Huller
A rice huller or rice husker is an agricultural machine used to automate the process of removing the chaff (the outer husks) of grains of rice. Throughout history, there have been numerous techniques to hull rice. Traditionally, it would be pounded using some form of mortar and pestle. An early simple machine to do this is a rice pounder. Later even more efficient machinery was developed to hull and polish rice. These machines are most widely developed and used throughout Asia where the most popular type is the Engelberg huller designed by German Brazilian engineer Evaristo Conrado Engelberg in Brazil and first patented in 1885. The Engelberg huller uses steel rollers to remove the husk. Other types of huller include the disk or ''cono'' huller which uses an abrasive rotating disk to first remove the husk before passing the grain to conical rollers which polish it to make white rice; this is done repeatedly since other sides of circular side of rice are not husked.

Engelberg Huller Company
The Engelberg Huller Company was established in 1888 in Syracuse, New York, by John R. Montague, to manufacture and distribute the ''Engelberg Huller'' machine which was invented by Brazilian mechanical engineer and inventor, Evaristo Conrado Engelberg Evaristo Conrado Engelberg (26 October 1853–1932) was a Brazilian mechanical engineer and inventor. He is the inventor of the Engelberg huller, a machine used to strip the husks from rice and coffee during harvest. He was born to German i ..., and Willard Halstead to remove the husks and shells from rice and coffee during the milling process. The Engelberg Huller Company was sold to an agricultural equipment manufacturer located in Nicholson, Pennsylvania, in 1976. The CEO and owner in 1976 was James Solon.

Evaristo Conrado Engelberg
Evaristo Conrado Engelberg (26 October 1853–1932) was a Brazilian mechanical engineer and inventor. He is the inventor of the Engelberg huller, a machine used to strip the husks from rice and coffee during harvest. He was born to German immigrants in Piracicaba, São Paulo São Paulo (, ; Portuguese for 'Saint Paul') is the most populous city in Brazil, and is the capital of the state of São Paulo, the most populous and wealthiest Brazilian state, located in the country's Southeast Region. Listed by the Ga .... In 1885, while constructing a water wheel, Engelberg observed a group of slaves stripping rice pestles by hand, the main method at the time. He discovered that rubbing the rice between his fingers while applying pressure removed the pestle. He returned to his workshop and immediately began working on a machine that he finished the next day, thus creating the first rice peeler horizontal cylinder. The invention was named the Engelberg Huller and was soon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rice
Rice is the seed of the grass species '' Oryza sativa'' (Asian rice) or less commonly '' Oryza glaberrima'' (African rice). The name wild rice is usually used for species of the genera '' Zizania'' and ''Porteresia'', both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of '' Oryza''. As a cereal grain, domesticated rice is the most widely consumed staple food for over half of the world's human population,Abstract, "Rice feeds more than half the world's population." especially in Asia and Africa. It is the agricultural commodity with the third-highest worldwide production, after sugarcane and maize. Since sizable portions of sugarcane and maize crops are used for purposes other than human consumption, rice is the most important food crop with regard to human nutrition and caloric intake, providing more than one-fifth of the calories consumed worldwide by humans. There are many varieties of rice and culinary preferences t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Rice
White rice is milled rice that has had its husk, bran, and germ removed. This alters the flavor, texture and appearance of the rice and helps prevent spoilage, extend its storage life, and makes it easier to digest. After milling ( hulling), the rice is polished, resulting in a seed with a bright, white, shiny appearance. The milling and polishing processes both remove nutrients. An unbalanced diet based on unenriched white rice leaves many people vulnerable to the neurological disease beriberi, due to a deficiency of thiamine (vitamin B1). White rice is often enriched with some of the nutrients stripped from it during its processing. Enrichment of white rice with B1, B3, and iron is required by law in the United States when distributed by government programs to schools, nonprofits, or foreign countries. As with all natural foods, the precise nutritional composition of rice varies slightly depending on the variety, soil conditions, environmental conditions and types of ferti ...

Threshing Machine
A threshing machine or a thresher is a piece of farm equipment that threshes grain, that is, it removes the seeds from the stalks and husks. It does so by beating the plant to make the seeds fall out. Before such machines were developed, threshing was done by hand with flails: such hand threshing was very laborious and time-consuming, taking about one-quarter of agricultural labour by the 18th century. Mechanization of this process removed a substantial amount of drudgery from farm labour. The first threshing machine was invented circa 1786 by the Scottish engineer Andrew Meikle, and the subsequent adoption of such machines was one of the earlier examples of the mechanization of agriculture. During the 19th century, threshers and mechanical reapers and reaper-binders gradually became widespread and made grain production much less laborious. Michael Stirling is said to have invented a rotary threshing machine in 1758 which for forty years was used to process all the corn on ...

