Millstone
Millstones or mill stones are stones used in gristmills, used for triturating, crushing or, more specifically, grinding wheat or other grains. They are sometimes referred to as grindstones or grinding stones. Millstones come in pairs: a stationary base with a convex rim known as the bedstone (or nether millstone) and a concave-rimmed runner stone that rotates. The movement of the runner on top of the bedstone creates a "scissoring" action that grinds grain trapped between the stones. Millstones are constructed so that their shape and configuration help to channel ground flour to the outer edges of the mechanism for collection. The runner stone is supported by a cross-shaped metal piece ( millrind or rynd) fixed to a "mace head" topping the main shaft or spindle leading to the driving mechanism of the mill (wind, water (including tide), or other means). History The origins of an industry Often referred to as the "oldest industry", the use of the millstone is inextr ...

Gristmill
A gristmill (also: grist mill, corn mill, flour mill, feed mill or feedmill) grinds cereal grain into flour and Wheat middlings, middlings. The term can refer to either the grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for mill (grinding), grinding. History Early history The Greek geographer Strabo reported in his ''Geography'' that a water-powered grain-mill existed near the palace of king Mithradates VI Eupator at Cabira, Asia Minor, before 71 BC. The early mills had horizontal paddle wheels, an arrangement which later became known as the "Norse wheel", as many were found in Scandinavia. The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind against a stationary "Mill machinery#Watermill machinery, bed", a ...

Watermill
A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, and wire drawing mills. One major way to classify watermills is by wheel orientation (vertical or horizontal), one powered by a vertical waterwheel through a gear mechanism, and the other equipped with a horizontal waterwheel without such a mechanism. The former type can be further subdivided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and pitchback (backshot or reverse shot) waterwheel mills. Another way to classify water mills is by an essential trait about their location: tid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Millrind
A millrind or simply rind is an iron support, usually four-armed or cross-shaped, for the upper ("runner") stone in a pair of millstones. The rind is affixed to the top of the square-section main shaft or spindle and supports the entire weight of the runner stone, which can be as much as several tons. The face of a runner stone usually has a carved depression, called the "Spanish cross", to accommodate the millrind. The rind is necessary because the grain is fed through the runner stone's central hole, so the spindle cannot be inserted through it like a cartwheel on an axle. Mechanism A later refinement, replacing the cross, was to mount a ''mace'' onto the spindle, which fitted into a gimbal let into the runner stone. The device allowed the runner stone to move in two planes and thus follow the nether (stationary) stone more closely, but great care had to be taken to ensure that its weight was properly balanced. The separation of the nether stone from the runner, controlling th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Roller Milled White Enriched Flour
The Roller Mill was created by Hungarian bakers in the late 1860s and its popularity spread worldwide throughout the 1900s. Roller mills now produce almost all non-whole grain flour. Enriched flour is flour that meets an FDA standard in the United States. Roller milled white enriched flour makes up over 90% of the flour that comes out of the United States. The significance of the roller mill that produces white flour In 2017, well over 90% of the United States commercial flour production was not whole grain. Virtually all of this non-whole grain flour was produced on flour roller mills. These unique mills were first developed in Europe in the 1860s, soon after were patented and introduced into the United States and quickly came to dominate the world's flour milling industry as they continue to do today. Flour roller mills were specifically designed to efficiently separate the bran and germ elements of the wheat kernel. What remains is the endosperm, generally referred to as w ...

Tide Mill
A tide mill is a water mill driven by tidal rise and fall. A dam with a sluice is created across a suitable tidal inlet, or a section of river estuary is made into a reservoir. As the tide comes in, it enters the mill pond through a one-way gate, and this gate closes automatically when the tide begins to fall. When the tide is low enough, the stored water can be released to turn a water wheel. Tide mills are usually situated in river estuaries, away from the effects of waves but close enough to the sea to have a reasonable tidal range. Cultures that built such mills have existed since the Middle Ages, and some may date back to the Roman period. A modern version of a tide mill is the electricity-generating tidal barrage. Early history Possibly the earliest tide mill in the Roman world was located in London on the River Fleet, dating to Roman times. Since the late 20th century, a number of new archaeological finds have consecutively pushed back the date of the earliest t ...

