Ginger root Botanical name: Zingiber officinale Linn. Family: Zingiberaceae. Ginger oil and oleoresins are the volatile oil derived by steam distillation of ginger and oleoresin. It is obtained by percolating the powdered rhizomes of Ginger, Zingiber officinale with volatile solvents. Ginger contains 1-2 percent of volatile oil, 5-8 percent of pungent acrid oleoresin and starch. Zingiberene is the chief constituent in the oil of ginger. Oil is employed for flavoring all kinds of food products and confectionary and finds limited use in perfumery. Oleoresin, commercially called Gingerin contains pungent principles viz. gingerol and shogaol apart from the volatile oil of ginger and is used as an aromatic, carminative, stomachic and as a stimulant. Oleoresin from ginger is obtained conventionally by extraction of dried powdered ginger with organic solvents like ethyl acetate, ethanol or acetone. Commercial dried ginger yields 3.5-10.0 per cent oleoresin. Ginger oleoresin is a dark brown viscous liquid responsible for the flavour and pungency of the spice. Ginger of commerce or `Adrak` is the dried underground stem or rhizome of the plant, which constitutes one of the five most important major spices of India, standing third or fourth, competing with chillies, depending upon fluctuations in world market prices, world market demand and supply position. Ginger, like cinnamon, clove and pepper, is one of the most important and oldest spices. It consists of the prepared and sun dried rhizomes known in trade as `hands` and `races` which are either with the outer brownish cortical layers (coated or unscraped), or with outer peel or coating partially or completely removed. Ginger requires a warm and humid climate. It is cultivated from sea level to an altitude of 1500 meters, either under heavy rainfall conditions of 150 to 300 cm or under irrigation. The crop can thrive well in sandy or clayey loam or lateritic soils. The composition of dry ginger is given below: Dry Ginger rootMoisture:6.9 % Protein:8.6 % Fat:6.4 % Fiber:5.9 % Carbohydrates:66.5 % Ash:5.7 % Calcium:0.1 % Phosphorous:.15 % Iron:0.011 % Sodium:0.03 % Potassium:1.4 % Vitamin A:175 I.U./100 g Vitamin B1:0.05 mg/100 g Vitamin B2:0.13 mg/100 g Niacin:1.9 mg/100 g Vitamin C:12.0 mg/100 g Calorific value:380 calories/100 g. Ginger Oleoresin is obtained by extraction of powdered dried ginger with suitable solvents like alcohol, acetone etc. Unlike volatile oil, it contains both the volatile oil and the non-volatile pungent principles for which ginger is so highly esteemed. Concentration of the acetone extract under vacuum and on complete removal of even traces of the solvent used, yields the so called oleoresin of ginger. Ginger oleoresin is manufactured on a commercial scale in India and abroad and is in great demand by the various food industries.

As well as can provide thermal insulation aluminum coil, color aluminum coil, with pattern aluminum coil, without viscosity, double-sided conductive high-quality aluminum. It can also be processed into different profiles. As a new type of metal material, aluminum alloy plate has been widely used in various fields in recent years. Its characteristics are in the following aspects: 1. Light weight and high strength. 2. Good corrosion resistance. 3. Good thermal conductivity. 4. Beautiful and practical. Aluminum foil and aluminum coil, as the two main forms of aluminum materials, are widely used in many industries. Although they are of the same origin, they differ in their characteristics and uses. Aluminum foil, known for its thin and flexible, thickness is usually less than 0.2mm, is the ideal choice for food packaging, electronics industry. The aluminum coil, with a thickness greater than 0.2mm, is known for its robustness and durability, and is often used in the construction field of roofs, wallboards and so on. In the field of application, aluminum foil shines in food packaging with its good sealing and toughness, such as the anti-paste and anti-drying when barbecuing and roasting chicken. The aluminum coil, because of its strength and hardness, has become an indispensable material in the construction field. Although both have the advantages of lightweight, easy processing and corrosion resistance, they also have disadvantages. Aluminum foil is thin and easy to tear, and aluminum rolls are difficult to bend and deform.

AINiCo is composed primarily of Aluminum Nickel Cobalt and also Copper and Titanium. They are manufactured through either casting or sintering process. Cast AINiCo may be manufactured in complex shapes such as horseshoes not possible with other magnet materials. Sintered AINiCo offer slightly lower magnetic properties but better mechanical characteristics. it can be efficiently magnetized in any direction, and for anisotropic AINiComagnet, it generally has greater magnetic capacitive in a preferred orientation than isotropic types. AINiCo is hard and brittle, Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances. â?¢ Advantages of AlNiCo Magnet: 1.Customized designs are available. 2.Max working temperature can be as high as 550�°C. 3.Disadvantage: Br and BH(max)are not as high as rare earth magnet. 4.High energies and relatively low coercivity. 5.High magnetic flux density; low mold charge stable temperature properties; easy to shap.
Neodymium magnets (also known as NdFeB, Neo or NIB magnets), are strong permanent magnets made from an alloy of neodymium, iron & boron. Part of the Rare-Earth magnet family, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low-cost, they are the preferred choice for many consumers, commercial, industrial and technical applications.NdFeB is divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB is magnetic in all directions and corrosion resistance and is divided into Bonded Compression NdFeB Magnet and Bonded Injection NdFeB Magnet; while sintered NdFeB is easy to corrosion, the surface requires coating, generally divided into axial and radial magnetic charging. Advantages of Sintered NdFeB Magnet : 1. Very hard and brittle, high diamagnetic resistance, high cost / performance ratio, not suitable for high working temper ature; 2. Magnetic performance is higher than that of the rare earth cobalt permanent magnet, the residual magnetic induction strength, magnetic induction coercivity, the maximum magnetic energy product is very high, is the current magnetic performance of the best permanent magnet; 3. High cost performance.
