Flensing
Flensing is the removing of the blubber or outer integument of whales, separating it from the animal's meat. Processing the blubber (the subcutaneous fat) into whale oil was the key step that transformed a whale carcass into a stable, transportable commodity. It was an important part of the history of whaling. The whaling that still continues in the 21st century is both industrial and aboriginal. In aboriginal whaling the blubber is rarely rendered into oil, although it may be eaten as ''muktuk''. Terminology English whalemen called it ''flenching'', while American whalemen called it ''cutting-in''. Open-boat Shore and bay whaling In Spitsbergen, in the first half of the 17th century, the processing of whales was primarily done ashore. Where the whale was flensed differed between the English and Dutch. The English brought the whale to the stern of the ship, where men in a boat cut strips of blubber from the whale's back. These were tied together and rowed ashore, where th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trypot
A try pot is a large pot used to remove and render the oil from blubber obtained from cetaceans (whales and dolphins) and pinnipeds (seals), and also to extract oil from penguins. Once a suitable animal such as a whale had been caught and killed, the blubber was stripped from the carcass in a process known as flensing, cut into pieces, and melted in the try pots to extract the oil. Early on in the history of whaling, vessels had no means to process blubber at sea and had to bring it into port for processing. Later, though, whaling vessels frequently included a trywork, a brick furnace and set of try pots built into the deck. In the 18th- and 19th-century New England whaling industry, the use of the trywork allowed ships to stay at sea longer and boil out their oil. The slices of blubber were kept as thin as possible for the process, and on New England whaling ships, these slices were called "bible leaves" by the sailors. The use of an onboard trywork was the major technological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sperm Whale
The sperm whale or cachalot (''Physeter macrocephalus'') is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus ''Physeter'' and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus ''Kogia''. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. Females and young males live together in groups, while mature males (bulls) live solitary lives outside of the mating season. The females cooperate to protect and nurse their young. Females give birth every four to twenty years, and care for the calves for more than a decade. A mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of killer whales (orcas). Mature males average in length, with the head representing up to one-third of the animal's length. Plunging to , it is the third deep ...

Whale Oil
Whale oil is oil obtained from the blubber of whales. Whale oil from the bowhead whale was sometimes known as train oil, which comes from the Dutch word ''traan'' ("tears, tear" or "drop"). Sperm oil, a special kind of oil obtained from the head cavities of sperm whales, differs chemically from ordinary whale oil: it is composed mostly of liquid wax. Its properties and applications differ from those of regular whale oil, and it was sold for a higher price. Source and use Emerging industrial societies used whale oil in oil lamps and to Soap#History, make soap. In the 20th century it was made into margarine. With the commercial development of the petroleum industry and vegetable oils, the use of whale oils declined considerably from its peak in the 19th century into the 20th century. This is said to have saved whales from extinction. In the 21st century, with most countries having banned whaling, the sale and use of whale oil has practically ceased. Whale oil was obtained by ...

Capstan (nautical)
A capstan is a vertical- axled rotating machine developed for use on sailing ships to multiply the pulling force of seamen when hauling ropes, cables, and hawsers. The principle is similar to that of the windlass, which has a horizontal axle. History The word, connected with the Old French ''capestan'' or ''cabestan(t)'', from Old Provençal ''cabestan'', from ''capestre'' "pulley cord," from Latin ''capistrum'', -a halter, from ''capere'', to take hold of, seems to have come into English (14th century) from Portuguese or Spanish shipmen at the time of the Crusades. Both device and word are considered Spanish inventions. Early form In its earliest form, the capstan consisted of a timber mounted vertically through a vessel's structure which was free to rotate. Levers, known as bars, were inserted through holes at the top of the timber and used to turn the capstan. A rope wrapped several turns around the drum was thus hauled upon. A rudimentary ratchet was provided to hold t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baleen
Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have longer baleen than others. Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of whales. Depending on the species, a baleen plate can be long, and weigh up to . Its hairy fringes are called baleen hair or whalebone hair. They are also called baleen bristles, which in sei whales are highly calcified, with calcification functioning to increase their stiffness. Baleen plates are broader at the gumline (base). The plates have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baleen Whale
Baleen whales (systematic name Mysticeti), also known as whalebone whales, are a parvorder of carnivorous marine mammals of the infraorder Cetacea (whales, dolphins and porpoises) which use keratinaceous baleen plates (or "whalebone") in their mouths to sieve planktonic creatures from the water. Mysticeti comprises the families Balaenidae (right and bowhead whales), Balaenopteridae (rorquals and the gray whale), and Cetotheriidae (the pygmy right whale). There are currently 16 species of baleen whales. While cetaceans were historically thought to have descended from mesonychids, molecular evidence instead supports them as a clade of even-toed ungulates (Artiodactyla). Baleen whales split from toothed whales (Odontoceti) around 34 million years ago. Baleen whales range in size from the and pygmy right whale to the and blue whale, the largest known animal to have ever existed. They are sexually dimorphic. Baleen whales can have streamlined or large bodies, depending on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange (fruit)
An orange is a fruit of various citrus species in the family (biology), family Rutaceae (see list of plants known as orange); it primarily refers to Citrus × sinensis, ''Citrus'' × ''sinensis'', which is also called sweet orange, to distinguish it from the related ''Citrus × aurantium'', referred to as bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet orange arise through mutations. The orange is a Hybrid (biology), hybrid between pomelo (''Citrus maxima'') and Mandarin orange, mandarin (''Citrus reticulata''). The chloroplast genome, and therefore the maternal line, is that of pomelo. The sweet orange has had its full Whole genome sequencing, genome sequenced. The orange originated in a region encompassing Southern China, Northeast India, and Myanmar, and the earliest mention of the sweet orange was in Chinese literature in 314 BC. , orange trees were found to be the most Tillage, cultivated fruit tree in the wo ...

Mincing Blubber
Mincing is a food preparation technique in which food ingredients are finely divided into uniform pieces. Minced food is in smaller pieces than diced or chopped foods, and is often prepared with a chef's knife or food processor, or in the case of meat by a specialised meat grinder. For a true mince, the effect is to create a closely bonded mixture of ingredients and a soft or pasty texture. However, in many recipes, the intention is for firmer foods such as onions and other root vegetables to remain in individual chunks when minced. Flavoring ingredients such as garlic, ginger, and fresh herbs may be minced in this way to distribute flavor more evenly in a mixture. Additionally bruising of the tissue can release juices and oils to deliver flavors uniformly in a sauce. Mincemeat tarts/mince pies and pâté ''Pâté'' ( , , ) is a paste, pie or loaf filled with a forcemeat. Common forcemeats include ground meat from pork, poultry, fish or beef; fat, vegetables, herbs, spices ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool (or drum) attached to a hand crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a Mechanical brake stretch wrapper, mechanical brake or ratchet (device), ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may be stored on the winch. When trimming a line on a sailboat, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