Windmill
A windmill is a machine operated by the force of wind acting on vanes or sails to mill grain (gristmills), pump water, generate electricity, or drive other machinery. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines have been known earlier, the Babylonian emperor Hammurabi had used wind mill power for his irrigation project in Mesopotamia in the 17th century BC. Later, Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der östlichen zur westlichen Windmühle", ''Archiv für Kulturgeschichte'', Vol. 77, Issue 1 (1995), pp. 1–30 (10f.)

Bush Medicine
Bush medicine comprises traditional medicines used by Indigenous Australians, being Aboriginal and Torres Strait Islander people. Indigenous people have been using various components of native Australian flora and some fauna as medicine for thousands of years, and a minority turn to healers in their communities for medications aimed at providing physical and spiritual healing. Traditional methods of healing have underwritten the development of non-Indigenous medicines throughout history. One notable example would be the development of a seasickness medication. Today, traditional healers and medicines have been incorporated into modern clinical settings to help treat sick Indigenous people within some healthcare networks. Overview Traditional medicine has been defined as the sum of the total knowledge, skills and practices based on the theories, beliefs and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health, as we ...

Pestle
A mortar and pestle is a set of two simple tools used to prepare ingredients or substances by compression (physics), crushing and shear force, grinding them into a fine Paste (rheology), paste or powder in the kitchen, laboratory, and pharmacy. The ''mortar'' () is characteristically a bowl, typically made of hardwood, metal, ceramic, or hard stone such as granite. The ''pestle'' (, also ) is a blunt, club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar where the pestle is pounded, pressed, or rotated into the substance until the desired texture is achieved. Mortars and pestles have been used in cooking since the Stone Age; today they are typically associated with the pharmacy profession due to their historical use in preparing medicines. They are used in chemistry settings for pulverizing small amounts of chemicals; in arts and cosmetics for pulverizing pigments, binders, and other substances; in ceramics for making Grog (clay), grog; ...

Aboriginal Victorians
Aboriginal Victorians, the Aboriginal Australians of Victoria, Australia, occupied the land for tens of thousands of years prior to European settlement. Aboriginal people have lived a semi-nomadic existence of fishing, hunting and gathering and associated activities for at least 40,000 years. The Aboriginal people of Victoria had developed a varied and complex set of languages, tribal alliances, beliefs and social customs that involved totemism, superstition, initiation and burial rites, and tribal moieties. History Prehistory There is some evidence to show that people were living in the Maribyrnong River valley, near present-day Keilor, about 40,000 years ago, according to Gary Presland. At the Keilor archaeological site a human hearth excavated in 1971 was radiocarbon-dated to about 31,000 years BP, making Keilor one of the earliest sites of human habitation in Australia.Gary Presland, Keilor Archaeological Site', eMelbourne website.

Aboriginal Australians
Aboriginal Australians are the various indigenous peoples of the Mainland Australia, Australian mainland and many of its islands, excluding the ethnically distinct people of the Torres Strait Islands. Humans first migrated to Australia (continent), Australia 50,000 to 65,000 years ago, and over time formed as many as 500 List of Aboriginal Australian group names, language-based groups. In the past, Aboriginal people lived over large sections of the continental shelf. They were isolated on many of the smaller offshore islands and Tasmania when the land was inundated at the start of the Holocene Interglacial, inter-glacial period, about 11,700 years ago. Despite this, Aboriginal people maintained extensive networks within the continent and certain groups maintained relationships with Torres Strait Islanders and the Makassar people, Makassar people of modern-day Indonesia. Over the millennia, Aboriginal people developed complex trade networks, inter-cultural relationships, law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