Rice Pounder
A rice pounder is an agricultural tool, a simple machine that is commonly used in Southeast Asia to dehull rice or to turn rice into rice flour. The device has similar functionality to a mortar and pestle, but with more mechanical advantage to conserve labor. Rice is dehulled by continually raising and then dropping the heavy head or pestle of the pounder into a block or mortar. Some rice pounders are foot-operated; the head is raised by standing on the handle of the device past its fulcrum (similar to a see-saw). Once raised, the user quickly steps off of the handle, allowing the heavy head to fall into the mortar and pulverize its contents. In Bengal (West Bengal, India and Bangladesh), this is called Dhenki, and is still used traditionally in the villages for personal use. This is because it preserves the brown rice coating that is perceived as a healthy part. However, because it is so labor-intensive, its use is gradually decreasing. Recently, complex mechanical dehusker ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rice Hulls
Rice hulls (or rice husks) are the hard protecting coverings of grains of rice. In addition to protecting rice during the growing season, rice hulls can be put to use as building material, fertilizer, insulation material, or fuel. Rice hulls are part of the chaff of the rice. Production Rice hulls are part of the rice seed. The hull protects the grain during the growing season from pests. The hull is formed from hard materials, including opaline silica and lignin. The hull is hard to eat or swallow (unless finely ground) and mostly indigestible to humans because of its enriched fibre components. However, during times of food scarcity in ancient China, a common daily meal was a pastry made from rice husks, wild vegetables, and soybean powder. This led to the idiom "meals of cereal, hulls, and vegetables for half a year," indicating poverty and food insecurity. Testing and commercialization of human grade anti-caking agents were done in the early 2000s. The material is appro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rice Polisher
A rice polisher is a machine for buffing (or "polishing") kernels of rice to change their appearance, taste, and texture or for transforming brown rice into white rice. Rice polishers are used after the rice has gone through the whitening process. They are abrasive machines that use talc or some other very fine dust to buff the outer surface of rice kernels. In Japanese farming communities, there is often a shared rice polishing machine. The first fully automated rice polishing machine is believed to have been patented by the English engineer and inventor Sampson Moore in 1861. In the 20th century, kitchen appliances for consumers were created that allowed individual cooks to polish rice in their homes. Components The polisher contains cones covered with leather strips and perforated screens. The leather strips on the cones rub the grain of rice over the screen repeatedly. The remaining particles on the rice are removed during this process, giving the grain of rice a shinier appe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winnowing Barn
Winnowing barns (or winnowing houses) were structures commonly found in South Carolina on antebellum rice plantations. A winnowing barn consists of a large shed on tall posts with a hole in the floor. Raw, husked rice was carried up into the barn by slaves and then the grain was dropped through the hole. As the grain dropped to the ground, the lighter and undesirable chaff was carried away in the wind, leaving a mound of purified rice grains directly below the winnowing barn. The purified grain was then packed into barrels and carried down river to port cities for distribution. Prior to the development of the winnowing barn, winnowing was done by hand using winnowing baskets — a long and labor-intensive process. Thus, the development of the winnowing barn helped South Carolina become the second largest exporter of rice in the world, next to Indonesia and the Far East.

Husk
Husk (or hull) in botany is the outer shell or coating of a seed. In the United States, the term husk often refers to the leafy outer covering of an ear of maize (corn) as it grows on the plant. Literally, a husk or hull includes the protective outer covering of a seed, fruit, or vegetable. It can also refer to the exuvia of insects or other small animals left behind after moulting. In cooking, hull can also refer to other waste parts of fruits and vegetables, notably the cap or sepal of a strawberry. The husk of a legume and some similar fruits is called a pod. Husking and dehulling Husking of corn is the process of removing its outer layers, leaving only the cob or seed rack of the corn. Dehulling is the process of removing the hulls (or chaff) from beans and other seeds. This is sometimes done using a machine known as a huller. To prepare the seeds to have oils extracted from them, they are cleaned to remove any foreign objects. Next, the seeds have their hulls, o ...

Chaff
Chaff (; ) is the dry, scaly protective casing of the seeds of cereal grains or similar fine, dry, scaly plant material (such as scaly parts of flowers or finely chopped straw). Chaff is indigestible by humans, but livestock can eat it. In agriculture it is used as livestock fodder, or is a waste material ploughed into the soil or burned. Etymology "Chaff" comes from Middle English ''chaf'', from Old English , related to Old High German ''cheva'', "husk". Grain chaff In grasses (including cereals such as rice, barley, oats, and wheat), the ripe seed is surrounded by thin, dry, scaly bracts (called glumes, lemmas and paleas), forming a dry husk (or hull) around the grain. Once it is removed it is often referred to as chaff. In wild cereals and in the primitive domesticated einkorn,Potts, D. T.
