the original sugar, which is why it is called an ''invert'' sugar. Splitting is completed through hydrolytic saccharification. It is 1.3x sweetness, sweeter than table sugar, and foods that contain invert sugar retain moisture better and crystallize less easily than those that use table sugar instead. Bakers, who call it invert syrup, may use it more than other sweeteners. Other names include invert sugar, simple syrup, sugar syrup, sugar water, bar syrup, and sucrose inversion. Production Additives Commercially prepared enzyme-catalyzed solutions are inverted at . The optimum pH for inversion is 5.0. Invertase is added at a rate of about 0.15% of the syrup's weight, and inversion time will be about 8 hours. When completed the syrup temperature is raised to inactivate the invertase, but the syrup i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiple-effect Evaporator
In chemical engineering, a multiple-effect evaporator is an apparatus for efficiently using the heat from steam to evaporate water. Water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapor boiled off in one vessel can be used to heat the next, and only the first vessel (at the highest pressure) requires an external source of heat. The multiple-effect evaporator was invented by the American ( Louisiana Creole) engineer Norbert Rillieux. Although he may have designed the apparatus during the 1820s and constructed a prototype in 1834, he did not build the first industrially practical evaporator until 1845. Originally designed for concentrating sugar in sugar cane juice, it has since become widely used in all industrial applications where large volumes of water must be evaporated, such as salt production and water desalination. Multiple-effect evaporation comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supernatant
In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". The solid formed is called the precipitate. In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant. The clear liquid remaining above the precipitated or the centrifuged solid phase is also called the supernate or supernatant. The notion of precipitation can also be extended to other domains of chemistry (organic chemistry and biochemistry) and even be applied to the solid phases (e.g. metallurgy and alloys) when solid impurities segregate from a solid phase. Supersaturation The precipitation of a compound may occur when its concentration exceeds its solubility. This can be due to temperature changes, solvent evaporation, or by mixing solvents. Precipitation occurs more rapidly from a strongly supersaturated solution. The formation of a precipitate can be caused by a che ...

Flash Evaporation
Flash evaporation (or partial evaporation) is the partial vapor that occurs when a saturated liquid stream undergoes a reduction in pressure by passing through a throttling valve or other throttling device. This process is one of the simplest unit operations. If the throttling valve or device is located at the entry into a pressure vessel so that the flash evaporation occurs within the vessel, then the vessel is often referred to as a flash drum. If the saturated liquid is a single-component liquid (for example, propane or liquid ammonia), a part of the liquid immediately "flashes" into vapor. Both the vapor and the residual liquid are cooled to the saturation temperature of the liquid at the reduced pressure. This is often referred to as "auto-refrigeration" and is the basis of most conventional vapor compression refrigeration systems. If the saturated liquid is a multi-component liquid (for example, a mixture of propane, isobutane and normal butane), the flashed vapor i ...
