Blade Grinder
A blade grinder, also known as propeller grinder, is a machine that chops material while mixing it, by means of a high-speed spinning blade. Applications of blade grinders for preparing foods include numerous electric kitchen appliances such as blenders (including immersion blenders), food processors, some garbage disposals, and some coffee grinders. The terms "blade grinder" and "propeller grinder" are in popular use to distinguish the blade grinder type of coffee grinder from other types. Other consumer applications include rotary lawn mowers. Design A blade grinder may be considered a type of hammermill. A blade grinder resembles a meat grinder in that both have propeller-shaped cutting blades. However, meat grinders (and food mills) use a scissor cutting action as the blades rotate against a perforated metal plate. Meat grinder blades rotate at a much slower speed than blade grinders, which may rotate at speeds as high as 20,000 to 30,000 rpm; for example, the Steele model mi ...

Electric Coffeegrinder
Electricity is the set of physics, physical Phenomenon, phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing Work (physics), work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an externa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeration
Aeration (also called aerification or aeriation) is the Systems engineering process, process by which air is circulated through, mixed with or solvation, dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration processes create additional surface area in the mixture, allowing greater chemical or suspension reactions. Aeration of liquids Methods Aeration of liquids (usually water) is achieved by: * passing air through the liquid by means of the Venturi tube, Aeration Turbine, aeration turbines or compressed air which can be combined with diffuser(s) air stone(s), as well as fine bubble diffusers, coarse bubble diffusers or linear aeration tubing. Ceramics are suitable for this purpose, often involving dispersion of fine air or gas bubbles through the porous ceramic into a liquid. The smaller the bubbles, the more gas is exposed to the liquid increasing the gas transfer efficiency. Diffusers or spargers can also be designed into the system to cause turbu ...

Cavitation
Cavitation is a phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. When subjected to higher pressure, these cavities, called "bubbles" or "voids", collapse and can generate shock waves that may damage machinery. These shock waves are strong when they are very close to the imploded bubble, but rapidly weaken as they propagate away from the implosion. Cavitation is a significant cause of wear in some engineering contexts. Collapsing voids that implode near to a metal surface cause cyclic stress through repeated implosion. This results in surface fatigue of the metal causing a type of wear also called "cavitation". The most common examples of this kind of wear are to pump impellers, and bends where a sudden change in the direction of liquid occurs. Cavitation is usually divided into two classes of behavior: inertial (or transient) cavitation and non-inertial c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blade
A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are to be used on. Historically, humans have made blades from flaking stones such as flint or obsidian, and from various metal such as copper, bronze and iron. Modern blades are often made of steel or ceramic. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes. Blades work by concentrating force on the cutting edge. Certain blades, such as those used on bread knives or saws, are serrated, further concentrating force on the point of each tooth. Uses During food preparation, knives are mainly used for slicing, chopping, and piercing. In combat, a blade may be used to slash or puncture, and may also be thrown or otherwise propelled. The function is to sever a nerve, muscle or tendon fibers, or bloo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardamom
Cardamom (), sometimes cardamon or cardamum, is a spice made from the seeds of several plants in the genera ''Elettaria'' and ''Amomum'' in the family Zingiberaceae. Both genera are native to the Indian subcontinent and Indonesia. They are recognized by their small seed pods: triangular in cross-section and spindle-shaped, with a thin, papery outer shell and small, black seeds; ''Elettaria'' pods are light green and smaller, while ''Amomum'' pods are larger and dark brown. Species used for cardamom are native throughout tropical and subtropical Asia. The first references to cardamom are found in Sumer, and in the Ayurvedic literatures of India. Nowadays it is also cultivated in Guatemala, Malaysia, and Tanzania. The German coffee planter Oscar Majus Klöffer introduced Indian cardamom to cultivation in Guatemala before World War I; by 2000, that country had become the biggest producer and exporter of cardamom in the world, followed by India.

Paste (food)
A food paste is a semi-liquid colloidal suspension, emulsion, or aggregation used in food preparation or eaten directly as a spread. Pastes are often highly spicy or aromatic, are often prepared well in advance of actual usage, and are often made into a preserve for future use. Common pastes are some fruit preserves, curry pastes, and nut pastes. Purées are food pastes made from already cooked ingredients. Some food pastes are considered to be condiments and are used directly, while others are made into sauces, which are more liquidy than paste. Ketchup and prepared mustard are pastes that are used both directly as condiments and as ingredients in sauces. Many food pastes are an intermediary stage in the preparation of food. Perhaps the most notable of such intermediary food pastes is dough. A paste made of fat and flour and often stock or milk is an important intermediary for the basis for a sauce or a binder for stuffing, whether called a '' beurre manié'', a roux or panada ...

