Packing House
A packing house is a facility where fruit is received and processed prior to distribution to market. Bulk fruit (such as apples, oranges, pears, and the like) is delivered to the plant via trucks or wagons, where it is dumped into receiving bins and sorted for quality and size. In the case of citrus, ripe fruit with a greenish tint is placed in special storage rooms where ethylene gas is used to bring out the color. Obvious "culls" (fruit that is not suitable to sell for eating due to cosmetic defects) is removed and sold for juice or other uses. Fruit that is ready to be packed into crates or flats is run through a washer and then air-dried. A light coating of natural wax is applied to help the fruit retain moisture and enhance its appeal. The fruit is transported via conveyor belts to the grading tables where it is visually sorted into three grades: ''top quality'', ''average'', and ''orchard run'', and is then carried via belts to the packing tables. During the late 19th cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple And Pear Packing Plant Pateros WA
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more ...

Citrus
''Citrus'' is a genus of flowering plant, flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as Orange (fruit), oranges, Lemon, lemons, grapefruits, pomelos, and lime (fruit), limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia (continent), Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethylene
Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula or . It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds). Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016) exceeds that of any other organic compound. Much of this production goes toward polyethylene, a widely used plastic containing polymer chains of ethylene units in various chain lengths. Ethylene is also an important natural plant hormone and is used in agriculture to force the ripening of fruits. The hydrate of ethylene is ethanol. Structure and properties This hydrocarbon has four hydrogen atoms bound to a pair of carbon atoms that are connected by a double bond. All six atoms that comprise ethylene are coplanar. The H-C-H angle is 117.4°, close to the 120° for ideal sp² hybridized carbon. The molecule is also relatively weak: rota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit Waxing
Fruit waxing is the process of covering fruits (and, in some cases, vegetables) with artificial waxing material. Natural wax is removed first, usually by washing, followed by a coating of a biological or petroleum derived wax. Potentially allergenic proteins (peanut, soy, dairy, wheat) may be combined with shellac. The primary reasons for waxing are to prevent water loss (making up for the removal in washing of the natural waxes in fruits that have them, particularly citrus but also, for example, applesP. E. Kolattukudy"Natural Waxes on Fruits", ''Post Harvest Pomology Newsletter'' 2.2 (1984), repr.

Tissue Paper
Tissue paper or simply tissue is a lightweight paper or, light crêpe paper. Tissue can be made from recycled pulp (paper), paper pulp on a paper machine. Tissue paper is very versatile, and different kinds of tissue are made to best serve these purposes, which are hygienic tissue paper, facial tissues, paper towels, as packing material, among other (sometimes creative) uses. The use of tissue paper is common in developed nations, around 21 million tonnes in North America and 6 million in Europe, and is growing due to urbanization. As a result, the industry has often been scrutinized for deforestation. However, more companies are presently using more recycled fibres in tissue paper. Properties The key properties of tissues are absorbency, basis weight, thickness, bulk (specific volume), brightness, stretch, appearance and comfort. Production Tissue paper is produced on a Fourdrinier machine, paper machine that has a single large steam heated drying cylinder (Yankee dryer) fi ...

Orange, California
Orange is a city located in North Orange County, California. It is approximately north of the county seat, Santa Ana, California, Santa Ana. Orange is unusual in this region because many of the homes in its Old Town District were built before 1920. While many other cities in the region demolished such houses in the 1960s, Orange decided to preserve them. The small city of Villa Park, California, Villa Park is surrounded by the city of Orange. The population was 139,911 as of 2020 United States Census, 2020. History Members of the Tongva and Juaneño/Luiseño ethnic group long inhabited this area. After the 1769 expedition of Gaspar de Portolá, an expedition out of San Blas, Nayarit, Mexico, led by Father Junípero Serra, named the area Vallejo de Santa Ana (Valley of Saint Anne). On November 1, 1776, Mission San Juan Capistrano became the area's first permanent European settlement in Alta California, New Spain. In 1801, the Spanish Empire granted to José Antonio Yorba, w ...

Sunkist Growers, Incorporated
Sunkist Growers, Incorporated is an American citrus growers' non-stock membership cooperative composed of 6,000 members from California and Arizona. It is currently headquartered in Valencia, California. Through 31 offices in the United States and Canada and four offices outside North America, its sales in 1991 totaled $956 million. It is the largest fresh produce shipper in the United States, the most diversified citrus processing and marketing operation in the world, and one of California's largest landowners. History In the late 1880s, California citrus growers began organizing themselves into cooperatives, with the goal of increasing profits by pooling their risk and increasing their collective bargaining power with jobbers and packers. The economic depression that began in 1893 worsened farmers' situations, and intensified their desire to self-organize to their own benefit. In 1893, P.J. Dreher and his son, the "father of the California citrus industry" Edward L. Dreher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Insulation
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced, creating a thermal break or thermal barrier, or thermal radiation is reflected rather than absorbed by the lower-temperature body. The insulating capability of a material is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability ( resistance value). In thermal engineering, other important properties of insulating materials are product density (ρ) and specific heat capacity (c). Definition T ...

Boxcars
A boxcar is the North American ( AAR) term for a railroad car that is enclosed and generally used to carry freight. The boxcar, while not the simplest freight car design, is considered one of the most versatile since it can carry most loads. Boxcars have side sliding doors of varying size and operation, and some include end doors and adjustable bulkheads to load very large items. Similar covered freight cars outside North America are covered goods wagons and, depending on the region, are called ''goods van'' ( UK and Australia), ''covered wagon'' ( UIC and UK) or simply ''van'' (UIC, UK and Australia). Use Boxcars can carry most kinds of freight. Originally they were hand-loaded, but in more recent years mechanical assistance such as forklifts have been used to load and empty them faster. Their generalized design is still slower to load and unload than specialized designs of car, and this partially explains the decline in boxcar numbers since World War II. The other ...

Refrigerator Car
A refrigerator car (or "reefer") is a refrigerated boxcar (U.S.), a piece of railroad rolling stock designed to carry perishable freight at specific temperatures. Refrigerator cars differ from simple insulated boxcars and ventilated boxcars (commonly used for transporting fruit), neither of which are fitted with cooling apparatus. Reefers can be ice- cooled, come equipped with any one of a variety of mechanical refrigeration systems, or utilize carbon dioxide (either as dry ice, or in liquid form) as a cooling agent. Milk cars (and other types of "express" reefers) may or may not include a cooling system, but are equipped with high-speed trucks and other modifications that allow them to travel with passenger trains. History Background: North America After the end of the American Civil War, Chicago, Illinois emerged as a major railway center for the distribution of livestock raised on the Great Plains to Eastern markets. Transporting the animals to market required herds to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slaughterhouse
A slaughterhouse, also called abattoir (), is a facility where animals are slaughtered to provide food. Slaughterhouses supply meat, which then becomes the responsibility of a packaging facility. Slaughterhouses that produce meat that is not intended for human consumption are sometimes referred to as ''knacker's yards'' or ''knackeries''. This is where animals are slaughtered that are not fit for human consumption or that can no longer work on a farm, such as retired work horses. Slaughtering animals on a large scale poses significant issues in terms of logistics, animal welfare, and the environment, and the process must meet public health requirements. Due to public aversion in different cultures, determining where to build slaughterhouses is also a matter of some consideration. Frequently, animal rights groups raise concerns about the methods of transport to and from slaughterhouses, preparation prior to slaughter, animal herding, and the killing itself. History Unti ...
