In agriculture, a pulper is a machine designed to remove pulp (i.e. the soft flesh) from agricultural produce. For example, in coffee growing, the ripe red cherries are picked from the coffee bushes and, before fermentation and later drying, the soft pulp needs to be removed (otherwise a potentially uncontrollable fermentation/rot will occur). In the case of coffee, the pulping is normally done in a pulper that is either hand-cranked or engine-driven; the beans come into contact with a rotating spiked drum that removes the pulp or flesh. The sticky beans that result from this process then have to be washed, fermented, washed again and dried, before further processing (milling to remove the parchment) and then roasting.
In paper making, a pulper is a machine that produces pulp from cellulose fibres; this pulp can directly be used by a paper machine. [1] In fufu powder making, a pulper is a machine that is used to pulp the fermented cassava to remove Fibre before sedimentation. [2]
Post-consumer waste is re-pulped, in one of the processes involved in recycling it.
The cocoa bean, also known simply as cocoa or cacao, is the dried and fully fermented seed of Theobroma cacao, the cacao tree, from which cocoa solids and cocoa butter can be extracted. Cacao trees are native to the Amazon rainforest. They are the basis of chocolate and Mesoamerican foods including tejate, an indigenous Mexican drink.
Sisal is a species of flowering plant native to southern Mexico, but widely cultivated and naturalized in many other countries. It yields a stiff fibre used in making rope and various other products. The sisal fibre is traditionally used for rope and twine, and has many other uses, including paper, cloth, footwear, hats, bags, carpets, geotextiles, and dartboards. It is also used as fibre reinforcements for composite fibreglass, rubber, and concrete products. It can also be fermented and distilled to make mezcal.
Papermaking is the manufacture of paper and cardboard, which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is made using industrial machinery, while handmade paper survives as a specialized craft and a medium for artistic expression.
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.
Pulpwood can be defined as timber that is ground and processed into a fibrous pulp. It is a versatile natural resource commonly used for paper-making but also made into low-grade wood and used for chips, energy, pellets, and engineered products.
A paper machine is an industrial machine which is used in the pulp and paper industry to create paper in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven mesh to create a continuous paper web by filtering out the fibres held in a paper stock and producing a continuously moving wet mat of fibre. This is dried in the machine to produce a strong paper web.
Carbonic maceration is a winemaking technique, often associated with the French wine region of Beaujolais, in which whole grapes are fermented in a carbon dioxide rich environment before crushing. Conventional alcoholic fermentation involves crushing the grapes to free the juice and pulp from the skin with yeast serving to convert sugar into ethanol. Carbonic maceration ferments most of the juice while it is still inside the grape, although grapes at the bottom of the vessel are crushed by gravity and undergo conventional fermentation. The resulting wine is fruity with very low tannins. It is ready to drink quickly but lacks the structure for long-term aging. In extreme cases such as Beaujolais nouveau, the period between picking and bottling can be less than six weeks.
Coffee production is the industrial process of converting the raw fruit of the coffee plant into the finished coffee. The coffee cherry has the fruit or pulp removed leaving the seed or bean which is then dried. While all green coffee is processed, the method that is used varies and can have a significant effect on the flavor of roasted and brewed coffee. Coffee production is a major source of income for 12.5 million households, most in developing countries.
A pulp mill is a manufacturing facility that converts wood chips or other plant fiber sources into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical, or fully chemical methods. The finished product may be either bleached or non-bleached, depending on the customer requirements.
In West Africa, garri is the flour of the fresh starchy cassava root.
Coffee wastewater, also known as coffee effluent, is a byproduct of coffee processing. Its treatment and disposal is an important environmental consideration for coffee processing as wastewater is a form of industrial water pollution.
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses, or other vegetable sources in water, draining the water through a fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, currency, and security paper, or in a number of industrial and construction processes.
Indonesia was the fourth-largest producer of coffee in the world in 2014. Coffee cultivation in Indonesia began in the late 1600s and early 1700s, in the early Dutch colonial period, and has played an important part in the growth of the country. Indonesia is geographically and climatologically well-suited for coffee plantations, near the equator and with numerous interior mountainous regions on its main islands, creating well-suited microclimates for the growth and production of coffee.
Giling Basah is a term used by Indonesian coffee processors to describe the method they use to remove the hulls of Coffea arabica. Literally translated from Indonesian, the term means "wet grinding".
Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp.
Haathi Chaap is a brand of paper manufactured in Rajasthan, India, out of elephant dung. The name comes from 'Haathi', meaning 'Elephant' in Hindi and 'Chaap' which means 'press' or 'imprint'. Elephant dung paper was probably first made in Thailand. Other than in India, elephant dung paper is also being manufactured in Sri Lanka and South Africa.
Air-laid paper is a textile-like material categorized as a nonwoven fabric made from fluff pulp.
Cassava production is vital to the economy of Nigeria as the country is the world's largest producer of the commodity. The crop is produced in 24 of the country's 36 states. In 1999, Nigeria produced 33 million tonnes, while a decade later, it produced approximately 45 million tonnes, which is almost 19% of production in the world. The average yield per hectare is 10.6 tonnes.
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.
