A decorticator (from Latin: cortex, bark) is a machine for stripping the skin, bark, or rind off nuts, wood, plant stalks, grain, etc., in preparation for further processing.
A decorticator (from Latin: cortex, bark) is a machine for stripping the skin, bark, or rind off nuts, wood, plant stalks, grain, etc., in preparation for further processing.
In 1933, a farmer named Bernagozzi from Bologna manufactured a machine called a "scavezzatrice", a decorticator for hemp. [1] A working hemp decorticator from 1890, manufactured in Germany, is preserved in a museum in Bologna. [2]
In Italy, the"scavezzatrice" faded in the 1950s because of monopolisation from fossil fuel, paper interests, synthetic materials and from other less profitable crops.
Many types of decorticators have been developed since 1890.[ citation needed ]
In 1919, George Schlichten received a U.S. patent on his improvements of the decorticator for treating fiber bearing plants. [3] Schlichten failed to find investors for production of his decorticator and died in 1923, a broken man. His business was revived a decade after death in 1933. [4] [5]
Newer, high-speed kinematic decorticators, use a different mechanism, enabling separation into three streams; bast fibre, hurd, and green microfiber.
In some decorticators, the operation is "semi-automatic", featuring several stops during operation, while more modern systems, such as high-speed kinematic decorticators, are fully automatic.
There are companies who produce and sell decorticators for different crops.
A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems.
The Marihuana Tax Act of 1937, Pub. L.Tooltip Public Law 75–238, 50 Stat. 551, enacted August 2, 1937, was a United States Act that placed a tax on the sale of cannabis. The H.R. 6385 act was drafted by Harry Anslinger and introduced by Rep. Robert L. Doughton of North Carolina, on April 14, 1937. The Seventy-fifth United States Congress held hearings on April 27, 28, 29th, 30th, and May 4, 1937. Upon the congressional hearings confirmation, the H.R. 6385 act was redrafted as H.R. 6906 and introduced with House Report 792. The Act is referred to, using the modern spelling, as the 1937 Marijuana Tax Act. It was overturned in 1969 in Leary v. United States, and was repealed by Congress the next year.
Automation describes a wide range of technologies that reduce human intervention in processes, mainly by predetermining decision criteria, subprocess relationships, and related actions, as well as embodying those predeterminations in machines. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic devices, and computers, usually in combination. Complicated systems, such as modern factories, airplanes, and ships typically use combinations of all of these techniques. The benefit of automation includes labor savings, reducing waste, savings in electricity costs, savings in material costs, and improvements to quality, accuracy, and precision.
Pulp is a fibrous lignocellulosic material prepared by chemically, semi-chemically or mechanically producing cellulosic fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemicals or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products.
Jack Herer, sometimes called the "Emperor of Hemp", was an American cannabis rights activist and the author of the 1985 book The Emperor Wears No Clothes. Herer founded and served as the director of the organization Help End Marijuana Prohibition (HEMP).
A mechanical calculator, or calculating machine, is a mechanical device used to perform the basic operations of arithmetic automatically, or (historically) a simulation such as an analog computer or a slide rule. Most mechanical calculators were comparable in size to small desktop computers and have been rendered obsolete by the advent of the electronic calculator and the digital computer.
Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope.
A transmission is a mechanical device which uses a gear set—two or more gears working together—to change the speed or direction of rotation in a machine. Many transmissions have multiple gear ratios, but there are also transmissions that use a single fixed-gear ratio.
In machining, numerical control, also called computer numerical control (CNC), is the automated control of tools by means of a computer. It is used to operate tools such as drills, lathes, mills, grinders, routers and 3D printers. CNC transforms a piece of material into a specified shape by following coded programmed instructions and without a manual operator directly controlling the machining operation.
Hemp, or industrial hemp, is a plant in the botanical class of Cannabis sativa cultivars grown specifically for industrial and consumable use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.
Frigidaire Appliance Company is the American consumer and commercial home appliances brand subsidiary of multinational company Electrolux, a Swedish multinational home appliance manufacturer, headquartered in Stockholm.
Textile manufacturing or textile engineering is a major industry. It is largely based on the conversion of fibre into yarn, then yarn into fabric. These are then dyed or printed, fabricated into cloth which is then converted into useful goods such as clothing, household items, upholstery and various industrial products.
In machining, a metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals; however, with the advent of plastics and other materials, and with their inherent versatility, they are used in a wide range of applications, and a broad range of materials. In machining jargon, where the larger context is already understood, they are usually simply called lathes, or else referred to by more-specific subtype names. These rigid machine tools remove material from a rotating workpiece via the movements of various cutting tools, such as tool bits and drill bits.
An automated guided vehicle (AGV), different from an autonomous mobile robot (AMR), is a portable robot that follows along marked long lines or wires on the floor, or uses radio waves, vision cameras, magnets, or lasers for navigation. They are most often used in industrial applications to transport heavy materials around a large industrial building, such as a factory or warehouse. Application of the automatic guided vehicle broadened during the late 20th century.
Manufacturing engineering or production engineering is a branch of professional engineering that shares many common concepts and ideas with other fields of engineering such as mechanical, chemical, electrical, and industrial engineering. Manufacturing engineering requires the ability to plan the practices of manufacturing; to research and to develop tools, processes, machines, and equipment; and to integrate the facilities and systems for producing quality products with the optimum expenditure of capital.
Wood-free paper is paper created exclusively from chemical pulp rather than mechanical pulp. Chemical pulp is normally made from pulpwood, but is not considered wood as most of the lignin is removed and separated from the cellulose fibers during processing, whereas mechanical pulp retains most of its wood components and can therefore still be described as wood. Wood-free paper is not as susceptible to yellowing as paper containing mechanical pulp. Wood-free paper offers several environmental and economic benefits, including reduced deforestation, decreased energy consumption, and improved waste management. The term Wood-free paper can be rather misleading or confusing for someone unfamiliar with the papermaking process because paper is normally made from wood pulp derived from trees and shrubs. However, wood free paper does not mean that the paper in question is not made from wood pulp but it means that the lignin in the wood fiber has been removed by a chemical process.
Factory automation infrastructure describes the process of incorporating automation into the manufacturing environment and processing of input goods into final products.
Cannabis in Italy is currently legal for medical and industrial uses, although it is strictly regulated, while it is decriminalized for recreational uses. In particular, the possession of small amounts of marijuana for personal use is a civil infraction. The possible sanctions for possession vary from the issuing of a diffida to first offenders, which is an injunction not to use the drug again; to the temporary suspension of certain personal documents for repeat offenders. Conversely, the unauthorized sale of cannabis-related products is illegal and punishable with imprisonment, as is the unlicensed cultivation of cannabis, although recent court cases have effectively established the legality of cultivating small amounts of cannabis for exclusively personal use. The licensed cultivation of cannabis for medical and industrial purposes requires the use of certified seeds; however, there is no need for authorization to plant certified seeds with minimal levels of psychoactive compounds.
Cannabis is illegal in Russia. Possession of up to 6 grams is an administrative offense, punishable by a fine or detention of 15 days. Possession of larger amounts is a criminal offense.
Hemp paper is a paper variety consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper, banknotes and technical filter papers. Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. Because the paper industry's processes have been optimized for wood as the feedstock, production costs currently are much higher than for paper from wood.
