Beet Sugar Factory
A beet sugar factory or sugar factory, is a type of sugar production facility that produces sugar from sugar beets. Nowadays most sugar factories also act as a sugar refinery. The first beet sugar factory was made in the 1802. Sugar mill, factory and refinery Beet sugar factories can differ in the extent of the processing: *Most process sugar beet to white sugar (sucrose or "table sugar"). *Some process beet only as far as an intermediate stage (an unrefined 'raw' sugar or concentrated sugar solution) to be refined elsewhere. *A few process beet and also process raw sugar from cane in their refining section. The terms sugar mill and sugar refinery were older than the term sugar factory. In the 18th century, the only practical way to produce (raw) sugar was to extract it from the sugar cane. The extraction was done with a machine called the sugar mill, which pressed the juice out the sugar cane. Later, the term sugar mill was also applied to the whole facility that produced ...

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, leaving th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precipitation (chemistry)
In an aqueous solution, precipitation is the process of transforming a dissolved substance into an insoluble solid from a super-saturated 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 formatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milk Of Lime
Limewater is the common name for a saturated aqueous solution of calcium hydroxide. Calcium hydroxide, Ca(OH)2, is sparsely soluble at room temperature in water (1.5 g/L at 25 °C). "Pure" (i.e. less than or fully saturated) limewater is clear and colorless, with a slight earthy smell and an astringent/bitter taste. It is basic in nature with a pH of 12.4. Limewater may be prepared by mixing calcium hydroxide (Ca(OH)2) with water and removing excess undissolved solute (e.g. by filtration). When excess calcium hydroxide is added (or when environmental conditions are altered, e.g. when its temperature is raised sufficiently), a milky solution results due to the homogeneous suspension of excess calcium hydroxide. This liquid has been known traditionally as milk of lime. Chemistry An experiment commonly used to demonstrate the interaction of CO2 and Ca(OH)2 is as follows. Resultant carbon dioxide passed through limewater in the right tube, producing a milky solution due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbonatation
Carbonatation is a chemical reaction in which calcium hydroxide reacts with carbon dioxide and forms insoluble calcium carbonate: :Ca(OH)2CO2->CaCO3H_2O The process of forming a carbonate is sometimes referred to as "carbonation", although this term usually refers to the process of dissolving carbon dioxide in water. Concrete Carbonatation is a slow process that occurs in concrete where lime ( CaO, or Ca(OH)2( aq)) in the cement reacts with carbon dioxide (CO2) from the air and forms calcium carbonate. The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 12.5 to 13.5. This highly alkaline environment is one in which the steel rebar is passivated and is protected from corrosion. According to the Pourbaix diagram for iron, the metal is passive when the pH is above 9.5.{{cite web , url=http://www.corrosion-doctors.org/Thermo/ironE-pH.htm , title=Pourbaix diagram of iron , publisher=Corrosion-doctors.org , date= , accessdate=2 ...

Sugar Beet Cossettes
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. Simple sugars, also called monosaccharides, include glucose, fructose, and galactose. Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar is a refined form of sucrose. In the body, compound sugars are hydrolysed into simple sugars. Longer chains of monosaccharides (>2) are not regarded as sugars, and are called oligosaccharides or polysaccharides. Starch is a glucose polymer found in plants, the most abundant source of energy in human food. Some other chemical substances, such as glycerol and sugar alcohols, may have a sweet taste, but are not classified as sugar. Sugars are found in the tissues of most plants. Honey and fruits are abundant natural sources of simple sugars. Sucrose is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formaldehyde
Formaldehyde ( , ) ( systematic name methanal) is a naturally occurring organic compound with the formula and structure . The pure compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous solution (formalin), which is also used to store animal specimens. It is the simplest of the aldehydes (). The common name of this substance comes from its similarity and relation to formic acid. Formaldehyde is an important precursor to many other materials and chemical compounds. In 1996, the installed capacity for the production of formaldehyde was estimated at 8.7 million tons per year. It is mainly used in the production of industrial resins, e.g., for particle board and coatings. Forms Formaldehyde is more complicated than many simple carbon compounds in that it adopts several diverse forms. These compounds can often be used interchangeably and can be interconverted. *Molecular for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invert Sugar
Inverted sugar syrup, also called invert syrup, invert sugar, simple syrup, sugar syrup, sugar water, bar syrup, syrup USP, or sucrose inversion, is a syrup mixture of the monosaccharides glucose and fructose, that is made by hydrolytic saccharification of the disaccharide sucrose. This mixture's optical rotation is opposite to that of the original sugar, which is why it is called an ''invert'' sugar. It is sweeter than table sugar, and foods that contain invert sugar retain moisture better and crystallize less easily than do those that use table sugar instead. Bakers, who call it ''invert syrup'', may use it more than other sweeteners. Production Plain water Inverted sugar syrup can be made without acids or enzymes by heating it up alone: two parts granulated sugar and one part water, simmered for five to seven minutes, will be partly inverted. The amount of water can be increased to increase the time it takes to reach the desired final temperature, and increasing the ...

Vinasse
Vinasse is a byproduct of the sugar or ethanol industry. Sugarcane or sugar beet is processed to produce crystalline sugar, pulp and molasses. The latter are further processed by fermentation to ethanol, ascorbic acid or other products. Juice sugarcane can also be processed directly by ethanol fermentation. After the removal of the desired product (alcohol, ascorbic acid, etc.) the remaining material is called vinasse. Vinasse is sold after a partial dehydration and usually has a viscosity comparable to molasses. Commercially offered vinasse comes either from sugar cane and is called cane-vinasse or from sugar beet and is called beet-vinasse. Vinasse produced from sugar cane is also called dunder. In the process of distillation of the alcohol and as a result of the heating in the distillation process, in the pulp of the beet reactions of condensation and predominantly molecular ruptures take place. This causes a high fulvic acid concentration in this byproduct. One use of vinasse i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screw Press
A screw press is a type of machine press in which the ram is driven up and down by a screw. The screw shaft can be driven by a handle or a wheel. It works by using a coarse screw to convert the rotation of the handle or drive-wheel into a small downward movement of greater force. The overhead handle usually incorporates balls as flyweights. The weights helps to maintain the momentum and thrust of the tool to make it easier to operate. The screw press was first invented and used by the Romans in the first century AD. It was used primarily in wine and olive oil production. The screw press was also used in Gutenberg's printing press in the mid-15th century. A press for metalworking is a machine tool used to shape or cut metal by deforming it with a die. It is frequently used to punch holes in sheet metal in one operation, rather than by cutting the hole or drilling. A screw press is often used in hand book binding to help keep the covers of books flat and parallel to the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beet Pulp
Beet pulp is a byproduct from the processing of sugar beet which is used as fodder for horses and other livestock. Beet pulp is the fibrous material left over after the sugar is extracted from sugar beets. It is supplied either as dried flakes or as compressed pellets, but when fed to horses it should always be soaked in water first. Composition Despite being a byproduct of sugar beet processing, beet pulp itself is low in sugar and other non-structural carbohydrates, but high in energy and fiber.Warren, Lori K.