Purée
A purée (or mash) is cooked food, usually vegetables, fruits or legumes, that has been ground, pressed, blended or sieved to the consistency of a creamy paste or liquid. Purées of specific foods are often known by specific names, e.g., applesauce or hummus. The term is of French origin, where it meant in Old French (13th century) ''purified'' or ''refined''. Purées overlap with other dishes with similar consistency, such as thick soups, creams (''crèmes'') and gravies—although these terms often imply more complex recipes and cooking processes. ''Coulis'' (French for "strained") is a similar but broader term, more commonly used for fruit purées. The term is not commonly used for paste-like foods prepared from cereal flours, such as gruel or muesli; nor with oily nut pastes, such as peanut butter. The term "paste" is often used for purées intended to be used as an ingredient, rather than eaten. Purées can be made in a blender, or with special implements such as a potat ...

The Joy Of Cooking
''Joy of Cooking'', often known as "''The Joy of Cooking''", is one of the United States' most-published cookbooks. It has been in print continuously since 1936 and has sold more than 20 million copies. It was published privately during 1931 by Irma S. Rombauer (1877–1962), a homemaker in St. Louis, Missouri, after her husband's suicide the previous year. Rombauer had 3,000 copies printed by A.C. Clayton, a company which had printed labels for fancy St. Louis shoe companies and for Listerine mouthwash, but never a book. Beginning in 1936, the book was published by a commercial printing house, the Bobbs-Merrill Company. With nine editions, ''Joy of Cooking'' is considered the most popular American cookbook. Background Born to German immigrants in 1877, Irma Starkloff was born and grew up in St. Louis, Missouri. She married Edgar Rombauer, a lawyer, during 1899. Edgar committed suicide after a severe bout of depression during 1930, widowing Irma at age 52, and leaving her wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortar And Pestle
Mortar and pestle is a set of two simple tools used from the Stone Age to the present day to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, laboratory, and pharmacy. The ''mortar'' () is characteristically a bowl, typically made of hard wood, 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, and rotated into the substance until the desired texture is achieved. Mortars and pestles have been used in cooking since prehistory; today they are typically associated with the profession of pharmacy 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; in masonry and in other typ ...

Burr Grinder
A burr mill, or burr grinder, is a mill used to grind hard, small food products between two revolving abrasive surfaces separated by a distance usually set by the user. When the two surfaces are set far apart, the resulting ground material is coarser, and when the two surfaces are set closer together, the resulting ground material is finer and smaller. Often, the device includes a revolving screw that pushes the food through. It may be powered electrically or manually. Burr mills do not heat the ground product by friction as much as blade grinders ("choppers"), and produce particles of a uniform size determined by the separation between the grinding surfaces. Food burr mills are usually manufactured for a single purpose: coffee beans, dried peppercorns, coarse salt, spices, or poppy seeds, for example. Coffee mills for volume consumption are usually powered by electric motors, but fast and precise manual mills have experienced an uptick in popularity in the 2020s for individual- ...

Coffee Preparation
Coffee preparation is the process of turning coffee beans into a beverage. While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps: raw coffee beans must be roasted, the roasted coffee beans must then be ground, and the ground coffee must then be mixed with hot or cold water (depending on the method of brewing) for a specific time ( brewed), the liquid coffee extraction must be separated from the used grounds, and finally, if desired, the extracted coffee is combined with other elements of the desired beverage, such as sweeteners, dairy products, dairy alternatives, or toppings (such as shaved chocolate). Coffee is usually brewed hot, at close to the boiling point of water, immediately before drinking, yielding a hot beverage capable of scalding if splashed or spilled; if not consumed promptly, coffee is often sealed into a vacuum flask or insulated bottle to maintain its temperature. In most areas, coffee ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osterizer
Osterizer is a brand which has been used by John Oster Manufacturing Company, Oster Manufacturing for its line of blender (device), blenders since 1946. History It has been claimed to be the first mainstream brand of blender,Young though technically the Waring Products, Waring blender ''brand'' was introduced in 1937. In 1946, Oster acquired the Stevens Electric Company, which had received a patent on the liquifying blender in 1922. Oster itself was bought by Sunbeam Corporation in 1960. The blender Osterizer blenders tended towards heavy construction and motors. While this raised cost, many early-model Osterizers still function today, and are more powerful than a majority of contemporary consumer blenders. Popular culture Oster Platinum Face 60-Minute Timer celebrated the 80th Anniversary in December 2010. There is an Osterizer blender in the kitchen in the film ''Bumblebee (film), Bumblebee''. There is an Osterizer blender in the film “ET”. Sources * J. Hebey, ''Dom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
