A grain elevator or grain terminal is a facility designed to stockpile or store grain. In the grain trade, the term "grain elevator" also describes a tower containing a bucket elevator or a pneumatic conveyor, which scoops up grain from a lower level and deposits it in a silo or other storage facility.
Bulk material handling is an engineering field that is centered on the design of equipment used for the handling of dry materials. Bulk materials are those dry materials which are powdery, granular or lumpy in nature, and are stored in heaps. Examples of bulk materials are minerals, ores, coal, cereals, woodchips, sand, gravel, clay, cement, ash, salt, chemicals, grain, sugar, flour and stone in loose bulk form. It can also relate to the handling of mixed wastes. Bulk material handling is an essential part of all industries that process bulk ingredients, including: food, beverage, confectionery, pet food, animal feed, tobacco, chemical, agricultural, polymer, plastic, rubber, ceramic, electronics, metals, minerals, paint, paper, textiles and more.
Kid Spark Education is a nonprofit organization that develops and produces affordable Mobile STEM Labs and curriculum for Schools and Youth Service Organizations. The Rokenbok Toy Company was founded in 1995 by Paul Eichen in the United States to create an heirloom quality toy system. The first Rokenbok toys debuted at the 1997 American International Toy Fair in New York City. In 2010 the company made a substantial push researching the effect of media, like Rokenbok, on developing minds. In 2015 the company transitioned into a 501(c)(3) and completed the development of their first 4 classroom specific products called Mobile STEM Labs. Since then, Kid Spark Education has placed Mobile STEM Labs in over 22 states across the country.
A granary, also known as a grain house and historically as a granarium in Latin, is a post-harvest storage building primarily for grains or seeds. Granaries are typically built above the ground to prevent spoilage and protect the stored grains or seeds from rodents, pests, floods, and adverse weather conditions. They also assist in drying the grains to prevent mold growth. Modern granaries may incorporate advanced ventilation and temperature control systems to preserve the quality of the stored grains.
A silo is a structure for storing bulk materials.
Acoustic cleaning is a maintenance method used in material-handling and storage systems that handle bulk granular or particulate materials, such as grain elevators, to remove the buildup of material on surfaces. An acoustic cleaning apparatus, usually built into the material-handling equipment, works by generating powerful sound waves which shake particulates loose from surfaces, reducing the need for manual cleaning.
A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat, bone meal, municipal solid waste, and many others. The first type of screw conveyor was the Archimedes' screw, used since ancient times to pump irrigation water.
For environmental remediation, Low-temperature thermal desorption (LTTD), also known as low-temperature thermal volatilization, thermal stripping, and soil roasting, is an ex-situ remedial technology that uses heat to physically separate petroleum hydrocarbons from excavated soils. Thermal desorbers are designed to heat soils to temperatures sufficient to cause constituents to volatilize and desorb from the soil. Although they are not designed to decompose organic constituents, thermal desorbers can, depending upon the specific organics present and the temperature of the desorber system, cause some organic constituents to completely or partially decompose. The vaporized hydrocarbons are generally treated in a secondary treatment unit prior to discharge to the atmosphere. Afterburners and oxidizers destroy the organic constituents. Condensers and carbon adsorption units trap organic compounds for subsequent treatment or disposal.
A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete. Some of these inputs include water, air, admixtures, sand, aggregate, fly ash, silica fume, slag, and cement. A concrete plant can have a variety of parts and accessories, including: mixers, cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors.
Malting is the process of steeping, germinating and drying grain to convert it into malt. Germination and sprouting involve a number of enzymes to produce the changes from seed to seedling and the malt producer stops this stage of the process when the required enzymes are optimal. Among other things, the enzymes convert starch to sugars such as maltose, maltotriose and maltodextrines.
Dry pasta lines are machines that make dry pasta products such as spaghetti or penne on a commercial scale, used for high-volume continuous production ranging from 500 to 8,000 kg per hour capacity. A typical dry pasta line consists of an extruder and a dryer. Modern machines are highly automated using programmable logic controllers. They are called "lines" because they contain a series of processing machines through which the dough passes. It is common for dry pasta lines to run continuously for up to six weeks, with packaging done in shifts.
Grain entrapment, or grain engulfment, occurs when a person becomes submerged in grain and cannot get out without assistance. It most frequently occurs in grain bins and other storage facilities such as silos or grain elevators, or in grain transportation vehicles, but has also been known to occur around any large quantity of grain, even freestanding piles outdoors. Usually, unstable grain collapses suddenly, wholly or partially burying workers who may be within it. Entrapment occurs when victims are partially submerged but cannot remove themselves; engulfment occurs when they are completely buried within the grain. Engulfment has a very high fatality rate.
Grain damage is any degradation in the quality of grain. In the current grain trade, this damage can affect price, feed quality, food product quality, and susceptibility to pest contamination.
There are a number of occupational hazards of grain facilities. These hazards can be mitigated through diligence and following proper safety procedures. Grain facility occupation exposure is the quantifiable expression of workplace health and safety hazards to which a grain-handling facility employee is vulnerable in performing their assigned duties. Exposure represents the probability that a given hazard will have some level of effect of a receptor of interest. This page uses data and information about grain facility occupational exposure in the United States.
Grain drying is the process of drying grain to prevent spoilage during storage. Artificial grain drying uses fuel or electricity powered processes supplementary to natural ones, including swathing/windrowing for air and sun drying, or stooking before threshing.
Kingaroy Peanut Silos are heritage-listed silos at 117–131 Haly Street, Kingaroy, South Burnett Region, Queensland, Australia. They were designed by Thomas Robinson & Son and Macdonald Wagner Consulting Engineers and built in 1938 by Kell & Rigby. They were added to the Queensland Heritage Register on 8 October 2010.
A grain hopper trailer is a trailer pulled by a semi tractor and used to haul bulk commodity products, such as grain. These trailers are used extensively throughout the United States to transport agricultural products as well as any other commodity that can be hauled in bulk and loaded and unloaded through the trailer.
Grain storage on a subsistence farm is primarily based on minimizing grain loss. In modern agricultural practices there are methods of managing under 1% grain loss, but small subsistence farms can see 20% - 100% of grain loss. This causes starvation and an unstable food supply. Grain loss can be caused by mold growth, bugs, birds, or any other contamination.
Kairi Maize Silos are heritage-listed silos at 22 Godfrey Road, Kairi, Tablelands Region, Queensland, Australia. They were designed and built in 1924 by Henry Simon Ltd. They were added to the Queensland Heritage Register on 8 August 2007.
